방화문{Fire Door}Fire Door {Fire Door}

본 발명은 방화문에 관한 것으로, 더욱 상세하게는 내열성과 강성을 크게 향상시켜 화재 발생시나 도난을 위해 공구로 철판부재 틈새를 강제로 벌어지게 하는 경우에도 변형되거나 파손되는 것을 방지할 수 있도록 하여 제품의 신뢰성을 향상시킬 수 있도록 한 방화문에 관한 것이다.
More particularly, the present invention relates to a fire door, and more particularly, to a fire door which is improved in heat resistance and rigidity to prevent deformation or breakage even when a gap between the iron plate members is forcibly opened with a tool To a fire door that can improve reliability.

일반적으로, 아파트나 가정 및 사무실 등의 현관에는 화재가 발생할 경우, 화염의 전파를 방지 또는 차단할 목적으로 금속재로 이루어진 방화문을 설치하고 있다.Generally, a fire door made of a metal material is installed on an entrance of an apartment, a home, or an office in order to prevent or prevent the spread of a fire when a fire occurs.

상기 방화문은 벽멱에 설치되는 방화문용 문틀후레임에 피봇힌지 또는 경첩을 이용하여 회전 가능하게 장착되며, 상기 문틀후레임도 금속재의 판재로 제작된다.The fire door is rotatably mounted on a door frame for a fire door using a pivot hinge or a hinge, and the door frame is made of a metal material.

종래, 일반적으로 건축물의 출입구에 방화문을 설치하는 구조는 방화문 본체(100)가 개폐 가능하게 하면서 그 외부를 감싸는 크기의 문틀후레임(200)을 건축물의 출입구를 이루는 벽체에 고정시키고, 문틀후레임(200)과 방화문 본체(100)의 사이에는 힌지(300)를 설치하게 된다.2. Description of the Related Art [0002] In general, a fire door is installed in a doorway of a building. The fire door is opened and closed while a door frame 200 having a size to enclose the door frame is fixed to a wall of the door. And the hinge 300 is installed between the main body 100 and the main body 100 of the fire door.

그리고, 소음방지와 단열 및 개폐시 완충을 위해 문틀후레임(200)과 방화문 본체(100) 사이의 접촉부분에는 우레탄소재의 가스켓부재(400)가 다수 설치하기도 한다.A plurality of urethane gasket members 400 may be provided at the contact portion between the door frame 200 and the fire door main body 100 for noise prevention, insulation, and buffering during opening and closing.

따라서, 가스켓부재(400)에 의해 방화문 본체(100)와 문틀후레임(200) 사이의 틈새가 밀폐되어 외부에서 화재발생시 화재로 인한 유해가스가 실내로 유입되는 것을 차단하는 효과와, 방화문 본체(100)가 닫히면서 문틀후레임(200)과 부딪쳐 발생되는 소음을 방지하는 효과가 있으며, 또한 외부공기와 내부공기를 차단시켜 실내 단열효과를 얻을 수 있다.Therefore, the gap between the fire door main body 100 and the door frame 200 is sealed by the gasket member 400, thereby preventing the noxious gas from entering the room due to the fire when the fire occurs from the outside, Is closed to prevent noise generated when the door frame 200 collides with the door frame 200. In addition, it is possible to block the outside air and the inside air to obtain an indoor heat insulating effect.

또, 방화문 본체(100)는 일정두께의 금속판재로 성형되는데 전면을 이루는 외측부재(120)과, 이 외측부재(120)의 후측으로 간격을 두고 위치하여 방화문 본체(100)의 후면을 이루는 내측부재(110)로 구성되어 있다.
The fire door main body 100 is formed of a metal plate having a predetermined thickness and includes an outer member 120 forming a front face and an inner side wall 120 spaced from the rear side of the outer member 120 and forming a rear side of the fire door main body 100 And a member (110).

