Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a formwork for manufacturing a six-legged concrete block, which is used when manufacturing a six-legged concrete block mainly used for wave dissipation.

``Prior art'' Various types of formwork have been considered and used for manufacturing hexapod concrete blocks conventionally used for wave dissipation, but all of them have many types of parts and the manufacturing cost of the formwork is low. The drawbacks were that it was expensive and took time to assemble and disassemble.

"Problems to be solved by the present invention" In view of the above-mentioned drawbacks of the conventional methods, the present invention reduces the number of types of parts to reduce the manufacturing cost of formwork, and also makes assembly and disassembly easier. The purpose is to obtain formwork for the production of hexapod concrete blocks.

``Means for solving the problem'' This invention makes it possible to manufacture a hexapod concrete block by assembling 12 frames, 24 top frame plates, and 5 horizontal frame plates. .

"Embodiments of the present invention" The present invention will be described in detail below with reference to embodiments shown in the drawings.

In the embodiments shown in FIGS. 1 to 11, 1 is a rectangular prism-shaped projecting leg 2a, 2b, as shown in FIG.
2c, 2d, 2e, and 2f are formworks for producing a hexapod concrete block 3 that protrudes radially in six directions, and this formwork 1 includes the projecting legs 2a, 2b, 2c, 2
d, 2e, 2f, and 12 L-shaped bent frames 4 that can be assembled to be located at the corners of the frames 4; ,2c,2d,2e,
24 upper lid mold frame boards 5 that cover the 2f side wall, and 5 horizontal frame boards that cover the other 5 open ends excluding the upper part of the mold assembled with the frame 4 and the upper lid mold frame board. It consists of 6.

The frame 4 has the projecting legs 2a, 2b, 2c, 2d, 2e, 2 as shown in FIGS. 3 to 6.
The tip chamfering members 8, 8 and the protruding legs 2a, 2b, 2 capable of forming the tip chamfered portion 7 of f.
A corner chamfering member 10 that can form approximately half of the chamfered portion 9 of the corners c, 2d, 2e, and 2f;
10, and a plurality of bolt insertion holes 1 protruding from both ends of the chamfered end members 8, 8 of the frame body 11.
2 and a plurality of bolt insertion holes 12 protruding from both sides of the corner chamfered members 10, 10 of the frame body 11.
It is composed of mounting flanges 14, 14 having .

As shown in FIGS. 7 and 8, the upper lid frame plate 5 includes a rectangular upper lid frame plate main body 15 and a mounting flange 13 of the frame 4 integrally formed around the upper lid frame plate main body 15. .

As shown in FIGS. 9 and 10, the horizontal frame plate 6 corresponds to a rectangular horizontal frame plate main body 17 and mounting flanges 13 and 14 of the frame 4 integrally formed around the horizontal frame plate main body 17. Mounting flange 1 having a plurality of contacting bolt insertion holes 12
8, 18, 18, 18.

The formwork 1 with the above configuration uses a plurality of bolts 19 and nuts 20, and first, the 12 frames 4 are brought into contact with the mounting flanges 14, 14 of the frames 4, respectively, so that the outline of the hexapod concrete block 3 is formed. After assembly, attach the mounting flange 1 of the frame 4.
The mounting flanges 16, 16, 16, 16 of two upper lid frame plates 5 are brought into contact with the upper cover frame plates 5, 3 and 14, respectively, and assembled using a plurality of bolts 19 and nuts 20. Next, the mounting flange 18 of the horizontal frame plate 6 is brought into contact with the mounting flange 13 of the frame 4 at the open end excluding the upper part assembled with the frame 4, and assembled using a plurality of bolts 19 and nuts 20. Now, the assembly of the formwork 1 is completed as shown in FIGS. 1 and 2, and concrete is poured through the upper opening 21 to form the hexapod concrete block 3 as shown in FIG. 11. I can do it.

In addition, the mold opening may be removed by separating the entire frame 4, or it may be removed by separating into at least four pieces, for example, with a plurality of frames 4 and a plurality of horizontal frame plates 6 connected. You can.

Note that the frame 4 may be assembled and removed from the frame 4 in an embodiment in which the upper lid type frame plate 5 is attached.

In the above embodiment, the projecting legs 2a, 2b, 2 are in the shape of a square prism.
Although the formwork for manufacturing a hexapod concrete block in which c, 2d, 2e, and 2f protrude radially in six directions has been described, the present invention is not limited to this. The same method can be applied to a formwork for manufacturing a hexapod concrete block 3A having legs protruding radially in six directions. In this case, the L-shaped frame is made by connecting two trapezoidal frames bent into an L-shape at the base, and the upper lid frame plate is also formed into a trapezoidal shape. ``Effects of the present invention'' that can be achieved by using the present invention As is clear from the above explanation, the present invention has the following effects.

(1) Since it is composed of 12 L-shaped bent frames, 24 upper cover frame plates, and 5 horizontal frame plates, only three types of parts are required to make up the formwork. , the number of types of parts can be significantly reduced compared to conventional ones, and manufacturing costs can be reduced.

(2) According to (1) above, each component has a simple and small shape and is highly compatible, making it easy to transport and handle.

(3) According to (1) above, when demolding and assembling, it is possible to demold and assemble at least four parts in a state where a plurality of parts are assembled, resulting in good workability.

(4) According to (1) above, since it can be assembled into a formwork having an opening only at the top, concrete can be poured once and efficient work is possible.

(5) The upper cover form board attached to the frame can be removed after concrete pouring work and unevenness caused by air bubbles on the top surface of the projecting legs can be leveled with a trowel.

(6) Since it has a structure in which the upper cover form plate is attached to the frame, the strength of the upper cover form plate can be maintained even if the upper cover form plate is made of plywood or FRP.

Therefore, by using plywood or FRP,
The weight of the formwork can be reduced, making it easier to handle.

(7) Since it can be handled with the top cover type frame plate assembled to the normal frame, the number of parts is small and handling is easy.
