  The illustrated embodiment will be described in detail below.

  Reference numeral 1 denotes a roof plate made of a color steel plate or a base steel plate according to an embodiment of the present invention, which is, for example, a vertical rectangle having a width of 914 mm, a length of 20 m, and a thickness of 0.5 mm. 2 is a thin superbutyl double-sided adhesive tape having a width of about 100 mm, which is stuck on the long side edge 1 'of one side of the vertical rectangular roofing sheet material 1 over its entire length. It is stuck.

  For example, 4 is a single-sided adhesive tape having a width of 120 mm, a length of 20 m, and a strip having a required thickness.

  Construction of the waterproof roof structure of the present invention using the roof plate material 1 and the single-sided adhesive tape 4 is performed as follows.

The asphalt roofing 6 on the roof base 5 is first laid with the roof sheet material 1 of the previous order (FIG. 3 (a)).
Next, the release paper 3 of the superbutyl double-sided adhesive tape 2 of the roof board material 1 is peeled and removed, and the other side long edge 1 "where the superbutyl double-sided adhesive tape 2 of the next-order roofboard material 1 is not attached is used. Is laminated on the double-sided pressure-sensitive adhesive tape 2 from which the double-sided pressure-sensitive adhesive tape 2 has been peeled off, and the overlapped portion is pressed and adhered with a required roller. ”Is superposed and adhered to the long side edge 1 ′ of one side of the roof sheet material 1 in the preceding order through the double-sided adhesive tape 2.
At the same time, the portion other than the other long side edge portion 1 ″ of the roof sheet material 1 of the next order is adapted to the asphalt roofing 6 and the modal truss screw 7 is arranged at a pitch of, for example, 600 mm along the center line of the overlapped portion. Further, for example, a tornado screw 8 is driven between the screws 7 at a pitch of 100 mm, and the overlapped portion is firmly fixed to the roof base 5 (FIGS. 3B to 3D) or the overlap. The parts are stitched together.

  Thereafter, the single-sided adhesive tape 4 is placed on the other side long side edge 1 "in the superposition state of the next-order roofing sheet material 1 and the previous-order roofing sheet material 1 with the adhesive surface down. In the state where the head ends of the screws 7 and 8 and the end face of the other long side edge portion 1 ″ and the end face of the double-sided adhesive tape 2 are covered, the adhesive is pressure-adhered with a required roller. , Make it familiar with the roof plate 1 (FIGS. 3E to 3F).

  This completes the construction of the desired waterproof roof structure.
