Title:
RADIO-WAVE ABSORBING WALL
Document Type and Number:
Japanese Patent JP3641025
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To give adhesion with mortar to ferrite tile itself by forming stepped sections retreating from a front from the direction of radio-wave arrival at both end sections in the electric-field direction of the ferrite tile respectively.
SOLUTION: In a ferrite tile 11, stepped sections 13 are formed at both end sections in the electric-field direction of arrival radio waves respectively, and a cross section in the electric-field direction is formed in a convex shape. The ferrite tiles 11 are arranged on the fronts of reinforcements 2 forming metallic reflecting meshes in a continuous manner in the magnetic-field direction and in a discontinuous manner in the electric-field direction, the fronts of the ferrite tiles 11 are covered with facing tiles 20, and concrete 4 is placed on the rear sides and the reinforcements 2, the ferrite tiles 11 and the facing tiles 20 are unified. Voids among the facing tiles 20 are filled with joint fillers 22. Concrete 4 enters the stepped sections 13 of the ferrite tiles 11 at that time, and the falling of the ferrite tiles 11 is prevented while the contact areas of the rears of the facing tiles 20 and concrete 4 are increased.
