Description

one

The invention relates to the construction, in particular to methods of erecting buildings by the method of lifting floors and floors.

There is a known method of erecting a multi-storey building, which includes the installation of building columns, the manufacture of a package of floor slabs and a shaft, the installation of lifts with cargo bars on the columns of the building with the subsequent lifting GH.

The closest to the proposed technical solution is a method of erecting a multi-storey building with a bearing reinforced concrete shaft with a rigid reinforcement cage and openings, including the installation of building columns and a rigid reinforcement cage of the mine, a package of floor slabs and a shaft, installation of elevators with cargo weights on the columns and the mine building with a phased rise of floor slabs and their installation in the design position and concreting of the mine 2.

A disadvantage of the known technical solutions is the complexity of the building erection technology, which increases the construction time.

The purpose of the invention is to simplify the construction of the building and reduce construction time.

This goal is achieved by the fact that

the method of construction by the method of lifting, floors and floors of a multi-storey building with a bearing reinforced concrete shaft with a rigid reinforcement cage and openings, including the installation of columns

building and rigid reinforcement cage of the mine, the manufacture of a package of floor slabs and mines, the installation of lifts with cargo tons of ga.mi on columns and the mine building with a phased

the lifting of floor slabs and their installation to the design position and concreting of the mine, simultaneously with the installation of the columns of the building and the rigid reinforcement cage of the mine in the field of openings

Claims (2)

the latter are installed vertical metal poles, which are connected to the shaft frame, and in the manufacture of floor slabs and shafts, they are interconnected by horizontal ties, then in the places of the openings of the shaft on the vertical metal poles install mobile frames for lifts with traction which are placed at the level of installation of lifts with traction on the columns of the building, and the tows of lifts in the mine are installed in the plane of its walls, and when lifting the floor slabs they are fixed to horizontal connections. At the same time, to ensure the spatial rigidity of the shaft during the period of staging, the vertical metal columns are connected by additional connections. In FIG. 1 shows a building plan; in fig. 2 shows section A-A in FIG. 1. The method is carried out in the following sequence. Simultaneously with the installation of the columns of the building 1, vertical metal posts 2 are installed, which are connected to the frame 3 of the shaft 4. Then floor slabs 5 and the slabs 6 of the shaft are made, which are connected by horizontal links 7, then in the places of the shaft openings on its metal racks 2 install movable frames 8 for lifts 9 with thrusts 10, which are placed at the level of installation of lifts 11 to. buildings, and the lifts 9 with t gami 10 are installed in the plane of the mines. When lifting the slabs, the gates 10 are fastened to horizontal ties 7. After the slabs come to their design marks, the concreting of the shaft begins (in the mine drawing, conventionally shaded by). During the period of installation, in order to ensure spatial rigidity, the vertical metal posts 2 are joined by additional connections 12. The proposed method allows to significantly reduce the construction time and significantly reduce the workload of the work, since the floor slabs of the floor are simultaneously raised. At the same time, construction time is significantly shortened, since the metal structure of the mine is erected with considerable advance and allows lifting and assembly work to be carried out freely (lifting of the floor slabs) In addition, new mobile frames ensure the joint spatial work of the mine to absorb wind loads during the erection process. Claim 1. Instruction method of raising floors and floors of a multi-storey building with a supporting shaft with a rigid reinforcement cage and openings, including the installation of columns of buildings and rigid reinforcement cage, making a package of floor slabs and shafts, installing lifts with cargo bars on pillars and a building mine with step-by-step lifting of floor slabs and installing them into the design position and concreting the shaft, characterized in that simplifying the building erection technology and reducing the construction time, simultaneously with the installation of the building columns and the rigid reinforcement cage of the mine, vertical metal posts are installed in the places of the openings, which connect with the mine frame, and in the manufacture of floor slabs and shafts, they are interconnected by horizontal ties, then in the places of the mine openings on the vertical metal racks install mobile frames for lifts with drafts, which are placed at the level of installation of lifts with trays on the columns of the building, and the gantries of the lifts in the mine are installed in the plane of the ep walls, and when lifting the floor slabs they are fixed to horizontal connections. 2. The method according to claim 1, characterized in that, in order to ensure spatial estkosti shaft during mounting, vertical metal posts combined additional bonds.
