Abstract

METHOD OF CONSTRUCTION OF CONSTRUCTIONS BY THE RISING METHOD, including the installation of columns with lifts and cargo trails, the manufacture of a package of floor slabs and a roofing slab with their subsequent elevation to design marks, in order to ensure the construction of a structure in a height-limited area by lifting the roof slab and the upper slab to the design elevations. The lifters are dismantled and installed under the cradle slab, while between the last and the upper slab from two the sides of each column establish inventory racks with a height to the floor, grip the upper e slab and at the same time lift it up (take it and the roofing slab to the design marks.

The invention relates to construction, in particular, to methods for erecting a structure by the method of lifting into underground space.

The known method of erection of structures, including the manufacture of core stiffness on the entire height of the building, installation of columns, concreting the package of floor slabs with the subsequent rise of 4 to design marks l.

There is also known a method of erecting structures by the method of lifting, including the installation of columns with lifts and cargo mills, the manufacture of a package of floor slabs and a roofing slab with an elevation of 4 to design marks 2.

A disadvantage of the known injuries is that the erection of structures in the underground workings is associated with large losses in height, since in order to lift the blood slab to the design elevation, it is necessary to take inventory (temporary) columns for the installation of elevators on the tops of the columns. , thereby thereby allowing the last hole in the column to be installed on the design elevation of the roofing slab. In addition, the lifts installed on the inventory columns must have a free-wheeling capacity of the cargo trucks, which leads to a large noTep.-iM of the built-up underground volume.

The purpose of the invention is to provide the possibility of erecting a structure in a space limited in height.

Purpose is achieved in that according to the method of erection of buildings, including the installation of columns with lifts and cargo trucks, the manufacture of a package of floor plates and a roof plate and their subsequent rise to design marks before lifting the roof and top floor slabs to the design marks the lifts are dismantled and installed roof slab, while between the last and the top slab on both sides of each column set the inventory rack height on the floor, b atm upper plate overlap and simultaneously raise it and krovelnuyu plate on design marks.

FIG. 1 shows schematically: installation of columns, production of a package of floor plates and a roofing plate, installation of lifts with cargo weights and the capture of the roofing and underlying slab; in fig. 2 - the rise of the roofing and underlying slabs to the appropriate mark and the seizure of the following underlying slabs; in fig. 3 - the floor slab has reached its design level; in fig. 4 - the floor slab reached the second floor. of its design mark and roofing slab, the rt of the underlying slab is separated to the height of one floor, and the lifts are dismantled and mounted on columns under the roofing slab; Fig. 5 shows the installation of the roof of the roofing and underlying slab on both sides of each column of the inventory racks and the grip of the underlying slab; FIG. 6 shows a parallel lift with installation of the roofing and underlying slabs on their design marks.

The method of erection of the building by the method of lifting is carried out in the following sequence: after the installation of columns 1, the construction and manufacture of a package of floor slabs 2 and roofing slab 3 install lifts 4 with cargo drafts 5. Next, the floor slabs are lifted by the usual The plates 3 into the design position of the lifts 4 are dismantled and installed on the columns under the roof slab. And yyezh at. roof 3 and the underlying slab 2 overlap on both sides of each column establish inventory counters b. Next, lifts 4 grip the underlying slab 2 and produce a parallel lifting of it and the roofing slab 3 with the mills - J koy to their design marks. Then inventory racks 6 and 4 lifts dismantled.

This method allows the maximum use of the volume in underground expressions due to the fact that the lifting equipment is installed under the roofing slab and it is possible to maximize the rise of the blood plate to the ceiling of the underground excavation by the amount of the required design clearance.
