The present invention relates to a heat insulating shingle for horizontal roofing that can improve wind resistance and strength.

[0002]

2. Description of the Related Art Conventionally, as a roofing plate for horizontal roofing, a locking portion is formed on the side edge of the roof plate body in the eave direction and an engaging portion is formed on the side edge in the ridge direction. 59-10272
There is the one described in Japanese Patent Publication No. This conventional roofing shingle is mainly composed of a foam made of polyurethane or other material attached to the back surface of the shingle body via an adhesive or the like, for example, so that the heat insulation and sound deadening properties of the roofing shingle are reduced. Alternatively, the sound insulation is improved. This foam is not provided in the engaging portion. In addition, the shape of the inclined portion of the locking portion in the eaves side direction of this conventional roofing plate for horizontal roofing is such that the locking portion and the engaging portion of the adjacent roof plate are fitted after the roofing plate is constructed. In order to improve the strength of the part, it has a shape that is bent substantially at right angles to the surface of the shingle body.

[0003]

In this conventional roofing sheet for horizontal roofing, for example, an adhesive or the like is used to attach a foam to the back surface of the roofing sheet body. The plate manufacturing process was increasing. In addition, in this conventional roofing sheet for roofing, since the foam is not provided in the engagement portion as described above, the heat insulating property, sound deadening property, or sound insulating effect of the roof sheet after construction is weakened. .

Further, in the conventional roofing shingle for roofing, the shape of the inclined portion of the locking portion in the eaves direction has a shape which is bent substantially at a right angle to the surface of the shingle body. Although the strength improvement at the fitting part of the roof shingle is relatively good, there is a risk that the wind resistance may be directly received by the bent surface of the locking part and the roof shingle may be lifted up by the strong wind when the wind is strong. In addition, for example, drainage of rainwater or the like flowing down on the roof plate in rainy weather or the like becomes worse, and external dust and dust easily enter the gap of the fitting portion, so that dust accumulated in this gap For this reason, the roof plate was corroded and durability was reduced. Therefore, in order to solve these problems, it is conceivable to simply incline the inclined portion in the eaves direction of the locking portion in the roofing plate for horizontal roofing, but simply inclining downward in this way after construction There is a possibility that a new problem of lowering the strength of the fitting portion where the locking portion and the engaging portion are fitted may occur. The present invention has been made on the background of such a conventional technology, and reduces the number of manufacturing processes and heat insulation, noise reduction or sound insulation. It is an object of the present invention to provide a heat insulating shingle for horizontal roofing that can simultaneously improve strength, wind resistance, drainage, corrosion resistance, and durability.

At the time of construction, the folded portion is fitted into a lower fitting portion (a gap portion having a U-shaped cross section) 130 of the engaging portion 12.

Further, as shown in FIG. 2, the lower fitting portion 130 of the engaging portion 12 has a gap 13 between the locking portion 11 and the fitting portion 13 of the engaging portion 12 in the event of wind and rain.
In order to prevent rainwater from entering the attic due to the capillary phenomenon, a downward concave drainage space 121 is formed from 1. In addition, the projecting portion does not contact the back surface of the tip of the locking portion 11 to form a drainage empty portion 122. Further, by providing a step at the upper end portion of the projecting portion, a drainage empty portion 123 is formed. ing.

A rigid foam 20 is laminated on the back surface 10c of the shingle body 10. The rigid foam 20 improves the heat insulating property, sound-absorbing property, or sound-insulating property of the heat-insulating roofing sheet for horizontal roofing, and a fitting portion in which the engaging portion 11 and the engaging portion 12 are fitted after the construction. 13 is a member for improving the strength. As the material, for example, polyurethane foam, polyisocyanurate foam, phenol foam, polyethylene foam, polypropylene foam and the like can be used.

In this embodiment, the rigid foam 20
1, the entire area between the back surface 10c of the shingle body 10 and the back surface material 21, the inside 1 of the engagement portion 12, as shown in FIG.
The rigid foam 20 is completely filled between the entire area of 2a and a part of the back surface except for the back surface of the eave-direction inclined portion 11a of the locking portion 11 and the back material 21, and the inside 12a of the engaging portion 12 is completely filled. ing. In the present invention, a back material 21 is laminated on the back surface of the rigid foam 20 in order to substitute for a mold during molding of the rigid foam 20 and to protect the surface of the rigid foam 20 after production. As a material of the back material 21, for example, aluminum vapor-deposited paper, aluminum foil laminated paper, aluminum foil, steel foil, or the like can be used.

Further, the rigid foam 20 of this embodiment is:
The above-described hard foam is formed between the back surface member 21 and a part of the back surface except for the back surface 10c of the shingle body 10, the inside 12a of the engaging portion 12, and the back surface of the eave-direction inclined portion 11a of the locking portion 11. The body 20 is molded by integrally foaming and filling the material, but it is not always necessary to limit to this molding method. By forming the rigid foam body 20 integrally with the roof slab body 10 and the like in this manner, the number of manufacturing steps of the heat insulating shingle for horizontal roofing can be reduced.