대한민국 특허 등록번호 10-0766199호(2007년10월04일 등록)Korea Patent Registration No. 10-0766199 (Registered on October 04, 2007) 대한민국 실용신안 등록번호 20-305989(2003년02월18일 등록)Korea Utility Model Registration No. 20-305989 (Registered February 18, 2003)

상기와 같이 종래 방화문의 구성은 방화문 본체가 외측부재(120)와 내측부재(110)로 이루어지되, 상기 외측부재(120)의 단부와 내측부재(110)의 단부는 벤딩프레스기에 의해 단면상 내측부재의 단부가 외측부재의 단부를 감싸는 방식으로 이음부가 갖춰지고, 상기 이음부에는 등 간격으로 점용접방식인 스폿트 용접에 의해 일체를 이루고 있다.The end portion of the outer member 120 and the end portion of the inner member 110 are connected to each other by a bending press machine so that the end face of the inner member 110, The end portion of the outer member is wrapped around the end portion of the outer member, and the joint portion is integrally formed by spot welding which is a spot welding method at equal intervals.

상기 방화문 본체의 경우, 단열을 위해 내부에 단열재(난연소재인 유리섬유로 재작되는 허니컴)를 채우는 것이 일반적이기는 하나 그 외곽은 전부 금속판재로 이루어져 있다.In the case of the main body of the fire door, it is common to fill the inside with a heat insulator (a honeycomb made of glass fiber, which is a flame retardant material) for heat insulation, but the outside is entirely made of a metal plate material.

한편, 상기 방화문 본체(100)는 도 1 및 도 2에서 도시한 바와 같이 힌지(300)가 설치되는 실내측에는 외측부재(120)와 내측부재(110)의 일부가 벤딩프레기를 통해 서로 겹쳐지게 하면서 스폿용접(점용접)에 의해 일체를 이루게 된다.1 and 2, in the interior of the main body 100 of the fire door 100, a part of the outer member 120 and the inner member 110 are overlapped with each other through a bending press on the inner side where the hinge 300 is installed And they are formed integrally by spot welding (spot welding).

또, 힌지(300)가 설치되는 타측 방화문 본체(100)는 내측부재(110)를 외측부재(120)의 단부가 절곡 절첩되어 감싸지는 상태로 날개부가 갖춰지면서 가스켓부재(400)와 접하게 되는데, 상기 날개부 위치의 내측부재(110)와 외측부재(120) 또한 등간격으로 스폿용접을 통한 점용접에 의해 접합되어 있다.The other side door door body 100 in which the hinge 300 is installed is in contact with the gasket member 400 while the inner member 110 is folded and folded at the end of the outer member 120, The inner member 110 and the outer member 120 at the wing portion are also jointed by spot welding at equal intervals.

이와 같이 2개로 분할된 내측부재(110)와 외측부재(120)의 스폿용접(W) 접합부는 단순히 벤딩결합과 점용접에 의해 일체를 이루고 있으므로 화재시 고열인 화기에 의한 압력에 대한 지지강도가 취약하다.Since the spot welding (W) junction of the inner member 110 and the outer member 120 divided into two is formed by the bending connection and the spot welding, the supporting strength against the pressure generated by the fire caused by the fire weak.

따라서, 화재 발생시 밀폐된 실내 온도가 높아지는 경우 스폿용접(W) 위치에서 결합력이 상실되면서 방화문 본체(100)가 파손되는 경우가 흔하게 발생되고 있는 실정이다.Therefore, when the sealed room temperature becomes high at the time of fire occurrence, the bonding force is lost at the spot welding (W) position, and the fire door main body 100 is often broken.

이러한 문제점을 위해 방화문의 안전 규범에서는 2000도 이상의 고온에서도 변형이나 파손되지 않는 것을 규정하고 있으나, 종래 벤딩결합과 스폿용접(W)에 의한 접합부의 경우 이 규정을 현실적으로 만족시키지 못하고 있다.In order to solve this problem, the safety standard of the fire door stipulates that even at a high temperature of 2000 degrees or more, it is not deformed or damaged. However, in the case of a conventional joint by bending and spot welding (W)

한편, 상기 방화문은 벤딩결합과 스폿용접으로 내측부재(110)와 외측부재(120)를 접합하는 경우, 두 금속판의 경계 틈으로 날카로운 공구를 강제 압입시키면, 경계 틈이 점차 벌어지면서 쉽게 변형되거나 파손되어 도난방지기능을 다하지 못하는 문제점이 있었다.Meanwhile, when the inner member 110 and the outer member 120 are joined by bending and spot welding, when the sharp tool is forcedly inserted into the gap between the two metal plates, the boundary gap gradually spreads, Thereby preventing theft prevention function from being performed.

