Description

Technical Field

[0001] The utility model relates to the technical field of movable gaskets, in particular to a steel structure movable gasket. Background Art

[0002] Steel structures are made of steel and are one of the main types of building structures. They are primarily composed of steel beams, columns, and trusses made from sections and plates. Rust removal and prevention processes include silanization, pure manganese phosphating, water washing and drying, and galvanizing. Components or parts are typically connected using welds, bolts, or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, high-rise buildings, bridges, and other fields.

[0003] In the prior art, sealing movable gaskets are required when assembling steel structures. A movable gasket is a gasket that can move freely within a certain range and is usually used to adjust the gap, position or angle between equipment or components. There is a composite sealing movable gasket on the market, which is a flat sealing gasket with a metal stamping part as the outer gasket and rubber as the inner gasket. The sealing performance is improved compared with conventional metal gaskets and non-metallic gaskets. However, during use, if any gasket of a composite gasket made of non-metallic gaskets or metal gaskets is damaged, the entire composite gasket will become unusable and need to be replaced as a whole. In the replacement process, the machine needs to be partially or completely disassembled and the composite gasket needs to be replaced as a whole. The replaced composite gasket can only be scrapped, which causes great waste and inconvenience to production. For this reason, we propose a steel structure movable gasket. Utility Model Content
