Description

Technical Field

[0001] The present application relates to the technical field of building decoration, and in particular to a connection structure. Background Art

[0002] Large indoor spaces in public buildings usually require suspended ceiling designs. The roof usually uses a steel grid structure to achieve large-span column-free indoor space, and the spacing between the lower chord node balls is generally more than 3 meters. The indoor ceiling cannot be directly suspended on the main steel grid. Usually, a suspended ceiling steel frame and a suspended ceiling transition layer are set to achieve the transition between the steel roof truss and the suspended ceiling. Since the lower chord node ball belongs to the main structure and has a large internal force, the suspended ceiling transition layer cannot be directly welded to the node ball to prevent welding stress or welding instability under high stress. Therefore, a clamp connection method is generally used, or a square steel pipe is directly connected with bolts.

[0003] However, in this current connection method, the grid ball node clamp connector needs to be processed and customized according to the grid ball node diameter, which takes a long processing cycle and reduces work efficiency. In addition, since the height of the ceiling conversion layer is generally high, the workload at high altitude is large, it is difficult for workers to work on their backs, and the installation method is not convenient for the replacement and maintenance of the dome surface materials and the internal equipment of the dome. Therefore, there is room for improvement and development in response to the above problems. Utility Model Content
