Description

  The present invention relates to a mounting structure for a roofing panel.

  As a roofing material for a house, a natural slate made of a natural basalt stone is generally used. This natural slate is a roofing material that is durable, fire and water resistant, lightweight and has a good appearance.

  The natural slate is generally formed in a desired plane shape with a vertical and horizontal dimension of about 200 mm from the viewpoint of transportation, handling, and the like. Therefore, in the case of using this natural slate to wipe the roof, conventionally, this natural slate has been wiped by nailing on a baseboard or the like while taking a predetermined overlap and wipes one by one.

This conventional wiping method will be described with reference to FIG. 5. A roofing 2 is stretched on a roof base plate 101, and a number of wiping materials 103 at the eaves are placed on the roofing 2 in the lateral direction (direction perpendicular to the flow direction of the roof). Are connected to the base plate 101 with the nail 104. Next, the upper wiping material 105 is placed on the wiping material 103 at the eaves portion with a predetermined overlap L ₁ and wiping foot L ₂ , and a large number of wiping materials 105 are also arranged in the horizontal direction in this upper stage. To connect. In addition, the position of the joint part 106 between adjacent wipes is shifted as shown in FIG. 5 between the upper stage and the lower stage. Then, the wiping operation as described above is repeated to wipe the entire surface of the roof with a large number of wiping materials.

  In the above-mentioned conventional wiping method, the wiping materials adjacent in the lateral direction are not connected to each other, and each wiping material 103 is nailed only at its upper end and the lower end is a free end. When a strong wind blows from the downstream to the upstream of the roof, each wiping material is easily peeled off.

  Moreover, in order to prevent the intrusion of rainwater, it is necessary to stack three layers of wiping materials. When three layers are stacked in this manner, the amount of natural slate used is increased and the cost is increased.

  In order to solve such a problem, the present applicant has previously proposed a panel as shown in FIGS.

  This panel 201 is provided with a connecting plate 203 protruding on the back surface on one side by a double-sided adhesive sheet 202, and water return 204 is formed on both side ends of the connecting plate 203.

  Then, as shown in FIG. 7, first, the panel 201A is fixed to the roof base plate by the nail through the nail hole 205 formed on the upper side, and then another panel 201B is attached to the connecting plate 203 side of the panel 201A. The double-sided adhesive sheet 202 is adhesively connected, and the panel 201B is fixed to the base plate with a nail.

  In this way, necessary panels are fixed in a row in a direction (lateral direction) perpendicular to the flow direction of the roof.

  Next, the upper panel is arranged according to the above-mentioned row, and the lower surface of the lower edge side is arranged so as to overlap the upper surface of the upper edge portion of the lower row of panels, and it is fixed to the base plate with nails as described above.

By wiping each panel in this manner, the panels in the row direction are connected to each other by the double-sided sheet 202, and the upper and lower panels are overlapped, so that the panel is lifted by the wind from below. It is possible to reduce the amount of use of the panel by suppressing the overlap size of the panel.
Japanese Patent No. 2607850

  In the above-mentioned Patent Document 1, the overlapping dimension between the upper and lower panels can be shortened, but the lower edge of each panel is not fixed to the field plate side, so it is unstable, and when the wind is strong, There is a risk that the lower edge side may be lifted.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to propose a roofing panel mounting structure that exhibits the effect of Patent Document 1 and further prevents the panel from lifting on the lower edge side.

Is held on the roof base by the fastening device, and the lifting of the panel is prevented by this fastening device.

  Therefore, by the cooperation of the above-described two loads and holding by the fastening device, it is possible to increase the blowing prevention force against the blowing of wind in each panel.

  According to the present invention, in each panel, the floating prevention force of each panel against wind blowing, that is, the panel holding force can be increased.

  Thus, the ability to increase the holding power of each panel is to reduce the amount of polymerization between the lower panel and the upper panel, to reduce the amount of panel used on the entire roof surface, and to reduce the construction cost. Can do.
