Description

The method for building a high-rise building is as follows.

A foundation pit is prepared in the form of a weakly conical funnel, and a foundation 1 for the core is arranged in its lower part. Then, core 2 is erected in sliding or adjustable formwork. After that, a package of conical support elements 3 is concreted on the surface of the conical trench around the core, equal to the number of raised sections of buildings. On the first support element from above, the crane 4, which moves along an annular rail track 5 or on a crawler track around the core, collects structures (frame, panel or combined) of the first lifted section 6, consisting, for example, of 7-8 floors, and all plumbing, finishing and other works, or they prepare on the floors everything necessary for the performance of these works after lifting.

In parallel with this, the upper support element is wrapped with a prestressed reinforcement 7 and protected by gunning. Upon completion of these works, the supporting element, on which the multi-storey section of the building is mounted, is connected to the lifting taps located along the perimeter of the core 2, the ready section 6 is raised together with the supporting element 3 to the design position and fixed on the core consoles 8, incorporated in the draw when it is built. This process is then repeated for each subsequent high-rise section. The last section (stylobate) is erected on self-contained foundations at the level of the planning level and serves as an entrance hall. The number of floors in it may be less than in the raised sections.

The lifting of the sections can be carried out with the help of t hydraulic lifts mounted on the top of the shaft.

The support element 3 is a reinforced conical shell at the apex with a slope of generatrix to the horizon in the range of 20-30 °. The lower hole, corresponding to the outer diameter 2, is bordered by a steel channel to which the lifting rods are attached. After the upper edge of the building section, the supporting element is wrapped around the upper edge with prestressing reinforcement channels 7, to give it rigidity and strength when lifting and in the design position under load from the multi-storey section of the building.

Rotary consoles 8 are laid around the core perimeter in an amount determined by calculation depending on the weight of the raised sections. During erection

The core and the lifting console are recessed into the walls of the core. After installation of section 6 by the sonor element 3 to the design position of the console, turning, protrude

face the walls of the core and take on the load from the raised section of the building. After that, the rods are lowered down to attach the next support element to them with the next multi-storey section of the building.

The fastening of the raised sections to the other may be different, for example by welding the support element to the embedded parts of the core, etc. The described method of building a high-rise building can significantly reduce the metal consumption, labor intensity and construction time due to the replacement of rigid steel beam cells used in prototype to overlap each

floors, compressed prestressed concrete conical support elements, which are assembled and raised along the other sections of the building height, for example, 7-8 floors. The number of multi-storey sections lifted alternately, and therefore the total height of the building, is determined only by the bearing capacity, i.e. its diameter, wall thickness, brand of concrete and reinforcement, and they can be accepted by any, necessary by calculation with minimal steel consumption. To save concrete, the thickness of the core walls as the load decreases may decrease upwards due to internal ledges. Common

The height of the building does not depend on the load-carrying capacity of the devices raising the individual sections, since the sections are raised alternately. Installation of all sections at ground level is straightforward, and consumption

materials in the section does not exceed that in the building of the same height, built at zero.
