A composite steel member whose height can be adjusted finely

Abstract

The invention discloses a composite steel member whose height can be finely adjusted, comprising a top plate, a slanting beam and a base, including a top plate, a pair of supporting slanting beams and a base, and the two supporting slanting beams are intersected between the top plate and the base ; The bottom surface of the top plate and the upper surface of the base are provided with a guide groove and a plurality of transverse grooves, and the parallel guide grooves and the transverse grooves are vertically intersected; a pair of limit plates are provided inside the transverse grooves to fit with them; The tops and bottoms of the two supporting inclined beams are provided with guide blocks that slide and fit with the guide grooves, and a transverse threaded sleeve is fixed in the middle of the guide grooves of the base, and a threaded rod is respectively installed at both ends of the threaded sleeves. , the outer ends of the screw rods respectively abut against the guide blocks, and at least two square gaps for wrench operation are arranged in the middle of the screw rods. The height of the steel member can be fine-tuned through the adjustment of the threaded sleeve, and the device adopts the way of crossing two oblique beams, which can further improve the supporting force and increase the overall supporting strength of the factory building.

Description

technical field [0001] The invention relates to the technical field of composite steel structures, in particular to a composite steel member whose height can be finely adjusted. Background technique [0002] In recent years, the superiority of light steel structure workshops has become more and more recognized by people, and has gradually become a new hotspot in plant technology. In North America, Europe and other countries, light steel structure buildings have become a common structural system. The proportion of structural workshops has grown from 5% in the early 1990s to 25% now. The light steel structure housing system is characterized by its highly industrialized production methods and efficient on-site installation levels, as well as the excellent use of new and healthy household product concepts. , accepted by more and more people. [0003] However, the supporting steel parts used in the existing light steel structure factory buildings are usually only simple "I" stee...

Problems solved by technology

[0003] However, the supporting steel parts used in the existing light steel structure factory buildings are usually only simple "I" steel or "T" steel. In a multi-storey factory building, its supporting force is relatively weak, its shockproof ability is relatively low, and it cannot effectively prevent the corrosion of steel components. When the house encounters bad weather, it is easy to tilt, and the house collapses, causing casualties. Adjust the support angle and height according to your own needs
