AI Technical Summary

Technical Problem

Existing metal-faced sandwich composite panels fail to effectively demonstrate electromagnetic shielding performance and have low construction efficiency in shielded room construction, and also fail to meet green environmental protection and energy-saving requirements.

Method used

The design adopts two new integrated panels: one consisting of an enclosure layer, a sandwich layer, and a shielding layer, and the other consisting of a shielding layer, a sandwich layer, and an enclosure layer. The enclosure layer is made of color-coated steel sheet, the sandwich layer is made of materials such as rock wool, and the shielding layer is made of galvanized steel sheet. They are produced through a fully automated molding composite production line and are designed in duckbill and wave shapes to achieve electromagnetic shielding, sound insulation and noise reduction, and energy saving effects.

Benefits of technology

It achieves highly efficient electromagnetic shielding, meeting and exceeding national military standards. It boasts high construction efficiency, superior quality, strong safety, and low cost. It is suitable for various shielding room scenarios, features long lifespan and maintenance-free operation, and combines sound insulation, heat insulation, and moisture retention functions, meeting green and environmentally friendly requirements.

Abstract

This utility model discloses a metal-faced sandwich composite integrated panel for shielded rooms, relating to the fields of electromagnetic shielding and building envelope technology. This utility model includes a new integrated panel one for external building shielding and enclosure and a new integrated panel two for internal building shielding, decoration, and sound absorption. New integrated panel one consists of an enclosure layer, a sandwich layer, and a shielding layer; new integrated panel two consists of a shielding layer, a sandwich layer, and an enclosure layer. Through the unique design of new integrated panels one and two, this utility model is suitable for a wide frequency band of 10kHz-50GHz, exhibiting excellent shielding effectiveness, meeting and exceeding the national military standard GJB5792A-2021C level standard, fully meeting the design requirements of anechoic chambers and other types of shielded rooms. New integrated panels one and two are produced and constructed using innovative models and processes, achieving true integrated shielding, resulting in higher construction efficiency, better quality, stronger safety, shorter cycle time, and higher cost-effectiveness.
