Box girder mobile-type whole-hole cast-in-situ equipment and using method thereof

Abstract

The invention provides box girder mobile-type whole-hole cast-in-situ equipment and a using method thereof. The equipment includes a bailey beam, two rails symmetrically arranged on the bailey beam, side dies slidably assembled on the rails, a pull-up support and a pull-down support. The pull-up support is used for pulling the side dies to slide upwards to set positions, and the pull-down supportis used for pulling the side dies to return to initial positions; the bailey beam is also provided with a bracket, a bottom die arranged on the bracket, and two end dies arranged on the bottom die. The equipment also includes an inner die which comprises support legs fixedly connected with the bottom die and foldable molds connected with the fixed support legs. By adopting a mobile-type integral cast-in-situ process, there is no need to construct temporary facilities, the construction process is simple, and the construction cycle is short. The application ranges of an integral movable formworkand a movable binding mold are increased, and the market is expanded for the steel structure machining and manufacturing industry. The use of some large-scale equipment can be avoided, and the construction risk is relatively lowered.

Description

Technical field [0001] The invention relates to the field of construction technology, in particular to a box girder movable whole-hole cast-in-situ equipment and a use method thereof. Background technique [0002] In the bridge construction, the porous cast-in-place simply supported box girder usually adopts the mobile formwork or the segmental assembly process. If a multi-span long simply supported beam is constructed with a mobile formwork, the equipment investment is relatively large, the equipment installation and dismantling is slow, and the speed of the moving formwork is slow; if the segmental assembly process is adopted, another segmental prefabrication yard is required. Need to be equipped with large tonnage segment assembly bridge building machine. In summary, both processes need to be equipped with large-scale professional equipment, which is difficult to operate, expensive in large projects, and complex construction techniques, which cannot meet the construction peri...

AI Technical Summary

Problems solved by technology

To sum up, both processes need to be equipped with large-scale professional equipment, the operation of the equipment is difficult, the cost of large-scale construction is high, and the construction process is complicated, which cannot meet the construction period requirements of the Yinxi project
