離が起こりやすいという問題があった。[Background Art] Conventionally, multi-layer construction boards have been manufactured using Maruami Nisho-zukuri Iso in the following manner. That is, the cement slurry is filtered through a circular mesh cylinder, transferred to an endless felt, then adjusted to a predetermined moisture content using a suction belt to obtain a single-layer original sheet, and this single-layer original sheet is then passed through a making roll until it reaches a specified thickness. It is manufactured by winding it up while pressing it, then canting it and curing it. However, when the architectural boards manufactured in this manner are used as exterior materials, there is a problem that the moisture within the boards freezes, making peeling between the eyebrows apt to occur, especially in cold regions.

Obtain an original sheet 5, press this single layer original sheet 5 onto a making roll 6 until it reaches a predetermined thickness, and then roll it up, and then cut it to obtain a multilayer original sheet 7,
In the method for manufacturing architectural boards, which includes curing, a brush 8 is applied to at least one side of the single-layer paper base plate 5 before or during winding while pressing the single-layer paper base plate 5 onto a making roll 6. This structure is characterized by forming a rough surface by applying a rough surface, and this structure achieves the above object. That is, by applying the brush 8 to the single-layer paper-made original plate 5 to form a rough surface, the adhesion area between the single-layer paper-made original plates 5 is increased, and the adhesion between the eyebrows can be improved.

いでノーキングロール６によりプレスしながら巻取る。The present invention will now be described with reference to the accompanying drawings. The cement slurry 1 in the present invention refers to fl! The composition differs depending on the type of construction board; for example, asbestos cement board contains 40% by weight of ordinary Portland cement, 25m1% of blast furnace slag, 20% by weight of barley, 10% by weight of asbestos, 5% by weight of fiber, etc. Add admixtures as desired, add water and mix until the concentration is 5-15% by weight! %t. ! ! Other construction boards include mortar board, cement tile, asbestos slate, wood wool cement board, asbestos cement perlite board, pulp cement board,
This concludes by listing cement products such as decorative stone-aged cement boards. This cement slurry 1 is stored in a slurry tank 9, and is filtered through three immersed circular mesh cylinders 2. The slurry plate 10 thus obtained is transferred to the endless felt 3. The filtrate 11 is reused. Next, the slurry plate 10 is dehydrated by a suction belt 4 to a predetermined moisture content to obtain a single-layer papermaking original plate 5. In this embodiment, before winding up the single-layer paper sheet 5 with a making roll 6, one side is brushed with a brush 8, which is a roll brush, to form a rough surface, and then rolled up while being pressed with a no-making roll 6.

る。At this time, the other surface of the single-layer papermaking original plate 5 is also brushed using the brush 8, which is another roll brush, to form a rough surface. In this way, the double-sided roughened single-layer paper blank 5 is wound around the no-king roll 6 while being pressed by the press roll 12.
