Description

The invention relates to the field of industrial and civil construction and is intended, in particular, for attaching large-format hinged cladding panels of a ventilated facade to the base wall with the possibility of independent adjustment of each of the attachment points.

In the prior art, the use of cladding panels is widely presented, which can be both decorative - providing the aesthetic appearance of the building, and functional - providing heat or sound insulation, depending on the materials used. In addition to their appearance, cladding panels differ in material, size and type of fastening (visible, invisible). These fastenings are called "substructure" - a supporting system, an element responsible for fastening the facade material to the wall. Simplified, it can be described as a system of brackets on which vertical and horizontal guides are fixed, and elements with which the facade material is attached to the guides.

Known is a device for attaching the cladding of a hinged facade system (patent RU 2488669 E04F 13/00, published on July 27, 2013), containing vertical bearing profiles and support brackets. Each of the profiles includes a support part fixed fixedly on the surface to be faced and a composite and adjustable cantilever post connected to it. Each vertical bearing profile is fixed with its upper part fixedly at the free end of the cantilever post of the support bracket. The vertical bearing profiles are interconnected by means of expansion joints made with the possibility of deformation with a linear change in the length of the vertical bearing profiles.

The advantage of this technical solution is the ability of each fastening element - the compensator to maintain a given distance of the hinged elements from the surface to be faced, fixing their relative position with the possibility of adjustment - compensating for deformation with a linear change in the length of the vertical bearing profiles, that is, regulation of the offset.

The disadvantage of this solution is the impossibility of regulating large-format hinged cladding panels relative to the facade of the building in height and horizontal displacement.

Also known is a device for fastening facade slabs (patent RU 67134 E04B 2/96, published 10.10.2007), containing a bearing unit having profiles that, by means of ribs, engage with two opposite surfaces of the facade slabs, forming a tongue-and-groove connection, supporting a profile in the form of a bracket, fixed on the surface to be cladding, and an intermediate element connected to the supporting unit and to the supporting profile, according to the utility model, a factory facade plate with longitudinal grooves along the end horizontal surface is used as a facade slab, each and a support profile , and the intermediate element in the horizontal section has an L-shaped profile, one shelf of which faces the surface to be lined, while the other shelf of the intermediate element is intended for mounting the carrier unit. The support profile is fixed to the surface to be clad with a bolting kit. The intermediate element in the horizontal plane is also an L-shaped section with a shelf facing the surface to be lined. The bearing unit consists of two combined profiles, made in the form of a bar-holder of the upper and a bar-holder of the lower one, in cross-section of which are two aligned, U-shaped profiles, each of which contains a wall and different-sized side shelves perpendicular to it. The ends of the shelves are bent outward.

In this solution, the mutual arrangement of structural elements provides an increase in the accuracy and reliability of fixing the facade slab in the protective and decorative wall cladding and, accordingly, ensuring reliable invisible fastening of the cladding, making the facade appearance presentable and unique durability, increasing the fire resistance of the wall enclosure cladding due to the lack of fasteners in the panels invisible fastening.

However, the known solution has low functionality, since it does not provide the ability to adjust the position of the panel in space to the optimum.

Another well-known solution - a hinged ventilated facade (patent RU 103545 E04B 1/00, published on 20.04.2011) consists in the presence of the following structural elements: facade slabs, thermal and waterproofing protection, load-bearing elements passed without a gap through the thermal and waterproofing protection, made in the form of row-arranged anchor rods screwed through dowels into the wall of the building and having fixing elements at the free ends that ensure the installation and fastening of the plates, in which the fixing elements are made in the form of heads connected to the threaded ends of the anchors with couplings with locknuts with the possibility of longitudinal adjustment and subsequent fixation of their position. The heads are equipped with plate holders in the form of flanges and locking mushrooms. When the heads are turned by 90 °, the fungi penetrate the outer surface of the plates and press them against the flanges. The heads of each vertical row of anchors, loaded with the weight of the slabs, and anchors fixing the slabs along the lateral ends and located on the same horizontal, are connected to each other by strips-rods with holes for the tail parts of the heads with a pitch equal to the step of fastening in the wall of the anchors being connected, behind by installing strips on the heads and pressing them with couplings to the flanges.

The advantage of the analogue lies in ensuring the reliability of fastening due to an extensive network of anchor rods with fixing head elements.

The disadvantage of this solution is a weak adjustment system with many parts. Only the tension adjustment of each facade slab is provided without the possibility of spatial regulation.

The proposed invention is aimed at overcoming these disadvantages of the prior art.

The problem to which the present invention is directed is to provide the possibility of independent, smooth, precise adjustment of the position of each of the facing panels in space and relative to each other with the elimination of the free play of each of the parts by fixing the adjusted position. At the same time, the present invention solves the problem of adjusting the facing panel from above as possible without the need for access for this from the side or bottom of the panel.

Solving these problems, with the use of the present invention, technical results are achieved, which consist in simplifying the fastening of hinged cladding panels, (especially large-format) ventilated facade to the base wall, while ensuring the required reliability.

The specified technical results in the proposed invention are achieved thanks to the proposed fastening device, including a power bracket with independent adjustment of four points, installed on the wall of the base and fixed on the facing panels a counterpart.

