Heat-insulated building member

FIELD: building members, particularly heat-insulated building unit used as filler structures, facings and building structures.

SUBSTANCE: heat-insulated building member comprises outer layers, metal foil screen layers, cellular packing layers made of bent paper strips and adhered one to another. Cells of one packing layer are displaced with respect to that of another packing layer. Outer layers are made of metal foil and are used as screens and load-bearing layers. Cellular packing layers are connected with each other by means of flat paper sheets. Planes of adjacent packing layer connection areas are turned one relative another through angle equal or less than 90°. Packing layer thickness, namely cell height, and cell dimensions are reduced towards outer layers. Flat paper sheet thickness increases towards outer layers. Packing layer cells adjoining outer load-bearing layer facing heat-dissipation surface are filled with foaming composition. The foaming composition includes components, which sublimate under the action of high temperature with water vapor or carbonic oxide gas emission. Adjacent packing layers adjoining opposite outer load-bearing layers are filled with ecologically-safe cotton wool. Ratio between flat paper sheets and packing layer thickness (cell height) is 1:1 - 1:250. Ratio between cell height and cell face dimensions is 1:2-1:5. Ratio between bent paper strip thickness used for cell production and packing layer thickness (cell height) is 1:50-1:300. Ratio between mean packing layer thickness (mean 9-th cell height) and heat-insulation layer thickness is 1:2-1:60.

EFFECT: increased load-bearing capacity, strength and fire-resistance along with retention of good heat-insulation properties.

The invention relates to the field of construction, in particular the layered thermal insulation products used in walling, cladding of buildings and structures.

Known insulating element includes outer layers, at least one shielding layer is made in the form of metallized film, at least one intermediate layer having a honeycomb structure and is made of material polyurethane foam [see A.S. USSR №613044, E 04 1/78, publ. 1976]. This insulating element does not have sufficient thermal insulation due to convection in the air strips in the cells of the cushioning layer.

Known insulating element [see Russia's bid No. 2002134092, E 04 2/36, publ. 10.08.2004,] including external hard layers at least one inner layer of paper impregnated with resin, having a cellular structure and additionally filled volumetric filler in the form of foam or basalt, or combinations thereof, as well as an extra layer of basalt or components located between the outer layer and a layer with a honeycomb structure.

The disadvantage of this heat-insulating element is insufficient thermal insulating ability, and the presence in its composition of environmentally harmful materials.

Nibblebit.com known analogues of the proposed technical solution is heat-insulating construction element, includes outer layers, the shielding layers of metal foil, sealing layers of paper, with a honeycomb structure made of curved strips, and screening layers connected with cushioning layers by using adhesive bonding, and the cells of one of the cushioning layer are offset from the cells of another layer (see Patent of Russia №2101428, "Building insulation element, E 043 1/78, E 04 2/36, 32 3/12, publ. 10.01.98].

The disadvantage of this technical solution is that the insulating element has no along with high insulating capacity necessary strength and bearing capacity, and it is characterized by reduced resistance due to the presence in the outer layers of paper.

The technical result of the proposed solution is to increase the bearing capacity, durability and fire resistance while maintaining a high thermal insulation capacity.

This technical result is achieved by the heat-insulating construction element, comprising outer layers, the shielding layers of metal foil, sealing layers with a honeycomb structure made of bent strips of paper, and interconnected with glue, and the cells of one of the cushioning layer are offset from the cells of another cushioning layer has about the differences, namely, the outer layers are made of metal foil and function shielding and structural layers, spacer layers with a honeycomb structure are interconnected using a paper flat sheets, and the plane of the gluing curved strips in the adjacent gasket layers are rotated one relative to the other at an angle less than or equal to 90°, the thickness of the cushioning layer (the height of the cells) and the cell sizes in the cushioning layer is variable and decreases towards the outer layers, the thickness of the flat paper sheets made increasing towards the outer layers of the cell cushioning layer adjacent to the outer bearing layer facing to heat the plane, filled with the composition containing components, subliminale under the influence of high temperature water vapor or carbon dioxide, and adjacent and contiguous to the opposite outer bearing layer cushioning layers filled with cellulose wool, and the ratio of the thickness of the flat paper sheets to the thickness of the cushioning layer (the height of the cells) is 1:5-1:250, the ratio of cell height to the dimensions of the faces of the cells is 1:1-1:5, the ratio of the thickness of the curved paper tapes are made of cells, the thickness of the cushioning layer (the height of the cells) is 1:50-1:300 the average thickness of the cushioning layer (average high is and cells) to the thickness of the insulating element is 1:2-1:60.

In addition, insulating construction element may contain at least one additional shielding layer located between the cushioning layer having a honeycomb structure.

In addition, the face side insulating construction element further bonded straps.

In addition, straps are made of self-adhesive.

In addition, insulating construction element according to the perimeter provided with a frame at the height of the insulating construction element.

The execution of the thickness of the cushioning layer (cell height) reduces to the external layer, combined with the increasing thickness of the flat paper sheets significantly increases structural strength and load bearing capacity of the heat-insulating construction element.

The rotation planes gluing paper strips in the adjacent gasket layers relative to each other increases the strength of the element as a whole.

The presence of adhesive tape covering the face side insulating construction element, allow increasing its strength and bearing capacity.

The performance of insulating construction element with an outer layer of metal foil, performing load-bearing and shielding function, combined with the fact that about ladochy layer, adjacent to the heat of a plane filled with foaming composition containing components, subliminale under the influence of high temperature water vapor or carbon dioxide can significantly improve the resistance of the insulating construction element, as well as to reduce heat transfer due to reflection of radiation by the metal layers.

The presence of additional internal shielding layers enhances the insulating properties of the cushioning layer.

To increase the bearing capacity and to improve the ease of installation of perimeter insulation of a building element is equipped with a frame.

The best ratio of heat-insulating properties to the strength and bearing capacity is achieved when the ratio of the thickness of the flat paper sheets to the thickness of the cushioning layer (the height of the cells)of 1:5-1:250, the ratio of cell height to the dimensions of the faces of the cells is 1:1-1:5, the ratio of the thickness of the curved paper tapes are made of cells, the thickness of the cushioning layer (the height of the cells), equal to 1:50-1:300, the ratio of the average thickness of the cushioning layer (the average height of the cell) to the thickness of the insulating element, which is 1:2-1:60.

The plane gluing curved tape 3 (see figure 2) in the adjacent gasket layers 2 are rotated one with respect to another on the corner ≤90°. The thickness of the cushioning layer 2 (the height of the cells H) AC and decreases towards the outer layers 1. Cushioning layers 2 are connected using a paper flat sheets 4, the thickness of which increases towards the outer layers 1.
