Description

Technical Field

[0001] The invention relates to the technical field of irregular curved surface curtain wall construction, and in particular to an irregular curved surface curtain wall fine steel keel installation system and a construction method. Background Art

[0002] With the development of the construction industry, large buildings continue to emerge, and curtain walls of various shapes have gradually become a mainstream demand. In order to meet this demand, curtain walls as the outer wall enclosure of buildings have been given new requirements, which are reflected in the panels and structures that have various special-shaped changes according to the requirements of the building shape, achieving a certain architectural art effect. This unique curtain wall is also called a special-shaped curtain wall.

[0003] Usually, the curved glass curtain wall is relatively regular, and the rotation angle of the glass on the same column is consistent, so the normal installation method can be used for installation and construction. However, when the curved curtain wall has many irregular shapes, due to the different and irregular twisting angles of the columns, if the conventional method (column → beam → etc.) is still used, the "space point selection" error will be very large, and the installation efficiency will be very low (each small column must be measured and positioned). At the same time, due to the large and irregular entry and exit positions of the curtain wall finished surface, the outdoor hanging basket and scaffolding cannot be set up normally, which further limits the installation quality and efficiency of the curved curtain wall to a certain extent. Summary of the invention

[0004] The purpose of the present invention is to provide an installation system and construction method of a refined steel keel for an irregular curved curtain wall to solve the technical problems described in the background technology.

[0007] Preferably, in order to improve the structural strength of the keel truss and ensure the stability of the curved curtain wall, two adjacent keel trusses are connected as a whole through a connecting beam, and the connecting beam is horizontally arranged, and its two ends of the beam body are respectively welded between two correspondingly arranged connecting beams.

[0008] Preferably, at least two connecting beams are provided at each connecting beam, and the two connecting beams are respectively arranged at the top of the front curtain wall panel and the bottom of the rear curtain wall panel. On the one hand, the connecting beams can connect several keel trusses into a whole, and on the other hand, they can also serve as the edge sealing structure of the curtain wall panel to improve the installation stability of the curtain wall panel.

[0009] Preferably, the top of the connecting beam is closed by a sealing aluminum plate, and a decorative line is installed at the front end of the connecting beam. The sealing aluminum plate and the decorative line can play a decorative role as well as a waterproof and vapor-proof sealing role.

[0010] Preferably, in order to facilitate the installation of the attachment columns and make the attachment columns better fit the structural floor, attachment panels are welded and fixed at both ends of the attachment columns. The attachment panels are attached to the structural floor of the main structure and anchored to the main structure through connecting bolts or embedded parts.
