Description

The group of inventions relates to the construction and repair of buildings and structures for civil, industrial and agricultural purposes, in particular to fencing systems of buildings with thermal insulation and decoration of external walls and facades, and can be used both in the construction of new structures and in the reconstruction and modernization of buildings, as well as buildings in operation.

Various methods for coating or wall cladding are known. Usually they relate to the cladding of an existing old wall, on the one hand, with an additional layer of insulation, and on the other, with a new outer finishing layer. Coating such wall or similar load-bearing structures using cladding cassettes or elements is a quick and convenient way to give a new look to an old wall, while simultaneously improving its other characteristics.

As an example of such a cladding and design, used in this case, we can cite the patent of Finland N 68699, IPC E04F 13/08, publ. 10.10.85, according to which a coating of a metal sheet reinforced with a separate reinforcing structure is attached to the old wall, and a layer of additional insulation, such as glass wool, is placed under this coating. Such a wall cladding device is quick and convenient, but differs in relative multi-detailness, since it includes a large number of separate operations and, as a rule, uses many small fasteners that must first be fixed to the specified wall, after which the cassette is attached to to these details.

Other constructions and devices used in a similar situation are also known from the patent literature, but they are basically even more complex and suggest the presence of a large number of separate elements interconnected during installation.

Facing cladding elements are also known, including various materials with a surface layer on both sides. Such structures are difficult to adapt to cover existing walls. When installing such structures, as a rule, one also has to deal with a large number of small parts.

Another disadvantage of the known structures of fencing with insulation is that their installation requires accurate placement of fastener parts in usually very precisely defined places of facing elements and wall or similar load-bearing structures. This can be especially difficult when restoring existing structures in a building site, as this work should be carried out on the street, mainly at a height, and often the quality of the wall to be lined is such that it is difficult to find a good and reliable place to install the fastener where it needs to be installed. In almost all cases, the cladding of the outer walls of buildings and structures encounter a large amount of manual labor, and in fact, none of the known methods for the production and installation of structures with thermal insulation, cladding cassettes and elements can in the full sense of the word be called industrial.

A known design of fencing with thermal insulation with active removal of moisture, including load-bearing, enclosing elements and at least one vapor-breathable heat-insulating element. The heat-insulating element is made combined, consisting of a vapor-breathable heat-insulating layer and a ventilated air gap, at least on one side facing the external air environment, and from the side of the room the heat-insulating layer is facing the enclosing element, which is perforated, and with the external the side is in communication with the external air, at least through a ventilated air gap with the possibility of free penetration of water vapor from inside the building to the outside, wherein the cross-sectional area of the air gap for 1 running. m of the width of the element is not less than 1.5 times the total area of the perforation holes of the enclosing element in the area of the enclosure with a length or height equal to the length or height of the element, respectively, depending on its spatial orientation in the enclosure or the distance between adjacent openings communicating the vented layer with the surrounding medium, and a width of 1 m (see RF patent No. 2144114, IPC EV 1/70, 10.01.2000).

Closest to the proposed invention is the design of the fencing with thermal insulation and decorative decoration of the facades, comprising a frame formed by metal profiles fixed to the wall of the building, a heat-insulating element formed by insulation and air gap, and facade panels, the seams between which are covered with strips (see patent RF №2229573, IPC E04F 13/08, publ. 27.05: 2004).

The disadvantages of the known designs is that they are complex and do not provide fast enough installation.

Closest to the proposed invention - a facade panel for the design of fencing with thermal insulation and decorative decoration of facades - is a panel according to ed. St. USSR No. 863803, IPC E04F 13/00, publ. 09/15/1979. The panel is a front profile with upper and lower bends of the sides.

Closest to the proposed invention - the slat strip for the design of fencing with thermal insulation and decorative decoration of the facades - is a flexible strip strips described in the same source (see SU No. 863803).

The objectives of this group of inventions is to increase the thermal insulation of the external walls of residential and public buildings by creating closed air spaces, as well as creating a set of cladding elements, which, along with lightness, durability, simplicity and reliability of installation, also have thermal insulation, good appearance and environmental cleanliness.

The tasks are achieved with the achievement of relevant technical results due to the fact that in the design of fencing with thermal insulation and decorative decoration of facades containing a frame formed by metal profiles fixed to the wall of a building, a heat-insulating element formed by insulation and air gap, and facade panels, seams between which are closed with slat strips, between the ends of the facade panels on their supporting platforms installed mortgage heat-insulating elements, facade panels and splint e strips are interconnected on a "wedge lock" embedded in the embedded insulating elements, the facade panels for use on the latest building corners are L-shaped.

In addition, the width of the supporting areas of the front panel is not more than 0.5 of the width of the metal profile, respectively.

In addition, the insulation and embedded heat-insulating elements are made of polyethylene foam, and the front panels and strips are made of unplasticized polyvinyl chloride.

In addition, the slatted strip is mounted flush with the front surface of the facade panel, and steps are made at the ends of the latter on the front side.

