[0002]

2. Description of the Related Art Conventionally, sealing between a roofing element, for example, a roof tile and a main building tile, uses a long sealing material body made of foamed rubber and a sealing material adhered to the lower surface thereof. Then, the sealing material is stuck on the top surface of the tiling with an adhesive material, and the main building tile is placed on the sealing material.

[0003]

However, the surface of a roofing element, for example, a roof tile, has inherent irregularities, and there are also large irregularities in the portion where the roof tiles overlap. With a conventional sealing material made of foamed rubber, there were cases where these irregularities could not be completely followed or filled. For example,
Even if the sealing material is made to follow the rectangular irregularities, a round gap is formed at the corner. Also, irregularities having a step of 15 mm cannot be filled with a 12 mm square sealing material. As described above, if a gap is formed between the roofing element and the sealing material, there is a problem that rainwater or the like passes through the gap.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to reliably seal a roofing element having many irregularities so that no gap is formed between the roofing element and a sealing material.
It is an object of the present invention to provide a novel roofing element sealing structure and a sealing method capable of preventing rainwater from passing through.

And affixed.

Here, as the material of the sealing material body, various rubbers such as CR (chloroprene rubber), EPDM (ethylene / propylene rubber), SBR (styrene / butadiene rubber), and various rubber-like resins are used. Can be illustrated. Examples of the foaming agent include various inorganic foaming agents such as sodium bicarbonate and various organic foaming agents such as N, N'-dinitrosopentamethylenetatramine. Examples of the conductive heating element include various electric heating materials such as nichrome and copper, and the form may be, for example, linear or plate-like. As an adhesive,

[0009]

According to the roofing element sealing structure or the sealing method of the present invention, the sealing operation can be performed easily and in a short time without skill by a simple operation of energizing the conductive heating element. Further, since the sealing material body and the adhesive are softened during the former foaming expansion, they are well adapted to the unevenness of the roofing element and adhere tightly without gaps. In addition, according to such a foaming method, the sealing material main body becomes substantially closed cells, so that the water shielding property is high. For this reason, the sealing property (watertightness) after construction is increased. Furthermore, by adjusting the foaming rate of the sealing material body, the adhesion to the roofing element can be adjusted.

[0010]

EXAMPLES Hereinafter, examples embodying the present invention will be described.
This will be described with reference to the drawings. First, a sealing material 1 shown in FIG. 1 includes a sealing material main body 2 formed in a long thin plate shape by EPDM containing a foaming agent, and the thickness of the sealing material main body 2 is 1 to 3 mm. The two conductive heating elements 3 made of a thin nichrome plate are attached (specifically, buried) to the sealing material main body 2 over substantially the entire length thereof so as not to come into contact therewith. An adhesive 4 is attached to both surfaces of the sealing material main body 2 over substantially the entire length, and a release paper (not shown) is applied before the application.

Now, for example, the sealing between the roof tile 8 and the main building tile 9 as shown in FIG. 2 is performed by using the sealing material 1 and by a construction method as shown in FIGS. First, as shown in FIG.
Is adhered by the adhesive 4 on the lower surface. At this time,
Has a unique unevenness on the upper surface thereof, and a large unevenness also exists in a portion where the cross tiles 8 overlap, so that the upper surface of the sealing material 1 stuck along these unevenness also has an uneven shape.

Next, the main building tile 9 is placed on the upper surface of the sealing material 1. As described above, since the upper surface of the sealing material 1 is uneven, the main building tile 9 has a portion that comes into contact with the adhesive 4 and a portion that comes close to the gap 5 with a gap 5 therebetween.
At this time, the conductive heating element 3 slightly protrudes from both ends of the sealing material body 2.

Subsequently, as shown in FIG. 1, the ends of the two conductive heating elements 3 protruding from one end of the sealing material main body 2 are brought into conduction by, for example, twisting, and the two protruding ends are protruded from the other end. A power supply device 7 such as a battery or a commercial power supply is connected to an end of the conductive heating element 3 via a lead wire 6. As described above, in this embodiment, two conductive heating elements 3 are buried,
By conducting the one end in a folded shape, it is possible to easily conduct electricity only from the other end. Note that the lead wire 6 can be freely extended in any direction.

Then, the conductive heating element 3 is energized and heated to expand and expand the sealing material main body 2 so as to eliminate the gap 5 as shown in FIG. The pressure-sensitive adhesive 4 on the upper surface of 2 is stuck and adhered.

As described above, the simple operation of energizing the conductive heating element 3 enables the sealing operation to be performed easily and in a short time without any skill. Also, since the sealing material body 2 and the adhesive 4 soften during the former expansion and expansion,
It fits well on the unevenness of the roof tile 8 and main building tile 9, and adheres tightly without gaps. In addition, according to such a foaming method, the sealing material main body 2 becomes substantially closed cells, and thus has high water shielding. For this reason, the sealing property (watertightness) after construction is increased. further,
By adjusting the foaming rate of the sealing material main body 2, it is also possible to adjust the adhesion to the cross tile 8 and the main building tile 9.

The sealing material and the sealing method of the above embodiment or the modified example are not limited to the sealing between the roof tile 8 and the main roof tile 9, but may be, for example, the floor tile 8 and the corner roof tile as shown in FIGS. 10, sealing between the roof tile 8 and the keraba metal accessory 11 as shown in FIG. 7, and sealing between the roof tile 8 and the roof tile 12 as shown in FIG. You can also.

Further, the present invention is not limited to the configuration of the embodiment, and can be embodied by appropriately changing the scope of the invention as follows, for example, as follows. (1) The adhesive 4 on the upper surface of the sealing material body 2 can be omitted. In this case, the sealing material main body 2 may not be stuck to the main building tile 9, but since the foaming expansion adheres to the main building tile 9, sufficient sealing properties can be obtained. (2) The sealing material 1 is attached to the main building tile 9 first,
Thereafter, the sealing material main body 2 may be foamed and expanded and adhered to the cross tile 8.

[0018]

As described above in detail, according to the roofing element sealing structure or the sealing method of the present invention, there is no gap between the roofing element and the sealing material between the roofing elements having many irregularities. Can be reliably sealed,
It has an excellent effect that it can block rainwater and the like.
