DESCRIPTION

Translucent modular prefabricated for transmission of light and information in interiors and manufacturing method

technical sector

The present invention, as stated in the title of this report, refers to a prefabricated modular construction that is especially suitable for use in interiors of homes, office premises and tertiary buildings. Tertiary is understood as those properties that are intended for one or more economic activities, whose purpose is the provision of services to the public, companies and organizations. This context includes hotels, markets, museums, interpretation, cultural and civic centers. The sectors to which this invention is linked are: construction, materials technology, industrial technology and production, and information and communication technologies.

Background of the invention

The transmission of light through originally opaque construction systems is relatively recent. The main objective that is intended to be achieved with the execution of translucent construction elements is the transmission of light through its surface, either as a complementary lighting method or with decorative motifs. The elaboration of these light-transmitting construction materials can be carried out on site or in a prefabricated way in the form of plates and panels of various geometries, always trying to maintain the mechanical performance of the original materials and optimal and economic design conditions. .

Plaster, or plaster in its absence, is one of the most commonly used materials for the industrialization of prefabricated plates and panels for the interior of homes. It is a pulverulent material composed of dihydrated calcium sulfate that, mixed with water, hardens quickly, generating a slight exothermic reaction during setting. In turn, the plaster has excellent technical features for use in interior walls, due to its high capacity for hygrothermal regulation, its good acoustic behavior, its finish satin and warm, and its good resistance to fire, since when it comes into contact with it, it loses the water molecules it contains in its composition and reduces the spread of the flame.

However, although currently the use of dry partition walls, cladding for false ceilings and prefabricated modular interiors are widespread in the construction industry, their incorporation into this sector has been slow and gradual, since initially they did not have a good acceptance as a consequence of the appearance of cracks due to deformation, their brittle breakage and the unstable behavior of the union joints. Fortunately, many of these drawbacks have already been resolved and there is a large number of investigations that have offered an answer to these problems, either by incorporating additives in the composition of the prefabricated material, or by reinforcing it with synthetic or natural fibers, trying to always to find the best relationship between the dimensions of the precast and its technical performance. Even so, progress is currently being made in the search for new types of prefabricated elements for interiors that improve existing alternatives on the market.

Some of the most relevant localized examples related to the prefabricated element described in the present invention are set out below.

Patent RU2011124870A describes a light-emitting partition for use in buildings. Said patent shows a partition that has a light-emitting surface, emission light sources and that in turn incorporates fiber optics in its composition. However, the present invention differs from the one described above in that it presents a matrix distribution of the optical fiber, embedded in a plaster matrix and containing an auxiliary reflective substructure, which allows the light of the point emitting sources located on the face to be focused. later. Therefore, the invention object of this document is not related to patent RU2011124870A and they are not comparable.

Patent CN102807343A refers to a type of translucent concrete made with white cement, lime and the addition of glass fibers, as main elements, and the addition of chemical compounds such as barium nitrate and sodium silicate. The purpose of this invention is to allow the passage of part of the light that has across from this material. This material is proposed both for its prefabrication and its elaboration in situ. Unlike this, and as will be seen in the following sections, the invention object of this document defines the orientation of the optical fibers, in addition to defining the intention or purpose of the transmitted light. In this sense, the present invention refers to the production of prefabricated products and cannot be carried out on site. The material is also completely different from the one presented in this invention, since plaster or plaster for interiors is used instead of white cement.

Patent KR101780322B1 refers to a light pole with an optical fiber insert on its surface. The post described in the aforementioned invention is made of wood, and optical fiber is intentionally inserted into it with the idea of representing images or symbols once illuminated, thus serving as a decorative motif. As will be indicated in the following sections, unlike this one, the invention described in this report is made in plaster and is especially designed for interiors of buildings. In addition, the optical fiber is distributed in the form of a matrix and the lighting of the different light points is carried out with the help of a controller that organizes the LEDs located on the rear face in on, off and color. Therefore, they are not inventions that are related in composition and materials used for their preparation.

Patent CN106121122A describes a light-transmitting decorative composite panel. It is a prefab that uses LED lighting with decorative motifs and that can be used for the execution of false ceilings and partition walls. However, said invention does not reflect at any time the incorporation of optical fiber in matrix form on its surface as a light-transmitting element. Therefore, the elements used in its preparation and the distribution of its components are different from those shown in the patent object of this invention, as will be seen in the following sections.

Patent EP2410103A2 refers to a concrete based on a special mortar lightened with granulated cork to which optical fiber is added in a random arrangement. The purpose of this invention is twofold, on the one hand, to lighten the weight of the concrete and, on the other, to transmit light through it. As will be indicated in the following sections, unlike this invention, the arrangement of the optical fibers in a matrix form of the present invention is completely intentional and needs to be arranged in this way for its correct operation. Furthermore, the base material is concrete as opposed to the plaster used in the present invention. In turn, the presence of a reflective grid to channel the light obtained from the emitting points, reflects how both inventions are not related either in the composition or in the arrangement of the materials used.

