Description

The present invention relates to a method for constructing a plurality of lattice-like bodies, such as welded wire meshes or net-like fences, which are embedded in concrete and are formed by vertical strips and horizontal strips arranged in a lattice shape.

When pouring concrete to construct a structure such as the floor of a building, multiple welded wire meshes are placed inside the concrete to increase the strength of the structure and to prevent cracks from occurring in the structure. It is buried.

FIG. 32 is an explanatory diagram illustrating a conventional welded wire mesh construction method, and in the figure, WM is a welded wire mesh. The welded wire mesh WM is formed by arranging a plurality of vertical strips W1, W1,... and horizontal strips W2, W2,... in a lattice shape, and the vertical strips W1, W1,... and the horizontal strips W2, W2,... The intersecting portions are fixed by welding to each other.

A formwork (not shown) is erected around the area to be constructed, and a plurality of welded wire meshes WM, WM, . . . are laid throughout the entire area within the formwork. At this time, the edges of the adjacent welded wire meshes WM, WM are arranged to overlap each other by a plurality of squares (the first square in FIG. 32). Next, the welded wire meshes WM, WM, ... are lifted in order, and spacers 30, 30, ... such as blocks are interposed between the construction target surface and the welded wire meshes WM, WM, ..., as shown in FIG. Welded wire meshes WM, WM, ... are placed on the spacers 30, 30, .... By supporting the welded metal meshes WM, WM, . . . on the spacers 30, 30, . . . in this manner, the welded metal meshes WM, WM, .

In order to prevent mutual misalignment from occurring in the overlapped portions of adjacent welded wire meshes WM, WM, even if stepped on by a worker working on the welded wire meshes, for example, a short piece of wire, etc. Both overlapping welded wire meshes WM, WM are bound to each other by binding members B, B, . . . made of strips. After completing the construction of the welded wire meshes WM, WM, ... in the construction target area in this way, concrete is poured into the formwork to a predetermined depth where the welded wire meshes WM, WM, ... are embedded, and the poured concrete is It smoothes the surface.

However, such binding work needs to be performed on all areas where each welded wire mesh WM, WM, ... overlaps with each other, and there are many binding points in each area, so it is difficult to compare When constructing a structure with a large area, multiple skilled workers are required, and even skilled workers take a long time to complete the work at all the tie points. Ta.

Therefore, Patent Document 1, which will be described later, describes a plurality of horizontal strips made of steel bars for reinforced concrete and a plurality of vertical strips made of synthetic resin material or metal material shaped into strings or strips. A pre-assembled wire mesh connected in a blind-like manner has been proposed. In such a wire mesh, as before, the edges of adjacent wire meshes are overlapped with each other, and the overlapping portions of both wire meshes are bound together, but since the area of the wire mesh is wider than the welded wire mesh WM described above, it is difficult to bundle. There are fewer locations, so the time required for the bundling work can be shortened. On the other hand, this wire mesh can be wound into a roll around an axis that is parallel to the central axis of the horizontal strip material, making it easier to transport the wire mesh. By unwinding the welded wire mesh, the wire mesh can be laid out in the installation area, so the laying work can be performed more efficiently than in the case of laying the welded wire meshes WM, WM, . . . described above.

However, in any of the construction methods described above, the welded wire mesh WM or the wire mesh developed from a roll is simply placed on the spacers 30, 30, . . . , so the binding materials B, B, . When a shift occurs in each welded wire mesh WM, WM, . . . or each wire mesh during the bundling operation, there is a problem in that the positions of the spacers 30, 30, . Therefore, the following spacer is disclosed in Patent Document 2, which will be described later.

FIG. 33 is a perspective view showing how the spacer disclosed in Patent Document 2 is used. The spacer 131 is formed by bending and forming a metal wire with a diameter of about 5 to 6 mm, and is formed between two rising portions 131c, 131c that are spaced apart from each other by a predetermined distance, and between both rising portions 131c, 131c. The iron wire support part 131g supports the iron wire constituting the welded wire mesh, and the mounting parts 131b, 131b are bent horizontally from the lower ends of both rising parts 131c, 131c, and are placed on the deck plate DP. There is. The iron wire support portion 131g also includes lower horizontal portions 131d, 131d extending horizontally from the upper ends of both rising portions 131c, 131c, and arc-shaped portions curved and rising from both lower horizontal portions 131d, 131d, respectively. It has portions 131e, 131e and a horizontal upper horizontal portion 131f connecting the upper ends of both arcuate portions 131e, 131e, and has a flat spiral shape when viewed from the side. Here, the inner dimension between the lower horizontal portions 131d, 131d and the upper horizontal portion 131f is larger than the outer diameter of the iron wire constituting the welded wire mesh.

In such a spacer 131, the welded wire mesh WM laid on the deck plate DP is lifted, the iron wire constituting the welded wire mesh WM is inserted into the spiral iron wire support portion 131g, and in this state, the welded wire mesh WM is By lowering the wire mesh WM, the mounting portions 131b, 131b of the spacer 131 are brought into contact with the deck plate DP, and the spacer 131 is made to stand on the deck plate DP. At this time, the iron wire inserted into the iron wire support portion 131g is supported on both lower horizontal portions 131d, 131d of the spacer 131.

Japanese Patent Application Publication No. 9-209500 Japanese Patent Application Publication No. 2010-189855

However, in the spacer 131 disclosed in Patent Document 2, the work of inserting the iron wire of the welded wire mesh WM into the iron wire support portion 131g of the spacer 131 is performed by inserting each welded wire mesh WM partially overlapped with each other, as before. Since the worker has to lift the WM,..., there is a problem that not only is the worker forced to do heavy labor, but also that it takes a long time to attach the spacer 131 to the iron wire of the welded wire mesh WM. On the other hand, by inserting the iron wire constituting the welded wire mesh WM into the spiral iron wire support portion 131g, the spacer 131 follows the movement of the welded wire mesh WM after that, but the spacer 131 is not fixed to the welded wire mesh WM. Therefore, when a shift occurs in the welded wire mesh WM that has been laid and the position of the welded wire mesh WM is adjusted, the iron wire inserted into the iron wire support portion 131g of the spacer 131 will be inserted into the lower horizontal portions 131d, 131d. In such a case, the part of the welded wire mesh WM to which the spacer 131 was attached had to be lifted again and the spacer 131 had to be readjusted.

Furthermore, even when such a spacer 131 is used, in order to construct a plurality of welded wire meshes, each welded wire mesh must be bound together, and the above-mentioned problems associated with the bundling work remain unresolved.

The present invention has been made in view of such circumstances, and provides a method that allows even inexperienced workers to reliably construct multiple lattice structures in a short time without forcing the workers to do heavy labor. I will provide a.

(1) The method for constructing a lattice-like body according to the present invention is to join the intersections of a plurality of longitudinal members and a plurality of horizontal members arranged in a lattice pattern, and each longitudinal member and each horizontal member The edges of one grid-like body having multiple squares formed in the process are overlapped with the edges of the other grid-like body, and the overlapped parts of the two are repeatedly fixed to each other to form a surface to be constructed. A method for constructing a lattice-like body in which a plurality of lattice-like bodies are constructed, the arrangement position being a position where each lattice-like body is arranged, and the arrangement order being the order in which each lattice-like body is to be arranged, the method comprising: One or more fixing devices having a fixing part for fixing to the one grid-like body and a coupling means for coupling the vertical strips or horizontal strips of the other grid-like body are attached to each grid-like body. Fixed at a predetermined position on the edge of the body, on the edge of one grid-like body placed at the corresponding position according to the above arrangement order, another placed at the corresponding arrangement position according to the above arrangement order. One or more fixtures fixed to the edge of one grid-like body by overlapping the edges of the grid-like body and then applying pressure to the edges of the other superimposed grid-like body It is characterized in that the vertical strips or the horizontal strips of the other grid-like body are coupled to the coupling means of the above, thereby fixing both grid-like bodies.

