Description
Technical field:
The utility model relates to the bridge apparatus field, specifically a kind of stretching device that can move and keep the indeformable shatter-proof buffer-type bridge of bridge when earthquake takes place to X, Y, Z-direction.
Background technology:
Usually, the long bridge of length with most abutments, for the expansion of dealing with the bridge that causes because of variations in temperature is shunk, the bridge upper plate can be divided into multistage by certain length, be provided with flexible linkage between the segmentation, existing flexible linkage generally adopts the finger-type structure, cutting apart place's upper plate at bridge or viaduct is connected the mode with the interlock that interlocks mutually with upper plate, the retractility of this structure can only adapt to bridge and expand with heat and contract with cold with variation of temperature, its deficiency is: when earthquake takes place, the direction movement that bridge can only be advanced along vehicle, because the effect of earthquake, the direction that relative vehicle is advanced, its left and right horizontal direction and above-below direction at all can't movements, because and the flexible linkage that bridge connects together is fixed, when laterally being moved, cause the fixing flexible destroyed generation of linkage space, in this space, flow into rainwater, drainage takes place, finger position down hangs low or fractures, safety that can influence driving, and the life-span that shortens bridge cause facility such as bridge to be damaged, cause very big influence to vehicle pass-through.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, can move to X, Y, Z axle when providing a kind of earthquake to take place, prevent flexible linkage and bridge from connecting together and make the stretching device of the shatter-proof buffer-type bridge that its structure, road damaged, vehicle be obstructed.
The utility model can reach by following measure:
A kind of stretching device of shatter-proof buffer-type bridge, be provided with upper plate, it is characterized in that upper plate is by flexible connecting portion body, flexible buffer body constitutes, flexible connecting portion body is to rely on cylindrical hinge axial region that hinge axis fixes and its hinge axial region with integrally formed plate shaped steel plate portion to constitute, and, the side of steel plate portion, connect the flexible connecting portion body of adjacent unit, formation makes flexible connecting portion be inserted into the cone pulley slot part that bolt is concluded with the union piece of one movement, on its slot part with connection fittings insert with the slot part band abundant every secondary material of sheet rubber or the secondary material of iron plate conclude with bolt, the flexible connecting portion body of several adjacent units is connected to each other, flexible connecting portion body is made with iron and steel material quality, flexible buffer body is connected the steel plate portion end of flexible connecting portion body, accommodate flexible connecting portion body according to the telescopic action of variations in temperature and the X that takes place according to earthquake, Y, the movement of Z-direction, flexible buffer body is formed for the continuous wrinkle shape structure that the steel plate portion movement of accommodating telescopic action or cause because of earthquake has a plurality of hollows, between this wrinkle shape structure lower hollow, because of earthquake takes place, during steel plate portion movement, form the protruding wrinkle that prevents that flexible buffer body from raising up, flexible buffer body is made of the reinforcing rubber material.
Flexible connecting portion body hinge axis subordinate portion is provided with the hinge axial region and supports accessory in the utility model, with the bottom of flexible connecting portion body hinge axial region and lateral ring around support, and be fixed on the abutment, make the hinge axial region within it portion do the movement of hinge type circumference downwards freely.
The bottom of flexible buffer body is provided with the pars contractilis holding components in the utility model, and flexible buffer body is fixed through anchor shape bolt and pars contractilis holding components.
The shape of pars contractilis holding components can be made as the shape of cylindrical shape inner cylinder according to the radian of flexible buffer body in the utility model, make flexible buffer body one end not have compression or lax and in the same old way keep its form, when earthquake takes place, the movement of flexible connecting portion body is is freely come in and gone out.
The utility model since when adopting earthquake to take place to X, Y, Z axle 3 direction of principal axis structure movably all, wrinkle type structure and self material (rubber material) of band hollow play telescopic action according to characteristic, cause the movement of flexible connecting portion body to absorb and relax, can not cause big problem, the advantages such as application life that have rational in infrastructure, antidetonation, safety, high temperature resistant low temperature, prolong bridge to vehicle pass-through.
