Factory assembled latticed light steel structure and manufacturing method thereof

Abstract

The invention discloses a factory assembled latticed light steel structure and a manufacturing method thereof. The factory assembled latticed light steel structure consists of frameworks distributed at interval and in parallel and cross beams fixedly connected between the frameworks; each framework comprises two latticed columns and a roof truss fixedly placed between the tops of the two latticed columns; each latticed column comprises two relatively parallel sheet columns, a middle support connecting plate connected between the two sheet columns through self-tapping screws, foundation connectors connected to the bottoms of the sheet columns through self-tapping screws, and roof truss connectors connected to the tops of the sheet columns through self-tapping screws; and each roof truss comprises two relatively parallel trusses and a middle support connecting plate connected between the two trusses through self-tapping screws. The light steel structure does not require welding, and is good in universality and strong in interchangeability; and the bearing capacity and the rigidity of node buckling plates are improved by stamped pressure ribs specially designed on the node buckling plates.

Description

technical field [0001] The invention relates to a small and medium-sized light steel structure for a workshop with a span of less than 30 meters. Background technique [0002] Shaped steel frames and cold-formed thin-walled steel frames have the characteristics of reasonable stress, good seismic performance, convenient fabrication, and fast construction speed, and have been widely used in recent years. Traditional steel structural columns and cold-formed thin-walled steel frames are generally made of steel plates, square (rectangular) tubes, round tubes, profiled steel, angle steel, etc. over 3mm, which are welded with rods to form steel structural columns or cold-formed steel frames. Bent thin-walled steel frame. [0003] The light steel structure in the traditional factory building with a span of less than 30 meters is generally connected by welding. Welding is a direct connection between steel structure columns and rods. Although this connection has a large bearing capac...
