Construction method of longspan deformed steel joist glass curtain wall

Abstract

The invention discloses a construction method of a longspan deformed steel joist glass curtain wall, and belongs to the technical field of building construction. The implementation manner of the method comprises the following steps that according to a curtain wall design production drawing and field measurement, a radial grid locating line and an annular depth control line of the arc curtain wallare confirmed, and the locating points of stand columns are confirmed; after the locating points of the stand columns are corrected and re-checked and have no error, structural steel joint stand columns are mounted; after the stand columns are mounted, the arc degree, the inclination degree and the up-and-down straightness of the stand columns are checked and adjusted, and it is ensured that the highest points of top double curve arcs are on the same arc and the same elevation; after the stand columns are mounted, cross beams are located through a glass grid, structural steel joist cross beamsare mounted, one ends of the cross beams and the stand columns are welded, and the other ends of the cross beams are hinged to the stand columns; and after the cross beams and the stand columns are mounted and checking is carried out, full welding and fixing are achieved, and locating of a keel system is finished. According to the method, the construction problems about precision control over locating and inclination angles and radians of curtain wall type straightness joint systems and the like can be effectively solved, and therefore construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for a large-span special-shaped steel keel glass curtain wall. Background technique [0002] Nowadays, architecture, a special work, has become a carrier reflecting the social, economic, technological level and cultural concept of an era, and architectural aesthetics is gradually rising to a new level, especially the perfect combination of aesthetic needs and practicality of public buildings. Going up a step, glass curtain walls with tall and large spaces and curtain walls with special-shaped structures are widely used. At present, large-scale co-construction projects mostly use glass curtain wall decoration, and there are many kinds of keels used, including aluminum profile keels, steel keels, pipe trusses, cables and rod systems, pincer steel columns, etc. Compared with the aluminum profile keel glass curtain wall, it is more difficult to co...
