Description

Building board system

Technical field

The invention relates to a Build board arrangement for implementing, for example, furniture and/or parts of buildings and/or vehicles and/or ships and/or other products or structures. For example, the furniture may be furniture used in offices, apartments, hospitals, schools, production lines, assembly lines, and/or restaurants, and/or short-term furniture implementations, for example, at trade fair. Said parts of the buildings may be, for example, walls, ceilings, and/or floors.

Prior art

In the prior art, Build board arrangements include boards made of, for example, gypsum, plywood, particle board and/or wood, which may be coated with, for example, various laminate, vinyl, metal, paper, paperboard or spray coatings. Said combinations of construction material and coating material are installed to provide the desired structure. Generally in prior art, electrical devices and furniture are installed at the desired location in the furniture or objects in the operating environment with traditional screw connections, as a surface-mounted or flush-mounted housings. Cable installations complicate convertibility, i.e. design freedom that adds value in electrical design.

It is almost impossible to embed electrical wires in a panel-like build board, so the cables remain visible. The cables are visually messy and make cleaning and interior design difficult. The installation of electrical furniture and devices on the edge of the build board is challenging with traditional methods due to the installation of the cable and the space required by the connecting wires.

In the traditional electrical installation method, where the electrical device or furniture is flush-mounted, the structure of the installation accessories required does not take into account sound insulation and/or air leakage. Therefore, applications such as wall or ceiling structures have to be retrofitted .

The state-of-the-art space elements are similar in structure to a conventional partition wall consisting of, for example, a frame made of wood or sheet metal, on the surface of which said panels are fixedly mounted and the space between the frames is filled with, for example, insulation wool or other insulating material. Disadvantages of said structure are, for example, the sound bridges caused by the solid and hard frame material between the surface boards. Another disadvantage is the lack of weak coupling, which means a flexible coupling between said materials and/or a structure, wherein the sound-conducting materials are not in direct contact between the outer surfaces and which prevents sound from conducting along hard surfaces. One of the essential causes of a cold bridge is, for example, metal frames that conduct heat well.

Prior art technology does not know the perforation pattern advantageously arranged in the build board. If the conductor boards are holeless or nearly holeless boards, it can cause the following unfavorable characteristics: 1 ) an increase in the total mass of the overall structure, which, among other things, complicates the installation work and increases the manufacturing costs of the build board, 2) an increase in the capacitance values between the conductor boards, 3) complicates the work of attaching the build boards to the frame structure, because openings must be processed to the conductor boards, for example by drilling or already in the manufacturing process, so that the fastening means of the build boards do not hit the conductor boards and thus cause electrical contact with said fastening means, and the openings created in the conductor boards, for example by drilling, increase manufacturing and installation costs, among other things.

Prior art technology does not know a method for installing and/or attaching the boards of a build board arrangement to a frame made of metal thin board, which can be arranged, for example, on a wall, ceiling or floor. The problem can be, for example, electricity-conducting screws or other fastening devices hitting the said electricity-conducting frame structure, in which case electricity can be unintentionally conducted into the frame structure. If, for example, two screws or other electrically conductive fastening means attached to different conductor boards hit the same electrically conductive frame structure, the result is, for example, a short circuit or other undesirable connection of two different conductors.

Prior art technology does not know a method for connecting the power supply cable to the structure board arrangement from any direction relative to the structure board. The problem with the mentioned method is that connecting it is challenging, if the aesthetics are to be preserved in such a way that, for example, there is no junction box or other technically equivalent solution left on the visible surfaces. In a generally known technique, the power supply cable is brought to the inside or surface of a desired wall or ceiling, for example, from where it is connected to a socket or other desired location or device.

Commonly known technology does not know a method for protecting the connection components of build boards with a grounding board. If the connecting component is installed at the junction of two build boards behind, for example, a skirting board or a ceiling board, and the mentioned are, for example, wood that can be pierced with, for example, a nail or a screw, hitting the wiring part of the connecting component causes electricity to be conducted to the said nail or screw, which can result in an electric shock to a person or animal.

