Abstract

PURPOSE:To lift up forms smoothly by allowing the forms to lift up to a next concrete placement block along the wall surface of a prefabricated concrete skeleton with a lifting device installed between forms on both sides. CONSTITUTION:A lift device 4, which lifts up both sided forms 1 and 2, which are installed adjacently to each other, comprises an outer casing 4a and an inner casing 4b, which are connected to the form 1 and a drive motor 4f. Then, the both sided forms 1 and 2 are fixed with the upper end of a prefabricated concrete skeleton 3 with anchor bolts 12 where concrete is cast to the skeleton 3. Then, a stripping device 6 is operated so as to separate the forms 1 and 2 and reaction force receiving posts 5a and 5b from the skeleton 3 while the lifting device 4 is operated so as to lift up the forms 1 and 2 to a next concrete block. It is, therefore, to lift up the forms efficiently.

Further, since the lifting device is equipped with a screw type jack which is operated by a motor instead of a hydraulic cylinder for operating the lifting device, tuning of the jack and operation of minute movement can be easily performed. The mold can be set, demolded and raised smoothly,
Further, there is an effect that the area around the site is prevented from being complicated by hydraulic piping and the apparatus can be simplified.

1. A structure in which right and left molds installed side by side are elevated to the next concrete pouring block along the wall surface of a concrete skeleton that has been constructed by a lifting device installed between the left and right molds. In the self-elevating formwork device described above, the lifting device is an outer casing connected to one of the left and right molds, and an inner casing installed in the outer casing and connected to the other of the left and right molds. When,
A male threaded shaft which is inserted through the inner casing in the vertical direction and is connected to one of the outer casing and the inner casing, and a drive which is connected to an end portion of the male threaded shaft and rotates the male threaded shaft. A screw type jack including a motor and an internally threaded piston rod screwed to the male threaded shaft and connected to the other of the outer casing and the inner casing, and A self-elevating formwork apparatus, wherein one of them is used as a reaction force to slide the outer casing and the inner casing to raise the other formwork.
