Description

one length of which is greater than the size of the gap between the plate and the wall, and with horizontal key projections 7.

Before lifting the top plate of the floor package, inventory split collars 8 with wedge-shaped elements and step lifts 9 with elastic supports and wedge-shaped grips are installed and fixed into the girth of the racks.

Then the lifts 9 are connected to the system for ensuring uniformity of lifting and the lifting of the slab begins. Due to the presence of 9 wedge-shaped grips and elastic supports in the elevator, and wedge-shaped elements interacting with the stand in the collar 8, the lifting is carried out cyclically with alternating self-jamming and self-wedging of them on the stand. In the process of lifting the upper slab, when it reaches a height of 2-2.5 m above the package of remaining slabs 5, the next set of inventory collars and lifts is installed on the top of them and the slab is lifted in the same way, all the remaining slabs are subsequently introduced into this process.

When all slabs reach the design elevations, the lifts are removed, the reinforcing bars 6 are unbent and inserted into the grooves, after which the gaps between the edges of the floor slabs and the walls are concreted to fill the grooves. After acquiring the abutment portions of the plates thus formed, the design strength of the strut 4 and the foundations 3 is removed. The holes in the floor slabs, after removing the inventory racks, are closed.

The method allows you to create buildings (structures) by the method of lifting with ceilings without intermediate supports, limited only by the end, which ensures the integrity of the architectural and operational volume of the premises between the bearing walls. This allows you to use the method not only for the construction of new buildings, but also for major repair and restoration, in particular, of historical buildings in which any change in the internal architectural and planning decision is unacceptable.

All auxiliary structures involved in the process of lifting floors

(racks and foundations for them, detachable collars, etc.) are inventory, which allows them to be used along with lifts many times, thereby reducing construction costs.

For major repairs, including restoration, the claimed method allows full use of the bearing capacity of previously constructed walls and

foundations.

Formula a from the invention 1. The method of construction of a building, construction by lifting floors, including the installation of racks, manufacturing on

the ground of the package of floor slabs, installation on the upper plate by means of elastic supports of stepper lifts with wedge-shaped grips, discrete rise of the plate with wedge-shaped elements,

interacting with the uprights, and sequentially turning on the remaining floor slabs during the lifting process with installing on each of them another set of lifts, characterized in that,

in order to expand the scope of use by providing the possibility of using frameless buildings with pre-erected load-bearing walls in construction, to reduce construction costs, racks are made in inventory, and they are installed on temporary foundations in the space between walls in which horizontal marks are made at the marks of floors , floor slabs are made with bent reinforcing rods released from the edges, the free length of which is greater than the distance from the edge to the wall, to inovidnye elements

They are placed in detachable inventory collars, which are fixed on each plate before it is lifted, when the plates are brought to the design position, the reinforcing bars are unbent, and they are turned into shrabs and without

the gaps between the edges of the slabs and the walls are tinted to fill the walls, and after concrete reaches the specified strength, inventory collars, racks and temporary foundations are removed.

2. A method according to claim 1, characterized in that the vertical surfaces of the edges of the floor slabs are made with horizontal keys.
