Abstract
Description
Technical Field
[0001] This utility model relates to the field of template fixing technology, and in particular to a template fixing device for civil engineering. Background Technology
[0002] In modern civil engineering, to speed up the construction of houses, walls are usually poured. During the pouring process, a temporary mold is built using tools such as templates to define the shape of the cement. After the pouring is completed, the wall is left to stand until it solidifies. Then, the templates on both sides are removed. After removal, for the overall aesthetics of the wall, the user will grind and adjust the gaps and angles on the wall surface. At the same time, to prevent the wood used for the template from adhering too much to the wall and damaging it, thus increasing the user's grinding work, bamboo plywood is usually used to build the mold.
[0003] When the wall has right angle edges, the user needs to splice two sets of templates together so that the two sets of templates are at right angles, and then fix them with screws. However, since there is no mechanism to help position the two sets of templates, the templates may tilt during splicing and installation, which will cause the wall to tilt as well, further increasing the difficulty for the user to repair the wall later.
[0004] In response to the above situation, we propose a formwork fixing device for civil engineering. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a formwork fixing device for civil engineering.

[0008] A limiting groove is formed through the interior of the horizontal frame, and a first screw is provided inside the limiting groove. The bottom of the first screw penetrates the upper outer surface of the outer positioning plate and is threadedly connected to the outer positioning plate.
[0009] Preferably, the top of the outer positioning plate and the top of the inner positioning plate are on the same horizontal line.

[0022] Referring to Figures 1-4, a civil engineering formwork fixing device includes an outer positioning plate 1, an inner positioning plate 2 on the inner side of the outer positioning plate 1, a second screw 6 threadedly connected to the upper surface of the inner positioning plate 2, and a horizontal frame 3 rotatably connected to the upper surface of the second screw 6; a positioning groove 4 is opened through the interior of the horizontal frame 3, and a first screw 5 is arranged inside the positioning groove 4; the bottom of the first screw 5 penetrates the upper outer surface of the outer positioning plate 1 and is threadedly connected to the outer positioning plate 1; the top of the outer positioning plate 1 and the top of the inner positioning plate 2 are on the same horizontal line; the outer positioning plate 1 and the inner positioning plate 2 can position the formwork, so that the connection between the formwork will not be misaligned, thereby making the surface of the poured wall smoother.
[0023] A positioning frame 7 is fixedly connected to the top of the inner positioning plate 2. The interior of the positioning frame 7 has a downward-facing sliding groove 8. A sliding plate 9 is slidably connected inside the sliding groove 8. A second lead screw 16 is threaded through the sliding plate 9. The end of the second lead screw 16 near the inner positioning plate 2 is rotatably connected to the inner wall of the sliding groove 8, and the end of the second lead screw 16 away from the inner positioning plate 2 passes through the positioning frame 7 and is rotatably connected to the positioning frame 7. The sliding plate 9 can reinforce the position of the template, thereby making the position of the template more stable.
[0024] A rod 10 is fixedly connected to the bottom of the slide plate 9. A sleeve 11 is slidably connected to the outer surface of the rod 10. A first lead screw 12 is rotatably connected to the bottom outer surface of the sleeve 11. The bottom of the first lead screw 12 is threadedly connected to the inside of the rod 10. Limiting blocks 13 are fixedly connected to both sides of the sleeve 11. A limiting plate 15 is slidably connected to the bottom of the sleeve 11. A limiting groove 14 is opened inside the limiting plate 15. The inner wall of the limiting groove 14 fits against the outer surface of the limiting block 13. The limiting plate 15 extends to the bottom of the outer positioning plate 1. The limiting plate 15 can fix the vertical direction of the outer positioning plate 1, further preventing the template from falling off the device.
[0025] In summary: In the application of this utility model, when building the mold, the user first places a set of templates on a flat surface to make the templates horizontal. Then, the user rotates the first screw 5 and the second screw 6 to adjust the position of the outer positioning plate 1 and the inner positioning plate 2 according to the usage requirements. Then, the user slides the limiting plate 15 to separate the limiting plate 15 from the limiting block 13. Then, the user takes out two sets of templates. The user aligns one set of templates with one right-angled edge of the inner positioning plate 2, and the two sets of templates surround the previously flat template. Then, the user aligns the other set of templates with the other right-angled edge of the inner positioning plate 2 until the end of the other set of templates abuts the outer surface of the first set of templates. Then, the user moves the outer positioning plate 1, so that the inner wall of the outer positioning plate 1 is in contact with the template, and the outer surface of the inner positioning plate 2 is in contact with the template. Then, the user rotates the first screw 5 and the second screw 6 respectively to... The positions of the inner positioning plate 2 and the outer positioning plate 1 are fixed. Then, the user rotates the second screw 16, which causes the slide plate 9 to slide inside the slide groove 8. This allows the slide plate 9 to limit the position of the outer positioning plate 1, thereby allowing the inner positioning plate 2 and the outer positioning plate 1 to clamp the template. Then, the user snaps the limiting plate 15 onto the outer surface of the limiting block 13, so that the top of the limiting plate 15 fits against the bottom of the positioning plate 1. Then, the user first rotates the first screw 12 to move the sleeve 11 upward, so that the limiting plate 15 and the positioning frame 7 can further limit the position of the outer positioning plate 1. Finally, the user uses screws to further fix the structure between the templates. This device fixes the included angle of the two sets of templates from the top of the splice of the two sets of templates, so that the included angle between the two sets of templates is in a right angle state. When the height of the wall to be poured is high, the user uses tools such as a crane for auxiliary installation.
[0026] After one corner is fixed, the user can follow the above steps to fix the other two sets of templates at the other corners of the template, so that the connection between the templates will not be tilted. After the mold is made, the user uses a crane to place the mold on a horizontal ground, so that the corners of the mold are at the same level. Then, pour cement for pouring. After the cement solidifies, first remove the outer positioning plate 1 and the inner positioning plate 2, then remove the template. Then, use a crane to move and assemble the poured cement slab into the corresponding building.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
