Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall keels, in particular to a keel structure which is convenient for installing a curtain wall. Background Art

[0002] The connection between the curtain wall and the keel is usually achieved by using specially designed connectors, such as angle brackets, bolts, etc. These connectors will be fixed on the keel, and then the aluminum alloy profiles of the curtain wall will be connected to the keel through these connectors. This connection method can ensure the stability and sealing of the curtain wall.

[0003] The existing Chinese utility model patent with reference announcement number: CN218323367U discloses a keel structure for glass curtain wall installation, including a main keel, a first limiting groove and a second limiting groove, the upper side of the main keel is provided with a first limiting groove, the two sides of the main keel are provided with a second limiting groove, an L-shaped fixing plate is provided inside between the first limiting groove and the second limiting groove, and a group of first screws are provided between the bottom end of the L-shaped fixing plate and the main keel. The utility model is provided with an L-shaped fixing plate inside between the first limiting groove and the second limiting groove, and a group of first screws, a second screw and a plurality of first springs and a second spring are provided between the L-shaped fixing plate and the main keel, so that the first screw and the second screw are rotated to drive the L-shaped fixing plate to move, thereby fixing the glass curtain wall, and can be adjusted according to the thickness of different glass curtain walls, so that it is more convenient to use and effectively improves the applicability of the device.

[0004] During the installation of the existing curtain wall, since the angle brackets are fixed on the keel, it is necessary to first limit the position of the curtain wall, and then connect the curtain wall to the angle brackets on the keel with bolts. This method needs to limit the rotation angle of the curtain wall during the installation process, otherwise the installation position of the curtain wall will deviate, resulting in the inability of the curtain wall to fit with the surrounding curtain walls, affecting the installation of the remaining curtain walls, which is very inconvenient. In addition, during the installation of the existing keel structure, the main beam and the cross beam are fixed by bolts, and the cross beam needs to be kept horizontal and connected to the main beams on both sides. The cross beam angle cannot be limited during installation, and the cross beam may tilt. Utility Model Content
