EFFECT: energy resource saving, higher efficiency of external barriers Design of a construction external barrier of high thermal resistance includes a bearing hollow panel.
The invention relates to the field of construction, namely the construction fencing buildings structures for various purposes, and can be used as wall and other barriers to residential, public and industrial buildings with the benefit of energy savings in heating and ecology.
You know the invention according to patent WO 03/044293 A1 (applicants: SAINT GOBAIN ISOVER [FR]; ROYAR JUERGEN [DE], IPC E04B 1/62, 1/76, 1/82, 2/74, published. 30.05.2003), in which the wall element consists of two outer casings forming an air space filled with insulating layers, directed parallel to the outer casing, and having a porous, cellular structure of high density.
The disadvantages of this design are clunky, fragility, moisture insulation material due to the lack of a vapor layer, leading to the fall of the heat-shielding properties during operation, sliianie porous insulating material.
The closest in technical essence and the achieved result to the claimed design is a device for additional insulation of the external walls of the premises maintained buildings on the patent of Russian Federation №2172805 (authors: Urmanov B.N., Ivanova Y., Urmanov D.B, IPC E04B 1/76, published. 27.08.2001), including an air layer formed outer wall, perpendicu the RNO installed to her sides and located parallel to the wall facing, covered with aluminum foil, filled with frame made from a sheet of aluminum foil. This design insulation can significantly reduce in the air gap convection and almost completely eliminate the transmission of radiant heat through, which is very efficient and does not require costly materials.
The disadvantage of this design is the low thermal resistance of the layer of heat-insulating panel, the impossibility of increasing the thickness of the layer panel to enhance thermal properties due to the increased convection inside the layers panel.
The main task, the solution of which the invention is directed, is the energy, improving the efficiency of external walls of buildings by reducing material costs in the manufacture of fencing while enhancing thermal properties of exterior walls, ceilings, etc. in the result solves the problem of efficient use of the high thermal resistance of the stationary layer of air at the same time which is the cheapest material. Solved the problem of efficient energy saving in heating and ecology.
This technical result is achieved by the fact that the design and construction of the outer fence of high thermal resistance, the carrier includes a hollow panel, in the morning panel space lined with foil and filled horizontally along the fence in several rows across the width of the panel, the hollow tubes of the foil with a diameter of 30 mm, or hollow channels of the foil with dimensions 30×30 mm, and the number of rows of tubes is not limited and is determined by the required thermal resistance of the outer fence.
Design and construction of the outer fence of the increased thermal resistance consists of a carrier 1, the inner space of which is lined with foil 2 and filled horizontally along the fence in several rows across the width of the panel, the hollow tubes of the foil 3 with a diameter of 30 mm, or hollow channels of the foil, size 30x30 mm, and the number of rows of tubes of ilikeyou not limited and determined the necessary requirements for thermal resistance of the outer fence.
This construction fencing allows you to avoid getting moisture inside, and, consequently, thermal resistance of the fence can be increased several times in comparison with the normative.
It is known that modern construction external enclosures do not allow a tremendous increase in thermal resistance due to the accumulation of moisture within the structure. It is also known that the foil has not only luciocephalus properties, but also vapor-proof. We offer design and construction of outdoor fencing allows so to reduce heat loss in the room is, the use of electricity for heating will be economically viable.
The invention is illustrated by drawings, where figure 1 shows a General view of the construction of the outer fence of the increased thermal resistance.
Design and construction of the outer fence of the increased thermal resistance is as follows. In the carrier 1, the inner space of which is lined with foil 2, horizontally stacked along the fence in several rows across the width of the panel, the hollow tube of the foil 3 with a diameter of 30 mm, or hollow channels of the foil with dimensions 30×30 mm and the number of rows of tubes or channels is not limited and is determined by the required thermal resistance of the outer fence.
This design is in the form of a wall or in separate blocks of different sizes and configurations. In addition, with some structural changes to the unit can be used for floors, coatings, etc. outdoor enclosures. The optimal size of the interlayer thickness of the frame is determined by us based on experimental data 30 mm, which corresponds to a thermal resistance Rto≈1 m2·°C/Watt. Thus, the required thermal resistance of the fence can be obtained by increasing the number number is in the tube diameter of 30 mm, or channels with dimensions 30×30 mm, an Advantage of such a fence is a little thick when required by modern building codes for insulation of external walls and other barriers.
The technical result of the construction of the outer fence of the increased thermal resistance is that during operation it is not moistened due to the lack of propreitary, and its thermal properties remain constant. The total thermal resistance, therefore, can be increased several times compared to normal today. This means that the cost of heat for heating can be reduced to a minimum, which is especially important for rural development.
Design and construction of the outer fence of the increased thermal resistance, including hollow bearing panel, characterized in that the inner space of the panel lined with foil and filled horizontally along the fence in several rows across the width of the panel, the hollow tubes of the foil with a diameter of 30 mm, or hollow channels of the foil with dimensions of 30×30 mm, and the number of rows of tubes or channels is not limited and is determined by the required thermal resistance of the outer fence.
