Abstract
A kind of implicit expression door frame pier girder construction comprises bridge pier, cushion cap and pile foundation, and its structure is: on the upper surface of bridge pier, be fixed with bearing pad stone and bearing successively, and door frame pier crossbeam, across two bridge piers, is fixed on bearing, and longitudinal bridge beam body embeds door frame pier crossbeam.The utility model is inner by longitudinal beam body being arranged on door frame pier crossbeam, and bearing and bearing pad stone are set between door frame pier crossbeam and bridge pier, solve the problem of the setting position due to door frame pier crossbeam existed in prior art and the structure height produced increase on the one hand, solve the displacement because temperature effect makes longitudinal beam body produce and deformation on the other hand, affect the problem that bridge normally uses.
Description
Technical field
The utility model relates to a kind of pier girder construction of bridge, especially a kind of implicit expression door frame pier girder construction.
Background technology
Along with the fast development of Communications construction project, the situation that overpass intersects with existing road low-angle occurs repeatedly, but the overpass pier location newly built should not take existing road surface under bridge and weaken its traffic capacity, if road is wider under bridge, the angle of cut is very little, and the span of newly-built overpass can be made larger, deck-molding significantly increases, the newly-built circuit section of indulging is raised, and construction investment can significantly rise, and span bridge construction is very risky.If the newly-built overpass section of indulging elevation is controlled, large span beam bridge scheme is adopted to meet requirement of engineering even if sacrifice economic condition, the longitudinal beam body of conventional bridge is built on door frame pier crossbeam, occupy the building height above door frame pier crossbeam, add the whole height of bridge, when vertical elevation is by limited time, scheme can not engineering demands.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of implicit expression door frame pier girder construction, inner by longitudinal beam body being arranged on door frame pier crossbeam, and bearing and bearing pad stone are set between door frame pier crossbeam and bridge pier, solve the problem of the setting position due to longitudinal beam body existed in prior art and the bridge height produced increase on the one hand, solve on the other hand because temperature effect makes longitudinal beam body produce displacement and deformation, affect the problem that bridge normally uses.
To achieve these goals, the technical solution used in the present invention is: a kind of implicit expression door frame pier girder construction, comprise bridge pier, cushion cap and pile foundation, it is characterized in that: on the upper surface of bridge pier, be fixed with bearing pad stone and bearing successively, door frame pier crossbeam, across two bridge piers, is fixed on bearing, and the inside of door frame pier crossbeam is provided with longitudinal beam body.
Described door frame pier crossbeam with embed its inside longitudinal beam body be the overall structure of moulding by casting.
The beneficial effects of the utility model are: the utility model adopts said structure, solve the integral bridge height existed in prior art higher, inner by longitudinal beam body two ends being arranged on door frame pier crossbeam, and bearing is set between door frame pier crossbeam and bridge pier and supports pinner, effectively avoid existing ground level road, reduce vertical elevation to greatest extent, the bearing settlement under door frame pier crossbeam meets the change in displacement of longitudinal beam body under temperature effect.
Accompanying drawing explanation
Fig. 1: be the structural representation of existing Dun Liang.
Fig. 2: be structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Figure 1 shows that existing pier girder construction, wherein longitudinal beam body 6 is arranged on door frame pier crossbeam 7, adds the height of whole pontic, adds construction investment.For circuit elevation by limited time, scheme can not engineering demands.
Be illustrated in figure 2 structural representation of the present utility model, comprise bridge pier 1, cushion cap 2 and pile foundation 3, its structure is be fixed with bearing pad stone 4 and bearing 5 successively on the upper surface of bridge pier 1, door frame pier crossbeam 7 is across two bridge piers 1, be fixed on bearing 5, the inside of door frame pier crossbeam 7 is provided with longitudinal beam body 6.Door frame pier crossbeam 7 is the overall structure of moulding by casting with the longitudinal beam body 6 of its inside of embedding.Longitudinal beam body 6 is arranged on the inside of door frame pier crossbeam 7 by the utility model, while can realizing prior art needs, effectively avoids existing ground level road, reduces vertical elevation to greatest extent.Between door frame pier crossbeam 7 and bridge pier 1, be disposed with bearing 5 and bearing pad stone 4, door frame pier crossbeam 7 can be made to consume longitudinal beam body 6 due to the displacement that produces and deformation by variations in temperature, improve security performance and the application life of overall Dun Liang.
