Description

Technical field

The present invention relates to systems of ventilated facades of buildings, and more particularly, to devices for fastening facade cladding panels that provide high-quality indoor performance.

State of the art

A known design of the fencing of buildings with thermal insulation, with the active removal of moisture and decorative decoration of the facades, containing a metal frame mounted using brackets on the wall of the building with profiles holding vapor-breathable insulation (RU, No. 2229573, M. class ⁷ : E04F 13/08, 2001).

The disadvantages of the analogue: the complexity of the design, lack of reliability and the need for deteriorating the appearance of the facade of the decorative strips for sealing joints of plates.

The closest to the claimed proposal, an analogue in technical essence and the properties shown, adopted as a prototype, is a facade hinged fence made of blocks, each of which contains a frame with fasteners and an inner lining forming an airtight cavity connected to the atmosphere through a channel and equipped with at least one heat shield and at least two heat shield layers, wherein the blocks are attached to the building by means of supports, one end of which is rigidly connected to the frame of the building an administration, and another with a block (RU, No. 2266379, M. cl. ⁷ : E04F 13/08, 2004).

The disadvantages of the prototype are the bulkiness of the structures and the limited air exchange regulated by special sensors with insufficiently high reliability of the devices.

Disclosure of invention

The objective of the invention is to increase the reliability of devices of facade fencing while ensuring high performance inside the building.

This task is ensured by the fact that the facade hinged ventilated fencing of buildings, including facade slabs, insulation, load-bearing profiles, attached to the load-bearing wall using brackets, passed through the insulation without a gap, and having two pairs of rails in which distance brackets are installed, fixed in the design the position of the facade slabs on the bearing profiles with the help of self-tapping screws, on the bent ends of the distance brackets are resting "P" -shaped swivel brackets with curved and rectangular shelves, and to ivolineynaya made of conditions in a reliable locking guides by turning through 90 °, a rectangular shelf into the groove of the upper or lower ends of the front plate, in the headspace set of guide rubber seals.

The grooves in the ends of the facade plates are made in the golden ratio, when the distance from the longitudinal axis of the groove to the inner surface of the plate is the average proportion between the thickness of the plate and the distance from the axis of the groove to its outer surface.

The upper and lower ends of the distance brackets are bent in the form of hooks, providing reliable support for the U-shaped swivel brackets.

The lower facade plates rest on the end L-shaped brackets included in the end grooves, which are attached with self-tapping screws to the bearing profiles.

Brief Description of the Drawings

Figure 1 shows a schematic general view of the proposed facade fence, figure 2 shows a U-shaped swivel bracket, figure 3 is a distance bracket, figure 4 is an end L-shaped bracket, figure 5 is a guide profile.

Figure 1 shows the wall 1 with insulation 2, attached to the wall 1 using brackets 3, passed without a gap through the insulation 2, bearing profiles 4. 5 - anchors, with which they are attached to the wall. The bearing profiles 4 have two vertical grooves 6 and 7. In the guides 6 and 7, distance brackets 8 are inserted, fastened with self-tapping screws 9 to the bearing profiles 4 in the design position of the facade plates. The distance bracket 8 has bent ends in the form of hooks that provide reliable support for the U-shaped rotary brackets 10, the rectangular shelves of which are included in the slots 11 on the upper and lower ends of the facade plates 12, and the curved shelves provide reliable interaction between the distance brackets 8 and the supporting profiles 4. The end of the lower facade plate 12 includes an L-shaped end bracket 13 having only one curved end.

The slots 11 in the ends of the facade plates 12 are made in the golden ratio when the distance from the longitudinal axis of the groove to the inner surface of the plate is the average proportion between the thickness of the plate and the distance from the axis of the groove to its outer surface.

This groove design determines the reliable long-term operation of the facade slabs, since, in particular, damage to the outer surface due to atmospheric and other influences will not reduce the load-bearing capacity of the slab reliably held by the bracket 10 for its inner part, which is more durable from the cutout 11.

In the guides 6 and 7, a rubber seal 14 is also installed, absorbing shock and other loads on the facade plates 12.

The U-shaped swivel bracket 10 is made of the following conditions: “sideways”, it must freely enter the slot of the guides 6 or 7, and when turned 90 °, it must be securely locked in them, and the bracket shelves must withstand the load from the weight of the facade plates taking into account wind and other influences.

The implementation of the invention

The presence on the outer side of the wall 1 of the insulation 2 provides savings of thermal energy inside the premises and the absence of air convection, creating comfort in the room at a lower air temperature (18-20 ° C).

In the summer, insulated walls do not heat up (especially from the sunny side), and the indoor air temperature does not increase by more than 23-25 ° С.

The reliability and durability of enclosing structures are increased, since the dew point moves from the inside to the outside, where the temperature is lower and where the condensate that evaporates due to the ventilation system of the curtain wall. Moreover, condensate does not form and does not evaporate inside the wall, where the temperature is higher.

The device is installed using the following technology.

The insulation 2 is stitched without a gap with the thin walls of the bracket 3, with which the carrier profile 4 is attached to the wall 1. In the guides 6 and 7 of the carrier profile 4, distance brackets 8 are installed, which are fixed in the design positions (with respect to the ends of the facade panels) with self-tapping screws 9. Then, in the groove of the guides 6 or 7, a U-shaped bracket rotatable 10 is inserted with its narrow lateral side and rotated 90 °. In this position, it is securely locked, since its thickness is already cut out in the guides, the curved shape allows you to have a significant contact area with the guides 6 or 7 according to the strength conditions, and the rectangular shelf is included in the end cut 11 of the facade plate 12.

The lower end of the lowest facade plate rests on the end brackets included in the end cutouts 11 of the front plates 12, the end brackets 13, attached by self-tapping screws to the guides 6 or 7 of the supporting profile 4. Rubber seals 14 are installed in the spaces of the guides 6 or 7 that are free of distance brackets 14, which perform damping functions sharp wind loads, reducing noise and deformation of structures, unloading a self-tapping screw due to the transfer of mass load from facade plates to the guide due to friction.

Thus, the claimed proposal has the following technical results: thermal energy is saved due to additional thermal protection, indoor comfort is improved due to insulation of the external wall, the reliability of building envelopes is improved due to the elimination of the danger of condensate accumulation and the simplicity of structures in which all aluminum takes up the load from the plates sub-structure, the sound insulation of the building and its appearance are improved, the mechanical strength of the fastening of the plates is increased, the operational costs of construction and maintenance of systems, it is possible to build in the winter, when the temperature is below 0 ° C.

The listed technical results of the claimed invention, which are the results of new properties of the proposed combination of features, determine its inventive step.
