Description

The invention relates to the field of industrial and civil engineering, and in particular to structures for heat-insulating cladding of hinged ventilated facades (hereinafter NVF) of buildings and structures, and can be used for fastening ceramic granite cladding panels.

Known are the attachment points of the facing panels to the hinged ventilated facade (clamps) made of a stamped base with molded L-shaped grips corresponding to the thickness of the fixed panel (see, for example, RU 2334061 C2, publ. September 20, 2008). When installing the facade, the clamp is rigidly fixed on the vertical or horizontal profiles of the NVF system. In this case, the panels are covered by a clamp with three sides - they are pressed against the front surface of the clammer with the back side, rest on the horizontal part of the L-shaped petals with the end plane, and are fixed with the vertical part of the L-shaped petals from the front surface.

The disadvantage of this solution is the inability to replace the panel (plate) in case of repair of the lining.

A known retainer for attaching tiles to the facade of the building, made in the form of a plate containing a central part with a hole in its center for a fastener and four cross-shaped petals (RU 108470 U1, publ. 09/20/2011). The latch is installed at the junction of the corners of the four cladding plates so that the fastener installed in the hole (for example, a rivet) connects the latch to the wall, and each lobe presses two cladding plates simultaneously. When repairing the cladding, it is enough to remove two adjacent clamps and remove the plate from under the other two clamps.

A disadvantage of the known latch is that it does not keep the plate from shifting down, does not ensure guaranteed gaps between the plates and does not protect the plate from being pinched when fixing the latch.

The technical problem solved by the proposed device is the creation of a fastening unit for facing panels to a hinged ventilated facade, providing an increase in the degree of reliability of fastening of facing panels with visible fastening when installing ventilated facades.

The technical result, which allows to solve this problem, is to increase the reliability of fastening of cladding plates while ensuring a guaranteed gap between the plates and the profiles of illegal armed groups, as well as between the plates themselves.

The technical result is achieved by a device for mounting hinged cladding plates on the facade of the building, containing a clamping element with a hole in the central part and with petals, which according to the invention has tabs located between the petals and directed in one direction relative to the clamping element.

In the particular case, the clamping element can be made flat.

In another particular case, the clamping element can be made convex in the central part away from the legs.

At the same time, at least one annular corrugation, a concentric hole, can be made on the convex part of the clamping element.

In addition, the device may have two petals and two tabs located diametrically opposite to each other.

In addition, the device can have three petals and three legs, two of which are located with an angular offset of 90 degrees around the circumference centered at the center of the hole, and the third foot is located at the same distance from the first two legs.

In addition, the device may have four cross-shaped petals and four tabs between them.

In addition, the device may have four cross-shaped petals and two legs located diametrically opposite to each other.

In a preferred embodiment, the petals are made expanding in the direction away from the center of the pressing member.

It is also preferable that each petal has a deflection with a bulge in the direction of placement of the legs.

In the particular case, each foot can be made in the form of a plate connected to the clamping element along a line perpendicular to the radius of the circle centered in the center of the hole.

It is possible to implement the device when each foot is rotated around its longitudinal axis by an acute angle.

The proposed device fixes the slab in contact only with the front and end surfaces of the slab, and a system of vertical or horizontal profiles of a hinged ventilated facade (NVF) is used as a support for the slab from the inside.

The proposed device is illustrated by drawings.

A device for attaching hinged cladding plates, preferably of ceramic granite, to the ventilated facade of the building, in one embodiment, is structurally made in the form of a stamped pressing element 1 with four cross-shaped petals 2 (Fig. 1-3) for pressing ceramic granite to the profiles of illegal armed groups. Between the petals 2 there are thrust tabs 3 directed to one side of the pressing element 1 and designed to position the porcelain tiles relative to each other and create a gap corresponding to the thickness of the granite between the pressing petals 2 and the plane of the profiles.

The clamping element 1 is made convex in the central part, the convexity being directed away from the stop legs 3. In the center of the pressing element there is an opening 4, and one or more annular corrugations 5 are made concentrically in the central part of the pressing element 5. The presence of convexity and corrugations increase the rigidity clamping element. But a possible embodiment of the clamping element flat (Fig. 8, 9).

The petals 2 are preferably made expandable in the direction away from the center of the pressing element 1. It is also possible to make the petals without expansion. Each petal 2 is slightly bent towards the placement of the legs 3 and has a deflection with a bulge in the same direction for elastic pressing of the plates.

Each tab 3 is preferably bent away from the clamping element and made in the form of a plate connected to the clamping element 1 along a line perpendicular to the radius of the circle centered at the center of the hole 4. In the particular case, the tabs can be turned around their longitudinal axis by an acute angle (Fig. 6 , 7). This provides a reduction in the stiffness of the contact of the stop legs 3 with the plates. With temperature deformations of the plate profiles, the tabs 3 are simply turned, so that the plates do not break. Devices with straight legs can also be used (Figs. 1-5, 8, 9).

The device with four legs 3 is designed to be placed at the junction of the corners of the four facing plates (Fig. 11). The proposed device can be used to press the plates when placing it on the edge of the cladding at the junction of the corners, for example, three plates, as well as when placing it between two plates. In the first case, the device is performed with three petals 2 and three tabs 3 (Fig. 4), in the second case, with four or two petals 2 and with two tabs 3 (Fig. 5, 8, 9). In the first case (Fig. 4), two legs 3 are located with an angular offset of 90 degrees around the center of the center of the hole 4, and the third foot is at the same distance from both first legs 3. In the second case, two legs 3 (Fig. 5, 8, 9) are diametrically opposed to the center of the hole 4.

Fastening of facing plates using the proposed device (clamp) on the example of a device with four petals 2 and four tabs 3 is as follows.

Klyammer placed at the junction of the corners of the four plates 6 of porcelain. Each petal 2 rests on the corresponding plate 6, and the tabs 3 are placed in the gaps between the plates 6, thereby ensuring the presence of a guaranteed gap between the plates 6.

The petals 2 are molded with a deflection toward the front surface of the granite to ensure elastic fixation of the plate 6, and the thrust tabs 3 prevent the possibility of rigid fixation and clamping of the plate. In addition, the presence of legs 3 eliminates the possibility of slipping plates down.

In the hole 4 in the center of the clamp, a rivet 7 is installed, with the help of which the clamp is fastened to the 8 NVF profiles.

This solution allows, if necessary, to dismantle and selectively replace any cladding plate without violating the position and integrity of the remaining plates.
