본 발명은 등간격으로 배열되는 철판의 단부를 상향절곡하고 서로 씨밍(Seaming) 결합하여 지붕조립용으로 사용하는 아치형 판넬의 조립구조에 관한 것으로, 보다 상세하게는 길이가 긴 아치형 판넬을 도로이송이 가능한 길이로 분할하여 공장에서 아치형으로 성형하고 시공현장에서 조인트를 사용하여 일체로 조립하여 시공할 수 있게 한 것에 관한 것이다.The present invention relates to an assembly structure of an arched panel used for assembling a roof by bending up the ends of the iron plates arranged at equal intervals and seaming each other, and more specifically, a long arced panel is transported by road. The present invention relates to an arcuate molding at a factory and to an integral assembly using a joint at a construction site.

일반적으로 넓은 실내공간을 필요로 하는 건축물에서는 가벼우면서도 구조적인 강도가 높고 조립식이어서 시공비를 절감하고 공사기간을 단축할 수 있는 아치형 판넬로 지붕을 시공하는 방법이 공지되어 있다.In general, in a building requiring a large indoor space, a method of constructing a roof with an arched panel, which is light in weight, high in structural strength and prefabricated, can reduce construction cost and shorten construction period.

아치형 판넬은 철판의 가장자리를 절곡성형하고 이웃하는 아치형 판넬과 서로 씨밍 결합하여 연속적으로 이어질 수 있게 구성되며 판넬의 이면에는 그라스울과 같은 난연재로 된 단열흡음재를 부착하고 마감재로 표면을 처리하는 마감공사로 완성된다.The arch panel is formed by bending the edges of the steel plate and seaming with neighboring arch panels so that they can be continuously connected to each other.The panel is attached to the back of the panel by heat-insulating sound absorbing material made of flame retardant materials such as glass wool, and finishing the surface with finishing materials. Is completed.

종래 지붕조립용 아치형 판넬로는 본 출원인이 선출원한바 있는 실용신안등록 제414721호에서는 도 1에 도시한 것과 같이 철판을 상·하부 판넬(102, 103)로 2중으로 형성하되 상·하부 판넬이 중첩되어 형성되는 공간에는 내장재(106)가 삽입되고, 상·하부 판넬의 가장자리 단부는 이웃하는 아치형 판넬의 단부와 씨밍 결합하는 내장재(106)와 일체화된 샌드위치 구조의 아치형 판넬을 제안하여 아치형 판넬의 구조적인 강도를 보강하여 보다 큰 폭의 지붕을 시공할 수 있게 하고 아치형 판넬과 내장재를 일체로 시공할 수 있게 하여 시공비용 및 시간을 줄일 수 있게 한바 있었다.Conventional roof assembly arch type panel in the Utility Model Registration No. 414721, which was filed by the applicant of the present application, as shown in Figure 1 to form a double plate of the upper and lower panels (102, 103), but the upper and lower panels overlap The interior material 106 is inserted into the formed space, and the edge end of the upper and lower panels proposes a sandwich panel-shaped arch panel integrated with the interior material 106 that seams and joins the edges of the neighboring arch panel. By reinforcing the mechanical strength, it was possible to construct a wider roof and to integrate the arched panel and the interior material to reduce the construction cost and time.

그러나 상기와 같은 구성은 지붕을 형성하는 아치형 판넬의 길이가 매우 길고 아치형으로 휘어져 있어 공장에서 성형하여 도로를 통하여 시공현장으로 이송하기가 곤란하므로 성형기계를 시공현장에 설치하여 아치형 판넬을 성형하여야 하는 관계로 도심지와 같이 시공현장에 큰 공간을 확보하기 어려울 경우 시공이 곤란하여, 공간을 확보하여 성형이 가능하더라도 성형기를 설치하고 현장에서 성형작업을 하는 것은 생산성을 저하시켜 시공기간이나 시공비용을 증가시킨다는 문제점이 있었다.However, the above structure is very long and arched panel forming the roof is curved in the arch shape is difficult to transport from the factory to the construction site through the road, so the molding machine must be installed in the construction site to form the arch panel Therefore, when it is difficult to secure a large space in the construction site like the downtown area, it is difficult to install, and even if it is possible to secure the space, installing a molding machine and molding in the field reduces productivity and increases the construction period or construction cost. There was a problem.

본 발명은 상기와 같은 문제점을 해결하기 위하여 개발된 것으로 철판으로 성형절곡되는 아치형 판넬을 도로이송이 가능한 길이로 분할하여 공장에서 성형한 후 시공현장으로 이송하고 조인트를 사용하여 아치형 판넬과 판넬을 서로 결합하여 지붕을 완성하게 하는 수단을 제공하는 것을 목적으로 한다.The present invention was developed in order to solve the above problems, divided by the length of the arc-shaped panel bent to be formed into a steel plate can be transferred to the road after molding in the factory and transported to the construction site using the joint and the arch panel and the panel to each other It is an object to provide a means for joining to complete a roof.

본 발명의 또 다른 목적은 판넬과 판넬을 결합하는 조인트를 이용하여 다양한 형태의 아치형 지붕을 시공할 수 있게 하는 것이다.Still another object of the present invention is to be able to construct various types of arched roof using a panel and a joint combining the panel.

본 발명의 또 다른 목적은 표준화된 규격의 아치형 판넬을 공장에서 안정적으로 생산가능하게 하여 생산성을 향상할 수 있게 하는 것이다.Still another object of the present invention is to make it possible to stably produce arched panels of standardized specifications in a factory, thereby improving productivity.

본 발명의 또 다른 목적은 시공현장이 도심지와 같이 여유공간확보가 어려운 지역에서도 아치형 판넬의 시공을 가능하게 하는 것이다.Another object of the present invention is to enable the construction of the arched panel even in the construction site is difficult to secure the free space, such as downtown.

본 발명의 또 다른 목적은 아치형 판넬의 시공기간과 시공비용을 줄일 수 있게 하는 것이다.Another object of the present invention is to reduce the construction period and the construction cost of the arched panel.

상기한 목적을 위한 본 발명 '아치형 판넬로 형성되는 지붕구조의 결합용 조인트'는 일정한 폭과, 차량으로 운송이 가능한 길이로 절단된 철판을 공장에서 아치형 판넬로 성형한 후, 시공현장에서 조인트를 사용하여 결합하고 크레인으로 들어 올려 지붕을 시공한다.The present invention for the above purpose 'joint for the joint of the roof structure formed of the arch-shaped panel' is a steel plate cut to a certain width, the length that can be transported to the vehicle after forming the arch panel in the factory, the joint at the construction site Use it to join and lift the crane to construct the roof.

조인트는 일정한 길이를 가지고 아치형 판넬의 절곡부를 상·하에서 감싸는 형태로 구성하고 단부는 아치형 판넬과 함께 씨밍 결합되며, 조인트가 결합되는 부분에는 조인트와 아치형 판넬 사이에 누수방지 시트가 삽입되고 조인트와 아치형 판넬의 철판은 피스나 볼트로 체결된다.The joint has a certain length and forms the bent part of the arched panel from above and below. The end is seamed and joined with the arched panel, and the joint where the joint is connected is inserted between the joint and the arched panel. The iron plate of the panel is fastened by a piece or bolt.

또한 조인트는 아치형 판넬과 벽체를 연결하는 부분에도 적용이 가능하다.Joints are also applicable to the part connecting arched panels and walls.
