Description

The invention relates to the construction workers * stvu, in particular to methods for the construction of multi-storey buildings with a core of rigidity by the method of lifting floors.

The aim of the invention is to reduce energy consumption, material consumption of lifting equipment and reduce construction time.

FIG. 1 shows schematically the fabrication of bearing platforms on the ground level with the simultaneous construction of a stiffening core on which a crane is installed; in fig. 2 bearing platforms of the floors, lifted with the help of lifting equipment and 15 fixed on the design elevations of the rigidity core already erected; in fig. 3 - installation of the lifting mechanism on the second carrier platform using a crane located on the 20 core stiffness; in fig. 4 - installation of floors on the first carrier platform using a lifting mechanism mounted on the next second carrier platform; 25

in fig. 5 - assembly of the lifting mechanism at the third carrier platform by a crane, positioned on the core hardness after installation floors on the first carrier platforms of ₀ form; in fig. 6 — node 1 in FIG. five; in fig. 7 - the location of the lifting mechanism on the carrier platform, which is moved with the help of carriages mounted on the $$ ring rail tracks, the plan; in fig. 8 is a section A-A in FIG. 7

The method of erection of a multi-storey building includes the manufacture of a core 40 of rigidity 1, carrier platforms 2, 3, 4, 5 (in FIG. 1, a package of four carrier platforms is conventionally shown).

Next, make installation floors 6 45

on the supporting platforms after they are lifted and fixed on the design marks, the lifting mechanism 7 for mounting the floors of one carrying platform is suspended on the 50 upper platform using mobile trolleys 8, which are mounted on pre-assembled ring rail tracks 9, and mounting and dismounting this mechanism , 55 and also the manufacture of the core stiffness carried out installed on the core stiffness crane 10.

The method of construction of a multi-storey building with a bearing core stiffness method of lifting floors carried out in the following sequence.

The crane 10, mounted in the center of the core of rigidity, is a crane of the aggregate device mounted on a platform, which vertically moves with the help of lifting equipment used in the construction of this building. The lifting equipment is installed on the intra-barrel columns and the platform is suspended by vertical movement, which is fixed on the same columns in the working position.

Shields of formwork are also attached to the platform for concreting the section of the erected core. In this case, the crane 10 provides for the supply of materials (reinforcement, concrete) necessary for the manufacture of core stiffness. And as the stiffening core is erected, the crane along with the formwork moves up along the barrel walls. Simultaneously with the construction of a stiffness core 1 at ground level, a package is cast from the required number of supporting platforms (2, 3,

4, 5). Then using lifting equipment 11 carry out the lifting of the platforms with their subsequent fixing on the design elevations.

Next, on the carrier platform 3, the annular rail tracks 9 are installed, on which mobile trolleys 8 are installed. Then, a lifting mechanism 7 is mounted on the mobile trolleys, and then the floors 6 are mounted on the underlying carrier platform 2 by means of movement as a lifting mechanism 7 along the circular track, and the movement of the carriage 12 on the arrow 13.

After the installation of the floors on the carrier platform 2 is completed, the load-lifting mechanism 7 is moved by means of a crane 10 installed in the center of the core of rigidity to the next overlying platform 4 and the floors are mounted on the underlying platform 3 in the same sequence. After the installation of the floors on all bearing platforms is completed, the lifting mechanism 7 is dismantled using a crane 10.

The proposed method allows

reduce material consumption and energy intensity of lifting equipment,

as with his help on the project

marks only platform platforms are raised, and the installation of floors on each of them is carried out with the help of a lifting mechanism mounted on an overlying carrier plate 1188274 4,

’Form. Therefore, it becomes possible to use widespread lifting equipment with a lifting capacity of 50 tons. In addition,

5 such a method allows installation of floors on two or more bearing platforms at the same time, which significantly reduces the time required to construct a building.
