Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roofing material and a method for constructing a roofing material, and more particularly, to simultaneously and integrally satisfy a waterproof function, a protection function, and a makeup function.
The present invention relates to a roofing material that simultaneously and integrally satisfies a makeup function and a heat insulating / soundproofing function, and a method of constructing a roofing material.

[0002]

2. Description of the Related Art <Metal Sheet Roofing Material> FIG. 16 is a perspective view including a partial cross section of a single-roofed roof as an example of roofing work using a conventional metal sheet roofing material. Figure 1
As shown in FIG. 6, a single-roofed roof such as a conventional general house is provided with an asphalt roofing 10 on a base plate 101.
2 and heat insulation material (not shown)
From 3 on, a metal roofing plate (roofing material) 104 is nailed and fixed to the base plate 101 with a nail 106 at a portion of a hook 105, and the roofing is sequentially performed. Reference numeral 107 denotes a drain board, and reference numeral 108 denotes a keraba drain board.

[0003] The roofing plate 104 has a rectangular shape, and has a first horizontal joint portion 104a bent to the back side at the lower side in the longitudinal direction,
Second lateral joint portion 104 bent to the front side in the longitudinal direction upper side
b. In addition, it has a first vertical joint portion 104c bent to the front side on the right side in the short direction, and a second vertical joint portion (not shown) bent to the back side on the left side in the short direction. All of these joints are "kohaze joints"
It is.

[0004] By the way, in the conventional construction method, it is necessary to perform waterproofing work on the groundwork before performing the roof work, and each work was completely independent. Here, the purpose of the waterproofing work is to ensure a waterproof function to prevent rain leakage, and the purpose of the roofing work is a makeup function to prevent the appearance of rain and protect the waterproof layer as well as to give an aesthetic appearance (protection and makeup function). .
When performing the roofing work, holes are made in the waterproof layer completed by the waterproofing work, and anchor screws, nails, and the like are driven in to fix the metal sheet roof material.

<Slate Roofing Material> Slate roofing materials, cement roofing materials, and the like are typical roofing materials other than metal sheet roofing materials. Since the slate roofing material or the like is made thin for the purpose of weight reduction, it tends to crack, become brittle, and easily crack due to aging. In particular, it cannot withstand the movement of buildings and vibrations such as earthquakes, and cracks are likely to occur in places where the movement concentrates. Also, if a worker climbs the roof during roof inspection or the like, it cannot withstand a point load. Cracks easily occur in weak areas. It should be noted that anchor screws and nails are also used in roofing work such as slate roofing material, and waterproofing work and roofing work are also performed independently in construction work such as slate roofing material.

[0006]

However, if the waterproofing work and the roofing work are performed independently as described above, holes are formed in the waterproof layer once completed, so that the waterproof function becomes insufficient. As a result, there is a risk that rain will leak from the roof due to aging. In particular, as described above, the slate roofing material is susceptible to cracks and the like in the material itself, and the insufficient waterproof function accompanying the roofing work overlaps with the slate roofing material. In addition, if the waterproofing work and the roofing work are independent as in the conventional construction method, the construction costs related to the roof tend to increase, and the construction period tends to be long.

Further, as shown in FIG. 17, a gap is formed between the nail 106 and the base plate 101 / asphalt roofing 102 due to aging, salt damage, etc.
Rainwater or the like may leak into the attic from a nail hole or the like used for fixing through a water intrusion path indicated by B. In addition, since the conventional metal sheet roofing material has many joints, there are many rain leaks from the joints. The tendency of the metal plate roofing material and the slate roofing material to leak rain is remarkable particularly at a portion where the roof gradient is gentle, a ridge portion, a valley portion, a curved surface portion, an upper end portion, and the like. Also, metal sheet roofing has the disadvantage that it absorbs solar heat in the summer and is thick inside the room, and in the winter it emits indoor temperature and is cold and has no heat insulation. The disadvantage is that the soundproofing effect is low.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a roofing material and a method for constructing a roofing material which simultaneously and integrally satisfy a complete waterproof function and a protective and decorative function. Also,
It is another object of the present invention to provide a roofing material and a method for constructing a roofing material that simultaneously and integrally satisfy a complete waterproof function, a protection / makeup function, and a heat insulation / soundproof function.

