Four-pipe truss structure of prefabricated house

Abstract

The invention relates to a four-pipe truss structure of a prefabricated house. The four-pipe truss structure of the prefabricated house, disclosed by the invention, comprises four-pillar profiled bars and flat head four-pillar connecting pieces or pipe head four-pillar connecting pieces, wherein the four-pillar profiled bars are used as pillars and / or cross beams, and the flat head four-pillar connecting pieces or pipe head four-pillar connecting pieces connect the pillar with the cross beams; the cross section of each four-pillar profiled bar is square; the four-pillar profiled bar comprises square pipes or round pipes respectively located at four corners; the four square pipes or round pipes are fixedly connected into a whole through a plurality of first connecting rods vertically welded between each two adjacent square pipes in a spacing manner; each flat head four-pillar connecting piece comprises a connecting plate and four connecting pipes vertically welded at four corners of the connecting plate; each flat head four-pillar connecting piece consists of a stand pipe part and a horizontal pipe part; the stand pipe part comprises four connecting stand pipes and second connecting rods, wherein the four connecting stand pipes are vertically arranged, and each second connecting rod is horizontally welded between the corresponding two adjacent connecting stand pipes; the horizontal pipe part comprises four connecting horizontal pipes vertically welded onto the two adjacent connecting stand pipes; the extension direction of each connecting horizontal pipe is outward. The four-pipe truss structure of the prefabricated house, disclosed by the invention, is suitable for large-sized combined house structures, and is firm and reliable.

Description

technical field [0001] The invention relates to a four-tube truss structure of a prefabricated house. Background technique [0002] The light steel structure combined house has the advantages of light weight, good earthquake resistance, wind resistance, short construction period, good energy saving performance, flexible pipeline layout, and high degree of industrialization. In the prior art, the light-steel skeleton of a light-steel-structure combined house is spliced ​​by a number of purlins and beams and columns. The purlins and beams and columns are all steel structures, but the steel structure is simple. When the combined house is large, especially when the beams When the suspended width is greater than 8 meters or the floor is greater than 8 meters, simple section steel used as beams or purlins has produced shortcomings such as bending rigidity, low torsional rigidity, and unstable structure, which seriously affects the quality of the house.
