Description

긴장장치를 구비하는 철골지붕시스템{STEEL ROOF SYSTEM HAVING TENSIONING APPARATUS}Steel frame roof system with tension device {STEEL ROOF SYSTEM HAVING TENSIONING APPARATUS}

본 발명은 철골지붕시스템에 관한 것으로, 보다 상세하게는 라멘 형식으로 구성되는 철골구조물에서의 긴장장치를 구비하는 철골지붕시스템에 관한 것이다.The present invention relates to a steel roof system, and more particularly, to a steel roof system having a tension device in the steel structure is configured in the ramen form.

최근에는 건물의 대형화 추세에 따라 철골구조물의 기둥과 기둥 사이의 간격이 멀어지게 배치되도록 철골구조물을 구성한다. 그런데, 이와 같이 철골구조물의 기둥과 기둥 사이의 간격이 멀어지게 배치되는 장경간화에 따라 기둥에 의해 지지되지 않는 영역에서의 보의 처짐 현상을 방지할 필요가 있다.In recent years, steel structures are constructed so that the space between the pillars and the pillars of the steel structure is arranged far from each other in accordance with the trend of large-scale building. However, it is necessary to prevent the deflection of the beam in the region not supported by the column according to the long span in which the distance between the pillar and the pillar of the steel structure is far apart.

즉, 철골구조물에서의 붕괴는 하중에 대한 과도한 처짐 발생에 따라 골조, 즉 보와 기둥의 치우침 현상이 붕괴 원인의 하나로 지적되고 있고, 따라서, 보의 처짐 현상이 방지되어야 한다.In other words, the collapse of the steel structure is pointed out as one of the causes of the collapse of the frame, that is, the beam and column as the excessive deflection of the load, and therefore, the deflection of the beam should be prevented.

이를 위해, 지붕을 구성하는 부재로 단면의 춤을 크게 하여 과도한 처짐을 방지하고, 모멘트 분포에 따라 단면의 크기를 결정함으로써 경제성을 가지는 변단면부재가 사용되고 있다.To this end, a cross sectional member having economical efficiency is used by increasing the cross section as a member constituting the roof to prevent excessive sag and determining the size of the cross section according to the moment distribution.

그런데, 이러한 변단면 부재는 별도의 부재 제작 과정을 거쳐야 하므로, 건 축원가 상승의 원인이 되는 문제가 있으며, 자재공급이 원활하지 못해 시공기간을 늘어나게 하는 문제가 있다.By the way, such a cross-section member has to go through a separate member manufacturing process, there is a problem that causes a rise in construction costs, there is a problem to increase the construction period due to the smooth supply of materials.

더하여, 박공형 지붕을 채용하는 철골구조물에 사용되는 지붕재, 즉 변단면 부재는 상당한 춤을 갖도록 형성되며, 이에 따라 변단면 부재의 좌굴에 대한 안정성에 문제가 있다.In addition, the roofing material, ie, the cross-sectional member, used in the steel frame structure employing the gable roof is formed to have a significant dance, and thus there is a problem in the stability to the buckling of the cross-sectional member.

한편, 기존의 창고나 공장 등의 단층형 철골구조물에서 지붕에는 적재물이 상부에 장착되지 않으므로, 변단면 부재만으로도 지붕의 처짐을 방지할 수 있었다. 그러나, 최근에는 친환경 건축으로 인하여 태양열 패널 등이 지붕에 설치되므로, 지붕의 처짐 발생을 방지할 수 있는 방안이 더욱 절실하게 필요한 실정이다.On the other hand, in the conventional single-layered steel structure, such as warehouses and factories, since the load is not mounted on the roof, the deflection of the roof can be prevented with only the end face member. However, recently, since solar panels are installed on the roof due to environmentally friendly construction, there is an urgent need for a method that can prevent sagging of the roof.

본 발명은 지붕을 구성하는 구조물의 구조적 안정성을 향상시킬 수 있는 긴장장치를 구비하는 철골지붕시스템을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a steel roof system having a tension device that can improve the structural stability of the structure constituting the roof.

