Abstract

The invention relates to the technical field of fixed buildings, in particular to a gravity type damping filling wall which comprises a frame structure, two brickworks arranged in the frame structure side by side, and prestress ribs located on the two sides of the two brickworks and crossed at the diagonal position of the frame structure. A steel groove support is arranged below each brickwork. The two ends of each steel groove support are connected with the ground through opposite supporting legs respectively. Slide grooves are formed in the supporting legs. V-shaped supports are arranged between every two opposite supporting legs. The two ends of each V-shaped support are arranged in the slide grooves of the corresponding supporting legs on the two sides. Slide wheels are arranged at the bottom ends of frame columns of the frame structure. The top ends of the prestress ribs are fixed to the upper portion of the frame structure. The bottom ends of the prestress ribs are wound around the slide wheels and fixed to the middles of the V-shaped supports on the corresponding sides. By stretching or releasing the prestress ribs, the field angles of the V-shaped supports are changed. The two brickworks in the frame structure deform in the lateral direction of the frame structure so as to vertically and oppositely move, and therefore energy consumption happens to a damping medium in the filling wall, and the risks of cracking breakage and plane outward collapse of the filling wall are reduced.

Description

technical field [0001] The invention relates to the technical field of fixed buildings, in particular to a gravity damping filling wall. Background technique [0002] The reinforced concrete frame structure has the advantages of flexible building layout and large indoor space, and is widely used in office buildings, schools, hotels and other buildings. The overall anti-seismic performance of engineering structures after anti-seismic fortification has been greatly improved, effectively reducing earthquake disasters, but it also shows that there are still many problems in anti-seismic design. Influence; the frame structure after the seismic design did not appear the "strong column weak beam" failure mode with good ductility and so on. Due to the poor shear strength and deformation capacity of the infill wall itself, it cannot achieve deformation coordination with the surrounding reinforced concrete frame structure under strong earthquake action, resulting in serious damage to...
