Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically to concrete support formwork for building construction. Background Technology

[0002] Concrete formwork is a temporary structure used in building construction to define the shape and size of poured concrete. This structure has functions such as load-bearing, shaping, and preventing tilting. It is usually made of wood, steel, aluminum alloy, or composite materials. Formwork is widely used in the construction of concrete structures such as foundations, beams, columns, walls, and floor slabs, and is an important tool to ensure construction accuracy and safety.

[0003] However, existing concrete wall support formwork structures generally suffer from problems such as complex assembly and disassembly, unstable positioning, and low component reuse rates. This is especially true for double-sided support, where rapid clamping and uniform stress distribution are difficult to achieve. Furthermore, traditional support anchors have a simple structure, hindering rapid disassembly and recycling after construction, thus increasing construction costs. Therefore, there is an urgent need for a simple, reliable, easy-to-assemble and disassemble, and reusable double-sided concrete wall support device to improve support efficiency and wall construction quality.

The support effect is stable, it is easy to disassemble and reuse, and the cost of formwork is reduced.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete support formwork for building construction, comprising a first support plate and a second support plate.

A limiting plate is welded to the outer wall of the internally threaded cylinder, and a bolt passes through the limiting plate. One end of the bolt is threadedly connected to the outer wall of the second support plate. A conical nut is threadedly connected to the outer wall of the support anchor. Multiple conical grooves are equidistantly arranged from top to bottom on the outer wall of the first support plate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 The present invention provides a concrete support formwork for building construction, comprising: a first support plate 2 and a second support plate 7.

[0020] Among them, such as Figures 1-3 As shown, multiple support anchors 3 are equidistantly arranged from top to bottom on the outer wall of the first support plate 2. The outer wall of the support anchor 3 is provided with threaded grooves. One end of the support anchor 3 passes through the first support plate 2 and the second support plate 7 respectively. The adjacent sides of the first support plate 2 and the second support plate 7 are attached to the concrete wall 1. The support anchors 3 pass through the first support plate 2, the concrete wall 1 and the second support plate 7 to achieve double-sided clamping of the concrete wall 1.

[0021] In this embodiment, as Figures 1-4 As shown, one end of the support anchor rod 3 is threadedly connected to an internal threaded cylinder 5, and a limit plate 4 is welded to the outer wall of the internal threaded cylinder 5. A bolt 6 passes through the limit plate 4, and one end of the bolt 6 is threadedly connected to the outer wall of the second support plate 7. A conical nut 13 is threadedly connected to the outer wall of the support anchor rod 3. Multiple conical grooves 14 are arranged at equal intervals from top to bottom on the outer wall of the first support plate 2.

[0022] In use, the outer wall of the support anchor rod 3 is tightened with the tapered nut 13 through the external thread, and the tapered nut 13 is pressed into the tapered groove 14 of the first support plate 2 for self-locking. The end of the support anchor rod 3 is connected to the internal threaded cylinder 5, and the limiting plate 4 is welded on the internal threaded cylinder 5. The limiting plate 4 is locked to the second support plate 7 by bolts 6 to form a force-closed structure.

[0023] Furthermore, the opening size of the conical groove 14 matches the outer diameter of one end of the conical nut 13. The matching and engagement of the conical groove 14 and the conical nut 13 achieves automatic alignment and locking, enhances the connection strength, and prevents slippage.

[0024] In this embodiment, as Figure 1 As shown, a fixing plate 8 is fixedly connected to the outer wall of the first support plate 2. A support column 9 is hinged to one side of the fixing plate 8, and a base plate 10 is hinged to the end of the support column 9. Through the multiple hinge connections between the fixing plate 8, the support column 9, and the base plate 10, the support column 9 provides a stable support structure when unfolded, enhances the overall structural load-bearing capacity, and facilitates the folding and storage of the base plate 10.

[0025] Furthermore, the bottom of the base plate 10 is provided with multiple fixing pins 11. The base plate 10 uses the fixing pins 11 at its bottom to insert into the ground or positioning holes to achieve positioning and fixing of the base plate 10 to the ground, thereby improving the stability of the support column 9 when it is supported.

[0026] like Figure 1 and Figure 2 As shown, the first support plate 2 has multiple limiting grooves 12 arranged at equal intervals from top to bottom on the side away from the conical groove 14. When the second support plate 7 is removed, the limiting plate 4 can be embedded in the limiting groove 12, and the conical nut 13 can be rotated to fasten the limiting plate 4 in the limiting groove 12, which facilitates the storage of the limiting plate 4 after the second support plate 7 is removed.

[0027] Based on the above technical solution, the working steps of this solution are summarized as follows: When this utility model is used, the support anchor rod 3 penetrates the first support plate 2, the concrete wall 1 and the second support plate 7 to achieve double-sided clamping of the concrete wall 1. The outer wall of the support anchor rod 3 is tightened with the conical nut 13 through the external thread, and the conical nut 13 is pressed into the conical groove 14 of the first support plate 2 for self-locking. The end of the support anchor rod 3 is connected to the internal threaded cylinder 5, and the limiting plate 4 is welded on the internal threaded cylinder 5. The limiting plate 4 is locked to the second support plate 7 by the bolt 6 to form a force-closed structure. The distribution of multiple support anchor rods 3 makes the two plates evenly stressed and have high rigidity, ensuring the size and flatness of the concrete wall 1 during pouring. When the support formwork is removed, the conical nut 13 and the bolt 6 are loosened, and the components can be quickly recycled and reused, thereby saving the cost of using concrete support formwork.

[0028] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
