Hereinafter, a manufacturing method and a manufacturing system of a square block according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 3, in the method for manufacturing a rectangular block according to the present embodiment, a large number of rectangular blocks 1, 1,..., Such as marine blocks used for artificial reefs, are provided in a predetermined site. A large number of rectangular blocks 5 are placed in a manufacturing yard 2 having a predetermined square shape by arranging a large number of mold blocks 5 (form member shown in FIG. 3 and repeatedly placing concrete (hydraulic material). 3 omits a part of the rectangular block 1 and the formwork block 5 in order to make it easier to see, and the vertical and horizontal directions of FIG. The numerical value (1-14) has shown the quantity of the square block 1 arrange | positioned in the sequence direction (horizontal direction X, vertical direction Y).

  As shown in FIG. 4, the manufactured square block 1 is made of, for example, 1 m square cubic concrete (hydraulic material), and a hanging jig 11 is embedded in the upper portion 1a at the time of placing. And the concrete for forming the square block 1 is set to the consistency of 5-12 cm slump.

  In addition, as a hydraulic material which forms the square block 1, it is not limited to the said concrete, For example, steelmaking slag 60-70 vol%, blast furnace cement or blast furnace slag fine powder 10-20 vol%, water 10 Although it may be a mixture of ˜20 vol%, in this embodiment, the concrete of the above slump is targeted.

  The hanging jig 11 is a U-shaped reinforcing bar member (see FIG. 7C), and a U-shaped curved portion (hook portion 11 a) is formed at the central portion of the upper portion 1 a of the rectangular block 1. The suspension hook protrudes from the concave portion 1b on the spherical surface. The hook portion 11a is provided so as not to protrude from the height of the upper surface of the rectangular block 1.

As shown in FIGS. 1 and 3, the manufacturing yard 2 may be arranged with a plurality of (14 in this embodiment) rectangular blocks 1, 1,... In the vertical direction Y and the horizontal direction X in plan view. The base is made of, for example, concrete having a possible width, and the upper surface 2a of the base is formed flush with high accuracy.
In addition, on the four sides of the outer periphery of the manufacturing yard 2, a set of a fixed mold wall 3 constructed on two orthogonal sides of the manufacturing yard and the other two sides facing the fixed mold wall 3 of the manufacturing yard 2 is set. And a movable wall 4 disposed at the position.

  The fixed-type wall 3 is made of, for example, concrete, wood, steel, etc., and is provided in an L shape on the two sides constituting the corner corners of the outer periphery of the manufacturing yard 2 that forms a square as described above. , Fixed to the base of the manufacturing yard 2. The fixed-type wall 3 has a structure capable of withstanding the concrete filling pressure of a large number of rectangular blocks 1 placed in the production yard 2 and may be fixed to the base so that its position does not move. For example, when the fixed-type wall 3 is made of concrete, it is not particularly necessary to fix it by fixing means unless it moves by its own weight, and it is fixed to the base of the manufacturing yard 2 by fixing means such as anchors and bolts. Also good.

  The fixed-type wall 3 is accurately provided at a position equal to or higher than that of the rectangular block 1, and a member having good releasability such as an iron plate is disposed on the inner surface 3a side (side facing the manufacturing yard 2). doing. For example, when the fixed wall 3 is made of concrete, an iron plate can be attached to the inner surface 3a of the concrete. The fixed mold wall 3 may be integrally formed by assembling a formwork into the L-shaped whole and placing concrete, or a block-shaped single mold body may be formed as the L-shape. You may arrange | position and arrange | position so that it may become a shape.

  The movable wall 4 can move the concrete single block 4A having a predetermined shape to the set positions on the other two sides of the outer periphery of the placement region R where the fixed wall 3 is not disposed. It is provided in an L shape in a state. However, since it is necessary to be able to withstand the concrete filling pressure during the placement of the square block 1, it has a predetermined weight or is temporarily fixed at the time of placement. That is, the movable wall 4 only needs to be able to repeatedly move between a predetermined placement position (the set position) and a non-set position for each placement of the rectangular block 1 in the manufacturing yard 2. The single blocks 4A and 4A may be detachably fixed to the base.

