Description

Field of technology

The utility model refers to the supporting structure of the dome and is used in the construction of facilities for performing and circus arts, to cover existing buildings, archeological sites, cultural monuments, areas with specific vegetation and many others. It aims to protect from environmental influences. without being affected by the metal structure of the supporting structure.

BACKGROUND OF THE INVENTION

Load-bearing structures of roofing structures are known, made of pylons vertically located in the inner space of the structure with a supporting structure of a dome mounted on them. Located in this way, the load-bearing structure disturbs the vision of the interior space and prevents the use of the entire covered area.

A load-bearing structure CN 2725437 Y of a tunnel-type tent is known, representing parabolic arches arranged and mounted one after the other, built of tubular trusses, the construction of which is not applicable for covering areas of large size and height.

Technical essence of the utility model

The task of the utility model is to create a supporting structure of the dome to cover areas of large size and height, with a simple and reliable design, which at the same time provides rapid handling during installation and dismantling and the interior remains intact from the structural elements of the supporting structure.

This problem is solved by a supporting structure of the dome, built of parabolic arches consisting of tubular trusses.

According to the utility model, the supporting structure of the dome includes a vertically positioned central parabolic arch, on both sides of which symmetrical and inclined outwards relative to the central parabolic arch are located lateral parabolic arches. The central parabolic arch and the lateral parabolic arches are connected by steel ropes.

Parabolic arches are composed of series-connected structural modules of tubular trusses, the cross-section along the entire length of which has the shape of a triangle with a vertex located at the top of the parabolic arch.

The structural modules of tubular trusses at both ends of the central parabolic arch are connected by straight supporting modules of tubular trusses, and the structural modules of tubular trusses at both ends of each of the side arches are connected respectively by inclined to the left supporting modules of tubular trusses and with right-angled support modules of tubular trusses determining the inclination of the lateral parabolic arches.

The cross-section of the truss support modules on the side of their connection with the structural truss modules has the shape of a triangle, identical to the cross-sectional shape of the structural truss modules.

The connection of the structural modules of the tubular trusses to each other and to the supporting modules of the tubular trusses is made by a flange connection at the top of the triangular cross section of the tubular trusses located at the top of the parabolic arch and by two hinges at its other ends.

Each support module of tubular trusses is hinged to the foundation heel.

The advantages of this utility model are:

- Simplified construction, significantly reducing construction costs by 45%, where 75 t of metal is required to cover an area with a diameter of 50 W in a standard load-bearing structure with pylons and only 40 t of metal in the construction of this utility model.

- Ensuring that the interior space under the dome remains intact by the structural elements of the supporting structure, which allows the entire covered space to be used without impairing visibility, and which improves the visual perception of all possible stage performances,

3967 Descriptions to utility registration certificates № 05.2 / 29.05.2020 conducted under the covered space, makes it possible to cover cultural and archeological sites without their contact and destruction by metal pylons located among them, as well as makes it possible to cover rare wood and plant species, without their contact and destruction by pylons located in close proximity to their roots.

- Easy and fast installation and dismantling of finished modules.
