Abstract

The invention relates to construction and can be used in formwork for the continuous erection of monolithic structures with insulated walls. The purpose of the invention is to reduce labor costs during the regular erection of monolithic walls with voids for insulation. The volume-mobile formwork contains frame 1 with vertical telescopic pillars 2 and working deck 3, horizontal pivoting beams 4 with internal 5 and external 6 shields suspended on them, provided with i (L U i a

The invention relates to a structure and can be used in formwork for the continuous erection of monolithic structures with insulated walls.

The purpose of the invention is to reduce labor costs in the construction of monolithic walls with voids for insulation,

5. .,. The volume-mobile formwork contains frame 1, on which vertical telescopic stands 2 are mounted. On the uprights 2, the working floor 3 is fixed on the axial bottom surface, on which beams 4 with internal 5 and outer formwork boards 6 mounted on them are mounted. At the upper ends of these shields, brackets are made with sockets 7 open from above. A truncated pyramid-shaped box 9 in the form of a hollow open bottom, in the lower part of which there is an inflatable chamber 10, covering the box below and the gaps between the box and the upper edge of the previous floor of the erected structure, and the upper, larger base of this box is rigidly fixed on bar 8. At the same time, bar 8 has on its cores rotary eccentric cams 11

inserted into the slots 7 and connected by a rod 12. A handle 13 is provided for rotating the rod 12 with the cams 11.

Along the formwork panels 5 and 6 along the beams 4, the duct 14 is laid, having branches 15 to the chambers 10.

To increase the sealing and centering of the chamber 10 inside the hollow box 9, centering rollers 16 can be made in the form of triangular prisms in contact with the inflatable chamber 10.

The formwork works as follows.

Before concreting the next tier, in which there should be emptiness for insulation, shields 5 and 6 are pulled together and between the shields with the help of the strip 8 they hang hollow-forming elements, which are fixed by turning the cams 11 in the slots 7 in a horizontal position. The beams lay the air duct 14, which is connected to the camera 10.

Then the chambers 10 are filled with air, which cover the gaps between the lower edge of the emptying core and the upper edge of the previous floor of the wall being erected. These gaps arise due to differences in size between the lower and upper bases of the box 9.

After concreting the Russ before turning out the shields 5 and 6, using the knobs 13, rotate the eccentric cams 11 by 90 °, placing them in a vertical position, resulting in a gap in each slot 7, allowing the shields 5 and 6 to deviate from the vertical

position for stripping. At the same time, air from the chambers 10 is released and the shields, together with the core-forming machine, are telescoped by pillars 2, are raised to the next Russian, where, after the SHITES 5 and 6 are tightened, the cams I1 are rotated in slots 7 by 90 ° to the horizontal position and the operations are repeated,.

In order to form voids in the lowermost shaft, chamber 10 is removed from the void former.
