Comparison of the claimed technical solution with the prior art known from the scientific, technical and patent documentation as of the priority date, in the main and adjacent headings, did not reveal a means that has features identical to all features contained in the claims proposed by the applicant, including the characteristics of the purpose.

Consequently, the set of essential features of the claimed solution was not previously known and is not identical to any known technical solutions, therefore, it meets the "novelty" condition of patentability.

This technical solution is industrially applicable, since its purpose is indicated in the description of the application and the title of the invention, it can be manufactured industrially and used for the construction of heat-insulating walls of buildings and structures.

The technical solution is efficient, feasible and reproducible, and the distinctive features of the device allow you to obtain a given technical result, i.e. are essential.

The invention in the form as it is characterized in the claims can be carried out using the means and methods described in the prototype - patent US10487501, which became public before the priority date of the invention.

Therefore, the claimed technical solution meets the "industrial applicability" requirement of patentability.

The analysis of known technical solutions in this field of technology showed that the proposed technical solution does not follow explicitly from the prior art for a specialist, since no solutions have been identified that have features that coincide with its distinctive features, and in the identified such solutions, the knowledge of the influence of distinctive features on the technical result specified in the application materials.

That is, the claimed solution has features that are absent in the known technical solutions, and the use of these features in the claimed set of essential features makes it possible to obtain a new technical result - to simplify the design and improve the heat-shielding qualities of the walls.

Consequently, the proposed technical solution can only be obtained by a creative approach and is not obvious to the average specialist in this field, i.e. has an inventive step in comparison with the state of the art.

The implementation of the claimed invention is achieved by the implementation of the specified purpose.

Permanent formwork blocks consist of two non-metallic panels connected by polypropylene ties. The block is assembled directly at the construction site.

The internal space between the panels is reinforced and filled with concrete. The connection means located above, below and from the ends of the block reliably fasten the blocks during the installation of walls and exclude the flow of concrete.

End anchor elements 8 and 9 of both struts 5 and 6 by tightening them with clamps 7 fasten panels 2 and 3.

Plates closing the bases 18, outer plates 21 and extended longitudinal walls 19 of the outer anchor element 9 are placed in the corresponding reciprocal internal recesses in the associated foam panel with a depth according to the ratio S> 1 / 5H, where: S is the depth of the external anchor element penetration into the foam panel, and H is the thickness of the foam panel (Fig. 11).

For the block formed by one foam panel and one gypsum panel (Fig. 9), at one end of each base, an anchor element is made with inner 18 and outer 21 plates, which is fixed in the corresponding panels.

On the upper surface of the flange of the base 7 of the upper strut 5, at least two groups of protrusions 22 are made, spaced from the transverse axis of the I-beam.

All elements of the tie 1 are made of polypropylene. Spacers 5 and 6 are inserted from below and from above into each mating panel and pulled together with clip retainers 11 of panels 2 and 3. The specified comb projection 16 allows for an adjustable connection and can be equipped with a catch 23 for greater strength.

The connection of vertically adjacent blocks is strengthened by the fact that protrusions 22 are made on the upper strut 1, which can be in the form of a cylinder or a cone.

Ties have a fast, reliable fixing system and can be used when joining panels of different thickness, depending on design solutions and heat engineering requirements.

One formwork panel, consisting of foam, is insulating on the outside of the wall, and a moisture-resistant gypsum formwork panel forms a smooth inner wall surface.

The implementation of the invention allows you to minimize the assembly time of the block at the construction site, to simplify the formwork structure, to increase the fire safety and fire resistance of the building, to improve the heat-shielding qualities and to achieve economical indicators by saving materials for interior wall decoration, which ensures the achievement of the claimed technical result
