Description

The invention relates to the construction and can be used as a framework for folding cover, lightweight, mobile structures such as yurts, structures of onion domes.

Known is a net dome covering formed by flexible, heterogeneous rods curved along two or three different-level systems of diagonals that are symmetrical with respect to the meridian and located on the circumference of equal radii.

The closest technical solution to the invention is a folding frame of the retina of rotation, including quadrangular cells formed by hinged interconnected continuous, elastic-flexible rods located along the geodesic lines and locking the working position.

The disadvantages of this technical solution are the low performance and the impossibility of creating a bulbous coating, as well as the difficulty of adjusting the curvature and stresses in the frame and the complexity of its folding.

The aim of the invention is to improve the performance by adjusting the Curvature and stresses in the frame of the onion cover while simplifying unfolding.

The goal is achieved due to the fact that in a folding frame of the retina sheath rotation, including elastic-flexible rods interconnected in length to form quadrilateral cells, and clamps of the working position, it is equipped with upper and lower rings and radial rods, the upper ends of the frame rods are rigidly clamped on the upper ring, and their lower ends are pairwise pivotally connected to the ends of the radial rods, the other ends of which are pivotally attached to the lower ring for folding inside

shells of rotation, with the length of each radial rod being less than the maximum radius of the shell in the working position, and the latches are made in the form of flexible connections with tensioning devices and are connected by ends with an upper ring and a base.

FIG. 1 is given a folding skeleton of the retina sheath, bulbous in working position, side view: in FIG. 2 - view of the frame from above; in fig. 3 shows the frame in the folded state, top view, in FIG. 4 shows the mounting of the upper ends of the rods, top view; FIG. 5, the same; side view; FIG. b a node connecting the lower ends of the rods with radial rods; Fig 7 is a bottom view of the frame; in fig. 8 — joint assembly of pivotally connected rods

The folding frame of the mesh shell of rotation (1) is made in the form of spiral-cyclically arranged in two directions around the axis of the adhesion (2) of hinged (P) at the points of intersection of elastic-flexible rods (4, 5). Each rod bends in douh planes and forms a spatial network, the surface of which is negative (6). positive (7) and zero (8) Gaussian curvature. The rods are made of round profile made of fiberglass or metal.

The upper ends of the rods (4) are rigidly clamped by metal clamps (9), on the rigid upper ring (10) For better compression and reliability in operation, the upper ends have elastic tubular nozzles (11) between the nozzles (11) and the clamps (9) around the perimeter of the ring (10) establish elastic shells (12) The upper ring (10) is cylindrical with such a diameter that the ends of the rods with nozzles are rigidly clamped by tightening the clamps (9) between the outer surface of the ring, between themselves and the liners. In this case, the ends of the rods may be located along inclined planes relative to the axis of rotation. The lower ends of the rods have metal tubular nozzles (13) and are hinged in pairs with cylindrical hinges (14) at the ends of the radial rods (15) The opposite ends of the radial rods are fixed by cylindrical hinges (16) on the lower ring (17) The lower ring (17) is made from the tubular profile corresponding to cylindrical diameter hinges. The hinge joints along the length of the rods (4,5) are made in the form of clamps (18) with locking nozzles (19) on the rods.

In order to increase spatial rigidity, the frame (1) is made with horizontal connections (20) in the form of guy cables.

To simplify the manufacture and transport, the rods (4,5} on the annular section (8) of the surface with zero Gaussian curvature can be made detachable and join in a equal strength tubular connection (21). Retaining clamps (22) are attached to the upper ring (10). flexible connections with tensioning devices (23).

The frame is assembled and manufactured at the factory and delivered to the construction site when folded.

Roof filling is mounted in the various phases of opening and stressing of the frame, which in the working position provides additional rigidity.

designs.

The nodes and elements of the frame are simple, of the same type and can be made of various materials (metal, wood, reinforced plastics and

elastomers).

The assembly of the frame (1) is as follows.

Previously on the work site before vertical mounting rods (4,

5) fit in a one-to-one tubular connection (21). In a horizontal position, outwardly from the inside of the frame of the lower central ring (17) with radiator rods attached to it (15), the framework unfolds and folds. Then, securing the latches (22) to the anchors (25) of the independent base, install the framework in a vertical position with the support

on the central lower ring (17). Due to the elastic flexibility and curvature of the rods, the design of the nodes, the tension of the retainers, the pressure of the support on the central lower ring, from which the stresses are evenly distributed along the radial rods and transferred to the lower ends of the bent rods, the framework is evenly opened.

If tension clamps (22) are evenly tensioned with tensioning devices (23). moving the center lower ring (17) and the radial rods (15) to a horizontal position, the installation

frame in the working position, the rods at the same time experience a complex bending and torsion deformation and form a stable spatial system. Due to its lightness and flexibility, the design is seismic resistant.

The shell framework can be used for industrial, civil, religious and agricultural buildings and structures.

It is also advisable to use the structure in remote northern areas as a mobile frame of a type a yurt dwelling, with the possibility of adjusting its height, volume and curvature to allow heat and air exchange to be controlled by the external environment to create maximum comfort. In addition, bulbous forms conform to national traditions in architecture.
