Description
본 발명은 아파트나 건물 등에 설치되는 출입용 도어를 스포트 크린칭으로 결합된 출입용 도어의 문틀결합구조에 관한 것이다.The present invention relates to a door frame coupling structure of the access door coupled to the spot cleaning the door for access installed in the apartment or building.
일반적으로, 출입문은 방화문으로서의 역할을 담당하므로 화재시 화염의 전파를 차단시키기 위해 단열재를 내장한 철판으로 형성되어 있고, 상기 출입문을 지지하는 문틀도 역시 철제로 형성되어 있었다.In general, since the door plays a role as a fire door, it is formed of an iron plate with a heat insulating material to block the propagation of flames in case of fire, and the door frame supporting the door is also made of steel.
상기 문틀을 구성하는 수직과 수평부재중에 하부수평부재는 통행인이 출입시 밟고 지나가는 부분이어서 도색이 쉽게 벗겨지므로 도색이 필요 없고 외관이 깨끗한 스테인레스강을 주로 사용하며, 수직부재와 수평부재를 결합하여 문틀을 형성하기 위해서는 양 부재가 맞닿는 부분에 용접을 해야 한다.Among the vertical and horizontal members constituting the door frame, the lower horizontal member is a part passing by the passer-by when entering and exiting, so that the painting is easily peeled off. In order to form the two parts should be welded to the contact portion.
종래 문틀은 롤 포밍기(Roll Forming)를 이용하여 문틀의 형상을 갖도록 롤 포밍하는 방법과 철판 및 스텐판, 신주판 부재를 절단 절곡하여 접는 방식으로 문틀을 형성하였다.Conventional door frame was formed using a roll forming machine (Roll Forming) to form a door frame to have a shape of the door frame and to form a folding frame by cutting and bending the iron plate, stainless steel plate, new cast plate member.
또한, 문틀의 결합구조는 양 부재가 맞닿는 접촉부를 위에서 용접하는 방법을 사용하였기 때문에 용접자국이 남을 뿐만 아니라 열이 가해진 스테인레스판의 용접부인 접촉부 근처가 변색되어 미관을 해치는 문제점이 있었다.In addition, since the joining structure of the door frame uses a method of welding from above the contact portion where the two members contact each other, there is a problem that not only the welding marks remain but also the discoloration near the contact portion, which is the weld portion of the heated stainless plate, to damage the aesthetics.
또한, 상기와 같은 용접자국을 없애기 위하여 양 부재의 접촉부분을 밑으로부터 용접하는 방법도 사용되어 왔으나, 이렇게 할 경우 용접 건을 밑으로부터 수평부재 속으로 집어넣어서 접촉부를 용접해야 하므로 작업이 상당히 번거로울 뿐만 아니라 접촉부에 용접자국은 생기지 않으나 열에 의한 변색은 여전히 남게 되는 문제점이 있었다.In addition, a method of welding the contact portions of both members from the bottom has been used to remove the welding marks as described above, but in this case, the welding gun must be inserted into the horizontal member from the bottom to weld the contacts, which is quite cumbersome. In addition, there is a problem that the welding marks are not generated in the contact portion, but the discoloration due to heat still remains.
따라서, 본 발명은 상기의 문제점을 해결하기 위하여 이루어진 것으로써, 본발명의 목적은 전방절곡부와 후방절곡부의 외관상의 접촉부분을 용접하지 않으므로 용접자국이나 용접열에 의한 변색이 없으며 상호접촉부가 깨끗하게 유지되는 출입용 도어의 문틀결합구조를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, and the object of the present invention is not welding the external contact portion of the front bent portion and the rear bent portion, there is no discoloration due to welding marks or welding heat and keep the mutual contact portion clean. It is to provide a door frame coupling structure of the entrance door.
