Abstract

(57) [Problem] To provide a roofing material and a roof structure which can obtain good assembling workability and have excellent strength and durability. SOLUTION: A snow stopper 18 has a cross-sectional shape curved and formed in a substantially V shape or a substantially U shape. For this reason, it has high strength and does not deform even if it is trampled during work. In addition, deformation due to snow pressure and the like are similarly well prevented. Further, since the snow stopper 18 does not have a pointed shape such as a triangular cross section, rusting or the like due to damage to the sharply bent portion is favorably reduced, corrosion resistance is improved, and processing is impossible. And strength and durability are improved.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a roofing material and a roof structure using the same, and more particularly to an improvement of a roofing material having a snowfall prevention function.

[0002]

[Problems to be solved by the prior art and the invention]

 As a conventional roofing material having a snowfall preventing function, there is a roofing material disclosed in Japanese Utility Model Laid-Open No. 3-90723, for example. According to this, in the direction substantially perpendicular to the inclination direction of the roof, the ridge for a snow stopper having an inverted L-shaped cross section is formed in a fold shape. However, according to this conventional technique, first, when assembling the roofing material, the rising portion hinders the scaffolding, and when it is stepped on, it is pushed down. In addition, even when there is a large amount of snow, the inverted L-shaped rising part may be pushed down by snow pressure. Then, it is not always possible to obtain a satisfactory snowfall prevention function. Further, an acute angle portion such as a rising portion is not preferable in terms of not only the strength but also the durability such as the progress of corrosion.

The present invention focuses on the above points, and it is an object of the present invention to provide a roofing material and a roof structure which can obtain good assembling workability and have excellent strength and durability. It is assumed that.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a roofing material according to the present invention is a roofing material in which a snow stopper having a slope for snow protection is continuously formed in a direction substantially orthogonal to the inclination direction of the roof, The snow stopper is formed to be curved and protruded. According to one of the main modes, the snow stopper is formed such that the cross section of the roof in the inclined direction is substantially V-shaped or substantially U-shaped. According to another aspect, a connection portion that can be fitted into each other is formed on the upper side and the lower side when viewed from the inclination direction of the roof. According to still another aspect, the projection that comes into contact when the coupling portion is coupled is formed in a direction substantially orthogonal to the inclination direction of the roof. According to still another aspect, a step is formed in the connecting portion as an inclined surface for snow stopping. According to still another embodiment, the slope for snow stopping is formed so as to be substantially horizontal when it is attached to a roof. The roof structure of the present invention is characterized in that any one of the above-mentioned roofing materials is laid continuously in parallel in the inclination direction of the roof.

[0005]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described in detail. FIG. 1 shows an end surface shape of the roofing material of the present embodiment. FIG. 2 is a perspective view showing a part thereof. In these figures, the roofing material 10 is for so-called roofing, and is manufactured by forming a long iron plate with a sheet metal forming machine (not shown).

At the lower position in the direction of inclination when attached to the roof, the edge is bent to the back side in a substantially U-shaped cross section, thereby forming the lower connecting portion 12. The snow slides on the roofing material 10 in the direction of arrow FA in FIG. The lower connecting portion 12 is connected to the base 16 via the inclined portion 14. Near the center of the inclined portion 14, a snow stopper 18 is formed so as to protrude toward the front side. The snow stopper 18 has a substantially V-shaped or U-shaped cross section, and is curved from the inclined portion 14. Further, at the upper position when the device is mounted on the roof, the edge portion is bent to the front side so as to have a cross-sectional shape that can be fitted into the lower coupling portion 12, thereby forming the upper coupling portion 20. A projection 22 is formed on the top of the upper coupling portion 20.

