[0029] The back surface of sealing plate 2 is also provided with positioning block 21, and the shape of positioning block 21 is the same as the shape matching, so that positioning block 21 can be embedded into the corresponding cavity 11 of the end 13 of roof longitudinal beam 1, and the position of the end 13 of roof longitudinal beam 1 and the plugging piece is pre-positioned before welding by using the friction force between positioning block 21 and the inner side wall of cavity 11, and the outer edges of the two can also be aligned. Preferably, positioning block 21 has two, which are embedded into two spaced cavities 11 of roof longitudinal beam 1 respectively, so that the position of the pre-positioned plugging piece is more stable.

[0030] The outer edge 24 of sealing plate 2 is matched with the shape of the outer edge 14 of the end of roof longitudinal beam, and after the plugging piece is welded with the end 13 of roof longitudinal beam 1, the adjacent positions between the two are aligned, without obvious joint line or uneven place, so that the appearance of the welded roof longitudinal beam 1 is more beautiful.

[0031] The back surface of sealing plate 2 is also provided with a ring-shaped groove 22, and the ring-shaped groove 22 is connected with each cavity 11 in roof longitudinal beam 1. Generally, a drain hole 15 is arranged at the bottom or near the bottom of roof longitudinal beam 1, one drain hole 15 corresponds to one cavity 11 in roof longitudinal beam 1, and the water or liquid in other cavities 11 flows into the cavity 11 provided with drain hole 15 through the ring-shaped groove 22 on the back surface of sealing plate 2, and is finally discharged through drain hole 15, that is, the ring-shaped groove 22 is used to help drainage of the cavities in roof longitudinal beam 1, and the plugging piece does not cause difficulty in drainage of other cavities 11 in roof longitudinal beam 1 due to plugging the end 13 of roof longitudinal beam 1.
