본 고안은 공사장에서 기준점을 파악하기 위해 주로 사용하는 원추의 개량에 관한 것으로써 보다 구체적으로 설명하면, 원추형 하체의 상단에 돌출매립부를 형성하여 그 외주에 합성수지제로 형성되는 상체를 피복하므로써 생산원가를 절감시키고, 원추형심체를 주물제가 아닌 압연강제로 형성하여 충돌시 파손되는 일이 없게할 것이다.The present invention relates to the improvement of the cone mainly used to identify the reference point in the construction site, and more specifically, the production cost by covering the upper body formed of synthetic resin on the outer periphery by forming a protruding buried portion at the top of the conical lower body. It will reduce and form conical core in rolled steel, not cast, so that it will not be damaged in the event of a collision.

종래의 원추는 주철제로 성형이 되어서 충돌시에 쉽게 깨어저서 내구성이 없는 결점이 있었고, 주조제법이므로 정밀한 제작이 어려우며, 가격도 고가로 되는 결점이 있었다.Conventional cones are molded of cast iron and easily broken at the time of collision, which has no drawbacks, which are not durable.

본 고안은 위와같은 종래의 결점을 시정하기 위하여 안출한 것으로 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention has been devised to correct the above-described drawbacks and will be described in detail with reference to the accompanying drawings.

압연강제로된 원추형 하체(1)의 상부로 매립돌출봉(2)을 형성하여 상단에 나사공(5)이 있는 단관부(4)를 돌착하고, 돌출봉(2)의 외주에 환상요입홈(3)을 형성시켜 원추형 하체(1)의 상단 둘래에서 돌출단관부(4)에 이르도록 원추형으로 되는 합성수지제 상체(9)를 사출성형 방법으로 피복하여 일체가 되도록 한 구조이다.A buried protrusion bar 2 is formed on the upper portion of the conical lower body 1 made of rolled steel, so that the end pipe part 4 having a screw hole 5 is attached to the upper end, and an annular recess groove is formed on the outer circumference of the protruding bar 2. (3) is formed so as to be integrally coated with a synthetic resin upper body 9 which becomes conical to reach the protruding end pipe part 4 from the upper end of the conical lower body 1 by an injection molding method.

이와같이된 본 고안은 원추몸통을 구성함에 있어서 하반체(1)과 매립부(2)는 압연강제로 만들어지고, 상반체는 합성수지제(9)로 형성되기 때문에 외형이 아름다우면서도 정밀하고 튼튼하게 될뿐 아니라, 충격을 받아도 쉽게 파손되지 않는 이점이 있고, 매립부(2)둘레에 환상요입홈(3)이 있어서 합성수지제 상체(9)가 사출형성될때 견고히 밀착되어 사용중에 분리될 염려가 없으며, 규격 생산으로 량산이 되므로 생산가격이 낮아지고 실용적인 장점이 있는 것이다.In the present invention, the lower half body 1 and the buried portion 2 are made of rolled steel, and the upper half body is made of synthetic resin 9, so that the outer body 1 and the buried part 2 are formed in a conical body. In addition, there is an advantage that it is not easily broken even when impacted, and there is an annular recess groove 3 around the buried portion 2 so that when the synthetic resin upper body 9 is injection-molded, there is no fear of being separated during use. As a result, the production price is lowered due to mass production, which has practical advantages.

Claims

As shown in the figure, the buried protrusion bar 2 is formed on the upper portion of the conical lower body 1 made of rolled steel, and the end pipe part 4 having the screw hole 5 is attached to the upper end, and the protruding rod 2 is formed. Conical to form an annular groove (3) on the outer periphery of the conical lower body (1) to cover the upper body (9) made of a conical shape so as to reach the end pipe portion (4) by injection molding method (Iii).
