Description

발포성 합성수지 문틀구조{DOOR FRAME STRUCTURE OF THE PLASTIC DOOR}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a foam structure,

본 고안은 발포성 합성수지 문틀구조에 관한 것으로서, 더욱더 상세하게는 발포성 문틀의 공간에 공압출방식에 의해 필름형태로 혼성중합체가 적층되면서 문틀의 강성이 향상되도록 하는 발포성 합성수지 문틀구조에 관한 것이다.The present invention relates to a foamed synthetic resin door frame structure, and more particularly, to a foamed synthetic resin door frame structure in which a stiffness of a door frame is improved by laminating an interpolymer in a film form by a coextrusion method in a space of the foamable door frame.

일반적으로 널리 사용되고 있는 목재 문틀은 시공과 가공작업이 용이하고 오차발생에 따른 현장가공 작업이 편리한 장점을 갖고 있는 반면, 수분에는 매우 취약하여 쉽게 틀어지게 되는 문제점과 산림훼손에 따른 규제로 인해 원가가 매우 높아 사용에 많은 제약이 따르게 되는 문제점이 있었다.In general, the widely used wood door frame has advantages such as easy construction and machining work and convenience of on-site machining due to errors, but it is very vulnerable to moisture and can be easily twisted. So that there are many restrictions on use.

최근에는 이에 따른 대안으로 합성수지로 제작되는 문틀이 널리 사용되는 추세로써, 이러한 합성수지 문틀(1)은 도 1에 도시된 바와 같이 압출 성형시 재료절감과 중량감소, 그리고 격벽의 내부에 중공부(1a)를 형성하여 강도를 보강하도록 한 것이다.In recent years, door frames made of synthetic resin have been widely used as alternatives. Such synthetic resin door frame 1 has a structure in which materials are reduced and weight is reduced during extrusion molding as shown in FIG. 1, So as to reinforce the strength.

그러나 이와 같은 종래 합성수지 문틀(1)은 소재자체의 특성과, 중공부의 형성 및 문틀의 외곽면이 끊어지지 않고 서로 이어지는 구조에 의해 경화시 중공부 내측의 온도와 문틀 외부의 온도가 차이가 있어 서로 다른 수축율이 초래되고, 이에 따라 문틀 전체가 틀어지거나 면이 고르지 않고 울퉁불퉁해지는 문제점이 있었으며, 압출 및 인발공정을 거친 후 커팅할 때 크랙이 발생되는 문제점이 있었다.However, due to the characteristics of the material itself and the structure in which the hollow portion is formed and the outer surface of the door frame is not broken, the temperature of the inside of the hollow portion differs from the temperature of the outside of the door frame during curing, There is a problem in that the entire door frame is twisted, the surface becomes uneven and uneven, and there is a problem that a crack is generated in the cutting after the extrusion and drawing process.

또한, 중공부(1a)를 갖는 종래의 문틀(1)은 시공되는 면이 평활하여 벽체 모르타르와의 결합력이 매우 낮고, 목재 문틀의 결합시에 못을 박는다 하더라도 그 못을 지지하는 실질적인 단부 면적이 적어 견고한 체결효과를 기대하기 어려웠고, 설치 후 사용시에도 중공부로 인해 문짝의 여닫음 작동 중에 소음이 크게 발생되는 문제점이 있었다.In addition, the conventional door frame 1 having the hollow portion 1a has a very low bonding force with the wall mortar because the surface to be applied is smooth, and even if the nail is stuck when joining the wooden door frames, It is difficult to expect a strong fastening effect and there is a problem that noise is largely generated during the operation of closing the door due to the hollow portion even after use.