As an example of the dimensions, a long iron plate for a roof having a thickness of, for example, about 0.35 mm to 0.40 mm is used as the iron plate. The height L1 of the lower connecting portion 12 is 15 mm and the width L2 is 28 mm. The length of the inclined portion 14 is 81 mm, and the length of the base 16 is 102 mm. The width M1 of the snow stopper 18 is 12 mm and the height is 15 mm. The height N1 of the upper connecting portion 20 is 18 mm and the width N2 is 19 mm. Further, the total length of the roofing material 10 is 253 mm.

FIG. 3 shows a state in which the above-mentioned roofing material 10 is attached to a roof. As shown in the figure, the above-mentioned roofing material 10 is laid on a field board 30 via a roofing material 32 if necessary. The roofing material 10 is laid such that the lower connecting portion 12 is located below the roof and the upper connecting portion 20 is located above the roof, and the snow stopper 18 is substantially perpendicular to the inclination direction of the roof. Then, as shown by an arrow FB, the lower joint 12A of the upper roof material 10B is laid in order so that the lower joint 12B of the upper roof material 10B is fitted to the upper joint 20A of the lower roof material 10A so that the unevenness fits. Then, the projection 22A of the upper coupling portion 20A comes into contact with the lower coupling portion 12B, so that both are well coupled. In addition, intrusion of rainwater will be prevented.

Next, the operation of the roof structure of the present embodiment assembled as described above will be described. As described above, the snow stopper 18 has a cross-sectional shape curved and formed in a substantially V shape or a substantially U shape. For this reason, the strength is higher than that of the above-mentioned background art, and it is not deformed even if it is stepped on during work. Also, deformation due to snow pressure is similarly well prevented. Further, the snow stopper 18 does not have a sharp cross section such as a triangle, but has a smoothly continuous cross section. As a result, rust and the like due to damage to the sharp corners are reduced satisfactorily, the corrosion resistance is improved, the processing is easy, and the strength and durability are improved.

Next, another embodiment of the present invention will be described. First, the roofing material 50 shown in FIG. 4 is different from the above-described embodiment in that the inclined portion is eliminated to form a step 52 in the lower connecting portion 12 and the snow stopper 54 is connected to the lower connecting portion 12 by the upper connecting portion. It is formed almost in the middle of the part 20. According to this example, snow stops at not only the snow stopper 54 but also the step 52 of the connecting portion, and the snow stopping effect can be improved.

The roofing material 60 shown in FIG. 5 is such that the step of the connecting portion and the inclined surface of the snow stopper in the embodiment of FIG. 4 are substantially horizontal. That is, the step 62 of the lower connecting portion 12 and the snow-side slope surface 66 of the snow-stop portion 64 are formed so as to be substantially horizontal when assembled to the roof. The angle θ between the snow stop surface and the vertical direction is often set to 90 degrees or less in order to enhance the snowfall prevention effect. It is as pointed out in the above-mentioned prior art that rainwater accumulates in the recessed portion when doing so. Dust and dust may also stay. However, according to this embodiment, the snow slope on the snow stop side is substantially horizontal, so that rainwater flows without stagnation. For this reason, dust and the like also flow, which is preferable from the viewpoint of building aesthetics and hygiene. Since the snow stopper is provided by the step 62 of the lower connecting portion 12 and the snow stopper 64, a sufficient snow fall prevention effect can be obtained as a whole.

The present invention has many embodiments, and various modifications can be made based on the above disclosure. For example, the following is also included. (1) The above dimensions and shapes are merely examples, and may be changed as needed. (2) In addition, the design can be changed as appropriate within a range where the same action is achieved, such as the shape of the joint.

(1) Since the snow stopper is formed to be curved, rusting and the like due to damage to the sharply bent part are well prevented, corrosion resistance is improved, and processing is easy, strength and durability are improved. improves. Workability during assembly is also good. (2) Since a step is formed at the joint, the snow stopping effect can be improved. (3) Since the snow slope is formed in a substantially horizontal direction, accumulation of rainwater and dust is prevented, and the sanitary and aesthetic appearance is not impaired.
