MULTILEVEL BUILDING DESIGNED BY METHOD

LIFTING FLOORS AND FLOORS

The invention relates to the construction and can be used in the construction of core stiffness in high-rise buildings erected by the method of lifting floors and ceilings.

There is a known method for erecting a stiffener of rigidity of a multi-storey building constructed by raising floors and ceilings in a movable formwork, including the installation of formwork panels, a reinforcement cage followed by concreting the stiffener and the entire height of the building 1.

There is also known a method of erecting the core stiffness of a multi-storey building constructed by the method of lifting floors and ceilings, including the installation of a reinforcement cage and, after lifting the plates to shut off, concreting the walls with openings of the core of stiffness after lifting the floor slabs (2).

A disadvantage of the known solutions is that a lot of metal is consumed for the manufacture of a core. In addition, with such a sequence of rigidity erection, construction time increases.

The purpose of the invention is to reduce the time of the construction of a stiffening core while reducing its material intensity.

The goal is achieved by the fact that in the method of erecting the core of rigidity of high-rise housing. built by the method of lifting floors and floors, including the installation of a reinforcement cage, and after lifting the floor slabs floor concreting of the walls with openings of the reinforcement core, prior to installing the reinforcement cage along the edges of the openings, prefabricated reinforced concrete columns with consoles that orient towards each other are installed, after what the columns are combined into a closed spatial system with assembly connections, which are dismantled in the process of floor concreting of walls.

FIG. 1 depicts the manufacturing process; nor the string of rigidity during the installation period; .on FIG. 2 - unwrapping the walls of the core of rigidity during the assembly period; in fig. 3 - the process of concreting the main core; in fig. 4 - unwrapping the walls of the core in the process of concreting from bottom to top.

The method for erecting a stiffening core of a multi-storey building is carried out as follows.

Before installing the reinforcement cage, but the granules of the core I stiffness openings install prefabricated reinforced concrete columns 2 with reinforcement outlets 3 and with console 4, which also have reinforcement outlets 5, with the cantilevers 4 prefabricated reinforced concrete columns oriented towards each other. Thereafter, the columns 2 are combined into a closed spatial system with mounting links 6.

Thus, in the assembly period of the building, spatial stiffness is formed using precast reinforced concrete columns 2 and inventory assembly links 6, Next, the reinforcement cage / main stiffener and reinforcement cage 8 peremychek (above the openings) are installed, which are respectively connected to the reinforcement outlets 3 columns and with reinforcement releases 5 consoles. Then, floor-by-floor concreting of the stiffener walls starts from the bottom up, and when the concrete gains the necessary strength, the inventory assembly links 6 are dismantled.

With the proposed method of erecting a stiffener, the erection time is significantly reduced due to the fact that the erection of a core during the installation period is much ahead of the building frame. In addition, the use of basic building materials (metal) is significantly reduced through the use of assembly inventory links.
