Abstract

PROBLEM TO BE SOLVED: To obtain an integral type, thin type and lightweight thermal insulating and sound- insulating material, which is easily handled, for a wall, a floor, etc., by abutting and installing piezoelectric high-molecular films, in which resistors are mounted at both ends, onto both surfaces of a glass wool material and packaging the outer circumferential surfaces of the films by a packaging material. SOLUTION: Piezolectric high-molecular films 11, in which resistors 12 are set up at both ends and thin-film electrodes are stuck on both surfaces, are abutted against both surfaces of glass wool 13, the outer circumferential surfaces of the films are packaged by a packaging material 14, and a thermal insulating and soundproof material 10 is constituted. The sound- insulating and soundproof material 10 is arranged between an outer well surface material 24 and an inner wall surface material 25 in a framework composed of vertical members 21, 21 and horizontal members 22, 23, and a wall panel 20 is configured. Vibrational energy in a low-frequency region of a sound from the outside is converted into electric energy, and heat is dissipated by the resistors 12 set up at both ends. A part converted into high frequency or a sound in a high-frequency region passed through the piezoelectric high- molecular film 11 is absorbed by glass wool 13. Accordingly, the thermal insulating and soundproof material can be executed as an integral type thermal insulating and soundproof material, and the execution of works is simplified and manhours can be reduced.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating / sound insulating material, and a structural member such as a building wall or floor using the heat insulating / sound insulating material.

2. Description of the Related Art In recent years, air conditioners have been remarkably popular in order to control the temperature of rooms in offices and homes for a comfortable life throughout the year. For this reason, building materials such as flooring materials, wall materials, and ceiling materials are used. The adiabatic effect of has come to be required.
In addition, noise generated during operation of air conditioners in general houses, etc., operation noise of electric equipment used at home, vibration noise caused by movement of people, and even outdoor caused by transportation and vehicles. The noise has become a social problem, such as the noise from the building entering the building.

In response to social needs such as heat insulation, sound insulation, and non-combustible building materials as described above, manufacturers of buildings and materials such as houses have a so-called sound insulation effect by absorbing and insulating sound such as walls, floors and sashes. We are working on the development of various materials.

An example of such a case is, for example, Japanese Patent Laid-Open No.
Japanese Patent Laid-Open No. 1-83655 describes vibration-proof concrete in which a piezoelectric material is used as a part or all of an aggregate of a material that constitutes concrete such as cement, aggregate, and water. This invention is intended to generate noise due to vibration and to prevent noise.

Further, as an example of the soundproof wall, PV which is a piezoelectric material is used.
An aluminum thin film is vapor-deposited on both sides of a DF (polyvinylidene fluoride) film to form electrodes, and both electrodes are connected by a resistor, which is provided on both sides of rock wool (NIKKEI MECHANICAL 199).
5.6.26 NO. 457 page 28).

However, in the above-mentioned conventional vibration-proof concrete, although the vibration-damping property and the sound-insulating effect are obtained, only the sound-insulating effect in the low frequency range is obtained, and the concrete wall. Although the sound insulation effect is improved by increasing the thickness, there is a problem that the weight and the thickness are excessively increased in building a building such as a general house.

Further, in the case of the rock wool soundproof wall provided with the latter piezoelectric film, a sound insulating effect from a low frequency range to a high frequency range is expected, but the structure of the soundproof wall is complicated, There is a problem in that the number increases, which requires a considerable number of construction steps for construction, resulting in cost increase.

The present invention has been made by paying attention to the above-mentioned conventional problems, and an object thereof is to solve these problems and to construct a wall, floor, etc.
Thin, lightweight, easy-to-handle, integrated heat insulation and soundproofing material, easy to construct walls and floors with less man-hours, heat insulation effect, and sound insulation effect from low frequency range to high frequency range.
The present invention provides a sound insulating material and constituent members such as walls and floors.

This vibration energy is once converted into electric energy by the resistor, and heat is generated and radiated. Due to this phenomenon, the low frequency is attenuated by heat generation and part of it is converted to high frequency, but this high frequency range is absorbed by the glass wool material or rock wool material, which is effective from low frequency range to high frequency range. It is possible to use it as a heat insulating / soundproofing material by effective sound insulation.
