Listed distinguishing features are essential, as they are all aimed at solving the problem and achieving a technical result.

The sign of "power" in relation to the construction elements made of composite material, which is the claimed element, means "perceiving mechanical stress (tensile, compression, bending, etc."), as well as internal and external influences (temperature and humidity conditions of the environment, the degree of tightness, erosion effects, and so on). The impact of loads, their type, duration, etc. determine the choice of starting materials, the reinforcing pattern, product structure, etc. and because the design and material of the composite material are created at the same time, the indication of "power" once said about high strength or other specifications isDeleted potreblyaemoi concept of "force" in this sense, in relation to the panels, shells, rods, beams, etc. can be found in the technical literature, in particular, in the directory "Composite materials. Handbook edited VLA. M: mechanical engineering, 1990, ch.4 str, ch.5, str, or in the book Immusano, Ora. Technology missile and aerospace structures made of composite materials. Izd-vo MGTU im. Bauman, Moscow, 1998, str, 457, 463.

Signs "in the form of panels" and "shell" refers to the claimed subject matter in General and characterize variants of the forms of its implementation, which is presented in figure 1-6, in the text of the description and in paragraphs 1-24 claims.

In the above reference, ch.5 on str, on the panel States the following: "the Panels in structural mechanics called thin-walled structures having the form of an open shell with a smooth, generally flat surfaces, the limited contours of different shapes". In another reference: "Panin V.F., Gladkov Y.A. Design with filler: Reference. - M.: mechanical engineering, 1991. - 272 S.: ill." we present on figure 1.1, page 9 some of the options form panels with the following symbols: a, b - flat panels, b - wedge-panel, curved panel. Thus, the flat panel is a common, but not the only structural form panels.

On the other hand you want to add, tobolski divided into cylindrical, conical, spherical, etc., closed and unclosed in the transverse direction, and arbitrary axisymmetric cross-section, thin-walled and thick-walled. One of the species are gentle shell, which are defined as follows: "Flat is the shell, in which the angles of the lines drawn on its surface, so small that within the accuracy of computing the cosines of the angles can be considered equal to the unit". - M.: Higher. School, 1982. - 400 C.". It is seen that design in the form of shallow shells almost close to flat and closed with structures in the form of curved panels. So signs "in the form of a panel, and optionally in the form of a shell together cover a wide range of forms of design from the flat, through the gentle, for example, in the form of canopies, through open arbitrary cross-section, for example, in the form of troughs, trays, etc. to open shells, for example, pipes.

Such features of the inventive heating element is one of the main advantages in comparison with the object, taken as a prototype, which can only be done in the form of a flat panel.

The frame object has the main power loading, isolates the conductive elements are inextricably combines all the layers together its a polymeric binder, but no more.

In the inventive heated power construction element all main components: the frame, the conductive screen and the heater is made of compatible materials and integrated into a coherent whole. The conductive screen TV and electric heater placed between the layers of reinforcing material frame and zamonolichennyj them together with the matrix material with the formation of the composite whole. Accommodation hermetically isolated heater insulating material of the frame element provides stable electrical properties, and the use of low-density layer of material in the frame element provides the necessary rigidity.

The protective properties of the element attached to the cover, the choice of which is determined by the degree of necessary surface protection and compatibility of the coating with the material of the frame.

All of the above ensures the operational reliability of the proposed design heated power construction element.

The construction element according to the invention allows a wide diversity of its forms, from flat and curved panels to closed and open shells. The item is easy to assemble and can be easily replaced in the past life.

In dependent clauses 2-4, 12, and 16 are shown as embodiments of the invention, the materials for the frame, the conductive screen and coatings, and in paragraph 6 - types of structures used for the heater. A more detailed study of these variants are listed in paragraphs 5, 7, 8, 9, 10.

In this case the heating elements can be the same or different sizes and are located at the surface of the construction element and/or its thickness. The number, size and arrangement of the heating elements is determined by the specific requirements on the required capacity of the heating element and the temperature distribution on the surface and the operating time. These heaters can have each own conductive wires that are connected to a separate supply circuits can be combined in several electric groups with serial or parallel connection can have one or zero power wire with a separate power respectively, or zero for each of the heater, and can be combined scheme of the listed according to specific requirements. To formulate separately every possible option is impossible, since they are endless, as the infinite number of possible options dimensions and configurations of the construction element.