Utility model CN205777080U shows a light-transmitting concrete deck with decorative motifs, made with fiber optic and fiberglass layers. As will be indicated in the following sections, the present invention shows several differences with respect to said utility model, firstly, the base material is plaster and it is designed for use indoors, secondly, the optical fiber it is arranged in a matrix and orderly way, and, thirdly, the controlled lighting is carried out by means of a channeled LED matrix and regulated by means of a controller. Therefore, both inventions are not comparable.

Patent BRPI0801598A2 also refers to a concrete compound with optical fibers, but these are randomly dissolved inside the concrete, which means that only those that are in contact with the surface can transmit light through it. As will be indicated in the following sections, unlike this, the present invention intentionally arranges the fibers so that they cross the entire surface of the panel and the light transmission is maximum. In addition, said invention uses a concrete or cement matrix, a conglomerating material that differs from the plaster or plaster used in the present specification of the invention.

Accordingly, no material currently exists that meets the terms of this invention or is included within its attributions.

Description of the invention

The present invention falls within the group of industrial prefabricated elements, showing a construction element specially conceived for its application in false ceilings and interior linings. It is a construction system with a high degree of industrialization, easy installation and that solves two construction needs in an innovative way. On the one hand, act as a partition horizontally or vertically, and, on the other hand, to serve as lighting support for interiors with decorative or signage purposes through the transmission of information. In this way, a new finish is created, easy to elaborate and valid for any type of building, from residential to tertiary and offices.

The prefabricated modular construction described in this document is specially designed for the production of translucent plates and panels, capable of transmitting light with decorative motifs and signage information into the interior of the room where they are located. In this way, the prefabricated elements made with the described system would be used for the execution of cladding and interior partitions on a preferential, but not exclusive, basis.

The prefabricated object of the invention comprises:

- a plate that has an anterior face and a posterior face,

- a plurality of fiber optic elements embedded in the plate and distributed on the surface of the plate and having a front end located on the front face of the plate and a rear end located on the rear face of the plate so that the fiber optic elements pass through the thickness of the plate,

- a plurality of light emitters located on the rear face of the plate and configured to illuminate the rear end of the fiber optic elements so that said lighting is transmitted to the front end of the fiber optic elements.

The present invention consists of a prefabricated system made up of a plate, for example, of plaster containing a matrix of optical fibers that cross it from one end to the other on its surface, allowing the passage of light through them. This plate can be reinforced with a fiberglass reinforcing mesh embedded in the plaster matrix. In turn, this plate can be placed behind a grid of reflective material, preferably made with a polished metallic material such as aluminum, and on this, a matrix of LED lighting points that, with the help of the aforementioned grid, will reflect and They will conduct the light through the optical fiber from one end of the board to the other organized by a controller.

The material taken as the basis for the preparation of the prefabricated part can be made up, for example, of any type of plaster or commercial plaster as a conglomerating material, the use of plaster type E-35 or similar being preferable since its good mechanical performance has been verified. , as long as a water/binder mass ratio of not less than 0.70 and not greater than 1 is maintained.

The E-35 plaster is made up of SO4Ca-^H2O (hemihydrated calcium sulfate), which can incorporate additives in its composition responsible for setting regulation and has a minimum flexotraction resistance of 3.5 N/mm2. This type of material is frequently used in construction as a binder for the execution of prefabricated partitions and plates for false ceilings. In the panel proposed in the present invention, the E-35 plaster or similar has a water/plaster mass ratio of 0.70. It is necessary to highlight that the water included in the mass ratio is kneading water, this being the necessary for the mixture to acquire a workable consistency and the plaster to harden adequately, whose content can be determined by standardized methods, such as saturation kneading method or the paste fluidity measurement method.

The reinforcing mesh for the prefabricated panel would be specially designed to be made using some type of synthetic fiber, such as basalt, glass, carbon or polypropylene. However, it would be possible to use natural fibers duly positioned on the central surface of the prefabricated element, and in no case would it be possible to use metallic steel meshes due to their incompatibility with the plaster material that makes up the matrix of the target plate or panel. of the invention. The objective of incorporating this fiberglass mesh in the central position is to add stability to the prefabricated part and improve the flexotraction resistance of the panel or plate, which may be reduced as a result of the incorporation of the optical fiber in matrix form.

