Abstract

The device is intended for erection of a round structure in the plan, intended both for newly built objects, and for repair and restoration and finishing works. The aim of the invention is to simplify the design and reduce the material consumption of the device. An annular guide is attached to the outer wall, which has reinforced concrete with the console, fixed it to the wall. The guides on the rolling elements mount the trusses on which the composite girders are laid, the height of the latter is regulated by wedge-shaped gaskets. Metal trusses are laid on metal trusses, the upper part of which has the outline of a vault. 4 il. (From sl 00 to x 00 05

Description

The invention relates to the construction and can be used both in arranging overlappings and covering large-span round-shaped outlines in the plan, as well as for repair and restoration work using mobile formwork consisting of trusses.

The purpose of the invention is to simplify the design and reduce the material consumption of the device.

FIG. Figure 1 shows schematically the construction plan; in fig. 2 is a section A-A in FIG. one; in fig. 3 shows the node I in FIG. 2; in fig. 4 - truss with a wedge-shaped device, runs and dome dome, section.

The device consists of an annular guide 1, on which the rolling elements of the truss 2, diagonal braces 3 between the trusses 2, a reinforced concrete console 4 on which the annular guide 1, wooden or metal girders 5, stacked on the truss, wooden (metal) flooring - formwork 6, stowage 7, wedge-shaped gaskets 8, reinforced concrete ca 9, a mobile device in the form of a winch 10, a monolithic reinforced concrete arch 11, waterproofing 12, a farkopf 13, a hook 14 and lock nuts 15.

The device works as follows. .

An annular guide is arranged on the outer wall, which has reinforced concrete with a cantilever, on which a metal truss rests, at the top of which a wooden or metal formwork is installed.

The formwork has an upper outline the same as the outline of the designed reinforced concrete arch.

Wooden or metal wedge-shaped gaskets are installed between the truss and the formwork as a regulating device between the parts (Fig. 4). Thus, the release of the concreted vault element from the formwork is accomplished by removing the wedge-shaped gaskets from the girders. The formwork has a width of 5-6 meters, i.e., monolithic reinforced concrete roof with a width of 4-5 meters can be concreted at a time.

After concreting the roof onto reinforced concrete, the arising effect

the force of its own weight, and for its perception, reinforced concrete is forced beforehand (before concreting) the diametrically is tightened with a metal tightening.

The shaking is carried out as follows.

The metal girder at both ends of the lower band (Fig. 3) has a hook to which a farpof with an inventory pin is attached and tension is pulled, resulting in a hook. This creates a strong bond between the concrete in the diametrical direction. After the concreting is completed and the concrete strength of the reinforced concrete roof is achieved, the tension is relaxed with the help of the tow bar. The farm is vacated.

The second stage of the concreting of the roof is carried out by perpendicularly concreted parts. In order to perceive the arising (horizontal) force, an analog device is arranged in the described sequence.

The subsequent concreting of the sectors is carried out by moving the truss around its axis in the appropriate direction with the help of a winch.

Claims (2)

1. A device for erecting a domed dome of a circular structure in terms of, including a supporting structure installed in the upper part of the walls of the structure and a formwork fixed to them, characterized in that, in order to simplify the design and reduce its material consumption, the device is equipped with a ring guide, fixed at the upper end of the walls of the building, and girders, and the supporting structure is made in the form of a diametrically located truss, us-. mounted on an annular guide using rolling bearings and having fixtures for fixing it in the working position, with the fixings being passed through the holes formed in the walls of the building and fixed on their outer side, and the runs are made in parts which are wedge-shaped gaskets. 2. The device according to claim 1, about tl and is often due to the fact that the farm is made of a composite of the same type of elements. / / / / / 2 fuy. / Yu X /five / -V / / / X Aa 11 12 15 U9. 2 P / 7 /// 7777 // 7 / //// 7 /// // 7 ///, / Fiyo 3 P T ff / i / Vi lm  8 5 iJOwe ..