Next, the operation of the heat insulating shingle for horizontal roofing according to the embodiment of the present invention will be described. First, as shown in FIG. 1, a locking portion 1 of heat insulating roofing sheets for horizontal roofing adjacent to each other on a roof.
1 and the engaging portion 12 are sequentially fitted and connected / constructed. At this time, since the rigid foam 20 is provided at least between the back surface 10c and the back surface member 21 of the roof slat body 10 and the inside 12a of the engaging portion 12, the heat insulating property and the sound deadening of the heat insulating shingle for horizontal roofing are provided. Performance or sound insulation can be improved. In particular, in this embodiment, as shown in FIG. 2, the rigid foam 20 is also provided on a part of the locking portion 11, so that the entire area of the fitting portion 13 between the locking portion 11 and the engaging portion 12 is provided. In this case, the rigid foam 20 is provided evenly.
In addition, a cold bridge hardly occurs, preventing dew condensation, and the heat insulation effect is further improved.

Further, as described above, the inside 12a of the engagement portion 12 is formed.
Is provided with the rigid foam 20, so that the strength of the fitting portion 13 in which the locking portion 11 and the engaging portion 12 are fitted after the construction can be improved. Furthermore, since the eaves-like inclined portion 11a of the locking portion 11 is inclined downward, the wind resistance is not directly received by the inclined surface of the locking portion 11 in a strong wind. The danger of the heat insulating roof shingle being lifted up by this strong wind is reduced, and the wind resistance of the roof shingle is improved, and for example, the rainwater flowing down on the roof shingle during rainy weather etc. has less steps and flows smoothly because it drains smoothly. In addition, it becomes difficult for external dust and dirt to enter the gap between the fitting portions, and therefore, the corrosion resistance and durability of the roof slab can be improved.

The eave-direction inclined portion 11a of the locking portion 11
Is bent in the direction of the eaves, and at the time of construction, the folded portion is fitted into the lower fitting portion (a void portion having a U-shaped cross section) 130 of the engaging portion 12. After the construction, even if rainwater tries to enter the attic due to the capillary phenomenon from the gap 131 between the engaging portion 11 and the engaging portion 13 of the engaging portion 12 also shown in FIG. 12
In the fitting portion 13 with the locking portion 11, the downward fitting drainage empty portion 121 is formed in the lower fitting portion 130 of the engaging portion 12, so that rainwater can enter the attic. Can be prevented.

Further, even if rainwater intrudes into the interior due to wind pressure or the like, the rainwater is caught by the drainage empty space 122 and / or the drainage empty space 123, so that it is possible to completely prevent rainwater from entering the attic. it can. By providing two or more empty portions for draining water on the back surface side of the locking portion, it is possible to more reliably prevent rainwater from entering the attic. In the present invention, the position where the drainage vacancy other than the drainage vacant space 121 is provided is not particularly limited. However, providing at least one of the drainage vacancies on the back side of the distal end of the locking portion 11 like the drainage vacant space 122 may be performed. It is particularly preferred for preventing rainwater from entering the attic. That is, when the heat insulating roofing sheet for horizontal roofing of the present invention is constructed on a sloped roofing sheet construction surface, the tip of the locking portion 11 is located at the lowest position in the heat insulating roofing sheet for horizontal roofing, and the drainage space is not used. Part 122
This is because the rainwater caught in the water is settled in the drainage space 122 and hardly penetrates into the attic located above the location.

Further, by providing a drainage space in the depth direction of the drainage space 122 like the drainage space 123, more rainwater can be caught by these drainage spaces. Become. Here, empty space 1 for draining
The step of the protruding portion forming 23 also has a function of locking the suspender when the suspender method is used for the construction of the heat insulating shingle for horizontal roofing. At that time, the drainage empty space 123 also serves as a space for installing the suspender.

Also, in this embodiment, these locking portions 11
Also, since the engaging portion 12 has the same shape as shown in FIG. 2, the step of the fitting portion 13 looks visually large after construction, and a three-dimensional effect can be obtained as compared with a conventional roof plate. Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and any change in design within a scope that does not change the gist is included in the present invention. For example, in the embodiments, the heat insulating roof sheet for horizontal roofing for general houses is taken as an example, but the heat insulating roof sheet for horizontal roofing for any building is not limited thereto.

[0024]

According to the heat insulating roofing sheet for horizontal roofing of the present invention, the inclined portion in the eaves direction of the locking portion is inclined downward as described above, and at least the portion between the back surface of the roof plate body and the backing material and the engaging portion are provided. Since the rigid foam is integrally provided inside the housing, the manufacturing process is reduced, and the heat insulation, sound-absorbing or sound-insulating properties are reduced, and the strength and wind resistance of the fitting portion where the locking portion and the engaging portion are fitted after the construction is completed. The effect of improving drainage, corrosion resistance and durability at the same time can be obtained. Further, in the heat insulating shingle for horizontal roofing of the present invention, since a drainage space is formed in the fitting portion between the locking portion and the engaging portion, rainwater flows from the gap between the fitting portions by the attic by capillary action. Can be prevented from invading.
