Description

Technical Field

[0001] The present invention belongs to the field of building construction technology, in particular to the field of building exterior wall construction technology, and relates to a hanging and fixing structure for a building exterior wall decoration surface, and specifically to a keel-free point-hanging exterior wall hanging and fixing system that can be adjusted in multiple dimensions. Background Art

[0002] The existing point-hung exterior wall system has the advantage of being able to save a lot of keel costs, but it also loses the adjustment function between the keel and the main body, the vertical keel and the horizontal keel, and has the defects of small installation space, small adjustable space, and few adjustable methods.

[0003] Typically, existing point-hanging exterior wall technologies use angle steel adapters to connect directly to the main building, which results in the adapters being adjustable only in the Y-axis direction, and unable to be adjusted in the X-axis horizontal direction or around the X-axis direction; at the same time, for the angle steel adapters, when subjected to gravity loads, downward bending moments and outward pulling forces are applied to the anchor bolts, and this force-bearing mode places very high demands on the bonding quality between the anchor bolts and the wall.

[0004] Chinese application 201911196818.4 discloses a point-hung curtain wall system, which includes a surface material and a hanger structure. The surface material is directly connected to the structural wall through the hanger structure to form a point-hung, keel-free curtain wall structure system. The hanger structure includes a wall connecting member, a transition member, an upper hanger and a lower hanger. The curtain wall surface material of this application is directly connected to the structural wall through the hanger structure to form a point-hung, keel-free curtain wall structure. Compared with the existing curtain wall structure with a keel frame, its overall structure is simple. The surface material and the hanger are installed as a whole in the factory to form a small unit, which is hung on site. It is convenient and fast to install and the connection is stable and reliable. However, the structural performance of each component of this application is insufficient and cannot meet the further safety, stability and speed requirements of the point-hung curtain wall system.
