Description

 The invention relates to the field of industrial and civil engineering and can be used for facing surfaces of industrial, administrative, residential and domestic buildings.

 Known metal tiles fastened to the surface to be coated with fasteners - decorative bolts. See, for example, L.G. Osipov. Civil and industrial buildings, M., Higher School, 1964, p. 462.

 Known panel made of sheet metal for facing facades, roofs and walls, containing the middle part, the curved side edges and a two-element docking lock, the elements of which are placed on the curved side edges of the panel SU 1828482 A3, E 04 F 13/12, 07/15/1993, 5c and which is the closest analogue of the claimed invention.

 The disadvantages of the known panel made of sheet metal are its low performance in terms of creating a ventilated air gap between the panel and the surface to be coated (decay of a wooden crate).

 From the same source (SU 1828482), a docking lock for cladding panels is also known, containing two elements, one of which enters the other when closed.

 A disadvantage of the known docking lock is associated with ensuring the sealing of the connection, which requires the use of auxiliary operations and equipment during the assembly of the structure.

 When developing the proposed designs, the problem was solved of increasing the reliability of the cladding in terms of tightness and improving performance in terms of creating a ventilated air gap under the cladding and eliminating its warping with time from internal stresses.

This problem is solved due to the fact that the facing panel contains a middle part, bent side edges and a two-element docking lock, elements of the docking lock are located on the bent side edges of the panel, an additional support is made in the middle part of the panel in the form of a two-wall rib resting on a symmetrically curved side edges panel the middle part of the panel, and the angle of limb of the side edges is 41 ^o 53 ', while one of the elements of the docking lock is made with the possibility of support on the surface to be coated.

 This problem is also solved by the fact that the docking lock for cladding panels contains two elements, one of which enters the other when closed, the female element is made in the form of a fold, the male element in cross section is made in the form of a sine wave with an amplitude increasing towards the bottom of the fold, measured at an angle to the longitudinal axis of the enclosing element.

The angle of inclination for measuring the amplitude of the sine wave is 41 ^o 53 '.

 The amplitude of the second half-wave of the sine wave is two amplitudes of the first half-wave.

The half-waves in the sine wave are made different in length, while the second does not reach 90 ^o , and the first 180 ^o .

 The analysis of the prior art by the applicant, including the search for information on patent and scientific and technical sources, made it possible to establish that there are no analogues of the claimed devices that are identical to all their essential features.

 Therefore, the claimed cladding panel and docking lock for cladding panels meet the criterion of "novelty" of the current patent law.

 To verify compliance with the requirement of the criterion of "inventive step", the applicant conducted an additional search for technical solutions in order to identify features that match the distinctive ones from the selected prototype.

 Found: the claimed objects do not explicitly follow from the prior art. Therefore, the objects of protection meet the criterion of "inventive step".

 In FIG. 1 is a cross-sectional view of a facing panel.

 In FIG. 2 is a cross-sectional view of a male member of a docking lock.

 In FIG. 3 is a cross-sectional view of a docking lock for facing panels.

The facing panel is made as follows. The profile is made of metal with a multilayer polymer coating or of galvanized steel with a thickness of 0.55 mm, followed by painting with powder enamels of different colors. The panel contains a middle part 1, bent side edges 2, elements 3 and 4 of the docking lock. Elements of the docking lock are placed on the curved side edges 2 of the panel. The element 4 of the docking lock is made with the possibility of support 5 (main) on the facing surface (not shown in the drawing). An additional support 6 is made on the middle part of the panel in the form of a two-wall rib 7 (the walls are connected until they touch), resting on the middle part of the panel bent symmetrically to the lateral edges. The angles of bending and deflection equal 41 ^o 53 '. Their value is determined together with the choice of the geometric parameters of the elements of the docking lock. The lower point of the double-walled rib and the main support 5 are at the same level, while the length of the support 5 is 2.5 times the length of the element 4 of the docking lock intended for support. Docking lock member 3, as shown in FIG. 3, enters element 4 when two panels are closed. Element 4 (covering) is bent in the form of a fold - an equilateral groove, and the covered element 3 in cross section is made in the form of a sine wave with amplitude increasing toward the bottom of the fold 8, measured at an angle to the longitudinal axis of the covering element (Figs. 2 and 3), this the angle of inclination is ('' alpha ") 41 ^o 53 '.

The amplitude of the second half-cycle of the sine wave is two amplitudes of the first half-period (figure 2). The half-waves of the sine wave 9.10 are made in such a way that the second half-wave does not reach 90 ^o , and the first 180 ^o . As stated earlier, this depends on the angle of bending and deflection of the panel.

 The assembly of the cladding panels is carried out on the pre-transverse transverse crate. The first panel is installed horizontally or vertically and, given its small thickness, is nailed along the edge of the main support 5. It can be perforated, which is not always convenient, because the latter is linked to the crate.

 The next panel is covered by the male element 3 of the docking lock is inserted into the female element 4 of the already fixed panel until it stops, and the second panel is fixed. Due to the elastic properties of the material and the shape of the elements of the docking lock assembly is reliable in terms of tightness. The design of the non-leaking docking lock allows you to mount the panels without folding, i.e. without the use of edge bending machines. Additional support of the panel does not allow the panel to bend at any length (10 m or more). The lightweight facade is mounted regardless of the season, the panels provide an effective air gap and significantly exceed the prototype in terms of performance (service life of more than 35 years).

 Thus, the above information about the claimed invention is characterized in the independent claims, indicate the possibility of their implementation using the described methods and known means and methods. Therefore, the claimed device meets the condition of industrial applicability of the invention.
