Description

The utility model relates to ground-based construction, to cladding from the same type of building elements, in particular to the structures of facade metal cassettes, used, as a rule, for cladding ventilated facades of residential, administrative production, warehouse and other buildings.

Various variants of facade metal cassettes are known, which are analogues of the proposed utility model (see RF patent for utility model No. 121844 “Facade metal cassette (variants)”, publ. November 10, 2012, Bulletin 31).

A facade metal cassette is known, which is made in the form of a thin-walled box with a bottom and walls, at least two of the opposite ones are intended for mutual fastening of metal cassettes, the bottom is corrugated.

A facade metal cassette is known, at the bottom of which there is a light-scattering element, occupying most of the bottom and made at least in the form of one concavity that does not have surfaces parallel to the plane of the bottom.

A facade metal cassette is known, at the bottom of which there is a light-scattering element, occupying most of the bottom and made at least in the form of one convexity that does not have surfaces parallel to the plane of the bottom.

A facade metal cassette is known, at the bottom of which there is a light-scattering element, occupying most of the bottom and made at least in the form of one convex and one concavity, without surfaces parallel to the bottom plane.

Various forms of facade metal cassettes are known (see RF patent for utility model No. 131770 “Facade metal cassette (variants)”, publ. 08.27.2013, Bull. 24).

A facade metal cassette is known, made in the form of a thin-walled box with a bottom on which unidirectional rectilinear corrugations are made, and walls, at least two of the opposite ones are intended for mutual fastening of metal cassettes, unidirectional rectilinear corrugations are made with an indentation from each other, made identical, between unidirectional corrugations are made of rectilinear corrugations, perpendicular to them and located at the same pitch.

A façade metal cassette is known, where unidirectional rectilinear corrugations are made with the same spacing from each other, between them there are rectilinear corrugations, perpendicular to them and located with the same spacing, while the corrugations, perpendicular to the unidirectional corrugations, located on different sides of the latter, are made with a spacing relative to each other.

A façade metal cassette is known, in which the longitudinal corrugations are made wavy and spaced apart from each other; between them there are transverse corrugations located in increments.

A facade metal cassette is known, in which convexities and (or) concavities are made at the bottom, convexities and (or) concavities are made throughout the bottom of the metal cassette and have adjacent edges.

The main disadvantage of the known designs of facade metal cassettes is their deformation due to thermal expansion, which leads to the use of smaller metal cassettes or an increase in the thickness of the metal, which leads to an increase in its cost, and in general, of the entire structure. Since facade metal cassettes are deformed due to thermal expansion, they are therefore forced to produce smaller cassettes or increase the metal thickness to 1.2 mm, which also leads to higher costs and an increase in the load on the structure of the structure. Due to the fact that metal is a good conductor of sound waves, which lead to vibration of facade metal cassettes and various abnormal weather conditions (hurricane, rain, winds).

It should be noted that from thin metal (0.5-0.45 mm) it is not possible to produce metal cassettes of large sizes, for example, such as 1210x585 mm.

Common essential features with the above-mentioned known facade metal cassettes, which coincide with the essential features of the proposed technical solution, are that the facade metal cassette is made in the form of a thin-walled box with a bottom and walls, at least two of the opposite ones are intended for mutual fastening of metal cassettes.

The technical task is to create a façade metal cassette, which will ensure the rigidity of a structure made of thin-sheet galvanized metal, will reduce the cost for the buyer due to less consumption of guides for a ventilated facade, as well as reduce the load on the structure and elements of the building and ensure a presentable appearance.

Increasing the rigidity of the facade metal cassette will reduce deformation due to thermal expansion, their vibration during sound waves and various abnormal weather conditions, as well as changes in the profile of the metal cassette will significantly reduce the reflective properties.

The task is achieved that on the facade metal cassette, made in the form of a thin-walled box with a bottom and walls, at least two of the opposite ones are intended for mutual fastening of metal cassettes, stiffening ribs are made on the outer or inner sides of the box, while the stiffening ribs are on the outer or the inner sides are made perpendicular from the middle of the opposite sides or diagonally from the corners of the box, and the stiffening ribs are made at an angle to the center of their intersection, forming segments on the outer or inner sides of the metal cassette, and the height of the recess in the center of the box at the intersection of the stiffening ribs is made equal to more 1/2 the height of the box.

The main distinctive features of the proposed design of the façade metal cassette are the presence of stiffeners, the formation of segments on its outer and inner sides of the box, as well as the determination, experimentally and by calculation, of the deepening of the intersection point of the stiffeners, equal to no more than 1/2 the height of the metal cassette box, which made it possible to achieve the above technical result when using them for cladding ventilated facades of both residential and administrative buildings.

The applicant does not know the design of the facade metal cassettes, which represent the totality of all the features characterizing the proposed utility model, which indicates the novelty of the proposed object.

