Abstract
The invention discloses a compound steel tube concrete pier especially used in the mountain bridge pier. Two ends of the longitudinal supporting system are connected with the bridge girder and the bearing stage, which includes at least one supporting unit including at least four steel tube concrete columns set in crossly or horizontally to form the grid composing column with the supporting components. The invention uses the concrete grid column as the bridge, so it can simplify the pier structure and decrease the cost, the constructing difficulty and accelerate the construction progress.
Description
Technical field
The present invention relates to bridge, particularly a kind of steel-pipe concrete assembled pier.
Background technology
Along with socio-economic development, speedway extends to the mountain area.Differ greatly with the bridge pier height on the general beam bridge beam on the mountainous area highway, and high pier height is very high, how safe, build up mountain area Bridge High-pier, particularly complicated geology, Bridge High-pier that earthquake intensity is high economically, be the problem that the designer is concerned about.
At present, the superelevation bridge pier that adopts mainly contains following several form of structure usually: hollow pier, hollow pair of Thin-Wall Piers, hollow and two thin pier combination piers.When bridge pier height during greater than 60 meters, the bridge pier of these three kinds of form of structure exists technical requirements height, less economical deficiency, 200 meters of common spans, high 157 meters continuous rigid frame bridge pier, and it builds the peace expense at least more than 4,000 ten thousand yuan.Therefore, the bridge pier of a kind of facility of constructing, good economy performance if can be designed and provide, the development that mountainous area highway is built will be helped accelerating.
In recent years a kind of concrete filled steel tube lattice pier occurred, promptly be perfused with concrete steel pipe column and be disposed on the cushion cap along the vertical and horizontal of bridge by four, and between have horizontal beam and raker beam is formed lattice column.This lattice pier is convenient to construction and is helped reducing the bridge cost, and obtained application in the construction of some bridges because structure is comparatively simple.But since rigidity a little less than, as Bridge High-pier, can't overcome with existing that its flexibility is big, the antidetonation displacement surpasses a difficult problem that requires.
Summary of the invention
Technical problem to be solved by this invention provides the steel-pipe concrete assembled pier of a kind of facility of constructing, good economy performance, and it is especially suitable for use as the mountain area Bridge High-pier.
The technical solution adopted for the present invention to solve the technical problems is: steel-pipe concrete assembled pier of the present invention, fixedly connected with girder, the cushion cap of bridge respectively in the two ends of its longitudinal bracing system, this longitudinal bracing system comprises at least one support unit, support unit comprises at least four steel core concrete columns that are provided with at interval along the bridge vertical and horizontal, and, it is characterized in that: be fixedly connected with the steel concrete web between adjacent two steel core concrete columns by fixedly connected with it supporting member formation lattice column.
As the optimization to above-mentioned preferred version, described supporting member is included in longitudinal bracing and fastens the steel concrete dividing plate of fixedlying connected with each steel core concrete column that is provided with at interval along its vertical equity.
The invention has the beneficial effects as follows, with the concrete filled steel tube lattice column is the longitudinal bracing system of bridge, satisfies in intensity under the prerequisite of standard, and bridge pier structure is simplified, and can reduce the bridge cost greatly and reduce difficulty of construction effectively, and help accelerating the bridge construction process.
Steel-pipe concrete assembled pier of the present invention is especially suitable for use as the high pier of mountain area bridge.

The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
See figures.1.and.2, steel-pipe concrete assembled pier of the present invention, its longitudinal bracing are to fixedly connected with girder 10, the cushion cap 11 of bridge respectively in 20 two ends.Described longitudinal bracing is 20 to comprise at least one support unit, and support unit is made of at least four steel core concrete columns that are provided with at interval along the bridge vertical and horizontal, connects as one with supporting member between adjacent two steel core concrete columns.For improving described support unit bulk strength and rigidity, described longitudinal bracing is on 20, is fixedly connected with steel concrete web 50 between adjacent two steel core concrete columns.Be to improve the stability of bridge pier, described steel core concrete column along bridge to by 50～100: 1 puts the slope.The present invention with concrete filled steel tube lattice column and steel concrete web in conjunction with the longitudinal bracing as bridge is, satisfy in intensity under the prerequisite of standard, bridge pier structure is simplified, can be reduced the bridge cost greatly and reduce difficulty of construction effectively, help accelerating the bridge construction process.Steel-pipe concrete assembled pier of the present invention is especially suitable for use as the high pier of mountain area bridge.
With reference to Fig. 2 and Fig. 4, it is the steel concrete dividing plate 30 of fixedlying connected with each steel core concrete column that its vertical equity of 20 upper edges is provided with at interval that described supporting member is included in longitudinal bracing.With reference to Fig. 6, described supporting member also comprises stull member 40 and the diagonal supporting member made from shaped steel 60, for the appearance and modeling that makes bridge pier more attractive in appearance, described diagonal supporting member 60 can be embedded in the steel concrete web 50, and described steel concrete dividing plate 30 overlaps with the position of stull member 40, for improving the rigidity of lattice column, can apply prestressing force to it by the prestressed strand that is embedded in the steel concrete dividing plate 30.For improving the antiseptic property and the rigidity of described each steel core concrete column, stull member 40, with reference to Fig. 7, Fig. 8 and Fig. 9, be coated with steel concrete coating 25 on the outer wall of described each steel core concrete column, stull member 40, be distributed with the shear bar 26 that stretches in the steel concrete coating 25 on the outer wall of described each steel core concrete column, stull member 40.
