Description

Technical Field

[0001] The utility model relates to the technical field of steel structure installation, in particular to a steel structure quick installation clamp. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. It is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The characteristics of steel are high strength, light weight, good overall rigidity, and strong resistance to deformation. Therefore, it is particularly suitable for building large-span, super-high, and super-heavy buildings; the material has good homogeneity and isotropy, and is an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well; the construction period is short, the degree of industrialization is high, and specialized production with a high degree of mechanization can be carried out. Among them, the components or parts of steel structures are usually connected by welds, bolts or rivets. When installing steel structures, the joints of the steel structures need to be aligned to ensure the tightness of the connection. However, when the steel structures are clamped after being butted, any slight offset will lead to reduced butt joint accuracy at the joints of the steel structures. During installation, due to the fixed connection between the clamp and the steel structure, the clamp may block the installation of the steel structure, making the installation inconvenient. For this reason, we proposed a quick installation clamp for steel structures. Utility Model Content
