Special support device for overpass box culvert pouring

Abstract

The invention discloses a special support device for pouring a box culvert of an overpass, comprising a first pouring component, which has a pair of fixed pouring units arranged at intervals; a second pouring component, which has a pair of movable pouring units arranged at intervals; and a lifting mechanism, which has a transmission a structure and a connecting assembly drivingly connected to the transmission structure; and a support structure having an outer support assembly disposed outside each sidewall casting chamber and an inner support assembly disposed between the two sidewall casting chambers. The invention is simple and convenient to assemble, the length of each outer support unit can be adjusted, and after the adjustment is completed, only the lower part of the outer support unit needs to be fixed on the fixing plate, and the installation is simple and convenient; the inner support component adopts a horizontal support with a telescopic function The unit can realize the support of the two inner side panels, and the inner support unit can be removed by removing the lateral support unit, and the disassembly and assembly are simple and convenient.

Description

technical field [0001] The invention relates to the field of box culvert construction, in particular to a special support device for pouring box culverts of an overpass. Background technique [0002] The construction of box culverts 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 then the processed steel bars are bound on site, the inner and outer forms are supported, and then concrete is poured. . When pouring concrete, the larger box culverts are generally first poured on the bottom half of the bottom plate and the side walls. After the concrete reaches a certain strength, the steel bars of the remaining height are bound, the upper inner and outer forms are supported again, and finally the side of the box culvert is poured. On the upper part of the wall, the construction of the box culvert is completed. [0003] In the process of box culvert construction, the support device of...

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
