Description

The invention relates to the construction and can be used in the construction of walls of monolithic reinforced concrete.

Known formwork for walling, including jacking ram with jacks and formwork shields, hingedly connected with the help of screw devices with jacking frames (1).

The disadvantage of this formwork is the high labor intensity of the formwork work.

The closest technical solution to the invention is a form-climbing formwork, including jacking frames with jacks, jacking rods and formwork shields [2].

The disadvantages of this formwork are high labor costs for formwork work in the formation of the corners of the walls, since the construction, formwork does not provide for the use of special corner elements

The purpose of the invention is to reduce the complexity of formwork work.

This goal is achieved by the fact that the lifting-adjustable formwork, including jacking frames with jacks and jacking rod2

them and formwork boards, equipped with corner elements, support shoes, consoles, brackets, studs and springs, with the corner elements located between adjacent boards, on the ends of which the studs are fixed and hingedly connected to jackframes, and the support shoes

Ιθ by means of springs and brackets installed on consoles, which are rigidly fixed to the shuttering boards.

At the same time, corner elements and support shoes are made with angled to the longitudinal axis

15 through slots in which the studs and brackets are respectively placed

four

On the frame 1, the pins U are fixed, which are located in the horizontal grooves 10, the bars 11, each of which is fixedly attached to the groove of the inner corner element b and to the outer edge of the outer corner element. The vertical edges of the outer stitching 4 and the inner shield 5 are fixedly attached with threaded pins 12, which are located in the oblique grooves 13 of the shelves 1 of the corner elements b and fixed with the help of nuts 14 so that they can be moved. To the structural elements 15 of the rigidity of the shields 4 and 5 are fixedly attached to the console 1B, in 1 of which with the possibility of axial movement of the fixed support bracket 17, passing through the oblique grooves 18 of the hollow each support Shoe.

Each shoe has holes 19 in the side walls, and inside the support beam 20, through which the spring 21 passes, constantly pressing the shoe to the wall 22 being built.

The formwork works as follows 2 times.

After the concrete of the next tier of concreting pick up the stripping strength, release the nuts 14, the impulse of lifting to the jacks 2 is given, and the jacking frames 1 begin to rise. When this lifting force through the pins 9 and the strap 1 is transmitted to the corner element b, which, rising and trying to bring the pins 12 through the grooves 13 closer to the top corner of the corner element 6, opens the shields from concrete and moves them along the axis of the support bracket 17.

The formwork unit, having adopted the minimum size, rises upwards to the next tier of concreting, while the support bracket 17, sliding along the groove 18 and relieving pressure from the internal and external support shoes, carries them upward with a slide of 4

the wall 22 due to the spring pressure 21 through the beam 20. When the formwork reaches the next mark, an impulse is given to the jacks to stop and '' step in place ¹¹ . Jacking frames 1, and with it the whole structure hanging on it, begins to fall. In this case, the support shoes 7 and 8 are in place and in the process of lowering the support bracket 17 and sliding along the groove 18, they are increasingly pressed against the concrete and the shields 4 and 5 hang on the uprights in the consoles 16. Corner elements b, continuing to move down the slots 13 move the pins 12 to the upper position, i.e. move the formwork unit to the design position for concreting.

The usefulness of the invention lies in the efficiency of the release of formwork from concrete, exhibition formwork in the design position and increase the turnover of formwork.

Claims (2)

Claim 1. Lifting-adjustable formwork, including jacking frames with jacks and jacking rods and formwork boards, which are designed so that, in order to reduce the labor intensity of formwork, the formwork is equipped with corner elements, support shoes, and consoles brackets, studs and springs, the corner elements are located between adjacent shields, on the ends of which the studs are fixed and hinged to jacking frames, and the support shoes are mounted on brackets by means of springs and brackets deck shields. 2. Formwork on π. 1, the fact that the corner elements and support shoes are made with angled grooves at an angle to the longitudinal axis, in which the studs and brackets are respectively located.
