Field cold-bend hyperboloid unit type grating curtain wall system and construction method thereof

Abstract

The invention relates to a field cold-bend hyperboloid unit type grating curtain wall system and a construction method thereof. The grating curtain wall system comprises a building structure and a curtain wall system; the outer side surface of the building structure is a curved surface and is provided with I-shaped steel beams; adapter parts are arranged on the outer sides of the I-shaped steel beams; connecting plates are arranged in the adapter parts; the inner ends of the connecting plates are fixedly connected to the adapter parts; the curtain wall system comprises a keel structure and a grating structure; the keel structure comprises a plurality of stand columns; the outer ends of the connecting plates are inserted into the stand columns; each stand column is provided with two vertical grooves; the grating structure is rectangular and comprises two vertical auxiliary frames; a plurality of transverse gratings are arranged between the inner sides of the two auxiliary frames; the cross section of each auxiliary frame is L-shaped, the inner ends of the auxiliary frames are bent inwards and is fixedly connected to the vertical grooves through third fixing bolts; the two auxiliaryframes of the grating structure are fixed to the outer sides of two adjacent outer columns correspondingly; and three of the four end points of the grating structure are located on the same plane, andthe other one of the end points is not located on the plane.

Description

technical field [0001] The invention belongs to the technical field of building curtain walls, in particular to an on-site cold-formed hyperboloid unit grid curtain wall system and a construction method thereof. Background technique [0002] In the prior art, when it comes to the construction of curved curtain walls of buildings, the following methods are generally considered to realize the curved surface: the profile stretch bending method and the broken line fitting method. [0003] The profile stretch bending method is to bend the profiles of the assembled unit plates in the factory through special stretch bending equipment to form the arc shape required for the curved curtain wall, and then process the above components into arc-shaped unit plates in the factory. Its advantage is that the overall shape of the curved surface of the curtain wall is smooth and beautiful. The disadvantage is that the bending treatment of the profile increases the cost a lot, especially for th...

Problems solved by technology

Its advantage is that the overall appearance of the curved surface of the curtain wall is smooth and beautiful. The disadvantage is that the processing of the profile bending will increase the cost a lot, especially for the hyperboloid shape. If the curved surface is complex and irregular, it will increase the cost and difficulty and the processing cycle. A substantial increase

For its complex and irregular curved surface, it is necessary to make a tire mold for each arc-shaped unit plate. It is obvious that the mold consumption is large and the cost is high.

[0004] The broken line fitting method is to use flat grid unit plates to fit the curved surface of the curtain wall. The cost is relatively low, but the effect of the curved surface is not ideal. division surface intent

When the curvature of the curve is large, the joint edges and corners will be more obvious, and the exterior decoration effect will be poor
