Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backing material interposed between a roof base and a metal shingle for a stepped roof that is stepped from an eave to a ridge.

[0002]

2. Description of the Related Art A roof structure in which a metal shingle is stepped is constructed in such a manner that a gap is formed for each step between a roof foundation in which asphalt roofing is laid on a base plate and a metal shingle. Has become. Therefore, for example, when a worker performing a roofing operation rides on a roofed metal roofing plate, the weight of the metal roofing plate may cause the metal roofing plate to be dented, and the aesthetic appearance of the roof may be impaired.

By the way, recently, a metal roof plate in which a heat insulating material made of foamed polyethylene or other synthetic resin is adhered to the back surface with an adhesive is gradually spreading, and among them, the thickness of the heat insulating material is limited to the roof. As the same level as the height of the gap between the base and the metal shingle, there is also provided one that has been devised so as not to be dented even when the operator rides on the metal shingle as described above. .

[0004]

However, it can be generally said that a metal roof plate to which a heat insulating material is adhered is mainly sprayed or applied with an adhesive on the back surface of the metal roof plate. Because it is pasted, for example, when the roof is changed or the house itself is dismantled, the insulating material pasted with adhesive is separated from the metal roof plate,
It is difficult to separate each as separate waste,
There is no help for disposal. And, as described above, the metal roof slab to which the heat insulating material with the same thickness as the height of the gap is stuck, the amount and size of the heat insulating material increases by that much, so the total amount of waste that cannot be disposed of Inevitably increase. Although the use of thermal insulation in the attic has certain attractive benefits in terms of improving the living environment, the present inventor will continue to remain in the attic until decades later and will not be able to dispose of it as waste in the future. The present invention has been accomplished in the hope that the heritage will not be preserved in future descendants as much as possible.

That is, an object of the present invention is to prevent deformation of a metal shingle without using a heat insulating material having the same height as a gap between a roof base and a metal shingle as in the prior art. It is to provide a member. In addition, the present invention reduces the total amount of waste that is difficult to separate because the metal material and the heat insulating material are integrated when the metal shingle is replaced or dismantled, even when using the heat insulating material for the attic. An object of the present invention is to provide a technology that can be minimized.

[0006]

In order to achieve this object, the present invention provides a back surface facing a roof base and a front surface facing a back surface of a metal roof shingle that is stepped from an eave to a ridge of a roof structure. A metal roof shingle having a plurality of upwardly or downwardly projecting support portions that gives a member height corresponding to the height of a gap formed between the roof base and the back surface of the metal shingle on a sheet material having It provides backup materials.

According to this, the plate member is provided with an upwardly or downwardly projecting support portion, and the support portion is a member corresponding to the height of a gap formed between the roof base and the back surface of the metal roof plate. Because of the height that gives the height, even if a load acts on the metal shingle from above, the support part intervenes in the gap between the roof basement and the metal shingle in the height direction, so that the metal shingle can be It can be prevented from being dented. Moreover, since the supporting portion interposed in the height direction forms an air passage between the plate material and the back surface of the roof base or the metal roof plate, sufficient air permeability can be secured so that air does not stay in the attic. Further, since the plate member is provided with a plurality of such support portions, the load acting on the metal roof plate from above can be dispersed and supported by each support portion, so that a strong support force can be exhibited. The “member height” means that the backup material itself has a height corresponding to the height of the gap between the roof foundation and the back surface of the metal shingle. Therefore, the height of the support portion itself is determined by the relative relationship between the plate thickness of the plate material (when a heat insulating material is provided, the plate thickness of the plate material and the thickness of the heat insulating material).

[0008] The backup material of the present invention can be implemented in various forms. For example, as one type, separate members “plate material (for example, steel plate, wood plate, plastic plate, paper-like plate material, etc.)” and “support portion (for example, metal, wooden, plastic, etc. bar material)” It can be configured integrally via a joining means (for example, adhesion, welding, riveting, screwing, etc.). A pair of connecting structures (for example, a connecting structure using a dovetail and a dovetail groove) formed in the “plate material” and the “support portion” may be integrated without using such a joining means.

