[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and bridges.

[0003] Among them, the steel structure purlin is a horizontal component distributed along the length of the roof, located on the main rafters, supporting the secondary rafters. In the sloping roof, it is often placed on the roof truss or inclined beams, and the ceiling and waterproof layer are laid on it as the attached component of the water-following bar. At present, the purlins used in a large number of light steel structure houses are mostly steel structures, and their cross-sectional shapes are generally "[" or "Z" shaped. The lower end face is used to connect with the beam, and the upper end face is used to connect with other attached assemblies. The cross-sectional shape of the purlin of this structure is unreasonable, and the mechanical properties of various parts of the material are not fully utilized, resulting in both waste of materials and reduced mechanical stability of the components under load-bearing state. It is not convenient for the stable docking and stable use of the purlins. For this reason, we provide a combined steel structure purlin to solve the above problems. Utility Model Content
