Protection joint of steel beam on outer wall of fabricated steel structure building

Abstract

The invention discloses a protection joint of a steel beam on an outer wall of a fabricated steel structure building. A prefabricated concrete U-shaped plate opens upwards, a steel bar is buried in the prefabricated concrete U-shaped plate, and the steel bar upwards penetrates out of the prefabricated concrete U-shaped plate and then stretches into a concrete floor in a buried mode. The H-shaped steel beam is mounted in the middle of the prefabricated concrete U-shaped plate, and studs are fixed to top surfaces of upper flanges of the H-shaped steel beam and stretch into the concrete floor ina buried mode. A steel beam web hole is formed in the middle of a web of the H-shaped steel beam, prefabricated U-shaped plate holes are formed in the middles of side walls of two sides of the U shapeof the prefabricated concrete U-shaped plate correspondingly, and split bolts horizontally penetrate through the steel beam web hole and the prefabricated U-shaped plate holes and then are connectedwith nuts in a threaded mode. The protection joint is simple and complete in structure, convenient and fast to construct and high in standard degree, effectively fireproof and waterproof protection onthe steel beam can be achieved, connection with outer wall filling materials is reliable, the quality is stable, and the protection joint can be widely applied to protection modification of H-shapedsteel beams on outer walls of fabricated steel structure buildings.

Description

technical field [0001] The invention relates to a protective node of a steel beam at the outer wall of a prefabricated steel structure building, which can be widely used in the fire prevention, waterproof and anti-leakage of the outer wall steel beam of the prefabricated steel structure building, and a reliable connection node with the outer wall material. under construction. Background technique [0002] In the prefabricated steel structure building, the connection between the outer wall and the steel beam is a very important link. Whether the building structure of the outer wall node is reasonable or not and the quality of the construction directly affect the quality and users of the products in the whole life cycle. experience. Due to the poor convenience of external wall maintenance and high maintenance costs, structural measures need to be taken in the design stage. During the whole life cycle of the building, the external wall and the connection nodes with steel beams...

AI Technical Summary

Problems solved by technology

For the external hanging integral external wall, the fire prevention and waterproofing of steel beams and the connection nodes with external wall materials are relatively easy to handle. One of the current pain points and difficulties, various problems are prominent, and there is no relatively perfect solution at present
