Description

TECHNICAL FIELD

FIELD OF THE INVENTION The present invention relates to the field of construction of buildings and buildings, and more particularly to brackets for ventilated facades and their structures.

TECHNICAL LEVEL

The present disclosure provides a new ventilated facade bracket with sufficient and stronger mechanical strength to support the facade finishing panels while having extremely low thermal conductivity. The bracket is made of polymeric material by inserting reinforcing fiber made from basalt. The shape of the cross-section of the bracket resembles a rectangle with a central part removed, e.g. the shape resembles a U-shape. Also, when forming the bracket, different layers are formed from reinforcing fibers of different orientations, which provides additional mechanical strength. The polymeric materials used have significantly lower thermal conductivity than the metal used today.

GB2398580A (published August 25, 2004) discloses the construction of a bracket for use in construction, which is intended to provide sufficient mechanical strength while providing low thermal conductivity. The bracket is cited in the document cited as having a junction in a non-uniform material; the structure consists of two separate, mechanically strong parts separated by a layer of thermal insulation. In this way, a holder with a sufficiently low thermal conductivity is formed, but it is clear to the person skilled in the art from the design presented that such holder will not exhibit high mechanical strength. Also, the manufacture and installation of such a bracket is quite complicated.

Document LT 6136 B (published March 25, 2015) discloses a structural member of a structure, a ventilated facade bracket made of fiberglass composite with one of the cross sections being U-shaped. The cited document does not mention other materials which have higher mechanical strength, lower thermal conductivity. The cited document does not provide cross-sectional shapes that would provide greater strength. Also, the document cited does not provide the ability to direct the reinforcing fibers in the bracket in different directions.

The prior art examples described above have the following disadvantages:

- does not provide more carrier-friendly (mechanically strong, low thermal conductivity) materials,

- the cross-sectional shape does not give the maximum strength,

- the reinforcing fibers are oriented in one direction along the support, which prevents all strength-enhancing measures from being used,

-The bracket is made of non-homogeneous material, made of individual elements separated by a thermal insulation insert, which does not provide sufficient mechanical strength.

The new technical solution presented in this description does not have the drawbacks listed above.

PREFERRED EMBODIMENTS

This description shows the construction (1), (2), (7) of the ventilated facade bracket (Fig. 1, Fig. 2, Fig. 3). The bracket (1), (2), (7) is fixed at one end (can be fixed by means of auxiliary fastening means) to the structure, to the outside of the building's kites, or to other structural elements; on the other end of the bracket (1), (2), (7) the ventilated façade cladding, façade panels or other structural elements can be fixed (can be fixed with the help of fixing devices). In the space between the outer surface of the partition and the decoration, the facade slabs contain thermal insulation materials, ventilation spaces and other structural elements. The brackets (1), (2), (7) must be mechanically strong enough to support the facade panels. On the other hand, the bracket (1), (2), (7) must have as little thermal conductivity as possible, since it penetrates through the insulation layer on one side of the façade panels subjected to external temperature fluctuations and on the other end on the building envelopes which must be protected from outside temperature fluctuations. In other words, the bracket (1)> (2), (7) should be as thermally conductive as possible in order to minimize the transmission of thermal energy from the façade panels to the building envelope.

This description describes the construction of a ventilated facade bracket (1), (2), (7) with a new cross-sectional shape of the bracket (1), (2), (7), new to the bracket (1), (2), (7). made with materials used, new uses of those materials. The bracket (1), (2), (7) of the aforementioned structure is sufficiently mechanically robust and at the same time has a low thermal conductivity. The cross-sectional shape of the holder (1) (Fig. 1) presented in this description resembles a hollow quadrilateral (may be a rectangle, a square) with the middle part of one side removed, i. the shape resembles the shape of a square bracket, [only in addition to the bracket shape at each of the short sides ends, joins a portion of the edge that forms a perpendicular angle to each of said short sides and is directed toward the other short edge opposite. The shape described is reminiscent of the shape U, Short edges give extra mechanical strength to the entire structure of the bracket (1) when the bracket undergoes bending, and the bending force acts on the end of the bracket (1) to which the facade panels are fixed. or close to a parallel) plane that forms said short, terminating cross-sectional edge.

