Problems solved by technology
[0005] The purpose of the present invention is to solve the problem that the structural strength and rigidity conditions cannot be satisfied when only adopting I-beam or Bailey frame as the support bracket of the cover beam. The bracket system effectively shortens the length of the bracket cantilever by assembling the upper and lower profiled steel longitudinal beams and the connected profiled steel diagonal braces to meet the needs of structural strength and rigidity

Embodiment Construction
[0060] The present invention is described in detail below in conjunction with the accompanying drawings:
[0061] The purpose of the present invention is to solve the deficiencies that occur when I-beam or Bailey frame is used as the support bracket of the cover beam. The upper and lower section steel longitudinal beams and the section steel diagonal braces connected to them can effectively shorten the length of the bracket cantilever and achieve the purpose of meeting the needs of structural strength and rigidity.
[0062] As shown in the figure: a box-shaped bracket system for a single-column pier group of a bridge. Box bracket pieces are installed on both sides of the bridge pier below the cover beam. The bracket pieces include upper longitudinal beams 101 made of profiled steel, The lower longitudinal beam 102 and the symmetrically arranged diagonal braces 103, wherein the bracket pieces on both sides of the pier are tightened by the round steel tie rods 104 to form an int...

The invention discloses a bridge single column pier assembled box bracket system, which is characterized in that box bracket plates are arranged on two sides of a pier below a capping beam; and each bracket plate comprises an upper longitudinal beam, a lower longitudinal beam and diagonal bracings symmetrically arranged, wherein the upper longitudinal beam, the lower longitudinal beam and the diagonal bracings are manufactured by profile steels; and the bracket plates on the two sides of the pier are pulled and fastened by a round steel pull rod to form an integrated bearing system in order to improve the whole stability of the bracket. The system is stably supported on the pier by a round steel rod, so that the anti-overturning capability of the bearing system is improved in the construction process of the capping beam. The box bracket has the advantages of simple and convenient structural calculation, good stressing condition and safety and stability, little material consumption, high working efficiency, low cost, good economy and the like, and the construction is not limited by terrain.
Description
technical field [0001] The invention relates to the construction of a cover beam on a square single-column pier in a bridge engineering substructure in the field of bridge construction, in particular to a box-shaped bracket for a bridge single-column pier group and an installation method. Background technique [0002] In the current construction of highway and bridge engineering, due to the limitation of bridge height, geological and topographic conditions, the lower part of some bridges adopts the structural form of single-column pier and prestressed cover beam. [0003] Common bridge cover beam construction methods are divided into two types: bracket method (set up steel pipe frame as cover beam support) and bracket method (set support points on pier columns, and use I-beam or Bailey frame as cover beam support). When the height of the bridge pier is large, the bracket method is generally used for the construction of the beam cover due to the less labor and material consum...
