Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of an embedded mold for forming a legal frame.
[0002]
[Prior art]
As a method of reinforcing the slopes of the hillside and other slopes such as roads and construction sites, a mesh body such as a wire mesh is laid on the slope, and an embedded formwork for forming the frame is placed on this mesh body. Then, there is a construction method in which mortar or concrete (hereinafter referred to as mortar) is sprayed so as to fill the formwork, and a grid-like methodwork is constructed on the slope.
[0003]
As shown in FIG. 9, as the above-mentioned embedded formwork for forming a normal frame, a connecting spacer disposed between parallel side-faced formframes is provided between two horizontal wires and the wires. Is composed of two longitudinal wires connected to each other, and both ends of the horizontal wire are pivotally connected to the side mold frame around the longitudinal axis so as to be foldable. is there.
[0004]
The above-mentioned embedded mold for forming a frame is carried into the frame construction site in a folded state so that two side molds are overlapped. It is used to form a normal frame by placing the upper and lower main bars in a formwork, supported by horizontal wires, and blowing mortar into and out of the formwork.
[0005]
[Problems to be solved by the invention]
However, in the conventional embedded mold for forming a frame, since the net-shaped side mold and the connecting spacer are directly connected, the side mold becomes an obstacle to work from the side, and the bottom main reinforcement The work of binding the lower wire rod of the connecting spacer and the work of bundling the stirrup and the lower main bar when wrapping the stirrup (helper bar) around the upper main bar and the lower main bar are very troublesome and workable. There was a problem of being bad.
[0006]
In addition, since the mortar spraying operation is restricted from above and from above and below, it is easy for mortar to spray poorly on the back side of the intersection between the spacer and the upper and lower main bars. Furthermore, it is difficult to spray the mortar so as to avoid the spacers and main bars, and when the mortar is sprayed on the spacers and main bars, a part of the mortar rebounds and granulates. By bonding to each other, there is a concern that the mortar is likely to be in a porous state, and the strength of the frame is reduced.
[0007]
The present invention has been made in view of the above-described problems of the prior art, and in the embedded mold for forming a method frame provided with a connecting spacer made of a wire, all the use of a net-like body as a side mold is performed. Or most of the work can be omitted, and work from the side, for example, work to bind the bottom main bar to the lower wire of the connecting spacer, or wrap the stirrup around the upper and lower main bars It is an object of the present invention to make it possible to easily perform the work of binding the stirrup and the bottom main bar, the work of filling mortar into the mold, and the like.
[0008]
[Means for Solving the Problems]
In order to solve the above problem, the present invention takes the following technical means. That is, according to the first aspect of the present invention, a plurality of connecting spacers are rotatably connected to a pair of side frames formed in a substantially rectangular shape by a plurality of wires, and are foldable and self-supporting when deployed. A possible frame is constructed, and a movable frame material that can move in the horizontal direction or the vertical direction is attached to the side frame to constitute a method frame forming embedded mold frame. Here, the so-called “substantially rectangular shape” refers to a shape in which a portion that partially protrudes from the rectangle, such as a shape combining well shapes, as well as a rectangle.
[0009]
The embedded frame for forming a frame with the above configuration can be carried into the frame frame construction site in a folded state so that the side frames of the frame are overlapped. It can be installed at a predetermined position and can stand on its own.
[0010]
In addition, since a low slump mortar is used, if there is a framework to a certain extent, for example, about 5 cm to 10 cm, the mortar will not flow out of the mold, and when mortar is sprayed, For this reason, if it is a gentle gradient, the embedded frame for forming the frame can be configured with only the framework without using a net.
[0011]
In particular, since the moving wire attached to the side frame of the frame is movable in the horizontal direction or the vertical direction, by sliding a part of the side frame, the side of the mold frame is opened to release from the side of the mold frame. A working space can be formed.
[0012]
Therefore, various work from the side, for example, the work of bundling the lower main bar to the lower part of the connecting spacer, or the star wrap and the lower main bar when binding the upper and lower main bars with a stirrup (helper bar) wrapped It is possible to easily perform the work to be performed.
[0013]
In addition, after the mortar is filled, when the mortar portion adhering to the outside of the mold is reshaped, it can be easily reshaped by sliding the moving wire.
[0014]
In addition, when mortar is sprayed inside and outside the mold, filling may occur in the back side in the spraying direction, such as the back side of the main reinforcement, and cavities (sparse parts such as mortar and concrete) may be formed. However, as mentioned above, since the mold is composed of only the framework without using the reticulated side mold, the mortar can be sprayed into the mold from the side of the mold as needed. In addition, it is possible to avoid filling defects on the back side in the blowing direction such as the back side of the main bar, and the quality of the method frame can be improved also from this aspect.