For its part, the optical fiber used to make the light-transmitting matrix that incorporates the prefabricated plaster would be specially designed to be of the plastic type (POF), although it is also possible to use other types such as glass optical fibers. It is necessary to point out that the optical fiber must be incorporated during the manufacturing process, before the hardening of the plaster material that forms the precast. Also, it is convenient to previously introduce a length of fiber at each point of the matrix that is incorporated into the panel, greater than the thickness of the precast, to later make a clean cut perpendicular to the axis of the fiber, so that it is completely embedded inside of the precast. In this way, it is possible to avoid possible imperfections in the cut area of the fiber that crosses both ends of the precast, which can harm the transmission of light that runs from one end to the other of the precast through its surface, especially in the case used fiber optic glass.

As for the reflective grid that is placed on the surface of the prefabricated part that is not visible from inside the room where it is applied, it is convenient that it be made with a material with a polished finish and that it channels the light towards the points of fiber optics that are incorporated into the prefabricated. In the system proposed in the present invention, a metallic aluminum grid has been chosen, with quadrangular perforations and a thickness of not less than 3 cm, the dimension of the grid being such that, in the center of each square of those that make up the grid, a light-transmitting fiber optic point is placed.

Finally, as light emitting points in an example of embodiment, the location of LED strips located on the upper face of the reflective grid has been chosen, so that each light emitting focus illuminates vertically and aligned with each point of the matrix of light. optical fiber. The choice of LED lighting points is preferential and indicative, but not limiting, and it is possible to place other types of light sources. These LED strips are connected to a microcontroller (such as those available in Arduino systems, but not only limited to these) that is responsible for organizing their on and off cycles, as well as their light intensity, for reasons of both decoration or with the intention of transmitting information to the people located inside your room.

Therefore, the object of the present invention, unlike the materials and prefabs described in the state of the art, is to present a panel, for example, plaster, specially designed for lighting and transmitting information inside homes. . The described system can be used by varying its geometries both for the execution of false ceilings, and for the elaboration of luminous interior partitions. In this way they can be represented with the help of, for example, a controller and some LED strips arranged on the rear surface of the panel, various geometric shapes and alphanumeric characters that can be viewed from inside the room where the prefabricated is located.

Another object of the present invention is a method of manufacturing a translucent modular prefabricated element for transmitting light and information indoors, characterized in that it comprises the following steps:

- providing a mold of at least one plate having a front face and a rear face,

- locating on the surface of the mold a plurality of fiber optic elements that have a front end and a rear end so that they will cross the thickness of the plate,

- pour a mass from the plate into the mould,

- harden the mass of the plate,

- unmould the plate,

- locating on the rear face of the plate some light-emitting points located so that they are configured to illuminate the rear end of the fiber optic elements so that said lighting is transmitted to the front end of the fiber optic elements.

- the plurality of light emitters (5) located on the rear face of the plate (1) and configured to illuminate the rear end of the fiber optic elements (2) so that said lighting is transmitted to the front end of the fiber optic elements (2).

In the example of embodiment shown in the figures, the fiber optic elements (2) are located perpendicular to the front and rear faces of the plate (1).

More specifically, said fiber optic elements (2) are evenly distributed over the surface of the plate (1), for example, the plates (1) may comprise an array of 20 x 20 fiber optic elements (2).

In an exemplary embodiment, the fiber optic elements (2) comprise a minimum diameter of 130 micrometers.

As mentioned above, the plate (1) is made of plaster or plaster or a conglomerating construction material and may comprise artificial fibers or natural fibers incorporated in the material kneading process in a percentage between 0.5-2%. in reference to the binder mass.

In an example of embodiment, the prefabricated object of the invention may comprise a reinforcing mesh (3) of synthetic or natural fiber embedded in the plate (1) and arranged parallel to its front and rear faces. Said reinforcing mesh (3) is placed parallel to the faces of the plate (1) and in a central position between them. The minimum thickness of the reinforcing mesh (3) is equal to or greater than 1 mm.

The reflective grid (4) is located adjacent to the rear face of the plate (1) and comprises a set of cavities open towards said rear face of the plate (1). The light emitters (5) are placed in said cavities to reflect the light towards the rear ends of the fiber optic elements (2).

The reflective grid (4) is made of a polished material and comprises quadrangular cavities where at least the rear end of an optical fiber element (2) and a light emitter (5) are located in each cavity.

The light emitters (5) are of the LED type, for example, an LED-type strip.

As discussed above, the manufacturing method comprises the following steps:

- providing a mold of at least one plate (1) having a front face and a rear face,

- location on the surface of the mold of a plurality of fiber optic elements (2) that have a front end and a rear end so that they will cross the thickness of the plate (1),

- pouring a mass from the plate (1) into the mould,

- hardening of the plate mass (1),

- demoulding of the plate (1),

- location on the rear face of the plate (1) of some light-emitting points (5) located so that they are configured for lighting the rear end of the fiber optic elements (2) so that said lighting is transmitted to the front end of the fiber optic elements (2).

