Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1-4, the support structure of the assembled viaduct bent cap of the utility model comprises a bracket main body and a support piece arranged on the bracket main body and used for bearing the bent cap, wherein the bracket main body is sequentially divided into a standard section 1, an adjusting section 2 and a fixing section 3 from bottom to top, and the sections are connected through a flange 4; a concrete foundation pier 5 is arranged between the bottom of the standard section 1 and the ground, and the concrete foundation pier 5 comprises a yellow sand layer 51 at the bottom, a concrete layer 52 above the yellow sand layer 51 and a concrete surrounding edge 53 surrounding the edge of the Huang Shaceng; the support at the top of the fixed section 3 is a hydraulic jack 6.
Compared with the traditional integral steel pipe frame or a scaffold erected by a plurality of thin steel pipes, the whole bracket main body is divided into a three-section structure, the standard section 1 and the fixed section 3 are both standard heights, the adjusting section 2 can be provided with a plurality of models with different heights according to actual conditions particularly according to the height difference of the viaduct and the telescopic height of the hydraulic jack 6 according to comprehensive consideration of the height of the viaduct and the transportation of vehicles. At present, the bent cap is generally installed one by one, so that the standard section 1 and the fixed section 3 can be repeatedly recycled, and the turnover utilization rate is improved by only reasonably selecting the adjusting section 2. For the support piece, a sand cylinder structure is generally adopted at present, but the sand cylinder can only be adjusted downwards, if the actual elevation is lower than the designed elevation, the sand cylinder is difficult to adjust in place, therefore, the hydraulic jack 6 is adopted as the support piece, the support height can be flexibly adjusted, and the requirement on the installation precision of the support main body is reduced. In addition, by providing the concrete pier 5 having the yellow sand layer 51 at the bottom thereof on the ground, the flatness of the foundation can be ensured, and the elevation of the bracket main body can be controlled more easily.
In a specific construction process, as shown in fig. 4, the position of the concrete foundation pier 5 is determined according to the installation position of the capping beam 7, when the concrete foundation pier 5 is constructed, as shown in fig. 3, a layer of yellow sand layer 51 is paved on the ground, the top of the yellow sand layer 51 is flattened through leveling equipment, then a template is erected, a concrete layer 52 is poured on the top of the yellow sand layer 51, so that the top of the concrete foundation pier 5 is flattened, and finally, in order to ensure the stability of the concrete foundation pier 5, a layer of concrete surrounding edge 53 is required to be poured on the yellow sand layer 51. After the concrete foundation pier 5 is solidified, a standard section 1, an adjusting section 2, a fixing section 3 and a hydraulic jack 6 can be erected above one side of the concrete foundation pier. And finally, hoisting the bent cap 7, enabling the middle part of the bent cap to be lapped on the upright post 8, and supporting both ends of the bent cap 7 by adjusting the hydraulic jack 6.
When the concrete foundation pier 5 is constructed, in order to play a stable leveling role, the thickness of the yellow sand layer 51 should be not less than 200mm, in order to ensure the supporting strength, the height of the whole concrete foundation pier 5 should be not less than 400mm, and in order to facilitate the subsequent installation of the bracket main body, an embedded steel plate 54 for fixing the standard section 1 is arranged at the top of the concrete foundation pier 5.
For the structure of the bracket main body, the utility model adopts the scheme that the standard section 1 and the adjusting section 2 are composed of four support columns 11 and diagonal braces 12 connected between the support columns 11, and flanges 4 are arranged at the upper end and the lower end of each support column 11. Specifically, the support column 11 is a seamless steel pipe with phi 219×6, and the diagonal brace 12 is a seamless steel pipe with phi 133×4. The seamless steel pipe with the model can ensure the strength requirement of the support, and meanwhile, the resource waste caused by transition design can be avoided.
For the fixed section 3, for simplifying the structure, the fixed section 3 includes three H shaped steel 31, and wherein two H shaped steel 31 parallel arrangement, another H shaped steel 31 set up the middle part in two H shaped steel 31 top perpendicularly, and two H shaped steel 31 below is equipped with four landing legs 32, and the landing leg 32 bottom is equipped with the flange 4 that links to each other with the support column 11 of regulating section 2.
In order to ensure the stability of the support, the hydraulic jack 6 should include two hydraulic jacks 6 because the support end area of the hydraulic jack 6 is small, and the hydraulic jacks are arranged above the H-shaped steel 31 at the top of the fixed section 3 at intervals to ensure the stability of the support.
