Beam-column type support and method for constructing multi-section adjacent bridges using same

Abstract

The invention discloses a beam-column type support and a method for constructing multi-section adjacent bridges using same. Upright posts of the beam-column type support are transversely and vertically connected into a whole in a fixed way and propped against a basic part which transversely runs through the pouring position of each bridge section by a support backout device. When pouring the multi-section adjacent bridges, the support, as a whole, can be moved transversely to the pouring position of each bridge section along the basic part; after the bridge sections in the same transverse rows are poured, the support, as a whole, can be moved to an access road which is on the side of the bridge and extends along the laying direction of the bridge; after being vertically moved to the position corresponding to the next pouring position of the bridge along the access road by a flat wagon, the support is transversely moved to the basic part which is on the bottom of each bridge section of the pouring position of the section, extends transversely and runs through the pouring position of each bridge; by transversely moving the support along the basic part, each bridge section of the pouring position of the section can be poured. In the method, the support can be moved transversely and vertically as a whole without dismounting, thus shortening the pouring construction period of the bridge and improving the construction efficiency.

Description

Technical field: [0001] The invention relates to a beam-column support for supporting bridge molds in the construction of cast-in-place beams and a method for using the support to construct multiple sections of adjacent bridges. Background technique: [0002] When the bridge is poured, it is necessary to use brackets to support the bridge mold, and the beam-column bracket is a form of bracket used more in bridge pouring. The existing beam-column support is mainly disassembled, which consists of a base part, a drop frame device, a column, a beam and a longitudinal beam. The column is supported on the base part by a drop frame device in the form of a sand bucket. Multiple rows of longitudinal beams are installed on the top, and the bridge mold is supported by criss-crossing beams and longitudinal beams to realize the support for bridge pouring. The bracket cannot be moved. After each section of the bridge is poured, the bracket needs to be completely disassembled and transpor...

AI Technical Summary

Problems solved by technology

The bracket cannot be moved. After each section of the bridge is poured, the bracket needs to be completely disassembled and transported to another location where it needs to be poured. After reassembly, another section of the bridge can be poured. However, due to the large volume and weight of its components, it is difficult to disassemble, transport and The assembly is extremely troublesome. The disassembly, transportation and assembly of the bracket requires a lot of equipment, a lot of manpower and working hours, which seriously affects the construction period and efficiency, and the construction cost is also high.

Even for the bifurcated road sections and parallel road sections where the bridges are very close to each other, it is necessary to disassemble and assemble the brackets, resulting in heavy workload, low construction efficiency, long cycle time and high cost
