Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a diagonal brace reinforcement structure for precast concrete wall panels. Background Technique

[0002] With the acceleration of the building industrialization process, traditional in-situ construction is gradually replaced by precast components due to problems such as low efficiency and high pollution. As the core lateral force resisting member, precast shear walls need to meet the requirements of rapid installation and precise positioning. On the construction site, the method of embedded supports is often used to temporarily fix precast reinforced concrete shear wall panels to ensure the accuracy requirements. However, problems such as missing embedding or wrong embedding often occur, and there are also situations where support members cannot be embedded due to construction problems or other reasons on some construction sites. To solve the above problems, the utility model designs a new type of diagonal brace reinforcement structure for precast concrete wall panels. Content of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the utility model provides a diagonal brace reinforcement structure for precast concrete wall panels, effectively solving the problems of being unable to support due to missing embedding or wrong embedding of embedded support members and the situation where support members cannot be embedded due to construction problems or other reasons, ensuring the high-quality completion of construction.

[0004] The utility model realizes the above technical purpose through the following technical means.

[0005] A diagonal brace reinforcement structure for precast concrete wall panels, in which the diagonal brace reinforcement structures are symmetrically arranged on both sides of the precast wall panel, including a bottom horizontal pattern steel plate member and a vertical pattern steel plate member with a "U" - shaped round steel welded on the surface, and also including diagonal brace members. One end of the diagonal brace member is connected to the round steel on the bottom horizontal pattern steel plate member, and the other end is connected to the round steel on the vertical pattern steel plate member. The pattern surface of the bottom horizontal pattern steel plate member is closely attached to the floor slab, and the pattern surface of the vertical pattern steel plate member is closely attached to the precast wall panel; an embedded bolt is also arranged in the precast wall panel. One end of the embedded bolt extends out of one side of the precast wall panel and passes through the bolt installation hole opened on the vertical pattern steel plate member on this side, and is fixed tightly by a nut.

[0006] Furthermore, both the bottom horizontal pattern steel plate member and the vertical pattern steel plate member are made of 20 - mm - thick pattern steel plates, and round steel with a diameter of 16 mm is welded on the back of the pattern steel plate for connection with the diagonal brace members, and the weld thickness is 8 mm, with double - sided full - weld.

[0007] Furthermore, both ends of the diagonal brace members are rotary clamping mechanisms, and the rotary clamping mechanism is a combined structure of a nut and a screw rod. By rotating the main rod members of the diagonal brace members on both sides of the precast wall panel, the precast wall panel can be clamped.

[0008] The utility model has the following beneficial effects:

[0009] The utility model can largely solve the problems of missing or misplacing the embedded support parts of precast wall panels at present, which cannot be reinforced, and the problem of inability to embed support parts due to construction problems or other reasons, ensuring the high-quality completion of construction, improving the first-pass rate of construction quality, and effectively increasing the structural safety.
