Abstract
The utility model relates to a supporting and limiting integrated structure for steel box girder installation, which comprises a steel box girder installation support, wherein temporary supports are arranged on two sides of the top of the support at certain intervals along the longitudinal direction of the support, the bottom of each temporary support is welded with a bearing beam at the top of the support, a horizontal supporting surface is arranged at the top of each temporary support towards one side of the inner side of the support, and a limiting block higher than the supporting surface is arranged at the top of each temporary support towards one side of the outer side of the support; the bottom of the steel box girder is supported on the supporting surface at the top of the temporary support, and the side wall of the steel box girder is tightly attached to the limiting block at the top of the temporary support. The utility model discloses when the installation of steel case roof beam, the vertical braces and the spacing completion of level that enable the steel case roof beam effectively improve steel case roof beam installation efficiency of construction.
Description
Technical Field
The utility model belongs to the technical field of steel construction bridge construction, support and spacing structure to the steel box roof beam when relating to the installation of steel box roof beam.
Background
In the construction process of steel structure bridges on land, a floor support splicing method is usually adopted for mounting the steel box girders, and the sections of the steel box girders are hoisted on the supports by using a crane and are sequentially welded with each other. Because the support can have certain inelastic deformation, the top surfaces of the adjacent steel box girder segments are uneven, and therefore a temporary support needs to be arranged at the top of the support to adjust the elevation of the steel box girder; meanwhile, the crane swings to a certain extent when the steel box girder is hoisted and placed, the ends of the adjacent steel box girders are not aligned left and right, the steel box girders are required to be transversely adjusted, and the process is complex and is not beneficial to accelerating the construction progress.
Disclosure of Invention
The utility model aims at the above problem, a support and spacing integrated structure for steel case roof beam installation is provided, steel case roof beam installation efficiency of construction is improved.
The technical scheme of the utility model as follows:
the utility model provides a support and spacing integrated structure for installation of steel box girder, includes steel box girder installing support, its characterized in that: the support is characterized in that temporary supports are arranged on two sides of the top of the support at intervals along the longitudinal direction of the support, the bottom of each temporary support is welded with a bearing beam at the top of the support, a horizontal supporting surface is arranged on one side, facing the inner side of the support, of the top of each temporary support, and a limiting block higher than the supporting surface is arranged on one side, facing the outer side of the support, of the top of each temporary support; the bottom of the steel box girder is supported on the supporting surface at the top of the temporary support, and the side wall of the steel box girder is tightly attached to the limiting block at the top of the temporary support.
The utility model discloses a take horizontal limit function's temporary support, the support adopts the steel pipe preparation, and material cost is low, and simple structure enables the vertical braces and the spacing completion of level of steel box girder, effectively improves steel box girder installation efficiency of construction.

FIG. 2 is a schematic elevational view of one embodiment of a temporary support;
FIG. 3 is a schematic plan view of an embodiment of a temporary support.
Detailed Description
As shown in fig. 1, the utility model comprises a steel box girder mounting bracket 1, wherein temporary supports 2 are arranged on both sides of the top of the bracket at regular intervals along the longitudinal direction of the bracket, the bottom of each temporary support 2 is welded with a bearing beam on the top of the bracket, a horizontal supporting surface 21 is arranged on one side of the top of each temporary support facing the inner side of the bracket, and a limit block 22 higher than the supporting surface is arranged on one side of the top of each temporary support facing the outer side of the bracket; the bottom of the steel box girder 3 is supported on a supporting surface 21 at the top of the temporary support, and the side wall of the steel box girder 3 is tightly attached to a limiting block 22 at the top of the temporary support.
As shown in fig. 2 and 3, in the embodiment of the present invention, the temporary support 2 can be made of a steel pipe with a certain height, and the height of the steel pipe should be not less than 50cm, so that a jack can be conveniently arranged between the top of the support and the bottom of the steel box girder to adjust the elevation of the steel box girder; longitudinally cutting the upper end of the steel pipe for a certain length, transversely cutting off the pipe wall on one side, and welding a horizontal panel at the cutting position to serve as a supporting surface 21 of the steel box girder; the pipe wall at the other side is reserved as a limiting block 22, and at least two stiffening plates 23 which are horizontally arranged are welded on the inner wall of the reserved pipe wall.
The utility model discloses a temporary support welds on the support in advance, and the interval of spacing piece equals the width of steel case roof beam on the relative temporary support in support both sides. When the steel box girder is hoisted and placed on the support, the steel box girder is placed down along the space between the temporary support limiting blocks on the two sides, and the left and right alignment of the end parts of the adjacent steel box girders can be ensured; the jack can be arranged at the bottom of the steel box girder to adjust the elevation of the steel box girder so that the top surfaces of the adjacent steel box girders are flush.
