It is also possible to carry out partial construction using the roof hanger 12 having a structure that reinforces the structure, and the shape of the water return portion 2 and the falling portion 4 and the hook portion 5 of other roof plates are partially It goes without saying that these are included in the scope of the present invention.

Next, specific examples of the present invention will be described with reference to FIGS.
1st invention is the cross-sectional shape of the water return part 2, the latching | locking part 3, the falling part 4, the hook part 5, and the fixing | fixed part 6 in the surface material of the metal roof board 1, as shown in FIGS. In the case where a metal plate having a predetermined width is continuously formed in the longitudinal direction and the roof plate is overlapped on both end faces, the lower overlap portion 7 shown in FIGS. 1 and 4 and FIGS. 1 and 5 are used. In order to make the construction easier at the time of jointing, the fixing part 6 and a notch part 9 in which a part of the water return part 2 is cut out, and the inside of the roof is penetrated from the place where the jointing is made to prevent water leakage. The ribs and end bent portions 11 are formed integrally in the left and right end face directions. Further, a cross-sectional view of the metal roofing board 1 at a position occupying most of the roofing board at the center of the metal roofing board 1 is as shown in FIG. The upper overlap portion 8, the lower overlap portion 7, and the end bent portion 11 (see FIGS. 1, 4, and 5) are formed and manufactured. A sealant or foam seal can be applied to the lower overlap portion 7 for waterproofing at a vertical joint in the direction of water flow when the metal roofing boards 1 are connected side by side. Needless to say, it can function to improve the property, and the positional relationship between the lower overlapping portion 7 and the upper overlapping portion 8 can be reversed. FIG. 7 shows an example in which the locking portion 3 of the metal roof plate 1 is formed in a step shape. FIG. 8 shows an example in which the groove width of the locking portion 3 is similarly wide. FIG. 9 shows an embodiment in which the locking portion 3 of the metal roof plate 1 is similarly projected in the reverse direction instead of the groove.
In addition, as shown in FIG. 1, these latching | locking parts 3 may be formed continuously to the vicinity of the lower pile part 7 and the end bending part 11, and are formed intermittently in a predetermined position. Needless to say, you can.
As shown in FIG. 10, the first embodiment of the roof hanging element is a hooking part 13 that is hooked on the water return part 2 of the metal roofing material 1 and fixed to the roof base 12, and the clamping force of the clamp-type bracket. Fixed to the back-up part 14 that supports the rear side of the metal roofing board, the tension part 15 that resists the deformation force applied to the falling part 4 of the metal roofing board by the clamping force, and the bent part 16 that hangs and hangs the water return part 2 This is a long or short roof suspension 12 having a portion 17 integrally. A sheet-like metal plate is continuously formed by roll forming and cut into a predetermined length, but it can also be manufactured by bending a metal plate cut into a predetermined dimension with a press or the like. . In addition, as in the case of the roof hanging element 12 shown in the cross-sectional view of FIG. 14, the protruding locking part 13 or the water return part 2 having a shape in which the locking part 13 is matched with the protruding locking part 3 of the metal roof plate 1. And the stretch part 15 which expanded the width | variety according to the falling part 4, and the folding part 16 of folding shape are integrally formed. The same shape and function are obtained by molding with the roof hanging element 12 or the synthetic resin or the like in which the reinforcing rib 19 and the screw nail hole 20 are formed by press forming and bending as shown in FIG. Needless to say, it is possible to manufacture the roof hanging element 12 that has been made. Moreover, it is needless to say that the roof hanging element 12 shown in FIG. 12 of the perspective view may be made within a range of the present invention, for example, by shortening the length to about 20 to 100 mm. Of course, it goes without saying that a length of 100 mm or more may be used.
Further, in order to increase the buckling strength of the strut 15, it is also effective to increase the section modulus of the portion by undulating bending or increasing the number of plates in the direction in which the compressive force is applied, and is within the scope of the present invention. Needless to say.

