Description

The group of inventions relates to the field of industrial and civil engineering, namely, to structures for heat-insulating cladding of hinged ventilated facades (NVF) of buildings and structures, and can be used for fixing facing panels made of ceramic granite or natural stone.

Known mount the facing elements to the hinged ventilated facade (EP 0725874 B1, publ. 02.28.2001). The fastening elements of this technical solution are rigidly attached to the vertical or horizontal guides of the hinged ventilated facade, after which the ceramic granite panel is put on the upper element with the lower cut, and the lower element is inserted into the upper cut, which is then rigidly attached to the guide profiles.

The disadvantage of this solution is the high percentage of marriage of facing panels during installation, as well as the low reliability of fastening panels. As a result, the thickness of the plate (panel) at the place where the paws are gripped does not exceed 5 mm. The material of ceramic granite slabs is quite fragile. To ensure a uniform gap between the panels on the facade, they must be moved and adjusted in place during installation. Since the elements included in the cuts are previously rigidly connected to the guides, this leads to a large amount of chipping of the edges of the panels. In addition, the vibrational and temperature deformations of the IWF guides through the fastening elements rigidly fixed on them are also transmitted to the panel cut zone, causing chipping of the edges.

Closest to the proposed one is a device for mounting hinged facing panels made of ceramic granite on the facades of buildings in a hidden way (RU 2403355 C2, publ. 10.11.2010), which includes upper and lower fasteners (grips), while the upper element is made with the possibility of placement in the longitudinal cut on the upper end part of the cladding panel, and the lower element is made with the possibility of placement in the longitudinal cut on the lower end part of the cladding panel. The lower and upper elements are rigidly interconnected by a vertical bar with the formation of a modular fastening element. The vertical bar in the upper part is equipped with a bracket for fastening to the guide of the hinged ventilated facade, and in the lower part is equipped with a fastening element made with the possibility of sliding engagement with the bracket of the downstream panel.

The disadvantage of this solution is the difficulty of making cuts in the end of the ceramic plates, as well as breaking off the thin parts of the plates formed by the slot, which leads to increased consumption of cladding, especially with a small thickness of the plates. The upper and lower grips are located in the area of horizontal or vertical joints, which limits the minimum gap between the cladding plates, partially the elements of the device are viewed in vertical or horizontal joints.

The technical problem of the invention is the creation of a fastening unit for facing panels to NVF profiles, providing an increase in the degree of reliability and quality of fastening of facing panels with invisible (hidden) fastening when ventilated facades are installed.

The technical problem is solved in that the device for fastening the facing panels of the hinged ventilated facade according to the first embodiment, containing grips, a bar made with the possibility of fastening at least one of them, according to the invention is equipped with a second bar made with the possibility of fastening on it, at least one capture, with each capture made in the form of a plate, the first part of which is bent to form a different angle from 90 ° (blunt or sharp) angle relative to its second part, and ki are connectable with each other.

In one particular case, when at least one grip is secured with its second part on the corresponding bar and when the strips are connected to each other, the free first part of the at least one grip on each bar is inclined towards the other bar.

In another particular case, when at least one grip is secured with its second part on the corresponding bar and when the bars are connected to each other, the free first part of the at least one grip on each bar has a slope in the direction from the other bar.

Preferably, at least one slot is made on the first part of each grip to form at least one folded lobe.

In a preferred embodiment, each bar (5) has a cross-section made in shape as shown in FIG. 5, longitudinal slots are made on the bent edges of the bar opposite each other, and each grip is made with bent edges on the second part of the plate, made with the possibility of introducing into these slots and bending them from the back of the bar to secure the grip on the bar.

It is advisable that the first part of each capture had a rounded edge.

The technical problem is also solved by the fact that the device for fastening the facing panels of the hinged ventilated facade according to the second embodiment, comprising grips and a bar, according to the invention is equipped with at least two fasteners, each of which is made with the possibility of connection with the bar and with the possibility of fixing on at least one grip, each grip is made in the form of a plate, the first part of which is bent to form an angle other than 90 ° (blunt or sharp) relative to its second Asti.

In one particular case, when at least one grip is secured with its second part on the corresponding fastener and when the fasteners are connected to the bar, the free first part of the at least one grip on each fastener is tilted towards the other fastener.

In another particular case, when at least one grip is secured with its second part on the corresponding fastener and when the fasteners are connected to the bar, the free first part of the at least one grip on each bar has a slope in the direction from the other fastener.

Preferably, at least one slot is made on the first part of each grip to form at least one folded lobe.

In a preferred embodiment, each fastener (7) has a cross-section made in shape as shown in FIG. 14, with the possibility of installing it on a bar and fixing it.

In another preferred embodiment, slots are made on each fastener, and each grip is made with bent edges on the second part of the plate, made with the possibility of introducing into these slots and bending them from the back of the fastener to secure the grip on the fastener.

It is advisable that the first part of each capture had a rounded edge.

The technical problem is also solved by a gripper for fastening the facing panels of the hinged ventilated facade, made in the form of a plate, one (first) part of which is bent to form an angle different from 90 ° (blunt or sharp) relative to the other (second) part.

In addition, it is preferable that at least one slot is made on the first part of the plate to form at least one bent petal.

