TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for attaching a heat insulating sound absorbing material , and more particularly, to a method for mounting a heat insulating sound absorbing material made of inorganic short fibers.
[0002]
[Prior art]
Insulating sound absorbing materials of the type described above have been known in the past, and inorganic short fibers used for such insulating sound absorbing materials include glass fibers, rock wool, slag wool, alumina fibers, and potassium titanate fibers. , Carbon fiber, metal fiber and the like, and glass fiber is usually used.
Such a heat insulating and sound absorbing material is manufactured, for example, as disclosed in JP-A-59-82454.
That is, the molten glass is caused to flow down to a spinner rotating at a high speed, and is spun by a centrifugal force from a fine hole provided in a side wall of the spinner to be fiberized (centrifugal method) to produce short glass fibers. Thereafter, a thermosetting resin such as a phenol resin, which is a binder between the fibers, is applied to the glass short fibers flowing downward by the airflow by a binder spray nozzle provided below the apparatus for producing the glass short fibers. Spray. The fibers onto which the phenolic resin has been sprayed travel in the cotton collecting box direction together with the airflow. In this cotton box, for example, a cotton collection conveyor made of a mesh-like collection net is moving, and the back surface thereof is sucked by a suction blower so as to have a pressure lower than the atmosphere, that is, a negative pressure. The fibers are deposited and laminated on the cotton collection conveyor in a flocculent manner. The fibers that have been deposited and layered into a cotton form exit the cotton collecting box and then go to a cure oven that cures the binder and adjusts the thickness of the product. In this cure oven, hot air at a controlled temperature is passed between cottons to cure the resin, thereby bonding the fibers together to form a mat-like product having a constant thickness. Thereafter, the product is cut into desired dimensions to obtain a product.

[Problems to be solved by the invention]
However, the heat-insulating sound-absorbing material manufactured as described above has a large bonding strength in the plane direction between the fibers because the fibers are simply laminated, etc. There is a large problem that the bonding strength is weak and delamination is likely to occur. In addition, due to the drawback that delamination tends to occur, volume expansion occurs over time, and effective sound absorption and heat insulation cannot be achieved. In severe cases, the layer may be separated from the installation location. Further, the above-mentioned conventional heat insulating and sound absorbing material has poor compressive deformation and flexibility in the surface direction. Therefore, when the installation place is narrow, it is cut to reduce the width or the installation place is curved. In such a case, there is also a problem in operability such that a slit must be formed on one surface at a predetermined interval.
The present invention has been made in view of the problems of the prior product, unlikely to delamination, the compressibility of the surface direction, to provide flexibility to the excellent thermal insulation sound absorbing material, the reinforcing member of T-shaped cross section to the wall member It is an object of the present invention to make it very easy to attach and install a heat insulating and sound absorbing material even when provided .
[0004]
[Means for Solving the Problems]
The heat-insulating sound-absorbing material according to the present invention is formed by folding a heat-insulating sound-absorbing material obtained by accumulating inorganic short fibers in a zigzag manner in one direction in the plane direction, and is substantially perpendicular to the plane direction, It comprises a plurality of rising portions raised in parallel, and a plurality of connecting portions for connecting adjacent ones of the rising portions alternately at an upper portion and a lower portion. The lower surface is formed in each part, and it is formed to have a substantially uniform thickness, and is integrally and integrally formed with a binder for binding the fibers, and one of the upper surface and the lower surface is installed on the member. A method of attaching a heat insulating sound absorbing material as a surface, wherein a reinforcing member having a T-shaped cross section is provided by separating a joint between adjacent rising portions and straddling a reinforcing member having a T-shaped cross section. Wall material To the installation surface, and it is characterized in that the attaching and along the heat insulating acoustic material.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The heat-insulating sound-absorbing material of the present invention has a zigzag shape folded in the surface direction as described above, and is integrally formed integrally as a whole, so that delamination does not occur unlike a conventional product. . Further, the folding direction has compressibility in the plane direction, so that even if the width of the heat insulating and sound absorbing material is narrower than the width of the installation place, installation is possible by compressing in the direction. Further, even in the case where the wall member is provided with a reinforcing member having a T-shaped cross section, it can be straddled by separating the joining between the adjacent vertical portions of the corresponding portion, Even in such a case, the installation and installation of the heat insulating and sound absorbing material can be performed extremely easily.