The pairs of opposite sides of the opposite sides that determine the shape of the cross-section may be of different lengths, i.e. the shape of the cross-section may be almost flat, i.e. one continuous border several times longer than the other boundaries to which this longer border joins.

Another cross-sectional shape of the bracket (2) described herein resembles the shape of a square bracket [i.e. short edges joined to one edge at different ends, which generally form a right angle with said long edge.

Another cross-sectional shape of the bracket (7) described herein resembles a rectangle of elongated shape (when the length of one side is at least several times the size of the other joining, angle-forming side). The corners of said rectangle may be rounded.

The construction of the ventilated façade bracket (1), (2), (7) described herein is novel in that reinforced composite materials are used to make the bracket (1), (2), (7), which, depending on the position of the bracket ( 1), (2), (7), formed with reinforcing fibers oriented in different directions.

Composite materials, in which reinforcing fibers are inserted, are used to make the carrier (1), (2). The composite materials of the present invention are various polymeric materials (thermoactive or thermoplastic) such as polyester resin, vinylester resin, epoxy resin and / or others. The reinforcing fiber-filling composite material is called a matrix. The matrix combines reinforcing fibers into a single structural material. The matrix consists of a base material and additional accessories that can give the base material additional material properties such as: ability to more accurately control the manufacturing process, change the color of the matrix, shape the desired surface texture of the product, change product resistance to various environmental factors (eg UV) reduce the cost of the raw material and I or other.

Reinforcing fibers are fibrous materials that reinforce, bind, and provide the polymer matrix with the required mechanical strength properties. There are two types of reinforcing fibers: specialty fibers (basalt, aramid, carbon and I, etc.) and natural fibers (hemp, sisal, jute, linen, cotton, bamboo, kenaf, banana, agave and I, etc.).

One of the uses of the present invention is basalt fiber, which is more resistant to aggressive chemical environments (acids, alkalis, salts, etc.), having a strength about 25% higher than Type E glass fiber, and a modulus of elasticity about 15% higher than Type E glass fiber. Due to the above-mentioned properties, the holder (1), (2), (7) can be manufactured with a smaller cross-sectional area, but can retain the same mechanical properties as the holders made with other materials, while reducing the cross-sectional area thermal energy transfer coefficient.

The mechanical strength properties of the reinforced composite article, bracket (1), (2), (7) largely depend on the orientation of the reinforcing fiber and the direction of the fiber filaments relative to the geometry of the bracket. If the bracket (1), (2), (7) is fixed at one end to the structure partitions and at the other end the façade panels are applied, the force acting on the end to which the panels are attached causes the lugs along the bracket (1), (2), (7) forms. Therefore, the reinforcing fibers are also worth orientating along the bracket (1), (2), (7) - thus achieving maximum mechanical strength. On the other hand, the bracket (1), (2), (7) may also engage in other directions. Therefore, in the present invention, reinforcing fibers oriented in different directions are used in the manufacture of the holder (1), (2), (7) depending on its cross-section. Also, the fibers themselves are of different types: continuous, longitudinal (when all the filaments are oriented parallel to each other), matting (non-woven fibers of multi-directional fibers), weft (non-woven, often low-weft) thickness (about 40g / m ² ) glass or polyester filament product).

In the case of the present invention, the core of the holders (1), (2), (7) is reinforced with longitudinal fibers (3), after which the outer surface of the article is further reinforced with a layer of matting and I or fabric (4). The outer layer (4) of the mat or fabric in this case takes over not only the transverse strain in the case of bending but also the internal strain caused by the shrinkage of the polymeric matrix during the polymerization.

A surface veil (5) is used to form a thicker layer of polymer on the product surface. This not only results in a better aesthetically pleasing surface but also strengthens the fibers inside the product against aggressive environmental factors.

In the case of the present invention, the brackets (1), (2), (7) are manufactured in elongated form without any change in direction. If the bracket or the bracket requires an angle, holes are made in the bracket (1), (2), (7). The holes are used to attach the brackets (1), (2), (7) to the angular profile (6) (Fig. 4, Fig. 5), which provides the required mounting position.

In the case of the present invention, a spring (8) of a specific shape is attached to the other end of the bracket (1), (2), (7) than the bracket is attached to the static kites. The aforementioned spring (8) makes it easier to attach a vertical structural element for mounting the facade panels.
