Beschreibung
Zusammenfassung:	The present invention provides a dual-strength shop-absorbing fastening apparatus capable of adjusting the clearance of a non-welded fence to adjust the clearance by the elasticity for a change rate caused by contraction or expansion of a crossbar inserted to be fastened and fixed between post bosses of a post and to be tensioned again by the restoring force after being contracted for shock absorption in a collision by an external force applied to the crossbar. The dual-strength shop-absorbing fastening apparatus capable of adjusting the clearance of a non-welded fence comprises: a shop-absorbing member of an elastic material having a more extended length than the end of each post boss, and including a main shock-absorbing unit and an auxiliary shock-absorbing clearance adjustment unit having different thicknesses and strengths; and a flange bracket including a support flange provided on the end of the shock-absorbing member and coming in contact with the shock-absorbing member, and a fastening shaft provided on the support flange and inserted into the crossbar to be fastened to the crossbar. Accordingly, the present invention has the effect of preventing deformation of the post and the crossbar even for a change rage caused by contraction or expansion of the crossbar, the effect of securing high reliability for a product by preventing damage between the crossbar and the post even for an external force applied to the crossbar, and the effect of preventing secondary accidents. 본 발명은 지주의 지주보스 사이에 삽입되어 체결 고정되는 횡대의 수축 또는 팽창에 따른 변화율에 대하여 자체탄성에 의해 유격조절이 가능함은 물론 횡대에 가해지는 외력으로 인한 충돌에 대하여 완충작용인 수축 후 자체 복원력에 의해 다시 인장이 이루어질 수 있도록 각각의 지주보스의 끝단보다 더 연장된 길이를 가지며, 서로 다른 두께와 강도를 가지는 메인 완충부 및 보조 완충 유격조절부를 포함하는 탄성 재질의 완충부재; 및 상기 완충부재의 끝단에 그 완충부재와 맞닿는 지지플랜지, 상기 지지플랜지에 횡대의 내부로 삽입되어 횡대와 체결되는 체결 축을 포함하는 플랜지 브래킷;을 포함하는 무용접 펜스의 유격조절이 가능한 이중강도의 완충 체결장치를 제공한다. 그에 따라 횡대의 수축 또는 팽창에 따른 변화율에 대해서도 횡대 및 지주의 변형을 방지할 수 있는 효과와 함께 횡대에 가해지는 외력에 대해서도 지주와 횡대 간의 파손됨을 방지함에 따라 제품에 대한 높은 신뢰성을 확보할 수 있는 효과와 함께 2차적인 사고도 예방할 수 있는 효과를 가진다.
