Description

The proposed technical solution relates to the field of construction in terms of sheet cladding, namely, to the method of hidden fastening of cladding plates and a hidden fastener (clamp), which can be used both for exterior and interior decoration of buildings, as well as as part of a hinged facade system for realization of the hidden fastening of the specified plates.

The following concealed fastening systems are known from the prior art.

RF patent No. 2616951 discloses a system for hidden fastening of building cladding slabs, in which a cladding panel is cut on its upper and lower parts, where a bearing element is inserted, which is equipped with at least one L-shaped hook, and a removable element, which is made S-shaped shape and with the possibility of fixing one of its parts in the longitudinal groove on the upper or lower end part of the facing panel, and its other part - on the carrier element hook, wherein the fastening of the removable element in the groove of the facing panel is made rigid, and the fastening on the carrier element hook is sliding.

This system allows quick installation and dismantling of cladding panels, and also allows you to simplify the entire structure due to universal and uniform elements. However, a significant disadvantage is the impossibility of fastening plates with beveled top and bottom edges, as well as the fact that atmospheric water can accumulate in the end cuts of the facing panel, which, when frozen, can cause chipping of the panel edges.

Patent KR 100751487 (application KR 20040093874) discloses a system of concealed fastening of building cladding slabs, in which the concealed fastening clamp is made of two clamps: carrier and clamping clamps, each of which contains a corresponding hook, while both clamps in the assembly are rigidly fixed to each other, and said hooks as an assembly are directed towards each other.

The closest analogue of the proposed invention is a fastener known from the patent of the Russian Federation No. 2713006 dated 03.02.2020. This fastener is made of two clamps: a carrier and a clamping element, in which the carrier clamp is made with one hook and a horizontal shelf, where the specified shelf is installed on the said carrier clamp from the side opposite to the edge with the hook, and a hole is made in the central part of the hook, and the clamp the latch is made with one hook, where on the side opposite the edge with the hook, in the central part, an extension is made, the width of which is less than or equal to the width of the said hole in the bearing latch. At the same time, in the assembly of the clamps, an extension of the clamping clamp enters into the hole of the carrier clamp, and they are rigidly fixed to each other, and the said hooks in the assembly are directed towards each other.

The disadvantages of the well-known design according to the patent of the Russian Federation No. 2713006 is the difficulty of mounting plates or structures fixed by this fastener, due to the fact that when fixing the plates or structures to this fastener, the clamping latch has to be drilled at the installation site, while rigidly fixing the carrier and clamping latch additional tool.

Another disadvantage of the known design according to the patent of the Russian Federation No. 2713006 is the difficulty of leveling the plates or structures fixed by this fastener due to the imperfection of the design of the regulating element for setting the horizon level.

These shortcomings complicate the installation of plates or structures fixed by this fastener.

The technical result is the simplification of the installation of plates or structures fixed by this fastener.

The technical result is achieved by the fact that the fastening element is made in the form of two clamps: bearing and clamping. Where the carrier latch is made with one hook and a horizontal shelf, while the specified shelf is installed on the said carrier latch from the side opposite to the edge with the hook, two transverse holes are also made in the carrier latch, and one in the end central part of the hook. And the clamping latch is made with one hook, where from the side opposite the edge with the hook, in the central part, an extension is made, the width of which is less than or equal to the width of the said end hole in the carrier latch, while in the assembly of the latch, an extension of the clamping latch enters into the hole of the carrier latch and they are made with the possibility of being rigidly fixed to each other, and said hooks as an assembly are directed towards each other. Also, a threaded hole is made in the horizontal shelf, into which an adjusting screw is screwed in, which allows adjusting the level of the horizon of the elements fixed by this fastener. Two transverse holes are made in the clamping latch, and the holes in the bearing latch are made in the form of oblong holes coinciding with the transverse holes of the clamping latch when the fastener is assembled.

Said retainers can be made in the form of a plate, while said at least one hook is made in the form of a bent edge of the plate.

The essence of the claimed technical solution is illustrated by drawings Fig.1-5, where

figure 1 shows a General view of the proposed fastener,

figure 2 shows a General view of the bearing latch,

figure 3 shows a General view of the clamping latch,

figure 4 shows a diagram of the installation of the fastener in the facing plate,

figure 5 shows a General view of the proposed fastener with an adjusting screw.

In figure 1, the positions indicate the following elements.

1 - bearing latch;

2 - clamping latch;

3 - hook of the bearing latch;

4 - clamping latch hook;

5 - horizontal shelf of the carrier latch;

6 - extension of the clamping latch;

7 - end hole in the bearing latch;

8 - a threaded hole made in the horizontal shelf of the carrier latch;

9 - transverse holes of the carrier latch;

10 - transverse holes of the clamping latch.

The implementation of the invention is provided in the following way.