In an embodiment, the length of the fiber optic elements (2) is greater than the thickness of the plate (1) so that after demolding the plate (1) the length of the fiber elements is cut lens (2) protruding from the front and rear faces of the plate (1).

The method may also comprise a step prior to the location on the surface of the mold of a plurality of fiber optic elements (2), where said step comprises the location in the mold of the reinforcing mesh (3) of synthetic or natural fiber intended to be located parallel to the front and rear faces of the plate (1).

Next, a detailed embodiment of the method of elaboration of the translucent modular construction prefabricated for transmission of light and information in designed interiors is described. Said manufacturing method, also object of the present invention, comprises the following steps:

a) Placement of the reinforcing mesh (3), for example, in fiberglass or similar, with a minimum thickness of one millimeter in the intermediate region that includes the formwork, which can be metallic or other similar material that facilitates its extraction. once the precast has hardened. It should be noted that, for correct stripping, it is convenient to impregnate the surface of the mold in contact with the prefabricated part with oil or similar. b) Next, the plurality of fiber optic elements (2) are placed, for example, a fiber optic mesh with a fiber length greater than the thickness of the mold of at least one centimeter for each of the surface faces of the mold. prefabricated. Said matrix can have variable dimensions, and for the exemplary case of the present invention, an arrangement of 20x20 points has been represented, with a minimum diameter of the fibers of 130 microns.

c) Preparation of the plaster mixture according to the chosen dosage and, for example, according to the UNE EN 13279-2:2014 standard.

In a preferred embodiment of the method object of the invention, the kneading process in turn comprises the following steps described:

c.1) the mixture is stirred for a time between 15 to 30 seconds, describing movements in the form of eight;

c.2) the mixture is allowed to stand for at least 30 seconds, and not more than one minute;

c.3) the mixture is stirred for a time between 15 to 30 seconds, describing movements in the shape of an eight, until a homogeneous paste is obtained and before it begins to harden.

The method object of the invention may also comprise a stage prior to step b), in which natural or synthetic fibers dispersed in the water are incorporated in a percentage between 0.5 and 2% with respect to the weight of the conglomerating material.

d) Pouring and vibrating of the mixture prepared inside the formwork for the realization of the plate (1).

e) Once the mixture has hardened, unmold the prefabricated plate (1) and prepare the surfaces. Said preparation comprises a stage of cutting and cleaning the optical fiber elements (2), so that this cut is orthogonal to the axis of the fiber and without harming the transmission of light, leaving the fibers fully embedded in the thickness of the prefabricated . f) Subsequently, the reflective grid (4) is placed embedded in the prefabricated plaster by means of a tongue-and-groove system. Said reflective grid (4), preferably metallic, must be in contact with the surface face that is going to be located in the non-visible part of the precast, that is, attached to the rear face of the plate (1).

g) Finally, we proceed to the location of the light emitters (5) in the form of LED strips, located in the central region of each square cavity that makes up the reflective grid (4) above each point of the fiber optic matrix embedded in plaster. Once fixed in their final position, these LED luminaires are connected to the microcontroller system for their correct start-up.

The application most directly related to the backlit modular prefab developed in the present invention is to decoratively illuminate the interior of residential rooms, tertiary buildings and commercial premises, as well as to transmit information that can be displayed on the surface of the rooms. prefabricated plates or panels from inside the different rooms.

These prefabricated elements can be used due to their multiple execution possibilities, both as false ceilings or ceilings in rooms, as well as for the execution of interior cladding and partition walls that wish to be illuminated with decorative motifs or, for example, for signaling exits from emergency or information display.

The dimensions of the prefabricated blocks can be indicative, but not limiting, of 600x600 mm2 of surface and variable thickness, although never less than 40 mm if they are not flat. Although the prefabricated design manages to support the weight of the plaster without problems, even more so if it fits with the reinforcement of internal fiberglass mesh, it is not advisable to exceed the dimensions of 1000 mm wide and 2400 mm high to facilitate the work of the operator and avoid possible breakage caused by possible buckling efforts that may arise in the pieces. In addition, the larger the size of the panel, the greater the content of LED strips and fiber optics, with which the processor must have more capacity to control possible decorative lighting or the transmission of information through the surface of the panel. prefabricated.

In the case of rectangular pieces, it is advisable to reinforce the plaster matrix by using synthetic fibers (eg fiberglass, basalt or polypropylene) or vegetable fibers (eg wood fiber or hemp) for resistance to bending. of the mixture, avoiding at all times that these fibers interfere with the ends of the optical fiber that crosses the thickness of the material, which must present a clean cut and without obstacles. In turn, it is possible to incorporate metallic aluminum devices on the back of the false ceiling plate, which allow it to be placed on the anchoring elements. These elements can be incorporated during the setting process of the plaster material described for its manufacture.
