Prefabricated box plate steel structure multi-high-rise structure system and construction method

Abstract

The invention provides a prefabricated type box plate steel structure multi-storey and high-rise structural system and a construction method. The prefabricated type box plate steel structure multi-storey and high-rise structural system comprises a ground floor unit and standard floor units. The ground floor unit is composed of steel plate walls, a steel floor and precast concrete slabs. Each standard floor unit is composed of steel plate walls and a steel floor. Vertical reinforcing ribs are welded to the inner side of each steel plate wall. Reinforcing ribs are welded to the bottom side of each steel floor. The precast concrete slabs are attached to the outer sides of the steel plate walls of the ground floor unit. During an earthquake or large storey drift, the precast concrete slabs cangenerate certain sliding relative to the steel plate walls of the ground floor unit. The prefabricated type box plate steel structure multi-storey and high-rise structural system is high in bearing capacity, good in ductility and anti-seismic property, rapid in construction, low in work quantity, low in pollution on a construction site and low in comprehensive construction cost, and the prefabricated type box plate steel structure multi-storey and high-rise structural system can be widely applied to high-rise civil residential buildings.

Description

technical field [0001] The present invention generally relates to the field of building structure engineering, and mainly relates to a prefabricated box-plate steel structure, in particular to a prefabricated box-plate steel structure multi-high-rise structure system and a construction method, which can be used for prefabricated box-plate steel structure multi-high-rise residential buildings. Background technique [0002] The prefabricated box-plate steel structure is a new structural system composed of ribbed steel plates that can be applied to residential buildings. The monolithic wall of the prefabricated box plate steel structure has the following characteristics: there is no surrounding frame to restrain the steel plate; there are vertical stiffeners on one side of the steel plate to form a stiffened steel plate wall structure; the stiffened steel plate wall needs to directly bear the vertical load. The floor of the prefabricated box-slab steel structure is a steel plat...

AI Technical Summary

Problems solved by technology

However, when the prefabricated box-slab steel structure system is applied to a high-rise building, the stiffened steel plate wall at the bottom will bear a large vertical load and horizontal load, and the reinforced steel plate wall at the bottom will undergo a large displacement or even be damaged under the earthquake