In addition, the shape of the portion where the metal roofing plates 1 are overlapped in the longitudinal direction is not limited to the shape shown in FIGS. 1 to 5, and is merely a flat plate-like overlapping portion or another waterproof shape of the overlapping portion. Needless to say, the features of the metal roof plate 1 can be combined and made, and are within the scope of the claims of the present invention.
In addition, the intermittent groove-shaped or stepped locking portion 3 formed on the surface of the metal roof plate 1 is formed by pressing the metal plate intermittently in the vicinity of a predetermined portion of a metal fitting to be mounted on the surface in advance. It goes without saying that it can be formed by being partially deformed by a deformable roll type. Moreover, although the shape of the latching | locking part 3 of the metal roof board 1 of the cross-sectional shape shown in FIGS. 1-6 and FIG. 8 is a groove-shaped concave latching part, the metal roof board 1 of the cross-sectional shape shown in FIG. The shape of the locking portion 3 is a stepped shape. However, the shape of the locking portion 3 of the metal roof plate 1 having a cross-sectional shape shown in FIG. 9 is an example in which it is formed so as to protrude to the surface side. However, the cross-sectional shape is an object that protrudes regardless of the illustrated shape. Needless to say, it may be a different shape or a point-like bulge.
Further, the roof hanging element 12 formed with the locking portion 3 in accordance with the shape of the back side of the locking portion 3 formed on the surface of the metal roof plate 1 is inserted into the falling portion 4 on the back side of the metal roof plate 1. When the metal roof plate 1 is lifted up and the metal roof plate 1 is fixed to the roof base by lifting the water return portion 2 of the metal roof plate 1 constructed on the lower side of the metal roof plate 1 and the back-up portion 14 Needless to say, the present invention is applicable even when the shape and position change.
Although the example of a standard shape of this metal roof board 1 is illustrated as an example in FIGS. 1-5, an example like sectional drawing shown in FIGS. 6-9 is also illustrated.

As a concrete second embodiment of the roof hanging element of the present invention, the thing of FIG. 11 of the sectional view of the roof hanging element 12 has a locking portion 13 in which the shape of the locking portion 13 is a stepped shape, and the other portions are slightly different. In addition to being different in shape, the central backup portion 18 is integrally formed by extending the metal plate of the fixing portion 17 and supporting the load applied to the central portion of the metal roof plate 1 between the roof base.
In the third embodiment of the roof hanging element, the metal roof plate 1 is supported under the clamp-type metal fitting 22 to which the snow stopper metal fitting is attached as shown in FIG. Construction is performed on the roof base 25 using the roof hanger 12.
Needless to say, not only the single-piece type cradle 26 but also a long one corresponding to a predetermined length is possible. Needless to say, a resin molded product can be used as a roof member by making parts having the same type of function.
The roof hanging element 12 shown in the sectional view of FIG. 13 as a fourth embodiment of the roof hanging element is a load applied via the clamp-type bracket 22 by extending the metal plate of the central backup portion 18 of the roof hanging element 12 of FIG. Is formed integrally with a cradle 21 that supports the lower side of the metal roof plate 1 and transmits it to the roof base 25 to prevent deformation of the metal roof plate 1, and has a long predetermined length or a clamp. A short roof suspension 12 corresponding to the width of the metal fitting 22 may be used.

Further, the locking portions 3 of the metal roof plate 1 according to the present invention are formed in one row on the surface of the metal roof plate 1 as shown in FIG. However, when the clamp-type metal fitting 22 can be attached, the locking portions 3 can be partially formed at equal intervals in accordance with the planned installation position of the clamp-type metal fitting 22 at a predetermined dimensional pitch. It goes without saying that it is within the scope of the present invention.
In the metal roofing material 1 of the present invention, when the clamp-type metal fitting 22 is inserted in the vicinity of the falling part 4, a hook portion 23 formed at the tip of the clamp-type metal fitting 22 is a predetermined part of the metal roof plate 1. One of the features is that a portion that is hooked on the locking portion 3 and is firmly inserted and fixed is formed at the position.
