Abstract

The invention relates to an extension-type node, in particular to a rotatable extension-type node and an operation method thereof which are applied to steel structures. The rotatable extension-type node comprises a fixing base and an operating base, the operating base fastened with the fixing base is arranged on the upper portion of the fixing base, an operating hole is formed in the operating base, a slide shaft is arranged in the operating hole, a bearing outer ring is arranged on the inner wall of the operating hole, a bearing inner ring is arranged between the bearing outer ring and the slide shaft, a concave-shaped embedded base groove is arranged in the inner wall of the bearing inner ring, and an ultrahigh molecular polyethylene plate attached to the slide shaft is arranged in the embedded base groove. The operating method is performed in the following steps of node assembling, node positioning and node operating. The rotatable extension-type node and the operation method thereof have the advantages that the structure is compact, requirements on rotation and translation can be met, construction cost is low, and operation efficiency is improved.

Description

technical field [0001] The invention relates to a scalable joint, in particular to a flexible joint with rotation and an operation method thereof, which are applied to steel structures. Background technique [0002] In the prior art, with the continuous emergence of various new structural systems, the connection forms of structures are becoming more and more diverse. In order to meet the needs of structural design, some nodes are required to have the functions of rotating in multiple directions and sliding in one direction. [0003] Chinese patent 201120477422.X discloses a telescopic joint for truss connection that can release temperature stress. The telescopic joint contains two interconnected connection blocks with similar structures. The outlet part or the concave part concave inward, and the inside of the connection block is hollow. The present invention generally adopts two connection blocks as connection nodes of the truss. When the truss expands with heat and con...