[0009]

In order to solve the above problems, the present invention is characterized in that a waterproof / functional sheet is attached to one surface of a protective / decorative function plate. Further, a self-adhesive functional material is provided on the surface of the waterproof functional sheet facing the base. In addition, a roofing material characterized in that a waterproofing functional sheet and a heat insulating functional plate are attached to one surface of a protective / decorative functional plate. In addition, a self-adhesive material is provided on the surface of one of the waterproof function sheet and the heat insulation function plate facing the base.

Further, the waterproof function sheet, or the waterproof function sheet and the heat insulation function plate, are configured to be larger than the protection / decoration function plate, and are self-attached to the protection / decoration function plate side in the enlarged portion. It is characterized by having a functional material. Further, a swelling preventing member is attached to a surface of the waterproof functional sheet, or one of the waterproof functional sheet and the heat insulating functional plate, which faces a base. Further, the roofing material is characterized in that the adjacent roofing material is hooked by a hooking means.

[0011] Further, the hooking means is characterized in that the waterproof sheet overlaps and the protective / decorative function plate is a knot splicing means. Further, the hookable means includes a hook. Further, the roofing material according to any one of claims 1 to 8 is a roofing material for single-story roofing, and the first-stage roofing material that is firstly laid in the horizontal direction is fixed to the ground with nails. Then, the waterproof function sheet of the next-stage roofing material, which is then roofed in the horizontal direction, is roofed so as to cover the nails of the first-stage roof.

By doing so, for example, FIG.
As shown in (A) to (C), a waterproof functional sheet (the waterproof sheet portion 2) is provided on one surface of the protective / decorative functional plate (metal plate 11).
0) is attached with a self-adhesive functional material (adhesive, adhesive, etc.), and the self-adhesive functional material (adhesive layer 22b)
To form Further, the waterproof sheet portion 20 includes an overlapping portion 20a larger than the metal plate 11, and a self-adhesive function material is formed on the overlapping portion 20a to integrally form the roofing material YY1.
This single-piece roofing material YY1 is single-roofed, for example, as shown in FIG. At the time of this roofing work, adjacent roofing materials YY completely cover adjacent portions with a waterproof sheet portion, and, for example, as shown in FIGS. 2 (A) and 2 (B).
The adjacent portion of the adjacent roofing material YY is completely fixed to the groundwork (field board 101) by means of hooks (hangers 32, nails 31).

Therefore, since the roofing material YY1 is integrally formed, the waterproofing work and the protection / makeup work can be achieved at the same time, and the construction period can be shortened and the cost of the roof-related work can be reduced. Also, the adjacent roofing material YY
Each of them has a completely waterproof function and is completely fixed to the groundwork, so it can withstand strong winds, etc. Also, even if the building moves due to an earthquake etc., the roofing material is fixed to the groundwork independently for each sheet Absorbs the movement of the groundwork and the movement of heat,
The decorative functional plate and the waterproof functional sheet are not broken.

[0014]

Then, a back adhesive layer 22b and a back release paper 23b are sequentially formed and attached. As the waterproof sheet used for the waterproof sheet portion 20, a synthetic rubber sheet having a pressure-sensitive adhesive layer and a rubber asphalt-based sheet are preferable, and specifically, GAMRON MG Base B manufactured by Tajima Roofing Co., Ltd. is preferable. Note that a modified asphalt layer may be used instead of the synthetic rubber layer 21.