또한, 스폿용접(W)은 방화문 본체(100)의 분체도장 후에도 용접부분이 미세하게 남아 있거나 그 위치에서 쉽게 부식이 발생되는 원인이 되어 상품성이 저하되고 결과적으로 제품에 대한 신뢰성이 떨어지는 문제점이 있었다.In addition, the spot welding W causes the welding portion to remain fine after corrosion of the powder coating of the fire door main body 100 or to easily cause corrosion at the position, resulting in a deterioration of the merchantability and the reliability of the product is deteriorated .

상기와 같은 종래의 방화문이 지닌 제반 문제점을 개선하기 위하여 본 발명은 접합부분에 대한 강성을 향상시키고, 특히, 고열에 의한 압력에도 변형 및 파손을 미연에 방지하여 안전 규정에도 적합하도록 한 방화문을 제공하는 데 목적이 있다.In order to solve the problems of the conventional fire door, the present invention improves the rigidity of the joint portion and particularly provides a fire door that is suitable for safety regulations by preventing deformation and breakage even with high temperature pressure The purpose is to do.

또한, 본 발명의 다른 목적은 결로현상과 기밀성 및 차음성을 확보할 수 있도록 하여 제품의 신뢰성과 상품성을 향상시키도록 한 방화문을 제공하는 데 있다.
It is another object of the present invention to provide a fire door which is capable of ensuring condensation, airtightness and sound insulation so as to improve the reliability and merchantability of the product.

상기한 바와 같은 목적을 달성하기 위하여, 본 발명은 속이 빈 상태의 문짝형상으로 내측부재(110)와 외측부재(120)가 절곡 성형되고 내부로 단열재(150)가 채워지는 방화문 본체(100)에 있어서,In order to achieve the above object, the present invention provides a fire door main body 100 in which an inner member 110 and an outer member 120 are folded and formed in a hollow shape, and the heat insulating material 150 is filled therein As a result,

상기 내측부재(110) 및 외측부재(120)는 양쪽 측면부 위치로 각각 중첩되게 하여 리벳(500)으로 수곳에서 각각 체결 고정시키고, 방화문 본체(100)의 양쪽 측면부 내측에는 보강부재(600)가 더 설치되는 것에 의해 달성된다.The inner member 110 and the outer member 120 are fixed to each other at a plurality of places by rivets 500 so as to be overlapped with each other at both side positions and a reinforcing member 600 is provided inside each side surface of the fire door main body 100 And is installed.

여기서 상기 내측부재(110)에는 문틀후레임(200)의 내측으로 오목하게 된 요홈부(210)에 가스켓(230)을 설치하고, 이 가스켓(230)에 밀착하기 위한 날개부(130)를 일체로 연장 절곡시켜서 성형된다.The inner member 110 is provided with a gasket 230 in a recessed groove 210 recessed inwardly of the door frame 200 and a wing 130 for tightly contacting the gasket 230 integrally And is formed by extrusion bending.

상기 보강부재(600)는 리벳(500)을 수용할 수 있는 공간인 작업공간부(610)가 길이방향으로 형성되어 있다.The reinforcing member 600 has a work space 610 formed therein in a longitudinal direction to accommodate the rivets 500.

이 보강부재(600)는 내측부재(110) 및 외측부재(120)의 두께보다 상대적으로 더 두꺼운 금속재로 대략 M 형상으로 절곡 성형된다.The reinforcing member 600 is bent and formed into a substantially M shape with a metal material that is relatively thicker than the thicknesses of the inner member 110 and the outer member 120.

이때, 이 보강부재(600)에는 수개의 비드홈(620)이 길이방향으로 성형되어 있다.
At this time, several bead grooves 620 are formed in the reinforcing member 600 in the longitudinal direction.

상기와 같은 본 발명의 방화문은 외측부재의 단부에 보강부재가 점접합을 이루고 외측부재의 단부를 내측부재의 단부가 감싸면서 다수의 리벳에 의해 일체를 이루게 됨으로써, 화기에 의한 압력에 대응할 수 있는 강성이 향상된다.In the fire door of the present invention as described above, the reinforcing member is point-bonded to the end portion of the outer member and the end portion of the outer member is integrally formed by a plurality of rivets while the end portion of the inner member is wrapped, Rigidity is improved.

