t

The esabretation refers to construction.

There is a known method for the formation of interfloor overlappings, including the installation and installation of wooden formwork over the entire area of overlap, the installation of reinforcement, concrete filling and the removal of concrete.

A disadvantage of the known technical solution is the increased labor costs for the ceiling device.

There is a known method for the formation of interfloor overlappings, which includes the execution of a monolithic slab at the ground level and its subsequent elevation to the design of mercury 2.

A disadvantage of the known technical solution is the increased complexity of performing the overlap.

The closest to the proposed "Omu" is a method for the formation of a single-storey overlap, including installation of solid pillars on support 6ai poppy, installation of working formwork and construction site, concreting and installation of Formwork, and a device for implementing the method, containing working formwork on the safety net, telescopic stands with a mechanism of imi displacement and support shoes h.

The purpose of the invention is to simplify the production technology.

The goal is achieved by the fact that in the method of formation of interfloor overlappings, including the installation of telescopic racks on support shoes, the installation of working formwork on the building site, concreting and de-building. the installation of the formwork, the working formwork is mounted and dismantled at the level of the underlying overlap, and the telescopic pillars are moved to the overlying overlap by self-lifting through the holes, made in the floor of the process of its concreting. In a device for drying a method for the formation of cushes overlappings, containing working formwork and a safety platform, telescopic racks with a mechanism for their movement and support shoes, the latter are split with a through-hole and liner,

working formwork is mounted on the bottom of the telescopic racks.

FIG. 1 shows the device, a general view; in fig. 2 - installation of the telescopic stand on the support shoe; in fig. 3 - formwork mating with torso & scopic stand.

The device for the formation of interfloor overlappings includes support shoes 1 on which telescopic pillars 2 are supported, from which rods 3 can be mounted. At the upper end of telescopic racks 2, mechanism 4 is mounted for their movement, adjustment screws 5 with rollers 6 and safety platform 7, and at the lower end of the telescopic pillars 2 at the top. support shoes 1 - working formwork 8 and washers 9 mounted on telescopic racks 2 with the possibility of free movement along these CToeic working formwork 8 interconnected with telescopic racks 2 by means of couplings 10.

The support shoes 1 are made split with a through hole 11 and provided with an insert 12 on which the rods 3 of the legs 2 are supported during concreting, and the supporting shoes 1 are interconnected by rigid connections 13.

The formation of interfloor overlap is carried out as follows.

In the previous overlap, the support shoes 1 are assembled, the viewer is mounted in the field and interconnected by rigid connections 13 to provide rigidity in the transverse and longitudinal directions.

A through hole 11 of the shoes 1 is closed with a plug 12 by entering it through a window formed in the wall of the shoes 1.

The telescopic struts 2 put on cone-shaped washers 9, which serve to form the holes 14 in the overlaps 15, and 3; Before betsinirovaniem washers 9 lubricate. In the shoes 1 set the rack 2, on the end of Befi HeWt which are mounted

elevating mechanisms 4, adjusting screws 5 with rollers 6, collect a safety platform 7. With the help of re-fixing .X screws 5 and rollers 6 racks

2, 3 give a strictly vertical position.

At the lower end of the racks 2,3 at the top of the shoes 1 collect working formwork 8.

After assembling the formwork 8 ok I lift

to the design position by moving up the Telescopic uprights 2 and connecting the rods 3. The rods 3 are supported on the shoes 1 by means of an insert 12.

Between the formwork 8 and the wall of the building are installed gaskets with a thickness of 20-25 mm to facilitate the removal of shields. Reinforcement and concreting are performed 15.

After the concrete sets necessary nj) 04HocTK, they lower the pillars 2. from the working cover 8 to the initial position by reversing the lifting mechanisms 4. The conical washers 9 remain in the ceiling 15. The formwork 8 is disassembled, releasing the stands 2 from engagement with it, and making them lift themselves higher the top level of the arranged overlap 15. When lifting the struts 2, the last clutch 10 captures the cone-shaped washers 9 and withdraws I.X from the engagement with the overlap 15.

Support shoes 1 are installed in the girth of the rods 3 on the overlap 15, then the telescopic pillars 2 are supported on the latter by means of ix reversing. The shoes 1 are fixed between each other by rigid connections 13. Then the rods 3 are raised above the level of the upper shoes 1, the liner 12 is inserted into the latter through the window and the rods 3 are lowered onto them. Collect working formwork 8 and the cycle is repeated.

It is possible to first assemble the formwork 8 | and then raising the rods 3 and supporting us on the insert 12 of the shoes 1, it is also possible to carry out both operations simultaneously.

The formwork elements 8 are fed to the next floor through the window of the building or through a hole arranged in the ceiling.

The holes 14 formed in the overlap, which serve to pass the telescopic pillars 2, 3 during the concreting process, are filled with concrete liners, the shape of which corresponds to the shape of conical washers 9, on the cement mortar.
