PURPOSE:To reduce the stress due to local contact, by placing two reinforcing parts having a cutout in the overlapping part over the mold match line section of the panel on the side surface of the panel, and by winding a band steel over the reinforcing parts. CONSTITUTION:Two reinforcing metallic parts 2, 3 are arranged over the side surface of the panel, and a band steel 4 is wound on these reinforcing parts 2, 3 to form an explosionproof Braun tube. Long cutouts 2a, 3a having a length of 60-70mm. are formed around the overlapping part of the reinforcing metallic parts in the mold match line 5 section of the panel 1 and it is fastened by the band steel 4. Accordingly, the end part 2b of the cutout 2a of the reinforcing part 2, the end part 3b of the cutout 3a of the reinforcing part 3 and the inner side surface 4a of the band steel 4 come in contact with each other along the mold match line 5 of the panel 1, and thus the local stress exerted on the mold match line 5 is dispersed. As a result, generation of a crack is avoided. |
