SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a vertical joint structure formed between a plurality of wall panels attached to a frame and between side end faces of the wall panels. A sealing member made of an elastic material is inserted from the inner side of the vertical joint to the skeleton, and a gasket for rain return is inserted into the outer side of the vertical joint than the sealing member. The side is filled with a primary sealing material. The sealing member has an elongated hollow cylindrical main body, and a substantially arcuate shape in a plan view, and both ends of the main body facing the main body side in a longitudinal direction. And a fin portion provided over the entire surface. And this sealing member, while the opposite side of the fin portion from the main body portion abuts the skeleton, and both ends of the fin portion abut on the skeleton side surfaces of both side wall panels forming the vertical joint, while the main body portion is the vertical joint. The rain return gasket is disposed in close contact with the inner side, and the gasket for rain return contacts the side end surface facing the vertical joint of the wall panel, and is inserted into the vertical joint while being in contact with the main body of the sealing member. Configuration.

[0005]

In the present invention, since the sealing member is disposed from the inside of the vertical joint to the skeleton with the fin portion opposite to the main body abutting on the skeleton, the sealing member is attached to the vertical joint. When inserting, the sealing member is inserted into the vertical joint from the fin portion side. The fins are generally arcuate in plan view, and are provided on the outer surface of the main body with both ends thereof facing the main body, respectively. The other side is hard to bend. Therefore, after forming the vertical joint, the sealing member can be easily inserted into the vertical joint from the outside. Also, after both ends of the fins abut on the skeleton side surfaces of the wall panels on both sides that form the vertical joint, depending on the contact of the fins and the characteristics of the fins that are difficult to bend on the side opposite to the main body Since the sealing member cannot be easily pulled out, it is possible to check whether both ends of the fins have contacted the wall-side surface of the wall panel depending on the difficulty of pulling out the sealing member. Becomes

Further, since the gasket for returning rain is inserted into the outer side of the vertical joint with respect to the sealing member in a state of being in contact with the main body of the sealing member, the fin portion is always formed by the gasket for returning rain. The state in which the main body portion abuts on the skeleton at a predetermined pressing force and the main body portion is always in close contact with the side end surface of the wall panel is maintained. Since the inside of the vertical joint is triple-sealed by the rain return gasket and the main body and the fin portion of the sealing member, even if water enters the vertical joint from the primary sealing material, the rain return gasket is used. Further, further intrusion is prevented by the sealing member, and water is reliably prevented from entering the building.
