Description
[technical field]
The present invention relates to friction coat and the method for pot bearing in bridge construction, particularly highway, railway bridge beam type seat structure and the friction coat born between vertical load contact surface thereof and spraying method.
[background technology]
The principle of work of highway, railroad bridge pot bearing: common laminated rubber bearing is by multilayer rubber and stiffened steel plates, and steel plate all wraps in the rubber support formed in rubber elastic material.Sheet-type support has enough vertical rigidities with pressure-bearing vertical load, the counter-force of superstructure reliably can be passed to pier, have good elasticity, to adapt to the rotation of beam-ends; There is again larger shearing strain to meet the horizontal shift of superstructure.The board-like rubber support of tetrafluoroethylene is that the poly-tetrem fluorine plate of bonding thick layer 7mm on common laminated rubber bearing forms.Except vertical rigidity and the recoverable deformation with common laminated rubber bearing, vertical load can be born and adapt to outside beam-ends rotation, because the low-friction coefficient (μ≤0.08) between polyfluortetraethylene plate and beam bottom stainless steel plate can make the horizontal shift of bridge superstructure unrestricted.But although poly-tetrem fluorine plate has lower frictional coefficient in actual applications, crush resistance and wear resistance poor, can not meet actual needs.So in order to meet poly-tetrem fluorine plate crush resistance and the higher performance requriements of wear resistance, carrying out modification to poly-tetrem fluorine plate and becoming inevitable.But modified poly-tetrem fluorine plate, although performance increases, cost increases, expensive.Although also select ultrahigh molecular weight polyethylene(UHMWPE) to replace modification to gather tetrem fluorine plate, meet the demand of bridge, the price of ultrahigh molecular weight polyethylene(UHMWPE) costly.In addition, although modified Teflon plate and ultra-high molecular weight polyethylene board can meet the requirement of bridge to crush resistance, wear resistance, frictional coefficient, but the associativity between sheet material and bearing becomes the maximum hidden danger in bridge use procedure, often because combine between sheet material and bearing loosely, cause slippage, occur accident.Our company will provide antifriction coat highway, railroad bridge pot bearing and production technology thereof, process implementing is simple, cost is lower, antifriction layer can form one with ground securely, avoid the shortcoming of sheet material, and all technical is better than the performance index of modified Teflon plate and ultra-high molecular weight polyethylene board.For highway, the reduction of railroad bridge pot bearing cost, the optimization of performance index provide selection.
