本発明は断熱遮音型枠パネルに関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to thermal and acoustical formwork panels.
一般に、断熱材と型枠用パネルで構成した断熱
型枠パネルが知られている。そして、従来の断熱

状態となり、断熱性能に加えて遮音性能も優れた
型枠パネルの開発が望まれていた。 However, no matter how the above-mentioned insulation materials and formwork panels are combined, a resonance phenomenon will occur in any band between 500 and 4000Hz, reducing the sound insulation performance between each room of the building. , as shown in Figure 1, the sound B transmitted through the insulation form panel is louder than the sound A transmitted through the parting wall.
D-50, which is the first class apartment building indicated by the Architectural Institute of Japan.
In addition to the D-45 rating, which is the first grade for hotels, it was not possible to meet the requirements, and there was a desire to develop a formwork panel that had excellent sound insulation performance in addition to heat insulation performance.
本発明は上記要望に応えるためになされたもの

るにある。 The present invention was made in response to the above-mentioned demands, and its purpose is that the insulation performance is not inferior to conventional ones, that resonance at 1000 to 4000 Hz can be prevented, and that the sound insulation performance between each room is improved. It is an object of the present invention to provide a heat-insulating and sound-insulating formwork panel that not only has a low deformation, has good workability, has sufficient strength as an interior base material, and is less prone to internal condensation and is advantageous in terms of disaster prevention.
以下、本発明の一実施例について図面を参照し
ながら説明する。 An embodiment of the present invention will be described below with reference to the drawings.
第２図は、本発明の断熱遮音型枠パネルの基本
構成を示すものであつて、１はグラスウールを断

Ｂでは断熱層１の厚み方向ｂを向くことになる。 FIG. 2 shows the basic structure of the heat and sound insulating formwork panel of the present invention, in which 1 is a heat insulating layer using glass wool as a heat insulating material. The heat insulation layer 1
As shown in FIG. 3A, high-density glass wool with a density of 60 kg/m 3 or more, for example, commercially available pine-like glass wool material G with a density of 96 kg/m 3 is used as the heat insulating layer 1.
It is cut into lengths (for example, 50 mm) corresponding to the thickness dimension t of , and the cut surfaces g are aligned and joined together with an appropriate adhesive as shown in FIG. Therefore, in the state shown in FIG. 3A, the fiber direction of the glass wool is oriented in the direction of the arrow a, but in the state shown in FIG. 3B, it is oriented in the thickness direction b of the heat insulating layer 1.

ートと接する面は防水シート４を被装する。 The surface of the heat insulating layer 1 in contact with the formwork panel 3 and the periphery of the side are covered with a moisture-proof sheet 2. The moisture-proof sheet 2 is made of, for example, a polyethylene sheet (60 to 500μ) with high moisture permeability resistance. The surface of the heat insulating layer 1 opposite to the above surface, that is, the surface in contact with the poured concrete, is covered with a waterproof sheet 4.
上記型枠パネル３としては前述した従来公知の
型枠パネルを用い、また上記防水シート４として
は、例えばポリエチレンフオーム（独立気泡）の
スライス品を用いると良く、この透湿抵抗は比較
的小さく防水性能の良い材料である。 As the formwork panel 3, the conventionally known formwork panel described above is used, and as the waterproof sheet 4, it is preferable to use, for example, a sliced product of polyethylene foam (closed cell), which has a relatively low moisture permeability resistance and is waterproof. It is a material with good performance.

逃げるので、内部結露が生じにくく、従つて長期
間に亙り高い断熱性能が維持できる。 Further, if glass wool subjected to water repellent treatment is used as the heat insulating layer 1, it is possible to further prevent a decrease in heat insulating performance and durability due to water intrusion. Heat insulation layer 1
In addition to glass wool, rock wool can be used. What is important here is to select the materials of the waterproof sheet 4 and concrete so that the sum of their moisture permeability resistances is smaller than that of the moisture-proof sheet 2 in terms of moisture permeability resistance. In this way, moisture that has entered the heat insulating layer 1 escapes to the concrete side, making it difficult for internal condensation to occur, and therefore maintaining high heat insulating performance over a long period of time.
