The whole continuous retreat method of the mobile formwork beam surface

Abstract

The invention relates to an integrally continuous backing method for a moving formwork on a girder face. The integrally continuous backing method comprises the following steps that (A), a rail and jack supporting positions are arranged on the girder face, and a first backing girder is lifted and downwards placed on jacks; (B), a second backing girder is arranged, and a connector of the second backing girder is aligned with the first backing girder; (C), horizontally moving suspension girders and a horizontally moving jack system are arranged; (D), a main girder is connected with a backing upper suspension girder; (E), the backing upper suspension girder and anchor holes of the horizontally moving suspension girders are fixed on preformed holes of a frange plate by suspension rods; (F), according to the mounting steps, a back horizontal girder is connected with the main girder; (G), opposite-pulling finish-rolled deformed steel bars for brackets are removed, and the brackets are horizontally moved out of holes; (H), the formwork is integrally and horizontally moved to a designated position, and a vertical stabilizer rod is arranged; and (I), all suspension rods of the preformed holes of the frange plate are relieved, the backing upper suspension girder and a vertical pushing device on a rail of the back horizontal girder are synchronously operated, and the moving formwork is subjected to continuous backing travel till backing construction is finished. According to the integrally continuous backing method, the backing construction period of the moving mould frame is shortened, the input of mechanical equipment is reduced, construction cost is saved, and the construction safety risk is lowered.

Description

technical field [0001] The invention relates to a construction technology for retreating a mobile formwork, in particular to a method for integrally and continuously retreating the beam surface of a mobile formwork. Background technique [0002] At present, most of the self-propelled mobile formwork back technology adopts the traditional method of using its own corbels to retreat hole by hole. In this traditional process, it is necessary to repeatedly transport the corbels and consolidate the corbels at high altitudes during the construction process. The process changes frequently and the construction period is short. Longer, high-altitude construction safety risks are large disadvantages. Contents of the invention [0003] The purpose of the present invention is to provide a method for the entire continuous retreat of the mobile formwork beam surface, which mainly solves the technical problems existing in the above-mentioned prior art. It shortens the construction period ...
