Assembled hoop support suitable for special pier and method for constructing capping beam by using same

Abstract

The invention discloses an assembled hoop support suitable for a special pier and a method for constructing a capping beam by using same. The assembled hoop support suitable for the special pier comprises a plurality of hoops; the plurality of hoops sleeve a bridge pier in a spaced manner; patching adjusting plates with adjustable lengths are contained in the hoops; adjusting plates are correspondingly mounted / not mounted at four internal corners in the hoops to adjust shapes and sizes of the internal spaces of the hoops and adjust the lengths of the patching adjusting plates in a matched manner to adapt to bridge piers with various special shapes; and therefore, the hoops stick to the bridge piers; the two adjacent hoops are connected with each other through connecting plates; and the number of the hoops is adjusted to adapt to the bridge piers with different heights. The assembled hoop support suitable for the special pier can adapt to the construction of the capping beams of the bridge piers with the various special shapes; and a lot of full supports are not needed in the capping beam construction process.

Description

technical field [0001] The invention relates to the field of assembled hoop brackets suitable for special-shaped piers. More specifically, the present invention relates to a prefabricated hoop support suitable for special-shaped piers and a construction method using the cap beam thereof. Background technique [0002] Bridges are an important part of my country's transportation construction. As the substructure of the bridge, the cap beam supports, distributes and transmits the upper load of the bridge. However, for bridges with high piers, if the support structure is used for construction, the amount of support structure will be too large, and the stability of the support structure will not be guaranteed. In addition, in some areas, the geological conditions are extremely poor, and the bearing capacity of the foundation is low, so there is no condition for scaffolding construction at all; [0003] Due to the particularity of the structure of the high pier cap beam itself a...

Problems solved by technology

[0003] Due to the particularity of the structure of the high pier cap beam itself and the geological conditions in some areas, the construction of the cap beam may have problems such as low construction efficiency, cumbersome construction process and high construction cost, but there is no new set of methods to solve it. Therefore, it is urgent to design an assembled hoop bracket structure suitable for special-shaped piers to solve this problem, which can avoid the erection of full-wall brackets during the construction of high-pier cap beams and ignore the influence of foundation bearing capacity, and does not require Opening holes on the pier column affects the structural quality of the pier body, and at the same time can adapt to various special-shaped piers
