Known sliding formwork for the construction of mine battered rock-reinforced reinforced concrete, including flat steel supporting structures — rounding, shields, U-shaped frames with lifting mechanisms, support rods 1.

The disadvantage of the sliding formwork is that the lifting of the roof elements is carried out during the construction of the walls of the shaft enclosing shaft and after dismantling the formwork, and the roof is installed at a considerable height (more than 100 m). At the same time, considerable material and labor resources are spent on manufacturing, assembly and demolition of the formwork, as well as fabrication and installation of the roof of the object, which leads to higher construction costs and to an increase in its time. In addition, due to the small spatial rigidity of the supporting flat structures, it is necessary to install a large number of U-shaped pipes with lifting mechanisms of small installation pitch (not more than 2 m), which makes it difficult for the concrete walls to be reinforced with ready-made reinforcement cages and ipeovi / T Hand-held visor fittings at the construction site. ia presence of a sick number of lifting mecanisms requires the greater the cost of their manufacture, assembly, and exploration, makes it difficult to ensure their proper pa6oTiii, which leads to non-recutting and torsion formwork and all this can lead to a reduction in the quality of concrete; ove x osti.

1) 11 erecting an object in a sliding structure does not require up to 1%; it is necessary to lift and mount the roof mounting elements at a height, however, and the design of the circle is made flat with non-volume rigidity and require the installation of a large number of U-shaped frames with a small tag of their installation to ensure the stability of the shape of the walls, which makes it difficult to 1 use ready-made frame carcass i; It requires the manufacture of hand-held equipment and the concreting of the walls of the building.

which reduces tempy concreting walls. In addition, the formwork design does not ensure the stability of its movement without distortions and torsions and thus reduces the quality of concrete work.

The aim of the invention is to reduce material and labor costs in the construction of the object and improve the quality of concrete work.

The goal is achieved by the fact that

FIG. 7

Sliding onalubka for erecting tower towers from monolithic.; 1 reinforced concrete 1 consists of unique metal structures — circling 2, which are simultaneously with parts of the volume blocks of roofing and 3 of the object being erected and the inventory of connecting volumes of general elements 4-7 interconnected by bolts and dismantled after the erection of the object. Supporting metal structures-circles 2, made of volume blocks of the roof 3, consist of trusses 8 and links 9 forming the roof 3. For the period of erection of the object walls to the supporting structures m-circles 2 and inventory connecting volume elements 4, 5 and 6 fastened U-shaped rams. We are 0, and shields 11. After erecting the walls of the object under construction, the supporting structures — circling 2 by installing connecting elements 12 and 13 (for example, using welding) convert

5 into a single roof structure 3. The roof 3 is attached to the walls of the object under construction, after being erected, to the mortgage elements 14. To prevent distortions and torsion of the formwork during its rise, stabilizers 15, consisting of skis, are installed at the corners of the formwork. and braces 17, bolted to the supporting structures m-circles 2. Displacement stabilizers 15 are in contact with the inner surface of the walls of the object under construction for the entire period of construction, based on the hardened concrete. Suspended scaffoldings 18 are provided on the outer and inner perimeters of the walls for final finishing of the walls of the object being erected. A wooden floor 19 is installed on the upper surface of the formwork and a fence 20 is installed. U-shaped frames 10 have lifting mechanisms 21. The slide formwork is mounted on the lower mark constructed object. After alignment of the formwork and all installation and preparatory work, they proceed to concreting the walls of the object under construction using well-known technology using armature frames installed in the formwork on both sides of the U-shaped frames 10. During the lifting of the sliding formwork, the displacement stabilizers 15 provide the formwork without distortions and torsion. After lifting the formwork to the top of 18 g 14, a new mark of the object being constructed is inserted, the embedded elements 14 are inserted into the formwork, welded to the reinforcement and filled with concrete. After the concrete has hardened by welding, the trusses 8, which are part of the supporting structures — are circled 2 and are part of the bulk roof blocks 3 with the mortgage elements 14, install connecting elements 12 and 13 between the roof blocks 3 and weld the blocks together, convert them to the roof 3. Then proceed to the dismantling of the formwork elements that are not part of the roof 3 of the facility being constructed. The dismantled formwork units are reused as part of the sliding formwork during the construction of the next object under construction. The introduction of sliding formwork of the proposed construction allows to obtain an economic effect by reducing the metal and labor costs for manufacturing the formwork and roofing of the object under construction, reducing labor costs for installation and dismantling works during the construction of monolithic reinforced concrete, as well as improving the quality of concrete work.
