Description

Technical Field

[0001] The utility model belongs to the technical field of purlin connection, and in particular relates to a novel steel purlin connection structure. Background Art

[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 beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. 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 other fields. Purlin is one of the common components in steel structure buildings. Purlin is also called purlin or truss. It is a horizontal roof beam perpendicular to the roof truss or rafters to support the rafters or roofing materials. Purlin is a transverse bending member and is generally designed as a single-span simply supported purlin.

[0004] When the purlin connection structure is in use, when the two C-shaped steel purlins are under pressure, the pressure will be concentrated above the C-shaped back-to-back fitting of the two purlins. When the pressure is too large, the top of the C-shaped steel purlin will bend at the junction with the web, causing the entire purlin to bend and tilt to one side, resulting in a significant reduction in the bearing capacity.
