A device for fixing hinged facing plates on the facade of the building contains a pressing member 1 with an opening 4 and with stop legs 3 that are directed to one side of the pressing member 1. Two legs 3 are located on the opposite sides relative to the opening 4. The pressing member may be circular or with lobes 2, between which the legs 3 are located. The device may have four lobes 2 and four legs 3, or four or two lobes and two diametrically located legs. The pressing member 1 may be flat, but preferably is convex in the central portion and has one or more annular corrugations 5 on the convex portion for greater rigidity. The lobes 2 are preferably formed extending in the direction from the center of the pressing member 2. Each lobe 2 has a deflection with a convexity towards the location of the legs 3. The invention makes it possible to increase the reliability of fastening of facing plates while ensuring a guaranteed gap between plates and HVF profiles, as well as between the plates themselves.

Description

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

Known nodes for attaching cladding panels to a hinged ventilated facade (clamps) made of a stamped base with molded L-shaped grips corresponding to the thickness of the panel to be fixed (see, for example, RU 2334061 C2, publ. 20.09.2008). When constructing the facade, the clamp is rigidly fixed on the vertical or horizontal profiles of the IAF system. In this case, the panels are covered with a cleat from three sides - with the back side they are pressed against the front surface of the cleat, with the end plane rest on the horizontal part of the L-shaped petals, and from the front surface are fixed with the vertical part of the L-shaped petals.

The disadvantage of this solution is the impossibility of replacing the panel (plate) in the event of repair of the cladding.

Known latch for fastening facing slabs to the facade of a building, made in the form of a plate containing a central part with a hole in its center for a fastening element and four crosswise located petals (RU 108470 U1, publ. 09/20/2011). The latch is installed at the junction of the corners of the four facing plates in such a way that a fastening element installed in the hole (for example, a rivet) connects the retainer to the wall, and each petal presses simultaneously two facing plates. When repairing the cladding, it is enough to remove two adjacent clamps and remove the plate from under the other two clamps.

The disadvantage of the known retainer is that it does not keep the plates from shifting downward, does not ensure compliance with the guaranteed gaps between the plates and does not protect the plates from being pinched when fixing the lock.

The closest to the proposed device is a device for fastening facing slabs of facades of buildings, which is a closing element of the clamp, containing a shelf with several mounting holes arranged in a row, two L-shaped presser feet and two adjusting feet directed to one side of the shelf (RU 76939 U1, publ. 10.10.2008).

The known device can be used for placement between two plates and for their fastening only in conjunction with the starting element of the clamp. It alone cannot be used, since the working clamping part of the shelf and all the legs are located on one side of the line connecting the centers of the fastening holes intended for attaching the device to the IAF profile. Therefore, without the use of the second starting element, the locking element, when placed between the plates, is able to press only one plate located on one side of the holes.

The technical problem solved by the proposed device is the creation of a unit for attaching the cladding panels to the hinged ventilated facade, which provides an increase in the degree of reliability of fastening the cladding panels with visible fastening when arranging ventilated facades.

The technical result, allowing to solve the specified problem, consists in providing the possibility of using a device consisting of only one element for fixing the plates when it is placed between the plates at their junction.

The technical result is achieved by a device for fixing hanging cladding plates on the facade of a building, containing a clamping element with a hole and legs directed in one direction relative to the clamping element, characterized in that the hole is located in the central part of the clamping element, while two legs are located on opposite sides with respect to holes.

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

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

In this case, at least one annular corrugation concentric with the opening can be made on the convex part of the pressing element.

The clamping element can be made round, and the legs are connected to its edges.

In addition, the pressing element can be made with petals, between which the legs are located.

In this case, the device can have two legs.

In addition, the device can have three legs located with an angular offset of 90 ° around the circumference centered in the center of the hole.

In addition, the device can have four cruciform legs.

In this case, in one embodiment, it can have four cruciform petals and four legs located between them.

Alternatively, it can have four cross-shaped petals and two legs.

In a preferred embodiment, the petals are made to expand in the direction from the center of the pressing element.

It is also preferred that each petal has a deflection with a bulge towards the location of the legs.

In a particular case, each tab can be made in the form of a plate connected to the pressing 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 tab is rotated around its longitudinal axis at an acute angle.

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

A device for attaching hinged facing slabs, preferably made of ceramic granite, on a ventilated facade of a building, in one embodiment, is structurally made in the form of a stamped clamping element 1 with four cruciform petals 2 (Figs. 1-3) for pressing the porcelain stoneware to the IAF profiles. Between the petals 2, stop lugs 3 are made, directed to one side of the clamping element 1 and intended for positioning the porcelain stoneware slabs relative to each other and creating a gap corresponding to the thickness of the porcelain stoneware between the clamping petals 2 and the plane of the profiles.

The clamping element 1 is made convex in the central part, while the bulge is directed away from the thrust legs 3. In the center of the clamping element there is a hole 4, and one or more annular corrugations 5 are made concentrically to it in the central part of the clamping element 5. The presence of the bulge and corrugation increases the rigidity clamping element. But it is possible to make the pressing element flat (Fig. 8, 9).

The petals 2 are preferably made expanding in the direction 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 location 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 is made in the form of a plate connected to the clamping element 1 along a line perpendicular to the radius of the circle centered in the center of the hole 4. In the particular case, the legs can be turned around their longitudinal axis at an acute angle (Fig. 6 , 7). This provides a decrease in the rigidity of the contact of the stop lugs 3 with the plates. In case of thermal deformations of the slab profiles, the legs 3 are simply turned, thus, the slabs will not collapse. Straight leg devices can also be used (FIGS. 1-5, 8, 9).

It is possible to implement the device without petals 2, while the legs 3 are located along the edge of the clamping element 1 (Fig. 10-15). The pressing element can have any suitable shape, in particular round. In this case, the pressing element 1 can also be made either flat (Fig. 8-11) or convex (Fig. 12, 13), it can also have at least one corrugation 5 (Fig. 14, 15). The device can also have four, or three, or two legs 3, as in the presence of petals.

The device with four legs 3 is designed to be placed in the place of joining the corners of four facing plates (Fig. 16, 18). The proposed device can also be used for pressing plates when placing it between two plates. In this case, the device runs with four or

- 2 038922 with two petals 2 and with two legs 3 (Figs. 5, 8, 9). Two legs 3 are located diametrically opposite to the center of the hole 4. It is also possible to make the device with three legs 3 located at an angular offset of 90 ° relative to each other (Fig. 4).

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

The clamp is placed at the junction of the corners of the four slabs 6 of porcelain stoneware (Fig. 16-18). Each petal 2 abuts against the corresponding plate 6, and the legs 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 bend towards the front surface of the porcelain stoneware to ensure elastic fixation of the slab 6, and the stop lugs 3 prevent the possibility of rigid fixation and pinching of the slab. In addition, the presence of the legs 3 excludes the possibility of the slabs slipping down.

In a device made without petals, the edges of the clamping element 1 are pressed against the plates.

A rivet 7 is installed in the hole 4 in the center of the cleat, with which the cleat is attached to the profiles 8 of the NVF.

The use of the proposed device provides a guaranteed gap between the slabs and profiles of the IAF, as well as between the slabs themselves.

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