Description

Building steel structure coupling assembling Technical Field The utility model relates to the technical field of constructional engineering, in particular to a constructional steel structure connecting assembly. Background In the field of modern buildings, building steel structures become a core structural form of large-scale buildings and high-rise buildings by virtue of the advantages of high strength, light weight, short construction period and the like. The I-shaped steel is used as an important component of a building steel structure, has good bending resistance and stability due to the unique cross section shape, and is widely applied to key stress components such as beams, columns and the like. However, due to the limitation of transportation conditions and construction processes, in practical engineering, multiple sections of the construction steel are often required to be in butt joint so as to meet the length and bearing requirements of a building structure; At present, the butt joint of I-shaped steel adopts welded fastening's mode generally, makes I-shaped steel connect as an organic wholely through high temperature molten metal, and though joint strength is higher, later stage if need dismantle because of building function change, structural maintenance or transformation, need use cutting equipment to destroy the welding seam, not only operation complicacy, inefficiency, still cause the damage to I-shaped steel parent metal easily, influence its reuse. Disclosure of utility model Aiming at the defects that the high-temperature molten metal is used for connecting the I-shaped steel into a whole, although the connection strength is higher, if the structural maintenance or the transformation needs to be disassembled due to the change of the building function, the welding seam is destroyed by using cutting equipment in the later period, the operation is complex, the efficiency is low, the parent metal of the I-shaped steel is easy to damage and the reutilization of the parent metal is influenced, the utility model provides the building steel structure connection assembly, which has the advantages of high connection strength and convenient disassembly, and solves the problems mentioned in the background art.