In the method for constructing a lattice-like body of the present invention, the intersections of a plurality of longitudinal members and a plurality of horizontal members arranged in a lattice shape are joined, and each longitudinal member and each horizontal member are connected to each other. The edges of one grid-like body having a plurality of squares formed by the grid are overlapped with the edges of the other grid-like body, and the overlapped portions of the two are repeatedly fixed to each other. A grid structure will be constructed. At this time, on the surface to be constructed, the arrangement position, which is the position in which each grid-like body is arranged, and the arrangement order, which is the order in which each grid-like body is arranged, are determined in advance. Therefore, the constructor, who is a worker, only has to place each grid-like body in a predetermined arrangement position and in a predetermined arrangement order, and even an inexperienced constructor can easily place multiple grid-like bodies in a short time. can be placed securely. Here, the predetermined arrangement positions and arrangement order of the lattice-like bodies are obtained as a construction blueprint, so the builder can place each lattice-like body in the predetermined position according to the construction blueprint. Arrange in order of arrangement.

Further, in the present invention, a fixing portion for fixing to the one grid-like body and a coupling means for coupling the vertical strip members or the horizontal strip members of the other grid-like body are provided. Use multiple fixtures. That is, both adjacent lattice bodies are constructed on the surface to be constructed so that their edges overlap each other, but the edges of the two lattice bodies are constructed on the surface to be constructed so that their edges overlap with each other. One or more fixtures are fixed to predetermined positions on the edge using respective fixing parts provided on each fixture. Each of these fixtures is provided with a coupling means for coupling the vertical strips or horizontal strips constituting another grid-like body superimposed on the edge of the one grid-like body.

Then, according to the arrangement order, the edge of the other grid-like body arranged at the corresponding arrangement position is superimposed on the edge of one grid-like member arranged at the corresponding arrangement position according to the arrangement order. Next, by applying pressure to the edge of the other grid-like body superimposed on the other grid-like body, the coupling means of the one or more fixtures fixed to the edge of one grid-like body is connected to the other grid-like body. The vertical strips or horizontal strips of the lattice-shaped bodies are joined together to fix both the lattice-shaped bodies.

In this way, by simply superimposing the edge of the other grid-like body on the edge of one grid-like body to which the fixture is fixed, and applying pressure to the edge of the other grid-like body, the fixture can be fixed. Both lattice bodies can be connected and fixed with one touch. Since the conventional binding work is not required, even an inexperienced constructor can reliably construct multiple lattice-like bodies in a short time without forcing the constructor to do heavy labor.

In addition, depending on the arrangement order, each time a corresponding other grid-like body is placed at the placement position, pressure is applied to the edge of the other grid-like body, so that the grid-like body is Since it can be connected and fixed with one touch, construction work can be made as efficient as possible.

( 4 ) The method for constructing a lattice-like body according to the present invention is characterized in that when determining the arrangement order, front and back sides of the lattice-like body are determined.

In the method for constructing a lattice-like body of the present invention, when determining the arrangement order, the front and back sides of the lattice-like body are determined. For example, if each longitudinal member of the lattice is on the upper side and each horizontal member is on the lower side, the table is used, and vice versa, i.e., each longitudinal member of the lattice is on the lower side and each horizontal member is on the lower side. If the strip is on the upper side, it is the back, and if one grid is placed face up and the other grid is placed on the back, then the vertical strips on both grids will be Since the members are arranged so that they can face each other, both grid bodies can be arranged so that they are adjacent to each other in the same plane. Note that the definition of front and back may be the opposite. Here, since the front and back sides of the predetermined lattice-like bodies are obtained as a construction design drawing, the builder arranges each lattice-like body so that the front and back sides are the predetermined front and back sides according to the construction design drawing.

( 5 ) The method for constructing a lattice-like body according to the present invention is to alternately arrange the front lattice-like body and the back lattice-like body in the row direction of the construction target surface, and in the column direction of the construction target surface. Placing grid-like bodies with the same front and back sides, or placing grid-like bodies on the front side and grid-like bodies on the back side alternately in the column direction of the work surface, and also placing the same front and back faces in the row direction of the work target surface. It is characterized by the arrangement of grid-like bodies.

In the method for constructing a lattice-like body of the present invention, the front lattice-like body and the back lattice-like body are arranged alternately in the row direction of the construction target surface, and the front and back grid bodies are arranged alternately in the row direction of the construction target surface. Place the same grid. As before, each longitudinal member of the lattice-like body is on the upper side and each horizontal member is on the lower side. If the two grid bodies that are adjacent to each other in the row direction are arranged in the order of front and back, the vertical strips of both grid bodies are arranged so that they can face each other, so they can be Both grid bodies can be arranged adjacent to each other in the same plane. Furthermore, when both grid-like bodies adjacent to each other in the row direction are arranged front to back, the horizontal strips of both grid-like bodies are arranged so as to be able to face each other, so that they can be placed in opposition to each other within the same plane. Both grid bodies can be arranged next to each other. Thereby, the thickness of the portion where one lattice-like body and another lattice-like body are overlapped can be made as small as possible.

Alternatively, grid-like bodies on the front and grid-like bodies on the back are arranged alternately in the column direction of the surface to be constructed, and grid-like bodies having the same front and back sides are arranged in the row direction of the surface to be constructed. In this case, as before, when both grid-like bodies that are adjacent to each other in the column direction are arranged in the order of front and back, each longitudinal member of both grid-like bodies is arranged so that they can face each other, so they are placed on the same surface. Both lattice bodies can be arranged next to each other within the lattice structure. Furthermore, when both grid bodies that are adjacent to each other in the column direction are arranged in the order of front and back, the horizontal strips of both grid bodies are arranged so that they can face each other. Both grid bodies can be arranged next to each other. Thereby, the thickness of the portion where one lattice-like body and another lattice-like body are overlapped can be made as small as possible. Here, as before, the front and back sides of the lattice-like bodies are acquired as a construction design drawing, so the builder arranges each lattice-like body so that the front and back sides are predetermined according to the construction design drawing.

( 6 ) In the method for constructing a lattice-like body according to the present invention, when determining the placement position, the shape of each lattice-like body is determined based on the blueprint of the building related to the construction target surface, and the shape of each lattice-like body is determined in the determined shape. A feature is that each grid-like body is processed in advance.

Then, each grid-like body is processed into a predetermined shape. As a result, it is possible to obtain grid-like bodies having shapes according to the design drawings, and construction work for each grid-like body can be carried out in a shorter time. Here, since the shape of each lattice-like body is acquired as a construction design drawing, the builder processes each lattice-like body so that it has a shape according to the construction design drawing.

(1) In addition to the above (1), in the method for constructing a lattice-like body according to the present invention, the first lattice-like body and the other lattice-like body have squares of both facing the construction target surface. It is characterized in that the positions are superimposed so that they are different from each other.

In the method for constructing a lattice-like body of the present invention, the positions of the meshes of the one lattice-like body and the other lattice-like body facing the construction target surface are, for example, 1.5 times apart from each other. The grids are superimposed in different ways, such as overlapping the squares. As a result, it is possible to reduce the overlapping region of adjacent structural strengths while maintaining a high coupling strength, and therefore it is possible to reduce loss in the lattice body as much as possible. Here, since the positions of both grids facing the construction target surface of each grid body are acquired as a construction design drawing, the builder constructs each grid body according to the construction design drawing.

That is, the fixing device is equipped with a pair of fixing parts for fixing to the adjacent vertical strips or the adjacent horizontal strips of the above-mentioned one lattice body, and both of the pairs Coupling means are arranged in the area between the fixing parts. As mentioned above, when one grid-like body and another grid-like body are overlapped so that the positions of the grids of both bodies facing the construction target surface are different from each other, the adjacent grid-like bodies of one grid-like body Because the vertical strips or horizontal strips of another lattice-like body are located between the vertical strips or between the adjacent horizontal strips, the vertical strips or horizontal strips of the other lattice-shaped body are and to the coupling means of the fixture. As a result, both grid bodies can be combined and fixed with one touch.

