Description

Technical Field

[0001] This utility model relates to the field of composite beam technology, and more specifically, to a composite beam for steel structure buildings. Background Technology

[0002] Prefabricated construction is a new type of building production method that uses prefabricated components manufactured in factories and assembled on-site. It achieves sustainable development by standardizing design, factory production, and assembly construction, maximizing the energy efficiency, environmental friendliness, and life-cycle value of building products. In the construction field, especially in steel structure buildings, composite beams play a crucial role as key structural components. Composite beams are generally composed of steel beams and concrete slabs connected by shear-resistant members, and are widely used in large-span, high-load-bearing factories, high-rise buildings, bridge structures, as well as floor slabs, roofs, and industrial building operating platforms.

[0003] Composite beams are assembled from multiple spliced ​​beams. The existing splicing structures are not conducive to limiting the assembly of two beams, resulting in poor limiting effects and easy detachment. Furthermore, the splicing operation is inconvenient, potentially requiring significant manual labor. The use of snap-fit ​​or riveting splicing methods makes assembling composite beams cumbersome, and a certain length of space needs to be reserved for assembly, which not only affects assembly efficiency but also increases the difficulty of assembling composite beams.
