In this goby-wound metal roof, as shown in FIG. 5, while fixing the clip to the foundation steel frame, the clip is sandwiched between the opposite side edges of the adjacent metal roof panels, and the clip is goby-wound.
This construction is applied to all roof panels to construct a floating roof.However, in such a metal roof, in order to prevent leakage of rainwater, etc., it is necessary to secure water stopping at the upper end of the water gradient. is important.

Then, in the conventional goby-wound roof, a water stop door having substantially the same shape as the roof panel cross-sectional shape is fixed to the water gradient upper end of the roof panel, and a cartridge-type sealing material is used to connect the roof panel and the water stop door. The sealing material was extruded along the contact line and fixed to prevent leakage of rainwater or the like.

(Problems to be solved by the invention) However, in the conventional seal structure at the upper end of the water gradient, the sealing material is pressed from the outside to be fixed to the contact portion between the roof panel and the water stop door, so that the goby winding portion is fixed. However, there is a problem that the sealing material is not filled in and the rainwater and the like enter the goby winding portion at the upper end of the water gradient due to the capillary phenomenon, and there is still concern about water leakage.

In view of such concerns, it is an object of the present invention to provide a goby winding roof seal structure at the top of a water gradient of a goby type roof that can reliably prevent intrusion of rainwater or the like into the goby winding portion at the top of a water gradient.

On the other hand, the clip is sandwiched between the sheets and wound with a goby, while the water-stop door is fixed to the water gradient upper end of the roof panel, and a sealing material is fixed to the contact portion between the water-stop door and the upper roof panel. In the type roof, using a sealing part in which a fitting groove for accommodating and fitting the goby winding portion is formed in the longitudinal direction of the lower surface, and an injection hole for a sealing material communicating with the fitting groove is formed at the front end portion, The fitting groove of the sealing component is fitted into the goby winding portion at the upper end of the water gradient, and the sealing material is injected from the injection hole to seal the goby winding portion. " .

Here, the seal component may be made of any material, but in consideration of cost and the like, it is preferable to use a molded product of a polymer synthetic resin material.

Further, in order to further improve the sealing property of the goby winding portion at the upper end of the water gradient, "a seal material outflow portion is formed in the substantially central portion of the seal component, and a part of the seal material is fitted into a fitting groove It is desirable that it be made to flow out from the rear end and at the same time to flow out from the outflow part of the seal component so as to be continuous with the sealing material on the water blocking surface side.

(Operation) In this invention, since the seal part is fitted in the goby winding part at the upper end of the water gradient and the seal material is injected into the gap, the seal material is provided between the fitting groove of the seal part and the roof panel goby winding part. Evenly distributed over the space of the water and thus the goby winding at the top of the water gradient is completely sealed.

In addition, an outflow portion of the seal material is formed in the substantially central portion of the seal component, and the excess seal material is caused to flow out from the rear end of the fitting groove of the seal component and outflow from the outflow portion. The sealing material is continuous with the sealing material on the side of the water-stopping surface that is covered on the sealing component, and the goby winding portion at the upper end of the water gradient is more completely sealed.