( 2 ) In the method for constructing a lattice-like body according to the present invention, the fixing devices arranged at the edges of one lattice-like body adjacent to each other in the row direction are arranged so that the pair of fixing parts are placed next to each other in the lattice-like body. The vertical strips of other grid-like bodies adjacent in the row direction are connected to the coupling means of the fixing device, and the edges of one grid-like body adjacent in the column direction are The fixing device arranged in the row has its pair of fixing parts fixed to the adjacent horizontal strip members of the grid-like body, and the coupling means of the fixing device has the fixing parts of the fixing parts arranged in pairs fixed to the horizontal strip members adjacent to each other in the grid-like body, and It is characterized by joining horizontal strips.

The vertical strips of other grid-like bodies adjacent to each other in the row direction are coupled to the coupling means of the fixture. This prevents both grid bodies from sliding against each other in the row direction.

In addition, for fixing devices arranged at the edges of one grid-like body adjacent to each other in the row direction, the pair of fixing parts are fixed to the horizontal strips adjacent to each other in the grid-like body, and the fixing devices are The horizontal strip members of other grid-like bodies adjacent to each other in the row direction are coupled to the coupling means. This prevents both grid bodies from sliding against each other in the column direction. Therefore, the grid-like bodies constructed on the surface to be constructed are prevented from sliding relative to each other in the row and column directions as a whole. Here, since the attachment positions of the fixtures to each grid-like body are acquired as a construction blueprint, the builder attaches the fixtures to each grid-like body according to the construction blueprint.

Here, "approximately matching" means not only when the positions of the grids of both grids match, but also when the positions of the grids of both grids differ by one length of vertical strip or horizontal strip, that is, the vertical bars of both grid bodies. It also includes cases where strips or horizontal strips are superimposed next to each other in the same plane. When constructing multiple grid-like bodies on the construction target surface, the edges of one grid-like body are overlapped with the edges of other grid-like bodies so that the two squares match each other. However, it is compatible with this construction method. Here, since it is obtained as a construction design that one grid-like body and another grid-like body are overlapped so that the positions of their squares almost match, the builder should Construct the grid structure.

In addition, in order to hold the lattice-like body at a position separated by a predetermined distance from the surface to be constructed, the lattice-like body is Multiple types of spacers are used, each having a fixing part for fixing the grid and a supporting part for supporting the grid at a position separated from the surface to be constructed. The position to be fixed to, the mounting direction to be attached to the lattice-like body, and the type to be attached to the position are determined and included in the construction blueprint.

Then, according to the obtained construction design drawings, the builder processes a plurality of lattice bodies, attaches fixing tools and spacers corresponding to each of the processed lattice bodies, and arranges each lattice body to which they are attached in the order of arrangement. Accordingly, on the edge of one grid-like body placed at the corresponding placement position, the edge of another grid-like body placed at the corresponding placement position is superimposed on the edge of the other grid-like body placed at the corresponding placement position, and then By applying pressure to the edge of the other grid-like body, the longitudinal strips of the other grid-like body are When fixing both lattice-like bodies by joining timbers or horizontal strips, the first lattice-like body and the other lattice-like body are such that the positions of their squares facing the construction target surface are mutually mutual. The fixing means includes a pair of fixing parts for respectively fixing to adjacent vertical strips or adjacent horizontal strips of one lattice-like body, and the coupling means A fixing device is used which is disposed in the area between the pair of fixing parts.

In this way, the builder only has to carry out construction of each lattice-like body according to the construction design drawing, and even an inexperienced builder can reliably construct a plurality of lattice-like bodies in a short time. Furthermore, by simply superimposing the edge of one grid-like body on which the fixture is fixed on the edge of another grid-like body and applying pressure to the edge of the other grid-like body, the fixing fixture can Both lattice bodies can be connected and fixed with one touch, eliminating the need for the conventional binding work and requiring even an inexperienced builder to shorten multiple lattice bodies without requiring heavy labor. It can be constructed in a timely manner.

Needless to say.

(First form for carrying out the invention)
FIG. 1 is a flowchart showing an example of a procedure for carrying out the method for constructing a lattice-like body according to the present invention. In this embodiment, a case will be described in which a welded wire mesh is used as the lattice-like body and is mainly applied to the construction of the floor of a building.

As shown in Figure 1, the builder places a plurality of welded wire meshes on the surface to be constructed, fixes for fixing adjacent welded wire meshes with parts of them overlapping each other, and removes the welded wire meshes from the surface to be constructed. A construction design is performed that determines the arrangement of spacers and the like to be held at separate heights, the arrangement order of each welded wire mesh, etc. (step S1).

FIG. 2 is a flowchart showing detailed steps in implementing the construction design shown in FIG.
The constructor is responsible for the placement of aggregates such as steel frames that form the skeleton of the building, the placement of walls, columns, stairs, etc. of the building, and the placement of multiple deck plates to be installed between opposing aggregates. A blueprint of the building relating to the target surface is given in advance, and the builder places a plurality of welded wire meshes on the construction target surface defined in the blueprint (step S10). At this time, the predetermined areas of the edges of adjacent welded wire meshes are overlapped with each other. Each welded wire mesh arranged in this way may partially overlap structures such as walls, columns, stairs, etc. of buildings, and such welded wire meshes need to be shaped by cutting out the corresponding portions. There is. Therefore, the builder determines the shape of each welded wire mesh arranged in the design drawing so that there is no overlapped portion with the structure (step S11). Here, the design drawing according to the present invention includes not only printed matter but also design drawing data and images displaying the design drawing data.

FIG. 3 is an explanatory diagram illustrating a state in which a plurality of molded welded wire meshes are arranged on the above-mentioned design drawing, and in the diagram, DP is a deck plate. The deck plates DP, DP, ... are provided with, for example, two ridge-shaped peaks DM, DM and a valley DB between them, and a half of the valley DB is provided on the outside of both peaks DM, DM. Flange portions each having a width dimension are provided, and by connecting both opposing flange portions of adjacent deck plates DP, DP, the same valley portion DB as before is formed.

Note that the deck plate DP is provided with the flange portions on both sides of one peak portion DM, and the valley portion DB is formed by connecting both opposing flanges of two adjacent deck plates DP, DP. It may be configured as follows.

A plurality of aggregates are assembled to form the skeleton of the building, and as shown in Figure 3, deck plates DP, DP, ... are installed between the opposing aggregates to form the floor bottom of the building. In order to achieve this, a construction target surface excluding pillars P etc. is formed. As described above, each of the welded wire meshes WM, WM, . As described later, there are multiple squares M in the welded wire mesh WM.
, M, ... are provided, and in the case shown in Fig. 3, adjacent welded wire meshes WM, WM, ... have areas corresponding to 1.5 squares M of their edges overlapped with each other. .

FIG. 4 is a plan view showing one of the welded wire meshes shown in FIG. 3.
The welded wire mesh WM has a plurality of vertical strips W1, W1,... and a plurality of horizontal strips W2, W2,... arranged in a grid shape at a predetermined distance apart, and the intersections of the two are fixed by welding. There is. In addition, the welded wire mesh WM is formed such that a plurality of squares M, M, ... surrounded by each vertical strip member W1, W1, ... and each horizontal strip member W2, W2, ... are formed in a plurality of rows and a plurality of columns. has been done. Note that the vertical strips W1 and the horizontal strips W2 are named for convenience, and depending on the relative position of the welded wire mesh WM and the observer, the vertical strips W1 are arranged horizontally and the horizontal strips W2 are arranged vertically. Needless to say, there are cases in which it is arranged in the direction.