It is also preferable that the opposite edges of the second part of the plate are bent to secure the grip on the bar or on the fastener, while these edges and the first part of the plate are bent in different directions relative to the second part of the plate.

In this case, the first part of the plate preferably has a rounded edge.

The technical result of the invention is achieved by making slots for the grips not on the side ends, but on the back of the panel. Slots are performed at an angle to the surface of the panel. At the same time, there are no thin parts of the panel that can break off both during installation and during operation. As a result, the reliability of fastening panels increases and the amount of their waste is reduced. In addition, the placement of grips on the back of the panel allows you to reduce the gap between the plates to almost zero, which reduces the likelihood of precipitation getting into the illegal armed forces, and also eliminates the presence of visible elements between the panels, which improves the appearance of the building’s facade.

The grip 1, which is part of the device for attaching the facing panels of the hinged ventilated facade, is made in the form of a plate 2, one (first) part of which is bent relative to the other (second) part at an angle other than 90 °. In FIG. 1-3 shows a grip with a blunt bend angle, in particular 135 °. The bending angle may be sharp, as shown in FIG. 4. For better retention of the panels on the first part of the plate 2, at least one slot (notch) is made with the formation of at least one bent blade 3. In FIG. 1, 2 shows two petals 3. There may be one petal or more than two. The petals 3 are bent to the side of the plane in which the second part of the plate 2 lies. Other means for engaging the panel can be made: cuts for glue to enter into them, etc. In this case, the first part of the plate 1 preferably has a rounded edge in order to completely fill cut in the panel, performed by a round disk, to ensure maximum grip with the panel.

To ensure that the grip 1 is fixed on the bar or on the fastener, the opposite edges 4 of the second part of the plate 2 are bent to form tabs, while the edges 4 and the first part of the plate 2 are bent in different directions relative to the second part of the plate 2.

The device for fastening the facing panels of the hinged ventilated facade according to the first embodiment (Fig. 5-12) contains two strips 5 and grips 1 for fixing on it. The straps 5 are configured to connect with each other to form one strap. One, two or more grips 1 can be fixed on each bar.

When fixing one or more grippers 1 with its second part on the corresponding strip 5 and when connecting the strips 5 to each other, the free first bent portion of at least one capture 1 on each strip 5 can be tilted towards the other strip 5 (as shown in Fig. 10) or in the opposite direction (as shown in Fig. 13).

In a preferred embodiment, each plank 5 has a cross section made in shape as shown in FIG. 5, 7, providing the bar 5 with the necessary rigidity. On the bent edges 6 of the plank 5, longitudinal slots 7 are made opposite each other, into which the bent edges 4 of the grip 1 are inserted. On the back side of the plank 5, the edges 4 are bent to secure the grip 1 on the bar 5. The bar 5 may also have a different profile. The fixing of the gripper 1 on the bar 5 can be carried out in another way. The capture 1 can be performed without bent edges, and the strap 5 without slots. The grips can be fixed on the slats, for example, using rivets or self-tapping screws, or by welding, or other known means.

The device for fastening the cladding panels of the hinged ventilated facade according to the second embodiment (Fig. 14-19) comprises a bar 6 and grips 1, as well as at least two fasteners 7. Each fastener 7 is designed to be connected to the bar 6 and for fixing it has one or more grippers 1. There can be two fasteners 7 for fastening at the ends of the strap 6 (Fig. 17) or more, when the third or more fasteners 7 with grippers 6 are fixed in the middle of the strap 6 or evenly distributed on it.

When at least one grip 1 is secured with its second part on the corresponding fastener 7 and when the fasteners 7 are connected to the strip 6, the free first part of at least one grip 1 on each fastener 7 is inclined towards at least at least one other fastener 7 (Fig. 17-19) or in the direction from at least one other fastener 7.

In a preferred embodiment, each fastener 7 has a cross-section made in shape as shown in FIG. 14, with the possibility of its installation on the reciprocal external surface of the strip 6 and fixing on it.

In a preferred embodiment, slots 8 are made on each fastener 7 for introducing bent edges of the gripper into them and bending them from the back of the fastening element 7 to secure the gripper 1. As in the first embodiment of the device, the fastening of the gripper 1 on the fastening element 7 may be different way. The grip 1 can be performed without bent edges, and the fastener 7 without slots. Grips can be fixed on the fasteners, for example, using rivets or screws, or welding, or other known means.

When using the proposed devices for fastening the cladding panels (preferably ceramic plates) to the NVF profiles, they are performed along the edges of the panels 8 from the back of the slot 9 (cuts) at an angle of preferably 45 ° (± 5 °) to the back of the panel 8. With the thickness of the panel 8, equal to 10 mm, cuts 8 are performed to a depth of about 7 mm. With the large dimensions of the panels 8, the cuts 9 are also performed along the midline of the panel 8 or with a uniform interval along the width of the panel 8. The angle between the parts of the grip plate 2 is equal to the angle and the inclination of the cut 9 in the panel 8 or the angle 180 ° -α.

The device according to the first embodiment works as follows.

Fasten on each strip 5 one at a time, or two, or more grips 1. Insert the grips 1 into the cuts 9 of the panel 8 and connect the two strips 5 to each other, for example, using rivets. Fix the strap 5 on the profiles of illegal armed groups.

The device according to the second embodiment works as follows.
