Description

[Detailed description of the invention] This invention is suitable for constructing ceilings etc. by incorporating adjacent gypsum boards into each other.It has good workability and has a progressively new feel in which colored or patterned iron plates are widely exposed at the joints. The present invention relates to a gypsum board that can express the above-mentioned characteristics and has significantly improved construction strength and fire resistance.

The present invention will be explained below with reference to illustrated embodiments.

FIG. 1 is a cross-sectional explanatory diagram of the gypsum board of the present invention.
The plaster parts JA and B are both wooden crosspieces glued parallel to each other on the upper surface near the long side of the plaster board.

A is a wooden crosspiece that is glued to the upper outer side of one end surface 2 of the plaster part 1, and the upper outer side of the projecting part is cut out in a rectangular shape.

The vertical side of the notch is 3, the horizontal side is 4, and the top edge of the wooden frame is 5.

One guideline is for surface 3 to be at a position approximately ÷ of the overhang.

Furthermore, the bottom 6 of the wooden crosspiece A is cut out in a concave shape and horizontally parallel to the side edge in the length direction slightly inside the end surface of the upper surface of the plaster part 1 and slightly inside the foremost edge 5 of the wooden crosspiece.

This concave notch is defined as 8, and a metal plate 9 that can be tightly inserted is inserted into the notch 8 and bonded to the wooden frame with an adhesive 10.

Such a wooden crosspiece A is adhered to the plaster part of the board with an adhesive 11.

This metal plate improves construction strength and creates a wide joint between adjacent boards, and can also be used in colored iron plates, printed decorative iron plates, etc.

Furthermore, this iron plate 9 is slightly interlocked with and straddles the upper surface of the plaster part of the end face of the plaster part of the adjacent board (the third
(see figure).

Regarding the wooden frame B, it has a shape that fits into the outside of the wooden frame A, and has a rectangular cross section with a cutout on the lower outside, the vertical plane of the cutout is 12, the horizontal plane is 13, and the outermost surface is 14.
shall be.

The most extreme surface 14 of this wooden crosspiece B is positioned substantially inside the end surface of the plaster part of the board and is bonded onto the plaster 1 with an adhesive 15.

The wooden beams of adjacent boards are closely fitted horizontally and their surfaces are aligned on the same plane, and the state in which this gypsum board is installed, for example, on a ceiling, can be seen from the cross-sectional explanatory diagram in Figure 3. Decorative iron plate 9 inserted and glued into the concave notch at the bottom of wooden frame A
The gypsum sections 1 and 1' of the adjacent gypsum boards are suspended and straddled by the upper portions of both end faces of each of the gypsum sections 1 and 1', forming a beautiful bottom joint.

This iron plate has the remarkable effect of greatly increasing fire resistance and improving strength.

Even if the thickness of the iron plate 9 is normally about 0.27 to 0.3 mm, the effect is sufficient.

Regarding the construction method of the gypsum board of the present invention, first, the gypsum board is fixed to the edge C of the ceiling or the like with nails or screws D from the bottom of the gypsum board wooden frame A diagonally upward.

That is, FIG. 2 is a cross-sectional view of how nailing is done.

Next, by fitting the adjacent plasterboard (all the numbers of the plasterboard parts are dashed) from the side, the state shown in the cross-sectional explanatory diagram of the joint of the adjacent plasterboards as shown in Figure 3 is obtained. becomes.

The notches of the wooden crosspieces to be glued to both side edges of the plasterboard may be provided so that they fit together so that the surfaces are on the same plane.
It may have a shape as shown in the cross-sectional explanatory diagrams of FIGS.

In addition, it is possible that the surfaces of the wooden beams are not on the same plane, but this poses problems in terms of strength and workability.
Furthermore, the surface of the board becomes uneven and is not suitable for packaging.

As mentioned above, when the present invention is constructed, the joints become metal plates and all exposed surfaces are made of fire-resistant materials, which not only exhibits excellent performance in terms of fire prevention and fire resistance, but also
The metal plates used for joints can incorporate beautiful designs such as colored iron plates and printed decorative iron plates, which have a great decorative effect.

As mentioned above, the main point of the present invention is to provide a gypsum board in which wooden crosspieces are glued parallel to the upper surface near the edges of both long sides of the gypsum board, and the wooden crosspieces are attached to one long side of the gypsum board. When connecting wooden beams that extend outward and are provided on other long sides, a cut is made so that when they are adjacent, the surfaces of the long sides are kept on the same plane and fit together, and the above-mentioned outside Place a metal plate, such as a colored iron plate or printed decorative iron plate, on the bottom of the overhanging wooden frame at the joint of the adjacent board in advance so that it is suspended by the upper edge of the plaster part of both boards so that it straddles the joint. The cut-out portion is inserted and glued, and the metal plate is configured so as to be exposed at the joint portion after construction.