Further, a back-up portion 14 that supports the roof plate against the clamping force of the clamp-type bracket 22 applied to the roof plate in the vicinity of the locking portion 3 and the falling portion 4 on the back side of the metal roof plate 1, It is one of the features that the metal roof plate 1 is firmly clamped by the portion 15 and the bent portion 16.
Furthermore, on the metal roof plate 1, during construction, the installer steps on it, receives snow weight in the snowfall area, and receives loads such as photovoltaic power generation element plates to be mounted on the roof later. In order to prevent the deformation of the metal roof plate 1 with respect to the load, it is also one of the features that a support mechanism such as a cradle 21 is provided below the central backup portion 18 and the clamp-type bracket 22 in the central portion.
Moreover, in the roof hanging element 12 shown in FIGS. 10 to 11 and FIGS. 14 to 15, the shape and size of the projecting portion 15 are set inside the falling portion 4 of the metal roof plate 1 and the roof plate of the hook portion 5. By forming it to a size that can be mounted, it can be expected that the bending deformation of the falling portion 4 will be reduced even if the clamping force of the clamp-type metal fitting 22 is increased, and the clamp-type metal fitting 22 can have a strong clamping force. . In addition, it is possible to maintain the original waterproof performance of the roof as well as to improve the appearance by reducing the deformation of the portion.
In addition, the shape of the roof hanger is shaped if the bent portion 16 that lifts the back-up portion 14 and the water return portion 2 is effective for reinforcement by increasing the clamping force by the locking portion 13 in which the clamp-type metal fitting 22 is firmly engaged. Needless to say, the roof hanger 12 can be employed regardless of the case. Moreover, about the shape of the roof hanging element 12, an example was shown as a cross-sectional shape in FIGS.
FIGS. 16 and 17 show an embodiment of the tension reinforcement 38 constituted only by the reinforcing mechanism part of the locking part 13, the backup part 14, the tension part 15, and the bending part 16 that resists the clamping force of the clamp-type metal fitting 22. An example is shown.
As for the pedestal of the roof member, an example of a long object integral with the roof suspension 12 as shown in the cross-sectional shape of FIG. 10 or an example of a roof member partially attached to a necessary portion as shown in the perspective view of FIG. Although shown, it is needless to say that the cross-sectional shape may be formed as a pedestal in a plurality of ridges in addition to a ridge, and only the pedestal may be formed long.
This has the effect of preventing the danger of the clamp-type bracket falling off due to a load caused by snow.
On the other hand, it is needless to say that in an area where there is little snow accumulation, the shape and dimension may be such that only the upper surface of the roof plate is prevented from being deformed, such as the projecting portion 15 of the roof hanging element 12 shown in FIGS. 10, 12, and 13. Yes.
Needless to say, the projecting portion 15 and the bent portion 16 are used to hook the water return portion 2 of the metal roof plate 1 and fix it to the roof base 25.

The construction method of the roof member such as the metal roof plate and the roof hanger and the clamp-type metal fittings of the conventional example on the building roof will be described.
The roof hanger as shown in FIG. 21 is the roof hanger 12 of the roof member of the present invention, and can be used for the conventional metal roof plate 33 as well. As shown in FIG. 21, when a roof member is rolled and strongly attached with a clamp-type metal fitting 22, a slight dent deformation to the roof surface occurs. However, it may be adopted as a means of a side-stepped metal roof system. Indicates that it is possible.
In a typical example of a conventional metal roof shown in the sectional view of FIG. 22, a roof base 25 is preliminarily constructed on the roof of the building before the metal roof plate 33 is constructed, and a waterproof paper is formed thereon. Take measures against waterproofing. Next, an eaves starter is attached to the eaves part of the roof base 25, the hook part 36 of the metal roof plate 33 is hooked on the starter and the metal roof board 33 is started to be sprinkled. The suspension fixing portion 37 is fixed to the roof base 25 using a screw nail 30 or the like.
