Description

  The present invention relates to a soundproof ventilation material, and more particularly, to a soundproof ventilation material provided on a roof surface of a building and having a soundproof performance and a ventilation performance, and a roof portion soundproof ventilation method using the same.

  The roofs of ordinary houses include tiled roofs and sheet metal roofs, but in the case of sheet metal roofs, a metal sheet is directly struck against the field plate through a waterproof material, so a loud rain sound is generated during rainfall and transmitted indoors. Is done. In order to prevent the transmission of the rain sound, a heat insulating material may be attached to the back surface of the roof material, but basically no device specializing in soundproofing has been taken.

Further, as the sheet metal roof is heated by the sun and the temperature is increased, the waterproof material and the base plate are also heated and the durability is lowered. In addition, the high temperature of the sheet metal roof deteriorates the thermal environment of the back of the hut, and further, there is a problem that the durability is lowered due to the corrosion of the base plate.
JP 2001-65074 A Japanese Patent Laid-Open No. 7-90944

  As described above, the soundproofing measures by the heat insulating material are primarily for heat insulation, and rain sound, wind sound, falling sound of branches and leaves, etc. (hereinafter simply referred to as “rain sound”) falling on the sheet metal roof. ) Is not a sufficient soundproofing measure, and a soundproofing measure for a comfortable silent environment is being desired.

  The present invention was made in order to meet such a demand. By installing it between a field plate and a sheet metal roofing material, the soundproofing property of the house is enhanced, and the ventilation effect and the drainage effect are also exhibited. Another object of the present invention is to provide a soundproof ventilation material that can improve the thermal environment of the cabin and improve the durability of the house, and a soundproof ventilation method for the roof using the soundproof ventilation material.

  In order to solve the above-mentioned problem, the invention according to claim 1 proposes a soundproof ventilation material comprising a ventilation plate formed by molding a number of hollow cones on a plastic plate such as polypropylene, and the invention according to claim 2 A soundproof ventilation material is proposed in which a number of sound absorbing small holes are provided in a flat portion of the ventilation plate where the hollow cone is not formed.

  There is a case where a heat shielding material is applied to the entire bottom opening side of the hollow cone group of the ventilation plate. In addition, a plurality of the ventilation plates may be stacked in the same direction or in the opposite direction, and in that case, a heat shielding material may be sandwiched between the ventilation plates.

  In order to solve the above-mentioned problems, an invention according to claim 6 is a plate formed by depositing a large number of hard plastic monofilaments in a random loop shape to form a flat plate, the thickness portion of which is a plurality of rows. A soundproof ventilation material is proposed, which is composed of a ventilation plate including a cylindrical cavity portion to be provided and a loop crushing layer covering the front and back surfaces thereof.

  In order to solve the above-mentioned problems, the invention according to claim 7 is characterized in that the soundproof ventilation material according to any one of claims 1 to 6 is installed between the Nojizaka and the sheet metal roofing material, together with soundproofing, from the eaves. We propose a soundproof ventilation method for the roof part, which enables ventilation in the building direction and drainage from the building to the eaves direction.

  Since the soundproof ventilation material according to the present invention has the above-described configuration, it is installed between the base plate and the sheet metal roofing material, so that it can be used indoors by the action of a hollow cone, numerous sound absorbing small holes, or loop monofilaments. Transmission of rain sound is prevented, and there is sufficient ventilation space in the ventilation plate, so ventilation and drainage are performed at the installation site, moisture is released from the room sufficiently, and the thermal environment in the back of the hut is thus reduced. It has the effect of improving the durability of the house.

  The best mode for carrying out the present invention will be described with reference to the accompanying drawings. The soundproof ventilation material according to the present invention shown in FIG. 1 is composed of a ventilation plate 1 formed by molding a large number of hollow cones 3 on a plastic plate 2 such as polypropylene. Preferably, the hollow cones 3 of the plastic plate 2 are formed. An infinite number of sound absorbing small holes 5 having a diameter of, for example, about 1 mm are provided in the flat portion 4 that is not provided. The sound absorbing small hole 5 may be a through hole or a deep hole. In the figure, the sound absorbing small holes 5 are shown only in a part of the flat portion 4, but are actually formed over the entire area.

  The ventilation plate 1 is formed by, for example, forming a hollow cone 3 having a height of about 5 to 10 mm with a flat tip by embossing or the like on a plastic plate 2 such as polypropylene having a thickness of about 0.1 to 0.3 mm. It is densely provided. However, the density of the hollow cones 3 is such that the lower end skirts do not come into contact with each other, and a certain level of flat part 4 remains.

