Abstract

PROBLEM TO BE SOLVED: To provide a new roof lining having advantages over conventional rolled roof linings having waterproof self-adhesion layers, by solving the problems with conventional roof linings rolled in forward or reverse direction that the lining rolled in forward direction costs high to manufacture although easy to install, while the lining rolled in reverse direction has poor workability although inexpensive. SOLUTION: This roof lining has a separable sheet affixed to a waterproof self-adhesion layer and is wound into a roll (reverse) with the separable sheet facing inwards; the separable sheet at the terminal end of the roll is affixed to the opposite part of the roll. A portion of the separable sheet at the terminal end of the roll is peeled to expose the waterproof self-adhesion layer, with the end of the layer affixed to a sheathing board; as the roll is unwound to affix the end, the separable sheet is naturally separated with a delay of one turn while overlying the back of the roll.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the construction of roofing materials such as tiles, slate, and metal, which are applied to a roofing board on which the roofing materials are to be constructed, thereby ensuring the waterproofness of the roof. It relates to roofing materials.

Some roofing materials have a waterproof and self-adhesive layer mainly composed of asphalt. When the roofing material having the waterproof / self-adhesive layer is wound into a roll and sold and stored as a product, a release sheet is attached to the waterproof / self-adhesive layer. Therefore, at the time of construction, it is applied while being unwound from the state of the roll on the ground board.

By the way, there are two types of roof underlaying materials having a waterproof and self-adhesive layer wound in a roll shape, depending on the winding method.
A forward-wound roll with the release sheet attached to the waterproof and self-adhesive layer facing outward and a reverse-wound roll with the release sheet attached to the waterproof and self-adhesive layer inside. It is.

[0004] In the former case (a normal winding type), as shown in FIG. 5 (a), first, the release sheet 2 at the end of the roll is peeled off to expose the waterproof / self-adhesive layer 3. Attach the tip of No. 3 to a predetermined pasting start position of the base plate 4,
Thereafter, the roll is pulled in the direction of the arrow H, and the release sheet 2 is sequentially rolled while peeling off. The peeled release sheet 2 is processed so as to be rolled up and gathered as indicated by the symbol M on the pulling side of the roll.

[0005] The latter (reverse winding) is shown in FIG.
And peeling off the release sheet 2 at the end of the roll to expose the waterproofing / self-adhesive layer 3, and sticking the tip of the waterproofing / self-adhesive layer 3 to a predetermined sticking start position of the base plate 4; Thereafter, the roll was pulled in the direction of the arrow H and stuck, and it was difficult to perform the same procedure as in the case of the forward winding. This is because, in the case of the reverse winding, if the peeled release sheet 2 is rolled up like the normal winding on the pulling side of the roll while being rolled up as indicated by the symbol M ′, the roll is put on the peeled release sheet 2. Therefore, when the roll is applied in a direction perpendicular to the inclination on the inclined roof, the roll is liable to slide in a low direction on the release sheet 2 and cannot be applied straight, and several workers are required to attach the roll.

[0006] Therefore, in the case of a reverse winding, the roll is rolled and stretched to a required length without cutting off the release sheet, cut and then re-wound like a normal winding, and adhered according to the normal winding procedure. Therefore, there is a problem that extra work is required at the time of construction. From the viewpoint of workability, it can be said that the forward winding is superior to the reverse winding.

[0007]

However, in the case of the above-mentioned regular-winding type, when the manufactured roof underlaying material body is wound into a roll shape, the peeling sheet goes out of the main body, so that it extends like a crepe paper. The use of a material that is inexpensive (expensive compared to flat release paper that does not stretch) must be used (wrinkles come closer to the main body side), and therefore, there is a problem that the manufacturing cost increases. Was. In this regard, the reverse-wound type has an advantage that it can be manufactured at low cost because the release sheet goes inside the main body and can be rolled up using a flat release paper at low cost.

The present invention is intended to solve the above-mentioned problems of the forward winding type and the reverse winding type, and to take advantage of the advantages. The present invention is simple in construction and can be applied in a direction perpendicular to the inclination of the inclined roof. However, it is an object of the present invention to provide a new roof underlaying material that has good workability and can keep manufacturing costs low.

