Abstract

This invention relates to the field of construction. The purpose of the invention is to reduce the labor and material intensity of the process. The method of building walls of cylindrical structures in sliding shuttering is carried out as follows. Vertical reinforcement 4 serves as a guide for horizontal reinforcement in the form of closed rings 6, which are pre-secured on the jacking frames 2. After the first layer has been laid, the annular reinforcement 6y freely moved along the vertical reinforcement 4, is installed in the design position and subsequently loaded by a sizing concrete . 1 il. o 5 w tL

Description

The invention relates to the construction of monolithic reinforced concrete structures and concerns the use of sliding formwork for building cylindrical walls.

The purpose of the invention is to reduce the labor and material intensity of the wall construction process.

The drawing shows a wall of a cylindrical structure erected by the proposed method, a vertical section.

Formwork 1 is attached to jacking frames 2, on which piles 3 with vertical reinforcing rods 4 wound in them and a cartridge 5 for storing and delivering horizontal working reinforcement in the form of rings 6, and concrete laid in a wall with layers 7, which are equal to the pitch of the horizontal reinforcement, using a dispenser 8.

The method is carried out as follows.

In the process of lifting, the split of the slab formwork 1, which is attached to the jacking frames 2, the vertical reinforcement 4, is wound in the shoulders 3, the passage through the guide holes of the cassette 5, tension and leveling, takes the design position and serves as a guide for horizontal reinforcement. The horizontal reinforcement, prefabricated in the form of closed rings 6, in an amount sufficient to erect the entire structure, is temporarily fixed to the jacking frames 2 with the aid of the cassette 5 during assembly of the sliding

formwork After laying and compacting the first concrete layer, the ring reinforcement 6 is installed by freely moving it from the cartridge 5 along the vertical reinforcement 4 with the next loading of the overlaying layer of concrete supplied from the concrete distributor 8. Next, the process is repeated, with the height of the laid concrete layers 7 in the compacted state, it is equal to the pitch of the horizontal reinforcement 6 installed in the design position.