본 발명에 따른 긴장장치를 구비하는 철골지붕시스템은 일단부가 기둥에 접합되고, 타단부가 서로 연결되어 지붕의 골조를 형성하는 한쌍의 골조부재, 및 상기 골조부재에 장착되며 긴장재에 의한 압축력을 통해 상기 골조부재의 타단부에 가해지는 수직하중을 감쇠시키는 긴장장치를 포함한다.Steel frame roof system having a tension device according to the invention is a pair of frame members, one end is joined to the pillar, the other end is connected to each other to form a frame of the roof, and is mounted on the frame member through the compressive force by the tension material And a tensioning device for damping the vertical load applied to the other end of the frame member.

상기 긴장장치는 PS 강선 또는 PS 강봉으로 이루어지는 상기 긴장재, 및 접합되는 상기 골조부재 각각에 고정설치되며, 상기 긴장재의 양단부가 장착되는 정착유닛을 구비할 수 있다.The tension device may be provided with a fixing unit which is fixed to each of the tension member made of a PS steel wire or a PS steel rod, and the frame member to be joined, both ends of the tension member.

상기 긴장장치는 상기 긴장재의 양단부가 장착되는 상기 정착유닛의 사이에 배치되며, 상기 긴장재의 중앙부를 정착시키는 안전유닛을 더 구비할 수 있다.The tension device may be further disposed between the fixing unit to which both ends of the tension member are mounted, and may further include a safety unit to fix the central portion of the tension member.

상기 정착유닛은 상기 골조부재에 접합되고 상기 긴장재가 관통하는 지지부재, 및 상기 지지부재에 구비되는 설치부에 삽입되어 상기 긴장재를 고정시키는 정착부재를 구비할 수 있다.The fixing unit may include a support member joined to the frame member and penetrating the tension member, and a fixing member inserted into an installation part provided in the support member to fix the tension member.

상기 정착유닛은 상기 지지부재에 구비되며 상기 긴장재로부터 상기 지지부 재로 전달되는 압축력에 의한 상기 지지부재의 파손을 방지하는 보강부재를 더 구비할 수 있다.The fixing unit may further include a reinforcing member provided in the support member to prevent breakage of the support member due to a compressive force transmitted from the tension member to the support member.

상기 안전유닛은 양측면이 각각의 상기 골조부재의 끝단부와 접합되는 접합부재의 적어도 일면에 구비되는 설치부재와, 상기 설치부재에 삽입 결합되어 긴장재의 중앙부를 정착시키는 고정부재를 구비할 수 있다.The safety unit may include an installation member provided on at least one surface of the joining member, the both sides of which are joined to the end of each frame member, and a fixing member inserted into the installation member to fix the central portion of the tension member.

상기 골조부재는 H 형강보로 이루어질 수 있다.The frame member may be made of H-beams.

본 발명에 따르면, 골조부재에 압축력을 제공하는 긴장장치를 통하여 골조부재의 상부측으로 작용되는 하중을 제공함으로써, 골조부재의 처짐을 감소시킬 수 있어 골조부재의 자체 하중과 지붕의 상부에 설치되는 구조물에 의한 하중에 대한 구조물의 구조적 안정성을 향상시킬 수 있는 효과가 있다.According to the present invention, by providing a load acting on the upper side of the skeleton member through the tension device for providing a compressive force to the skeleton member, it is possible to reduce the deflection of the skeleton member structure to be installed on the self load of the skeleton member and the top of the roof There is an effect that can improve the structural stability of the structure against the load by.

이에 따라, 골조부재가 H 형강보로 이루질 수 있으므로, 시공원가와 시공기간을 단축시킬 수 있다.Accordingly, the frame member can be made of H-beams, it is possible to shorten the construction time and the city park.

더하여, 긴장재의 일영역이 파손되더라도 파손되지 않은 긴장재를 고정시키는 정착유닛과 안전유닛을 통해 긴장재로부터 압축력을 계속해서 제공할 수 있으므로, 긴장재 파손을 대비할 수 있는 효과가 있다.In addition, even if one region of the tension member is damaged, it is possible to continuously provide the compressive force from the tension member through the fixing unit and the safety unit for fixing the undamaged tension member, thereby preparing for the tension member damage.

