DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a foundation structure for a roof.

[0002]

2. Description of the Related Art A conventional underlayer structure has a waterproof property,
A base sheet is formed by laying a waterproof sheet. Therefore, the economical burden on the waterproof sheet is inevitable, and the waterproof sheet itself cannot be expected to work in terms of strength, and since the waterproof sheet and the base are non-breathable,
Condensation may occur. On the other hand, the offcuts generated during the molding of the metal shingle are treated as industrial waste, and the waste problem and economic loss must be improved.

[0003]

The problem to be solved is to improve the waste problem and economical loss by effectively utilizing the scraps generated during the molding of the metal shingle, and to improve the base and the base surface. It is an object of the present invention to provide a base structure for a roof that solves the problem of dew condensation between the roofs, has excellent heat insulating properties, heat retaining properties, and moisture proof properties, and has an improved base surface strength.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a base surface is formed of a plurality of metal waterproof plate members laid on the base at least in a longitudinal direction, and each of the waterproofing members is formed of a metal waterproof plate member. The plate member is characterized in that it has a cross-sectional shape having at least a convex portion, and has a vent between adjacent ends that are overlapped and communicates with a space in the convex portion. Further, the present invention is characterized in that each of the waterproof plate members has the same cross-sectional shape having convex portions and concave portions alternately arranged in parallel. Further, in the present invention, the base is inclined in the direction of the eaves ridge, and the overlapped end of the waterproof plate member is provided with the upper end on the lower end. It is characterized by.

[0005] The base in the present invention is a base for a gable roof, a flat roof, an arch roof, and other various roofs, and is formed of a purlin such as a base plate or a steel frame. The metal roofing sheet is a metal sheet member having various lengths and widths generated when a fixed-length roofing sheet is molded or a metal sheet member having a constant length and width. Further, the vent is a gap formed in the overlapped portion when the end portion of the aspect of the aspect in which the cross-sectional shape of the metal waterproof plate member is the same form, and the convex portion in the waterproof plate member in advance, There is an embodiment in which the projections are formed in a ratio relationship such that a gap is formed between the projections in the overlapping portion. There is also a mode in which the waterproof plate member has a double up-down structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 4 exemplify an embodiment of a roof base structure of the present invention. A base 1 which is inclined in the eaves ridge direction has an eaves ridge direction and a girder row direction. A plurality of metal waterproof plate members 2, adjacent upper end portions 2a and lower end portions 2b, and left end portions 2c and right end portions 2d are laid and fixed by superimposing them, respectively, to form a ground surface a. . Each metal waterproof plate member 2 has various lengths and widths, and a waterproof plate member 2 having a cross section in which convex portions 2e and concave portions 2f along the eaves ridge direction are alternately arranged in parallel, a convex portion along the eaves ridge direction. The waterproof plate member 2 having a cross-sectional shape in which 2e and the concave portion 2f are arranged side by side, the waterproof plate member 2 having a cross-sectional shape having a convex portion 2e along the eaves ridge direction, and the convex portion 2e and the concave portion 2f in each waterproof plate member 2 Molded in the same cross-sectional form. Each of the waterproof plate members 2 having different lengths and widths is appropriately combined, and the lower end portion of the upper stage is placed on the upper end portion 2a of the lower stage adjacent thereto.
2b is polymerized to form a ventilation port 2h communicating with the space 2g in the convex portion 2e between the upper and lower convex portions 2e in the superposed portion.
The ventilation port 2h is formed in the overlapping portion of each metal waterproof plate member 2, and ventilation is performed between the ventilation port 2h and the space 2g through the ventilation port 2h. Then, a metal roof plate 4 is roofed on the ground surface A by a known appropriate attaching means.

FIG. 5 illustrates another embodiment of the underlayer structure of the roof according to the present invention. Since the configuration is basically the same as that of FIGS. Are omitted, and different configurations will be described. The metal waterproof plate member 2 is of a type having a cross-sectional shape in which the height and width of at least the convex portion 2e are large, and a type having a cross-sectional shape in which the height and width of at least the convex portion 2e are slightly smaller, The metal waterproof plate member 2 is laid and fixed by combining the two.
A ventilation port 2h is formed so as to communicate with the space 2g at the overlapped portion of.

FIG. 6 exemplifies another embodiment of the foundation structure of the roof according to the present invention. Since the structure is basically the same as that of FIGS. Are omitted, and different configurations will be described. The metal waterproof plate member 2 is formed in a vertical double structure with the lower metal waterproof plate member 3, and the lower waterproof plate member 3 has a low convex portion.
3a and shallow concave portions 3b are formed alternately in parallel.

FIG. 7 illustrates another embodiment of the underlayer structure of the roof according to the present invention. Since the configuration is basically the same as that of FIG. 6, the description of the common configuration will be omitted. do it,
The different configuration will be described. The lower metal waterproof plate member 3 on the lower side of the upper metal waterproof plate member 2 is formed by superposing a plurality of plate members having different lengths and widths on adjacent portions thereof.

【The invention's effect】

A. According to claim 1, since the base surface is formed of a plurality of metal waterproof plate members laid at least in the length direction laid on the base, the length and width generated when molding the roof plate are various. The material can be effectively used as a waterproof plate member, which can reduce waste problems and economic loss. And, the transportation and construction work of the metal waterproof plate member is easier than a single long one. B. According to the above paragraph, since each metal waterproof plate member is formed in a cross-sectional shape having at least a convex portion, the ground surface strength is improved, and the weight of the snow and the wind pressure are strong. C. According to the above paragraph, each metal waterproof plate member has a cross-sectional shape having at least a convex portion, and has a ventilation port communicating with a space in the convex portion between adjacent overlapping ends. For this reason, ventilation is performed between the base side and the waterproof plate member via the air holes and the space in the convex portion, and there is no fear of dew condensation, and the moisture resistance is excellent. In addition, the space in the convex portion is insulated, so that the rise in the indoor temperature due to the solar heat in the summer is reduced, and the heat radiation in the winter is suppressed, so that the heat retention is excellent. D. According to the second aspect, since each of the metal waterproof plate members has the same cross-sectional shape having the convex portions and the concave portions alternately arranged in parallel, the construction work can be rapidly performed only by the size combining work.
The recess works as a gutter, and can smoothly drain water from the roof. E. FIG. According to claim 3, the base is inclined toward the eaves ridge,
Since the overlapped end of the waterproof plate member is provided with the upper end on the lower end, convection between the underside and the waterproof plate member via the respective ventilation holes and the convex portions is prevented. Happened
Ventilation is performed smoothly to prevent condensation.
