JP4859188B2 - Heat-insulating and heat-insulating ventilation material, roof ventilation using the same, and roof ventilation method - Google Patents

Description

  The present invention relates to a heat-insulating / heat-insulating ventilation material, more specifically, a ventilation material having heat-insulating and heat-insulating properties installed on a roof surface or a wall surface of a building, and roof ventilation using the same, and a hut. It relates to the back ventilation method.

  Since sunlight hits directly on the roof and wall surface of the building and becomes high heat, a heat insulating material is stretched on the roof and wall in order to prevent the heat from being transferred into the room.

The heat countermeasure by the heat insulating material is intended only for heat insulation and exhibits a certain effect, but cannot be a heat countermeasure against the radiant heat transmitted through the space.
JP-A-6-185130 Japanese Patent Publication No. 6-54035 JP 2001-342695 A JP 2003-138664 A JP 2003-160981 A JP 2003-184216 A JP 2004-36255 A

  As described above, since the conventional method using a heat insulating material has no measures against radiant heat other than heat insulation, it is difficult to say that it is sufficient as a heat measure for a comfortable thermal environment.

  Therefore, the present invention provides heat insulation, heat insulation and moisture release from the room by installing it using a ventilation space formed between the tiles on the roof surface and between the ventilator edges on the wall surface. Providing a heat insulating and heat insulating ventilation material that can enhance the durability of the house and the indoor thermal environment, and can also exert a noise-reducing effect, and a roof ventilation and hut ventilation method using the same. This is the issue.

According to a first aspect of the present invention for solving the above-described problem, a vent plate in which a number of hollow cones are molded is provided on a plastic plate such as polypropylene, and the entire surface of the vent plate on the bottom opening side of the hollow cone group. It is a heat-insulating / heat-insulating ventilation material formed by covering a heat-insulating cover with a thin heat-insulating material.

In one embodiment , an infinite number of sound absorbing small holes are formed in a flat portion of the plastic plate where the hollow cone is not provided.

Further, the invention according to claim 3 for solving the above-mentioned problem is described in claim 1 or 2.
Heat insulation and heat insulation ventilation, characterized in that ventilation from the eaves to the building opening is made possible by installing the heat insulation and heat insulation ventilation material described in 1. This is a method of ventilation and roof ventilation using materials.

Since the heat-insulating / heat-insulating ventilation material according to the present invention has the above-described configuration, it is added to the conventional heat-insulating material and installed in the ventilation space existing on the roof surface or wall surface with its heat-insulating cover as the heat-receiving side. , Heat transfer to the indoors is prevented by the action of the air layer formed between the heat shield cover, the heat insulating material and the hollow cone, thereby improving the thermal environment of the building, and between the hollow cones or in the cylindrical shape Since there is sufficient ventilation space in the cavity, moisture can be released from the room without impairing the air permeability of the installation location, and there is an effect that the durability of the house can be improved. There is an effect that the ventilation space where the wall surface is not used can be effectively used.

In the invention according to claim 2 , since the infinite number of sound absorbing small holes are formed, there is a further silencing effect, and in the invention according to claim 3 , the roof and roof tiles are spread over a wide area. It is possible to scavenge in the space between the base plate (specifically, between the heat shield cover and the base plate), which improves the durability of the house combined with the ventilation of the back of the hut, and the indoor thermal environment Has the effect of improving.

  The best mode for carrying out the present invention will be described with reference to the accompanying drawings. The heat insulating and heat insulating ventilation material according to the present invention is provided with a ventilation plate 1 formed by molding a number of hollow cones 3 on a plastic plate 2 such as polypropylene, and on the bottom opening side of the group of hollow cones 3 of the ventilation plate 1. The heat shield cover 6 is covered.

  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. Is provided. The density is usually such that the flat space 4 remains without the bottom hems of the hollow cones 3 being in contact with each other. Even if they are arranged, because of the conical shape, it is possible to ensure a sufficiently breathable air passage 5 between the hollow cones 3.

  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.

A heat shield cover 6 such as an aluminum sheet is mounted on the entire back surface of the plastic plate 2, that is, the entire surface opposite to the surface on which the hollow cone 2 is formed via a thin heat insulating material 7.

  When the ventilation layer needs to have a thickness, 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, the upper and lower hollow cones 3 and 3 are stacked so that the upper and lower hollow cones 3 and 3 are displaced from each other so that the upper and lower hollow cones 3 are not stacked to each other. Alternatively, a heat shielding cover 6 or the like is inserted.

  In the example shown in FIG. 4, two ventilation plates 1 and 1 are bonded together so that the hollow cones 3 face each other.

  Infinite numbers of small sound absorption holes 8 having a diameter of about 1 mm may be provided in the flat portion 4 of the plastic plate 2 where the hollow cone 3 is not provided. In FIG. 1, the sound-absorbing small holes 8 are shown only in a part of the flat portion 4, but actually, they are formed over the entire area.

Next, a construction example of the heat shield / heat insulating ventilation material according to the present invention will be described. The example shown in FIG. 5 is an example of construction on the roof surface of the ridge. In this case, the heat shield cover 6 is disposed between the tiles 12 on the field board 11 covered with moisture-permeable waterproof paper. . Fixing to the base plate 11 is performed by a method such as nailing a portion as appropriate. Thus, the radiant heat transmitted through the space 14 between the ventilation plate 1 and the roof tile 13 is reflected by the heat shield cover 6 and is not transmitted to the indoor side.

The construction method can be used for scavenging the space portion 14. That is, by using a roof frame that can be ventilated, the wind rising from the eaves side through the field plate 11 passes through the roof frame 12 and rises through the ventilation path 5 of the ventilation plate 1. It is discharged from the building opening 15. In this case, a plurality of laminated ones can be used as the ventilation plate 1 in order to secure a large ventilation space.

  In the case of this construction method, scavenging in the space 14 (specifically, between the heat shield cover 6 and the field plate 11) is possible over a wide range of the roof surface. Thus, in combination with attic ventilation, it is possible to improve the durability of the house and improve the indoor thermal environment.

  In addition, it cannot be overemphasized that the heat insulation and heat insulation ventilation material which concerns on this invention can be used not only in the above-mentioned tile roof but in the case of a sheet metal roof. However, in the case of a sheet metal roof, it is common to construct (fasten) directly on a field plate unlike a tiled roof. According to this, there is no ventilation space since there is no roof tile 12, which means that there is no space for generating radiant heat. Therefore, the usage method which constructs | stacks what laminated | stacked the ventilation plate 1 on both sides of heat ray reflective materials, such as an aluminum sheet, can be considered.

The example shown in FIG. 6 is an example of construction on a wall surface. In this case, the heat shield cover 6 is disposed on the outer surface of the base material 15 that is struck against the pillars 13 and the inter-columns 14. In the illustrated example, the heat insulating / heat insulating ventilation material is fixed to the base material 15 before the vertical body edge 16 is applied, and then the vertical body edge 16 is applied from above. The material may be fixed to the base material 15 between the vertical body edges 16 after the vertical body edge 16 is struck to the base material 15.

  In order to make it easy to hit the base plate 11 or the base material 15 or the like, the heat shield cover 6 is made larger than the ventilation plate 1 so as to protrude from the ventilation plate 1, and the protruding portion is used as a nail location or the like. You may make it utilize.

  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.
