Embodiment Construction

[0013] see Figure 1 to Figure 7 , when the climbing formwork device stays at a certain height of the cylinder wall 11, the temporary fixing parts withstand the lower ends of the pair of bottom beams 5, first install a pair of movable formwork 12 on the bottom row of the turning formwork, and one The upper and lower pin shafts 9 of the movable formwork 12 are all put into the U-shaped groove 6 of the flange 1 of the adjacent channel steel 3, and the upper and lower part buckles 7 are fastened together, and the O-shaped waterstop strip A13 of a pair of movable formwork 12 is Close to the cylinder wall 11 that has been poured and has reached a certain strength, and then install steel bars and pour concrete in the cavity formed by a pair of movable formwork 12, and the O-shaped waterstop strip A13 of the pair of movable formwork 12 prevents concrete from leaking After the concrete is finally set, loosen the fasteners 7 at the lower ends of the pair of movable formworks 12, and tu...

Abstract

The invention discloses a rollover formwork for a climbing formwork device, and is mainly used for structural construction of cast-in-place cylinders in the field of constructional engineering. By means of the rollover formwork, convenience is brought to construction. The rollover formwork is composed of a transverse beam 10, stiffening plates 2, U-steel 3, movable formworks 12 and bottom beams. According to the working principle, steel reinforcement bars are installed in a cavity formed by the movable formworks, and concrete is poured into the cavity formed by the movable formworks; after final setting of the concrete, fasteners at the lower ends of the two movable formworks are loosened, the two movable formworks are overturned upwards, at this moment, the movable formworks are separatedfrom the poured concrete, after the two movable formworks are overturned upwards 180 degrees, two pins shafts at the upper ends of the two movable formworks are put into U-shaped grooves in the thirdrow in flanges, fasteners in the third row are pressed down, the two pin shafts at the upper ends of the two movable formworks are locked up, concrete is poured into the cavity formed by the movableformworks, after final setting of the concrete, and in the same way, the formworks continue to be overturned upwards, and the concrete is poured until the concrete pouring work during a construction period is completed.

Description

technical field [0001] The invention is mainly used for the construction of cast-in-place cylinder structures in the field of construction engineering. Background technique [0002] At present, climbing formwork devices are used in the construction of cast-in-place cylindrical structures in the field of construction engineering, and the formwork is made of sliding film formwork. This formwork has high requirements for the lifting capacity of the lifting equipment, and when the formwork slides up, it exerts a relatively large force on the poured concrete. Large tensile stress will affect the later stage strength development of concrete. Contents of the invention [0003] The invention solves the above-mentioned problems. It does not have high requirements on the lifting capacity of the lifting equipment, and at the same time, it does not affect the later strength development of the poured concrete. It consists of beam (10), stiffening plate (2), channel steel (3), movable ...