이러한 문제점을 해결하기 위해 하기 특허문헌인 국내 등록실용신안 제129028호에는 도 2와 도 3에 도시하고 있는 바와 같이, 합성수지 문틀을 형성함에 있어서, 상면 일측에 문틀에 설치된 문짝이 닫히어 걸릴 수 있게 하는 단턱(10a)을 가지며, 또 다른 일측면에는 문틀이 설치되는 건물의 바닥면과의 높이차이를 적게하여 출입시에 불편을 전가하지 않게 하는 경사면(10b)을 이루며, 발포성 합성수지재로 된 문틀(10)의 저면에 다단으로 이루어지는 공간(11)을 형성하고, 상기 공간(11)의 외벽에 문틀(10)의 휨을 방지하는 보강재(20)를 설치하는 발포성 합성수지 문틀구조가 개시되어있다.In order to solve such a problem, as shown in FIG. 2 and FIG. 3, the Korean Registered Utility Model No. 129028, which is a patent document, discloses a method for forming a synthetic resin door frame in which a door provided on a door frame is closed (10a), and the other side of the door frame (10) has a sloped surface (10b) which reduces the difference in height between the floor surface and the bottom surface of the building on which the door frame is installed, And a stiffener 20 for preventing the door frame 10 from being warped is formed on the outer wall of the space 11 by forming a multi-stage space 11 on the bottom surface of the door frame 10.

그러나 이 역시도 문틀(10)을 제작 시 공간(11)이 하부에 형성된 문틀과, 상기 문틀(10)의 공간(11)에 삽입되면서 나사(30)와 같은 체결구로 고정이 이루어지는 보강재(20)를 각각 제작하여야 함으로써, 상기 문틀(10)의 제작시 보강재(20)를 제작하기 위한 별도의 작업공간이 필요하게 됨은 물론, 상기 문틀(10)과 보강재(20)를 결합시키기 위한 별도의 결합작업을 수행해야 함으로써, 상기 문틀(10)이 휨이나 뒤틀림이 발생하지 않도록 하기 위하여 제조단가가 상승되는 문제점이 있었다.However, it is also possible to use a door frame formed with the space 11 at the bottom and a reinforcing member 20 to be fixed to the space 11 of the door frame 10 by a fastener such as a screw 30 when the door frame 10 is manufactured A separate work space for manufacturing the stiffener 20 is required at the time of manufacturing the door frame 10 and a separate joining operation for joining the door frame 10 and the stiffener 20 is required The manufacturing cost of the door frame 10 is increased in order to prevent the door frame 10 from being warped or distorted.

또한, 종래에는 문틀(10)의 길이와 동일한 길이로 보강재(20)를 재단시킨 상태에서 공간(11)에 설치시, 상기 보강재(20)가 문틀(10)의 길이와 상이한 길이로 재단된 경우에는 문틀(10)의 시공이 어렵게 되는 등의 문제점이 있었다.
When the stiffener 20 is cut to have a length different from the length of the door frame 10 when the stiffener 20 is cut in the same length as that of the door frame 10 and is installed in the space 11 The construction of the door frame 10 becomes difficult.

본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서, 문틀의 이면에 형성되어있는 공간에 혼합중성체를 필름형태로 일체로 적층시켜 주는 것에 의해 문틀의 강성이 향상되도록 함으로써, 상기 문틀을 제작시 강성이 향상되도록 하는 별도의 보강판을 제작하기 위한 작업공간을 필요로 하지 않도록 하여 작업공간이 축소되도록 함과 동시에 상기 보강판을 공간부에 설치하는 별도의 결합작업을 수행하지 않아도 되어 문틀의 제작비용이 절감되어질 수 있도록 하는 발포성 합성수지 문틀구조를 제공하는 데 있다.The object of the present invention is to solve the above-mentioned problems of the prior art. The object of the present invention is to improve the rigidity of the door frame by integrally laminating the mixed substances in the form of film in the space formed on the back surface of the door frame, The work space is reduced by not requiring a work space for manufacturing a separate reinforcing plate for improving the rigidity when the door frame is manufactured, and a separate joining operation for installing the reinforcing plate in the space portion is performed So that the manufacturing cost of the door frame can be reduced.

