Description

(54) MULTILAYER THERMAL SOUND-INSULATING - PROTECTION

These contribute to the intensive transfer of thermal and sound energy through the fence. These links, used to create the necessary strength and spatial rigidity of the fence, require increased consumption of insulating material, as well as an unjustified increase in the thickness of the fence and, consequently, its weight.

The purpose of the invention is the improvement of heat dissipation properties of the limitation.

This goal is achieved by the fact that, in a multilayer heat and sound insulation enclosure, including outer layers, connections and an intermediate layer, the connections are made of permanent magnets placed with a gap relative to each other and connected to the inner surfaces of the outer layers by an elastic gasket, and to each other, the sides of adjacent elements, fixed on opposite outer layers, have poles of the same name, and in the gaps there are force fields, the vectors of which are directed in opposite directions, except In addition, the magnets are mounted on opposite outer layers coaxially, made of the same length and placed with a gap, and electromagnets or electrostatic plates and outer layers are covered with protective shielding force fields as magnets.

FIG. 1 is a cross-sectional view of the fence with attached sources of field dispersed; in fig. 2 - the same, with grouped sources of fields; Fig 3 - the same, with symmetrically located nn1 sources of zeros; in fig. 4 - the same, with flat distributed sources of fields. - -JJ

In these figures, the vectors A, Ar, AJ, ... denote the power loads acting on the construction of the enclosure, and the vectors B, Bj, BZ, ... denote the force vectors of the force npjiefl magnets corresponding to the load. Zakami "+ and" - marked the poles of sources of force fields, for example, magnetic or electrostatic.

The heat and sound insulation enclosure contains outer layers 1 and 2 and an intermediate layer 45 formed from magnets 3, interconnected with a gap 4.

As magnets, generators of force fields can be used rassre; Point sources of power zeros, for example, in the form of corrugated or flat, rigid or elastic magnetic tapes. It is most advisable to perform (for example, temporarily) evacuation between the inner layers 55 (for example, up to 10 - 10 mm Hg or less).

Magnets (force field generators) can be made of various shapes, for example, U-shaped with shelves 5 and fixed on the layer by means of elastic gaskets 6.

In addition to rigid plates or panels, for example, films or fabrics of known magnetic materials or nonmagnetic materials that are clad or impregnated with magnetic plastics, magnetoelastics, etc. can be used as layers.

When using transparent magnetic materials, this proposal can be used for heat and sound insulation of light openings and other translucent walling structures.

The outer layers 1 or 2 can be made of a material that shields the force fields, for example, from a soft magnetic metal foil or magnetoplast.

When this type of fence is constructed, rigid mechanical connections between the layers are eliminated, thereby eliminating acoustic-thermal bridges that reduce the heat and sound insulation, which conduct heat and sound currents, and an intermediate insulating layer made of magnets forms contactless power connections between external layers of fencing. When changing (for example, decreasing) of the gap 4 under the action of power loads A ,, Ai, Aj, ... between the magnetic poles of the same magnitude, magnetic repulsive forces B |, B, Bc, ... appear, which balance the applied power loads and support the working gap 4 between the magnets 3 and, consequently, between the outer layers 2. In addition, the contactless power connections in the proposed fence have a highly sharply elastic characteristic. Depending on the change in the gap between the magnets, the bond stiffness (by the very nature of the magnetic coupling) varies according to a power law, bla-. in the barrier, the effect of damping vibrations is enhanced.

The use of a fence with an intermediate layer in the form of magnets favorably distinguishes the fence both from the prototype and from other known solutions, due to the increased heat and sound insulation properties of the fence and a sharp decrease in the consumption of heat and sound insulating materials. When creating such a fence, it is possible to increase the thermal and acoustic characteristics of the fence several times in comparison with the most effective known solutions.