[0009]

Means for Solving the Problems In order to achieve the above object, a roofing material according to the present invention comprises a waterproof sheet and a self-adhesive layer having a release sheet attached thereto, and the release sheet side inwardly wound into a roll. The peeling sheet at the end of the roll is adhered to the roll side facing the roll, a part of the peeling sheet at the end of the roll is peeled off to expose the waterproof / self-adhesive layer, and the tip is a base plate. Then, when the roll was rewound and pasted sequentially, the peeling sheet was spontaneously peeled off with a delay of one round, with the peeling sheet overlapping the back side.

[0010] Further, the roof underlaying material according to the invention of claim 2 is characterized in that the release sheet is a transparent or translucent material, and is attached to a field board while unrolling a roll. In addition, even if the release sheet overlaps the back side with a delay of one round, the construction can be carried out without bending along the black ink on the baseboard while seeing through both edges of the roofing material.

[0011] Further, a roof underlaying material according to the invention of claim 3 is characterized in that an adhesive member for bonding between the release sheet and a roll side facing the release sheet is attached. In the case where the roof underlaying material remains due to the construction, the peeling sheet at the start of the roll application can be bonded to the roll side facing the roll using the attached double-sided adhesive member.

[0012]

Next, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic side view of the roofing material of the present application, FIG. 2 is an enlarged view of a portion A in FIG. 1, FIG. (B) is a state in which the peeling sheet is superimposed on the upper surface with a delay of one round, FIG. 4 is an explanatory view showing the effect of the end of the application of the roofing material of the present application, (a) is a state immediately after the end of the application,
(B) shows a state in which the release sheet has been peeled off.

FIG. 1 shows a roof underlaying material 10 of the present application.
In the roof underlaying material 10 of the present application, a release sheet (indicated by “dashed line”) 13 is attached to a waterproof / self-adhesive layer (indicated by “dots”) 12 formed on one side of a base cloth 11, with the release sheet 13 side inward. And the release sheet 13 at the end of the winding
End 13a is bonded to the roll (the back side of the base cloth 11) facing this via an adhesive 14 (see FIG. 2).

The adhesive 14 used for bonding the release sheet 13 and the back side of the base cloth 11 only needs to have an adhesive strength stronger than the adhesive strength between the waterproof / self-adhesive layer 12 and the release sheet 13. . Since the contact surface of the release sheet 13 with the waterproof / self-adhesive layer 12 has been subjected to the release treatment, the adhesive force is extremely weak or almost zero. As the adhesive 14, a quick-drying commercially available adhesive or a double-sided adhesive tape can be used. This is effective in easily and inexpensively manufacturing the roof underlaying material 10 of the present application.

The waterproofing / self-adhesive layer 12 satisfies the waterproofing property of the roof underlaying material and also has the adhesion to the field board 15. In other words, the roofing material (tile, slate, etc.) that comes into close contact with the entire surface of the baseboard
Even if rainwater enters through the nail hole for fixing the water, the water does not flow over the entire surface of the base plate, so that excellent waterproof performance is exhibited.

The waterproofing / self-adhesive layer 12 is obtained by mixing asphalt as a main material with an adhesive. Further, it is desirable that the pressure-sensitive adhesive material be formulated so as to be self-adhering depending on the temperature at the time of construction (a wide range from low to high depending on the time). In addition, the waterproofing / self-wearing layer 12 is not only the same layer having both functions of waterproofing and self-wearing,
It is a matter of course that the waterproof layer and the self-adhesive layer may be divided into layers.

In the roof underlaying material 10 of the present application, the waterproof / self-adhesive layer 12 is formed on one side of the base cloth 11 as the present embodiment, but the base cloth 11 is buried in the middle layer of the waterproof / self-adhesive layer 12. It may be made to be. In this case, a treatment for eliminating the adhesive force is performed by providing a mineral powder layer (not shown) or a synthetic fiber nonwoven fabric (not shown) on a surface (rear side) not used as an adhesive surface.

The base cloth 11 is made of a synthetic fiber non-woven fabric impregnated with asphalt. This asphalt does not matter whether it is straight asphalt or blown asphalt. The material fibers of the nonwoven fabric are not particularly limited, but plastic fibers such as vinylon and polyester are preferable. The thickness is 30 ~
100 g / m2 is suitable.

