Abstract

PURPOSE:To eliminate the propagation of vibration in the ground by burying a ferrite molding of a partition wall form in the ground between a seismic center and an object to be protected from earthquake. CONSTITUTION:A ferrite molding 3 of a partition wall form is buried under the ground between a seismic center 1 and an object to be protected from earthquake. The ferrite used is made of fine iron oxide powder a byproduct of steel- making industry, natural magnetite, or even ground ferrite recoveries being widely produced. A mixture of the ferrite moldings and a plastic material has excellent earthquake proofness and also excellent durability under the ground for a long period of time because the chemical change of the ferrite can be prevented by the plastic material.

The method of the present invention is disclosed to have a remarkable effect in eliminating vibration propagation in the ground, and the present invention is carried out based on the basic purpose that a ferrite-containing plastic plate exhibits a remarkable vibration-proofing effect. It is. The history of the development of ferrite chemistry used in the present invention is that ferrite, a substance made of ferric oxide and other metal oxides, has been extensively studied by many chemists and has shown remarkable progress. It is known as an absorbing magnetic material. Spinel ferrite, hexagonal ferrite, garnet ferrite, Bergzuka:, 4/
Many forms of ferrite, such as iron ferrite, are known from the academic field, but the ferrite used in the present invention is a naturally occurring magnetic iron, which is convenient and economical, or an iron oxide composition powder produced as a by-product in the iron and steel industry. is useful, but crushed ferrite recovered materials, which are widely produced, can also be used. The ferrite molded product of the present invention is made by molding the iron oxide composition with a sticky material or kneading it with plastic to form a pellet or plate shape, and the plastic may be polyethylene or polypropylene. , polyvinyl chloride, polystyrene, polyester, etc. The suitable form of the ferrite plastic of the present invention is 70% to 90% ferrite. and so on. When the ferrite molded product of the present invention is mixed with plastic, it has excellent weather resistance, the plastic has the effect of preventing chemical changes in ferrite, and it has the advantage of not changing even if it is buried underground for many years.
