Description

The utility model relates to heat and sound insulating panels used in industrial, civil engineering and various industries.

A sandwich panel with a honeycomb filler is known, containing two surface layers and an inner layer that is equally spaced between them and consists of honeycomb cells in the form of regular hollow prisms with hexagonal bases facing the surface layers. (Patent for invention RU, No. 2382854, C1, IPC E04C 2/00, published on February 27, 2010)

Known, adopted as a prototype, heat and sound insulating honeycomb sandwich panel, comprising two identical surface layers, on the inner sides of which hexagonal recesses are symmetrically made with the formation of bases inside the layers, and the execution between the layers along the perimeter of adjacent spike and groove, diagonally offset from the outside layer surfaces. (Utility Model Patent RU, No. 131756, published August 27, 2013, IPC E04B 1/74)

A disadvantage of the known devices is the low operational reliability and high cost due to the heterogeneity of the materials and adhesives used and the complexity of the design.

The technical result, which is oriented to the proposed device, is to increase operational reliability, while maintaining heat and sound insulation properties, and reduce costs.

The technical result is achieved by the fact that in the heat and sound insulating panel, including surface mirror-made layers, with the formation between them along the perimeter of adjacent spike and groove, offset diagonally relative to the outer surfaces of the layers, and symmetrically made honeycomb cells in the form of regular hexagonal recesses on the inner surfaces of the layers, new is the fact that the spike and groove are formed by mirror-shaped parts on the inner surfaces of the layers in the form of ledges, monolithic with the surface layers. In some cases, the use of single panels is possible.

In FIG. 1 shows the panel in disassembled state, in FIG. 2 is an assembled side view of FIG. 3 is a plan view of FIG. 4 and 5 - execution for special cases.

Here: 1 - surface layers, 2 - inner surface, 3 - hexagonal recesses, 4 - outer surface, 5 and 6 - groove and tenon, 7 - plane of connection of internal surfaces.

The panel is made of known materials, for example: foam, such as polystyrene foam, polyethylene foam, polyurethane foam (PUR), preferably dicyclopentadiene (DCPD) or polyisocyanurate foam (PIR), polypropylene, polycarbonate, ABS plastic, polybutylene terephthalate, polyamide, foam gas foam , or from composites. The manufacturing process is carried out by pouring dosing machines into special forms, or by foaming into closed forms, possibly using vacuum, in a batch manner. If necessary, the front surface layer facing outward may be lined with a decorative coating that will perform the function of protection against environmental influences (including ultraviolet radiation) and is made in the form of:

- protective or tempered glass with a mirror, color coating,

- a metal surface with or without texture,

- clinker tiles,

- porcelain tile

- siding, metal siding,

- plastic

- PVC films

- high pressure laminate (HPL),

- photovoltaic modules.

The opposite surface layer (Fig. 1-3) may have a similar coating, or foil, propylene, vapor barrier film. The layers are bonded by gluing.

Thus, the proposed panel device involves reliable adhesion of the layers to be glued and the formation of a spike-groove lock around the entire perimeter, for connecting the panels to each other.

Installation of panels is carried out in any known manner.

High thermal insulation properties of the proposed panel are provided due to the small vertical gradient of the circulating air flow inside the formed cavities. Sound insulation is ensured by multiple phase transitions and damping of acoustic waves between the filler and the air microspheres of the foamed polymer, as well as high scattering power and sound absorption of the inner surfaces of the cells. The implementation of the layers (Fig. 1-3) and the adhesive composition of a homogeneous material increases the operational reliability and service life of the panels by eliminating interlayer stresses ("shear" deformation forces) under the influence of the difference in the linear coefficients of thermal expansion. The use of mirror panels of homogeneous materials simplifies production technology and reduces the cost of the device while maintaining heat and sound insulation and strength characteristics.

In conditions of lower requirements for the parameters of thermal and sound insulation, single panels are used, glued with an overlap, with the inside on the surface to be protected (Fig. 4-5). If technologically necessary, the panels can be pre-sealed from the inside with any sheet material, for example, moisture-proof drywall.