[0009] As another type, a steel plate is used as the "plate material", and a sheet metal working is performed on the steel plate to form a backup material having a support portion. In the present invention, as such a back-up material, a metal plate having a back surface facing the roof base and a front surface facing the back surface of a metal roof shingled from the eaves to the ridge of the roof structure is provided with a roof. A downward bead-shaped support portion which gives a member height corresponding to the height of the gap formed between the base and the back surface of the metal roof plate is bent. Since this back-up material can be formed by bending the plate and a metal plate, the support and the support are not separate members but are integrated, and therefore the manufacture is relatively easy and the cost is advantageous. .

[0010] In the above-mentioned backup material, supporting portions are formed on the ridge side and the eave side of the plate material, respectively, and the height of the supporting portion located on the eave side is made higher than the supporting portion located on the ridge side. preferable. In other words, the eaves-side support is higher than the ridge-side support according to the change in the height of the gap between the roof base and the metal shingle seen on the stepped roof. Thus, the load acting on the metal roof plate can be reliably supported.

[0011] Further, regarding the above backup material,
The heat insulating material may be attached to the surface of the plate material in a state of being in contact with the back surface of the metal roof plate. In addition, the above-mentioned backup material can be configured as a heat-insulating material attached to the back surface of the plate material.

According to the backup material to which the heat insulating material is attached, it is not necessary to first adhere the heat insulating material to the back surface of the metal roof plate. As a result, a conventional metal roofing plate with heat insulating material attached to almost the entire back surface, or a conventional heat insulating material with a thickness of about the gap between the roof base and the back surface of the metal roof plate are attached. Compared with the metal roof slab, the amount of the heat insulating material integrated with the metal material can be greatly reduced. Therefore, it is possible to reduce the total amount of waste that is difficult to separate when the roof is replaced or dismantled. In addition, according to the backup material in which the heat insulating material is attached to the surface of the plate material, the heat insulating material is attached in contact with the back surface of the metal roof plate, and therefore, exhibits the following function with respect to the metal roof plate. In other words, even if the rain hits the metal roof plate during rainy weather, the heat insulation material can absorb the rain noise to a small extent. In addition, even if an instantaneous load is applied to the metal shingle such as when the worker accidentally rides on the metal shingle when performing the roofing work, the instantaneous load is applied to the metal roof shingle. Can be.
On the other hand, even if a constant load such as a TV antenna or a snow cover in winter is applied to the metal shingle, the heat insulating material deforms to follow the slight deflection of the metal shingle, Since the adhesiveness with the back surface of the attic is maintained, a high heat insulating effect can be exhibited, and the occurrence of dew condensation on the attic can also be prevented. In addition, because the heat insulating material comes into contact with the back of the metal shingle, it gives the roof of the metal shingle a "tension".
The overall appearance of the roof will be uniform and beautiful.

Here, as a means for attaching the heat insulating material to the surface portion of the plate material, it can be most easily fixed by a chemical means such as an adhesive or a glue, but the following means are used. In the future, the plate material and the heat insulating material may be fixed so that they can be completely separated. That is, as for the backup material provided with the heat insulating material, the heat insulating material can be attached to the surface of the plate by being sandwiched by a locking portion formed by folding the end of the plate upward.
According to this, for example, the heat insulating material can be fixed to the plate material only by bending the metal material such as a steel plate, so that a chemical means such as an adhesive is unnecessary, and the heat insulating material is separated. All you have to do is pull the insulation. Further, in order to fix the heat insulating material to the plate material at a position other than the end of the plate material, for example, a metal plate material is cut and raised to form a locking piece, and this is pressed down against the heat insulating material to be fixed to the plate material. You can also In addition to this, a flexible heat insulating material is pushed into the inside of a supporting portion formed by bending a metal plate material,
In this state, the support portion may be crushed to fix the heat insulating material by sandwiching it from the left and right directions.

Regarding the above backup material,
It is preferable that an engaging portion bent in a crank shape is formed at the eave-side end portion of the plate material so as to be slidably engageable between the ridge-side end portion of the metal roof plate located on the eave side and the roof foundation. According to this backup material, the backup material can be correctly attached without displacement during construction.

According to the roof structure in which the above-mentioned backup material is attached to the gap between the roof foundation and the metal shingle, the roof material can exhibit the above-mentioned function and effect. it can.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. Note that components having the same functions in the respective embodiments are denoted by the same reference numerals, and redundant description is omitted.

