Description

Technical Field

[0001] The utility model relates to the technical field of steel structure buildings, in particular to a special-shaped lattice support structure based on steel structure buildings. Background Art

[0002] Traditional steel structures include steel frame structures, central support steel frame structures, eccentric support steel frame structures, cold-bent thin-wall light steel systems and other structural systems. Due to the problem of exposed columns and beams in the structural frame system, the use and aesthetics of the structural space are affected. In addition, the beam-column connection nodes of the current steel structure are welded, which is far from achieving the purpose of rapid installation and the construction quality is difficult to control. The reasons of exposed columns and beams and connection technology have seriously restricted the development of steel structures in the field of assembly, and can no longer meet the current national requirements for steel structure assembly.

[0003] The utility model with publication number CN 215519244 U discloses a novel prefabricated steel structure system with special-shaped lattice columns, which is a lateral force resisting structure system composed of special-shaped lattice columns and steel beams. The special-shaped lattice columns include "L"-shaped lattice columns, "T"-shaped lattice columns, and "X"-shaped lattice columns. The side chords of the special-shaped lattice columns are I-shaped steel side chords or steel tube side chords. Concrete filling is added to the steel tube side chords to form steel tube concrete; the diagonal web members are eliminated to form a hollow truss lattice column; the connection between the special-shaped lattice column and the steel beam adopts a lattice column disconnection type and a beam through-type connection.

However, the above-mentioned special-shaped lattice columns are connected by welding of various reinforcing connecting rods, and this welded connection method cannot be adjusted and changed according to the needs of the site.
