Problems solved by technology

[0005] There are three main problems in applying the low-rise cold-formed steel composite building structure of the related technology to the multi-storey building structure: First, under the doubled vertical load, the current single C-shaped steel wall column section size cannot meet the strength and stability requirements; the second is that the structural lateral stiffness and strength cannot meet the requirements of relevant specifications (regulations). To achieve the purpose of overall anti-side work, it is often to add uplift anchor bolts and shear bolts between the upper and lower discontinuous walls; in multi-layer structures, the wall caused by the deformation of the anchor bolts The overall rotation deformation will not be negligible, and will significantly reduce the stiffness and bearing capacity of the structure; third, the roof is not suitable for multi-storey residential buildings due to problems such as vibration and sound insulation

Abstract

The invention relates to a residential structure of multi-storey cold-formed steel composite building, which comprises a plurality of wall body units, roof units and joist guide rail which is connected with the wall body and the roof respectively, wherein, the residential structure of multi-storey cold-formed steel composite building also comprises square tubular columns arranged vertically at two ends of the wall body units, the roof units comprise a flat plate part and a joint embedded in the flat plate part, the materials of the flat plate part are light weight building boards, and the wall body units are provided with strengthened section columns for bearing the joint load of the roof units. The invention is applicable to constructing multi-storey buildings.

Description

technical field [0001] The invention relates to a composite house structure, in particular to a multi-layer cold-formed steel composite house residential structure. Background technique [0002] Cold-formed steel, also known as cold-formed thin-walled steel, is formed by cold-working steel sheets, steel strips, steel plates or flat steel bars, and the common thickness is 0-2mm. Compared with traditional hot-rolled section steel, cold-formed steel can economically obtain a more reasonable cross-sectional shape, and then obtain a satisfactory strength-to-weight ratio. [0003] The low-rise cold-formed steel composite house structure of the related technology includes a house skeleton composed of cold-formed steel columns, guide rails and joists, and walls and roofs fixed on the house skeleton by self-tapping screws, wherein the cold-formed steel columns It is a single C-shaped section; the wall and roof are made of profiled steel plate, oriented structural board (English full...
