Abstract

The invention relates to construction and is intended for building envelope. The purpose of the invention is to increase the holding capacity. The three-layer panel of the enclosure includes two convex shells 1 connected along the perimeter of the rods 2 in the middle layer. The shells have longitudinal and transverse ribs 3, the ends of which are connected by rods 2. The thickness of the shell in the center is 1 / 2-1 / 4 of its thickness at the perimeter. In the manufacture of the panel, an evacuated cavity is created inside, which provides a more efficient perception of external influences, improves the sound insulation and thermal properties of the panel. 3 il.

The invention relates to construction and is intended for building envelope.

The purpose of the invention is to increase the carrying capacity.

Fig 1 shows a panel plan; FIG. 2 is a section L-A in FIG. one; FIG. 3 is a section BB in FIG. one.

The three-layer fencing panel consists of two double-convex shells 1, interconnected along the perimeter. The middle layer of the panel includes longitudinal and transverse rods 2 made of glass or basalt filaments or round steel. The shells are provided with longitudinal and transverse ribs 3, the ends of which are connected in pairs between each other by the rods 2 The thickness b of the shell decreases to the center of the shell to 1 / 2-1 / 4 of its thickness at the perimeter

Metal, carbon fiber, glass or other material with durability, lightness, low thermal conductivity and high manufacturability of its production and further processing can be used to imitate the shells. In addition, it must be well connected to each other, have a small gas release and create a ib tightness of the shell. panels This is necessary to create a sealed cavity of the panel in order to reliably maintain a vacuum in it

The panel is manufactured as follows.

By pressing or hot rolling, shells are made in the material production process. They then arrive at the stand where the longitudinal and transverse ribs, metal rods, glass or basaltic yarn are laid out. One of the known methods, for example by soldering, welding, etc., is connected to each other. This operation can be carried out jointly during pressing or rolling. shells in the process of their preparation Shells and ribs CAN be jointly carried out in the process of izutyvovi shells This is the most rational method, as you can reduce energy, material costs and laboriousness, going to join shells ribs.

Then combine the perimeters of the shells and

tightly, tightly connected by known methods (welding, brazing, gluing), for example, welded with one seam.

The closed cavity thus obtained is checked for leaks using vacuum equipment and, if it is not present, leaks, shells, are removed in h in the welds using known methods. After that, the evacuation of the cavities of the shell of the panels can be performed in two ways: through vacuum

fitting 4 or individually vacuum each panel in the process of its manufacture, or once in the complex of the entire building after their installation and tightly connecting them to each other.

QOffer construction three-layer

fencing panels are a monolithic design that accepts static, dynamic, and other loads and effects, in which all elements work together, increasing the carrying capacity and rigidity of the panel and fencing as a whole.

When evacuating the panel cavity, not only does the heat engineering, soundproofing, and sometimes translucent properties of the panel improve, but uniform compression of the shell of the panel and stretching of the rods that perceive thrust under the influence of external atmospheric pressure on the shell are achieved.
