Structural system of industrial low storied dwelling

Abstract

The invention belongs to the field of building structures, and in particular relates to a structural system of an industrial low storied dwelling adopting modularized design, factory production and field mounting. The structural system of the industrial low storied dwelling comprises steel columns, steel girders, inter-column supports, steel girder horizontal supports, floor slabs, connecting nodes between the steel columns and a foundation, the connecting nodes between the steel columns and the steel girders, the connecting nodes between the steel columns and the inter-column supports, the connecting nodes between the steel girders and the steel girder horizontal supports, rigid connection nodes between the steel girders, the connecting nodes between the steel girders and the floor slabs, roofing surrounding systems and wall surface surrounding systems, wherein the steel columns are connected with the foundation through pre-embedded bolts; the steel columns are connected with the steel girders through bearing type high-strength bolts; the steel columns are connected with the inter-column supports through ordinary bolts; the steel girders are connected with the steel girder horizontal supports through the ordinary bolts; the steel girders are in fully rigid connection through continuous girders; the slabs are connected with the steel girders through male pins or special fasteners; and each of the roofing surrounding systems and the wall surface surrounding systems is of a block type. The structural system of the invention has the characteristics of clear stress of the structure, simple component connection, convenient and quick mounting, attractive appearance, good rationality and economical efficiency of unit steel amount, and is favorable for industrial production.

Description

technical field [0001] The invention belongs to the field of building structures, in particular to an industrialized low-rise residential structure system that adopts modular design, is manufactured in a factory, and is installed on site. Background technique [0002] At present, the structural system of domestic steel structure residences mainly adopts the traditional frame structure system. Although this structural system has many advantages compared with reinforced concrete structures, there are many deficiencies in the application of low-rise residential buildings. The main problems are as follows: 1. The bay and span of low-rise residential buildings are relatively small, and the traditional frame structure cannot take advantage of the advantages of steel structures in large spans; 2. Due to the limitations of traditional frame structures, structural columns cannot be made too small. In low-rise residential buildings, if the walls need to Covering the steel columns will...

Problems solved by technology

[0005] The present invention aims to overcome the problems of unclear force transmission, unreasonable steel consumption per unit, complex connection nodes, troublesome processing and installation, unfavorable for industrialized production, and industrialized factory manufacturing when traditional frame structures and thin-walled steel structures are applied to low-rise residential buildings. The disadvantages of low degree, difficulty in quality assurance and poor thermal insulation performance of building materials