Publication FI20145752 describes a system consisting of modular furniture elements that can be modified and has an integrated electrical network. Said publication focuses on molded furniture parts, which are laborious and complicated to manufacture. In the case of electrically conductive structures, said publication focuses on structures other than sheet metal, which limit the possibility of free connection of electrical devices to different surfaces of the structure. Said publication does not address the need for an electrified build board to operate independently without other build boards attached thereto. Said publication does not take a position on a layered structure, which is a preferred embodiment for furniture and build board. This publication does not take a position and does not focus on solving the problem of technical challenges relevant to sound insulation and thermal insulation, for example. Said publication does not take a position on the installation/attaching of a build board to an external structure which is not part of it, which is, for example, a wooden frame structure.

Publication FI20165157 describes the connection of electrical device and furniture to the surface of a modular furniture part with electrically conductive attaching means, but does not focus and solve any technical installation problems with which the electrical coupling and mechanical connection between the build boards can be implemented in an electrically safe and installation- friendly manner, for example in the case where the attaching and connection components cannot be installed inside the build board during installation. Publication FI201665157 does not take a position on connecting an electrical device to the conductor layer. FI201665157 considers only connection to the modular furniture part. FI201665157 does not take a position on the order and electrical safety of the conductor plates and does not focus on solving electrical safety challenges.

Summary of the mvention

The object of the invention is a new type of build board arrangement. The build board arrangement is a layered board structure in which at least three conductor layers and insulating material layers are arranged between them, and the conductor layers comprise mutually identical perforations that reduce the capacitance between the conductor layers

The build board arrangement according to the invention can be used, for example, for the implementation of furniture and/or parts of buildings. Said furniture may be, for example, furniture used in offices, apartments, hospitals, schools, production lines, assembly lines, and/or restaurants, and/or short-term furniture implementations, for example at trade fairs, or modifiable interior designs. Said parts of the buildings may be, for example, furniture, walls, ceilings, and/or floors.

The advantage of the build board arrangement according to the invention is that due to its layered structure the electrical device can be freely installed in said system in places defined by its surface area. The advantage of the Build board arrangement according to the invention is that the electrical device can be electrically safely connected to said system due to the arrangement of the conductor layers according to the invention. Another advantage is that conventional objects, such as paintings, mounted on the surface of the Build board arrangement are attached, for example, with screws or nails, whereby said installation procedure according to the invention does not pose a risk of electric shock to its users. Another advantage is that the manufacturing and installation costs of a Build board arrangement can be lower than in the case where the build boards and/or elements are manufactured by traditional methods, when the cost comparison takes into account the electrical installation work as well as the accessories. Another advantage is that fixed cable installations can be eliminated, for example, from installations of convertible furniture and/or various structures, which makes it possible to implement a flexible operating model without disturbing fixed cable installations. Another advantage is that a conventional plate wall with, for example, a frame, insulation, surface boards and fixed cable installations can be replaced by a space element system according to the invention. Another advantage is that a conventional build board, such as gypsum board, can be replaced by a build board arrangement according to the invention. Another advantage is that the build board arrangement and the space element system can be implemented according to the requirements of the structures, which are, for example, sound insulation, fire insulation, moisture insulation and the transmission of wireless data transmission. One advantage is also that the build board arrangement according to the invention reduces the increase of the capacitance value between the conductor boards. One advantage is also that in the build board arrangement according to the invention, attaching the build boards to the frame structure is not laborious, because there is no need to separately create holes in the build boards, for example by drilling, so that the fastening means of the build boards do not hit the build boards and thus cause electrical contact with said fastening means. Another advantage is that when you don't have to create openings in the build boards separately, for example by drilling, manufacturing and installation costs are reduced. One advantage is also that thanks to the build board arrangement according to the invention, attaching and connecting electrical devices, such as sockets, is more free in terms of location

The various exemplary embodiments of the invention are characterized by what is set forth in the dependent claims.