[0015]
In the invention described in claim 2, a plurality of connecting spacers are rotatably connected to a pair of side frames formed in a substantially rectangular shape by a plurality of wires, and can be folded and self-supported when deployed. A connecting member that constitutes a framework and has a moving wire that can move in the horizontal direction or the vertical direction attached to the side frame, and that can move simultaneously on the same side and in the same moving direction. Thus, a plurality of frames are connected to form an embedded mold for forming a frame.
[0016]
According to the above configuration, when sliding the moving wire rod, such as performing various operations from the side, the side frame can be opened and closed by sliding a plurality of moving wire rods in one operation, which is efficient. is there.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 4 show an example of an embedded mold for forming a legal frame according to the present invention. The embedded frame for forming a normal frame is composed of a skeleton 1 made of a wire material (for example, a steel wire material or a soft iron wire material) that can be folded and can stand up when deployed.
[0018]
The skeleton 1 includes a plurality (four in the illustrated example) of horizontal wires 2a, 2b, 2c, and 2d arranged in parallel, and a plurality (four in the illustrated example) connected to each other by means such as welding. A plurality of (four in the illustrated example) connecting spacers 5 made of a wire rod are pivotally connected to a pair of side surface frames 4 formed in a rectangular shape by the vertical wire rods 3a, 3b, 3c, and 3d. Further, the movable wire 6 is bent and bent at both ends so as to be substantially ring-shaped or bowl-shaped, and is movably mounted on the horizontal wires 2a and 2d.
[0019]
The connecting spacer 5 includes two wire rods 7a and 7b that intersect in an X shape within a plane perpendicular to the side frame 4 in a state where the embedded frame for forming the frame is expanded to the use posture, and both wire rods 7a. , 7b and the transverse wires 8a and 8b connected to the upper and lower portions by means of welding or the like, and ring-shaped portions are bent and formed at both ends of each wire 7a, 7b, 8a, 8b. The ring-shaped portion is pivotally attached to the vertical wires 3a, 3b, 3c, 3d of the side frame 4 so as to be rotatable around the vertical axis, and the pair of side frames 4 can be switched between a self-supporting posture and a folded posture, The connecting spacer 5 may be formed in a similar shape using a plate material or a plastic molded product.
The shape of the spacer is not limited to the above, and can be selected as appropriate, such as a well shape or a gate shape.
[0020]
According to said structure, as shown in FIG. 3, it can carry in to the frame construction site in the state which folded the frame 1 and expands the frame 1 to a use attitude | position in the field, and becomes independent at the predetermined position of a slope. And can be placed on the slope as an embedded mold for forming a frame.
[0021]
Then, for example, as shown in FIG. 4A, the upper main bars 10a and the lower main bars 10b are arranged in a state where they are supported by the necessary number of wires 8a and 8b of the connecting spacer 5, and these main bars 10a, The stirrup 11 is wound and fixed on 10b, and then a low slump mortar 13 is sprayed in and out of the embedded mold for forming the frame to form the frame.
[0022]
In this case, in the above-described embedded frame for forming a frame, the moving wire 6 attached to the side frame 4 can be slid, so that various operations from the side, for example, the lower end main reinforcement 10b is applied to the lower wire 8b. The work of bundling, the work of bundling the stirrup 11 and the bottom main bar 10b, etc. can be easily performed.
[0023]
In particular, according to the above-described configuration, the connecting spacer 5 has a bracing structure in which the two wire rods 7a and 7b intersect each other in the X shape, so that it is very robust and hardly deforms in the width direction. Therefore, when forming the normal frame portion along the contour line, the weight of the main muscles 10a and 10b supported by the connecting spacer 5, especially the operator steps on the main muscles 10a and 10b, or hits other objects against the main muscles 10a and 10b. There is no possibility that the mold will be deformed in the width direction due to an unexpected load at the time of contact, and the quality of the method frame can be improved.
[0024]
Moreover, when the mortar 13 is sprayed and filled in and out of the mold, there may be a filling failure portion on the back side in the spraying direction such as the back side of the main bars 10a and 10b. Further, the connecting spacer 5 is attached to the side frame 4. If it is composed of two wire rods 7a and 7b intersecting in an X shape within a plane perpendicular to each other, and horizontal wire rods 8a and 8b laid horizontally at two upper and lower portions of both wire rods 7a and 7b, When filling the mold with mortar 13 from one end in the longitudinal direction, cavities (sparse parts such as mortar and concrete) can be formed due to poor filling of the connecting spacer 5 to the back side of the X-shaped intersection. However, as mentioned above, the formwork is composed of a frame without using a reticulated side formwork, and the side face of the formwork is widely open. The frame can be filled with mortar 13, 10a, the back side of 10b or the like, the back or spraying direction, defective filling of the rear side of the X-shaped cross section of the connecting spacers 5 can be avoided, can improve the quality of legal frame from this plane.
