Electromagnetic shielding telescopic structure and installation method thereof

Abstract

The invention discloses an electromagnetic shielding telescopic structure and an installation method thereof. The structure includes two vertical columns installed on two sides of an expansion joint on a fixed base. A lower shielding plate, a middle shielding plate and an upper shielding plate which are made of elastic materials and have the function of electromagnetic shielding are orderly installed between the two vertical columns, the lower shielding plate is installed on the expansion joint of the fixed base and is fixedly connected to the middle shielding plate through a front shielding pressing strip and is fixedly connected to the solid base through a back shielding pressing strip, and the middle shielding plate and the upper shielding plate are connected by rivets to form a telescopic shielding unit. According to the electromagnetic shielding telescopic structure, the horizontal cross-section shapes of the lower shielding plate, the middle shielding plate and the upper shielding plate are stretched Pi shapes, the shielding plates can be installed adaptively according to the sizes of different expansion joints during installation, and the versatility is high. According to different requirements, holes can be made in the middle shielding plate and the upper shielding plate to reduce a structural weight and air resistance.

Description

technical field [0001] The invention belongs to the field of electromagnetic shielding, in particular to an electromagnetic shielding telescopic structure and an installation method thereof in the field. Background technique [0002] In modern society, with the development and popularization of electronic technology, the electromagnetic signals generated by electronic equipment are becoming more and more complex and diverse. For occasions with certain requirements on the electromagnetic environment such as bridges, it is necessary to carry out electromagnetic shielding. Due to the expansion joint The common structural forms are mostly metal and rubber composite structures, and the electromagnetic shielding here is difficult to achieve. Due to the unavoidable error of expansion joints caused by construction, there are large errors in the height of adjacent sides of the expansion joints and the front and rear positions, and the width of each expansion joint is quite different....

[0002] In modern society, with the development and popularization of electronic technology, the electromagnetic signals generated by electronic equipment are becoming more and more complex and diverse. For occasions with certain requirements on the electromagnetic environment such as bridges, it is necessary to carry out electromagnetic shielding. Due to the expansion joint The common structural forms are mostly metal and rubber composite structures, and the electromagnetic shielding here is difficult to achieve

Due to the unavoidable error of expansion joints caused by construction, there are large errors in the height of adjacent sides of the expansion joints and the front and rear positions, and the width of each expansion joint is quite different. Therefore, the metal structure that can be adjusted in one direction can theoretically meet the shielding requirements , but for expansion joints with large errors, it is difficult to install
