Definitions
- the present invention relates to a magnetic shield and a method of manufacture of such shield.
- the present invention sets out to provide an improved magnetic shield.
- a pre-fabricated magnetic shield comprising a laminate panel having at least two co-planar sheets having electromagnetic shielding properties, the sheets being arranged and connected in such a way as to be offset from each other so to provide an overlap along each sheet edge.
- the panel comprises between two and five sheets. Preferably still, the panel comprises 3 sheets.
- the sheets are made of a material that has high permeability properties.
- the sheets are made from high permeability silicon steel.
- the magnetic shield comprises a plurality of panels connected together in such a way that the edges of each sheet of one panel abut the corresponding edges of each sheet of an adjacent panel.
- the overlaps are butt joined.
- a method of manufacturing a magnetic shielding panel comprising the steps of arranging at least two sheets having electromagnetic shielding properties in a co-planar relationship such that the sheets are offset from each other so to provide an overlap along each sheet edge, and connecting the sheets together.
- Figure 1 is a plan view of a magnetic shield constructed in accordance with the present invention.
- Figure 2 is a plan view of a plurality of shields connected together.
- a magnetic shield comprises a panel 5 which itself comprises three sheets 1OA, 1OB, 1OC of material having electromagnetic shielding properties.
- the sheets lOA-C are preferably made from a high permeability, silicon steel.
- the sheets lOA-lOC are approximately 1 mm thick but can be made to any desired thickness depending on their intended application. Sheets made from such a material are lightweight and consequently, the panel 5 constructed from the sheets is lightweight which is highly advantageous.
- a panel 5 may be formed of any number of sheets to provide a desired overall thickness for the intended application.
- the applicant has found, to date, that the optimum range of sheets is between 2 and 5.
- the steel may be grain oriented or non-grain oriented. It is clear that the sheets should not be limited to a specific material. Other metallic materials could, for example, be used such iron, cobalt or nickel. Depending on the characteristics of the electromagnetic field to be shielded, the sheets lOA-C could also include or consist of other materials such as aluminium, lead, copper or ceramic or polymeric material.
- the top sheet 1OA may be dry-lined to provide an aesthetic appearance.
- the sheet 1OA may be coated with, or may otherwise include, an anti-corrosive or anti-bacterial compound.
- the sheets lOA-lOC are connected together to form the panel 5 by spot-welding or similar technique.
- An example of the position of the spot welds 14 can be seen in Figure 1.
- the sheets lOA-lOC could alternatively be connected together using mechanical fixtures and/or adhesive.
- the sheets lOA-C may be connected directly together or may be arranged in the form of a sandwich with a material layer located therebetween to improve the shielding effect or provide further properties that may be advantageous to the shielding structure.
- the offset arrangement of the panel 5 is such that, when number of panels 5 are located against one another with the top sheets 1OA of each panel 5 adjacent (see Figure 2), the overlaps 12 around the panel edges ensure a uniform thickness of shielding material is provided across the entire shield surface, including at the connections between each panel 5.
- each panel 5 The overlaps 12 of the sheets lOA-lOC of each panel 5 are butt- joined to minimise leakage.
- the edges of each sheet are designed in such a way that the sheets lOA-C of each panel 5 are joined in a dovetail arrangement. Construction and installation of the magnetic shield is simple.
- Pre-fabricated panels are bought to the site for installation.
- the panels 5 are attached to a wall using rivets (the head of the rivet being larger than the hole created).
- Panels 5 may be alternatively fixed to a framework consisting of plywood or wooden batons.
- the panels 5 can be bent or otherwise shaped to cover the wall to ceiling and/or wall to floor joints. Consequently, an entire room can have a magnetic shielding surround.
- more than one layer of panels 5 may be used to provide the required shielding
- Magnetic shields comprising panels 5 constructed in accordance with the present invention find particular application in rooms containing MRI scanners and rooms requiring transformer and substation shielding, communications protection, or transducer shielding. Also, laboratory or industrial settings containing sensitive equipment and measuring devices which may otherwise be affected by magnetic shields.

Abstract
L'invention porte sur un écran magnétique préfabriqué comprenant un panneau laminé doté d'au moins deux feuilles coplanaires possédant des propriétés de blindage électromagnétiques, les feuilles étant disposées et reliées de manière à être décalées les unes par rapport aux autres afin de créer une superposition le long du rebord de chaque feuille.