FIG. 1 is an external perspective view showing a backup material 1 for a metal roofing plate according to an embodiment of the present invention. This backup material 1 is formed by bending a steel plate as a “plate material”, and serves as a “supporting portion” extending in a direction orthogonal to the roof inclination direction (ridge direction x ₁ , eaves direction x ₂ ). An eaves-side bead 2 and a ridge-side bead 3 also serving as a "supporting portion" are bent downward. The eaves-side bead 2 is higher than the ridge-side bead 3. This is because, as shown in FIG. 2, the height h of the gap s between the metal roof plate 5 and the roof base 6 is highest on the eaves side, and gradually decreases toward the ridge side. This is to ensure that the load acting on the metal roof plate 5 can be supported. In addition, 1a is a front surface portion facing the back surface of the metal roof plate 5, and 1b is a back surface portion facing the roof base 6, and the front surface portion 1a is mainly made of a flexible sheet-like foamed polyethylene. (See FIG. 2).

FIG. 2 shows the construction of the backup material 1. This roof structure is formed by stepping a long metal roof plate 5 from the eave to the ridge. In particular,
After the metal roof plate 5 on the eaves side is laid on the roof base 6 on which the asphalt roofing 6b is laid on the base plate 6a, the eaves bead 2 is brought into contact with the ridge side end 5a, and the roof base 6
Place on top of. At this time, the backup material 1 is not fixed to the roof base 6 with nails or the like, but the eave-side bead 2 formed in the longitudinal direction of the backup material 1 is formed on the ridge side end formed in the longitudinal direction of the metal roof plate 5. Since it is in contact with the portion 5a in the length direction, there is no possibility that the mounting state of the backup material 1 is shifted. Then, the metal roof plate 5 is roofed thereon, and at this time, the metal roof plate 5 is attached with its back surface in contact with the heat insulating material 7.

The backup material 1 at the next stage may be mounted similarly using the same material as the backup material 1 in FIG. 1, but in FIG. 2, the eaves side edge along the longitudinal direction of the backup material 1 faces downward. Is formed at the ridge side end 5a of the metal shingle 5 at the preceding stage.
And asphalt roofing 6b. By doing so, the backup material 1 can be securely attached to a predetermined position.

In the above-described backup material 1 and the roof structure using the same, for example, even when an operator rides on the metal roof plate 5, the gap s between the metal roof plate 5 and the roof foundation 6 is high. The eave-side bead 2 and the ridge-side bead 3 interposed in the height direction h can support the metal roof plate 5 so as not to be dented. Moreover, the back portion 1 of the backup material 1 is formed by the beads 2 and 3 interposed in the height direction h.
Since the gap s formed between b and the roof foundation 6 functions as an air passage, sufficient air permeability can be secured so that air does not stay in the attic. In addition, since it is not necessary to attach the heat insulating material 7 to the entire back surface of the metal roof plate 5, the amount of the heat insulating material integrated with the metal material can be greatly reduced, and the material is separated when the roof is replaced or dismantled. The total amount of waste that is difficult to treat can be reduced. Furthermore, since the heat insulating material 7 is attached in a state of being in contact with the back surface of the metal roof plate 5 in a pressing manner, it is possible to reduce (reduce) the rain sound generated in rainy weather. Further, even if an instantaneous load acts on the metal roof plate 5, the instantaneous impact can be buffered by the heat insulating material 7. On the other hand, even if a constant load such as an installation such as a TV antenna or snow cover in winter acts on the metal shingle,
Since the heat insulating material 7 is deformed to follow the slight bending of the metal roof plate 5 and the adhesion to the back surface of the metal roof plate 5 is maintained, a high heat insulating effect can be exhibited, and the occurrence of dew condensation on the attic can be prevented. . Further, since the heat insulating material 7 comes into contact with the back surface of the metal shingle 5 to give “tension” to the surface of the shingled metal shingle 5, the appearance of the entire roof is beautifully finished.