  As shown in FIG. 1, the single block 4A has a rectangular shape in a plan view, and one side in the long side direction has a size corresponding to two of the square blocks 1, and the long side direction corresponds to the manufacturing yard 2. It is arranged toward the outer peripheral direction. The single block 4A is provided with a height equal to or higher than that of the rectangular block 1, and a member having good releasability such as an iron plate is disposed on the inner surface 4a side (side facing the placement region R). Has been established.

Next, a manufacturing method according to the present embodiment of the above-described rectangular block will be described based on a construction procedure.
First, as shown in FIG. 1 and FIG. 3, a manufacturing yard 2 is formed which can be formed into a flat surface within a site and can arrange a plurality of rectangular blocks 1 in the vertical direction Y and the horizontal direction X, respectively. The fixed wall 3 is constructed on two orthogonal sides of the yard 2.
Since the upper surface of the manufacturing yard 2 and the fixed mold wall 3 serve as reference positions in the vertical and horizontal directions for manufacturing the rectangular block 1 to be placed, they are manufactured with high accuracy.

  Next, as shown in FIG. 5, the form block 5 (form form member) for alternately forming the placement region R of the square block 1 in both the vertical direction Y and the horizontal direction X of the square block 1 is formed. Arrange in the production yard 2. That is, in FIG. 5, a white portion is an area where the formwork blocks 5 are arranged, and an area (colored area) surrounded by the formwork blocks 5 is the placement area R. In the present embodiment, the placement area R at this time is referred to as a first placement area R1. In addition, the location where the formwork block 5 which is not the said 1st placement area | region R1 is arrange | positioned becomes the 2nd placement location (2nd placement area | region R2 shown in FIG. 7) mentioned later.

  At this time, since the movable wall 4 shown in FIG. 4 is not installed, the set position (the other two sides of the manufacturing yard 2) where the movable wall 4 can be installed forms a free surface. In this open part, the worker can move freely. Therefore, an efficient installation work can be performed by arranging the formwork blocks 5 sequentially from the corners of the fixed mold wall 3.

  Here, as the form block 5, a concrete block manufactured to the same size as the product size of the rectangular block 1 is used.

  Next, as shown in FIG. 6, the movable wall 4 is arranged at the set positions of the other two sides facing the fixed wall 3 of the manufacturing yard 2. The release agent (see FIG. 2) is formed on the side surfaces of the plurality of mold blocks 5, 5,..., The inner surface 3a of the fixed mold wall 3, the inner surface 4a of the movable mold wall 4, and the upper surface 2a of the manufacturing yard 2. After applying the hydrophobic emulsion, concrete is cast to a plurality of first placement regions R1, R1,... To a predetermined height.

  At the time of placing the concrete, the hemispherical halved frame 6 and the hanging jig 11 shown in FIGS. 7A to 7C are embedded in the upper portion 1a (see FIG. 4) of the square block 1. That is, the half frame 6 is arranged in the upper central part after placement so as not to protrude upward from the height of the upper surface with the concave surface 6a facing upward. A pair of holes 6b are provided in the joint surface of the half frame 6 so that the embedded portion 11b of the hanging jig 11 can be inserted. The embedding portion 11b is inserted into the hole 6b of the half frame 6 arranged on the concrete, and the hanging jig 11 is set so that the U-shaped hook portion 11a is positioned on the concave surface 6a side. When the concrete has hardened to a predetermined strength, the half frame 6 is removed from the concrete, and the hanging jig 11 is left in the concrete, so that only the hanging jig 11 is attached to the upper portion 1a of the rectangular block 1. be able to. By arranging the upper end position of the hook portion 11a so as not to protrude upward from the height of the upper surface of the rectangular block 1, it is possible to manufacture the rectangular block 1 having no projecting portion. Can be stacked.

Next, as shown in FIG. 8, when the concrete is cured and demolding is possible, the movable mold wall 4 is moved outward from the manufacturing yard 2 from a predetermined set position, and then a plurality of molds are moved. The frame block 5 is taken out from the production yard 2.
At this time, by moving the movable wall body 4 in advance and forming a free surface on the outer peripheral portion of the manufacturing yard 2, a rectangular block placed in the manufacturing yard 2 (this is referred to as a first rectangular block 1A). ) And the formwork block 5 are eliminated and loosening occurs, so that demolding is easy. Here, the demolding timing is, for example, a timing at which the hanging jig 11 (see FIG. 4) embedded in the concrete is hardened to a strength that does not come off.
In addition, the amount of movement of the movable wall body 4 shifted from the set position is not particularly limited, and may be a slight gap on the manufacturing yard 2 side (inner surface side).

