Description

The invention relates to the construction, in particular to methods of erecting multi-storey frame buildings by the method of lifting floors.

The purpose of the invention is to reduce the labor intensity, simplify and shorten the installation time.

FIG. Figure 1 shows the moment of the manufacture of a package of floor slabs at ground level with prestressing and the installation of a column and lifting equipment; n FIG. 2 - the rise of the floor slabs in the case when the ne: ditch and the second floor slab are at the design elevations, and the columns within the first floor are monolithic from the first floor slab; in fig. 3 - floor slab, plan view; in fig. 4 — node I in FIG. 3 (support plate assembly); in fig. 5 shows section A-A in FIG. four; in fig. 6 - node P in FIG. 2 (the moment when the column armature is passed through the cage); in fig. 7 - unit GP pa fig. 2

The method of erection of a multi-storey frame building by the method of lifting the ceilings is carried out as follows.

After the formation of the foundation I install the pillars 2, on which are placed the lifting equipment 3 with cargo bars 4. Moreover, the pillars 2 are installed on the axis

constructed building. Next, make the slab 5 with cross gaps 6 along the frame axes. In the cross gaps between the upper 5 7 and lower 8 reinforcing springs, metal clamps 9 of the cellular structure with mounting holes 10 are placed with the racks, and the reinforcement is tensioned to the clamps by pressing the corners of the floor slabs. Then, using lifts 3, mounted on racks 2, lift the floor slabs to the design marks, and after the floor slabs have reached the design marks, the longitudinal vertical reinforcement T1 is passed through the cell slots and concretes the space around each rack, forming the columns 12 of the building frame .

From the proposed method of erection of a multi-storey frame building, it will be possible to exclude mon15

these columns, thereby reducing the consumption of metal in the joints of the joining of floor slabs with the columns and reducing the labor intensity during the construction of the building. Due to the use of racks with a height of several floors, the number of column joints is reduced, which also reduces the labor intensity and the consumption of the mecha. Thus, the pre-paving method allows, with the least flexibility of the columns, to have slabs at the design marks with their final fixation with the columns, while ensuring the stability of the structure as a whole.

METHOD OF BUILDING A MULTI-STOREY. FRAME BUILDING BY THE METHOD OF LIFTING OF OVERLAPPING, including the formation of the foundation, installation of racks on which load-lifting equipment with load rods are placed, the manufacture of floor slabs with cross gaps along the axes of the frame through which the upper and lower strand reinforcement are passed Figure 1 and produce its tension, then monopolize the gaps of the floors, and then lift the latter to the design position. With the subsequent formation of the columns of the frame, characterized in that, in order to reduce the complexity, simplify and shorten the installation time, the racks are installed along the axes of the columns being constructed buildings, in the cross-gaps between the upper and lower reinforcing strands, the metal rails of the cellular structure with mounting holes are placed, covering the racks, then they are pressed against the rails by the tension of the reinforcement ly slabs, and after lifting the slabs on design marks longitudinal vertical reinforcement is passed through the cell cages and concreted space around each rack, forming columns of the building framework.
