The thickness control of the shear wall formwork steel bar protection layer is a key link to ensure the safety and durability of the concrete structure.

[0003] However, in actual projects, it is difficult to control the thickness of the steel bar protective layer. If the protective layer is too thin, the steel bars may be exposed, thus affecting the durability and safety of the shear wall. If the protective layer is too thick, the volume of the shear wall may increase, increasing material consumption and construction costs, which needs to be improved. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a thickness control device for the protective layer of the shear wall formwork reinforcement, which has the effect of ensuring the construction quality.

[0007] A first hook is vertically arranged on a side wall of one end of the concrete support strip;

[0008] The second hook is bent and arranged on the side wall of the other end of the concrete support bar.

[0009] In a preferred example, the utility model can be further configured as follows: the first pull hook includes a horizontal section and a vertical section that are integrally formed, the horizontal section is located inside the concrete support bar, the vertical section runs through the side wall of the concrete support bar, and the angle between the vertical section and the horizontal section is 90°.

[0010] In a preferred example, the utility model can be further configured as follows: the second hook includes a flat section and a bent section that are integrally formed, the flat section is located inside the concrete support bar, the bent section runs through the side wall of the concrete support bar, and the angle between the bent section and the flat section is 45°.

[0011] In a preferred example, the utility model can be further configured as follows: the concrete support bar includes a pair of end blocks and an intermediate block, the intermediate block has a variety of length specifications and is used alone, both ends of the intermediate block are provided with plug-in blocks, the end blocks are provided with slots for the plug-in blocks to be inserted, and a locking mechanism is provided between the end blocks and the intermediate blocks.

[0012] In a preferred example, the utility model can be further configured as follows: the locking mechanism includes a pair of locking rods and a locking plate, the pair of locking rods are respectively arranged on the end side walls of the middle block and the end block close to each other, the locking plate is used to be sleeved on two adjacent locking rods, and the locking plate is provided with a pair of locking holes for the locking rods to pass through.

[0013] In a preferred example, the present invention can be further configured as follows: the end of the locking rod is threadedly connected with an end cap for pressing the locking plate.

The flat section 31 is located inside the concrete support bar 1, and the bent section 32 runs through the side wall of the concrete support bar 1, and the angle between the flat section 31 and the bent section 32 is 45°.

[0029] The design of the first hook 2 and the second hook 3 can enhance the bonding force between the steel hook and the concrete, and improve the integrity and stability of the structure. At the same time, the steel hook also has good tensile strength and ductility, and can maintain stability when subjected to large tensile forces, preventing the structure from cracking or deformation.

[0030] When supporting the shear wall, the concrete support strip 1 can be placed between the steel meshes on both sides, and the first hook 2 and the second hook 3 can be hooked to the two layers of steel meshes, and tied and fixed with wires. When pouring, the concrete support strip 1 is poured inside the shear wall together, and supports the steel meshes to ensure the pouring thickness. After supporting the formwork, the first hook 2 and the second hook 3 can also be used to hook the side walls of the inner and outer templates to achieve hooking and fixing of the inner and outer templates to ensure the pouring thickness and construction quality.

[0037] When it is necessary to cast shear walls of different thicknesses, the middle block 12 of appropriate length is selected according to the construction requirements, and then the plug blocks 13 at both ends of the middle block 12 are inserted into the slots 14 of a pair of end blocks 11, and then the locking plate 42 is put on the two adjacent locking rods 41, and the end caps 43 are tightened to fix the locking plate 42, so that the connection and fixation between the middle block 12 and the end block 11 can be achieved, and the assembly of the complete concrete support block is completed.
