Problems solved by technology

[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 strength development of concrete

Embodiment Construction

[0016] see Figure 1 to Figure 10 , 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 end of the pair of movable formwork 12, and pla...

Abstract

The invention discloses a rollover template capable of lifting and rolling over, which is mainly used for cast-in-place barrel body structure construction of the building engineering field, and is quick and convenient in construction. The rollover template mainly comprises a beam, reinforcing plates, channel steel, movable templates and U-shaped pliers. The working principle of the roller templateis as follows: mounting reinforcing steel bars and pouring concrete in a cavity formed by a pair of movable templates, loosening buckles at the lower ends of one pair of movable templates after concrete is finally condensed, lifting the U-shaped pliers to upwards turn over the movable templates, enabling the movable templates to de-mould from cast concrete, putting one pair of pin rolls at the upper ends of one pair of movable templates into a third row of U-shaped slots of a flange after upwards turning over one pair of the movable templates by 180 degrees, pressing the third row of bucklesagain, locking one pair of pin rolls at the upper ends of one pair of the movable templates, pouring concrete in the cavity formed by one pair of the movable templates, continuously upwards turning over the templates and pouring concrete with the same method after the concrete is finally condensed until concrete pouring work of next construction stage is accomplished.

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 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 can lift and turn over the formwork with a spreader, saving labor. It consists of ...
