본 발명은 철문(鐵門)의 상단 및 하단에 접합되는 철문용 단부(端部)마감부재에 관한 것으로, 힌지브래킷(Hinge bracket)이 체결되는 부분의 단부마감부재에 프레싱을 통하여 요부(凹部)를 형성하고, 이 요부에 나사공이 형성된 보강판을 부착함으로써, 해당 부위의 강도를 보강함과 동시에 힌지브래킷 체결을 위한 나사선의 길이를 확장하여 철문과 피버트힌지(Pivot Hinge)의 견고한 결합이 이루어지도록 한 것이다.The present invention relates to an end finishing member for a metal door which is joined to the upper and lower ends of a iron gate. The end finishing member of the portion to which the hinge bracket is fastened is press- By attaching a reinforcement plate having a screw hole to the recess, the strength of the portion is reinforced, and the length of the thread for tightening the hinge bracket is extended to securely connect the iron door and the pivot hinge .

각종 건축물의 출입문 또는 방화문(防火門) 등으로 사용되는 철문은 통상적으로 도 1에서와 같이, 강철판을 절곡하여 철문본체(40)를 구성하고, 내부에 강도 보강 등을 위한 허니컴(Honeycomb)구조체를 설치한 후, 상하 양단에 단부마감부재(30)를 접합하여 완성하게 되며, 단부마감부재(30)가 접합된 상, 하단에 피버트힌지(Pivot Hinge)를 설치하거나, 철문본체(40) 측면에 경첩을 부착하여 프레임(49)에 결합함으로써 출입문을 구성하게 된다.As shown in FIG. 1, a steel door used as an entrance door or fire door of various buildings is generally constructed by bending a steel plate to form a steel door main body 40, and a honeycomb structure A pivot hinge is provided at the upper and lower ends where the end closure member 30 is joined or the upper and lower ends of the iron door main body 40 And the hinge is attached to the frame 49 to constitute a door.

철문본체(40)의 상, 하단에 접합되는 단부마감부재(30)는 강철 등의 금속판으로 그 폭과 길이가 철문의 단면과 일치하도록 형성되며, 통상 금속판을 U자형으 로 절곡하여 양측에 측벽을 형성하고 이들 측벽과 철문본체(40)간에 스폿(Spot)용접 등의 용접을 실시하여 접합되게 되는데, 이 단부마감부재(30)에 나사공을 형성하고 볼트(23)를 이용하여 힌지브래킷(22)을 체결함으로써 철문을 프레임(49)에 설치하게 된다.An end closing member 30 joined to the upper and lower ends of the iron gate main body 40 is a metal plate made of steel or the like whose width and length coincide with the end face of the iron door and is usually formed by bending a metal plate into a U- And a spot welding or the like is performed between these side walls and the iron door main body 40 to form a screw hole in the end closing member 30. The bolt 23 is used to form a hinge bracket 22 are fastened to the frame 49 so as to install the iron door.

이렇듯 단부마감부재(30) 자체에 나사공이 형성되는 경우에는 나사선의 길이가 짧을 수 밖에 없었고, 따라서 힌지브래킷(22)과의 체결강도도 낮을 수 밖에 없었다.In the case where a threaded hole is formed in the end closure member 30 as described above, the screw thread has to be short in length, and therefore, the fastening strength with the hinge bracket 22 has been low.

또한, 단부마감부재(30)의 나사공 주변은 철문의 하중이 집중되고 철문이 개폐됨에 따라 반복적인 외력과 충격이 가해지는 부분이나, 이에 대한 별도의 보강조치가 없을 뿐 아니라, 나사공의 형성으로 인한 단면감소로 오히려 구조적인 취약부로서 작용하게 되어 철문의 안정성 및 내구성을 저해하는 요인이 되었다.In addition, since the load of the iron door is concentrated and the iron door is opened and closed, the external periphery of the end closure member 30 is subjected to repetitive external force and shock, and there is no additional reinforcement action, Which is caused by the reduction of the cross section due to the structural weakness of the door and has become a factor to hinder the stability and durability of the iron gate.

따라서, 이러한 문제점을 해결하기 위하여, 단부마감부재(30)외에 별도의 보강판(10)을 구성하여, 힌지브래킷(22)의 체결작업시 단부마감부재(30)와 힌지브래킷(22)사이에 삽입한 후 체결하는 방법 등이 사용되고 있으나, 작업과정이 복잡할 뿐 아니라, 대부분의 나사 체결력은 힌지브래킷(22)과 보강판(10)사이에 작용하게 되므로, 보강판(10)이 단부마감부재(30)에서 쉽게 이탈되는 문제점이 있었다.In order to solve this problem, an additional reinforcing plate 10 may be formed in addition to the end closure member 30 so as to be disposed between the end closure member 30 and the hinge bracket 22 during the fastening operation of the hinge bracket 22. [ The reinforcing plate 10 is inserted between the hinge bracket 22 and the reinforcing plate 10 so that the reinforcing plate 10 can be inserted into the end closing member 30. [ (30).

한편, 보강판(10)을 단부마감부재(30)에 미리 부착하되 힌지브래킷(22)과의 접합면 이면에 부착하는 방법을 생각할 수 있으나, 이 또한 철문본체(40) 내부의 허니컴(Honeycomb)구조체를 잘라내야 하는 등의 문제점이 있다.A method of attaching the reinforcing plate 10 to the end closure member 30 in advance and attaching the reinforcing plate 10 to the back surface of the joining surface with the hinge bracket 22 can be considered. However, the honeycomb inside the iron door main body 40, There is a problem of cutting the structure.

본 발명은 전술한 문제점을 감안하여 창안한 것으로, 힌지브래킷(Hinge bracket)(22)이 체결되는 부분의 단부마감부재(30)에 프레싱을 통하여 요부(凹部)를 형성하고, 이 요부에 나사공(11)이 형성된 보강판(10)을 부착함으로써, 해당 부위의 강도를 보강함과 동시에 힌지브래킷(22) 체결을 위한 나사선의 길이를 확장하여 철문과 피버트힌지(Pivot Hinge)의 견고한 결합이 이루어지도록 한 것이다.SUMMARY OF THE INVENTION The present invention has been developed in view of the above-described problems, and it is an object of the present invention to provide a hinge bracket, which is formed by pressing a portion of an end closure member at a portion where a hinge bracket is fastened, The reinforcing plate 10 on which the reinforcing plate 11 is formed is reinforced so that the strength of the reinforcing plate 10 is reinforced and the length of the thread line for engaging the hinge bracket 22 is extended to form a rigid connection between the iron door and the pivot hinge .
