Description
Technical field
The utility model relates to a kind of highway bridge buffer.
Background technology
To seriously intercept the lifeline of leading to disaster area after being damaged in earthquake as the bridge engineering of important transport hub, affect the promptness of the disaster relief, and bring great inconvenience to the disaster relief and post-disaster reconstruction.Meanwhile, bridge is also the infrastructure in daily life, and its distribution is wide, and public character is strong, and applicability and safety ensure that it provides precondition easily for people.China is as one of multiple country of earthquake, and the anti-seismic performance of bridge just becomes a part very important in bridge design.Rationally effective seismic measures is taked normally energy-dissipating device to be set between girder and bridge pier or bridge tower for bridge, ensure due to variations in temperature or shrinkage and creep etc. be out of shape at a slow speed under can not to bridge pier or bridge tower generation larger additional internal force when, reach the effect of energy-eliminating shock-absorbing.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides that a kind of structure is simple, the highway bridge buffer of good damping effect, long service life.
Described object is achieved by the following scheme: a kind of highway bridge buffer, comprise quadrangle box, the upper end of box body is hatch frame, the four sides inwall of described box body is longitudinally provided with chute, slide block is inlaid with in described chute, also comprise top board, the edge of described top board is fixedly connected with slide block, upper surface in described box body and the soffit of top board are equipped with fixed block, described fixed block is provided with groove, be provided with disc spring in described groove, described disc spring inner sleeve has support column, and the bottom of described support column is arranged in groove.One end of described top board is provided with swallowtail-shaped slide, swallow-tail form slide block is inlaid with in described swallowtail-shaped slide, the described top of swallow-tail form slide block and the other end of top board are equipped with column, the top of two columns is equipped with semicircle fixed block, retreat stop block in described swallowtail-shaped slide, the described retreat stop block position corresponding with on the sidewall of swallowtail-shaped slide is provided with pin-and-hole, is provided with pin in described pin-and-hole.
Described box body is that metal material is made.
The utility model has the following advantages: the utility model effectively can reduce the impact force of bridge construction abutment and girder under geological process, has good protective effect to bridge construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1-box body, 2-chute, 3-slide block, 4-top board, 5-fixed block, 6-groove, 7-disc spring, 8-support column.15-swallowtail-shaped slide, 16-swallow-tail form slide block, 17-column, the semicircle fixed block of 18-, 19-retreat stop block, 20 pin-and-holes.
Detailed description of the invention
The utility model is elaborated preferred embodiment below in conjunction with accompanying drawing.
A kind of highway bridge buffer, comprise quadrangle box 1, the upper end of box body 1 is hatch frame, the four sides inwall of described box body 1 is longitudinally provided with chute 2, slide block 3 is inlaid with in described chute 2, also comprise top board 4, the edge of described top board 4 is fixedly connected with slide block 3, upper surface in described box body 1 and the soffit of top board 4 are equipped with fixed block 5, described fixed block 5 is provided with groove 6, disc spring 7 is provided with in described groove 6, described disc spring 7 inner sleeve has support column 8, the bottom of described support column 8 is arranged in groove 6, one end of described top board 4 is provided with swallowtail-shaped slide 15, swallow-tail form slide block 16 is inlaid with in described swallowtail-shaped slide 15, the top of described swallow-tail form slide block 16 and the other end of top board 4 are equipped with column 17, the top of two columns 17 is equipped with semicircle fixed block 18, retreat stop block 19 in described swallowtail-shaped slide 15, described retreat stop block 19 position corresponding with on the sidewall of swallowtail-shaped slide 15 is provided with pin-and-hole 20, pin is provided with in described pin-and-hole.Described box body 1 is made for metal material.
Box body 1 is arranged on abutment, the bottom of the load-bearing pillar below girder is arranged on the top plate 4, slided in swallowtail-shaped slide 15 by swallow-tail form slide block 16, a wherein root post 17 is moved, and now one of them semicircle fixed block 18 is drawn close, after being blocked by load-bearing pillar to another semicircle fixed block 18, pin is inserted in pin-and-hole 20, retreat stop block 19 is fixed with swallowtail-shaped slide 15, prevents the column 17 on swallow-tail form slide block 16 from moving, easy for installation while effective guarantee girder is stable.Play cushioning effect by the flexible of disc spring 7, slide block 3 slides in chute 2, avoids dislocation and the inclination of top board 4, ensure the firm of girder, the height of support column 8 is less than the height of disc spring 7, when girder vibrations are excessive, supported by support column 8 pairs of top boards 4, prevent the inclination of girder.
Present embodiment does not just limit its protection domain to the exemplary illustrated of this patent; those skilled in the art can also carry out local to it and change; as long as no the Spirit Essence exceeding this patent, be all considered as the equivalent replacement to this patent, all at the protection domain of this patent.
