Abstract
The utility model relates to a bridge support, in particular to a box beam cross-river support. The box beam cross-river support mainly solves the technical problems existed in the prior art that the structure of a box beam support is more complex, the installation is more inconvenient, the manufacturing cost is higher and the like. The box beam cross-river support comprises more than two steel pipe columns (1), and is characterized in that two Bailey capping beams (3) are fixed at the upper end of each steel pipe column (1) through a steel cover plate (2); and a Bailey truss lower chord (4) is erected at the upper ends of the Bailey capping beams.
Description
Technical field
The utility model relates to a kind of bridge support, especially relates to a kind of case girder span river course support.
Background technology
At present, along with the high speed development of Chinese national economy, the highway and railway construction also develops rapidly, and bridge erection then becomes the key project in the communications and transportation construction.Especially in middle river channel bridge pier construction works, many uses ponding water blockoff in the river course enters the korneforos with a large amount of earthwork heaps now, then carries out cofferdam construction after the compacting.Because the amount of banketing is large, the one, hindered the proper flow of streamflow, the 2nd, after engineering construction is finished, banket that it is unclean not remove or remove, cause river course flowing water or flood discharge not smooth, caused unnecessary disaster.Part unit in charge of construction is also arranged, adopt the metal bucket cofferdam, but this way is inadaptable to medium and small project, the technical requirement of underwater operation is high, and investment is large, is not easy to transportation and construction, is unfavorable for recycling, and therefore is not easy to promote.Chinese patent discloses a kind of steel box beam erection method (publication number: CN101078198) that is applied to self-anchored suspension bridge, the steps include: (1), on the coast or non-navigation region division steel box beam bracket on the steel box beam bracket, steel case beam to be carried out the pre-assembly unit of segmentation; (2), the steel case girder temporary pier that satisfies waterway classification is set in the river course that suspension bridge is crossed over; (3), pass forward with the method for pushing tow or the towing steel case beam that pre-assembly unit is good, steel case beam is moved on on the steel case girder temporary pier from the steel box beam bracket, utilize steel case girder temporary pier to support; Then continue the pre-jointing steel box beam of segmentation, successively incremeantal launching method or towing, good steel case beam is pushed ahead to make the pre-assembly unit of segmentation, successively by the steel case girder temporary pier on the river course, until arrive the opposite, river course on the bank; During the pre-jointing steel box beam of segmentation, be provided with to be convenient to the steel case beam front launching nose of steel case beam and steel case girder temporary pier overlap joint at the front end of steel case beam.But the structure of this box beam bracket is comparatively complicated, and comparatively inconvenience is installed, and manufacturing cost is higher.
The utility model content
The utility model provides a kind of case girder span river course support, and it mainly is that to solve the structure of the existing box beam bracket of prior art comparatively complicated, install comparatively inconvenient, the technical problem that manufacturing cost is more high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of case girder span of the present utility model river course support comprises the steel pipe column more than 2, and described every steel pipe column upper end is fixed with 2 shellfish thunder bent caps by steel deck-plate, and shellfish thunder bent cap upper end frame is provided with the Bailey truss lower chord.The diameter of steel pipe column can be for about 800mm, and the spacing between the adjacent steel tubing string is about 1700mm.Steel deck-plate can with shellfish thunder bent cap, steel pipe column by being welded and fixed.
As preferably, be fixed with the channel-section steel bridging between described adjacent 2 steel pipe columns.The channel-section steel bridging can be strengthened the intensity between adjacent 2 steel pipe columns.
As preferably, be fixed with the channel-section steel bridging between described adjacent 2 pairs of shellfish thunder bent caps.The channel-section steel bridging can be strengthened the intensity between adjacent 2 pairs of shellfish thunder bent caps.
As preferably, be provided with rubber cushion blocks between described shellfish thunder bent cap upper end and the Bailey truss lower chord.Rubber cushion blocks can play the effect of buffering, prevents that the Bailey truss lower chord is given a shock rear bump shellfish thunder bent cap upper end.
As preferably, be fixed with the steel plate reinforcing rib between described steel deck-plate and the steel pipe column.The steel plate reinforcing rib can be strengthened the intensity between steel deck-plate and the steel pipe column.
Therefore, the structure of the utility model box beam bracket is comparatively simple, reasonable, and it is comparatively convenient to install, and manufacturing cost is lower.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering among the figure: steel pipe column 1, steel deck-plate 2, shellfish thunder bent cap 3, Bailey truss lower chord 4, channel-section steel bridging 5, rubber cushion blocks 6, steel plate reinforcing rib 7.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of case girder span river course support of this example, such as Fig. 1, comprise the steel pipe column 1 more than 2, be fixed with channel-section steel bridging 5 between adjacent two steel pipe columns.Every steel pipe column 1 upper end is fixed with 2 shellfish thunder bent caps 3 by steel deck-plate 2, is fixed with steel plate reinforcing rib 7 between steel deck-plate and the steel pipe column.Be fixed with channel-section steel bridging 5 between adjacent 2 pairs of shellfish thunder bent caps.Shellfish thunder bent cap upper end frame is provided with Bailey truss lower chord 4.Be provided with rubber cushion blocks 6 between shellfish thunder bent cap upper end and the Bailey truss lower chord.
During use, steel pipe column 1, shellfish thunder bent cap 3, channel-section steel bridging 5, steel plate reinforcing rib 7 are welded together fixing getting final product.
The above only is specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
