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, the use of simple section steel as beams or purlins has produced shortcomings such as bending rigidity, torsional rigidity, and unstable structure, which seriously affect the quality of the house

The invention relates to a four-tube truss structure of a prefabricated house. The present invention includes four-column shaped steel used as uprights and / or beams, flat-headed four-column connectors or tube-head four-column connectors for connecting uprights and beams, and the section of the four-column shaped steel is square, including square tubes or round tubes at four corners , four square tubes or round tubes are connected and fixed into a whole through a plurality of first connecting rods welded between two adjacent square tubes or round tubes at vertical intervals; Four connecting pipes welded at the four corners of the connecting plate; the four-column connecting piece of the pipe head is composed of a vertical pipe part and a horizontal pipe part, and the vertical pipe part includes four connecting vertical pipes arranged horizontally; As for the second connecting rod between the two connecting risers, the horizontal tube part includes four connecting horizontal tubes vertically welded on two adjacent connecting risers, and the extending direction of the connecting horizontal tubes is outward. The invention is suitable for large-scale combined house structure 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.