On the other hand, in the welded wire mesh WM shown in FIG. 4, the length dimensions of the vertical strips W1, W1,... are shorter than the length dimensions of the horizontal strips W2, W2,... A grid-like body is formed. In addition, each of the vertical strips W1, W1,... of the welded wire mesh WM is arranged in the same plane, and each of the horizontal strips W2, W2,... is arranged in a different plane, and the longitudinal strips W1, W1,... If the side located above the horizontal strips W2, W2,... is the front side of the welded wire mesh WM, then the side where the vertical strips W1, W1,... is located below the horizontal strips W2, W2,... is the front side of the welded wire mesh WM. It will be the back. Note that the length of the vertical strips W1, W1,... may be longer than the length of the horizontal strips W2, W2,..., and the length of the longitudinal strips W1, W1,... The length dimensions of the strips W2, W2, . . . may be the same.

As shown in FIG. 4, this welded wire mesh WM has a plurality of irregularities formed on its periphery in accordance with the shape of the wall and the shape of the pillars of the building.

In this way, once the position of each welded wire mesh on the construction target surface and the shape of each welded wire mesh are determined, the installer determines the order in which each welded wire mesh is to be installed and the front and back sides of each welded wire mesh ( Steps S12, S13). Then, for each welded wire mesh WM, WM, ... whose arrangement position, arrangement order, and front and back sides are determined, a fixture for mutually fixing the welded wire mesh WM and another welded wire mesh WM superimposed thereon, and welding An attachment position for attaching a spacer that holds the wire mesh WM, WM, . . . at a position separated from the construction target surface is determined (step S14). Then, the installer selects a first fixture and a first spacer corresponding to the peaks DM of the deck plate DP, or a second fixture and a second spacer corresponding to the valleys DB, as described later, and A construction design drawing is obtained by determining the mounting direction of the first fixture, the first spacer, the second fixture, or the second spacer (steps S15 and S16).

FIG. 5 is an explanatory diagram illustrating an example of a construction design drawing that defines the order in which welded wire meshes are constructed, the front and back sides of each welded wire mesh, and the mounting positions and mounting directions of fixtures and spacers. Note that in FIGS. 5 and 6, parts corresponding to those shown in FIG. 3 are given the same numbers and their explanations will be omitted. Moreover, FIG. 6 is an explanatory diagram for simplifying and explaining the construction order of the welded wire mesh shown in FIG. 5 and the front and back of each welder. In addition, in FIG. 5, the numbers inside the circles indicate the construction order. In addition, the uncolored welded wire mesh WM shows the front side with each vertical strip placed above each horizontal strip, while the colored welded wire mesh WM shows the back side with each vertical striped material positioned above each horizontal strip. It shows the back side of each horizontal strip.

As shown in FIGS. 5 and 6, a plurality of welded wire meshes WM, WM, ... are arranged in the vertical and horizontal directions, and adjacent welded wire meshes WM, WM, WM, WM, ..., The regions of 1.5 squares M of the section are overlapped with each other.

Also, the side where the vertical strips W1, W1, ... are located on the horizontal strips W2, W2, ... is the front side of the welded wire mesh WM, and the vertical strips W1, W1, ... are on the horizontal strips W2, W2,... When the side located below is the back side of the welded wire mesh WM, in the welded wire mesh WM on the front side, the vertical strips W1, W1,... are each shown as a solid line, and the horizontal strips W2, W2,... are each shown as a solid line. It is indicated by a broken line. On the other hand, in the back welded wire mesh WM, the vertical strips W1, W1, . . . are each indicated by broken lines, and the horizontal strips W2, W2, . . . are each indicated by solid lines.

In this embodiment, regarding the vertical strips W1, W1,... and the horizontal strips W2, W2,..., the one located relatively above is indicated by a solid line, and the one located relatively below is indicated by a broken line. However, it goes without saying that it is not limited to this. For example, the vertical strips W1, W1, ... and the horizontal strips W2, W2, ... are displayed as two lines, and the relative Alternatively, the lower two lines may be erased.

In the construction design drawings shown in this example, the welded wire mesh WM placed in the upper left corner of FIG. In the reverse state, the areas of 1.5 squares M on the short edges are arranged so as to overlap each other. Similarly, a third welded wire mesh WM is placed face-up to the right of the second welded wire mesh WM.

In this way, when the arrangement of the first row is completed, the fourth welded wire mesh WM is placed face-up on the lower side in front of the first welded wire mesh WM, and the 1.5 squares are placed on the long edge of the fourth welded wire mesh WM. The M regions are arranged so as to overlap each other. Next, to the right of this fourth welded wire mesh WM, place a fifth welded wire mesh WM and a sixth welded wire mesh WM in this order, and as before, place 1.5 squares M on the short edge of the fourth welded wire mesh WM. Complete the second row by arranging the regions so that they overlap each other. Note that the long edge portions of the fifth welded wire mesh WM and the sixth welded wire mesh WM, and the long edge portions of the second welded wire mesh WM and the third welded wire mesh WM are the squares of 1.5 pieces. The regions of the eyes M are overlapped with each other.

Then, after arranging the tenth welded wire mesh WM on the lower front side of the fourth welded wire mesh WM described above so that the area of 1.5 squares M on the long edge thereof overlaps with each other, To the right of this tenth welded wire mesh WM, place the eleventh welded wire mesh WM and the twelfth welded wire mesh WM in this order. Complete the placement of all welded wire mesh by arranging the areas so that they overlap each other.

As shown in FIG. 5, in this example, the welded wire meshes WM, WM, .

The order in which these welded wire meshes WM, WM, ... are placed is that they are placed in sequence in the horizontal or vertical direction starting from an appropriate position such as a corner, and when they are placed up to the terminal position of the row or column, the next It may be determined to move to the head position corresponding to the start position of the row or column, and sequentially arrange them in the horizontal or vertical direction from the head position.

As mentioned above, in this embodiment, the welded wire meshes WM, WM, ... in odd-numbered rows are in the front state, and the welded wire meshes in even-numbered rows WM, WM, ... are shown in the reversed state. The invention is not limited to this, and the welded wire meshes WM, WM, ... in odd-numbered rows may be placed on the back side, and the welded wire meshes WM, WM, ... on even-numbered rows may be placed on the front side. On the other hand, as shown in FIG. 7, the front and back sides of the welded wire meshes WM, WM, . . . adjacent to each other in the row and column directions may be arranged to be different.

In addition, in the case of the former arrangement example and the arrangement example shown in this embodiment in FIG. 5, compared to the latter arrangement example, the area where the four adjacent welded wire meshes WM, WM, WM, WM overlap each other is This is preferable because the thickness can be reduced.

Next, a fixture for fixing both the welded metal meshes WM, WM to each other is placed at an appropriate position in the overlapping region of the adjacent welded metal meshes WM, WM, WM, WM, . . . . At this time, if the placed position is a position facing the mountain parts DM, DM, ... of the deck plates DP, DP, ... shown in FIG. 3, while placing the first fixture F1, which will be described later, When the placed position is a position facing the valley portions DB, DB, . . . of the deck plates DP, DP, . . . shown in FIG. 3, a second fixture F2, which will be described later, is placed. Note that both the first fixture F1 and the second fixture F2 are attached to the welded wire mesh WM disposed on the lower side of the adjacent welded wire meshes WM, WM.

At this time, the first fixing devices F1, F1,... and/or the second fixing devices F2, F2,... Place it in As a result, the four adjacent welded wire meshes WM, WM, WM, WM can be firmly fixed to each other without arranging the first fixing device F1 or the second fixing device F2 at the relevant location, and each weld It is possible to prevent the wire meshes WMWM, WM, WM, WM from shifting in the vertical and horizontal directions.

Furthermore, first spacers SP1, SP1, . . . or second spacers SP2, SP2, . As before, if the position is opposite to the mountain parts DM, DM, ... of the deck plates DP, DP, ... shown in FIG. 3, the first spacer SP1 is also , . . ., the second spacer SP2 is disposed at a position opposite to the valley portions DB, DB, .

Note that the intervals at which the first fixtures F1, F1, ... or the second fixtures F2, F2, ... are installed, and the intervals at which the first spacers SP1, SP1, ... or the second spacers SP2, SP2, ... are installed are both Set to 900mm or less.

