Description

The utility model relates to the field of industrial and civil construction, namely to structures for heat-insulating cladding of hinged ventilated facades (NVF) of buildings and structures, and can be used to fasten 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 grip for attaching hinged ceramic granite panels to building facades in a hidden way (RU 2403355 C2, publ. 11/10/2010), which includes upper and lower fasteners, while the upper element is arranged to be placed in a longitudinal cut on the upper end part of the facing panel, and the lower element is arranged to be placed in a longitudinal cut on the lower end part of the facing 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 utility model is the creation of a grip for attaching the cladding panels to the NVF profiles, which provides an increase in the degree of reliability and quality of fastening of cladding panels with invisible (hidden) fastening when ventilated facades are installed.

The technical problem is 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 utility model 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 bending 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.