(2) How to roof the roof Next, how to roof the roof (single-letter roofing) will be described with reference to FIGS. 2 (A), 2 (B) and 3. 2A is a side cross-sectional view after the roofing work is completed, FIG. 2B is an enlarged cross-sectional view of the joint portion, and FIG. 3 is a plan view of the roofing work. Note that FIG.
In the description of (A) and (B), it is assumed that the construction of the ground board 101, the eaves arabesque 103, and the like have already been completed.

First, as shown in FIGS. 2 (A), 2 (B) and 3, the first roofing material YH1 from which the back release paper 23b (FIG. 1 (B)) has been peeled in advance, Affixed sideways in a predetermined direction, the stainless steel nail 31
(FIG. 2 (B)) and through the nail hole 11b,
And fix it. After fixing, L-shaped front release paper 23
a (FIG. 1A) is peeled off to expose the L-shaped front adhesive layer 22a.

Next, the back release paper 23b was peeled off in advance 2
The first roofing material YH is placed on the left side of the first roofing material YH2.
After being aligned with No. 1, it is affixed to the roofing material YH1 and the ground board 101 so as to cover the notch 11c (FIG. 1A). By this attachment, the overlapping portion of the right end side of the roofing material YH1 and the left end side of the roofing material YH2 is completely sealed by the adhesive layer, so that rainwater or the like cannot reach the field board 101. Therefore, it does not cause rain leakage to the attic (not shown). That is, it is possible to simultaneously achieve the waterproof function and the protection and makeup function only with the roofing material YY of this embodiment.

The above steps are sequentially repeated to finish roofing the first-stage roofing materials YH1 and YH2. Further, the hooks 32 are provided at the nail holes 11b of the first-stage roofing materials YH1 and YH2.
Are sequentially fixed with nails 31 and the second-stage roofing material YH11, Y
A preparation is made to engage H12 ~ (the engaging mechanisms are engaged with each other). As described above, all the first-stage roofing is completed.

Next, the back release paper 23b was peeled off beforehand.
The horizontal joint 11a (Y
H11) to the first stage / first roofing material YH1
2 and firmly affixed to the base plate 101 at a predetermined position. By this hooking and sticking, the upper end side of the roofing material YH1 and the lower end side of the roofing material YH11 are completely sealed by the adhesive layer (FIG. 2B), so that rainwater and the like cannot reach the field board 101. Next, the horizontal joint portion 1 of the second / second roofing material YH12 from which the back release paper 23b has been peeled off in advance.
1a (YH11) is replaced with the first-stage / first roofing material YH1
And the first-stage / second roofing material YH2 are firmly engaged with each other, and affixed to the base plate 101 at predetermined positions.

As described above, the roofing material YY adjacent in the lateral direction is used.
1 are completely sealed by an adhesive layer, roofing materials adjacent in the longitudinal direction are hung and sealed, and are sealed and blocked by a left end 21b (FIG. 2B) of the synthetic rubber layer 21; The suspension 32 is completely covered with the synthetic rubber layer 21, so that rainwater or the like cannot reach the base plate 101. Therefore, it does not cause rain leakage to the attic (not shown). In addition, since the adjacent roofing material is completely fixed by the hanging member / transverse joint portion and the adhesive layer at the same time, it can withstand strong winds and the like for many months, so that no maintenance is required. Thereafter, the roofing material YY1 in the second stage is sequentially roofed, and the roofing material YH is further roofed in the third, fourth, etc., and then the roofing is completed (FIGS. 2A and 3). .

According to this embodiment, the following effects can be obtained. Since the adjacent roofing material is completely fixed by the hanging member / transverse joint and the adhesive layer, it can withstand strong winds and the like for many months, so that no maintenance is required. Since the metal plate portion and the waterproof sheet portion are integrally formed, the waterproof sheet portion follows the movement of the base, so that the metal plate portion is not broken. Since the metal plate portions are nailed and fixed to the base independently of each other, the movement of the base and the thermal expansion and contraction of the metal plate are absorbed, and no distortion occurs in the metal plate.

