Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、海上（空中を含む）で使用され、使用後は海
中に投棄される構造部材に関するものである。TECHNICAL FIELD The present invention relates to a structural member used on the sea (including in the air) and thrown into the sea after use.
例えば海上で射撃訓練を行う場合、その標的となる模擬
飛翔体は、砲弾が当たって使用不能になると、そのまま
海中に投棄される。For example, when performing shooting training on the sea, when the target simulated flight object is hit by a shell and becomes unusable, it is dumped into the sea as it is.
従来、このような模擬飛翔体の構造部材には例えば図−
３のような断面井桁形のアルミニウム合金押出型材１が
使用されている。この型材１の突条部２は翼など他の部
材を取り付けるのに使用される部分である。Conventionally, for example, the structural member of such a simulated flying object is shown in FIG.
An aluminum alloy extruded mold material 1 having a cross-shaped cross section as shown in No. 3 is used. The ridge portion 2 of the mold material 1 is a portion used for attaching other members such as wings.
このような構造部材は長さが数メートルもあるため、こ
れがそのまま海中に投棄され、海底に沈んでいると、後
で漁船の底引き網などがこれを引っ掛け、漁網を切断す
る事故が発生するおそれがある。Since such a structural member is several meters long, if it is dumped into the sea as it is and sinks to the seabed, there is a risk that a fishing boat's bottom seine or the like may catch it later and cut the fishing net. is there.
本発明の目的は、上記のような課題を解決するため、海
中に投棄されても漁網を切断することのない構造部材を
提供することにある。In order to solve the above problems, an object of the present invention is to provide a structural member that does not cut the fishing net even if it is dumped into the sea.
この目的を達成するため本発明は、海中に投棄される構

成したことを特徴とする。In order to achieve this object, the present invention comprises a structural member to be dumped in the sea, which is fixed to a magnesium or magnesium alloy extruded pipe material with mounting members made of aluminum or aluminum alloy at appropriate intervals in the longitudinal direction. It is characterized by having done.

網を切断するおそれがなくなる。With such a configuration, the magnesium or magnesium alloy extruded pipe material is corroded and dissolved by seawater after being dumped into the sea, so that only the relatively short aluminum or aluminum alloy mounting member remains and the fishing net is cut. There is no fear.

寸法精度の出しやすいアルミニウム又はアルミニウム合
金製の取付け部材を固定すれば、所期の寸法精度を有す
る構造部材を構成することができる。It was also considered to construct the entire structural member with magnesium or magnesium alloy extruded shape material, but it is difficult to straighten the magnesium or magnesium alloy extruded shape material, and the straightness of the part corresponding to the protruding part of the well girder is straightened. It turned out that I couldn't. On the other hand, the magnesium or magnesium alloy extruded pipe material does not have a ridge, so that twist straightening is unnecessary and straightening is easy. Therefore, if a mounting member made of aluminum or an aluminum alloy, which is easy to obtain dimensional accuracy, is fixed to this, a structural member having desired dimensional accuracy can be constructed.
以下、本発明の実施例を図面を参照して詳細に説明す
る。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

たアルミニウム合金製の取付け部材である。1 and 2 show a structural member according to an embodiment of the present invention. In the figure, 3 is a magnesium alloy extruded pipe material,
Reference numeral 4 denotes a mounting member made of an aluminum alloy, which is fixed to the pipe member 3 with an appropriate interval in the longitudinal direction.
マグネシウム合金押出管材３は表面平滑であるため、ね

のを作ることは容易である。Since the magnesium alloy extruded pipe material 3 has a smooth surface, no twist straightening is necessary, and a straight product can be easily obtained by ordinary straightening. On the other hand, the mounting member 4 is obtained by cutting an aluminum alloy extruded material into a predetermined length. Aluminum alloy extruded shape materials have been produced in various shapes from the past, and it is easy to manufacture materials with high dimensional accuracy.

網を切断するおそれがないという利点がある。As is clear from the above description, the structural member according to the present invention has a structure in which the mounting members made of aluminum or aluminum alloy are fixed to the magnesium or magnesium alloy extruded pipe material at appropriate intervals, and therefore, when it is dumped into the sea. The magnesium or magnesium alloy extruded pipe material is melted by the corrosive action of seawater, leaving only a short attachment member afterward, and there is an advantage that even if the fishing net is caught on the fishing net, the fishing net will not be cut.
