Description

one

The invention relates to the construction, in particular to formwork for concreting floors in buildings with prefabricated walls.

Slab formwork can be used in the construction of reinforced concrete floors and roofing in buildings with walls, such as monolithic reinforced concrete, built into sliding formwork.

Known formwork for erecting interstitial floors of buildings from a concrete mix, including a formwork platform, a suspension device and a supporting part ij

The disadvantage of this formwork is. the complexity of its service and the need to install additional scaffolding,

The closest solution to the invention of which it is known is the formwork of floors concreted in buildings with led walls, including hangings on hangers and supporting devices located above the concrete floor 2.

The disadvantage of this formwork is the lack of mechanization of the stripping oreration, which increases the labor costs for its installation and dismantling.

The aim of the invention is to reduce labor costs for the installation and disassembly of slab formwork.

This goal is achieved by the fact that, in the proposed shuttering form, each of the supporting devices is made in the form of a plug fixed in the mounting hole of the wall, and a hinged bolt interacting with it, pivotally connected to the suspension.

FIG. 1 shows the proposed formwork overlap, general view; on phage, 2. supporting device.

Shields 1 ceiling forms are installed between the finished walls 2 of the building being erected on suspensions 3.

The formwork kit includes a support device 4, which serves to fix the formwork site in a predetermined position, supported by the walls, and provides for the separation of it from the molded floor.

The support fixture consists of a fork 5, fixed in a hole in the wall at

using two brackets 6 and a nut 7, a rod 8, which serves as a suspension for the shields 1, with which the hinged bolt 9, which fits into the PLAN slot and supports it with a spherical

ishiba

On the hinged bolt, below the slot of the fork, a second set of nuts is screwed - a spherical washer 11, by rotating it through the stop towards the end of the fork,

force required to detach the shield from betan.

The work with the formwork is carried out as follows.

For concreting floors, the boards are lowered to the desired position using jacks 12. Four plugs are installed on each shield.

Rotation up уп of g & 10k 10 provides accurate ({shchatsi shield in a horizontal position for the placement of reinforcement and concrete.

After the overlap was molded, screwing in the nut 1O-up and applying the nut 11 to the stop creates a force to break the shield from the concrete, after which the folding bolt 9 is rejected for the POSSIBLE g / g, /

STEPS further lower the shield to the next overlap mark. Then the cycle is repeated.
