Construction method of indoor anti-static shielding mesh system

Abstract

The invention relates to a construction method of an indoor anti-static shielding mesh system. The shielding mesh system comprises roof surface shielding grids, ground shielding grids, wall surface shielding grids, window anti-static shielding grids and metal doors which are respectively formed by welding galvanized round steel of phi 8-12 millimeters, wherein all the grids are square. The construction method particularly comprises installation steps of all the grids. According to the method, a signal power supply room, a computer room, a machine room and the like which be required to be subjected to protecting and shielding on electromagnetic pulses adopt a room-in-room construction according to the Faraday electromagnetic shielding principle. The complete indoor anti-static shielding mesh system can be formed by installing and connecting the roof surface shielding grids, the ground shielding grids, the wall surface shielding grids, the window anti-static shielding grids and the metal doors. The whole system is simple in construction process, strong in operability and short in working cycle.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method of an indoor antistatic shielding net system. It is especially suitable for the construction of indoor anti-static shielding systems in railway station signal rooms, power supply rooms, mechanical rooms, computer rooms and other indoor anti-static shielding systems that require comprehensive protection against lightning and electromagnetic compatibility for railway signal equipment. Background technique [0002] With the development of urban construction, urban transportation has rapidly developed into a network railway pattern, which greatly improves people's quality of life. Due to the important role of railway traffic signal equipment informatization in the operation process, the protection and shielding requirements for lightning and electromagnetic pulse are getting higher and higher. Once lightning causes the shielding system to fail an...

AI Technical Summary

Problems solved by technology

[0003] At present, the anti-static shielding design and construction methods in various information control rooms such as airports and railways are backward. The traditional anti-static shielding system uses steel mesh and iron plates. This construction technology has a long construction period, high project cost, and complicated construction operations. cumbersome

In particular, the on-site production of professional and finished anti-static shielding metal grids has large dimensional deviations, flatness does not meet the requirements, and the control of on-site welding quality is difficult. The professional requirements for weld quality inspection are high and cumbersome. Noise, dust, poisonous gas and liquid will cause environmental pollution

[0004] In addition, the existing steel mesh and iron plate technology is not designed specifically for the anti-static requirements of the signal room. If it is applied to the signal room, it will cause problems such as high cost, long construction period, complicated operation, and efficiency.

The quality of the metal anti-static shielding net directly affects the entire shielding system, and a little mistake in the construction process of the product may bury hidden dangers for major safety accidents in the future