따라서, 화재시 고열에 의한 압력이 발생되더라도 방화문의 변형 및 파손을 방지할 수 있어, 제품 안전 규정을 충족시킬 수 있는 효과가 있다.Therefore, it is possible to prevent the fire door from being deformed and damaged even if a pressure due to high temperature is generated in a fire, thereby satisfying the product safety regulations.

또, 외측부재의 단부 내주면과 일체를 이루고 있는 보강부재와 등 간격을 이루는 다수의 리벳에 의한 강성이 확보된다. Further, rigidity is secured by a plurality of rivets equally spaced from the reinforcing member integral with the inner circumferential surface of the end portion of the outer member.

특히, 외부인(절도목적의 침입자)이 절도를 목적으로 공구를 이용해 방화문의 틈새를 강제로 벌려 방화문을 변형 파손시키고자 하는 외부 압력에 대한 강성도 확보할 수 있는 효과가 있으며, 또한, 제조 과정에서 외측부재와 내측부재를 별도로 분체도장 작업을 하고 리벳작업을 할 수 있으므로 작업성이 향상되어 생산성을 향상시키는 효과가 있다..Particularly, there is an effect that an external person (intruder for theft) can secure the rigidity against the external pressure to deform the fire door by forcibly opening the gap of the fire door by using the tool for the purpose of theft, Since the member and the inner member can be separately powder coated and riveted, the workability is improved and the productivity is improved.

그리고, 분체 도장 후에도 도장부위가 변형되거나 부식되는 경우도 미연에 방지할 수 있고, 결로현상과 기밀성 및 차음성도 확보할 수 있어 제품의 신뢰성과 상품성을 향상시킬 수 있는 효과가 있다.
Also, it is possible to prevent deformation or corrosion of the painted portion even after the powder coating, and to prevent the condensation phenomenon, the airtightness and the difference in soundness, thereby improving the reliability and merchantability of the product.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 및 도 2는은 종래 방화문 구성을 도시한 단면도이다.1 and 2 are sectional views showing a conventional fire door structure.

도 3 내지 도 7은 본 발명이 적용된 방화문 구조를 도시하고 있다.3 to 7 show a fire door structure to which the present invention is applied.

상기 방화문 본체(100)는 내부로 속이 빈 공간을 가지며 전체적으로 문짝 형상을 갖도록 내측부재(110)와 외측부재(120)가 측면 위치에서 서로 중첩된 상태로 결합되고, 내부에는 단열재(150)가 채여지게 된다.The inner and outer members 110 and 120 are coupled to each other in a side position so that the door member 100 has a hollow space therein and has a door shape as a whole. .

상기 문틀후레임(200)은 방화문 본체(100)의 외곽을 감싸며 건축물에 고정 설치되는데, 방화문 본체(100)의 내측부재(110)의 접촉부 위치로는 오목하게 요홈부(210)을 파내게 된다.The door framing frame 200 is fixed to the building and surrounds the exterior of the fireproofing door body 100. The door frame frame 210 is recessed at the contact position of the inner member 110 of the fireproofing door body 100.

그리고, 이 요홈부(210)에는 문틀후레임(200)과 방화문 본체(100) 사이를 단열시킴과 아울러 기밀성과 차음성을 갖도록 하기 위해 고무재의 가스켓(230)이 설치된다.The gasket 230 of the rubber material is installed in the recessed portion 210 to insulate the door frame 200 and the fire door main body 100 from each other and have airtightness and sound insulation.

방화문 본체(100)는 힌지(300)에 의해 문틀후레임(200)으로부터 개폐가능하게 연결 설치되며, 문틀후레임(200)에는 사춤이 채워지게 된다.The fire door main body 100 is connected to the door frames 200 by means of a hinge 300 so as to be openable and closable, and the door frame frame 200 is filled with sand dancing.

방화문 본체(100)의 내부 공간으로는 허니컴을 포함한 단열재를 채우게 된다.The interior space of the fire door main body 100 is filled with a heat insulating material including honeycomb.

