The pressure bearing support seat for the bridge extending and retracting device has the advantages that the structure is simple, higher carrying capability, good shock absorption effects and good anti-fatigue capacity are realized, the service life is long, the pressure bearing support seat is suitable for being popularized, and the installation and the replacement are very convenient.
Description
Technical field
The utility model relates to a kind of bridge technology field, particularly a kind of bridge extension joint pressure-bearing bearing.
Background technology
The pressure-bearing bearing is a flexible member important in the bridge extension joint, mainly plays a part carrying, damping noise reduction.The existing conventional rubber pressure-bearing bearing that uses, generally be which floor rubber is molded over and makes with the after cure that is superimposed with each other of which floor steel plate, rubber pressure-bearing bearing as shown in Figure 1, mainly be that metal dimple and the protruding seat of metal that cooperatively interacts is set on the bearing sliding layer, between the protruding seat of metal dimple and metal and all use the bonding parcel of rubber around the pressure-bearing bearing, play the effect of damping and buffering, this pressure-bearing bearing is if will improve supporting capacity, it is quite thin that rubber layer must design, but influence damping capacity, make the damping capacity deficiency.And under long-term pressurized situation, rubber and metal abutting edge are destroyed easily, problems such as metal exposes occur.The interstitial hole of pressure-bearing bearing top is circular locating hole, it is mainly used in and cooperates with the positioning convex rod of linkage and position, the height that product must be mentioned hole depth during replacing could take out, relatively more difficult, and the locate mode of its original point is not very reliable, rotating appears in product easily, causes bearing area to diminish.In heavy duty nowadays, under the highdensity traffic pressure, its carrying of existing neoprene bearing, damping capacity lost efficacy very fast, can not finely satisfy long-term instructions for use, simultaneously the bonding unfavorable factor that restricts its application life that also becomes of rubber and steel plate.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, a kind of simple in structure, bridge extension joint pressure-bearing bearing with big supporting capacity, good damping effect and good fatigue resistance is provided, this pressure-bearing bearing long service life is fit to promote.
The technical solution adopted in the utility model is as follows:
Bridge extension joint of the present utility model pressure-bearing bearing comprises sliding layer, and described sliding layer is provided with elastic layer.
Owing to adopted said structure, elastic layer is set on sliding layer, elastic layer has good pressure-bearing effect, is used for damping, has good damping effect.
Bridge extension joint of the present utility model pressure-bearing bearing is provided with and is fixedly connected with the rigid support layer between described sliding layer and the elastic layer.
Owing to adopted said structure, between sliding layer and elastic layer, be fixedly connected with the rigid support layer, satisfy the transition between sliding layer and the elastic layer, make that the supporting capacity of whole pressure-bearing bearing is good, and damping effect is good, long service life.
Bridge extension joint of the present utility model pressure-bearing bearing, the periphery of described elastic layer is provided with confinement ring.
Owing to adopted said structure, confinement ring to be used for installing and fixing this pressure-bearing bearing, and confinement ring can play position-limiting action, also can retrain elastic body, improves the effect of its supporting capacity.
Bridge extension joint of the present utility model pressure-bearing bearing, described confinement ring are quadrilateral frame shape structure, and described confinement ring has active edges.
Because having adopted said structure, confinement ring is quadrangle, wherein three limits are fixed, on one side movable, making things convenient for the installation and the replacing of bearing, confinement ring can play position-limiting action simultaneously, also can retrain elastic body, improves the effect of its supporting capacity.
Bridge extension joint of the present utility model pressure-bearing bearing, the active edges of described confinement ring is provided with fastening bolt.
Owing to adopted said structure, in use, confinement ring is connected with corresponding device thereof earlier, again pressure-bearing bearing elasticity aspect is put into confinement ring and gets final product, and convenience very is installed.
Bridge extension joint of the present utility model pressure-bearing bearing, described elastic layer is made by polyurethane, forms the elastic polyurethane layer.
Owing to adopted above-mentioned elastic layer, adopt polyurethane to make, make the anti-environmental aging function admirable of this elastic layer, damping performance is good, satisfies the long-term requirement of using.
Bridge extension joint of the present utility model pressure-bearing bearing, described rigid support layer is made by resin material.
Owing to adopted the rigid support layer, the resin high-strength light is realized the mild transition between sliding layer and the elastic layer, makes this pressure-bearing bearing have good supporting capacity and damping effect, and long service life more can satisfy engineering and use.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1. bridge extension joint pressure-bearing bearing of the present utility model, simple in structure, have big supporting capacity, have good damping effect;
2. bridge extension joint pressure-bearing bearing of the present utility model has good fatigue resistance, and long service life is fit to promote;
3. convenience is very installed and changed to bridge extension joint pressure-bearing bearing of the present utility model.