Next, a modified example of the above embodiment will be described. FIG. 3 shows that the heat insulating material 7 is replaced with the backup material 1 without using an adhesive.
It is an example of attaching to. That is, in this example, both the ridge side edge and the eaves edge along the length direction of the backup material 1 are bent upward as shown in FIG.
The heat insulating material 7 is attached by inverting the locking portion 1d and biting into the heat insulating material 7. In this example, no chemical fixing means such as an adhesive is used. Then, when separating the heat insulating material 7 from the backup material 1 may simply pull the heat insulating material 7 to the direction indicated by the arrow x _3. Then insulation 7
Can be easily removed from the locking portion 1d. Accordingly, it is possible to separate the backup material 1 which is a metal material from the heat insulating material 7. Although illustration is omitted,
For example, the heat insulating material 7 is pushed into the eaves-side bead 2 and the ridge-side bead 3 of the backup material 1 shown in FIGS. You can also attach it by holding it,
A triangular locking piece is cut and raised on the plate surface of the backup material 1, and the heat insulating material 7 is laid down and held down from above.
May be attached.

In the above embodiment, an example is shown in which two "supporting portions" of the eave-side bead 2 and the ridge-side bead 3 are provided. However, the number of "supporting portions" may be any number and the number of "supporting portions" may be any. The width may be wider or narrower. Alternatively, a vent may be formed in the backup material 1 through the front surface portion 1a and the back surface portion 1b to prevent dew condensation.

In the above-mentioned backup material 1, for example, as shown in FIG. 4, the plate material 1d, the eaves-side bead 2 as a "support portion", and the ridge-side bead 3 may be constituted by different members. In this case, as the plate 1e, the eave-side bead 2, and the ridge-side bead 3, a plate or a bar made of metal, wood, plastic, paper, or the like can be used. And glue these together,
The plate 1e and the eave-side bead 2 and the ridge-side bead 3 may be integrated by an arbitrary joining means such as welding, riveting, screwing, or the like by a connecting structure such as a dovetail and a dovetail groove. .

Further, the backup material 1 is turned upside down, ie, the eaves-side bead 2 and the ridge-side bead 3
The backing material 1 against the metal roof plate 5
The surface portion 1a or the heat insulating material 7 may be brought into contact with the roof base 6 and attached.

In the above-described embodiment, the backup material 1 has a substantially flat shape as an overall shape. However, the backup material 1 is formed into a mountain wave shape in which peaks and valleys are continuously formed in an acute angle or a curve in the width direction (the roof inclination direction). Alternatively, the top of the “mountain” may be brought into contact with the back surface of the metal roof plate 5, and the valley of the “mountain” may be brought into contact with the roof base as a “support”. In this case, in order to attach the heat insulating material, it is possible to form and attach the locking portion as shown in FIG. 3 to the end of the backup material.

In the above embodiment, an example is shown in which the asphalt roofing 6b is laid on the base plate 6a as the "roof foundation". "
Of course, the present invention can also be applied to the case of a reform in which a metal shingle is laid on the roof.

[0027]

According to the backing material for a metal shingle and the roof structure using the same according to the present invention, even if a load is applied to the metal shingle from above, the support portion is provided between the roof base and the metal shingle. The metal roof plate can be prevented from being dented by being interposed in the height direction. Moreover, since the supporting portion interposed in the height direction forms an air passage between the plate material and the back surface of the roof base or the metal roof plate, sufficient air permeability that air does not stay in the attic can be secured. Further, since the plate member is provided with a plurality of such support portions, the load acting on the metal roof plate from above can be dispersed and supported by each support portion, so that a strong support force can be exhibited.

Further, according to the backup material to which the heat insulating material is attached and the roof structure using the same, the heat insulating material does not need to be stuck to the back surface of the metal roof plate, and the heat insulating material is stuck to almost the entire back surface. Compared to conventional metal roofing shingles or conventional metal roofing shingles with heat insulating material with a thickness of about the gap between the roof base and the back of the metal shingle, The amount of used insulation can be significantly reduced. Therefore, it is possible to minimize the total amount of wastes that are difficult to separate at the time of roof replacement or dismantling. Furthermore, since the heat insulating material is attached in contact with the back surface of the metal roof plate, it is possible to absorb the rain noise generated when it rains. In addition, even if instantaneous and constant load acts on the metal roof shingle, the thermal insulation absorbs shock as a cushion,
Since the metal roof shingle is deformed following the slight deflection and the contact with the back surface of the metal roof shingle is ensured, a high heat insulating effect and a dew condensation preventing effect can be exhibited. In addition, since the heat insulating material presses against the back surface of the metal shingle to give "tension" to the surface of the shingled metal shingle, the appearance of the entire roof is beautifully finished.
