DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single construction method for preventing blisters, which can smoothly remove moisture and the like from a roof foundation.

[0002]

2. Description of the Related Art Conventionally, as a single waterproof underlaying material, a waterproof material having an adhesive applied to the entire surface is often used. However, if the underlaying material is adhered to the entire surface, the underlaying material may be cracked due to the influence of cracks in the underlying concrete or the like, and "blowing" may occur due to the moisture generated from the underlying material. Such movement of the groundwork and "swelling"
In order to cope with this problem, a perforated roofing method has been used in which a communication path through which moisture can pass is left behind on the roofing member. Even with such a perforated roofing, in order to completely prevent "bulging",
A degassing tower as shown in FIG. 1 is required. However, on sloped roofs, installation of deaeration towers that protrude from the roof surface is disliked mainly for aesthetic reasons.

[0003]

An object of the present invention is to provide a new single construction method for completely preventing swelling of a roofing material that is roofed using a single without providing a degassing tower on the roof.

[0004]

The first aspect of the present invention is that: (a) an underlaying material partially coated with an adhesive material so that all the non-adhesive material-free portions are in communication with each other over the entire roof base except for a certain area of the ridge portion; (B) Then, as in the case of the above-mentioned underlaying material, the adhesive material is partially applied, and the underlaying material for the building is provided at least at the lower end on the above-mentioned underlaying material on the ridge portion where no underlaying material is attached. And (c) further applying a single as a roofing material thereon using an adhesive, the method being applied to prevent swelling. The second aspect of the present invention is as follows: (a) Affixing a roofing material partially covered with an adhesive so that all the adhesive-free portions are in communication with the entire roof base including the ridge portion; ) Then, a part of the underlaying material adhered to the ridge portion is cut out, and (c) a ridged underwear material is attached so as to sufficiently cover the cutout portion,
(D) Further, the present invention relates to a swelling prevention single construction method, wherein a single as a roofing material is adhered thereon using an adhesive. A third aspect of the present invention relates to the method for preventing blistering single construction according to claim 1 or 2, wherein a degassing material is inserted into an arbitrary portion of the lap portion of the underlaying material on the inclined surface of the roof in the underlaying material attaching step.

The above-described embodiment in which the adhesive is partially applied so that all the non-adhesive-free portions are in communication is not limited as long as it meets its purpose.
Nos. A, B, and C show examples (the figure shows only a small portion of the underlaying material). A is a type in which an adhesive is applied in a polka dot shape, and B and C are types in which an adhesive is applied in a stripe shape. In C, an adhesive material is applied in a belt shape to ensure watertightness of the wrap portion. In the case of A and B, it is preferable that the wrap portion is made in this manner. When the underlaying material is adhered to the roof foundation, only the peripheral area of the roof at least about 30 to 50 cm from the edge of the roof, that is, the peripheral area surrounding the entire roof (eave tip and Kebara part),
It is preferable to provide an adhesive material on the entire surface and take measures to prevent the underlay material from being turned up by a strong wind such as a typhoon. The roofing material for the ridge may be the same as a normal roofing material, or may be a dedicated one adapted to the shape of the ridge. The roofing material refers to a normal single material such as asphalt. Of course, a single material subjected to non-combustibility treatment is also included. There is no particular limitation on these adhesives, and among the general-purpose adhesives prepared using synthetic resins, synthetic rubbers, natural rubbers, recycled rubbers and the like as main raw materials, the above-mentioned roofing material and underlaying material and the base material such as concrete can be used. If the adhesiveness is good and the alkali water resistance is high, it can be adopted. As a specific example of the pressure-sensitive adhesive, the following composition can be obtained. SBS (Styrene / Butadiene / Styrene / Block Copolymer) 20 parts by weight Petroleum resin (tackifier) 10 parts by weight Asphalt 40 parts by weight Process oil 30 parts by weight It is set in consideration of widening the gap formed between the bases. 0.
What is necessary is just about 3-1.0 mm.

The first invention will be described with reference to FIG. For example, as shown in FIG. 2C, a roofing material 2 provided with an adhesive layer is stuck on a roof foundation 1 such as concrete or ALC. However, a certain area having a width of, for example, about 50 to 150 mm from the ridgeline of the ridge is left unattached. Then, a ridge underlaying material 3 having a size of 100 mm or more is attached so as to cover the predetermined area and sufficiently secure a lap portion with the underlaying material 2. Depending on the gradient,
If it is 100 mm or more, a normal gradient (3/10 gradient) can prevent backflow of rainwater. The pressure-sensitive adhesive material of the building roofing material is also provided with a pressure-sensitive adhesive layer having a shape as shown in FIG. 2C.
Finally, a single as a roofing material is applied, and the construction is completed. The moisture is degassed as indicated by arrow 6.

The second invention will be described with reference to FIG. In the first invention, the underlay material was not adhered to a certain area of the ridge, whereas in the second invention, the entire roof base 1 including this part was adhered as shown in FIG. 2C. The underlaying material 2 provided with the material layer is attached (see FIG. 4A). Next, a part of the roofing material (7 in FIG. 4A) of the ridge portion is cut off with, for example, a cutter. The size of the cutout portion is not particularly limited, but is set to a size of about 50 mm to 200 mm, preferably about 80 to 120 mm, and about 100 to 500 mm, and preferably about 250 to 350 mm from the viewpoint of workability and economy. Then
The cut-off portion is sufficiently covered, and a wrap portion that does not cause backflow of rainwater is taken, and the ridge roofing material 3 is attached. The ridge roofing material 3 preferably has a shape as shown in FIG.
If the dashed line is attached to the ridgeline of the ridge, the lower part cannot be parallel to the eaves line, so it is impossible for the whole to overlap with the single adhesive part. The construction can be performed without the necessity of giving attention to important points. In addition, it is preferable that the adhesive material of the roofing material used for the building is applied in a form as shown in FIGS. 2A and 2B so that moisture can escape in any of the vertical and horizontal directions. Further, a single as a roofing material 4 is stuck thereon. 4B is a cross-sectional view taken along the line XX.
FIG. 4C is a sectional view taken along line YY.

In a third aspect, in the first or second aspect, a degassing material is inserted into an arbitrary portion of a lap portion between the lowering materials during construction of the lowering material to further improve degassing efficiency. It is assumed that. As the deaeration material, one having a structure shown in FIG. 6A can be used, and an underlaying material cut into the shape shown in FIG. 7 can be used as the deaeration material. The degassing material having the structure shown in FIG. 6 can dehumidify the moisture accumulated in the lower layer of the roofing material 2 from the opening 12 through the hole 11.
In the structure shown in FIG. 7, since the lower side is cut diagonally, the deaeration opening of the deaeration material happens to overlap with the single adhesive layer as in FIG. This is preferable because there is no case where the air is blocked. The size of these degassing materials is not particularly limited, but the width 50
~ 250mm, preferably 120 ~ 180mm, length 2
It is 00 to 400 mm, preferably 250 to 350 mm. Such a deaeration material is particularly effective when the distance from the roof ridge to the eaves is a large area such as 7 m or more. One example of the construction method of the third invention is shown in FIG.
B. It can be seen that the deaeration material 8 has been inserted into the wrap portion of the underlaying material 2. FIG. 8B is a plan view showing a state in which the deaeration material 8 is inserted into an arbitrary portion of the lap portion of the underlaying material. A is, of course, a cross-sectional view of the roof.

[0009]

According to the construction method of the present invention, deaeration of a single roof can be completely achieved without providing a deaeration tower, and a single blister can be expelled.
