Description

AND

The invention relates to the construction and may find application in the construction of monolithic buildings.

The purpose of the invention is to expand technological capabilities and reduce labor costs.

The drawing shows the formwork, vertical section.

The formwork includes a deck of formwork overlap 1, rigidly mounted on the upper end of the inner frame 2 and provided with guides 3 that are cantileverly placed along the perimeter and on which the outer formwork 5. communicating with a tear-off attachment b made in the form of a screw jack are suspended by means of a roller support 4 located on the guide rail 3, and the internal

formwork boards 7 are movably mounted on the outer frame 8 On the guide 9 of the inner frame 2, made with slats, the ratchet grip 10 is movably mounted that is pivotally connected by a hydraulic cylinder 11 with the outer frame 8, on the racks 12 of which the locking paws 13 are installed, preventing the frame from lowering at the moment of interception ratchet grip 10 when stepping the frame one relative to another.

In order to rest on the walls of the erected structure, the inner and outer frames are provided with lugs 14. To prevent the shuttering boards from spreading, studs 15 are provided, tightening the inner and outer shields between them.

When concreting floors, the gap between the deck and the walls being erected overlaps with the sliding plates 16.

The formwork works as follows.

The formwork is installed on the base of the erected structure, the shields are pinched with studs and concreting is performed at the lowest position of formwork shields 5 and 7. After the concrete has been stripped of concrete, the studs 15 are removed, the shields are removed from the walls, the hydraulic cylinder 11 is turned on and the formwork is lifted, the subsequent floor, shields are studded with studs 15 and proceed to subsequent concreting.

After the completion of concreting the floor, lugs 14 of the inner frame 2 are removed from the walls, the inner frame 2 is raised to the height of the boards, then the outer frame 8 is raised with the formwork boards, and the cycle is repeated.

After the walls have been erected to the entire height of the building, the external formwork boards 5 and the guides 3 are removed and the floors are concreted by alternately lowering the inside 2 and outer 8 formwork frames down to the first floor. At the same time, the internal shuttering boards 7 are retracted from the walls, and the gap between the deck and walls during concreting is blocked by plates 16. Niches formed during the construction of walls for abutment of the stops 14 are used to install the floor reinforcement and are laid during the concrete pouring of the floors. Formwork dismantling is carried out on the first floor.

Claims (1)

Invention Formula Movable formwork for erecting walls and floors, containing outer and inner boards of wall forms, deck formwork, supporting frame, supporting devices and lifting mechanism, characterized in that, in order to expand technological capabilities and reduce labor costs, the formwork is equipped with detachable formwork panels walls made in the form of jack, and the supporting frame is made of two frames - inner and outer, while the deck of the formwork is rigidly fixed on the upper end of the inner frame and is equipped with a cantilever guides, on which the outer formwork panels that interact with the detachable device located on the guideway are suspended by means of the rotor support, and the inner formwork panels are movably mounted on the outer frame of the frame.