표면에는 단턱(110)과 경사면(120)이 형성되고, 이면에는 구획벽(130)에 의해 구획되는 공간(140)이 각각 형성되는 발포성 합성수지 문틀(100)에 있어서, 상기 문틀(100)의 이면에 형성된 공간(140)에 공압출방식에 의해 강성이 향상되도록 필름형태로 혼합중성체(200)가 적층되는 것에 의해 달성된다.A foam synthetic resin door frame (100) having a step (110) and an inclined surface (120) formed on a surface thereof and a space (140) defined by a partition wall (130) Is formed by stacking the mixed medium 200 in the form of a film so that rigidity is improved by a co-extrusion method.

한편, 상기 혼합중성체(200)는 열에 대한 안정한 성질이 있는 스타이렌과 불포화나이트릴인 아크릴로나이트릴을 중합시켜 만들어진 물질이다.On the other hand, the mixed medium 200 is a material produced by polymerizing styrene having stable properties against heat and acrylonitrile as an unsaturated nitrile.

또한, 상기 공압출방식에 의해 필름형태로 적층되는 혼합중성체(200)가 다이내접착법 또는 다이외접착법 중 어느 하나의 방법으로 적층되어지게 됨을 밝혀 둔다.  Further, it is revealed that the mixed medium 200 to be laminated in the form of a film by the co-extrusion method is laminated by any one of the dummy bonding method and the non-bonding method.

본 고안에 따르면 구획벽에 의해 구획되면서 문틀의 이면에 형성된 공간에 강성이 향상되도록 혼성중성체가 일체로 적층 되어있어, 상기 문틀의 강성이 향상되도록 하는 별도의 보강판을 설치하지 않아도 되어 문틀을 제작시 제작비용이 절감되어지게 됨은 물론, 상기 문틀을 시공시에도 별도의 보강재를 문틀의 길이에 맞추어 재단한 후 공간에 결합시키지 않아도 됨으로써, 시공성이 향상되어 지게 되는 등의 효과가 있는 매우 유용한 고안이다.According to the present invention, there is no need to provide a separate reinforcement plate for reinforcing the rigidity of the door frame because the composite hollow bodies are integrally laminated so as to improve rigidity in the space formed on the rear face of the door frame while being partitioned by the partition walls. It is possible to reduce the manufacturing cost in the manufacturing process and to prevent the reinforcing member from being cut in accordance with the length of the door frame even when the door frame is installed, to be.

이하 첨부된 도면에 의하여 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical structure of the present invention will be described in detail with reference to the accompanying drawings.

도 4는 본 고안의 발포성 합성수지 문틀구조를 보인 단면도 이고, 도 5는 본 고안의 발포성 합성수지 문틀구조를 보인 저면사시도 이며, 도 6은 본 고안인 발포성 합성수지 문틀구조의 실시예를 보인 단면도이다.FIG. 4 is a cross-sectional view showing the foamed synthetic resin door frame structure of the present invention, FIG. 5 is a bottom perspective view showing the foamed synthetic resin door frame structure of the present invention, and FIG. 6 is a sectional view showing an embodiment of the foamed synthetic resin door frame structure of the present invention.

본 고안의 발포성 합성수지 문틀구조도 도 4와 도 5 및 도 6에 도시하고 있는 바와 같이, 표면 일측부에 문틀(100)에 설치된 문짝이 닫히어 걸릴 수 있게 하는 단턱(110)이 형성되고, 상기 단턱(110)이 형성된 표면 타측부에는 문틀(100)이 설치되는 건물의 바닥면과의 높이차이를 적게하여 출입시에 불편함을 느끼지 않도록 하는 경사면(120)이 형성되며, 상기 문틀(100)의 이면에는 양측벽(150)과 구획벽(130) 사이에 공간(140)이 형성되는 것에 있어서, 상기 문틀(100)의 이면에 형성된 공간(140)에 공압출방식에 의해 강성이 향상되도록 필름형태로 혼합중성체(200)가 적층된다. As shown in FIGS. 4, 5, and 6, a step 110 is formed on one side of the front surface so as to allow the door provided on the door 100 to be closed and hooked, The inclined surface 120 is formed on the side of the surface on which the step 110 is formed so as to reduce the difference in height between the bottom surface of the building where the door 100 is installed and the inconvenience at the time of entrance and exit, A space 140 is formed between the side walls 150 and the partition wall 130 on the rear surface of the door frame 100. The space 140 formed in the back surface of the door frame 100 is formed with a film The mixed body 200 is stacked.