FIG. 8 is a perspective view showing an example of the first fixture F1.

The first fixture F1 includes a pair of first frame members 11, 11 formed by molding rod-shaped members into an inverted convex shape, and a pair of short rod-shaped second frame members 12, 12. Fixing portions 11e, 11e, 11e, 11e for fixing to the welded wire mesh are provided at both ends of the frame members 11, 11, respectively. The first frame members 11, 11 and the second frame members 12, 12 are fixed in a parallel grid shape when viewed from above, as will be described later.

The above-described first frame member 11 has a main body formed into a U-shape as a whole, with both ends of the straight-line contact portion 11b capable of contacting the construction target surface raised to form rising portions 11c, 11c. (Supporting part) 11a. At both ends of the main body 11a, short arm portions 11d, 11d extend in a direction substantially parallel to the contact portion 11b and away from each other, and the tip portions of both arm portions 11d, 11d The above-mentioned hook-shaped fixing parts 11e, 11e are formed by standing up in a posture parallel to the rising parts 11c, 11c and curving outward from each other. That is, both fixing portions 11e, 11e are both curved inwardly. In addition, although the case where the contact part 11b in the shape of a straight line is provided in this embodiment is shown, the present invention is not limited to this, and may have an appropriate shape such as an uneven shape or a wavy line shape.

The dimension between the inner bottoms of both fixing parts 11e and 11e provided on the first frame member 11 is the outer dimension between adjacent vertical strips that constitute the welded wire mesh to which the first fixture F1 is attached, or the dimension between adjacent horizontal strips. The outer dimensions between the strips are approximately the same, and the curvatures of the fixed portions 11e and 11e are approximately the same as the curvature of the circumferential surface of the vertical or horizontal strips. Both fixing portions 11e, 11e have a length that allows them to be fitted onto the circumferential surface of the vertical strip or the circumferential surface of the horizontal strip of the welded wire mesh within a range of slightly more than 1/4 in the circumferential direction of the circumferential surface. It is set as. Further, the tip surfaces ST, ST of both the fixing parts 11e, 11e have an angle α between the plane formed by the contact parts 11b, 11b of the main bodies 11a, 11a arranged in parallel and the parallel plane H. The slope is approximately 45°, so that the tip ends of the tip surfaces ST and ST engage with the circumferential surface of the vertical strip or the circumferential surface of the horizontal strip of the welded wire mesh.

The dimension between the first frame members 11, 11 arranged in parallel is shorter than the dimension between adjacent vertical strips or the dimension between adjacent horizontal strips that constitute the welded wire mesh to which the first fixture F1 is attached. The second frame members 12, 12 described above are respectively installed at both end portions of the main bodies 11a, 11a of the first frame members 11, 11. The length dimension of the second frame members 12, 12 is also shorter than the dimension between adjacent vertical strips or the dimension between adjacent horizontal strips constituting the welded wire mesh to which the first fixture F1 is attached, The dimension between the second frame members 12, 12, which are arranged opposite to each other, is similarly shorter than the dimension between adjacent vertical strip members or the dimension between adjacent horizontal strip members.

In addition, in the first fixture F1 shown in FIG. 8, a case is shown in which the second frame members 12, 12 are installed at both end portions of the main bodies 11a, 11a of both the first frame members 11, 11, respectively, but the present invention is not limited to this, and may be between the appropriate positions of the rising parts 11c, 11c of both the first frame members 11, 11, between the appropriate positions of the contact parts 11b, 11b of both the first frame members 11, 11, etc. It can be installed at various positions, such as between appropriate positions of one frame member 11, 11.

Approximately at the longitudinal center of the contact portions 11b, 11b of the first frame members 11, 11 described above, adjacent vertical strips of another welded wire mesh superimposed on the welded wire mesh to which the first fixture F1 is attached are located. Connecting means 14, 14 are provided, respectively, for connecting the members or adjacent horizontal members.

The coupling means 14 is constructed by providing a U-shaped notch on the central axis of a longitudinally long rectangular plate-shaped main body 14a extending from the ceiling position to a position near the bottom of the main body 14a. This notch serves as an insertion portion 14e into which the vertical strip or horizontal strip of the other welded wire mesh is inserted, and the portions on both sides of the insertion portion 14e of the main body 14a are inserted into the insertion portion 14e. A pair of holding portions 14b, 14b are provided to hold the inserted longitudinal or horizontal strip material.

An insertion opening 14c is provided on the ceiling side of the main body 14a of the insertion portion 14e for inserting another vertical or horizontal strip of welded wire mesh into the insertion portion 14e, and the above-mentioned holding portions 14b, 14b Beak-shaped first retaining portions 14d1, 14d1 are provided protruding from the portions facing the insertion opening 14c, respectively. That is, the width of the insertion port 14c between the first retaining parts 14d1, 14d1 is smaller than the width of the insertion part 14e, so that the vertical or horizontal material inserted into the insertion part 14e The material is prevented from slipping out from the insertion portion 14e. Further, the ceiling portions of the first retaining portions 14d1 and 14d1 are respectively tapered so that the height position from the bottom of the insertion portion 14e becomes lower toward the insertion opening 14c, so that the height of the other welded wire mesh is The strip or horizontal strip is guided to the insertion port 14c.

Further, at the edge portions of the holding portions 14b, 14b facing the insertion portion 14e, at a height position separated from the first retaining portions 14d1, 14d1 by an appropriate distance, there is provided a groove having approximately the same size as the first retaining portions 14d1, 14d1. Second retaining portions 14d2, 14d2 are provided in a protruding manner. Here, the height dimension from the bottom of the insertion part 14e to the second retaining parts 14d2, 14d2 is such that the welded wire mesh to which the first fixture F1 is attached and the other welded wire mesh overlapped with the welded wire mesh are first fixed. When fixed with the fixture F1, the circumferential surface of the vertical strip or horizontal strip of another welded wire mesh inserted into the insertion portion 14e is attached to the second retaining portions 14d2, 14d2 of the first fixture F1. It is set to the corresponding value.

In this way, the other longitudinal strips or horizontal strips of the welded wire mesh inserted into the insertion portion 14e pass through the second retaining portions 14d2, 14d2 and are inserted into the bottom side of the insertion portion 14e, and in that state. Since the circumferential surface of the vertical strip or horizontal strip comes into contact with the second retaining portions 14d2, 14d2, even if the worker works on another welded wire mesh, the insertion portion Since the vertical or horizontal strips inserted into the insertion portion 14e are prevented from wobbling, the work of the worker is not hindered, and the vertical or horizontal strips inserted into the insertion portion 14e are prevented from wobbling. The strip is further prevented from slipping out of the insertion portion 14e.

The aforementioned holding parts 14b, 14b are capable of bending in the direction of separating from each other, and a pressing force is applied to the longitudinal or horizontal strips of the other welded wire mesh guided to the insertion port 14c. As the holding parts 14b and 14b bend in the direction of separating from each other, the width of the insertion port 14c becomes relatively large, and the vertical or horizontal material passes through the insertion port 14c and enters the insertion part 14e. After that, the holding parts 14b and 14b return to their original positions, so the width of the insertion port 14c also returns to its original state, and the vertical or horizontal material inserted into the insertion part 14e This prevents them from escaping. This connects the longitudinal or horizontal strips to the coupling means 14.

On the other hand, the height from the abutting part 11b of the first frame member 11 to the ceiling position of the holding part 14b is greater than the height from the abutting part 11b to the ceiling position of the fixing part 11e of the first frame member 11. When the first fixture F1 is enlarged and fixed to a welded wire mesh, the holding portions 14b, 14b, 14b, 14b of the first fixture F1 protrude from the welded wire mesh.

As will be described later, since the first fixture F1 is fixed in advance to one welded wire mesh, the vertical or horizontal strips of another welded wire mesh may be connected to the coupling means 14, 14 of the first fixture F1. By connecting in this manner, the welded wire mesh and the other welded wire mesh superimposed thereon are fixed to each other.

