Abstract

The invention relates to methods for the erection of monolithic reinforced concrete in residential and public buildings. The purpose of the invention is to reduce the material intensity of the molding equipment. In order to achieve this goal, columns 4 and pallets 5 are mounted on foundations 1, onto which an emergency tube 6 is installed, which is loaded with concrete mix 7 and lifted with jacks 3. After the concrete has hardened, the formwork is detached from the concrete and lowered into the lower position. Then the formwork 6 is again filled with concrete mix 7 and lifted with the help of jacks 3, while the previously molded floor 8 is removed from the columns with a force of jacks and pereopiruyut directly on the concrete mix that is in the formwork using the weight of the molded floor. 6 Il.

Description

The invention relates to methods for the erection of monolithic reinforced concrete in residential and public buildings.

The purpose of the invention is to reduce the material consumption of the molding equipment.

FIG. 1 shows the formwork with a concrete mix in the initial position; in fig. 2 shows section A-A in FIG. one; in fig. 3 - formwork with a concrete mix at the time of lifting; FIG. 4 shows a section BB in FIG. 3; in fig. 5 - molded floor, fixed in an intermediate position; in fig. 6 - floor of the building resting on the concrete mix loaded in the formwork.

Foundations 1 are arranged on the construction site, in cells 2 of which jacks 3 are installed. Columns 4 are mounted on foundations 1 so that their vertical axes coincide with the vertical axes of the walls being erected, and pallets 5 on which the formwork 6 is installed is U-shaped .

Concrete mix 7 is loaded into the formwork 6 in the required quantity and, prior to its setting, the formwork is lifted with the help of jacks 3 to an intermediate mark, 1 de is held until the concrete mix is cured. After the concrete has gained the necessary strength, the formwork is detached from the concrete by means of the return stroke of the jack and the jacks are lowered to the lower position.

: Then the formwork 6 is prepared for the installation of reinforcement, window boxes, window pliers and, after the necessary preparatory operations, the concrete mix 7 is again loaded in the required amount and lifted with jacks, while the previously formed floor 8 is removed from the columns with a force of jacks and reapply directly on the concrete mix loaded into the formwork, using the weight of the molded floor 8 to compact the concrete mix. Further, the operations are repeated until the building is erected at the required height. At the end of the construction of the building, the formwork is lowered to the lower position and dismantled together with the pallet, leaving the building supported in a position on the column. If necessary, the building is raised higher than the top of the columns, the latter are removed, and the building is lowered onto the foundation. The tray 5 is removed or left in the body of the wall. The jacks are dismantled at the end of the building.
