Description

Technical Field

[0001] The utility model belongs to the technical field of glass lighting curtain walls, and specifically relates to a connecting device for large-span curtain wall crossbeams. Background Art

[0002] As curtain wall technology matures, curtain walls are widely used in buildings. Angle brackets or spring pins are usually used to connect the glass curtain wall beams to the columns. Before installation, it is necessary to machine installation bolt holes on the columns and connecting angle brackets. The hole diameter is slightly larger than the diameter of the bolts. The connecting angle brackets are fixed to the columns with bolts, and finally the beams are installed. Since the diameter of the connecting bolts (spring pins) is slightly smaller than the installation holes of the columns and angle brackets, there is a certain amount of virtual space between the two. For glass curtain walls with larger horizontal grids, the self-weight of the glass is large, and the glass is located at the front end of the beam. Due to the existence of the virtual space, the front end of the beam sags under the self-weight of the glass, and the rear end tilts upward, which has a poor visual effect in the room and poses a safety hazard.