이때, 상기 혼합중성체(200)는 열에 대한 안정한 성질이 있는 스타이렌과 불포화나이트릴인 아크릴로나이트릴을 중합시켜 만들어진 물질이다.At this time, the mixed medium 200 is a material produced by polymerizing styrene having stable properties against heat and acrylonitrile as an unsaturated nitrile.

한편, 상기 공압출방식에 의해 필름형태로 적층되는 혼합중성체(200)가 다이내접착법 또는 다이외접착법 중 어느 하나의 방법으로 적층되어, 상기 혼합중성체(200)가 문틀로 부터 분리되지 않도록 한다.  On the other hand, the mixed inert materials 200 laminated in the form of a film by the co-extrusion method are laminated by any one of the dummy bonding method and the non-bonding method, and the mixed medium 200 is separated from the door frame .

또한, 상기 문틀(100)은 PVC, ABS, PP, PE등의 발포성 합성수지로 이루어지는 것으로써, 이러한 문틀(100)의 표면에는 문의 개방을 한정하기 위한 일종의 스톱퍼 역활을 하는 단턱(110)이 형성됨과 동시에 건물의 바닥면과의 높이차를 작게하여 출입시에 발에 걸리지 않도록 완만한 경사면이 형성되며, 상기 문틀(100)의 이면에는 양측벽(150)과 구획벽(130) 사이로 공간(140)이 각각 형성된다.The door frame 100 is made of foamed synthetic resin such as PVC, ABS, PP, PE, etc., and a step 110 serving as a kind of stopper for defining the door opening is formed on the surface of the door frame 100 A gap 140 is formed between the side walls 150 and the partition walls 130 on the rear surface of the door frame 100 so that the space 140 is formed between the side walls 150 and the partition walls 130, Respectively.

이와 같이 구성되는 본 고안에 따르면 문틀(100)의 이면에 형성된 공간(140)과 상기 공간(140)을 형성하고 있는 구획벽(130)에 적층되게 열에 대한 안정한 성질이 있는 스타이렌과 불포화나이트릴인 아크릴로나이트릴을 중합시켜 만들어진 혼합중성체(200)가 공압출방식에 의해 강성이 향상되도록 필름형태로 일체로 적층되어지기 때문에 종래와 같이 별도의 보강판을 제작하여 나사와 같은 체결도구를 이용해 결합시키는 것에 의해 문틀의 강성이 향상되도록 하는 작업을 수행하지 않아도 된다. According to the present invention configured as described above, the space 140 formed on the back surface of the door frame 100 and the partition wall 130 forming the space 140 are stacked, and styrene and an unsaturated nitrile Since the mixed bodies 200 made by polymerizing the acrylonitrile are integrally laminated in a film form so as to improve the rigidity by the coextrusion method, a separate reinforcing plate is manufactured as in the prior art, It is not necessary to perform an operation for improving the rigidity of the door frame.

한편, 상기 문틀(100)에 혼합중성체(200)가 강성이 향상되도록 구획벽(130) 및 공간(140)에 일체로 적층되어 있어, 문틀(100)을 건축물에 시공하기 위해 필요한 길이로 절단시, 상기 혼합중성체(200)도 문틀과 동일한 길이로 절단되므로서, 상기 문틀(100)을 강성이 향상된 상태로 제작한 후 필요한 길이로 재단하여 사용하는 것이 용이하게 되어, 건축물에 문틀(100)을 시공하는 작업을 수행시 작업성이 향상되어 지게 된다.
The mixed body 200 is integrally laminated in the partition wall 130 and the space 140 so as to improve rigidity in the door frame 100 so that the door frame 100 is cut to a length necessary for constructing the door frame 100 The mixed body 200 is cut to have the same length as that of the door frame so that the door frame 100 can be manufactured in a state of improved rigidity and cut to a required length and used easily, The workability of the work is improved.