Next, the operation of the roof underlaying material 10 of the present invention described in the above embodiment will be described. Since the end 13a of the release sheet 13 at the end of the roll (which is also the start of application) is adhered to the back side of the base cloth 11 via the adhesive 14, first, the adhered portion is left as it is. Release sheet 1
The base material 11 is peeled off from the substrate 3. As a result, the waterproof / self-adhesive layer 12 is exposed.
Is pasted to a predetermined pasting start position P of the base plate 15 as shown in FIG.

Next, the roll is rolled while being pulled in the direction of arrow H. In the rolling, a jig (not shown) which can be locked to the center tube 16 of the roll may be used to pull the roll. Thus, when the roll makes one round, the release sheet 13 is naturally peeled off from the adhesive 14 on the back side of the base cloth 11 in a state of overlapping with the back side of the base cloth 11 as shown in FIG.

The operation of the peeled sheet 13 (the part overlapping the back surface of the base cloth 11) is continued as it is, but in this case, the peeled sheet 13 is formed of a transparent or translucent material. In other words, as described above, even if the release sheet 13 overlaps with the back side of the base cloth 11 with a delay of one round, both edges of the base cloth 11 can be seen through and constructed without bending along the ink applied on the base board. become able to.

Then, as shown in FIG. 4A, the roll reaches the predetermined sticking end position P 'on the base plate 15, and the roof underlaying material 10 is cut in accordance with the position P'. Then, as shown by the arrow in FIG. 4B, if the release sheet 13 overlapping the back side of the base cloth 11 is removed,
The construction of one river of the roofing material is completed.

After removing the release sheet 13 overlapping the back side of the base cloth 11, the adhesive 14 remains on the back side of the base cloth, but may be removed or left as it is. That is, since the thickness of the adhesive 14 itself is extremely thin (1 mm or less), it does not hinder the subsequent construction of the roofing material. However, if the adhesive 14 is left without being removed, soil, sand, fibers,
It is preferable to prevent the stickiness by attaching sawdust, cloth, non-woven fabric, or the like.

Further, the roof underlaying material of the present invention is applied to a base plate in a state of being pulled and loosened while applying a certain tension, so that it can be easily positioned, and can be installed in a direction perpendicular to the inclination of the sloped roof. Even if it does, there is no problem that the roll slips on the sloping roof and cannot be stuck straight.

In this way, the above operation is repeated, and if the roof underlaying material is gradually overlapped with Futagawa and Mikawa, the entire area of the roof (field board) can be easily and efficiently covered. Moreover, it can be beautifully finished.

It should be noted that one or more sheets of the underlaying material of the present application may be enclosed in a package with a double-sided adhesive member (not shown) as an accessory. That is, as described above, during the construction of the roofing material, after the construction, when the roofing material still remains in the roll, using the attached adhesive member,
If the release sheet is adhered to the roll side facing the release sheet, it can be used again as the roof underlaying material of the present invention in the same manner as described above.

[0027]

As described above, the roof underlaying material according to the present invention has a waterproof / self-adhesive layer having a release sheet attached thereto, wound in a roll shape with the release sheet side inward, and a release sheet at the end of the winding. Since this is characterized in that it is adhered to the roll side facing it, a part of the release sheet at the end of the roll is peeled off to expose the waterproof and self-adhesive layer, and the tip is pasted on a base plate, When pasted in sequence while being rewound, the peeling sheet is naturally peeled off with a delay of one turn, overlapping the back side, making it easy to treat the peeling sheet and at the same time making roofing and underlaying material easier and more efficient It has an excellent effect that it can be performed well.

Further, in the roof underlaying material according to the second aspect of the present invention, since the release sheet is a transparent or translucent material, it is stuck on a field board while unrolling a roll. When going, even if the release sheet overlaps on the back side with a delay of one round, both edges of the roofing material can be seen through, and an excellent effect that the construction of the roofing material can be performed while confirming.

Further, the roof underlaying material according to the third aspect of the present invention is characterized in that an adhesive member for bonding the release sheet and a roll side facing the release sheet is attached. If the roof underlay material remains on the rolls due to the previous construction, use the attached adhesive member to attach the release sheet at the beginning of the roll to the roll facing it, so that the remaining rolls will also be covered by this roof It has an excellent effect that it can be used in exactly the same way as a roofing material.