본 발명의 다른 목적은 하단부는 출입시에 문틀을 밟고 지나가야 하므로 중앙부의 문틀이 휘거나 찌그러지지 않도록 결합시 보강판이 삽입되는 구조를 갖도록 스포트 크린칭으로 결합된 출입용 도어의 문틀결합구조를 제공하는데 있다.Another object of the present invention is to provide a door frame coupling structure of the door for the door entrance coupled by spot-cleaning to have a structure in which the reinforcing plate is inserted so that the lower portion is to step on the door frame at the time of entry and exit so that the door frame is not bent or crushed. It is.
본 발명의 또 다른 목적은 전방절곡부와 후방절곡부를 견고하게 결합하고 결합시 제작단가와 시간을 단축할 수 있는 스포트 크린칭기로 결합된 출입용 도어의 문틀결합구조를 제공하는데 있다.Still another object of the present invention is to provide a door frame coupling structure of an entrance door coupled with a spot cleaning machine that can firmly couple the front bend and the rear bend and reduce the manufacturing cost and time at the time of coupling.
상기 목적을 달성하기 위하여 본 발명의 스포트 크린칭으로 결합된 출입용 도어의 문틀결합구조는 전방절곡부와 후방절곡부로 결합되는 문틀에 있어서, 상기 전방절곡부와 후방절곡부의 결합시 패킹삽입 공간부를 갖는 두 절곡부를 스포트 클리칭으로 압착하여 철판을 체결하여 결합한 것을 특징으로 한다.In order to achieve the above object, the door frame coupling structure of the entrance door coupled to the spot-cleaning of the present invention is the door frame coupled to the front bent portion and the rear bent portion, the packing insertion space when the front bent portion and the rear bent portion is combined It is characterized in that the two bent portions having a crimp by pressing to combine the iron plate.

예컨대, 본 발명은 상기 상술한 스포트 크린칭으로 결합된 출입용 도어의 문틀결합구조는 전방절곡부와 후방절곡부의 결합시 패킹삽입 공간부를 갖는 두 절곡부를 스포트 클리칭으로 압착하여 철판을 체결하여 결합한 것은 상기의 실시예의 출입용 도어의 문틀결합구조에 소파에만 국한하지 않으며, 청구범위에서 청구한 본 발명의 요지를 벗어남이 없이 본 발명이 속하는 기술분야에 통상의 지식을 가진 자라면 다양한 변형 실시가 가능한 것임은 물론이고, 그와 같은 변경은 본 발명의 청구범위내에 있게 된다.For example, the present invention is a door frame coupling structure of the door for doors coupled by the above-mentioned spot cleaning, the two bent parts having a packing insertion space portion when the front bent portion and the rear bent portion is combined by pressing the pressing clamping spot plate to combine the iron plate It is not limited to the sofa in the door frame combination structure of the entrance door of the above embodiment, and various modifications are possible to those skilled in the art without departing from the gist of the invention claimed in the claims. It goes without saying that such modifications are intended to be within the scope of the present invention.
상기에서 설명한 바와 같이. 본 발명의 스포트 크린칭으로 결합된 출입용 도어의 문틀결합구조는 두 판의 결합부분을 용접하지 않으므로 그 외부에 용접자국이 남지 않으므로 외관이 깨끗하고 부분열에 의한 재질이 변화하여 약화되는 재질의 변화가 없는 효과가 있다. 또한, 결합력이 강하고 결합시 시간을 단축할 수 있어 제작비용이 적게되는 뛰어난 효과가 있으므로 방화문 제조산업상 매우 유용한 발명인 것이다.As described above. The door frame coupling structure of the entrance door coupled by the spot-cleaning of the present invention does not weld the joint portions of the two plates, so no weld marks remain on the outside thereof, so the appearance is clean and the material changes due to the partial heat change. There is no effect. In addition, it is a very useful invention in the fire door manufacturing industry because the binding force is strong and can shorten the time when bonding has an excellent effect of reducing the manufacturing cost.
