Fabricated steel-concrete composite structure culvert

Abstract

The invention relates to the technical field of structural culverts, in particular to a fabricated steel-concrete composite structure culvert which comprises a bottom plate body, a standing plate body and a top plate body, first inserting blocks are fixedly connected to the upper surface of the bottom plate body, the four sets of first inserting blocks are symmetrically distributed in pairs, and first locking holes are formed in the side walls of the first inserting blocks. A second inserting block is fixedly connected to the bottom of the top plate body, a second locking hole is formed in the side wall of the second inserting block, positioning grooves are formed in the top and the bottom of the standing plate body, fixing mechanisms corresponding to the first inserting block and the second inserting block are arranged on the side wall of the standing plate body, and a positioning hole is formed in one side of the upper surface of the bottom plate body; a locking mechanism is arranged on the other side of the upper surface of the bottom plate main body, when the bottom plate main body, the standing plate main body and the top plate main body are mounted, positioning and mounting of the bottom plate main body, the standing plate main body and the top plate main body are facilitated, the splicing time is saved, the accuracy of the mounting position is guaranteed, and the bottom plate main body, the standing plate main body and the top plate main body can be temporarily fixed.

Description

technical field [0001] The invention relates to the technical field of structural culverts, in particular to an assembled steel-concrete composite structure culvert. Background technique [0002] The traditional culvert engineering construction method is mostly on-site vertical formwork pouring, which has many disadvantages, such as scattered construction points, difficult control of construction quality, long cycle of turnover of formwork and support materials, construction progress is greatly affected by winter and rainy seasons, and construction period is long. The problem is usually solved by the method of prefabricated steel concrete composite structure. [0003] In the existing prefabricated steel-concrete composite structure culverts, the bottom plate is generally installed first, then the side plates are installed, and finally the top plate is installed on the top of the two side plates. The bottom plate, side plates and top plate are fixed by concrete. The culvert ...

Problems solved by technology

[0002] The traditional culvert engineering construction method is mostly on-site vertical formwork pouring, which has many disadvantages, such as scattered construction points, difficult control of construction quality, long cycle of turnover of formwork and support materials, construction progress is greatly affected by winter and rainy seasons, and construction period is long. The problem is usually solved by the method of prefabricated steel concrete composite structure

[0003] In the existing prefabricated steel-concrete composite structure culverts, the bottom plate is generally installed first, then the side plates are installed, and finally the top plate is installed on the top of the two side plates. The bottom plate, side plates and top plate are fixed by concrete. The culvert of the concrete composite structure is not equipped with a corresponding positioning mechanism, which leads to a slow installation process of the bottom plate, side plate and roof plate during installation, because it is necessary to ensure that the bottom plate, side plate and roof plate fit together during installation , Moreover, there is no temporary fixation, which makes the installation position not accurate enough, and also prolongs the construction period, and the stability of the culvert in the later period is not guaranteed
