Prefabricated two-side connection steel grid shear wall convenient to replace

Abstract

The invention discloses a prefabricated two-side connection steel grid shear wall convenient to replace. The steel grid shear wall comprises a steel grid shear wall body arranged between frame columnsand frame beams, wherein the steel grid shear wall body is provided with a rectangular frame and a steel grid structure connected with the rectangular frame; and the top and the bottom of the rectangular frame are connected with the corresponding frame beams respectively, the two sides of the rectangular frame and the corresponding frame columns are arranged in a spaced mode, and holes are formedbetween the frame columns and the side edges of the rectangular frame which is arranged with the frame columns in the spaced mode. According to the prefabricated two-side connection steel grid shearwall convenient to replace, the adverse effect of a tension field of a four-side connecting steel plate shear wall on the frame columns can be avoided, and the requirement for door and window openingarrangement in a residential building is met; factory prefabrication can be completely realized, and bolt connection is adopted on site, so that the problems of heavy field welding workload, severe field welding deformation and the like of a stiffened steel plate shear wall are solved; and the weight of components is reduced, so that transportation and installation are convenient, the constructionprogress is accelerated, and the repair period is shortened.

Description

technical field [0001] The invention belongs to the technical field of construction engineering and relates to a steel grid shear wall, in particular to an assembled steel grid shear wall with both sides connected and easy to replace. Background technique [0002] At this stage, my country's residential construction industry has transformed from a total shortage in the past to a structural supply shortage. Problems such as overcapacity of steel in the construction industry, lack of intensification of construction methods, and serious environmental pollution need to be resolved urgently. There is an urgent need to save energy, promote the transformation of construction methods, and high-quality development of urban and rural construction. With the continuous development of my country's new urbanization, residential buildings are the main market demand for prefabricated buildings. In the structural design of high-rise residential buildings, horizontal load is the decisive facto...

AI Technical Summary

Problems solved by technology

For repairable damaged buildings, existing repair measures often require a large number of on-site cutting and welding operations, and the reinforcement effect largely depends on the quality of on-site construction, and there are problems such as difficult transportation of repaired parts in the building and difficult construction. Therefore, the post-repair cycle and repair cost of damaged buildings are increased