The proposed façade metal cassette is illustrated in the drawings:

in fig. Figure 1 shows a general view of a façade metal cassette with stiffening ribs made diagonally from the corners on the outer side of the box;

in fig. 2 - general view of the façade metal cassette with stiffening ribs made on the outer side of the box from the middle of the opposite sides;

in fig. 3 - section 1-1, side view of a facade metal cassette with stiffeners made on the outside of the box, diagonally from the corners;

in fig. 4 - section 1-1, side view of a facade metal cassette with stiffeners made on the inside of the box, diagonally from the corners;

in fig. 5 - section 1-1, side view of a facade metal cassette with stiffeners made on the outside of the box, from the middle of the opposite sides;

in fig. 6 - section 1-1, side view of a facade metal cassette with stiffeners made on the inside of the box, from the middle of the opposite sides;

in fig. 7 - section 1-2, side view of the facade metal cassette at the intersection point of the stiffeners made on the outside of the box;

in fig. 8 - section 1-2, side view of the façade metal cassette at the intersection point of the stiffeners made on the inside of the frame.

The facade metal cassette is made in the form of a thin-walled box 1 with a bottom and walls, at least two of the opposite sides 2 and 3 are intended for mutual fastening of metal cassettes.

On the outside of box 1 there are stiffening ribs 4 and 5.

It should be noted that stiffeners 4 and 5 can be made both on the outer and inner sides of the frame 1 of the façade metal cassette.

A common distinctive feature of all proposed design options for façade metal cassettes is the presence of stiffeners, the formation of segments on its outer or inner sides of the box, as well as the deepening of the intersection point of the stiffeners to no more than 1/2 the height of the metal cassette box.

Using sheet-bending equipment, stiffeners 4 and 5 can be made perpendicularly from the middle of opposite sides or diagonally from the corners of the box at an angle to the center of their intersection, thereby forming segments on both the outer and inner sides of the box.

Moreover, the height of the recess h in the center of the box at the intersection of the stiffeners is determined experimentally and by calculation. Going beyond the limit, namely more than 1/2 of the height of the box H of the metal cassette, does not ensure the specified technical result in combination with all the essential features used in the proposed design of the façade metal cassette.

Facade metal cassettes are one of the most convenient materials for installing a ventilated facade. Such a system for protecting the external walls of a house is especially beneficial both for maintaining a comfortable microclimate in the room and for protecting the walls of the building from aggressive influences from the outside. The principle of a ventilated façade is that space is maintained between the exterior finishing and the wall for free air circulation. The light weight and ease of fastening of the cassettes already solves half of the problems in arranging the structure.

Facade metal cassettes are installed directly on a profile frame made of galvanized or stainless steel. Universal blind rivets or self-tapping screws are used as fastening elements.

Facade metal cassettes are molded sheets of galvanized steel with a polymer or powder coating for protection against corrosion. They are used for cladding the facades of buildings and structures under construction and reconstruction for residential, public and industrial purposes.

During installation, a vertical or horizontal-vertical fastening system is usually used. The identity of the frame and cladding materials reduces the likelihood of corrosion due to the formation of a galvanic couple.

The main advantages of the system for fastening metal cassettes include: the possibility of use on objects under construction and reconstruction; ease of replacement of individual structural elements in case of mechanical damage; universal rivet connection; high degree of corrosion protection; high speed of installation work.

The work procedure is strictly regulated, so there are practically no problems with installation. If part of the facade is damaged, then there is no need to carry out a complete repair. It is enough to dismantle damaged cassettes and replace them with new ones; the proposed design successfully allows this. The weight of the curtain wall façade made from the proposed metal cassettes for the building's load-bearing capacity is within normal limits.

The proposed design makes it possible to manufacture the proposed metal cassettes of various sizes for a specific building, taking into account its architectural features and due to the variety of colors, a ventilated facade made of metal cassettes will decorate any building.

The proposed design of facade metal cassette is beneficial both for maintaining a comfortable microclimate in the room and for protecting the walls of the building from aggressive influences from the outside. The principle of a ventilated façade is that space is maintained between the exterior finishing and the wall for free air circulation.

The proposed design of façade metal cassettes with stiffening ribs makes it possible to reduce vibration from sound waves and increase the protection of the façade from any adverse weather influences (rain, sudden and frequent temperature changes, ultraviolet radiation, etc.).

The design features of the proposed facade metal cassette allow its installation in a very short time.

The installation technology of the proposed facade metal cassette is simple and good in that, if it is necessary to repair part of the structure, it can be easily replaced.

Widespread use of the proposed design of facade metal cassette will ensure the rigidity of the cassette structure made of thin-sheet galvanized metal, will reduce the cost, reduce the load on the structure of the structure, eliminate deformation due to thermal expansion, vibration during sound waves and various abnormal weather conditions, as well as changes in the profile of the metal cassette will significantly reduce reflective properties.

It should be noted that the proposed design makes it possible to manufacture the proposed metal cassettes of various sizes for a specific building while maintaining the specified technical result and, in general, will improve the presentability of the appearance of the building and create its individual style.
