Description

Technical Field

[0001] The utility model relates to the technical field of shear walls, in particular to an earthquake-resistant shear wall. Background Art

[0002] Shear wall, also known as wind-resistant wall, earthquake-resistant wall or structural wall, is a wall in a house or structure that mainly bears horizontal loads and vertical loads (gravity) caused by wind loads or earthquakes to prevent structural shear (shear) damage. It is also called earthquake-resistant wall and is generally made of reinforced concrete. It is divided into plane shear wall and cylinder shear wall. Plane shear wall is used in reinforced concrete frame structure, lifting plate structure and beamless floor system. In order to increase the rigidity, strength and anti-collapse ability of the structure, reinforced concrete shear wall can be cast in place or prefabricated in some parts.

[0003] Please refer to the seismic shear wall with announcement number CN210032221U. When an earthquake occurs, the first buffer energy-absorbing layer deforms to absorb the seismic energy, preventing cracks in the wall due to absorbing too much seismic energy. The coordination of the positioning rod and the positioning hole enables the wall to be assembled with the base accurately. In addition, the coordination of the positioning rod and the positioning rod limits the displacement between the wall and the base, preventing the wall from being completely separated from the base when the earthquake level is too large, thereby causing the building to collapse.
