Supporting device specially used for flyover box culvert pouring

Abstract

The invention discloses a supporting device specially used for flyover box culvert pouring. The device comprises a first pouring assembly having a pair of fixed pouring units arranged at intervals; asecond pouring assembly provided with a pair of movable pouring units which are arranged at intervals; a lifting mechanism provided with a transmission structure and a connecting assembly in transmission connection with the transmission structure; and a supporting structure provided with an outer supporting assembly arranged on the outer side of each side wall pouring cavity and an inner supporting assembly arranged between the two side wall pouring cavities. The assembly is simple and convenient, the length of each outer supporting unit can be adjusted, only the lower portions of the outer supporting units need to be fixed to the fixing plate after adjustment is completed, and installation is simple and convenient; the inner supporting assembly can support the two inner side plates by adopting the transverse supporting unit with a telescopic function, the inner supporting units can be disassembled only by disassembling the transverse supporting unit during disassembling, and thus disassembling and assembling are easy and convenient.

Description

technical field [0001] The invention relates to the field of box culvert construction, in particular to a special support device for overpass box culvert pouring. Background technique [0002] The box culvert construction generally adopts the cast-in-place method, that is, the bottom layer is set in the excavated trench, a layer of concrete cushion is poured, and the processed steel bars are bound on site, the inner and outer molds are supported, and then the concrete is poured. . When pouring concrete, for larger box culverts, the bottom half of the bottom plate and side walls are usually poured first. After the concrete reaches a certain strength, the steel bars of the remaining height are bound, and the upper inner and outer molds are supported again, and finally the side of the box culvert is poured. The upper part of the wall completes the construction work of the box culvert. [0003] In the process of box culvert construction, the supporting device of the box culver...

AI Technical Summary

Problems solved by technology

The connection nodes between the lower inner mold and the upper inner mold of the existing box culvert support device, the connection nodes between the upper outer mold and the lower outer mold, and the connection nodes between the support system and the inner and outer molds have a large amount of assembly work, which seriously affects the construction progress; at the same time The support system structure of the existing box culvert support device is complex and cumbersome to disassemble, which not only affects the construction progress to a certain extent, but also has poor stabilizing effect
