【考案の詳細な説明】
この考案は、鉄骨高層建築物に適用される耐火
遮音中空間仕切壁の改良に関するものである。[Detailed description of the invention] This invention relates to an improvement of a fireproof and sound-insulating internal space partition wall that is applied to steel-framed high-rise buildings.

湿式中空間仕切壁とがある。 Conventionally, the above-mentioned fireproof and sound-insulating hollow space partition walls have been constructed with lightweight steel studs inside and inorganic molded boards such as calcium silicate boards, gypsum boards, asbestos slates, and concrete blocks pasted on both sides. There is a wet-type hollow space partition wall that is composed of a coating layer of a kneaded material mainly composed of inorganic fibers and an inorganic binder, such as mortar, plaster, rock wool, and cement.
しかし、前記乾式・湿式の両中空間仕切壁は、

度としなければならない。 However, both the dry type and wet type hollow space partition walls,
Since both sides of the stud are formed of a single member, the sound insulation properties of each wall are significantly reduced due to the coincidence phenomenon and the resonance transmission phenomenon due to hollow walls, and the sound insulation properties of each wall meet the standards specified in the Building Standards Act. To obtain the performance of a wall sound insulation structure, a fairly large areal density must be achieved.

構造による中空間仕切壁を遮音規準に合格させる
ためには、60〜70Kg／m2以上の面密度にしたもの
が必要となる。 For example, for the dry partition wall shown in Figure 1,
When a calcium silicate plate with a thickness of 24 mm is used for the double wall, as shown in Fig. 2, there is a tendency for transmission loss to decrease due to coincidence around 2500 Hz. On the other hand, for the wet partition wall shown in Figure 3, if the double wall is sprayed with rock wool, cement, gypsum, and plaster mixed with water to form a coating layer of 30 mm thick, as shown in Figure 4. However, there is a tendency for transmission loss to decrease around 1000Hz due to the coincidence phenomenon. For this reason, in order for a conventional single-structure hollow space partition wall to pass sound insulation standards, it is required to have an areal density of 60 to 70 kg/m 2 or more.
この考案は、上記の問題を解決するためになさ
れたものであつて、基本的には、第５図に示すよ

形成した湿式間仕切壁４で形成したものである。 This invention was made in order to solve the above problem, and basically, as shown in Fig. 5, one wall constituting the hollow space partition wall was formed by dry coating without using a base material. It is formed of only the partition wall 3, and the other wall is formed of a wet partition wall 4 formed with a coating layer of a kneaded material mainly composed of inorganic fibers and an inorganic binder on the surface of a base material of wire mesh. .

る。 As mentioned above, the hollow space partition wall is the dry partition wall 3.
and a wet partition wall 4,
The difference in stiffness between drywall and wetwall shifts the frequency at which the coincidence phenomenon occurs and compensates for each other's reduction in transmission loss. Therefore, even if the areal density of the wall is reduced, it is easy to satisfy the sound insulation standards for the parting wall. Wet partition walls are formed with a coated layer of a kneaded material mainly composed of inorganic fibers and inorganic binders on the surface of a wire mesh base material. The kneaded material containing the inorganic binder as a main material strongly bites into the mesh of the wire mesh. That is, the initial adhesive strength of the coating layer to the wire mesh is improved. This greatly contributes to the fiber strength after construction. Furthermore, since wire mesh is used as the base material, the weight of the wall can be significantly reduced compared to a conventional structure in which, for example, gypsum board is used as the base material and the surface is plastered.

とが確認された。 As an example, the dry partition wall 3 is formed of a calcium silicate plate with a thickness of 24 mm, and the wet partition wall 4 is formed by coating on the surface of the base wire mesh 7, and the thickness is made by kneading rock wool, cement, gypsum, and plaster with water. 30mm
The transmission loss in the hollow space partition wall formed in the coating layer is shown in FIG. As seen in this graph, a hollow partition wall that combines dry and wet walls does not reduce transmission loss and has sound insulation properties that exceed the sound insulation standards for parting walls under the Building Standards Act. Admitted. At the same time, it was confirmed that according to the above configuration, the areal density was kept at about 45 to 50 kg/m 2 and, in combination with the underlying wire mesh, it was effective in further reducing the weight of the wall.

ければならない。 In addition, in this invention, the wall formed of the inorganic molded plate needs to be composed only of the inorganic molded plate without using a base material, and for example, it is necessary to form an additional coating layer on the surface of the inorganic molded plate. Structures such as this must be avoided because they result in a reduction in transmission loss.

する耐火遮音中空間仕切壁が容易に得られる。 As described above, according to this invention, in a hollow fireproof and sound insulating partition wall formed by forming wall materials on both sides of studs, one wall is formed by pasting only inorganic molded boards without using a base material. The other wall is made of a lightweight wall because the surface of the base wire mesh is formed of a coating layer made of a kneaded material mainly composed of inorganic fibers and an inorganic binder, and the coincidence phenomenon peculiar to hollow space partition walls, that is, both walls By suppressing the resonance phenomenon between the two, the sound insulation effect can be greatly improved. Therefore, according to this invention, a fireproof and sound-insulating internal space partition wall having a sound-insulating structure of a parting wall specified by the Building Standards Act can be easily obtained without increasing the areal density of the wall.