By the way, when the surface to be constructed is a deck plate having a plurality of ridge-like unevenness, the dimension between the first frame members 11 and 11 arranged oppositely is less than 1/2 of the width of the mountain part of the deck plate. It is set to the value of When one of the pair of first frame members 11, 11 constituting the first fixture F1 is located on the shoulder of the peak of the deck plate, the first fixture F1 is superimposed on the welded wire mesh to which the first fixture F1 is attached, as described later. When trying to apply pressure to the other welded wire mesh and connect the vertical strips or horizontal strips of the other welded wire mesh to the coupling means 14, 14 of the first fixture F1, the peaks of the deck plate The first frame member 11 located at the shoulder of the deck plate sinks into the valley of the deck plate, causing warpage in the welded wire mesh and other welded wire meshes. On the other hand, if the dimension between the first frame members 11, 11 of the first fixture F1 is set to a value less than 1/2 of the width of the peak of the deck plate, both the first frame members 11, 11 is prevented from being located on the shoulder of the mountain portion of the deck plate, it is avoided that the welded wire mesh and other welded wire meshes are warped as described above.

The longitudinal strips or horizontal strips of the other welded wire mesh are guided to the outer parts of the above-mentioned holding parts 14b, 14b, that is, the parts of the holding parts 14b, 14b on the second frame members 12, 12 side, respectively. Triangular guide portions 14f, 14f are provided protrudingly. The ceiling side of the guide part 14f is tapered such that its height decreases as it becomes farther away from the holding part 14b, and the length of the guide part 14f is the same as that of the first frame member facing the guide part 14f. 11, the value is set so that the vertical strips or horizontal strips of the other welded wire mesh cannot enter.

As will be described later, when another welded wire mesh is superimposed on the welded wire mesh to which the first fixture F1 is attached, the vertical strips or horizontal strips of the other welded wire mesh overlap the first fixture F1. If it is not located on the holding parts 14b, 14b, 14b, 14b forming a However, at this time, if the holding parts 14b, 14b, 14b, 14b are not provided with the guide parts 14f, 14f, 14f, 14f, other welded wire meshes will move in parallel to the holding parts 14b, 14b, 14b, 14b, smooth parallel movement is obstructed. However, in the first fixture 1F according to the present invention, since the above-mentioned guide parts 14f, 14f, 14f, 14f are provided in the holding parts 14b, 14b, 14b, 14b, the longitudinal strips of other welded wire meshes are The material or horizontal strip material slides on the ceiling sides of the guide portions 14f, 14f, 14f, 14f, and other welded wire meshes can be smoothly moved in parallel.

Further, on the bottom side of both main bodies 14a, 14a, fixing pieces 14g, 14g, 14g, 14g for fixing to the corresponding first frame members 11, 11 are provided, for example, so as to form an L-shape when viewed from the side. By fixing one or more (two in FIG. 1) fixing pieces 14g, 14g, 14g, 14g to the corresponding first frame members 11, 11 by welding, gluing, etc. , both main bodies 14a, 14a are fixed inside the corresponding first frame members 11, 11.

The fixing piece 14g may have various shapes such as a plate shape or an arch shape, and one or more fixing pieces 14g may be provided on the main body 14a. Further, in this embodiment, a case is shown in which the main body 14a and the first frame member 11 are configured separately, but the present invention is not limited to this, and the main body and the first frame member are integrated by casting or the like. It may be configured as follows. Further, in this embodiment, a case has been described in which both main bodies 14a, 14a are fixed inside the corresponding first frame members 11, 11, but the present invention is not limited to this, and both main bodies 14a, 14a are fixed inside the corresponding first frame members 11, 11. It may be fixed on the first frame members 11,11 or on the outside of the corresponding first frame members 11,11.

By the way, the guide parts 14f, 14f, 14f, 14f protruding from the pair of holding parts 14b, 14b, 14b, 14b may be flush with the corresponding main bodies 14a, 14a, When the frame members 11, 11 are bent outward (see FIGS. 1 and 3) or inward, the above-mentioned fixing pieces 14g, 14g, 14g, 14g are fixed to the corresponding first frame members 11, 11 by spot welding. This is preferable because it is possible to avoid an accident in which the electrodes of the welding machine come into contact with the guide parts 14f, 14f, 14f, 14f when doing so.

In this embodiment, in order to fix the bodies 14a, 14a of the coupling means 14, 14 to the corresponding first frame members 11, 11, fixing pieces 14g, 14g, 14g, 14g are attached to the bodies 14a, 14a. Although the case where the protrusions are provided has been described, the present invention is not limited to this, and the first frame member 11 corresponding to the main bodies 14a, 14a of the coupling means 14, 14 is provided without providing the fixing pieces 14g, 14g, 14g, 14g. , 11 may be fixed by arc welding or the like. In this case, the guide portions 14f, 14f, 14f, 14f protruding from the paired holding portions 14b, 14b, 14b, 14b can be flush with the corresponding main bodies 14a, 14a.

On the other hand, in this embodiment, the first frame members 11, 11 and the second frame members 12, 12 are made of bar materials, but the present invention is not limited to this, and the first frame members and the second frame members The member may be made of a plate material.

On the other hand, FIG. 9 is a perspective view showing an example of the second fixture F2 mentioned above. Note that in FIG. 9, parts corresponding to those shown in FIG. 8 are given the same numbers and their explanations will be omitted.

As shown in FIG. 9, the main bodies 14a, 14a constituting the coupling means 14, 14 extend by an appropriate length toward the side opposite to the holding parts 14b, 14b, 14b, 14b of the first frame members 11, 11, respectively. Leg portions are formed at the base plate, and these leg portions function as second abutting portions 15, 15.

That is, in the second contact portion 15, both side edges of the legs extending from the first frame member 11 of the main body 14a are raised inwardly or outwardly (inwardly in FIG. 9), as viewed in plan. is formed into a substantially U-shape, which provides the required strength. Further, second fixing pieces 15g, 15g fixed to the first frame member 11 are protruded from the second contact portion 15 so as to face the fixing pieces 14g, 14g with the first frame member 11 in between. The second abutting portion 15 is fixed to the first frame 11 by fixing the second fixing pieces 15g to the first frame member 11 by welding, adhesive, or the like.

In such a second contact part 15, instead of the contact part 11b of the first frame member 11 described above, since the second contact part 15 contacts the construction target surface, the fixed part 11e, The welded wire mesh fixed at 11e, 11e, 11e and the other welded wire mesh connected to the coupling means 14, 14 can be supported at a predetermined height position spaced from the valley of the deck plate. The length of the second fixing pieces 15g, 15g is determined according to the depth of the valley DB of the deck plate DP shown in FIG. The height position of the welded wire mesh held by the second fixture F2 is made to be approximately the same as the height position of the welded wire mesh supported by the second fixture F2.

Note that the height of the rising portions 11c, 11c of the main body 11a of the first fixture F1 described above is approximately the same as the length of the second contact portion 15 provided on the second fixture F2, and the first The fixture may be located in the valley of the deck plate, but in the second fixture F2 described above, the portion of the second fixture F2 that corresponds to the first fixture F1 is located in the first fixture F2. Since it can be shared with F1, manufacturing costs can be reduced, which is preferable.

On the other hand, FIGS. 10 and 11 are perspective views showing examples of the first spacer SP1 and second spacer SP2 described above. The first spacer SP1 has substantially the same configuration as the first fixture F1 except that it does not include the coupling means 14, 14 shown in FIG. , 14 is not provided, it has substantially the same configuration as the second fixture F2.

That is, as shown in FIG. 10, the first spacer SP1 includes a pair of first frame members 11, 11 formed by molding rod-shaped members into an inverted convex shape, and a pair of short rod-shaped second frame members 12, 12. The first frame members 11, 11 are fixed in a parallel grid shape when viewed from above, and fixing portions 11e, 11e, 11e, 11e for fixing to the welded wire mesh are provided at both ends of the first frame members 11, 11, respectively.