In this case, the front panel for the construction of fencing with thermal insulation and decorative decoration of the facades is made in the form of a three-layer panel of unplasticized polyvinyl chloride with intermediate channels in the form of rectangular cells, a wedge protrusion is placed in the upper part of the panel end, a supporting platform in the lower part, and on the front surface steps are made along the edges.

For the second option, the facade panel in the proposed design of the fence can also be made in the form of a three-layer panel of unplasticized L-shaped polyvinyl chloride with intermediate channels in the form of rectangular cells, with a wedge protrusion placed at the top of the panel ends, and a support platform at the bottom and steps are made on the front surface at the edges.

The stripping strip in the proposed design of the fence can be made in the form of a U-shaped strip with shoulders made of unplasticized polyvinyl chloride, the vertical expanding walls of which have the form of wedge hooks in cross section with the formation of a plastic hinge at the base of the strip, and the cross-member is made straight, while the expanding walls are made with bending inward with an angle of inclination to the vertical of 10-15 °.

For the second option, the slat strap can be made in the form of a U-shaped strap with shoulders made of unplasticized polyvinyl chloride, the vertical expanding walls of which have the form of wedge hooks in cross section with the formation of a plastic hinge at the base of the strap, and the cross-member is curved, while the expanding walls are bent inward with an angle of inclination to the vertical of 10-15 °.

figure 2 - the first embodiment of the front panel, General view;

figure 3 is the same, the second embodiment for the use of facade panels at the corners of the building;

figure 4 is a first embodiment of a slat strip, general view;

figure 5 is the same, the second embodiment of the slat strip.

The design of the fencing with thermal insulation and decorative decoration of the facades consists of a frame formed by rectangular metal profiles 1 mounted on the wall of the building, a heat-insulating element formed by insulation 2 and an air gap 3, between the building wall and the elements of the front fence, and front panels 4 and 5. Seams (gaps) between the ends of the front panels 4 and 5 are filled with embedded heat-insulating elements 6 and closed with slats 7.

Metal profiles 1 have a rectangular shape and can be made of galvanized iron or stainless steel, attached to the wall of the building using anchor bolts 8.

Insulation 2 and embedded heat-insulating elements 6 are made of polyethylene foam with a thickness of 35 to 40 mm, for the manufacture of which low-pressure polyethylene is used as raw material.

Facade panels 4 and 5 are made in the form of a three-layer panel with rectangular channels 9 in the form of honeycombs of rectangular shape, steps 10 are made on the front side of the panel, a wedge protrusion 11 is placed at the top of the end face, and a support platform 12 at the bottom. For use facade panels at the corners of the building, panel 5 is L-shaped. Facade panels 4 and 5 are mounted on metal profiles 1 by self-tapping screws 13 with their supporting pads 13. Facade panels 4 and 5 are made of unplasticized polyvinyl chloride.

The slat strips 7 are made in the form of a U-shaped strap with shoulders made of unplasticized polyvinyl chloride, the vertical expanding walls of which are in the form of wedge hooks 14 with the formation of a plastic hinge 15 at the base of the strap, and the cross-member is made straight or curved, while the expanding walls are bent inward with an angle of inclination to the vertical of 10-15 °. To give rigidity to the slat strips 7, stiffeners 16 are placed on the inner side of the cross members.

Installation of the design of the fence with thermal insulation and decorative decoration of the facades is as follows.

Metal profiles 1 are attached to the outer wall of the building with anchor bolts 8. Profiles 1 are set in such a way as to create a single plane for installation. The distance between the profiles 1 is determined by a template having the size of a decorative decorative panel with thermal insulation (DTI-panel), consisting of heat-insulating materials 2 and facade panels 4 and 5. glued to each other. The metal profiles 1 are vertically fixed with self-tapping screws 13 of the DTI-panel, supporting platforms of 12 panels 4 and 5 provide the necessary air gap 3. The entire installation is carried out by two people, regardless of the season. After installing the DTI-panel for docking, the docking elements (not shown) are inserted into the cellular channels, onto which another DTI-panel is mounted vertically. And so on. Thus, the resulting front surface does not have stitches, the resulting joint between the DTI panels is less than 0.1 mm. After the installation of two vertical rows of DTI panels, the joints between them are closed with strips 7, after laying on the supporting platforms 12 embedded heat-insulating elements 6. The strips 7 and two adjacent DTI panels form a lock connection on the principle of a "wedge lock". It is possible to pull out the strip only using a special device.

The present invention allows for exterior decorative decoration with thermal insulation of buildings and structures that meets current requirements both in the case of the construction of new buildings, and during the reconstruction of existing ones. This became possible due to the fact that the used DTI-panels contain a panel of unplasticized polyvinyl chloride - a material with a good set of mechanical and thermophysical parameters and a guaranteed lifetime of 50 years. At the same time, the three-layer honeycomb structure of the panel (20-26 mm thick) makes it possible to absorb wind loads with minimal deflection with a minimum weight. Connections of DTI-panels and strips according to the principle of “wedge lock” provided the possibility of their reliable fastening on the wall according to simplified technology without fastener parts.
