Description
【発明の詳細な説明】 この発明社天井用石こうボードに関する。[Detailed description of the invention] This invention relates to a gypsum board for ceilings.
石こうボードは石こうを芯材にして表面を厚紙で榎って
なる不燃性の建築材料であり、主として建築物における
壁や天井等の内装材として広く使用されている。Gypsum board is a noncombustible building material made of gypsum as the core material and the surface covered with cardboard, and is widely used mainly as an interior material for walls and ceilings in buildings.
しかしながら石こうボードの施工において鉱。However, in the construction of gypsum board.

b) Most of the methods use fixing material (8) such as nails, screws, staples, etc. to the base material (end) such as wood or steel, so the fixing material (8) is plaster. board(
1m) (lb) It is undesirable in terms of design as it protrudes from the surface, and there is a weak point in terms of fire safety at the butted part (joint) (41).

材である石ζう社非常にもろく、欠りやすい九め現状で
は使用に耐えず実現するに至ってない。For this reason, a promising method is to process the end sides of the gypsum board to create a real shape, as seen in some rock wool boards, but as is well known, 1. The material is extremely brittle and easily damaged.Currently, it cannot withstand use and has not yet been realized.
この発明社これらの欠点を解消し、釘頭の見えなｈ火葬

する。This invention aims to eliminate these drawbacks, to obtain a ceiling gypsum board that can be used to construct a cremation system with no visible nail heads, and that has dramatically improved fire protection performance. A concave groove and a part of a convex protrusion are respectively formed on the side surface of the other end, and the concave groove and convex protrusion are coated or impregnated with a synthetic resin. shall be.
以下、その詳細を図面に基いで説明する。The details will be explained below based on the drawings.

して構成される。FIG. 2 is a perspective view schematically showing the ceiling gypsum board of the present invention, and FIG. 5 is a schematic sectional view showing an example of its installation. In FIG. 2, the ceiling gypsum board of the present invention (
6) consists of a gypsum core material (7) and cardboard (8) covering its surface, and has a concave groove (2) on one end side and a convex protrusion αp that fits with this on the other end side. After processing, the concave groove shaft and the convex protrusion (1B (hereinafter referred to as the real part)) are coated or impregnated with synthetic resin (9) (shaded area in the figure).

きる。This actual part is shown in Figure 2 on the ceiling gypsum board (
6) Although it is formed on the side surface of the longitudinal end, it can also be formed in the short side direction, which is limited to one shown, or in both long and short directions.
ここで合成樹脂としては未反応プレポリマーを有する溶
解液若しくはエマルジョン型合成樹脂が好適である。Here, the synthetic resin is preferably a solution or emulsion type synthetic resin containing an unreacted prepolymer.

て浸透性を良くした溶解液を用するとよい。As the unreacted prepolymer, an isocyanate prepolymer containing unreacted iso7anate and having a viscosity of 100 to 200 cps/25υ is diluted with a solvent such as methyl ethyl keto7゜quidylol or trol to reduce the viscosity to 20 cps.
/2 st7. It is preferable to use a dissolving solution with improved permeability at 5 cps/25υ or less.

ロールコータ−若しくは刷毛塗抄すると良い。Apply this solution to the actual part of the plasterboard using a roll coater.
When it is applied with a spray etc. for 50 to 12,097 m and impregnated, it reacts with moisture in the air and the moisture in the gypsum core material and turns into a resin. As above, it is sufficient to apply 50 to 12,097 m'' on the actual part of the gypsum board, but since the viscosity is higher than that of the incyanate prepolymer solution,
It is best to use a roll coater or brush coating.

の表面に出ない強固な天井面を構成することができる。The actual part of the gypsum board (6) reinforced by applying or impregnating synthetic resin in this way is compared with the untreated one.
The shear strength is more than 5 times that of isocyanate prepolymer, and about 5 times that of emulsion-type synthetic resin. It adheres to the base material (2) such as wood or steel,
By sequentially aligning the concave groove αOK and the convex protrusion α, the nail head can be easily attached to the gypsum board (6).
It is possible to construct a strong ceiling surface that does not appear on the surface of the ceiling.

が飛躍的に向上した。Regarding fire resistance, a test specimen was made with the ceiling surface shown in Figure 1 and TAS diagram, and the flame of a city gas parlor was applied directly to the joints to measure the surface temperature of the base material (2) made of wood. As a result of measurements, the conventional ceiling surface shown in Figure 1 burned 5,628 pieces (of the base material) after about 6 minutes, while the ceiling surface using the gypsum board of the present invention, shown in Figure 3, burned 10.
Even after several minutes had passed, the base material (2) remained at about 26,017, indicating a dramatic improvement in fire protection performance.