As shown in FIGS. 4A and 4B,
A clasp type suspender or an embedded reinforcing mesh may be used.
This has the effect of increasing the strength of a heat insulating plate such as an inorganic hard foam plate by incorporating an embedded reinforcing mesh, and preventing cracks and chipping. Also, the back adhesive layer 22b
It is good also as a type of roofing material which is not provided.

<Modification> This modification is a case where a "blowing prevention function" is added to the roofing material YY1 of the first embodiment.
That is, when the roofing material YY1 is exposed to direct sunlight, the air between the concrete surface and the roofing material YY1 expands, and swelling occurs between the concrete surface and the roofing material YY1. There is a possibility that the waterproof function is reduced. The present embodiment is a case where such a decrease in the waterproof function is prevented. FIG. 5A is a plan view, a longitudinal side view, and a lateral side view of a roofing material YY2 of this modification, and FIG. 5B is an enlarged sectional view of a waterproof sheet portion of the roofing material. The difference between the present modified example and the first embodiment is that a swelling prevention tape 24 which is an "swelling prevention member" with an adhesive is attached to the lower surface side of the waterproof sheet portion 20 in parallel at regular intervals in the form of vertical stripes. Points and
The point is that longitudinal joint portions 11d and 11e are formed in the longitudinal direction of the metal plate 11. As the swelling prevention tape 24, a rubber asphalt-based double-sided tape, a butyl rubber-based double-sided tape, and a synthetic resin-based film having excellent durability are preferable.

In this way, even if the air between the roofing material YY2 and the concrete surface or the like expands, water vapor and expanded air from the foundation are discharged to the outside from the gap between the swelling prevention tapes 24. The roofing material YY2 does not swell. In place of the swelling prevention tape 24, the swelling prevention tape (Japanese Patent Application No. 11-350818) previously filed by the applicant of the present application was used.
No., “A waterproof sheet type roofing material”) may be used.

(II) Second Embodiment This embodiment is a case of a roofing material YY3 which completely prevents invasion of water such as rain and is excellent in heat insulation, sound insulation and sound insulation. The difference from the example is that a heat insulating material 30 is added.

FIG. 8A is a plan view, a longitudinal side view, and a lateral side view of the roofing material YY4 of this embodiment, and FIG. 8B is an enlarged cross-sectional view of the waterproof sheet portion of the roofing material. FIGS. 9A and 9B are side sectional views after completion of the roofing work.

In the roofing material YY4, a hooking protrusion 11f and a hooking recess 11g are formed in the left and right vertical direction of the metal plate 11, and the hooking protrusion 11 of the roofing material YY4 adjacent to the hooking recess 11g is formed.
f. Further, the folded portion 20a is formed along a substantially horizontal center line of the waterproof sheet portion 20. This modification is characterized in that it can be finished three-dimensionally with irregularities as a heat-insulating and waterproof type decorative roofing material, and various designs are possible.

In the case of roofing, as shown in FIG. 9 (B), a catch type suspender, an embedded type suspender, or an embedded type reinforcing mesh may be used.

<Second Modification> In this modification, one side of the metal plate 11 in the roofing material YY4 of the second embodiment is bent. FIGS. 10A and 10B are a plan view, a longitudinal side view, and a lateral direction side view of the roofing material YY4 of this embodiment, and FIG. 10C is a side sectional view after the roofing work is completed. In this case, the heat insulating material 3 is bent by the bending 11h.
Since the heat insulating material and the waterproof sheet portion 20 are covered, the heat insulating material and the waterproof sheet portion are not exposed, and the heat insulating material and the waterproof sheet portion are not damaged during transportation or construction.

(III) Third Embodiment In this embodiment, a waterproof sheet is attached to an asbestos slate. FIG. 11A is a plan view, a longitudinal side view, and a lateral side view of the roofing material YY3 of the present embodiment, and FIG. 11B is an enlarged cross-sectional view of the waterproof sheet portion of the roofing material.
