Technical Field

[0001] The utility model relates to the field of building connection structures, in particular to a curtain wall connection piece. Background Art

[0002] At present, glass curtain walls are popular in buildings. The curtain walls include keels, curtain wall panels, pressure plates and bolts. The curtain wall panels are carried on the keels, and the pressure plates are pressed on the curtain wall panels. The pressure plates are connected to the keels through bolts, and when the bolts are tightened, the pressure plates are driven to press the curtain wall panels.

[0003] like Figure 6 As shown, the existing curtain wall system connects the curtain wall pressure plate and horizontal and vertical frames by screwing self-tapping screws into the clamps placed in the grooves of the steel profiles; however, the inspection of fasteners should comply with the following regulations: Fasteners should be stainless steel hexagonal bolts, which should be equipped with spring washers. When spring washers are not used, anti-loosening measures should be taken. The main load-bearing rods should not be connected with self-tapping screws.

[0004] In the above curtain wall structure, the screws in the connection structure are load-bearing rods, and the contact points between the screws and the curtain wall are prone to large shear forces and fracture failure, which does not meet the requirements of the specifications and has poor safety and reliability.

[0005] In summary, there is an urgent need to provide a safe and reliable curtain wall connector that complies with regulations and is based on the above-mentioned curtain wall structure. Utility Model Content

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, this embodiment provides a curtain wall connector, including a nut 1, a sleeve 2 and a bolt 3, one end of the sleeve 2 is connected to the nut 1, and the other end is connected to the bolt 3, the shape of the nut 1 matches the keel groove 4, and the nut 1 is clamped in the keel groove 4.

[0036] Working principle: Put the nut 1 into the keel groove 4 from one side of the keel, so that the nut 1 is clamped in the keel groove 4, connect one end of the sleeve 2 to the nut 1, fix the nut 1, and then install the curtain wall system on the keel, and then connect the sleeve 2 with the bolt 3 to tighten and fix the structure between the pressure plate and the keel to achieve the connection of the curtain wall system.

[0037] This solution inserts the nut 1 into the keel groove 4 from one side of the keel, so that the nut 1 is clamped in the keel groove 4, connects one end of the sleeve 2 to the nut 1, fixes the nut 1, and then installs the curtain wall system on the keel, and then connects the sleeve 2 with the bolt 3 to press and fix the structure between the pressure plate and the keel to achieve the connection of the curtain wall system.