  Next, as shown in FIG. 9, the movable wall body 4 is disposed again at the set position of the manufacturing yard 2. At this time, in the manufacturing yard 2 surrounded by the fixed wall 3 and the movable wall 4, a plurality of first rectangular blocks 1A, 1A,... ing. The remaining first square block 1A replaces the second-placed formwork, and the place surrounded by the first square blocks 1A, that is, the space place after taking out the formwork block 5 is the second time. This is a placement area (referred to as a second placement area R2).

  Then, the same release agent as described above is applied to the side surfaces of the first square block 1A, the inner surface 3a of the fixed wall 3, the inner surface 4a of the movable wall 4, and the upper surface 2a of the manufacturing yard 2 (see FIG. 3). To do. That is, the release agent is attached to the entire surrounding wall surface except for the upper surface side of the second placement region R2.

  Next, as shown in FIG. 10, the second rectangular block 1B is manufactured by placing concrete in the second placing region R2 using the first rectangular block 1A that has been placed most recently as a mold member. Also in this case, as described above, the hanging jig 11 (see FIG. 4) is embedded in the concrete in each second placement region R2.

  Next, when the mold can be removed after curing the concrete, the movable mold wall 4 is moved outward away from the set position, and then, as shown in FIG. The first rectangular block 1A is taken out from the production yard 2. A third placement region R3 to be placed next is formed in the space after the first rectangular block 1A is taken out.

  Thereafter, the steps from the setting of the movable wall body 4 to the demolding shown in FIG. 9 are repeated. That is, in the second and subsequent placements, in the placement region R arranged in a grid pattern in the vertical and horizontal directions, the portion where the square block 1 functioning as a mold is left and the portion filled with concrete are alternated. In this case, a large number of rectangular blocks 1 are manufactured each time.

Next, the manufacturing method of a square block mentioned above and the effect | action of a square block are demonstrated in detail based on drawing.
In the present embodiment, as shown in FIG. 6, both the vertical direction Y and the horizontal direction X of the rectangular block 1 are included in the manufacturing yard 2 surrounded by the fixed wall 3 and the movable wall 4. By alternately placing the formwork blocks 5 in the arrangement direction, it is possible to form the placement area R of the square block 1, and after placing and hardening concrete in the formed placement area R, By removing the mold, a large number of rectangular blocks 1 can be manufactured at one time.

  In this case, the fixed walls 3 provided on the two orthogonal sides of the manufacturing yard 2 serve as the reference positions in the vertical direction Y and the horizontal direction X in manufacturing the rectangular block 1, so that the accuracy of the manufactured rectangular block 1 is improved. Ensuring and stabilizing the shape can be achieved, and variation in shape can be reduced.

  Further, since two sides of the manufacturing yard 2 are fixed by the fixed wall 3 and the other two sides are movable by the movable wall 4, the movable wall 4 is set when the rectangular block 1 is placed. A free surface can be ensured in the production yard 2 by moving it from the position to the outside of the production yard 2 (see FIG. 8). That is, by moving the movable mold wall 4, the restraining force generated between the rectangular block 1 placed in the manufacturing yard 2 and the formwork block 5 is eliminated and loosening occurs, so that it is easy to remove the mold. .

Furthermore, by placing the formwork members (the formwork block 5 or the remaining square block 1 provided in place of the formwork) alternately in the production yard 2, the placement areas R are also formed every other square block. Therefore, it is possible to replace the first placement region R with the placement region of the mold member. Therefore, for example, in the second and subsequent placements, the most recently placed rectangular block 1 is left in the manufacturing yard 2 to take out the formwork member, and the takeout part of the formwork member is used as the next placement region R. The left rectangular block 1 can be driven as a formwork member.
Manufacturing in this way eliminates the need for assembly and disassembly of the second and subsequent formwork members, improves work efficiency, reduces time, and reduces manufacturing costs. it can.

