Mass production formwork for square pillar block

Abstract

To provide a formwork with which it is possible to manufacture many products at once by setting up multiple rows of molds in one flat mold, while it has not been possible to make a large number of, for example, triangular prism blocks at once.SOLUTION: A diagonal partition frame 5 and a diagonal partition frame 6 of a different direction are assembled in a cross-shaped pattern with notches to interlock with each other. Multiple frames are prepared by combining each frame to form multiple rows of triangular prism blocks. Separately from this, a frame is prepared in which column-direction side frames 7 are interposed between column-direction intermediate plates 8 on both sides. Notches are made in the former and latter frames so that they can interlock with each other. The latter is assembled so that it interlocks with the former from above, forming a single formwork. By removing the column-direction intermediate plates 8, a gap 13 is created between the formwork and the triangular prism blocks, allowing the triangular prism blocks to be taken out.SELECTED DRAWING: Figure 6

Description

[Technical Field]

[0001] The present invention relates to a formwork for manufacturing a large number of prismatic blocks at once. [Background technology]

[0002] As an example of a prismatic block, a triangular prism-shaped block will be described.

[0003] As a triangular prism-shaped block (hereinafter referred to as a triangular prism block), a block with a shape similar to that of the triangular prism proposed by the present applicant is known (Patent Documents 1 and 2). As shown in Figures 1 to 3, a formwork for manufacturing such a shape is created by arranging triangular prism blocks 4 in a row, alternating their orientations, with a partition frame 1 sandwiched between them, and then closing the formwork with side frames 2 on both open sides. After concrete or other material is poured into the formwork and allowed to harden, the side frames 2 are removed and the triangular prism block 4 is taken out of the formwork.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-205103 [Patent Document 2] Utility Model Registration No. 3238745 Summary of the Invention [Problem to be solved by the invention]

[0005] The above-mentioned formwork had the problem that only one row could be made per formwork, making it impossible to produce many triangular prism blocks at once. However, the present invention makes it possible to make two or more rows instead of one row. The object of the present invention is to provide a formwork that can produce many triangular prism blocks at once using multiple rows. [Means for solving the problem]

[0006] The formwork of the present invention is assembled by intersecting a diagonal partition frame 5 and a diagonal partition frame 6 of a different direction, with notches provided so that they can interlock. This is done by combining multiple frames of each type to form multiple rows of triangular prism blocks. Separately, a frame is prepared in which column-direction side frames 7 are sandwiched between column-direction intermediate plates 8 on both sides. Notches are provided so that the former and latter frames can interlock with each other. The latter are then assembled so that they interlock from above, forming one formwork. [Effects of the Invention]

[0007] In the present invention, even if a triangular prism block 10 is located next to the triangular prism block 9 to be removed and these triangular prism blocks are in close contact with each other, preventing the removal of the triangular prism block and other components such as formwork, the column-direction intermediate plate 8 between the two triangular prism blocks can be slid upward and removed. The resulting gap 12 can be used to create a gap 13 between the column-direction side frame 7 and the triangular prism block 9. Furthermore, by slightly shifting the frames around the block using this gap 13, similar gaps can be created in the diagonal partition frame 5 and the diagonal partition frame 6. Similar gaps can also be created in all triangular prism blocks in the other formwork. As a result, all of the formwork can be removed. This makes it possible to manufacture many triangular prism blocks at once. [Brief explanation of the drawings]

[0009] Figures 5-7 show an embodiment of the present invention after material has been poured into a formwork and hardened. In the formwork state shown in Figure 5, triangular prism block 9 is in close contact with triangular prism block 10 from another row. This prevents triangular prism block 9 from being removed. From this state, gap 12 is created by shifting the column-direction intermediate side panel 8 upward and removing it, as shown in Figure 6. This gap 12 is then used to peel the column-direction side frame 7 away from triangular prism block 9, creating gap 13, as shown in Figure 7. Repeat this process to create gaps 13 for all other triangular prism blocks. Furthermore, this gap 13 is used to slightly shift the triangular prism block and the frame surrounding it. Gaps can also be created between the diagonal partition frame 5 and the diagonal partition frame 6 and the triangular prism block. Gaps can also be created in the same way for all triangular prism blocks in the formwork. As a result, the entire formwork can be removed. This allows for the production of many triangular prism blocks at once. [Explanation of symbols]

Claims

[Claim 1] The column-direction intermediate plate (8) between the two square pillar blocks is slid upward and removed to create a gap between the column-direction side frame (7) and the square pillar block.