Fastening element for concealed fastening of cladding plates, see figure 1, is made of two retainers: bearing (1) and clamping (2). Typically, the above-mentioned retainers (1 and 2) are made from a plate, in which one edge is bent relative to the plane of the entire plate to obtain the corresponding hook (3 and 4). It is obvious that each of these hooks (3 or 4) can be made in the form of a bend of the entire edge of the plate, and only part of it (not shown), or be made in the form of two bent edges (parts of the edges of the plates) (also not shown in the figures). On FIG. 1, 4 and 5 can be seen

that the specified hooks (3 and 4) of the clamps (1 and 2) when assembling the fastener to install it on the reverse side of the fixed plate are always directed towards each other and, usually, the angle between them is 90°, which allows to achieve optimal performance in terms of holding the corresponding plate.

At the same time, it is obvious that the cuts that are made on the reverse side of the fixed plate (Fig. 4) are made at an angle between them, which is similar to the angle between the indicated hooks (3 and 4), i.e. 90°. It will also be apparent to those skilled in the art that these angles may deviate from the specified optimal value of 90°.

The bearing latch (1) is made with a hole (7) at the hook (3), and the clamping latch (2) on the side opposite the edge with the hook (4) is made with an extension (6).

Obviously, the width of the extension (6) of the latch (2) must be less than or equal to the width of said hole (7) in the bearing latch (1).

Hole (7) and extension (6) allows assembly of the fastener without horizontal shifts or distortions that will not allow the hooks (3 and 4) to align with the corresponding cuts on the reverse side of the plate to be fixed.

Also, in the carrier latch (1), two transverse holes (9) are made, which are made in the form of oblong holes.

And in the clamping latch (2) two transverse holes (10) are made.

In this case, the holes (9) and (10) are made at the same level in the corresponding latches (1) and (2) and in such a way that the holes (9) in the assembly of the latches (1) and (2) correspond to the holes (10), for attaching by means of them the proposed fastener to any flat element, for example, a plate.

The bearing latch (1) on the side opposite the edge with the hook (3) is made with a horizontal shelf (5) in which a threaded hole (8) is made (preferably in the center of the shelf), into which the adjusting screw is screwed, see Fig.5, allows you to adjust the level of the horizon of the elements fixed by this fastener. At the same time, holes are also made in the horizontal shelf (5) for installing fixing fasteners on the corresponding horizontal profile (not shown in the figures), which can be made in the form of a corresponding L-shaped or any other profile having a corresponding vertical bend, on which a horizontal shelf (5) of said fastener is installed. The horizontal shelf (5) is usually made with three holes, where the extreme ones are intended for rigid fixation of the fastener on the profile, and the middle one is a threaded hole 8 for installing a regulating element in the form of a screw into it, which is necessary for horizontal alignment of the element installed on the profile fixed by this fastener, for example, plates.

Also, the bearing retainer (1) can be used without the adjusting screw installed in the threaded hole (8) and used to fasten the wind element.

Hidden fastening of elements attached by the proposed fastener, for example, plates on the corresponding L-shaped or any other profile having a corresponding vertical bend, including a hinged facade system with an air gap, is carried out as follows.

On the reverse side of the fixed plate, cuts are made towards each other (see Fig.4), while the corresponding angle between the cuts is identical to the angle between the hooks (3 and 4) of the clamps (1 and 2).

Next, the proposed fastener is installed in the mentioned cuts in such a way that the hook (3) of the carrier (1) and the hook (4) of the clamping (2) clamps of the said fastener enter into the corresponding said cuts. In this case, when assembling the carrier (1) and clamping (2) fasteners of the mounting bracket on the reverse side of the fixed plate, the extension (6) enters the hole (5). To strengthen the connection of the fastener with the plate, an adhesive or other retaining composition is applied to the said cuts. In addition, the elongated holes (9) of the carrier latch (1) are located opposite the holes (10) of the clamp (2).

Next, a fastener, for example, self-tapping screws, is screwed into the holes (9) (10), thereby fastening the carrier latch (1) with the clamping latch (2) and with the attached plate.

Next, the plate with the corresponding clamps is installed on a horizontal profile, and the panels are adjusted in height. The adjustment is carried out by means of adjusting screws passing through the horizontal profile and entering the threaded holes 8, made in the horizontal shelf of the bearing clamps for setting the horizon level of the panels. After installing the entire row of plates, the end plates are fixed on the horizontal profile through the mentioned end (may not be end) holes made on the shelf (5). Moreover, one of the said extreme holes is usually made in the form, for example, of an ellipse or elongated holes, which will make it possible to compensate for possible temperature deformations.

If it is necessary to install large-sized cladding slabs, it is possible to make two or more rows with cuts on the reverse side of the slab with the installation of the appropriate number of fasteners. And when installing such plates with two or more installed rows of fasteners on its reverse side, only the upper row of fasteners is fixed to the said horizontal profile.

The fastener, made in the claimed manner, greatly simplifies

the process of its manufacture, since a standard strip of metal is used for manufacturing, and all elements of the clamps included in the fastener do not require special operations. Installation of plates with fasteners fixed on it also does not require the use of special tools, easy access if it is necessary to replace a defective or damaged plate, and also allows you to quickly adjust the installed plates along the horizon.
