AI Technical Summary

Technical Problem

When existing unit curtain walls are installed in steel structure buildings, they will have an adverse impact on the stability of the steel structure, and deformation of the steel structure can easily lead to extrusion damage of the curtain wall.

Method used

The connection system between the cantilevered steel beam and the curtain wall is adopted. By setting up upper and lower adapters on the top and bottom of the cantilevered steel beam, upper and lower pendants are installed on the curtain wall keel. Adjustment bolts and gap design are used to achieve fine adjustment of the height of the curtain wall keel and the displacement of the curtain wall panel, and the structural strength of the connecting node is enhanced.

Benefits of technology

It effectively reduces the impact of the self-weight of the unit curtain wall on the stability of the steel structure, and when the steel structure is deformed, the damage to the curtain wall panel is avoided through displacement design, which improves the construction efficiency and connection stability.

Abstract

The utility model discloses a connecting system of a cantilever steel beam and a curtain wall, which belongs to the technical field of steel structure curtain wall construction and comprises the cantilever steel beam, a curtain wall keel, a curtain wall panel, a canopy keel and a canopy. An upper adapter and a lower adapter are arranged at the top and the bottom of the cantilever steel beam respectively; an upper hanging piece and a lower hanging piece are arranged on the curtain wall keel; the upper hanging piece is hung on the upper adapter piece; the lower hanging piece is hung on the lower adapter piece; the curtain wall panel is connected with the curtain wall keel; the canopy keel is arranged at the top of the cantilever steel beam; and the canopy is mounted on the canopy keel. According to the utility model, the cantilever steel beam and the upper and lower adapters are respectively reinforced, so that the structural strength of the connecting node is improved; the adjusting bolt is arranged on the upper hanging piece, the gap is formed between the lower hanging piece and the lower adapting piece, fine adjustment of the height of the curtain wall keel is facilitated, the gap is formed between the upper curtain wall face plate and the lower curtain wall face plate, when a steel structure deforms, the connecting joint and the curtain wall face plates can both meet displacement of a certain space, and the curtain wall face plates are prevented from being damaged.