  In the example shown in FIG. 1, the hollow cones 3 in each row are arranged so as to be slightly shifted from side to side, but they may be arranged in a grid pattern vertically and horizontally. Further, the hollow cones 3 do not necessarily have such a regular arrangement, and may have an irregular arrangement.

  When it is necessary to ensure the thickness of the ventilation layer, a laminate of a plurality of ventilation plates 1 can be used. In the example shown in FIG. 3, a plurality of ventilation plates 1 (three in FIG. 3) are stacked in the same direction. In this case, a heat shielding material 6 such as an aluminum sheet that reflects heat rays may be sandwiched between the ventilation plates 1 and 1.

  Next, a construction example of the soundproof ventilation material will be described. The soundproof ventilation member is disposed between the base plate 11 and the sheet metal roof member 12 covered with moisture-permeable waterproof paper with the plastic plate 2 as the bottom surface (FIGS. 4 and 5). The fixing to the field board 11 is performed by a method such as nailing the portion as appropriate. FIG. 5 shows an example of construction in a building, and the soundproof ventilation material is arranged on both sides with the building opening 13 in between. Reference numeral 14 denotes a building ventilation material installed on the building opening 13.

  Thus, the rain sound generated in the sheet metal roofing material 12 is not directly transmitted to the field plate 11 through the ventilation plate 1, but the rain sound is transmitted through the hollow layer of the hollow cone 3 and the sound absorbing small holes. Since the sound is absorbed at 5, it attenuates considerably and is transmitted to the indoor side. Moreover, the space between each hollow cone 3 becomes the ventilation space 7, and the scavenging between the sheet metal roofing material 12 and the base plate 11 becomes possible.

  In addition, it cannot be overemphasized that the soundproof ventilation material which concerns on this invention can be used not only in the above sheet metal roof but in the case of a tile roof. However, in the case of a tile roof, there is a ventilation space by a tile rail, which means that there is more space for generating radiant heat than in the case of a sheet metal roof. Therefore, in that case, it is preferable to use a heat shield 6 (FIGS. 2 and 3) in which the bottom opening of the hollow cone 3 group of the ventilation plate 1 is covered.

  6 to 8 show another construction example of the soundproof ventilation member according to the present invention. The one shown in FIG. 6 is intended to discharge indoor moisture such as the back of a hut. A moisture permeable / waterproof sheet 8 is stretched on a field board, and a ventilation plate 1 is interposed on the heat shielding material 6 thereon. Place. The heat shield 6 in this case is appropriately formed with moisture permeable holes.

  In the construction example shown in FIG. 7, the moisture permeable / waterproof sheet 8 and the heat insulating material 6 are disposed on the base plate in the same manner as described above, the ventilation plate 1 is disposed thereon, and the projecting side of the hollow cone 3 is directed downward. It is a thing piled up.

  Further, in the construction example shown in FIG. 8, a moisture permeable / waterproof sheet 8 is stretched on the base plate, and the two ventilation plates 1 and 1 are placed on top of each other with the projections of the hollow cone 3 facing each other. The heat shield 6 is sandwiched between the ventilation plates 1 and 1.

  FIG. 9 shows a soundproof ventilation material constituted by a ventilation plate 1a having another configuration. This ventilation plate 1a is formed in a flat plate shape by depositing a large number of hard plastic monofilaments 15 in a random loop shape. The thickness portion of the plate includes a plurality of rows of cylindrical cavities 16 and a loop crushing layer 17 covering the front and back. This ventilation plate 1a is obtained by diverting the collection and drainage treatment material of Japanese Patent No. 3435145.

  The construction of the waterproof ventilation material using the ventilation plate 1a is also performed in accordance with the soundproof ventilation material. In this case as well, the rain sound generated in the sheet metal roofing material 12 is not directly, but through the ventilation plate 1 the field plate. 11, the rain sound is absorbed by the loop crushing layer 17 and the cylindrical hollow portion 16, and is therefore considerably attenuated and transmitted to the indoor side. Moreover, the space of the cylindrical cavity part 16 becomes a ventilation space, and scavenging between the sheet metal roofing material 12 and the field board 11 and drainage are possible.

  Although the present invention has been described in some detail with respect to its most preferred embodiments, it will be apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention, the invention being defined by the appended claims. It is not restricted to the specific embodiment other than limiting in.
