Prefabricated assembly type cover beam and construction method thereof

Abstract

The invention discloses a prefabricated assembly type cover beam and a construction method thereof. The prefabricated assembly type cover beam comprises a plurality of cover beam sections and threadedsteel rib connectors, wherein a plurality of threaded steel ribs are pre-buried in each cover beam section, the cover beam sections are spliced and assembled, and an operation slot hole is formed inthe spliced part, corresponding to the threaded steel rib, between each two adjacent cover beam sections; and the threaded steel ribs of each two adjacent cover beam sections are spliced through one threaded steel rib connectors, and the threaded steel rib connector is accommodated in each operation slot hole. Compared with an existing cover beam formed by connecting three sections of structures through pre-stressed steel ribs and slip casting into a whole, the prefabricated assembly type cover beam has the advantages that the threaded steel ribs and the threaded steel rib connectors are standard products and do not need to be customized and machined by virtue of special equipment, so that the construction is simplified, and the construction cost is lowered; and by utilizing a mechanical connection manner, the subsequent construction can be carried out on the cover beam without waiting, so that the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a prefabricated and assembled cover beam. The invention also relates to a construction method of a prefabricated assembled cover beam. Background technique [0002] The prefabricated bridge system mainly includes prefabricated assembled girders and prefabricated assembled bridge piers. The assembly of prefabricated and assembled main girders is usually carried out late at night. Except for the temporary occupation of some lanes for assembly construction at night, the number of ground lanes remains basically unchanged during the construction period. It not only reduces the impact on the atmospheric environment and road traffic, but also reduces the disturbance to citizens' lives. The cover beam adopts prefabricated assembly construction, without the need to erect supports, which can greatly speed up the construction progress and effectively reduce the interference to...

AI Technical Summary

Problems solved by technology

But this cover beam construction method uses prestressed steel bars and grouting to connect the three sections of the structure into a whole. It requires special prestressed tensioning equipment and grouting equipment, and the cost is relatively high. 7 days) before the follow-up construction can be carried out on the cover beam, and the construction period is longer

[0004] To sum up, how to solve the problem of high construction cost and long construction period of the cap beam has become an urgent problem to be solved by those skilled in the art
