Description
제1도는 본 고안의 일부 절결한 전체 사시도.1 is a partially cut-away perspective view of the present invention.
제2도는 본 고안의 조립상태를 예시한 종단면도.Figure 2 is a longitudinal cross-sectional view illustrating the assembled state of the present invention.
제3도는 본 고안의 사용상태도.3 is a state of use of the present invention.
본 고안은 짧은 지주를 사용처에 따라 여러개 연결하여 긴 지주를 견고하게 조립하는 합성수지재 지주에 관한 것이다. 종래 조립식 지주는 합성수지 공업의 발달과 더불어 합성수지가 가볍고 부폐성이 적으며 사출등 성형 가공성이 좋은 점과 더불어 원가를 월등히 절감할 수 있음으로 해서 여러 방면의 조립공사에 합성수지를 많이 사용되어 있으나 실제에 지주를 조립 연결하여 사용한 결과 지지력이나 감착력등 기계적 강도가 약하여 지구성이 적고 쉬 파괴되는 등 결점을 면치 못하였다.The present invention relates to a synthetic resin strut which firmly assembles a long strut by connecting several short struts according to the use place. Conventional prefabricated struts are made of synthetic resins with light weight, less encapsulation, good molding processability such as injection molding, and can greatly reduce costs. As a result of assembling and using the strut, the mechanical strength such as supporting force and adhesive force was weak, resulting in low endurance and breakage.
본 고안은 이와같은 결점을 시정하기 위하여 합성수지 환봉체내에 철관을 매설하여 봉체의 강도를 월등히 높히고 연결부의 감합부를 여러단으로 형성하여 연결부를 보강하고 감착도를 높인 것으로서 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention embeds an iron tube in a synthetic resin round rod to remedy such defects, which greatly increases the strength of the rod and forms a fitting portion of the connecting portion in multiple stages, thereby reinforcing the connecting portion and increasing the degree of adhesion. The explanation is as follows.
내부에 철관(2)을 매설 피복한 합성수지 환봉체(1)의 일단에 철관 첨단이 노출된 돌부(4)와 합성수지 피복층에 단설된 단환층(5)으로 감착돌부(3)를 형성하고 타단에는 합성수지 피복층 내주벽에 단락층(7)(8)을 단설하여 감착돌부(3)가 감착되게 감착요부(6)를 형성하여서된 것이다.On one end of the synthetic resin round bar (1) with the steel pipe (2) embedded therein, a sensation protrusion (3) is formed by the protrusion (4) with the iron pipe tip exposed and the monocyclic layer (5) installed on the synthetic resin coating layer. The shorting layers 7 and 8 are provided on the inner circumferential wall of the synthetic resin coating layer to form the fitting recesses 6 so that the fitting protrusions 3 are attached.
이와같이 본 고안은 철관(2)을 합성수지 환봉체(1) 내벽에 매설 피복하였음으로 우수에 대하여 부폐성이 없는 합성수지 재질의 장점을 살리는 동시에 환봉체(1)의 기계적 강도를 높여주며 감착연결부를 다단으로 하여 환봉체(1')의 철관(2)의 첨단은 합성수지 피복층의 후육부 단락층(8)에 감합되게 하므로서 감합부가 보강되고 감합부 단락층(7)과 환봉체(1')의 단환층(5')의 접촉면은 마찰률이 높은 합성수지의 피막층이 서로 접하는 곳으로서 감착부의 탈락이 방지되여 견고하게 감착 연결된다.In this way, the present invention is to cover the steel pipe (2) to the inner wall of the synthetic resin ring (1) to improve the mechanical strength of the round bar (1) at the same time, while utilizing the advantages of the synthetic resin material that is not non-binding for excellent As a result, the tip of the iron pipe 2 of the round bar body 1 'is fitted to the thick-circuit short layer 8 of the synthetic resin covering layer so that the fitting part is reinforced and the ring part 1 and the round bar body 1' are monocyclic. The contact surface of the layer 5 'is a place where the coating layers of the synthetic resin having a high friction rate are in contact with each other, thereby preventing the dropping of the fitting portion, thereby being firmly attached and attached.
본 고안은 이와같은 구조임으로 보관, 운반이 편리하고 기계적 강도가 높으며 연결이 견고한 합성수지제 조립식 지주를 염가로 제공하는 효과가 있다.The present invention has the effect of providing a prefabricated prefabricated strut made of synthetic resin that is easy to store and transport, has high mechanical strength, and has a strong connection.
