Steel structure beam column

Abstract

The invention discloses a steel structure beam column. The steel structure beam column comprises a stand column, wherein a groove is formed in the stand column; the stand column is connected with a cross beam through the groove; rotating grooves are symmetrically formed in the two sides of the cross beam; supporting rods are rotationally connected into the rotating grooves through pin shafts; sliding grooves are formed in the supporting rods; extension rods are connected into the sliding grooves in a sliding mode; the extension rods penetrate through the sliding grooves; the ends, located outside the supporting rods, of the extension rods are rotationally connected with movable seats through pin shafts; and bases are welded and fixed to the bottoms of the movable seats. The steel structure beam column has the advantages that when connecting blocks are pressed into the groove, straight rods slide, so that compression springs in an extrusion state in a cavity are pushed into a cavity; and the compression springs release stored elastic potential energy, so that a baffle is pushed to slide, a fixing block is clamped between two triangular blocks, the two triangular blocks cannot be retracted, then the cross beam is fixed, the strength of the cross beam is guaranteed, and meanwhile, the installation process is convenient and rapid.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a steel structure beam and column. Background technique [0002] The advantages of light weight and high strength of steel make steel structures widely used in the construction industry, especially in long-span airport terminals, convention centers, stadiums and super high-rise buildings. With the improvement of my country's comprehensive national strength and the rapid development of steel production and steel smelting technology, a large number of steel structure buildings have been built all over the country. Steel structure connecting members refer to the interconnected carriers between steel structure components or parts. Prefabricated steel structure buildings and prefabricated steel structure bridges are mostly connected by on-site assembly and connection of steel structure connecting members. Compared with traditional cast-in-place concrete structures, the work e...

Problems solved by technology

[0003] The existing beam-column joints of steel structures are mostly fixed by welding when they are fixed to steel beams. Although the stability is strong, it is extremely inconvenient to disassemble and recycle, resulting in great economic waste. At the same time, the steel beams fixed by bolts Beams can easily lead to the fracture of the connection point between the steel beam and the load-bearing column, which has caused great trouble to the user, and when the general steel beam is installed, the stagnation phenomenon of the clamping point often occurs, which leads to deformation of the clamping point, reducing the The problem of the service life of the joints. The existing steel structure connecting members are at the connection between the steel beam and the steel column. The contact area is small, and the connection stability is not high. It is difficult to align the threaded holes precisely, resulting in deviation during installation, which affects the accuracy of installation, and even causes damage to the connection between the steel beam and the steel column.
