Abstract
The utility model discloses a girder steel bridge supported by a slide block. The girder steel bridge comprises a bridge abutment and a pier, wherein the top parts of the bridge abutment and the pier are grooves shaped like a Chinese character 'AO'; a steel bridge is arranged in each groove shaped like the Chinese character 'AO' of the bridge abutment and the pier; a rail is arranged at the bottom part of each groove shaped like the Chinese character 'AO' of the bridge abutment and the pier; a support seat plate is arranged on the rail; a high-strength self-lubricating composite material slide block corresponding to the position of the support seat plate is arranged at the bottom part of the steel bridge, and the slide block correspondingly contacts the support seat plate. The supporting part of the bridge, disclosed by the utility model, is a steel structure, is light in weight, high in bearing strength, small in shrinkage distortion of adapting with effect of temperature change, and high in manufacturing and installation accuracy, and can be produced and manufactured in a factory. The girder steel bridge can effectively prevent the girder bridge from slipping, has the advantages of being low in friction and free of maintenance, can better achieve axial displacement caused by temperature change, can be suitable for a long-span girder bridge, and can adapt with deformation caused by temperature and foundation settlement change, so that the steel bridge can adapt with small-displacement change.
Description
Technical field
The utility model relates to a kind of bridge construction structure, especially a kind of beam type steel bridge of thrust slide supporting.
Background technology
At present; Beam bridge is one of current more common a kind of bridge pattern, and the general concrete beam that adopts of tradition is bearing on abutment and the bridge pier, and this kind pattern exists concrete beam from great and to be prone to the temperature influence shrinkage strain when building big; Supporting place is big along bridge axes direction frictional resistance; Be difficult to realize the axial displacement that causes by variations in temperature,, generally only be applicable to middle or small bridge of striding the footpath therefore to pressure on foundation and to adapt to the performance requirement of sedimentation high.
Summary of the invention
The purpose of the utility model is: a kind of beam type steel bridge of thrust slide supporting is provided, and it can effectively prevent the beam bridge slippage, can better realize the axial displacement that caused by variations in temperature, is applicable to stride the big bridge in footpath, to overcome the deficiency of prior art.
The utility model is achieved in that the beam type steel bridge of thrust slide supporting, comprises abutment, bridge pier; The top of abutment and bridge pier is " recessed " font groove; In " recessed " font groove of abutment and bridge pier, be provided with the steel bridge beam, be provided with track, be provided with the supporting seat board in orbit in the bottom of " recessed " font groove of abutment and bridge pier; Be provided with the slide block corresponding in the bottom of steel bridge beam, slide block and the corresponding contact of supporting seat board with the supporting base Board position.
Inboard at " recessed " font groove is provided with freely-supported side wheel track, is provided with the freely-supported side wheel corresponding with freely-supported side wheel orbital position in the both sides of steel bridge beam.
Two ends at the supporting seat board are provided with positive stop, and anti-limited slip block breaks away from the supporting seat board.
Top at the steel bridge beam is provided with checkered steel plate, can prevent vehicle slip.
Slide block is the strnegth self-lubricating composite material for high slide block, has low friction, non-maintaining advantage.
The steel bridge beam is real abdomen formula " worker " word girder steel, is welded as a whole through junction plate between " worker " word girder steel, and its stud bolt hole is a slotted hole.But adaptive temperature and foundation settlement change the distortion that causes, make steel bridge can adapt to little change in displacement.
Because adopt above-mentioned technical scheme, compared with prior art, the bridge bearing of the utility model be a steel work partly, have from heavy and light, bearing strength shrinkage strain high, the adaptive temperature variable effect for a short time, can in factory, produce, make, the installation accuracy height; Abutment and bridge pier top are " recessed " type groove, effectively prevent the beam bridge slippage; The steel bridge bottom supporting is for adopting the slide block of strnegth self-lubricating composite material for high, has low friction, non-maintaining advantage, can better realize the axial displacement that caused by variations in temperature, applicable to striding the footpath beam bridge greatly; Stainless steel supporting seat board is established at the supporting track top, good antirust property, and friction factor is little, an end block of limiting, effectively anti-limited slip block de-orbits; The stud bolt hole of end real abdomen formula " worker " font girder steel is a slotted hole, but adaptive temperature and foundation settlement change the distortion that causes, make steel bridge can adapt to little change in displacement.The utility model is simple in structure, and is with low cost, and result of use is desirable.
