Abstract

The invention relates to the construction, in particular to installation, and can be used in the construction of buildings with a mine by the method of raising floors. The aim of the invention is to reduce the consumption of materials for mounting equipment and increase productivity. To do this, during the construction of the carrier shaft 6 by 2/3 of its height, a package of scans of the upper floors is simultaneously made on the overlap of the first formed structure of the 12th floor, which is connected by flexible rods 15 to the tip 10 of the shaft 6. The upper slab 13 of the scan package is connected to foundation 1 by means of flexible tubes of r 16 placed in 6 channels previously made in the head 10 and the body of the shaft. During the forward run of the jacks 3, the mine 6 is further erected with the simultaneous deployment of the upper developments of the building floors and the extension of the formed structures of the lower floors, and during the reverse course of the jacks 3 - the deployment of the lower floors develops due to the capture of 3 flexible tons of jacks with jacks 16. 14 il.

Description

FIG. 6

The invention relates to the construction, in particular to installation, and can be used in the construction of buildings with a load-bearing shaft or shaft and suspended floors using the lifting method.

The aim of the invention is to reduce the consumption of materials for mounting equipment and increase productivity.

Figures 1-14 depict the sequence of the method for erecting a multi-storey building.

The method is carried out as follows.

I First, the foundations 1 are concreted (buildings in the basement of which are arranged cells 2 for houses. Crates 3. Jacks 3 are installed in cells 2 so that their movable hydraulic cylinders slide through holes in pallet 4 of formwork 5 to make mine 6. Formwork 5 contains a core 1 with formwork mechanisms and internal formwork shields 8. ttta foundation form formwork 9 for making lower spatial monolithic structures of floors. In this way, heading 10 is rigidly connected to a fragment of mine 6. strength boron with concrete of the shaft, its tip 10 together with the fragment is pulled out of the formwork 5 into which concrete mix 11 is loaded, and until the end of its hardening, the jacks 3 are removed to the lower position, re-fuse the previously raised shaft 6 onto the concrete mix, compacted with its weight the top 10 with a fragment of mine 6. Next, the formed next fragment is pulled out of the open formwork, repeating the operation until the mine is raised to 2/3 of its height. Simultaneously with the erection or ascent of the shaft 6, formwork 9 concretes a three-dimensional spatial structure of the 12th floor, on the floor of which concretions of upper floors concrete consisting of 13 floor slabs and partition walls 13, which are connected with flexible anchors with overlapping floor slabs. Simultaneously with the concreting of the reamers, the hole-former, engineering equipment and embedded parts are laid in the structure. In the process of raising mine 6, its position is stabilized by

tension flexible t g passed through the channels formed in the body of the mine channel-forming. Upon completion of the construction of the mine 6 by 2/3 of its height (FIG. 4), the structure of the 12th floor is connected to the head 10 of the mine 6 by flexible rods 15 of unchangeable length. The upper slab 13 of the overlap of the floor sweeps is connected to the base slab by flexible rods 16, which are slidably slid through the channels previously made in the tip 10 and in the body of the shaft 6. In the process of lifting the mine, 6 tons and 16 tons are vented from the drum devices installed on the foundation. Then, the flexible rods 16 are fastened to the foundation with clamps (not shown).

In the process of raising the shaft 6, the sweep 17 of the upper floor is unfolded and the structure 12 of the volumetric floor is extended from the formwork. T-gi 16 at this time work on the principle of the reverse polyspast. At the end of the construction of the shaft 6, the concrete mix is loaded into the formwork 5 and until the end of its hardening the jacks 3 are removed to the lower position, having previously secured the flexible rods 16 by means of functional devices (not shown) hooked onto the jacks, i.e. The jacks 3 at the same time seize the gigi 16. With the return stroke of the jacks 3 to the design position, install a scan 18 of the next floor, second from the top (FIG. 8), while simultaneously retracting the advanced building onto the concrete mix loaded into the formwork 5. Thus, in one working stroke of the jacks in the upper part of the building, two floors are installed in the design position and one is grown from below. The excess t g is wound on drums.

The operations are repeated cyclically until all sweeps are installed in the design position while simultaneously building up the building for the remaining 1/3 of the height.

Having completed the building erection to the project height, flexible rods 16 are subjected to prestressing, the channels are filled with concrete on a small aggregate, the excess drags are cut off, the formwork and lifting equipment are dismantled, the pallet 4 and the channel formers are left in

the body of the mine, the cells 2 are filled with concrete.

If necessary, the carrier shaft 6 is erected in a manner of growing from prefabricated elements. Slabs can be suspended in groups to intermediate floors.

Such an embodiment of the method makes it possible to reduce the consumption of materials for the assembly equipment and to increase the productivity.
