Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a gap in a room such as an agricultural / horticultural house or a general house where airtightness is required, in which a synthetic resin corrugated sheet is used as an exterior covering material such as a roof material The present invention relates to an airtight filler for filling.

[Conventional technology]

Conventionally, various kinds of airtight fillers for agricultural and horticultural houses have been used. For example, a soft polyurethane foam material or a soft rubber foam material, etc., all of these foam materials have water permeability, it is possible to pass the water droplets generated on the back surface of the roof material, , Was able to be inserted in a narrow gap. However, the fillers using these foams also have the following problems.

[Problems to be solved by the device]

That is, when the above soft foam is used as an airtight filler for agricultural and horticultural houses, it is a foam having water permeability, but there is a problem that when it is pushed into a narrow gap, the water passage is crushed and the water passage function deteriorates. It was In addition, there is a problem in that the foam deteriorates from the surface thereof due to the influence of ultraviolet rays or the like, and is broken into pieces in a short period of time, and the airtightness of the house is lost. Therefore, in order to prevent such ultraviolet deterioration, an acrylic resin is applied to the surface of the foam or the foam is impregnated with tar or the like to improve the weather resistance.

However, such a means for improving the weather resistance is to block the water passage of the foam, and the water passage function is significantly lowered. When such an airtight filler having a reduced water-passing function is used, there is a problem that water droplets generated on the back surface of the roof material fall into the room from the position of the foam and adversely affect plants.

The present invention has been made in view of the above problems,
It is an object of the present invention to provide an airtight filler which has sufficient airtightness, has water permeability, is easily inserted into a gap, and can withstand long-term use.

[Means for solving the problem]

The airtight filler for agricultural and horticultural houses of the present invention is characterized in that a soft foam layer having good weather resistance is attached to the upper side or both sides of a fiber layer having water permeability, and an adhesive layer is provided as the lowermost layer. It is what

[Action]

Since the airtight filler of the present invention can send water droplets generated on the back of a roofing material or the like downward through the fiber layer having water permeability, the water droplets do not drop into the house, and
Since the soft foam layer adhered to the upper side or both sides of the fiber layer is flexible, it can be filled without a gap between the back surface of the roof material and the main building material, and moreover, with a roof material through which ultraviolet rays and the like pass. Even if there is, since the foam layer has good weather resistance,
Extreme deterioration does not occur. Also, the fiber layer is
Since it is more rigid than a soft foam, it is easy to push the filler into the small gap between the roof and the purlin,
The workability is far better than that of the conventional soft foam alone, and the airtightness in the house is kept extremely good.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of an airtight filler of the present invention, wherein 1 is an airtight filler and 2 is a fiber layer. The fiber layer 2 is not particularly limited, such as natural fiber and synthetic fiber, but it is preferably a fiber having good water permeability and having hydrophilicity. In other words, it is easy to absorb water droplets and water easily moves in the fiber. Things are good. For example, felt or the like can be preferably used.

Adhesives or adhesives are applied as adhesives 5 and 6 to the upper and lower surfaces of the fiber layer 2, and soft foam layers 3 and 4 are adhered to the upper and lower surfaces, respectively. The foam layers 3 and 4 are preferably soft urethane foams and have open cells, and EPDM (ETHYLENE-PROPYLENE-DIENE TERPOLYMER) and the like can also be used. Since these foams are easily deteriorated by ultraviolet rays, they are used by coating or including tar or acrylic flexible paint. By using tar or paint in this way, the rate of deterioration becomes extremely slow, and the foam layers 3 and 4 can maintain a state close to the initial quality for a long period of time. Further, it goes without saying that the foam layer 3 or 4 may be made of a foam material whose molecular structure does not easily decompose. Further, when the adhesive or pressure-sensitive adhesive 8 is applied to the lower surface of the foam layer 4, the filler 1 is used as a main material, a frame,
It is very convenient because it can be used by attaching it to a pillar or threshold. The adhesive 8 is covered with a release paper 7 or the like. Although the size of the airtight filler 1 for agricultural and horticultural houses of the present invention is not limited, the thickness of the fiber layer 2 is usually about 7 mm, the thickness of the foam layers 3 and 4 is 5 to 12 mm, and the width is The fiber layer and the foam layer are the same, and those having a thickness of 12 to 15 mm are preferably used.

FIG. 2 is a side view showing a state where the filler 1 of the present invention is used.

10 is a roofing material using corrugated sheet made of synthetic resin, and 11
Is an aggregate of a house such as a main building material. The water droplets 12 generated on the back surface of the roof material 10 move in the direction of arrow p along the gradient of the roof material 10. Then, the water droplets 12 pass through the fiber layer 2 in the filling material 1 of the present invention, adhere to the back surface of the roofing material 10 again, move downward along the roofing material 10, and are discharged out of the house.

In the embodiment shown in FIGS. 1 and 2, the foam layers 3 and 4 are adhered to both upper and lower surfaces of the fiber layer 2, but the foam layers do not necessarily have to be provided on both sides, and the lower foam layer 4 is not necessarily provided. It does not have to be. In that case, the lowermost adhesive layer may be provided on the lower side surface of the fiber layer 2.

Further, a method of attaching the filling material 1 of the present invention to a house or the like will be briefly described.

When a new roofing material is to be stretched over the main building material, the release paper 7 of the adhesive 8 is peeled off on the main building material while being attached to the main building material.
Stop the roofing materials such as corrugated sheets from above with screws. In this way, the filler 1 is less likely to be twisted or bent, so that good water permeability is maintained. In the case of a gap between the roof material of an existing house and the main building material, the fiber layer 2
It is advisable to insert the fiber layer 2 into the gap so that the fiber layer 2 is not bent as much as possible. Needless to say, the airtight filler of the present invention is used for keeping airtightness of general houses other than agricultural and horticultural houses.

[Effect of device]

As is clear from the above description, the airtight filler of the present invention can maintain satisfactory airtightness when used in an agricultural and horticultural house, and allows water droplets flowing on the back surface of the roof to pass smoothly through the filler. There is an effect that can be. Moreover, since the soft foam layer adhered to the upper side or both sides of the fiber layer follows the unevenness of the roof material without any gap, it has the effect of increasing the airtightness. Furthermore, since the filler of the present invention has a fiber layer having an appropriate rigidity therein and has a very flexible soft foam layer on one or both sides thereof, the filler of the present invention is pushed into a small gap. When it adheres to the main material in a straight line, it has a remarkable effect that the work is easy and the construction period can be shortened because the inner fiber layer serves as a core.