그리고, 긴장장치에 배치되는 접합부재의 하단부측에는 긴장장치에 의해 골조부재가 접합될 수 있으므로, 접합을 위한 볼트체결 또는 용접을 생략할 수 있으므로 시공성이 향상되는 효과가 있다.And, since the frame member can be joined to the lower end side of the joining member disposed in the tensioning device by the tensioning device, there is an effect that the workability is improved because the bolt fastening or welding for the joining can be omitted.

이하에서는 도면을 참조하여 본 발명의 일실시예에 따른 긴장장치를 구비하는 철골지붕시스템에 대하여 설명하기로 한다.Hereinafter, with reference to the drawings will be described for the steel roof system having a tension device according to an embodiment of the present invention.

도 1은 본 발명의 일실시예에 따른 긴장장치를 구비하는 철골지붕시스템을 나타내는 구성도이다.1 is a block diagram showing a steel roof system having a tension device according to an embodiment of the present invention.

도 1을 참조하면, 긴장장치를 구비하는 철골지붕시스템(100, 이하 '철골지붕시스템'이라 함)은 일예로서, 골조부재(120), 긴장장치(130), 및 접합부재(140)를 포함한다.Referring to FIG. 1, the steel frame roof system (100, hereinafter referred to as “steel frame roof system”) having a tension device includes a frame member 120, a tension device 130, and a bonding member 140. do.

골조부재(120)는 한쌍으로 이루어지며, 일단부가 기둥(10)에 접합되고 타단부가 서로 연결되어 지붕의 골조를 형성한다. 한편, 골조부재(120)는 일예로서 H 형강보일 수 있다.Frame member 120 is composed of a pair, one end is joined to the column 10 and the other end is connected to each other to form a frame of the roof. On the other hand, the frame member 120 may be an H-beam steel beam as an example.

한편, 골조부재(120)가 H 형강보로 이루어진 경우, 골조부재(120)는 상부 플랜지(122), 웨브(124), 및 하부 플랜지(124)로 구성된다.On the other hand, when the frame member 120 is made of H-beam, the frame member 120 is composed of an upper flange 122, a web 124, and a lower flange 124.

기둥(10)의 끝단부는 골조부재(120)와의 접합을 위해 경사지게 형성될 수 있으며, 끝단에는 엔드플레이트(12)가 구비될 수 있다. 골조부재(120)의 일단부는 상기한 엔드플레이트(12)에 접합되어 기둥(10)에 접합될 수 있다.The end of the pillar 10 may be formed to be inclined for bonding to the frame member 120, the end may be provided with an end plate 12. One end of the frame member 120 may be bonded to the end plate 12 to be connected to the pillar 10.

다만, 이에 한정되지 않으며 골조부재(120)는 직접 기둥(10)에 접합될 수 있다.However, the present invention is not limited thereto, and the frame member 120 may be directly connected to the pillar 10.

상기한 바와 같이, 골조부재(120)의 끝단부가 경사지게 형성된 기둥(10)에 접합되므로, 골조부재(120)는 경사지게 배치되어 지붕의 골조를 형성한다.As described above, since the end portion of the frame member 120 is bonded to the pillar 10 formed to be inclined, the frame member 120 is disposed to be inclined to form a frame of the roof.

이와 같이, 양측에 배치되는 기둥(10)에 한쌍의 골조부재(120)의 일단부가 접합되면, 골조부재(120)의 타단부는 기둥(10)과 기둥(10) 사이에서 연결된다.As such, when one end of the pair of frame members 120 is joined to the pillars 10 disposed on both sides, the other end of the frame member 120 is connected between the pillar 10 and the pillar 10.

이때, 골조부재(120)와 골조부재(120)의 타단부 사이에는 접합부재(140)가 배치된다. 즉, 골조부재(120)의 타단부는 접합부재(140)의 양측면에 접합되어 고정된다.At this time, the bonding member 140 is disposed between the skeleton member 120 and the other end of the skeleton member 120. That is, the other end of the skeleton member 120 is bonded to both sides of the bonding member 140 is fixed.

