Abstract

The invention relates to a building system resulting in a building element comprised of a building board made, for example, from a plaster or paper mixture and intended to be fixed to studs when making walls. The building board is of a small building board size, such as 900 x 1200 mm, and partly provided with a double groove and tongue joint or entirely provided with a double groove and tongue joint, being glued to the stud and at the groove and tongue joint, handled by a high-lift handtruck, nailed using dyckert nails.

Description

Building system
This invention relates to a novel building system resulting in a building element comprised of a building board made, for example, from a plaster or paper mixture and intended to be fixed to studs when making walls. The board can be a particle board, wood fiberboard, plywood board, veneer board, among other things. The board can even be a plaster-based board including paper, wood, glass fiber, among other things, or a cement-based board with different reinforcements of fiber, such as glass fiber or the like.
Today, plasterboard with a sheet of paper on each side is by far the most popular building material (paper-plaster-paper). The boards are long because they must extend from floor to ceiling. This makes the boards difficult to handle (load injuries), always involving the risk of breaking if handled in the wrong way. The boards are screwed to the studs using so-called drywall screws penetrating quite deep into the surface of the board. Besides, plasterboards have lowered edges for the purpose of obtaining a stable stay-in-place spackled surface. The joints are provided with anti- crack joint strips. The tightened screws require quite a lot of spackle and, at the same time, fracture parts of the plaster body of the board. Long-term wall handling and installing easily causes back and shoulder injuries.
This invention relates to an entirely new logistics, assembly and building system having great benefits compared to the above-described known technique. The invention is characterized by a combination of materials and in that the building boards are advantageous in terms of ergonomics, board size, shelf life, installation time, spackling time and spackling material, gluing to a stud frame and using a double tongue and groove joint; require less installation tools, reduce load injuries, increase shear strength and reduce cracking. For example, 900 x 1200 mm and with a double groove and tongue joint. The board can be partly or entirely provided with a groove and tongue joint on two sides or four sides. The boards are joined together and to the studs with glue on all contact faces and with dyckert nails/screws and/or staples. The boards have no front or back side. The dependent claims describe different embodiments of the invention. The novel inventive product, a wall system which concerns wall boards and which can be treated with a "WSJ" medium will introduce an entirely new technique of in- stalling building structures, such as walls. The WSJ method allows the boards and the wood stud frame to attain a moisture ratio certification with a documented critical moisture ratio (mold resistant). The structure and the wood studs may attain a moisture ratio certification as well as a moisture ratio certification and fire protec- tion class A2, respectively. "WSJ" treated panels are not necessary in certain definitely dry premises but the WSJ method is always recommended if there is any risk of fire.
When small board sizes, such as 900 x 1200 m, entirely provided with a double groove and tongue joint on four sides, or partly provided with a double groove and tongue joint, are used and when the boards are joined together as well as to the studs, the installation takes up to 1/3 less time. Besides, the boards are much lighter to handle than long boards extending from floor to ceiling. The joining is carried out using glue which makes the structure very stable.
Further, dyckert nail/screw/staple models only involving a small amount of spack- ling work are used. The joints between the boards are fairly smooth immediately after the installation and do not require much grinding and spackling. Thanks to the invention, 80 % less spackling time is needed.
When even the studs are treated with the "WSJ" medium and attain a moisture ratio certification and fire protection class A2, they can be fixed to concrete walls, floors and ceilings without any risk of mold damage or fire spreading. The invention also allows wall thicknesses above the known standard to be manufactured.
Transport and handling The novel small boards with a double groove and tongue joint provide not only a simpler installation technique but also a new receiving system at the work site. The material is taken to the work site when the external walls and the roof are in place, the work site is dry and warm, there are no plasterboard bundles blocking the installation of the frame. At the work site, one person can handle 0 to 80 m2 in no time without lifting and thereby straining his back, which reduces load injuries and is very time saving. At the work site, the boards are handled by a high-lift handtruck which, at the same time, is the worker's work table with infinitely variable working height adjustment. The double groove and tongue joint results in less board waste. This is both environmentally and economically favorable.
Figure 1 shows an example of a double groove and tongue joint; and
Figure 2 shows a cutter for the milling machine.
It is also possible to cut the boards using a special-made milling machine which, while cutting, also creates a double groove and tongue joint in the edges of the both boards that are being cut.
The invention is not restricted to the above-described example but may vary within the scope of the accompanying claims. The studs do not have to be of wood but they may as well be plate structures know per se. The building boards can alternatively be glass fiber, wood fiber or cement based boards ;

2. A building element as defined in claim 1, characterized in that the building board is entirely provided with a groove and tongue joint on four sides or partly provided with a double groove and tongue joint.
3. A building element as defined in claim 1 or 2, characterized in that the building boards are always joined together and to the studs with glue applied to both the stud and the double groove and tongue joint as wells with dyckert nail/screws and/or staples.
4. A building element as defined in claim 1, 2 or 3 characterized in that the stud is a wood stud/composite wood stud, alternatively a steel stud.
5. A building element as defined in any of the preceding claims, characterized in that the building board and the wood stud are treated with a "WSJ-Sanitation Ab" anti-mold and anti-flame agent, such as the one with the trademark "Vital Protect", where the structure requires the above-mentioned treatment, thereby attaining fire protection class A2.
6. A tool for cutting a building element as defined in claims 1 to 5 and for creating, at the same time, a double groove and tongue in the edges of the boards that are being cut, characterized in that the tool is a milling machine with one or two cutters that cut a double groove and tongue joint in the edges of the boards that are being cut.
