Abstract

Use: construction, installation, construction of multi-storey buildings. SUMMARY OF THE INVENTION: A method for erecting a multi-storey building by lifting floors includes the operations of constructing a foundation, one or more cores, making floors at zero or below elevations, and alternating elevating ate along the core of rigidity to the design elevation. When exposed to a stiffener core, its supporting surfaces form on the outer surface, and after its erection, a stepper lift is mounted at the base with hingedly attached to its carrying area paired retractable stops. Each floor is manufactured on the carrier platform of the stepper lift, and the floors are lifted by alternately re-drawing each of the sliding stops with lifts to the support platforms of the stiffener and then moving the elevator downwards after each lift and securing the floor to the corresponding support platforms of the stiffening rod. 8 il. № С

Description

The invention relates to the construction and can be used in the construction of multi-storey buildings by the method of lifting floors.

The closest to the invention to the technical essence and the achieved result is a method of erecting a multi-storey building by raising floors, including building a foundation, erecting at least one core of rigidity, making floors at zero or below marks and alternately lifting them along the core of rigidity to the design mark.

The disadvantages of this method are the increased complexity and construction time associated with the need to install the lifting mechanisms on the head of the rigidity core, as well as the impossibility of fully arranging communications in the core of rigidity before the end of the lifting of all floors due to the need to dismantle and lower the lifting mechanisms, the inability to manufacture work on the manufacture of floors under adverse weather conditions.

The purpose of the invention is to reduce the labor intensity with the reduction of mounting equipment.

The goal is achieved by the fact that in the method of erection of a multi-storey building by raising floors, including building the foundation, erecting at least one stiffener, making floors at zero or below elevations and alternately raising them along the stiffener to the design elevation support platforms form on its outer surface, and after erecting a stiffening core at its base, a stepper lift is mounted with hinged pull-out arms attached to its supporting platform In this case, the manufacture of each exhaust is carried out on the carrier platform of the lift, and the rise of the floors is done by alternately re-drawing each of the sliding stops of the lift to the support platforms of the rigidity core, followed by moving the lift downward by reversing the lift of each lift and securing the floor to the respective support platforms of the core stiffness

FIG. 1 shows a building with several drastic stiffnesses constructed by the proposed method, general view; in fig. 2 - roof construction at zero or below marks; in fig. 3 and A - the rise of the roof structure with a stepper lift along the bone with re-drawing of its sliding stops on the upstream supporting platforms; in fig. 5 - fastening of the roof structure at the design mark and reverse movement of the stepper lift; Fig 6 - manufacture of the upper floor at the zero mark; Fig, 7 - the rise of the upper floor to the design mark; in fig. 8 - fixing the floor at the design mark and the reverse movement of the stepper lift,

The method for erecting a multistory building is as follows.

After the installation of foundation 1, for example, from monolithic reinforced concrete, one or several cores 2 rigidity are erected depending on the architectural solutions and sizes in terms of the building being erected, from monolithic reinforced concrete in sliding or adjustable formwork (not shown). Simultaneously with the construction of the core 2, stiffnesses are formed on their surface 3. Support platforms 3. Then, in the basement 4 of the building being erected, one or several stepper lifts 5 are mounted, depending on the number of stiffnesses 2, having on their supporting platform articulated paired retractable supports 6. After that on the ceiling 7 basement part 4 and on

the supporting platform of the stepper elevator 5 manufactures the roof structure 8 and lifts it to the design elevation by stepping elevator 5 by alternately re-drawing (stepping) its retractable stops 6 onto the upstream supporting platforms 3. Upon reaching the design elevation, the roof construction 8 is fixed on the core 2 stiffness and production t reverse movement down the stepper lift 5 from a step-by-step re-drawing of its retractable stops 6 to the downstream supporting platforms 3 to lower it to the level of floor construction . Next, floors 9 are fabricated sequentially from the top to the bottom of monolithic reinforced concrete, including finishing works and installation of engineering equipment and communications 10

(heating, electricity, ventilation, etc.). After completing the arrangement of each floor and setting the required strength for it, it is lifted to the design mark by a step-lift 5 in the described way, fixing the floor on the support platforms 3 of the rigidity core 2 and lowering the step-lift 5 to the level of floor construction, then the process is repeated the required number of cycles ,

depending on the number of floors of the building.

When the building is erected under adverse weather conditions, the floor manufacturing area is covered with a sliding cover.

Since all the work on the device of the floors is carried out below, the connection of the finished floor to the communications, placed in the core of rigidity 2, is made after fixing each floor to the design mark.

The method of erection of multi-storey buildings provides the ability to carry out various floor layouts.