In the present embodiment, the mold block 5 is manufactured to the same size as the product size of the square block 1, so that the mold block 5 manufactured in advance elsewhere is placed at a predetermined position in the manufacturing yard 2 with a crane or the like. It is possible to easily provide the placement regions R of the rectangular blocks 1 that are alternately formed in both the vertical direction Y and the horizontal direction X of the rectangular blocks 1 simply by hanging them down. This eliminates the time-consuming work of assembling and disassembling a conventional formwork plate as a formwork member, thereby improving work efficiency.
Moreover, since the formwork block 5 is manufactured to have the same dimensions as the product size of the square block 1, when the use as the formwork member is completed, for example, as a square block 1, for example, as a marine block for fishing reefs. It is also possible to use it.

  Further, in the present embodiment, since the rectangular block 1 having the hanging jig 11 on the upper portion 1a as shown in FIG. 4 can be manufactured, when the rectangular block 1 is taken out from the manufacturing yard 2, the hanging jig is used. 11 can be lifted by a crane or the like and easily moved, and the efficiency of manufacturing work can be improved.

  Furthermore, since the concrete of the present embodiment is a material set to 5-12 cm slump, it prevents the soft concrete of slump larger than 12 cm from flowing between the adjacent formwork members to the outside of the formwork member. It is possible to prevent deterioration in quality due to poor filling properties due to slump hard concrete smaller than 5 cm. That is, it is possible to eliminate the problem that the outflow portion is hardened and it is difficult to remove the mold, as in the case where the concrete flows out of the mold member.

  In addition, since a hydrophobic emulsion such as a release agent is applied to the surface having the function of the mold that defines the placement region R, the rectangular block 1 placed in the placement region R can be removed from the mold. It can be done easily.

The square block manufacturing method and the square block manufacturing system according to the present embodiment described above have an effect that the square block 1 can be manufactured easily and efficiently at low cost.

As mentioned above, although the embodiment of the manufacturing method of the square block and the manufacturing system of the square block according to the present invention has been described, the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the present invention. Is possible.

  For example, in the above-described embodiment, the mold block 5 is used only for the first first placement (that is, only the first square block 1A), and the square block that is placed most recently in the second and subsequent placements. Although 1 is used instead of the mold, it is not limited to such a manufacturing method. For example, in the second and subsequent placements, after the movable mold wall 4 is moved, it has a step of removing the rectangular block 1 that has been placed most recently, and the mold block 5 is placed at the same position. Henceforth, it is also possible to repeatedly use this form block 5 as a form member. In this case, by continuously disposing the mold block 5 at the same position in the manufacturing yard 2, it is possible to reduce the time and labor required for setting the mold, so that work efficiency can be improved.

  Moreover, it replaces with the concrete of this Embodiment, and as above-mentioned, as a hydraulic material, it is also possible to use a mixture of steelmaking slag 60 to 70 vol%, blast furnace or blast furnace slag fine powder 10 to 20 vol%, and water 10 to 20%. In this case, it is possible to reuse the material using steelmaking slag and blast furnace or blast furnace slag fine powder generated at the steelworks, so that the material cost can be reduced.

  In the present embodiment, the formwork block 5 is used as the formwork member at the first placement, but the structure of the formwork member is not limited, and the first form mold is used. A well-known formwork plate may be assembled to the frame member to form the placement region R. In short, as the first formwork member, it is possible to adopt a formwork member of any shape and configuration. For those that take time and labor to assemble and disassemble, The manufacturing method using the rectangular block 1 placed as in the above-described embodiment instead of the formwork may be used.

  Further, in this embodiment, the release agent is applied to the mold surface, but a resin sheet may be provided instead of the release agent. In this case, a resin sheet is disposed on the surface having the function of the mold that defines the placement region R, and the concrete (hydraulic material) and the mold of the rectangular block 1 placed in the placement region R Since it is not in close contact with the frame surface, demolding can be performed easily.

  Furthermore, you may make it provide a desired unevenness | corrugation in the casting surface upper surface of the square block 1. FIG. For example, during solidification after the cast concrete has an appropriate hardness, a plate having a concavo-convex pattern formed on the plate surface is pressed from above against the upper surface of the cast surface, and the concavo-convex pattern is applied to the cast surface. By transferring to the upper surface, irregularities can be provided on the square block. In this case, since the uneven | corrugated | grooved part by which the uneven | corrugated process was performed is provided in the casting surface upper surface of the formed square block 1, it can utilize suitably, for example as a marine block used for fishery reef use etc.
