Abstract
Description
Subject matter of the invention
[0001] The subject of the present invention, as the title of the invention states, is a decontaminating facade, which can be an interior or exterior facade, consisting of elements that imitate plant leaves from nature in shape and color and are made of ecological, recyclable and lightweight materials, thereby achieving numerous advantages over the systems currently used both outdoors and indoors.
[0002] The present invention is characterized by the special design and configuration of all parts, resulting in a modular system that can be easily adapted to any environment and any required shape, consisting of small modules to facilitate handling, transport and installation, on which the leaves are attached that mimic the flora present in the environment in order to achieve better integration into the landscape and less aesthetic impairment.
[0003] The present invention thus falls within the field of architectural elements that clad or cover interior or exterior facades, in particular under decontaminating facades. Background of the invention
[0004] Several systems currently in use with similar purposes are known in the prior art, but these are based on materials whose maintenance is significantly more expensive, such as vertical gardens with natural plants, which consume a lot of water and incur very high costs during their lifetime, and are also exposed to environmental phenomena that can lead to their destruction, which is not the case with the present invention.
[0005] Therefore, the object of the present invention is to develop easy-to-install and cost-effective decontaminating facades by developing a facade such as the one described below, the essential features of which are contained in the first claim. Description of the invention
[0006] The subject matter of the present invention is essentially specified in the independent claim, and the different embodiments are specified in the dependent claims.
[0007] The present invention relates to a decontaminating facade made of fire-resistant composite materials coated with a photocatalytic material.
[0008] Photocatalytic materials are substances that, when exposed to light (usually UV light), trigger chemical reactions to decompose organic and inorganic pollutants such as nitrogen oxides (NOx), volatile organic compounds (VOCs), and dirt, converting them into harmless elements like water and carbon dioxide. The most common photocatalyst is titanium dioxide (TiO2), which, upon absorbing light, generates electrons and "holes" that react with air and water to form reactive free radicals, which break down the pollutants.
[0009] The facade consists of a series of modular elements that can be suspended from a facade, each modular element comprising a metal frame equipped with one or more suspension elements, preferably attached to the top profile of the metal frame.
[0010] The aforementioned metal frame is covered on its surface with a fire-resistant composite panel, on which a number of elements are attached that mimic leaves and plants from nature and are also made of a fire-resistant composite material, the entire arrangement being coated with a photocatalytic product to achieve the desired decontaminating effect.
[0011] In order to hang the aforementioned modular elements, hangers attached to the facade are used, which interact with the modular elements.
[0012] The leaves can have different sizes, shapes, and colors depending on the technical / aesthetic requirements of the respective system, which are usually determined by the end customer.
[0013] The system for attaching the leaves to the frame and the composite panel to the frame has sufficient mechanical strength to withstand the weather conditions expected at each installation site, which must be calculated and defined for each project.
[0014] The assembly is primed with a photocatalytic product that achieves the desired decontaminating effect.
[0015] The most important features of the system are: • Lightweight system with low weight, easy to install. • Sustainable, ecological and recyclable. • Fully adaptable to the customer's desired aesthetic, both in terms of shape and color. • Decontaminating, as described above. • Maintenance-free. • It prevents vandalism on open spaces in cities and offers a better aesthetic by imitating nature.
[0016] Unless otherwise stated, all technical and scientific elements used in this patent description have the meaning that a person skilled in the art in the field of this invention would normally understand. Methods and materials similar to or equivalent to those described in the patent description may be used in implementing the present invention.
[0017] In the description and the patent claims, the word "comprises" and its variants should not exclude other technical features, additives, components, or steps. For a person skilled in the art, further subject matter, advantages, and features of the invention will become apparent partly from the description and partly from the implementation of the invention. Explanation of the figures
[0018] To supplement the present description and to provide a better understanding of the features of the invention, a series of drawings are included as an integral part of this description according to a preferred embodiment thereof, in which the following are shown for illustrative purposes and without being limiting. Fig. Figure 1 shows the typical distribution of the hangers that are attached to the wall on which the architectural system is to be installed. Fig. Figure 2 shows a typical arrangement of several frames with the composite panel and the leaves on its surface. Fig. Figure 3 shows a typical plate with reference to a detail that is in Fig. 4 can be seen. Fig. 4 shows this in Fig. 3 mentioned details, in particular the arrangement of the various components of the typical frame. Fig. Figure 5 shows the suspension system for the panels and the attachment of the hangers to the wall. Preferred embodiment of the invention
[0019] A preferred embodiment of the proposed invention is described below with reference to the figures.
[0020] In Fig. Figure 1 shows that the decontaminating facade consists of a series of modular elements, each modular element comprising a metal frame 1 suspended from metal fittings 2, which are strategically placed on the facade and according to the hangers 1.2 ( Fig. 4) are arranged, which are preferably provided on the upper profile 1.1 of the metal frame 1.
[0021] In Fig. 2 shows the entire facade, with each metal frame 1 covered with a fire-resistant composite panel 3 on which a series of leaves or the like 4 are attached, imitating plants from nature and made of fire-resistant composite material.
[0022] Fig. Figure 3 shows a frame 1 which is provided with a series of hangers 1.2, wherein in the illustrated case the frame 1 has, in addition to its own frame, an intermediate profile 1.3 on which the aforementioned hangers 1.2 are also arranged.
[0023] In Fig. Figure 4 shows that hangers 1.2 are attached to the top profile 1.1 and the intermediate profile 1.3, which are parts in the shape of an inverted "L" that are attached to the top profile 1.1 and / or the intermediate profile 1.3.
[0024] Fig. Figure 5 shows how the modular elements are suspended using the suspension fittings 2, which, as can be seen, comprise a mechanical fastening 2.1 by means of a screw 2.3 and a hanger 2.2, which is a double-bent part that is attached to the wall at one end by means of the screw 2.3 and is slightly away from the facade on the other side to create a suspension space for the modular elements.
[0025] Having sufficiently described the essence of the present invention and the manner of its implementation, it is pointed out that its essential features can also be implemented in other embodiments which differ in detail from the one given as an example and for which the requested protection also applies, provided that its basic principle is not changed, altered or modified.