The bracket consists of a fixed support, thrust and guide plates, upper and lower inserts connected to each other. The inserts are made with the possibility of limited travel along the guide plates in the direction perpendicular to the fixed support. Studs are located in the indicated inserts. At least one of the studs has an adjusting sleeve. The inserts are equipped with adjusting bolts. Bracket elements are made of cold rolled sheets without welding. The bracket elements are bolted and / or riveted.

The counterpart consists of a support and a carrier ikli. The support iklya is designed to be placed on one of the pins. The carrier is equipped with a vertically fixed adjustment bolt. The carrier iklya is arranged to be placed on another pin so that the said adjusting bolt abuts against the body of the adjusting sleeve.

The next section of the description provides information that details the proposed solution.

in fig. 6 is a side view of the fixing device when mounted to a wall of a base;

in fig. 7 is the same top view.

The fixing device for large-format hinged cladding panels of the ventilated facade (Fig. 3) includes a power bracket mounted on the base wall (Fig. 1) and a counterpart interacting with the bracket, fixed on the cladding panels (Fig. 2).

The bracket is made of cold-rolled sheets without the use of welding and is formed by a fixed support 1, stop plates 9, guide plates 8, movable lower 6 and upper 14 inserts. The inserts 6, 14 are made with the possibility of limited travel along the guide plates in the direction perpendicular to the fixed support 1. In these inserts 6, 14 there are pins 4. On at least one of the pins 4 there is an adjusting clutch 5. The pin 4 can include more than one clutch 5. Inserts 6, 14 are equipped with adjusting bolts 7. Bracket elements can be assembled both on bolts and rivets 11.

The counterpart interacting with the bracket and fixed to the bearing part of the cladding panels consists of a carrier ridge 12 and a support ridge 15. The support ridge 15 is made with a recess as shown in FIG. 2 in order to be able to place the insert 14 on one of the pins, the recess acts as a hook when installed on the pin. The carrier iklya 12 is equipped with a vertically fixed adjustment bolt 13 rigidly connected to it. The bearing iklya 12 contains a figured recess (hook) for the possibility of placing an insert 6 on another pin.

The fastening of large-format hinged cladding panels of the ventilated facade to the base wall by means of the claimed device is carried out as follows.

Bracket 1 is installed in the design position on the base wall using anchors interacting with the body of the bracket. By rotating the adjusting bolts 7, the movable inserts 6, 14 are set to the design position.

Bearing 12 and support 15 ikli are attached to the bearing parts of the facing panels.

Using a lifting technique, the cladding panel is lifted and hung with hooks and glue on the pins 4 located in the movable inserts 6 and 14. When installing, the supporting iklya 12 rests on the adjusting bolt 13 against the body of the coupling 5. (Fig. 3)

Next, the final adjustment of the removal is carried out by rotating the adjusting bolts 7 of the movable inserts 6, 14, and the horizontal position is adjusted by rotating the adjusting clutch 5 on the pin 4 and the height by rotating the adjusting bolt 13 of the carrier ikli 12.

FIG. 6 and 7 show an example of implementation of the invention - fastening of large-format glass fiber concrete panels. The cladding panels are hung and hooked onto the adjusting sleeves. The upper attachment points are load-bearing, that is, they perceive both the horizontal wind load and the vertical weight load. The lower attachment points are the support points and only take the wind load.

The adjustment of the upper and lower inserts 6, 14 is carried out independently - each with its own adjusting bolt 7, which makes it possible to set relative to adjacent panels independently of each other.

Adjusting clutches 5 by rotating the insert 4 on the hairpin adjust the position of the cladding panel horizontally along the facade.

By rotating the adjusting bolt 13 of the carrier and 12 adjust the position of the facing panel in height.

Thus, in the proposed solution, each attachment point is adjusted separately and independently. The upper points are regulated by open access from the top of the panel. The lower points require adjustment only along the extension, since the cladding panels are geometrically rigid structures and the adjustment of the upper points in height and horizontal displacement sets the corresponding position of the entire cladding panel.

If, after mounting and adjusting the upper points, it remains necessary to adjust the removal of the lower attachment points, then measure the amount of the required adjustment, raise the facing panel to the height necessary to access the bracket, make the necessary adjustments by rotating the adjusting bolt 7 of the movable insert 6 and lower the panel to the design position ... As shown, with only top access to the interior, each attachment point can be independently adjusted.

Thus, thanks to the proposed design, it is possible to attach two vertically adjacent cladding panels to one bracket (Figs. 6, 7), at the same time it is possible to adjust all attachment points from above, and not from the side, from below at their location as in analogs, which is significantly simplifies the fastening of hinged cladding panels of a ventilated façade, especially large-format ones, to the base wall.

An additional advantage of the proposed fastening device is independent, clear, smooth adjustment of the position of each cladding panel separately, which, on the one hand, simplifies the installation of the device to the wall, on the other hand, ensures reliable fastening of the panels due to the independence of the adjustment points and the independence of fastening each panel as a whole when facing the wall. grounds. The absence of unnecessary parts and connections due to the execution of the bracket elements from cold-rolled sheets without the use of welding, as well as the use of adjusting structural elements (in particular, bolts, couplings) also ensure the reliability of the proposed device.
