Description

Technical Field

[0001] The utility model relates to a concrete wall support reinforcement structure, in particular to a concrete wall single-sided formwork fixing structure. Background Art

[0002] In building construction, it is often necessary to increase the cross-section of load-bearing structures such as beams, columns, and walls for reinforcement. For example, after the construction of concrete walls, the concrete walls usually need to be supported. Most of the existing supporting structures are supported by support piles. However, for some basement buildings, the outer wall range of the basement building is relatively narrow, which makes it impossible to support the formwork, and most of the existing support piles are directly cast together with the outer wall structure of the underground structure of the building, which makes the construction more complicated and the construction efficiency is low. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a single-sided formwork fixing structure for a concrete wall, which can better support the concrete wall and ensure the supporting strength without using diagonal bolts.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A single-sided formwork fixing structure for a concrete wall comprises a plurality of formworks, wherein adjacent formworks are rotatably connected via connecting blocks; the front sides of the plurality of formworks are in contact with the concrete wall, and the back sides of the plurality of formworks are supported by a plurality of supporting assemblies; the supporting assemblies are triangular structures, and a plurality of gaskets are detachably mounted at the bottom of the triangular structures.

[0006] The support assembly comprises a vertical rod, a horizontal rod and an oblique rod, and the vertical rod, the horizontal rod and the oblique rod are fixedly connected to form a triangular structure.

[0007] The gasket is fixedly connected with the vertical rod and the diagonal rod through bolts.

[0008] The formwork plate comprises a plurality of formwork horizontal plates and a plurality of formwork vertical plates, and the formwork horizontal plates are fixedly connected with the formwork vertical plates.

[0009] The supporting formwork and the supporting assembly are connected by bolts.

[0010] The connecting block is an I-shaped structure, and through holes are provided at both ends of the supporting template and the connecting block. The rotating shaft freely passes through the supporting template and the connecting block and is limited by nuts.

[0011] The utility model provides a single-sided formwork fixing structure for a concrete wall, which has the following technical effects:

[0012] 1) By installing gaskets on the lower side of the support assembly, the angle of the support assembly can be adjusted to ensure that the support formwork can better support the concrete wall.

[0013] 2) Connecting blocks are installed between two adjacent supporting templates, so that the supporting templates can be adjusted in quantity at will, and are easy to assemble and fold, making them more convenient to use.

[0014] 3) The device is supported by a triangular structure to ensure support strength. No diagonal bolts are required, and it can support the single-sided formwork of the concrete wall (the supporting formwork fits the formwork and remains fixed after the overall installation of the device is completed).

[0020] like Figure 1-3 As shown, a single-sided formwork fixed structure for a concrete wall includes multiple support components 1 and multiple support formworks 3. The support components 1 are fixedly connected to the support formworks 3. The support components 1 are triangular structures. Multiple gaskets 2 are fixed to the lower side of the support components 1. Multiple connecting blocks 4 are installed between two adjacent support formworks 3. The connecting blocks 4 are rotatably connected to the support formworks 3.

[0021] like Figure 1-2 As shown, the support assembly 1 includes a vertical rod 101, a horizontal rod 102 and an oblique rod 103, which form a triangular structure, and are connected end to end and fixedly connected. The gasket 2 is fixedly connected to the vertical rod 101 and the oblique rod 103 by bolts, and a plurality of reinforcing rods 104 are fixed between the vertical rod 101, the horizontal rod 102 and the oblique rod 103 to improve the support strength.

[0022] Specifically, when support is needed, if the ground is uneven, the number of gaskets 2 can be adjusted to ensure that the vertical rod 101 is in a horizontal state, so as to better support the single side of the concrete wall.

[0023] The formwork plate 3 includes a plurality of formwork horizontal plates 301 and a plurality of formwork vertical plates 302 , and the formwork horizontal plates 301 are fixedly connected to the formwork vertical plates 302 (may be welded).

[0024] The formwork horizontal plate 301 is fixedly connected to the vertical rod 101 by bolts, and the large head of the bolt is located in the countersunk hole on one side of the support form 3 that fits the concrete wall, so as to prevent the bolt from protruding from the support form surface. In addition, through holes are provided at both ends of the formwork horizontal plate 301, which are used for detachable connection with the connecting block 4.

[0025] like Figure 1-3 As shown, the connecting block 4 is an I-shaped structure, and through holes are also provided at both ends of the connecting block 4, and a rotating shaft 5 ( Figure 1-2 The figure is a simplified schematic diagram. Figure 3 The rotating shaft 5 is a rod body with threads at both ends. The rotating shaft 5 can freely pass through the through holes on the formwork cross plate 301 and the connecting block 4, and is limited by nuts at the top and bottom.

[0026] Working principle and process:

[0027] 1) When it is necessary to support a concrete wall on one side, select a suitable number of support forms 3 according to the size of the concrete wall, then connect multiple support forms 3 together through connecting blocks 4, fix the support cross plate 301 to the vertical rod 101 through bolts, and then fix the gasket 2 fixed at the bottom end of the vertical rod 101 to the ground through expansion bolts, so that the concrete wall can be supported.

[0028] 2) When disassembly is required, the bolts between the support assembly 1 and the support template 3 can be removed, and the support assembly 1 and the support template 3 can be disassembled into independent parts; and multiple support templates 3 can be folded up through the connecting block 4 and the rotating shaft 5 for easy use next time.
