The present invention relates to a formwork elevating platform used in a push-up construction method for producing an entire building by repeatedly pushing up by a height corresponding to the height of a building after the construction of the first floor is completed.

[Conventional technology]

Generally, when constructing a middle-high-rise concrete building, pillars are built up to the top floor, beams and braces are attached, and then formwork assembly on each floor, reinforcement, concrete placement, formwork disassembly, wall member installation, etc. are performed. However, in recent years, several attempts have been made to implement automation in the production of medium- and high-rise concrete buildings. For example, after assembling a large roof such as a gymnasium on the ground and pushing up with a hydraulic jack, or after first constructing the pillars up to the top floor, producing slabs on the ground level and attaching this to the top floor. A method of pulling up sequentially with a winch, further, combining a plurality of prefabricated blocks at the ground level, pushing this up by the floor height with a hydraulic jack etc., and again combining a plurality of prefabricated blocks at the ground level, It is known to push up one by one to produce middle- and high-rise concrete buildings.

In addition, by intensively producing buildings on the first floor at the ground level,
The concept itself of producing the entire building by repeatedly pushing up by the height of the floor after the completion of the building work for the floor is introduced in research papers.

[Problems to be solved by the invention]

Furthermore, in the method of connecting a plurality of prefabricated blocks at the ground level and sequentially pushing up to produce a high-rise concrete building, the prefab itself has columns, structural walls, slabs, etc. from the beginning, so on-site It is difficult to apply this to the production of medium- and high-rise concrete building. In addition, in the idea that the entire building is produced by intensively producing the first floor building at the ground level and repeatedly pushing up,
It is only abstract disclosure, and concrete technical issues such as pillar production, structural wall production, slab production, or push-up method and their solutions are shown, while already completed buildings give spatial constraints. Not not.

The present invention is intended to solve the above problems, and particularly aims to provide a concrete form frame elevating / lowering platform adopted in the push-up method, thereby making manual work as unnecessary as possible and producing a building. The purpose is to improve the sex.

[Means for Solving Problems] For that purpose, the formwork lifting / lowering stand of the present invention has a formwork stand having notches at four corners, and a pushup of the formwork stand arranged on the formwork stand.
