Description

Technical Field

[0001] The utility model relates to the technical field of building walls, in particular to a concrete wall structure for enhancing electromagnetic shielding. Background Technique

[0002] In recent years, due to the development of science and technology, the number of devices generating electromagnetic radiation has increased exponentially, such as nuclear magnetic resonance systems, various switches, base stations, industrial control computers, servers, etc. The electromagnetic radiation generated by them has increased significantly, reaching a level that directly threatens human health, known as electromagnetic pollution. Currently, most electromagnetic shielding and protection rooms are made of expensive metals. For example, beryllium copper alloy is used as the material for electromagnetic shielding rooms, and the cost of beryllium copper alloy bars is very high. Moreover, in some classified fields such as commercial and military environments, a highly confidential environment is required to ensure that classified meetings, etc. are not made public or eavesdropped. Telecom eavesdropping is a common eavesdropping means. Therefore, for such classified environments with high confidentiality requirements, the ability to prevent electromagnetic radiation needs to be strong.

[0003] The prior art publication number CN207538245U discloses a novel electromagnetic shielding wall structure, including an electromagnetic shielding wall main body. The electromagnetic shielding wall main body is provided with an outer wall and an inner wall. A vacuum interlayer is arranged between the outer wall and the inner wall. Support columns are evenly arranged in the vacuum interlayer. Both ends of the support columns are fixed in grooves, and the grooves are connected to one side of the outer wall and one side of the inner wall. The vacuum interlayer is filled with a first sound-absorbing cotton.

[0004] The wall in the above device is an integral body, which is integrally cast and butt-jointed during construction. The electromagnetic shielding effect is easily affected by on-site construction. When the construction quality does not meet the standard, the electromagnetic shielding effect is poor. The quality of electromagnetic shielding rooms built by using the above device and method is inconsistent, and it is difficult to form a unified standard, which is not conducive to large-scale popularization and use.
