Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a template removal tool. Background Art

[0002] After the concrete construction is completed, the formwork needs to be removed. The tools used to remove the formwork in the prior art basically use the principle of levers to pry a single formwork to achieve the formwork disassembly operation. The existing formwork removal tools have the following problems when in use: first, the contact area between the end of the tool and the side edge of the formwork adjacent to the formwork to be removed (i.e., the support point) is small. When applying force to pry, the force is concentrated at one point, which easily causes deformation of the side of the formwork. At the same time, the operation is laborious, affecting the construction efficiency. Secondly, the overall structure of the existing demolding tools is basically fixed, especially the operating rod. The position of the operating rod cannot be adjusted according to the prying situation of the formwork, and external force cannot be better applied. The flexibility of use is low and the operation is inconvenient. Therefore, there is an urgent need for a formwork removal tool that can increase the contact area with the support point and adjust the position of the operating rod during operation. Utility Model Content

[0003] The purpose of this utility model is to provide a template removal tool, which can use the arc-shaped support plate to increase the contact area with the template, avoid damage to the side of the template during work, and ensure the service life of the template; at the same time, the position of the operating lever can be adjusted to better apply force, reduce labor intensity, and improve the convenience of template removal.

[0020] The following is a clear and complete description of the present invention with reference to the accompanying drawings and embodiments:

[0021] like Figures 1 to 4 As shown, the template removal tool of the present invention includes a support plate 1, which is an upwardly convex arc-shaped structure. A mounting frame 2 is coaxially arranged inside the support plate 1. A rotating shaft 3 is movably arranged in the middle of the mounting frame 2. A ratchet 4 and an operating lever 5 are arranged on the rotating shaft 3. A ratchet 6 is provided on the mounting frame 2 on one side of the ratchet 4 and meshes with the ratchet 4. The ratchet 6 is elastically mounted on the mounting frame 2. A connecting plate 7 is provided at one end of the support plate 1. A pry bar 8 is vertically arranged on the end of the connecting plate 7 away from the support plate 1. When working, the pry bar 8 is inserted into the fixing hole on the side wall of the template to be removed, and the support plate 1 contacts the side of the template to be removed. Then, the operating lever 5 is rotated with the contact point between the support plate 1 and the side of the template as a fulcrum. At this time, the pry bar 8 will pull the template to be removed loose, thereby separating it from the adjacent template. At this time, the state of the operating lever 5 can be adjusted as needed to put it in a position convenient for applying force. The operating lever 5 can be rotated again to further pry out the template. The structure is simple, easy to operate, and highly practical.

[0022] Furthermore, the mounting frame 2 is a hollow cylindrical structure with an adjustment slot 9 defined in its sidewall, providing space for adjustment of the operating lever 5. The ratchet 4 and ratchet teeth 6 are both located within the cavity within the mounting frame 2. Furthermore, in this embodiment, the pry bar 8 has a threaded surface and is threadedly connected to the connecting plate 7, allowing for flexible adjustment of the length of the pry bar 8 protruding from the connecting plate 7 according to the depth of the template fixing hole.

[0023] In this embodiment, two connecting plates 7 are preferably provided, and the two connecting plates 7 are symmetrically arranged on either side of the support plate 1. The provision of two connecting plates 7 facilitates the use of pry bars 8 on the two connecting plates 7 to connect to the fixing holes on both sides of the formwork during the formwork removal, satisfying the prying operation on both sides of the formwork to ensure smooth disassembly of the formwork. A connecting sleeve 10 is provided at the end of the support plate 1. The connecting plate 7 is connected to the connecting sleeve 10 and can be rotated and adjusted relative to the connecting sleeve 10. Therefore, when prying on one side of the formwork, the position of the connecting plate 7 on the other side can be adjusted to avoid obstruction when prying the formwork.

[0024] Specifically, a positioning groove 11 is provided at one end of the connecting sleeve 10 close to the connecting plate 7, a positioning sleeve 12 is provided on the connecting plate 7, and a positioning rod 13 matching the positioning groove 11 is provided in the positioning sleeve 12. The positioning groove 11 is a regular polygonal structure. When the positioning rod 13 is inserted into the positioning groove 11, the positioning operation of the connecting plate 7 can be realized, thereby ensuring the stability of the connecting plate 7 during operation; the positioning sleeve 12 and the connecting sleeve 10 are elastically connected by a spring 14, wherein the spring 14 is sleeved on the outside of the positioning rod 13, and the spring 14 is rotatably connected to the connecting sleeve 10, so that when the connecting plate 7 needs to be rotated, the connecting plate 7 is pulled up to move the positioning rod 13 out of the positioning groove 11, and the connecting plate 7 is rotated at the same time. Preferably, a rotating ring 15 is movably provided in the connecting sleeve 10 above the positioning groove 11, and the bottom of the spring 14 is connected to the rotating ring 15. A through hole matching the positioning rod 13 is preferably provided in the middle of the rotating ring 15, so that when the connecting plate 7 needs to be rotated and adjusted, the positioning rod 13 is moved out of the positioning groove 11 and into the through hole in the middle of the positioning ring to drive the rotating ring 15 to rotate together with the spring 14, thereby preventing the spring 14 from being twisted due to the rotation of the rotating ring 15 driven solely by the spring 14. In addition, the positioning sleeve 12 and the connecting sleeve 10 have the same diameter, and the end surfaces of the positioning sleeve 12 and the connecting sleeve 10 that contact each other are provided with mutually meshing positioning teeth 16 to further ensure the stability of the connecting plate 7 in the working state.

[0025] Furthermore, a positioning plate 17 is provided on the support plate 1. The positioning plate 17 extends to the rotating shaft 3. A positioning cap 18 is slidingly provided on the positioning plate 17. The positioning cap 18 is perpendicular to the positioning plate 17. After the rotating shaft 3 is movable out of the mounting frame 2, a positioning block 19 is provided. The positioning block 19 is a cross-shaped structure. The positioning cap 18 is provided with a positioning groove 11 that matches the positioning block 19. By sleeved with the positioning cap 18 on the positioning block 19, the rotating shaft 3 can be positioned. This can be used in situations where there is no need to adjust the state of the operating lever 5, ensuring the stability of the operating lever 5 during operation. Specifically, a slide bar 20 is provided on the positioning plate 17. The positioning cap 18 is slidingly provided on the slide bar 20. To prevent the positioning cap 18 from rotating along the slide bar 20, the slide bar 20 can be set to a polygonal structure, such as a triangular or quadrilateral structure, or as Figure 4 As shown, the slide rod 20 is set to a cylindrical structure with a limit groove 21 provided thereon. A limit block slidably connected to the limit groove 21 is provided in the positioning cap 18 so that the positioning cap 18 can only be adjusted by sliding along the length direction of the slide rod 20.

[0026] When the utility model is in use, the pry bar 8 is inserted into the fixing hole on the side wall of the template to be removed, and the support plate 1 contacts the side of the template adjacent to the template to be removed. Then, the operating rod 5 is rotated with the contact point between the support plate 1 and the side of the template as the fulcrum. At this time, the pry bar 8 will pull the template to be removed loose, thereby achieving separation from the adjacent template. The template to be removed can be pried from both sides according to the template setting to achieve smooth disassembly of the template. The utility model is easy and quick to operate, has a simple structure and is highly practical.
