Abstract
The utility model discloses a transverse bearing system beam bridge which comprises a plurality of foundation piles, pier columns arranged on the upper sides of the foundation piles and a bridge floor arranged on the upper sides of the pier columns. A capping beam body is longitudinally arranged among the pier columns and the bridge floor along the bridge floor, and the bridge floor comprises a plurality of transverse unit beams which are transversely arranged on the upper side of the capping beam body along the bridge floor. In the transverse bearing system beam bridge, the capping beam body is longitudinally arranged among the pier columns and the bridge floor along the bridge floor and positioned on the two sides of an existing barrier, the number of the pier columns and the span of the capping beam body can be adjusted freely according to the barrier below the bridge and the weight of the bridge floor, and thus headroom below the bridge or the ground is effectively saved. Meanwhile the transverse unit beams are transversely arranged on the upper side of the capping beam body along the bridge floor and directly bear live loads and self weight of the bridge floor, so that in comparison with a traditional capping beam which is arranged transversely and first bears longitudinal loads of the bridge floor, and the capacity spanning the barrier below the bridge or the ground is higher. The transverse bearing system beam bridge is used in the field of bridges.
Description
Technical field
The utility model is used for the bridge field, particularly relates to a kind of beam bridge.
Background technology
Bridge generally is divided into five big class, i.e. steelframe bridge, beam bridge, arch bridge, suspension bridge and composite bridges.Wherein beam bridge is generally built big, the more shallow place, waters of span in, is made up of bridge post and bridge plate, and weight of object passes to the bridge post from bridge plate, and as supporting member, girder can be solid web girder or girder truss based on the girder that is subjected to bend.The solid web girder simple structure is made, sets up and keep in repair all more convenient, is widely used in middle or small span bridge; The rod member of girder truss bears axial force, and material can make full use of, and it is lighter to conduct oneself with dignity, and span ability is big, is used for building Longspan Bridge more.
The conventional beam bridge of China mainly contains simply supported girder bridge, continuous girder bridge and continuous rigid frame bridge etc. at present, its typical mechanics feature is: beam body main stress direction is that bridge is vertical, generally be perpendicular to the river crossed over, road, mountain valley etc., and consistent with the automobile direct of travel, and bridge pier and bent cap main stress direction are bridge lateral.Under the normal condition, thisly transferring the pressure to force transfer system on pier stud and the basis by the vertical structure of directly bearing automobile by transversary, is a kind of most economical, rational structure system.When space under the bridge along the line (underground, ground or aerial) exists the restriction of wider range to arrange the space (as metro shield tunnel, sunk type road, existing viaduct and other underground buildings etc.) of bridge pier, the common employing of processing method of tradition beam bridge structure system is striden footpath bent cap or grade beam greatly as crossing over structure, bears beam body dead load, mobile load and the deadweight of striding in the scope of footpath by it.But because it is big to stride the footpath, cause the structure height and the yet corresponding increasing of bridge pier size of bent cap or grade beam, this beam bridge is not only not attractive in appearance, a little less than the span ability, and has taken under the bigger bridge or underground headroom.
The utility model content
For addressing the above problem, the utility model provides under a kind of overpass bridge or the underground obstacle ability is saved the beam bridge of under-clearance by force and effectively.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of lateral bearing system beam bridge, comprise some foundation piles, be located at the pier stud of foundation pile upside and be located at the bridge floor of pier stud upside, vertically be provided with the bent cap body along bridge floor between pier stud and bridge floor, bridge floor comprises some lateral cell beams that are horizontally installed on bent cap body upside along bridge floor.
Be further used as the improvement of technical solutions of the utility model, foundation pile is that each lateral cell beam all is crossed on the bent cap body of two row's foundation pile upsides along two vertically parallel rows of bridge floor.
Be further used as the improvement of technical solutions of the utility model, be equipped with bearing between each lateral cell beam and bent cap body.
Be further used as the improvement of technical solutions of the utility model, the lateral cell beam is steel case beam or T word concrete beam or box concrete beam or hollow slab beam.
Be further used as the improvement of technical solutions of the utility model, be equipped with the unit beam connection between each lateral cell beam.
Be further used as the improvement of technical solutions of the utility model, bridge floor also comprises the bridge floor layer that is located at lateral cell beam upside, and the bridge floor layer comprises concrete cast-in-situ layer, waterproofing course and the layer of mating formation from top to bottom successively.
The beneficial effects of the utility model: in this lateral bearing system beam bridge, the bent cap body vertically is located between pier stud and bridge floor along bridge floor, and be positioned at the both sides of existing obstruction, pier stud quantity and bent cap body are striden the footpath and can freely be adjusted according to obstruction under the bridge and bridge floor weight, it is following or underground headroom effectively to save bridge, bent cap body upside laterally is provided with the lateral cell beam along bridge floor simultaneously, the lateral cell beam directly bears bridge floor mobile load and deadweight, and the bent cap overpass bridge ability following or underground obstacle that more traditional lateral arrangement is born vertical bridge floor load earlier is stronger.