긴장장치(130)는 골조부재(120)에 장착되며, 긴장재에 의한 압축력을 통해 골조부재(120)의 타단부에 가해지는 수직하중을 감쇠시킨다.The tension device 130 is mounted to the frame member 120, and attenuates the vertical load applied to the other end of the frame member 120 through the compressive force by the tension member.

한편, 긴장장치(130)는 긴장재(150), 정착유닛(160), 및 안전유닛(170)을 구비할 수 있다.Meanwhile, the tension device 130 may include a tension member 150, a fixing unit 160, and a safety unit 170.

긴장재(150)는 PS 강선 또는 PS 강봉으로 이루어질 수 있으며, 인장잭(미도시)에 의해 인장된다. 이후, 인장잭이 제거되면 긴장재(150)는 압축력을 발생한다. 즉, 긴장재(150)는 원래의 형상으로 복원하려는 압축력을 발생시켜 종국적으로 골조부재(120)의 타단부에 가해지는 수직하중을 감쇠시킨다.The tension member 150 may be made of a PS steel wire or a PS steel rod, and is tensioned by a tension jack (not shown). Then, when the tension jack is removed, the tension member 150 generates a compressive force. That is, the tension member 150 attenuates the vertical load applied to the other end of the frame member 120 by generating a compressive force to restore the original shape.

한편, PS 강선과 PS 강봉은 긴장장치(130)에 일반적으로 채용되는 구성으로서, 당업계에서 널리 알려진 구성에 해당하므로 자세한 설명은 생략하기로 한다.On the other hand, PS steel wire and PS steel bar is a configuration that is generally employed in the tension device 130, because it corresponds to a configuration well known in the art will be omitted a detailed description.

정착유닛(160)은 한쌍의 골조부재(120)의 각각에 고정 설치되며, 긴장재(150)의 양단부를 정착시킨다.The fixing unit 160 is fixedly installed on each of the pair of frame members 120 and fixes both ends of the tension member 150.

정착유닛(160)에 대해서는 도 2 및 도 3을 참조하여 보다 자세하게 설명하기로 한다.The fixing unit 160 will be described in more detail with reference to FIGS. 2 and 3.

도 2 및 도 3을 참조하면, 정착유닛(160)은 지지부재(162), 보강부재(164), 및 정착부재(166)를 구비할 수 있다.2 and 3, the fixing unit 160 may include a supporting member 162, a reinforcing member 164, and a fixing member 166.

지지부재(162)는 골조부재(120)에 접합되고 긴장재(150)가 관통된다. 즉, 지지부재(162)는 골조부재(120)의 웨브(124) 측면에 고정설치되고, 긴장재(150)가 관통되도록 장착될 수 있다.The support member 162 is bonded to the frame member 120 and the tension member 150 is penetrated. That is, the support member 162 may be fixed to the side of the web 124 of the frame member 120, and may be mounted to penetrate the tension member 150.

한편, 지지부재(162)에는 정착부재(166)가 장착되는 설치부(162a)가 구비될 수 있다. 즉, 정착부재(166)는 설치부(162a)에 삽입 장착되어 설치부(162a)를 관통하는 긴장재(150)를 고정 정착시킬 수 있다.On the other hand, the support member 162 may be provided with an installation portion 162a on which the fixing member 166 is mounted. That is, the fixing member 166 may be fixedly fixed to the tension member 150 inserted into the installation unit 162a and penetrating the installation unit 162a.

