No girder arch Fire: Galaxy roof as a continuous shell, belongs to the high-order super-static structure, in case of a fire can occur after redistribution of internal forces, slow destruction of the structure of the plant without beam arch, therefore, the Galaxy roof structure itself than normal steel fire performance. Moreover, because the Galaxy interior headroom large roof structure, the ground is not easy to reach the roof of fire, according to architectural design code for fire protection, the roof can also do fire treatment. No girder arch Waterproof: Galactic roof structure catcher connection, and the connection is not part of the water in the cross-section height, water seepage, and thus waterproof structure itself is impeccable. Junction with the lower edge of the roof beams are structural weaknesses in the entire non-girder arch waterproof material, if handled properly, Sichuan waterproof without beam arch will cause water seepage along the wall to the interior, while the connecting parts of the small water corrosion of steel and embedded member, durability affect the structure, we must pay attention to this part of the water treatment design. Usually two flexible waterproof cloth three oil. Country without beam arch, arch without beam, Guangxi Yinhe provided by Guangxi Yinhe Metal Structure Engineering Limited.
