Axial telescopic rigid connection node of large-span glass curtain wall keel and construction method

Abstract

The invention discloses an axial telescopic rigid connection node of a large-span glass curtain wall keel and a construction method, and belongs to the technical field of curtain wall construction. The large-span curtain wall keel reaches a larger span of 19 m and a smaller section diameter of 300 mm, so that glass can be fixed, and self load of a curtain wall is borne; and the keel also can serveas a support component of a roofing structure to bear a structure load. The top of a steel stand column is suspended on the roofing structure, the lower portion is rigidly connected to the ground, and a gap is formed between a lower steel column and the ground; and a certain gap is formed between the lower steel column and the inner wall of a sleeve. The connection node can effectively deal withvertical displacement of an upper roofing, self temperature displacement of the curtain wall keel and overall horizontal displacement of the curtain wall keel, and meets the requirements of rigid connection of the lower end of an upper steel column and axial extension. The connection node successfully solves the contradiction between the appearance and structure stress of a large-span curtain wallbuilding, effectively reduces the section size, improves the span of the keel, meanwhile, improves the construction efficiency, and reduces construction errors.

Description

technical field [0001] The invention relates to the technical field of curtain wall construction, in particular to a large-span glass curtain wall keel axially expandable rigid connection node and a construction method. Background technique [0002] With the rise and development of long-span space structures, the application of glass curtain walls is becoming more and more extensive. Because it can organically unify architectural aesthetics with architectural functions, structures, energy saving and other factors, glass curtain walls are widely loved by architects. [0003] Usually, the curtain wall keel adopts a single larger steel profile or a combined steel truss, and only needs to bear its own load. However, in buildings with unique shapes and complex structures, the curtain wall keel not only needs to fix the curtain wall panel to bear the load of the curtain wall itself, but also needs to be a structural member to bear the force of the main structure. For keels with ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a large-span glass curtain wall keel axially scalable rigid connection node and construction method to solve the problem that the long-span glass curtain wall keel needs to take into account both the aesthetics of the curtain wall and the structural force requirements, and the traditional connection form is difficult to meet the requirements. technical challenge
