Problems solved by technology

[0005] From the structure and construction method of the above-mentioned frame shear wall, it can be seen that the frame unit of each floor of the frame shear structure and the wall concrete unit in the frame unit are all one-time pouring and molding as a whole. When an earthquake occurs, this structure will It is easy to be damaged by the earthquake force as a whole, causing the building to collapse, and the earthquake resistance effect is very poor

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] like figure 1 As shown, the seismic shear wall of the present invention includes two columns 1 , a lower wall unit 2 and an upper wall unit 3 . Of course, although the present embodiment is a two-layer wall unit, in practical application, it may not be limited to two layers, such as four layers, the first and third floors are fixed with the column 1, and the second and fourth floors are slidable.

[0027] The lower wall unit 2 is cast integrally with the two columns 1 on the same floor.

[0028] There is a gap between the upper wall unit 3 and the two columns 1 on the same floor, and a waterproof filler 4 is provided in the gap; the waterproof filler 4 is generally mortar.

[0029] The bottom of the upper wall unit 3 is provided with a bump, and the top of the lower wall unit 2 is provided with a pit corresponding to the bump. There ar...

Abstract

The invention discloses an anti-seismic shear wall and a construction method thereof. The shear wall comprises two stand columns, a lower wall body unit and an upper wall body unit. The lower wall body unit is integrally cast with the two stand columns in the same layer, and a gap exists between the upper wall body unit and the two stand columns in the same layer. Bumps are arranged at the bottomof the upper wall body unit, pits corresponding to the bumps are arranged at the top of the lower wall body unit, the pits are internally provided with left and right two lifting surfaces for liftingthe bumps when the bumps moves laterally to convert kinetic energy into gravitational potential energy, and the bumps are positioned in the corresponding pits. According to key point of the construction method, the wall body units with the bumps and the pits are constructed by using templates with lower bumps and recesses. The anti-seismic shear wall and the method can effectively transform and radiate seismic energy and prevent the wall body and the stand columns from being damaged at a time as a whole.

Description

technical field [0001] The invention relates to the technical field of construction of an anti-seismic shear wall, in particular to an anti-seismic shear wall and a construction method thereof. Background technique [0002] A shear wall is a wall in a building that resists horizontal shear forces. Because the horizontal shear force that high-rise buildings have to resist is mainly caused by earthquakes, shear walls are also called seismic walls. [0003] Most of the shear walls in the prior art are frame-shear structures, which include two columns and multiple beams with different storey heights. Both ends of each beam are fixed to two columns. For example, the ground, two sections of columns on this floor and beams on the first floor constitute frame units, while for other floors, beams on the next floor, beams on this floor, and two sections of columns on this floor constitute frame units. A frame unit is poured with a wall concrete unit. The floor slabs of each floor a...
