Description

A shear wall formwork fixing device

Technical Field

The utility model belongs to the technical field of shear wall construction, and in particular relates to a shear wall formwork fixing device.

Background Art

Shear wall, also known as wind-resistant wall or earthquake-resistant wall, is a wall in a building structure that bears horizontal loads caused by wind loads or earthquakes. It can prevent structural shear damage and has a good ability to bear vertical loads. It is mainly used in high-rise and super-high-rise buildings to increase the stability and safety of the building.

During the pouring process of the shear wall, the shear wall formwork needs to be installed according to the designed shear wall size and shape, and then the on-site pouring is carried out. The shear wall formwork used in the prior art is generally composed of multiple rectangular shear wall formwork monomers. In order to avoid the phenomenon of formwork running and expansion when pouring concrete, the formwork is usually fixed with the help of main back ribs, secondary back ribs, tension bolts, etc. after the splicing is completed. However, the following problems still exist in the actual construction process: 1. In the process of setting up the formwork, the adjacent formworks are not accurately positioned, and there is a gap at the formwork docking position. During the pouring process, the formwork will bear a large lateral pressure of concrete, which may easily cause the problem of slurry running at the joint of the formwork docking position, affecting the pouring quality of the shear wall; 2. Holes need to be opened on the shear wall formwork to reserve tension screw holes. Since the formwork is relatively thick, when the formwork is installed, multiple workers are required to cooperate in adjusting the formwork so that the ends of the tension screws can pass through all the holes on the formwork. The formwork erection process is cumbersome and the construction efficiency is low. In addition, there are a large number of holes on the used formwork, which cannot be reused, resulting in a large waste of formwork materials, thereby increasing the construction cost.
