A steel support for building facade structural parts that can be oriented to slide and rotate

Abstract

The invention relates to a directional sliding and rotating steel support used at the support of structural components installed on building facades. The technical problem to be solved is to reduce the influence of the tension force generated by the tension structure itself on the main structure. It is characterized in that: the first fastening steel plate is welded to the outer surface of the rectangular steel sleeve, the annular limiting steel plate is welded to the outer surface of the circular steel sleeve core, the circular steel sleeve core is placed in the rectangular steel sleeve, and the circular steel sleeve core is placed in the rectangular steel sleeve. The outer surface of the steel sleeve core is in contact with the inner surface of the rectangular steel casing. The middle hole of the second fastening steel plate is an elliptical hole with the long axis in the horizontal direction. The circular steel sleeve core can realize the horizontal sliding function in the long axis direction of the elliptical hole, and can rotate freely in the rectangular steel sleeve to realize the rotation of the support. Function; the support of the present invention can realize rotation and directional sliding according to design requirements, and can transmit vertical force in the direction of gravity and horizontal force in the horizontal wind direction; it can be used for self-balancing frame cable structures or other structures with the same force requirements.

Description

technical field [0001] The invention relates to a structural part of construction engineering, in particular to a steel support capable of directional sliding and rotation at the support of the structural component used for building facade installation. Background technique [0002] With the rapid development of my country's economy, many new types of architectural structures have emerged in the construction market, such as frame cable structures and tension string structures. These tensioned structures are derived from the principle of "stretching the bow". The components are light and convenient, and the construction is convenient. The final stress state of the structure is a self-balancing state. The internal forces are all balanced by themselves and have little impact on the main structure. Therefore, they are favored by many engineers. At present, many domestic large-space structure roof string beams and cable structures of glass curtain walls often adopt this type of s...

Problems solved by technology

For structures that require facade installation, such as curtain wall structures, due to the difference in the direction of structural force and displacement constraints, the support used for horizontal surface installation often cannot meet the requirements of facade installation.
