Inner inclined support assembled type concrete shear wall prefabricated part

Abstract

The invention discloses an inner inclined support assembled type concrete shear wall prefabricated part. The inner inclined support assembled type concrete shear wall prefabricated part has the characteristics of strong tensile and shock resistance, light damage degree and low bearing capability and rigidity attenuation degree and is capable of effectively limiting or postponing the crack propagation. The inner inclined support assembled type concrete shear wall prefabricated part comprises double rows of reinforcement steel bar meshes, inclined support longitudinal bars and a shear wall, wherein the double rows of reinforcement steel bar meshes consisting of horizontally distributed bars and longitudinally distributed bars are arranged in the shear wall; tie bars are tied arranged between the reinforcement steel bar meshes; the inclined support longitudinal bars are arranged between the horizontally distributed bars and the longitudinally distributed bars; two short steel bars are arranged between the parallel inclined support longitudinal bars; the short steel bars are perpendicular to the inclined support longitudinal bars; the lower ends of the inclined support longitudinal bars are bent and then vertically extend to performed holes; the upper ends of the inclined support longitudinal bars are bent and then vertically extend out of the shear wall. According to the inner inclined support assembled type concrete shear wall prefabricated part, on the basis of common assembled type shear wall reinforcements, the inclined support longitudinal bars are additionally arranged to form a core bundle with inclined reinforced concrete, so that the seismic capacity of the assembled concrete structure is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of building concrete component manufacturing, specifically, it is a prefabricated component of an internal inclined support assembly type concrete shear wall. Background technique [0002] With the development of prefabricated concrete components in China, the shear wall structure, as a main structural system, has attracted more and more attention from the construction industry for its ductility and earthquake resistance. At present, the reinforcement of the widely used shear wall is arranged horizontally and vertically. Under the action of horizontal earthquake force, the main tensile force of the support and the concrete is inconsistent, which cannot limit the generation and development of oblique cracks. Therefore, the existing shear force The strength, bearing capacity and earthquake resistance of the wall structure are all lacking. Contents of the invention [0003] The purpose of the present inventi...
