Abstract
The utility model provides anti-falling beam support which comprises a support core body, wherein an upper connecting steel plate and a lower connecting steel plate. An anti-falling device is connected between the upper connecting steel plate and the lower connecting steel plate, one end of the anti-falling device is connected with the upper connecting steel plate, and the other end of the anti-falling device is connected with the lower connecting steel plate. The anti-falling device is an anchor chain, connecting ends are arranged at both ends of the anchor chain, and the anchor chain is connected with the connecting ends, gaskets and fasteners at both ends. The anti-falling device is a whole damping block which is formed by the anchor chain or rubber vulcanization so as to have enough strength and flexibility, and not affect damping performance of the support. When the support exceeds a support shear displacement limit or a horizontal displacement limit, the support is damaged, and a falling beam does not occur and serious consequences are not caused. Meanwhile, an anchor bolt of the support is directly used to connect, so that installation and replacement are convenient.
Description
Technical field
The utility model relates to the bearing that uses in a kind of bridge engineering, relates in particular to a kind of girder falling bearing.
Background technology
The bearing that uses in the bridge engineering comprises lead rubber bearing, unleaded shock insulation rubber bearing, horizontal force dispersing type bearing, common pot rubber bearing, antidetonation pot rubber bearing, common spherical bearing, quake-proof ball-shaped support, tension quake-proof ball-shaped support etc., above all kinds bearing generally all is to be connected with bridge beam body by upper junction steel plate, is connected with bridge pier by lower junction steel plate.
The bearing of this structure is not owing to there is anti-fall girder apparatus, thereby has the following disadvantages: when bearing was subject to surpassing the bearing shear displacemant limit or the horizontal movement limit, bearing was destroyed, can the fall serious consequence of beam of bridge superstructure.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of safe and reliable girder falling bearing, to overcome the existing deficiency of above-mentioned prior art.
The technical scheme that the utility model is taked is: a kind of girder falling bearing, comprise bearing core body and connected upper and lower junction steel plate, be connected with anti-slip device between the described upper and lower junction steel plate, described anti-slip device one end is connected with upper junction steel plate, and the other end is connected with lower junction steel plate.
Its further technical scheme is: described anti-slip device is anchor chain, and connection end is established at the two ends of anchor chain, and anchor chain is connected with upper and lower junction steel plate by connection end, pad and the securing member at two ends and is connected.
Its in addition further technical scheme is: described anti-slip device is snubber block, described snubber block forms an integral body by anchor chain and the vulcanization of rubber, the snubber block two ends are provided with the connection end that is connected with anchor chain, and snubber block is connected with upper and lower junction steel plate by connection end, pad and the securing member at two ends and is connected.
Described snubber block or be circular or be polygon.
Its further technical scheme be: described anchor chain or for iron chains or for electric welded anchor cable or for high strength cord.
Because adopt technique scheme, the girder falling bearing of the utility model has following beneficial effect:
1. the girder falling bearing of the utility model, be connected with anti-slip device between its upper and lower junction steel plate, when bearing is subject to surpassing the bearing shear displacemant limit or the horizontal movement limit, bearing is destroyed, bridge superstructure is being lifted by the anti-slip device that is connected with bridge pier, and the beam that can not fall causes serious consequence.
2. the anti-slip device that adopts of the girder falling bearing of the utility model, the snubber block that is formed by anchor chain or anchor chain and the vulcanization of rubber consists of, anchor chain or be iron chains or for electric welded anchor cable or for high strength cord, thereby guarantee that it had both had enough intensity, has again certain flexibility, the unlikely shockproof properties that affects bearing.
3. the anti-slip device of the girder falling bearing of the utility model employing can directly utilize the anchor bolt of bearing to connect, and installation and replacing are all very convenient.
Be further described below in conjunction with the technical characterictic of drawings and Examples to the girder falling bearing of the utility model.
