Abstract
The utility model relates to a high-damping and isolating plate-type bridge bearing comprising an upper bearing plate, a lower bearing plate and a rubber plate-type bearing, wherein the rubber plate-type bearing is arranged in the middle between of the upper bearing plate and the lower bearing plate. The utility model is improved in that the surface of the rubber plate-type bearing corresponding to the upper bearing plate is evenly provided with friction bumps; two ends of the lower surface of the upper bearing plate are respectively and correspondingly provided with upper stop blocks; lower stop blocks are respectively and correspondingly arranged at two sides of the upper surface of the lower bearing plate; the rubber plate-type bearing is arranged between the lower stop blocks at the two sides; and the inner side surface of the upper stop block corresponding to the lower stop block is provided with a damping rubber belt. Through the anti-skid treatment on the upper surface of the rubber plate-type bearing, the friction force of the rubber plate-type bearing is improved during the vertical force acting process of the bridge; the separation of a bridge body and an abutment owing to overlarge horizontal displacement of the bearing under the action of the horizontal force can be effectively prevented through the upper stop blocks and the lower stop blocks; and the lateral displacement of the bridge can be effectively limited, thereby protecting the bridge body and the abutment under the influence of the earthquake.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of rubber bridge pad.
Background technology
The laminated rubber bearing that is used for highway, railroad bridge beam body below is widely used so that its damping characteristic is good, bearing capacity is high.But common laminated rubber bearing is to bear the function of vertical force, horizontal force mainly relies on frictional resistance to bear, usually have only about 15% of vertical force, in use produce bigger horizontal movement and destroy because of earthquake horizontal force, vehicular impact power easily.Behind the Wenchuan earthquake, engineering bound pair geological process is very deep to structural damage self-examination, and bearing must cause enough attention as the important antidetonation member of bridge.And common laminated rubber bearing is difficult to arrive the desired anti seismic efficiency of design because shortcoming is obvious in the high earthquake intensity district, and its structure must be improved.Existing antidetonation type bearing cost is high, is difficult to popularize in medium and small bridge use.
Summary of the invention
Easily produce the problem that displacement destroys in order to solve existing common laminated rubber bearing because of big horizontal force action, the utility model provides a kind of high damping to subtract the board-like bridge pad of shock insulation.
High damping subtracts the board-like bridge pad of shock insulation and comprises upper base plate, following seat board and the board-like bearing of rubber, and the board-like bearing of rubber is the middle part between upper base plate and following seat board, and the lateral surface of upper base plate and following seat board is laid with erection bolt respectively;
Upper base plate soffit two ends correspondence respectively are provided with block, and following seat board upper surface both sides correspondence respectively are provided with down block, and the board-like bearing of rubber is between the following block of both sides; The inboard table of the last block corresponding with following block is provided with the yielding rubber band; The board-like abutment surface of the rubber corresponding with upper base plate is laid with friction lug.
The described block of going up is aduncate arc piece with following block.
Described friction lug is the segment shape.
Useful technique effect of the present utility model embodies in the following areas:
1, the anti-skidding processing of carrying out owing to upper surface at the board-like bearing of rubber, can make laminated rubber bearing in the process of bridge vertical force, can not cause laminated rubber bearing to be subjected to displacement, thereby the high damping properties of laminated rubber bearing was lost efficacy because of frictional force is too little;
2, on described laminated rubber bearing, be provided with and laterally subtract shock insulation blend stop mechanism; it is excessive to prevent effectively that bearing from producing horizontal movement under the horizontal force action of seismic forces; cause beam body and pier to break away from; thisly subtract the lateral displacement that shock insulation blend stop mechanism can effectively limit bridge; thereby make bearing under the influence of earthquake, can protect the safety of beam body and pier.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the vertical view of Fig. 1,
Fig. 3 is the partial enlarged drawing at the board-like bearing of rubber place among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2, high damping subtracts the board-like bridge pad of shock insulation and comprises upper base plate 1, following seat board 4 and the board-like bearing 2 of rubber, the board-like bearing 2 of rubber is the middle part between upper base plate 1 and following seat board 4, and the lateral surface of upper base plate 1 and following seat board 4 is laid with erection bolt respectively.Upper base plate 1 soffit two ends correspondence respectively are provided with block 7, following seat board 4 upper surface both sides correspondence respectively are provided with down block 8, the board-like bearing 2 of rubber between the following block 8 of both sides, the mobile space when bearing gap between board-like bearing 2 of rubber and the following block 85 is subjected to radial effect power for the board-like bearing 2 of rubber; Last block 7 and following block 8 are aduncate arc piece, and last block 7 inner surfaces corresponding with following block 8 are provided with yielding rubber band 3, and the gap 6 between last block 7 and the following block 8 is the radially adjusting play between the two; Rubber board-like bearing 2 surfaces corresponding with upper base plate 1 are laid with friction lug 9, and friction lug 9 is the segment shape, sees Fig. 3.Last block and following block are aduncate arc piece.
During use, the upper base plate 1 that high damping subtracts the board-like bridge pad of shock insulation connects bridge beam body by erection bolt, and seat board 4 is connected on the bridge pier pier under it.
Operating principle of the present utility model is as follows:
The work purpose that high damping subtracts the board-like bridge pad of shock insulation is being passed on the pier of bottom the active force safety of bridge top beam body.The vertical force that bridge top beam body produces is passed to the board-like bearing 2 of rubber by upper base plate 1, is passed to down seat board 4 by the board-like bearing 2 of rubber again, is passed to bridge bottom pier at last again.The horizontal force that bridge top beam body produces is delivered to the bottom pier by the frictional force between upper base plate 1 and the board-like bearing 2 of rubber.Because the board-like bearing 2 of rubber has been set up friction lug 9, the horizontal force that makes this novel bearing to bear also strengthens greatly.When the horizontal force that produces when top beam body surpasses certain limit value (as bigger geological process), relative slip between upper base plate 1 and the board-like bearing 2 of rubber, the gap between last block 7 and the following block 8 reduces gradually, until contacting fully.Last block 7 is with after following block 8 contacts, rely on the intensity of block self can resist bigger horizontal force, instant impact when the existence of yielding rubber band 3 has simultaneously also cushioned the block contact, thereby the stressed safety of assurance bearing, and guarantee that bridge top beam body and pier do not break away from.
