Description

The invention relates to thermal insulation, in particular to fractured surfaces. The invention is particularly applicable to thermal insulation of pipes of all diameters, for example steam and hot water pipes.

Until now, the thermal insulation of the composite surfaces has been carried out without the use of special products by direct application of the thermal insulation material with sufficient flexibility, often in several layers directly to the insulated place. Mostly, mineral or glass wool fiber mats are used, which are protected against puncture by a cover made of a material of sufficient strength, such as paper, aluminum foil or fiberglass. The disadvantage of such thermal insulation is the fact that Productivity of work · The above-mentioned disadvantages are partially eliminated by thermal insulation made of finished rings. Another disadvantage is the relatively costly transportation costs. These disadvantages are partially eliminated by the thermal insulation formed from the insulating collapsible elements. These collapsible elements are formed from cuboid blanks, for example fiber boards, which are attached to a flexible backing. When the insulation thus formed is applied to the fractured surfaces, gaps are produced between the cross-sections, the dimensions of which increase with the thickness of the insulation layer. This shortcoming can be removed by applying multiple layers on top of each other. The disadvantage of this insulation is that each of the layers needs to be individually fastened with tightening straps, which increases the laboriousness of the insulation assembly and the manufacturing costs. Steel test strips also impair the insulation performance. Manufacturing costs and assembly effort are reduced if the insulation is formed from two layers of insulating, twistable elements, the blanks facing each other so that the blanks of one layer fit into the gaps between the blanks of the previous layer. This disadvantage is also overcome by isolation, which consists of blanks of suitable shape and size attached to the support. However, this insulation cannot be applied to every shape and size of the object to be isolated.

A further reduction in the laboriousness of the insulation installation results in thermal insulation, especially of the fractured surfaces according to the invention. This insulation consists of blanks of thermally insulating material, joined together at one end in a bonding layer. SUMMARY OF THE INVENTION The present invention is characterized in that these blanks are formed curved with a curvature in the form of a continuous curve in a portion between local extremes with a pitch less than 90 ° and greater than 10 °. Another advantage is that the blanks are formed from a shape memory material.

The advantage of the thermal insulation according to the invention is its low assembly effort. This thermal insulation can be applied in a single layer in virtually all desired insulation thicknesses. Also the production of this thermal insulation is simple and unchangeable with respect to the shape and dimensions of the isolated object. The use of blanks of material 8 through face memory allows, by ensuring the shape of the blanks, to ensure and guarantee the thermal insulation properties of this insulation to a relatively narrow extent.

The invention is described in greater detail below by way of example with reference to the drawing, which shows a partial sectional view of the insulation of a hot water pipe.

3yl is made of foam block whose first dimension is equal to the circumference of the hot water pipeline, the second dimension is equal to the thickness of insulation increased by its square power and pipe diameter »In this block at 20 mm in the direction of the second dimension Depth 5/6 of the second dimension, straight cuts to form cuts 1. The rectangular block thus treated was laid from the hot water pipe 6 by an uncut wall forming the connecting layer 2. Then, these blanks were bent and pressed against adjacent blanks χ and their position was determined by two tightening steel strips.

The sheet material 1, which retains the shape memory, was formed into blanks 1, which were joined at the bottom in a bonding layer 2 at a thickness of 1/50 of the blank. These blanks were shaped in the form of a continuous geometric curve with increasing curvature so that the tangent plane 6 to the blank 1 at its free end forms an angle of 70 ° to the bonding layer 6 and the tangent plane 6 to the blank forms this tangent plane. 90 ° to the connecting layer. One strip of steel strip is fully sufficient to secure the position.

The asbestos fabric blanks 1 were bonded to a bonding layer 2 also made of asbestos fabric. The insulation formed in this way was placed on the piping of the second hot water pipe and was then wrapped with two steel strips. Due to the elasticity of the material, the blanks X are curved so that the tangent plane 8 to the blank forms an angle of 87 ° with the tangent plane f to the joint layer and the tangent plane 4 to the blank at its free end forms an angle of 14 ° with the tangential plane.