The first frame member 11 has a main body (carrying part) 11a. At both ends of the main body 11a, short arm portions 11d, 11d extend in a direction substantially parallel to the contact portion 11b and away from each other, and the tip portions of both arm portions 11d, 11d The above-mentioned hook-shaped fixing parts 11e, 11e are formed by standing up in a posture parallel to the rising parts 11c, 11c and curving outward from each other.

The dimension between the inner bottoms of both fixing parts 11e and 11e provided on the first frame member 11 is the outer dimension between adjacent vertical strips that constitute the welded wire mesh to which the first fixture F1 is attached, or the dimension between adjacent horizontal strips. The outer dimensions between the strips are approximately the same, and the curvatures of the fixed portions 11e and 11e are approximately the same as the curvature of the circumferential surface of the vertical or horizontal strips. Both fixing portions 11e, 11e have a length that allows them to be fitted onto the circumferential surface of the vertical strip or the circumferential surface of the horizontal strip of the welded wire mesh within a range of slightly more than 1/4 in the circumferential direction of the circumferential surface. It is set as. Further, the tip surfaces ST, ST of both the fixing parts 11e, 11e have an angle α between the plane formed by the contact parts 11b, 11b of the main bodies 11a, 11a arranged in parallel and the parallel plane H. The slope is approximately 45°, so that the tip ends of the tip surfaces ST and ST engage with the circumferential surface of the vertical strip or the circumferential surface of the horizontal strip of the welded wire mesh.

The dimension between the first frame members 11, 11 arranged in parallel is shorter than the dimension between adjacent vertical strips or the dimension between adjacent horizontal strips that constitute the welded wire mesh to which the first fixture F1 is attached. The second frame members 12, 12 described above are respectively installed at both end portions of the main bodies 11a, 11a of the first frame members 11, 11. The length dimension of the second frame members 12, 12 is also shorter than the dimension between adjacent vertical strips or the dimension between adjacent horizontal strips constituting the welded wire mesh to which the first fixture F1 is attached, The dimension between the second frame members 12, 12, which are arranged opposite to each other, is similarly shorter than the dimension between adjacent vertical strip members or the dimension between adjacent horizontal strip members.

In such a first spacer SP1, similarly to the first fixture F1 described above, the spacer is fixed to a welded wire mesh, and the welded wire mesh is placed at a predetermined position on the deck plate so that the spacer is located at the peak of the deck plate. The welded wire mesh is held by a spacer at a position separated from the crest of the deck plate by a predetermined height.

On the other hand, as shown in FIG. 11, the second spacer SP2 is located midway in the longitudinal direction of the abutment portions 11b, 11b of the first frame members 11, 11, substantially similar to the second fixture F2 of FIG. , leg-shaped second abutting parts 35, 35 are formed by hanging a plate material having a substantially U-shape in plan view by an appropriate length, and the length dimension of the second abutting part 35 is as follows. It is determined according to the depth dimension of the valley portion DB (see FIG. 3) of the deck plate DP mentioned above.

Then, as shown in FIG. 2, the direction in which the first fixture F1, second fixture F2, first spacer SP1, and second spacer SP2 are attached to the welded wire meshes WM, WM, ... is determined as follows. (Step S15).

That is, as shown in FIGS. 5 and 6, in the first fixture F1 or the second fixture F2, in the overlapping region of the welded wire meshes WM, WM, ... arranged side by side in the horizontal direction, The pair of first frame members 11, 11 are set in a posture parallel to the horizontal strips W2, W2, . . . of the welded wire mesh WM. As a result, it is possible to prevent the welded metal meshes WM, WM, . On the other hand, in the overlapping region of the welded wire meshes WM, WM, ... arranged adjacent to each other in the longitudinal direction, the paired first frame members 11, 11 are connected to the vertical strip members W1, W1, ... of the welded wire mesh WM. Set in a parallel position. This can prevent the welded wire meshes WM, WM, . . . , which are arranged adjacent to each other in the vertical direction, from shifting in the vertical direction.

As described above, the overlapping portion of the four welded wire meshes WM, WM, WM, WM adjacent to each other in the horizontal and vertical directions is surrounded by the first fixture F1 and/or the second fixture F2. It has become. The welded wire meshes WM, WM placed next to each other in the horizontal direction are prevented from shifting in the horizontal direction by the first fixture F1 or the second fixture F2, and are also placed next to each other in the vertical direction. The welded wire meshes WM, WM arranged in the same manner are prevented from shifting in the vertical direction by the first fixture F1 or the second fixture F2. In this case, displacement in both the vertical and horizontal directions is prevented.

On the other hand, in the first spacer SP2 and the second spacer SP2, the paired first frame members 31a, 31a are set in a posture parallel to the longitudinal direction of the deck plate DP shown in FIG.

In this way, when the positions and directions for attaching the first fixture F1, second fixture F2, first spacer SP1 and/or second spacer SP2 to the welded wire mesh WM, WM, ... are determined, the installer Based on the construction drawings shown in , if the arrangement is at the peak of the deck plate, select the first fixtures F1, F1,... or the first spacers SP1, SP1,..., and if the arrangement is at the peak of the deck plate. , the second fixtures F2, F2, . . . or the second spacers SP2, SP2, . . . are selected (step S16), and a construction design drawing to be executed is obtained (step S17).

When the construction design process is completed in this way, as shown in Figure 1, the builder performs processing to form the required number of welded wire meshes into the shape designed in the construction design process (step S3). For each welded wire mesh, a first fixture, a second fixture, a first spacer, and/or a second spacer were designed in the construction design process on the front and back of the welded wire mesh, and at each position of the welded wire mesh determined in the construction design process. direction (step S5). In addition, the forming of each welded wire mesh and the attachment of the first fixture, second fixture, first spacer, and/or second spacer to each formed welded wire mesh are performed at the factory that manufactures the welded wire mesh. Although this method is highly efficient and suitable, it may also be performed at the construction site.

In this way, when each welded wire mesh is formed and the first fixture, the second fixture, the first spacer, and/or the second spacer are attached, the constructor can perform all welding on the surface to be constructed. It is determined whether the placement of the wire mesh has been completed (step S6), and if the placement of all the welded wire mesh has not been completed, the corresponding (step S7), and in the overlapping region with adjacent welded wire meshes, the vertical strips and/or horizontal strips of the welded wire meshes are positioned above the first fixture and/or the second fixture. Applying pressure to the connecting means of the first fixture and/or the second fixture to connect the vertical strips and/or the horizontal strips of the welded wire mesh, thereby fixing both the overlapping welded wire meshes to each other ( Step S8). Then, the builder repeats the operations from step S6 to step S8 until it is determined in step S6 that all the welded wire meshes have been placed on the construction target surface. As a result, even inexperienced installers and workers can reliably install a plurality of welded wire meshes in a short time without forcing the installers and workers to perform heavy labor.

Note that it is preferable that the above-described pressure is applied to the vertical strips and/or the horizontal strips of the welded wire mesh by stepping on the vertical strips or the horizontal strips with the feet of the builder. That is, for example, two constructors hold a piece of welded wire mesh between them and place the welded wire mesh in the position specified in the construction drawings so that the edge of the welded wire mesh touches one or more previously placed welded wire meshes. After arranging the first fixture and/or the second fixture, the longitudinal and/or horizontal strips of the welded wire mesh located on the first fixture and/or the second fixture are stepped on, and the coupling means and/or The longitudinal and/or horizontal strips of the welded wire mesh are coupled to the coupling means of the second fixture. This allows the placement of a new welded wire mesh and the fixing of the previously placed welded wire mesh to the new welded wire mesh in one operation, making work efficiency as high as possible. be able to.