이와 같은 구조의 방화문 본체(100)는 내측부재(110) 및 외측부재(120)로 분할된 두 개의 금속판재로 절곡 성형되는데, 양쪽 측면부 위치로는 각각 서로 중첩되게 한 후, 리벳(500) 설치를 위해 우선 리벳(500)의 직경과 설치 간격을 감안하여 구멍들을 관통시키게 된다.The fire door main body 100 having such a structure is bent and formed by two metal plates divided into an inner member 110 and an outer member 120. The two side wall portions are overlapped with each other, The diameter of the rivet 500 and the spacing between the rivets 500 are taken into consideration.

그리고, 뚫어진 구멍들의 위치로 리벳(500)을 체결하기 위한 리벳팅 작업을 각각 수행하게 된다.Then, a riveting operation is performed to fasten the rivet 500 to the positions of the drilled holes.

한편, 방화문 본체(100)의 양쪽 측면부 내측 둘레를 따라 보강부재(600)를 설치하게 된다.On the other hand, the reinforcing member 600 is installed along the inner circumference of both side portions of the fire door main body 100.

이 보강부재(600)는 내측부재(110) 또는 외측부재(120)에 접촉된 상태로 스폿용접의 방법으로 유동되지 않도록 위치 고정시키는 것이 좋다.It is preferable that the reinforcing member 600 is positioned so as not to flow by the spot welding method while being in contact with the inner member 110 or the outer member 120.

여기서 상기 내측부재(110)에는 문틀후레임(200)의 요홈부(210)에 설치된 가스켓(230)에 밀착하기 위한 날개부(130)를 일체로 연장한 후 절곡 성형하게 된다.The inner member 110 is integrally formed with a wing 130 for tightly contacting the gasket 230 installed in the recessed portion 210 of the door frame 200 and then bent and formed.

따라서, 이 날개부(130)가 방화문 본체(100)가 닫쳐진 상태에서는 도 4에서와 같이 가스켓(230)에 깊숙이 접촉되면서 문틀후레임(200)과 방화문 본체(100)가 금속으로 연결되는 것을 차단하여 결로방지 효과를 얻을 수 있도록 한다.Therefore, when the wing portion 130 is in the closed state, the wing portion 130 is deeply contacted with the gasket 230 as shown in FIG. 4, and the window frame frame 200 and the fire door main body 100 are prevented from being connected with the metal So that a dew condensation preventing effect can be obtained.

또한, 이 날개부(130)에 의해 실내와 실외를 완전하게 차단시키는 결과로 기밀성과 차음성을 향상시킬 수도 있는 것이다.Further, as a result of the indoor unit and the outdoor unit being completely blocked by the wing 130, airtightness and sound insulation can be improved.

한편, 상기 보강부재(600)는 리벳(500)들을 체결하는 작업을 위해 작업공간부(610)를 절곡 형성하는 것이 바람직 하다.Meanwhile, the reinforcing member 600 may be formed by bending the work space portion 610 in order to fasten the rivets 500.

따라서, 이 작업공간부(610)가 내측으로 절곡 성형되므로, 리벳(500) 체결을 위한 작업이 용이하게 이루어질 수 있는 것은 물론, 보강부재(600)의 단면 계수가 향상되어 변형 강도도 향상시킬 수 있는 것이다.Accordingly, since the work space portion 610 is bent inward, the work for fastening the rivet 500 can be easily performed, and the sectional modulus of the reinforcing member 600 can be improved, It is.

이러한 보강부재(600)는 내측부재(110) 및 외측부재(120)의 두께보다 더 두꺼운 금속재로 전체적으로 대략 M 형상으로 절곡 성형된다.The reinforcing member 600 is formed by bending a metal material having a thickness larger than the thicknesses of the inner member 110 and the outer member 120 to have a generally M shape as a whole.

이때, 이 보강부재(600)에는 수개의 비드홈(620)들을 성형한다.At this time, a plurality of bead grooves 620 are formed in the reinforcing member 600.

이 비드홈(620)들에 의해 보강부재(600)의 변형 강도를 더 크게 향상시킬 수가 있는 것이다.The deformation strength of the reinforcing member 600 can be further improved by the bead grooves 620.

상기 보강부재(600)는 문짝형태의 방화문 둘레를 따라 모두 설치된다.The reinforcing member 600 is installed along the periphery of the door-shaped fire door.