[0025]
Further, after shaping the mortar 13 part that is attached to the outside of the mold after the mortar 13 is sprayed, the side surfaces can be leveled easily by sliding the moving wire 6.
[0026]
An example of the legal frame construction procedure is described as follows. First, as shown in FIG. 5A, after laying the wire mesh 12 on the slope, the bottom main bar 10b is installed on the wire mesh 12 in a state of being inserted into the stirrup 11 in advance, and the frame is placed on it. After the formation of the forming embedded frame 1, the lower principal bar 10 b is bound to the wire 8 b of the connecting spacer 5 with a wire or the like (not shown) as shown in FIG.
[0027]
Thereafter, as shown in FIG. 5 (C), the star wrap 11 is lifted, and the upper end main reinforcement 10a is placed in the stir wrap 11 on the wire 8a of the connecting spacer 5 and is connected with a wire or the like (not shown). After being bound, the stirrup 11 is bound to the upper main bar 10a and the lower main bar 10b with a wire or the like (not shown), and the bar arrangement work is completed as shown in FIG.
[0028]
In this case, since the side surface of the movable wire 6 is slid to open the side surface of the formwork, a hand can be inserted, and the upper end main bar 10a and the lower end main bar 10b can be bound to the wires 8a and 8b of the connecting spacer 5 The bundling operation of the stirrup 11 with respect to the upper main bar 10a and the lower main bar 10b can be easily performed.
[0029]
At this time, as shown in FIG. 2B, if the moving wire 6 on the same side is connected by a connecting member 17 made of a wire, a plurality of places can be opened and closed at one time. The movable wire rods 6 and 6 can be slid stably, which is also effective from the viewpoint of efficiency.
[0030]
Then, the moving wire 6 on the side frame 4 of the skeleton 1 is slid and placed at a predetermined position. As shown in FIG. 6B, the low slump mortar is placed inside and outside the embedded frame for forming the frame. 13 is sprayed to fill the mold.
[0031]
In this case, as shown in FIG. 6 (B), the skeleton 13 is used without using the reticulated side mold, so the mortar 13 can be sprayed from the side into the mold and the back side of the main bars 10a and 10b. Thus, it is possible to avoid poor filling of the back side in the spraying direction and the back side of the X-shaped intersection of the connecting spacer 5.
[0032]
After that, if there is 13 parts of mortar that has adhered too much outside the mold, the moving wire 6 is slid to smooth out the excess portion of the mortar 13, and if necessary, by applying a surface cosmetic blow and / or a trowel finish, Build the desired legal framework.
[0033]
In addition, as shown in FIG. 4, when there exists a part (for example, the lower part of a horizontal beam at the time of constructing a normal frame in a steep slope) where the dripping of the mortar is predicted by a gradient or the like, the side frame network 14 is appropriately attached Preferably, the side frame network 14 is provided with a plurality of hooks 9 that can be engaged and disengaged with the horizontal wires 2a, 2b, and 2c of the side frames 4 in the frame 1 by means of welding or the like. By engaging the hook 9 with the horizontal wires 2a, 2b, 2c, it can be detachably attached to the lower side frame 4.
[0034]
FIG. 7 and FIG. 8 show a method frame constructed by the above procedure. In the figure, reference numeral 15 denotes a vegetation base material sprayed in a thick layer on the wire mesh 12 between the frame frames, and 16 denotes an anchor. In addition, as shown in FIG. 7, the frame 1, the upper main muscle 10a, the lower main muscle 10b, the stirrup 11 and, if necessary, the side frame 14 are pre-assembled on a flat ground, and this is set on the slope. It can also be hung up to the installation position.
[0035]
【The invention's effect】
As described above, according to the present invention, in the embedded mold for forming a frame, it is only necessary to serve as a guide for spraying mortar, so that the use of most side mold frames can be omitted. A significant cost reduction can be achieved.
[0036]
In addition, since a part of the frame that forms the mold can be moved, the workability of reinforcement and binding is improved, and from above and from above and below without being disturbed by the net-like side mold. Mortar can be sprayed from the side and the side at the same time, so it is possible to avoid poor mortar spraying and porous mortar construction, which ensures the improvement of the strength of the legal frame. To be achieved.