보강부재(164)는 지지부재(162)에 구비되며, 상기 긴장재(150)에 의해 상기 지지부재(162)로 전달되는 압축력에 의한 지지부재(162)의 파손을 방지한다. 이를 위해 보강부재(164)는 어느 일측면이 지지부재(162)에 접합되고, 상기한 일측면과 접하는 측면은 골조부재(120)의 웨브(124)에 접합된다. 다시 말해, 보강부재(164)의 두측면은 지지부재(162)와 웨브(124)에 각각 접합된다.The reinforcing member 164 is provided in the support member 162 and prevents the support member 162 from being damaged by the compressive force transmitted to the support member 162 by the tension member 150. To this end, one side of the reinforcing member 164 is bonded to the support member 162, the side in contact with the one side is bonded to the web 124 of the skeleton member 120. In other words, two side surfaces of the reinforcing member 164 are bonded to the support member 162 and the web 124, respectively.

한편, 보강부재(164)는 강도보강을 위한 리브와 같은 역할을 수행하며, 이에 따라 지지부재(162)에 압축력이 전달되더라도 지지부재(162)가 파손되는 것을 방지할 수 있다.On the other hand, the reinforcing member 164 serves as a rib for strength reinforcement, thereby preventing the support member 162 from being damaged even if a compressive force is transmitted to the support member 162.

다만, 도면에는 보강부재(164)가 플레이트 형상으로 형성되는 경우를 예로 들어 도시하고 있으나 이에 한정되지 않으며, 보강부재(164)의 개수 또한 다양하게 변경 가능할 것이다.However, the drawing shows a case in which the reinforcing member 164 is formed in a plate shape as an example, but is not limited thereto. The number of the reinforcing members 164 may also be variously changed.

정착부재(166)는 지지부재(162)에 구비되는 설치부(162a)에 삽입되어 긴장재(150)를 정착시킨다. 즉, 정착부재(166)는 고정쐐기와 같은 역할을 수행하며, 긴장재(150)가 인장잭에 의해 인장된 후 정착부재(166)는 설치부(162a)에 삽입 장착 되어 긴장재(150)를 정착시킨다.The fixing member 166 is inserted into the installation part 162a provided in the supporting member 162 to fix the tension member 150. That is, the fixing member 166 serves as a fixing wedge, and after the tension member 150 is tensioned by the tension jack, the fixing member 166 is inserted into the installation portion 162a to fix the tension member 150. Let's do it.

한편, 도 2에 도시된 바와 같이, 정착부재(166)는 일예로서 4개의 블럭이 연계하여 긴장재(150)를 파지하도록 구성될 수 있다. 즉, 4개의 블럭이 설치부(162a)에 삽입되면 긴장재(150)는 4개의 블럭으로 구성된 정착부재(166)에 의해 변형되면서 정착되는 것이다.On the other hand, as shown in Figure 2, the fixing member 166 may be configured to hold the tension member 150 in association with four blocks as an example. That is, when four blocks are inserted into the installation portion 162a, the tension member 150 is fixed while being deformed by the fixing member 166 composed of four blocks.

또한, 정착부재(166)는 지지부재(162)를 관통하지 못하도록 상부측이 절단된 사각뿔 형상을 가지도록 형성될 수 있다. 즉, 긴장재(150)로부터 전달된 압축력에 의해 정착부재(166)가 지지부재(162)를 관통하지 못하도록 정착부재(166)의 일측의 단면이 타측의 단면보다 작은 면적을 가지도록 형성될 수 있다.In addition, the fixing member 166 may be formed to have a square pyramid shape, the upper side of which is not cut through the supporting member 162. That is, the cross section of one side of the fixing member 166 may have a smaller area than the cross section of the other side so that the fixing member 166 does not penetrate the support member 162 by the compressive force transmitted from the tension member 150. .

한편, 정착부재(166)는 억지끼움 방식으로 설치부(162a)에 삽입 장착될 수 있다.On the other hand, the fixing member 166 may be inserted into the installation portion 162a in a interference fit manner.

이와 같이, 긴장재(150)의 양단부가 정착유닛(160)에 의해 정착되면, 긴장재(150)로부터 발생되는 압축력은 먼저 정착부재(166)로 전달된다. 정착부재(166)에 전달된 압축력은 이후 지지부재(162)에 전달되고, 이에 따라 지지부재(162)가 장착되는 골조부재(120)에 압축력이 전달된다.As such, when both ends of the tension member 150 are fixed by the fixing unit 160, the compressive force generated from the tension member 150 is first transmitted to the fixing member 166. The compressive force transmitted to the fixing member 166 is then transmitted to the support member 162, and thus the compressive force is transmitted to the frame member 120 on which the support member 162 is mounted.

