を与えやすかった。2. Description of the Related Art In large buildings such as gymnasiums, halls, factories, and the like, ceiling materials are usually not provided, and construction is often performed with the back surface of a field base plate made of wood chip cement plate or the like exposed. However, if there is no ceiling material, the sound will reverberate indoors, or the outside temperature will be transmitted directly to the room because sufficient insulation cannot be obtained, and the environment will be hot and cold in summer and bad in winter. In addition, when looked up, the appearance was poor, and it was easy for the user to feel uncomfortable.

上での作業となるので、施工性が良くなかった。[0003] In order to solve these problems, a composite board having a rock wool sound-absorbing plate adhered to the back surface of a wood chip cement board or the like is sometimes used. However, the wood chip cement board is heavy and rigid. Poor nailing and workability. In particular, the work was performed on the roof, so the workability was not good.

ことを特徴とする。The refractory base plate of the present invention comprises:
A front and back layer (1) having a specific gravity of not less than 0.9 mainly composed of mineral fibers, an inorganic powder and a binder, and a specific gravity of not less than 0.4 and not more than 0.9 mainly containing an inorganic foam and a binder. A rock wool sound-absorbing plate (3) is adhered to one surface of a three-layered inorganic plate having an overall specific gravity of 0.6 or more and 0.9 or less comprising an intermediate layer (2).

野地板とすることができる。According to this, the weight can be reduced by the middle layer using the inorganic foam. The front and back layers made of mineral fibers and inorganic powders provide the front and back surfaces that are easily elastically deformed despite the relatively high density of specific gravity of 0.9 or more due to the entanglement of the fibers. Hammering,
The nail holding force can be improved, and construction on a curved surface portion is also possible. As a result, it is possible to obtain a field base plate that is lightweight, high-strength and excellent in heat insulation as a whole.
【0007】全体比重が0.6以上0.9以下であるの
で、釘打ち性を高めている。無機質板の釘打ち性は比重
に大きく影響され、0.9を越えると釘打ちしにくく、
特に板端部に釘打ちすると基材クラックが生じやすい。
また、0.6未満であると釘頭貫通抵抗力、釘側面抵抗
力等の釘保持力の低下が激しく、応力がかかった際に釘
打ち部で破壊が発生しやすい。Since the overall specific gravity is 0.6 or more and 0.9 or less, nailing performance is improved. The nailing properties of the inorganic plate are greatly affected by the specific gravity.
In particular, when the nail is nailed at the edge of the plate, the base material crack is easily generated.
If it is less than 0.6, the nail holding force such as the nail head penetration resistance and the nail side surface resistance is greatly reduced, and when a stress is applied, the nail is likely to break at the nailed portion.

工性,断熱性に優れた耐火野地板となる。The surfaces of both the inorganic plate and the rock wool sound-absorbing plate are substantially smooth, and the peel strength can be prevented by increasing the adhesive strength. The rock wool sound-absorbing plate itself is a material that is lightweight and has excellent fire resistance, heat insulation, sound absorption, and design properties. When combined with an inorganic plate, the rock wool sound-absorbing plate has further excellent strength, workability, and heat insulation. It becomes the main plate.

あることがわかる。The specific gravity of the embodiment and that of the comparative example are significantly different.
And the comparative example is 40 kg / sheet. For this reason, it can be seen that the embodiment is lighter by 30% or more with the same size and easy to handle.

容易であることがわかる。Regarding nailing, about 10 m from the edge of the plate
The nail was nailed at the position of m, and the appearance was judged. In the examples, nails could be easily driven, and no crack was observed on the plate. On the other hand, in the comparative example, nailing was difficult due to the rigidity of the plate, and cracks frequently occurred in the plate even when the nail was driven. It can be seen from the weight and the workability that the working example is easier to perform than the comparative example.
