Problems solved by technology

After the formwork is removed, it needs to be transported twice to increase the construction cost. It is inevitable that the box girder or formwork will be damaged to varying degrees in the process of hoisting with large machinery
The method of dismantling and moving formwork with large construction machinery is greatly affected by objective construction conditions such as construction site conditions and draft depth of construction waters, which affects work efficiency

Abstract

The invention relates to a support cast-in-place box beam side formwork demounting sliding device and an application method thereof. The sliding device comprises sliding rails and a moving trolley in walking fit with the sliding rails. The moving trolley comprises rolling wheels, an axle, a wheel carrier, a bearing face plate, a positioning baffle, a steering rod and a steering shaft. The sliding device has the advantages of being simple in machining technology, low in production cost, wide in application range and the like. The sliding device is applied to construction of a box beam formwork, provides a safety guarantee for project construction, improves the project quality, effectively protects a finished product, achieves the function of conducting in-process control on the project quality and saving cost, and has high use and popularization value.

Description

technical field [0001] The invention relates to the project of cast-in-place box girder with support in the field of engineering construction, in particular to a sliding tool and method for removing the side formwork of the box girder during the construction of cast-in-place box girder with support. Background technique [0002] In the demolition construction of the side formwork of cast-in-place box girder projects for railways, urban roads and highways, the traditional method is to manually remove the formwork. This method has no problem for the removal of general small wooden formwork, but for tall formwork Or the efficiency of manual removal of steel formwork is not high, and the construction risk factor is relatively high. When the formwork is reused, secondary assembly is required, which affects the construction progress and requires a lot of manual screening and assembly of the formwork, which is inefficient, uneconomical and a waste of resources. [0003] Constructi...
