【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、天井下地上に岩綿吸音板を設置してなる
天井構造に関するものである。[Detailed description of the invention] [Industrial application field] The invention relates to a ceiling structure in which a rock wool sound absorbing plate is installed on a ceiling base.
従来の岩綿吸音板は、第３図に示すように、曲面の天
井下地になじむように上面に10〜20ミリのピッチでスリ
ット30を加工していた。As shown in FIG. 3, a conventional rock wool sound-absorbing plate has slits 30 formed on the upper surface thereof at a pitch of 10 to 20 mm so as to conform to a curved ceiling foundation.
しかしながら、上記構造ではスリット周辺の強度が低
く、天井下地の曲率が大きい場合（曲率半径900ミリ以
下）、岩綿吸音板が折れる危険性があった。また、岩綿
吸音板を下地になじませる時、取扱い時にもスリット周
辺より折れてしまうことがあった。However, in the above structure, when the strength around the slit is low and the curvature of the ceiling foundation is large (the radius of curvature is 900 mm or less), there is a risk that the rock wool sound absorbing plate is broken. Also, when the rock wool sound-absorbing plate is blended into the base, it sometimes breaks from around the slit during handling.
したがって、この考案の目的は、曲率の大きな天井下
地にも容易に対処して、折れることなくなじんだ状態で
岩綿吸音板を施工できる天井構造を提供することであ
る。Therefore, an object of the present invention is to provide a ceiling structure that can easily cope with a ceiling foundation having a large curvature and can install a rock wool sound-absorbing plate in a conformed state without breaking.

音性能に加えて遮音シートの遮音性能が付加される。According to the configuration of the present invention, since the sound insulation sheet is attached to the surface on which the slit has been processed, it is possible to reinforce the periphery of the slit having low strength and to bend even the ceiling base having a large curvature. Also, the lower surface of the rock wool sound-absorbing plate body is formed in a flat shape and securely adhered to the upper surface of the ceiling foundation, and the lower surface of the rock wool sound-absorbing plate body is flat, so the slit is It can be formed as deep as near the lower surface, and can easily cope with the rock wool sound-absorbing sound-absorbing plate even if the curvature of the upward convex curve of the ceiling base is large. Further, in addition to the sound absorbing performance of the rock wool sound absorbing plate main body, the sound insulating performance of the sound insulating sheet is added.

にしたものである。Reference numeral 10 denotes a rock wool sound absorbing plate, which includes a rock wool sound absorbing plate main body 1 and a sound insulating sheet 2. The lower surface 1a of the rock wool sound absorbing plate main body 1 is a surface provided along the ceiling foundation 4, and the upper surface 1b is provided with slits 3 at predetermined intervals. The sound insulation sheet 2 is a sheet having a sound insulation property in which a granular material of a high specific gravity substance is dispersed in a vinyl chloride sheet, and has a specific gravity of about 1.0 to 2.0 (for example, VK009 manufactured by Matsushita Electric Works, Ltd.). The rock wool sound-absorbing plate 10 is formed by sticking the sound insulating sheet 2 to the upper surface 1b of the rock wool sound-absorbing plate main body 1 to be integrated.

きる。Fig. 2 shows a rock wool sound-absorbing plate on the ceiling
An example where No. 10 was constructed is shown. That is, the rock wool sound-absorbing plate 10 is bent along the upper surface 4a of the ceiling base 4 that is upwardly convex and conformed. In this case, since the periphery of the slit 3 having low strength is reinforced by the sound insulation sheet 2, the rock wool sound absorbing plate 10 does not break even if the curvature of the ceiling foundation 4 is large. Further, in addition to the sound absorbing performance of the rock wool sound absorbing plate main body 1, the sound insulating performance of the sound insulating sheet 2 is added, and the sound insulation is improved. Further, since the sound insulating sheet 2 is attached, even if an external force is carelessly applied to the rock wool sound absorbing plate 10 at the time of handling, it is hard to break. Also, the lower surface of the rock wool sound absorbing plate body 1
1a is formed in a flat shape and is securely attached to the upper surface of the ceiling base 4. Furthermore, since the lower surface 1a of the rock wool sound-absorbing plate main body 1 is planar, the slit 3 can be formed deeply near the lower surface 1a of the rock wool sound-absorbing plate main body 1, and the curvature of the upward convex curve of the ceiling foundation 4 is reduced. Even if it is large, the rock wool sound-absorbing plate 10 can be easily installed alongside.

加され、防音性が向上する。According to the configuration of the present invention, since the sound insulation sheet is attached to the surface on which the slit has been processed, it is possible to reinforce the periphery of the slit having low strength and to bend even the ceiling base having a large curvature. Further, by attaching the sound insulating sheet, there is an advantage that the rock wool sound absorbing plate is unlikely to be broken even if an external force is carelessly applied during handling. In addition, the lower surface of the rock wool sound absorbing plate body is formed in a flat shape, is securely adhered to the upper surface of the ceiling base, and the lower surface of the rock wool sound absorbing plate body is flat,
The slit can be formed as deep as possible near the lower surface of the rock wool sound absorbing plate main body, so that the rock wool sound absorbing plate can be provided along the ceiling base plate easily even if the curvature of the upward convex curve is large. Furthermore, in addition to the sound absorbing performance of the rock wool sound absorbing plate main body, the sound insulating performance of the sound insulating sheet is added, and the sound insulation is improved.
