Problems solved by technology
However, the structural anti-corrosion paint is formed once in the factory, and the structural columns are separated by anti-corrosion paint. Such on-site secondary installation is difficult to construct as the floor increases, and there are potential safety hazards, which affect the installation period; The amount of materials used for lightning protection down conductors increases, and the installation cost increases. In addition, the installation of lightning protection down conductor brackets mostly adopts direct welding, which destroys the anti-corrosion paint on the surface of structural columns, and adds flat steel on site, which affects the overall appearance of the building. Off-line welding and fixing are not conducive to the realization of detachable performance of modular buildings

The invention relates to a detachable lightning protection grounding down lead connecting method for a steel module building. A stainless steel connecting plate which is punched and threaded is prefabricated on a steel structure stand column in a factory, wherein a galvanized flat steel connecting piece is connected with the stainless steel connecting plate through a bolt; and the connection and mounting of a lightning protection down lead are rapidly realized through the connection and application of the steel stand column and a short flat steel strip. The method has the beneficial effects that the modules can be spliced one by one according to the sequence of the field splicing modules, the total mounting period of the field module building is shortened, the safety of constructors is improved, the mounting cost is saved, and the appearance of the building is more attractive; the method is simple to operate, rapid and efficient, the measure cost is reduced while high quality guaranteeis obtained, the efficiency is improved, and the method can be widely popularized and applied in the manufacturing process of the steel structure module.
Description
technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a detachable lightning protection grounding downconductor connection method for steel module buildings. Background technique [0002] The prefabricated steel structure modular building is to divide the single building into several space modules. The fine decoration and even the cleaning are all completed in the factory, and then transported to the site to build the house like building blocks. However, due to the high degree of prefabrication and integration of steel module buildings in the factory, especially the anti-corrosion paint of the main structure is formed in the factory at one time, the structural columns are separated by anti-corrosion paint, which cannot be directly used as lightning protection down conductors. Lines generally adopt the method of on-site secondary installation. Weld the galvanized Ω-shaped connection card and the galvanize...
