Light-type turnover synchronous jacking and pulling support and using method

Abstract

The invention discloses a light-type turnover synchronous jacking and pulling support. The light-type turnover synchronous jacking and pulling support comprises at least two supporting frames, a supporting base and formwork jacking connecting devices; the supporting base comprises a combined connecting bearing and a jacking positioning plate located under the combined connecting bearing; the middles of the at least two supporting frames are all arranged on the combined connecting bearing in a penetrating manner, and the at least two supporting frames can rotate relative to the combined connecting bearing; and the formwork jacking connecting devices are used for being connected with connecting parts of a movable formwork frame and can rotate relative to the connecting parts of the movable formwork frame, the formwork jacking connecting devices are installed at the ends of the free ends of the supporting frames, and the jacking positioning plate is used for being arranged over a jack. According to the light-type turnover synchronous jacking and pulling support, the effect that a side formwork synchronously jacks a formwork in construction of corridor type engineering projects such asutility tunnels is achieved, and then the formwork construction operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pipe gallery construction, in particular to a light-duty turnaround synchronous jacking and pulling support and a method for using the same. Background technique [0002] At present, in the construction of corridor engineering projects such as comprehensive pipe corridors, the mobile formwork system is one of the most important construction methods. Its high efficiency and safety characteristics ensure the smooth implementation of on-site construction. However, in the process of supporting the formwork on the side formwork of the mobile formwork, the formwork on the left and right sides needs to be supported separately, which requires a large amount of construction work and is time-consuming and labor-intensive; in the process of supporting the formwork on one side, the hydraulic jack equipment used is difficult to fix. It is very difficult and the construction efficiency is low; at the same time, when th...

Problems solved by technology

However, in the process of supporting the formwork on the side formwork of the mobile formwork, the formwork on the left and right sides needs to be supported separately, which requires a large amount of construction work and is time-consuming and labor-intensive; in the process of supporting the formwork on one side, the hydraulic jack equipment used is difficult to fix. It is very difficult and the construction efficiency is low; at the same time, when the single-sided formwork is opened separately, the overall stability of the mobile formwork cannot be guaranteed, and tilting or deformation is very likely to occur. It is difficult to control the accuracy of the formwork, and there is a great potential safety hazard

The above-mentioned problems caused by the construction of single-sided formwork supporting formwork have seriously restricted the operating efficiency of the mobile formwork system, brought greater safety hazards, and increased the construction cost of the project, which urgently needs to be optimized
