Ultra-high molecular weight polyethylene board is the key that this node can slide, and ultra-high molecular weight polyethylene board is positioned at the embedded foundation trench of bearing inner race, and this embedded foundation trench can limit the movement of ultra-high molecular weight polyethylene board.Use ultra-high molecular weight polyethylene board to increase lubricated, guarantee the better slippage of node.
Sliding axle can adopt stainless steel or ordinary steel as required, limiting plate need be set in end and meet the spacing requirement of structure.
Effect of the present invention and advantage:
1, meet structure design needs, from node, solved the demand that integrated steel-structure had not only needed to rotate but also need translation.
2, construction cost is low.Ultra-high molecular weight polyethylene board has the performances such as self-lubricating, high abrasion, shock resistance, low temperature resistant, chemicals-resistant, has increased the application life of this node, has also reduced regular maintenance simultaneously, and corresponding financial cost is minimized.
3, construction efficiency is high.After this node Ke factory integral body installs, be transported to scene, job site only need be fixing by pedestal and bearing pin, and method is simple, and effect is obvious.
Therefore, a kind of stretch nodes with rotation of the present invention, compact conformation, the demand of satisfy the demand rotation and translation, construction cost is low, improves operating efficiency.