In addition, 31 shows the screw mechanism of the clamp type metal fitting 22, and 35 shows the falling part of the metal roof board 33, respectively.
Next, the second-stage metal roof plate 33 is fixed to the roof base 25 at the fixing portion 37 of the roof hanging element 32 with a screw nail 30 or the like in accordance with the first-stage water return section 34 and the roof hanging element 32. The entire roof is repeatedly built, and the metal roof is rolled up with the roof edges, ridges, and wall connections.
Thereafter, the clamp-type metal fitting 22 is inserted into a predetermined position as shown in FIG. At that time, the clamp-type metal fitting 22 is attached by the hook 23 deforming a part of the metal roof plate 33 and clamping it. The situation where the clamp-type metal fitting 22 is mounted on the roof shows that the metal roof plate 33 is partially deformed and recessed.

Next, a method for constructing the roof member such as the metal roof plate 1 and the roof hanger 12 of the present invention and the clamp type metal fitting 22 on the building roof will be described.
In an example of the state in which the metal roof board 1 of the present invention shown in the cross-sectional view of FIG. 19 is constructed, the roof base 25 of the building is waterproofed with a waterproof sheet or the like in advance before the construction of the metal roof board 1. The roof base 25 is arranged, and an eaves starter is attached to the eaves portion of the roof base 25, and the metal roof plate 1 is started to be hooked by hooking the hook portion 5 of the metal roof plate 1 on the starter. Then, it is fixed to the roof base 25 using a screw nail 30 or the like. After that, the roof hanging element 12 fixes the water return portion 2 of the metal roof plate 1 to the roof base 25 using the screw nails 30 or the like at the fixing portion 17 at a predetermined position or the like where the clamp type metal fitting 22 is installed. In this case, the clamp-type bracket 22 can generally be attached from the second stage of the metal roof plate 1, but the roof suspension 12 is also fixed in advance at a predetermined interval under the first stage metal roof plate 1. The part 17 can be fixed to the roof base 25 with a screw nail 30 or the like.
Similarly, it is repeatedly constructed by the above-described method, and the metal roof is rolled up with the roof edge, the ridge surroundings, the wall joints, and the like.
The method of constructing the roof hanger 12 under the first-stage metal roof plate 1 is as follows. The roof hanger 12 is attached to the position where the falling part 4 of the metal roof plate 1 is correctly attached to the starter, and then the first step. The metal roof plate 1 is rolled and fixed to the roof base 25 with a screw nail 30 or the like at the fixing portion 6.
The hook portion 23 of the clamp-type metal fitting 22 is hooked on the latching portion 3 of the rolled metal roof plate 1, and the clamp-type metal fitting 22 is inserted in the gap between the hook portion 5 of the metal roof plate 1 and the underwater metal roof plate 1. The clamp-type metal fitting 22 is attached by tightening the screw mechanism 31 of the clamp-type metal fitting 22, and after the entire clamp-type metal fitting 22 is constructed, a photovoltaic element plate or the like is attached thereto. These devices are fixed to the roof base 25 indirectly without cutting the roof plate. Since the locking portion 3 formed on the metal roof plate 1 to which the hook portion 23 of the clamp-type metal fitting 22 is hooked is firmly supported by the backup of the roof hanger 12, no depression is generated in the metal roof plate 1 in the vicinity of the locking portion 3. In the metal roof plate 1 of the present invention, the clamp-type bracket 22 can be firmly fixed to the roof base 25.
FIG. 19 is a partial cross-sectional view of an example of a roof construction portion constructed using the metal roof plate 1 and the roof member of the present invention. The metal roof plate 1 is then extended over the lower overlap portion 7. The state where the upper overlapping part 8 of the metal roof plate 1 is overlapped is shown.
The construction method of the present invention as a fixing means for a photovoltaic power generation element, a solar water heater, a snow stopper, etc. is firmly fixed by sandwiching the metal roof plate 1 on the roof base 25 without cutting the roof plate from the viewpoint of waterproofing. Needless to say, it is effective.
