Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cast-in-place concrete shear wall construction, and particularly relates to a shear wall positioning and thickness control device. Background Art
[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls or structural walls, are walls in houses or structures that mainly bear horizontal loads and vertical loads (gravity) caused by wind loads or earthquakes to prevent structural shear (shear) damage. Shear wall structures are extremely common in housing construction projects. Shear wall construction first requires tying steel bars, then setting up formwork, and finally pouring concrete. After the wall takes root, it is also poured from bottom to top. The positioning and thickness control of shear walls are key links in construction, and shear wall positioning and thickness control devices are required.
[0003] Common shear wall positioning and thickness control devices are usually composed of structures such as positioning devices and thickness control devices. The positioning device performs positioning operations by setting reference points, positioning axis lines, installing templates, and positioning steel bars; the thickness control device performs thickness operations by positioning concrete blocks, steel meshes, protective layer control, and pouring control. This is the common structure and use of shear wall positioning and thickness control devices. Traditional shear wall positioning and thickness control devices, at this stage, generally position the shear wall and control the wall thickness by welding steel bars on stirrups after the shear wall steel bars are tied. However, this method has high requirements for welding quality. Secondly, the positioning bars are fixed together with the wall steel bars after all, and the wall positioning effect is average. Finally, it is necessary to wait for the steel bars to be tied before welding the positioning bars, resulting in a long construction time. For this reason, a shear wall positioning and thickness control device is proposed. Summary of the invention
