[Problems to be solved by the invention]
However, although Patent Literatures 1 and 2 relate to a roof material having a hook structure, the steps of the connecting portions are small, and there is a thin appearance in appearance. For this reason, it is conceivable to increase the step, but when the step is increased, there is a problem that the step becomes weak against the load and is deformed during work on the roof.
[0005]
[Means for Solving the Problems]
In order to solve such a drawback, the present invention provides a metal roofing material in which a male-female connection structure having a hooking structure is formed on a side edge in a width direction. The metal roofing material and the backing material are integrated by fitting the lower insertion edge into the hook groove that opens upward on the water side, and a concave groove is formed on the back surface of the backing material The left and right ends are provided with a roof material having a male-female connection structure.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the roofing material according to the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 (a) to 2 (c) are explanatory views showing a typical example of a roofing material A composed of a metal roofing material B and a backing material C. FIG. 4 (a) to 4 (c) are explanatory views showing a joint portion, FIG. 4 (a) is an end view taken along line bb of FIG. 7, and FIG. 5 is an explanatory view showing a typical example of a roofing material A. is there. In the drawing, α indicates a base and β indicates a fixture such as a nail. FIG. 2C is a sectional view taken along the line aa in FIG. 2B.
[0007]
The foundation α indicates a wooden foundation composed of a rafter 1, a ground board 2, and a waterproof sheet 3 (indicated by a dashed line) as shown in FIG. That is, it is a groundwork α of a general structure in which the baseboard 2 is laid on the rafter 1 and the waterproof sheet 3 is provided on the baseboard 2. In addition, H-shaped steel, I-shaped steel, grooved steel, lightweight grooved steel, lip channel steel, equilateral angle steel, unequal angle angle steel, square steel (square pipe), circular steel (circular pipe), It is also possible to use a steel base material using such as. Of course, when the existing roof is to be renovated as it is, existing roofs (not shown) such as a metal horizontal roof, a metal tile rod roof, a new tile, a tile roof, etc. are formed on the foundation α. The existing roof structure is the foundation α. Of course, the base α without forming the waterproof sheet 3 may be used.
[0008]
The metal roofing material B is, for example, a metal plate (a color steel plate, a copper plate, an aluminum plate, a titanium plate, a stainless steel plate, a sandwich steel plate, a clad steel plate, or the like) formed by roll forming, press forming, extrusion forming, or the like. . Of course, instead of the metal roofing material B, the roofing material A may be formed of a ceramic material, a synthetic resin material (plastic), or the like instead of the metal roofing material B.
[0009]
More specifically, the metal roofing material B is in the shape of a long plate, and as shown in FIG. 2, the decorative surface 4, the back surface 5, and the underwater end of the decorative surface 4 hang downward. The stepped decorative surface 6 and the insertion edge 7 are formed by bending in a substantially U-shape so as to open to the upper side of the water, and the decorative surface 4, the stepped decorative surface 6, and the insertion edge 7 form a substantially U-shaped. The male connection part 9 is formed by forming a hook groove 8. 9a is an insertion groove.
[0010]
As shown in FIG. 2, a fitting on the water-side end of the decorative surface 4 to be fitted with the insertion edge 7 having a substantially U-shaped cross section with the front end of the decorative surface 4 opened downward. A mating groove 10, a fitting edge 11 serving as an upper edge of the fitting groove 10, and a fixing surface 12 are formed to form a female connecting portion 13. Further, a locking piece 14 and a locking groove 15 as shown in FIGS. 4 (a) to 4 (c) are formed at the end of the decorative surface 4 and connected and fixed as shown in FIG. 4 (a). Things. 13a is a hook groove.
[0011]
As shown in FIG. 1, the insertion groove 9a and the hook groove 13a are formed by integrating the metal roofing material B and the backing material C shown in FIGS. Material C is prevented from coming off metal roofing material B, and the use of an adhesive is eliminated. In addition, the hook groove 13a also has a positioning function, and is useful for preventing the backing material from shifting.
[0012]
The backing material C functions as a waterproofing material, a heat insulating material, a reinforcing material, a step forming material, a sound absorbing material, a cushioning material, a fireproofing material, a dew condensation preventing material, etc., and mainly uses a synthetic resin foam molded material. Is what you do. Examples of the material include synthetic resin foams such as styrene foam, polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, and urea foam. And a curing agent and a foaming agent are mixed, discharged onto the back surface of the front surface material or the back surface material, and heated, reacted, foamed, and cured. In the core material, various types of flame-retardant materials such as lightweight aggregates (pearlite particles, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.) and fibrous materials (glass wool, rock wool, carbon fiber, graphite) Etc.) can be mixed to improve fire resistance and fire resistance.
[0013]
As shown in FIG. 2B, the shape of the backing material C includes a horizontal surface 16, a projecting piece 17 protruding below the horizontal surface 16, a notch 18 formed by the projecting piece 17, and a water surface of the horizontal surface 16. It is formed in a long shape from a waterproof piece 19 protruding upward on the side, a hook piece 20 fitted into the hook groove 13a, a convex portion 21 and a concave groove 22 formed by cutting out the back surface.
[0014]
As shown in FIG. 8, the concave groove 22 forms a communicating ventilation path R on the back surface of the roofing material A from the eaves P of the house H to the ridge Q, and allows air entering from the eaves to pass through the ventilation opening of the ridge Q. It is designed to discharge water, suppress summer temperature rise, and release moisture generated indoors to the outside.
[0015]
The locking piece 14 and the locking groove 15 are as shown in FIGS. 4B and 4C, and the locking piece 14 is inserted into the locking groove 15 as shown in FIGS. 6A and 6B. 4 (a) and FIG. 7 by integrating them.
[0016]
What has been described above is only one embodiment of the roofing material according to the present invention, and can be formed as shown in FIGS. 9 (a) to 9 (c) and FIG.
[0017]
FIGS. 9A to 9C show that the notch 23 is formed in the backing material C, and when the locking piece 14 and the locking portion 15 are connected, the end of the backing material C is It is formed in order to prevent it from hitting the mold connecting portion 13 (step h) and becoming difficult to perform.
[0018]
【The invention's effect】
As described above, according to the roofing material according to the present invention, (1) a roofing material having a large step can be formed by forming the backing material, and the roof has a design-heavy image. {Circle around (2)} Even if the step is formed large, it is not deformed by the load. {Circle around (3)} The backing material can be integrated with the metal roof material by the insertion groove and the catch groove, and the use of an adhesive or the like can be eliminated. (4) The hook groove exerts a positioning function and is useful for preventing the backing material from shifting. (4) Due to the formation of the groove, a ventilation path communicating with the back of the roofing material from the eave to the ridge is formed, air entering from the eave is exhausted from the ventilation opening of the ridge, and the temperature rise in the summer is suppressed, In addition, moisture generated from indoors can be released to the outside. (5) The left and right connections are simple. There are features and effects.
