Salt) and organic media (except bitter edible plant solvent).
Ultra-high molecular weight polyethylene board is the key that this node can slide, and ultra-high molecular weight polyethylene board is positioned at bearing
In the embedded foundation trench of circle, this embedded foundation trench can limit the movement of ultra-high molecular weight polyethylene board.Use superhigh molecular weight polyethylene
Alkene plate can increase lubrication, it is ensured that the more preferable sliding of node.
Sliding axle can use rustless steel or ordinary steel as required, need to arrange in end limiting plate meet structure spacing want
Ask.
The effect of the present invention and advantage:
1, meeting structure design needs, solving integrated steel-structure from node not only had needed to rotate but also need the need of translation
Ask.
2, construction cost is low.Ultra-high molecular weight polyethylene board has self-lubricating, high abrasion, shock resistance, low temperature resistant, chemically-resistant
The performances such as product, add the service life of this node, decrease regular maintenance simultaneously, and corresponding Financial cost is minimized.
3, construction efficiency is high.This node can be transported to scene after factory's entirety installs, and job site only need to be by pedestal and pin
Axle is fixed, and method is simple, and effect is obvious.
Therefore, the stretch nodes that a kind of band of the present invention rotates, compact conformation, meet needs and rotate and the need of translation
Asking, construction cost is low, improves operating efficiency.