Here, the dimension between both first frame members 11, 11 arranged in parallel is the dimension between adjacent longitudinal members configuring the welded wire mesh to which the third fixture F3 is attached, or the dimension between adjacent horizontal members The two second frame members 12, 12 described above are the peripheral surfaces of the arm portions 11d, 11d, 11d, 11d of the two first frame members 11, 11, and are opposite to the fixed portion 11e. They are erected in their respective positions. The length dimension of the second frame members 12, 12 is also shorter than the dimension between adjacent longitudinal members or the dimension between adjacent horizontal members constituting the welded wire mesh to which the third fixture F3 is attached, The dimension between the second frame members 12, 12, which are arranged opposite to each other, is similarly shorter than the dimension between adjacent vertical strip members or the dimension between adjacent horizontal strip members.

Inside each of the first frame members 11, 11, adjacent vertical strip members or adjacent horizontal strip members of another welded wire mesh superimposed on the welded wire mesh to which the third fixture F3 is attached are connected. A pair of second coupling means 20, 20 are provided. The second coupling means 20 includes second main bodies 21a, 21a made of a bar formed into an inverted trapezoid shape and having a spring force. The bottom portion 21b of the second body 20a is arranged substantially parallel to the contact portion 11b of the first frame member 11, and is fixed to the contact portion 11b by welding, adhesive, or the like. On the other hand, both leg portions 21c, 21c of the second main body 20a rising from both ends of the bottom portion 21b pass between the aforementioned second frame members 12, 12, and are connected to the fixed portions 11e, 11e of the first frame member 11. A second fixing part 21e extends to a high position and engages and fixes adjacent vertical strips or adjacent horizontal strips of another welded wire mesh at the ends of both leg sides 21c, 21c, respectively. , 21e are provided.

The fixing portions 11e, 11e of the first frame member 11 are curved toward the inside of the U-shaped main body 11a of the first frame member 11 while facing each other. The fixing portions 21e, 21e are curved toward the outside of the second main body 21a so as to be spaced apart from each other. The curvature of the fixing parts 11e, 11e of the first frame member 11 and the curvature of the second fixing parts 21e, 21e of the second coupling means 20 are determined by the vertical strips W1 or the horizontal strips W2 (FIG. 17, etc.) of the welded wire mesh WM described above. The fixed portions 11e, 11e and the second fixed portions 21e, 21e have approximately the same value as the curvature of the circumferential surface of the welded wire mesh WM. , the length is such that it can be fitted over a little more than 1/4 of the circumferential surface.

Further, the tip surfaces ST, ST of the fixing parts 11e, 11e and the tip surfaces ST2, ST2 of the second fixing parts 21e, 21e are formed by both contact parts 11b, 11b of the main bodies 11a, 11a arranged in parallel. The angle α between the plane and the parallel plane H is approximately 45° for the former, and approximately 135° for the latter, so that the tip surfaces ST, ST have their tips aligned with the third fixture. The welded wire mesh WM to which F3 is attached engages with the circumferential surface of the vertical strip member W1 or the circumferential surface of the horizontal strip member W2, while the tip ends of the tip surfaces ST2 and ST2 are the welded wire mesh to which the third fixture F3 is attached. It is adapted to engage with the circumferential surface of the vertical strip material W1 or the circumferential surface of the horizontal strip material W2 of another welded wire mesh WM superimposed on WM.

FIG. 25 is for explaining an example of a state in which the welded wire mesh to which the third fixture shown in FIG. 24 is attached and another welded wire mesh superimposed on the welded wire mesh are connected and fixed by the third fixture. FIG. 2 is a partially omitted perspective view of FIG. Note that in FIG. 25, parts corresponding to those shown in FIG. 24 are given the same numbers. In addition, in this example, the lower welded wire mesh WM and the upper welded wire mesh WM are both in the front state, and the upper welded wire mesh WM is placed on the lower welded wire mesh WM, and the squares M, M are overlapped, that is, the positions of the squares M and M of both are overlapped so that they match vertically. Note that in both the lower welded wire mesh WM and the upper welded wire mesh WM, one of the adjacent horizontal stripes W2 constituting the square mesh M, M is omitted.

As shown in FIG. 25, the third fixture F3 is attached to the lower welded wire mesh WM. That is, the main bodies 11a, 11a and the second main bodies 21a, 21a of the third fixture F3 are disposed within the square mesh M of the lower welded wire mesh WM, and the adjacent longitudinal members forming the square mesh M Fit the fixing parts 11e, 11e, 11e, 11e of the third fixture F3 onto W1, W1 from the outside to the inside of the square mesh M, and fix the third fixture F3 to the lower welded wire mesh WM. It has been done.

In this state, when the upper welded wire mesh WM is superimposed on the lower welded wire mesh WM so that the squares M and M of both overlap, the adjacent welded wire meshes constituting the corresponding squares M of the upper welded wire mesh WM are The peripheral surfaces of the vertical strips W1, W1 are placed on the tip surfaces ST2, ST2, ST2, ST2 of the second fixing parts 21e, 21e, 21e, 21e constituting the second coupling means 20, 20 of the third fixture F3. Therefore, by applying pressure to the upper welded wire mesh WM, the second fixing parts 21e, 21e, 21e, 21e are attached to the vertical strips W1, W1 and/or the horizontal strips W2 (W2). It is fitted outward from the inside of the eye M towards the outside. In this way, the upper welded wire mesh WM is coupled to the second coupling means 20, 20, and the lower welded wire mesh WM and the upper welded wire mesh WM are fixed with one touch by the third fixture F3. As a result, even inexperienced installers and workers can reliably install a plurality of welded wire meshes in a short time without forcing the installers and workers to perform heavy labor.

In addition, the application of pressure to the vertical strips W1, W1 and/or the horizontal strips W2 (W2) of the upper welded wire mesh WM is carried out by stepping on the vertical strips or the horizontal strips with the feet of the builder. Then, it is suitable. Similar to the first fixture F1 and the second fixture F2 described above, for example, two constructors hold a piece of welded wire mesh WM and place the welded wire mesh WM in the position specified in the construction blueprint. After overlapping the edges of the previously placed one or more welded wire meshes WM so that the meshes M and M of each welded wire mesh WM and WM overlap, welding is performed on the third fixture F3. The vertical strips W1, W1 and/or the horizontal strips W2 (W2) of the wire mesh WM are stepped on, and the longitudinal strips W1, W1 and/or the welded wire mesh WM are attached to the second coupling means 20, 20 of the third fixture F3. Alternatively, the horizontal strip members W2 (W2) are combined. This allows the placement of a new welded wire mesh and the fixing of the previously placed welded wire mesh to the new welded wire mesh in one operation, making work efficiency as high as possible. be able to.

On the other hand, the leg sides 21c, 21c constituting the second coupling means 20 are able to bend in the direction toward each other, and are placed on the tip surfaces ST2, ST2 of the second coupling means 20. When a pressing force is applied to the vertical strips W1, W1 of the upper welded wire mesh WM, the leg portions 21c, 21c of the second coupling means 20 are bent in the direction toward each other, so that the vertical strips W1, W1 of the upper welded wire mesh WM are bent. Since the strips W1, W1 pass through the second fixing parts 21e, 21e of the second coupling means 20, and then both leg sides 21c, 21c return to their original positions, the vertical strips W1 of the upper welded wire mesh WM , W1, the second fixing portions 21e, 21e are fitted outwardly from the inside of the square mesh M toward the outside.

Further, the dimension between the two second coupling means 20, 20 is set to be slightly larger than twice the outer diameter of the vertical strip material W1 or the horizontal strip material W2 constituting the welded wire mesh WM, and as will be described later, Two vertical strips W1, W1 or two horizontal strips W2, W2 can be inserted between the two second coupling means 20, 20.

It has substantially the same configuration as the third fixture F3. That is, the leg sides 21c, 21c constituting the second coupling means 20 of the fourth fixture F4 pass between the second frame members 12, 12 and connect to the fixing parts 11e, 11e of the first frame member 11, as before.
