Description

Equal-strength connecting structure and curtain wall system Technical Field The utility model belongs to the technical field of building curtain walls, and particularly relates to a constant-strength connecting structure and a curtain wall system. Background The building curtain wall is used as a peripheral protection structure system widely adopted in modern buildings, is essentially an external wall structure without bearing, and has the main functions of realizing the isolation and protection of the interior and the external environment of the building and improving the overall appearance quality of the building. The building curtain wall is generally composed of two major parts, namely a decorative and protective panel of a surface layer, which comprises various materials such as glass, metal plates, stone, ceramic plates and the like, and a supporting system which is positioned behind the panel and bears structural loads, wherein common forms comprise aluminum alloy cross beams, upright posts, steel structural members, end supporting members of the cross beams and the like. In the whole curtain wall system, the aluminum alloy cross beam is used as a core component of the supporting structure, so that not only is the mechanical function of effectively transmitting external forces such as panel load, wind load, earthquake force and the like to the main structure of the building carried out, but also the structural rigidity, stability and safety of the whole curtain wall system are determined. However, when two beams are required to be butted along the horizontal direction to form a longer beam, a welding mode is generally adopted, the operation is complex, the subsequent installation and maintenance are inconvenient, the beam is generally of a hollow structure, and the strength of a joint is often insufficient through welding. Disclosure of utility model The embodiment of the application aims to provide an equal-strength connecting structure, which aims to solve the problem of how to connect two cross beams and improve strength.
