Abstract

The invention provides a cast-in-situ capping beam supporting formwork system and a construction method. The outer side of a pier column is provided with an upper hold hoop and a lower hold hoop, andfurther provided with a water-retaining rain cloth; a first formwork and a second formwork are hoisted together to a set height, the second formwork is pulled in a slidable mode to a set transverse position through a sliding pull cable, and the spatial position of the second formwork is controlled through a bottom adjusting body and an adjustable stay rod; pouring benches are placed on the first formwork and the second formwork, and capping beam concrete pouring construction is performed; demolding construction is synchronously carried out through a demolding pull rod and a demolding pressurizing pipe, and damage to the second formwork caused by demolding construction is reduced through an elastic support body; steam curing is carried out on the capping beam concrete first, then sliding water-spraying curing construction is carried out, so that installation and construction efficiency of the on-site construction structure is improved, the difficulty of capping beam formwork installation and construction is reduced, and the quality of capping beam concrete pouring and maintenance construction are improved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a cast-in-place cap beam formwork support system and construction method that can improve the installation and construction efficiency of on-site construction structures, reduce the difficulty of installation and construction of cap beam formwork, and improve the quality of cap beam concrete pouring and maintenance construction. Cast-in-place cap beam construction works. Background technique [0002] In recent years, with the continuous improvement of people's living standards, the requirements for transportation are getting higher and higher, and the demand for bridge construction is also increasing, and the bridge span is getting larger and larger. The cast-in-place cap beam is a common engineering structure in bridge engineering, and its formwork support quality and maintenance are often the focus of construction engineering control. [0003] In the prior art, there is a T-s...