따라서, 도 1에 도시된 바와 같이, 골조부재(120)의 접합부, 즉 골조부재(120)의 타단부측으로 압축력이 전달되어 골조부재(120)의 타단부에 가해지는 수직하중을 감쇠시킬 수 있다.Therefore, as shown in FIG. 1, the compressive force is transmitted to the joint portion of the frame member 120, that is, the other end side of the frame member 120, thereby attenuating the vertical load applied to the other end of the frame member 120. .

한편, 도 1에 도시된 바와 같이, 안전유닛(170)은 긴장재(150)의 양단부가 장착되는 정착유닛(160)의 사이에 배치되며 긴장재(150)를 정착시킨다.On the other hand, as shown in Figure 1, the safety unit 170 is disposed between the fixing unit 160 is mounted on both ends of the tension member 150 to fix the tension member 150.

안전유닛(170)에 대해서는 도 4 및 도 5를 참조하여 보다 자세하게 설명하도록 한다.The safety unit 170 will be described in more detail with reference to FIGS. 4 and 5.

도 4 및 도 5를 참조하면, 안전유닛(170)은 접합부재(140)의 적어도 일면에 구비되는 설치부재(172)와, 설치부재(172)에 삽입 결합되어 긴장재(150)를 정착시키는 고정부재(174)를 구비할 수 있다.4 and 5, the safety unit 170 is fixed to fix the tension member 150 by being coupled to the installation member 172 and the installation member 172 provided on at least one surface of the bonding member 140. The member 174 may be provided.

한편, 설치부재(172)는 접합부재(140)의 양측면에 구비되는 장착부(142)에 고정 접합된다. 장착부(142)는 도 5에 도시된 바와 같이, 사다리꼴 형상의 단면을 가지도록 형성될 수 있다. 이에 따라, 장착부(142)에 장착되는 설치부재(172)도 장착부(142)의 형상에 대응되는 형상으로 형성될 수 있다.On the other hand, the installation member 172 is fixedly bonded to the mounting portion 142 provided on both sides of the bonding member 140. The mounting portion 142 may be formed to have a trapezoidal cross section, as shown in FIG. 5. Accordingly, the installation member 172 mounted on the mounting portion 142 may also be formed in a shape corresponding to the shape of the mounting portion 142.

다만, 장착부(142)와 설치부재(172)의 단면 형상은 상기한 형상으로 한정되지 않으며, 긴장재(150)로부터 전달되는 압축력에 의해 고정부재(174)가 설치부재(172)에 고정 장착될 수 있는 어떠한 형상도 채용 가능할 것이다. 예를 들어, 장착부(142)와 설치부재(172)의 단면의 형상은 직사각형 형상으로 형성될 수도 있을 것이다.However, the cross-sectional shape of the mounting portion 142 and the installation member 172 is not limited to the above-described shape, the fixing member 174 may be fixedly mounted to the installation member 172 by the compressive force transmitted from the tension member 150. Any shape may be employed. For example, the shape of the cross section of the mounting portion 142 and the installation member 172 may be formed in a rectangular shape.

고정부재(174)는 접합부재(140)를 관통하는 긴장재(150)를 정착시킨다. 즉, 긴장재(150)는 접합부재(140)의 관통홀(144)을 관통하도록 배치되며, 접합부재(140)의 양측면에서 고정부재(174)에 의해 정착된다.The fixing member 174 fixes the tension member 150 penetrating the bonding member 140. That is, the tension member 150 is disposed to pass through the through hole 144 of the bonding member 140, and is fixed by the fixing member 174 on both sides of the bonding member 140.

고정부재(174)도 정착부재(166)와 같이 고정쐐기와 같은 역할을 수행하며, 긴장재(150)가 인장잭에 의해 인장된 후 고정부재(174)가 설치부재(172)에 삽입 장착되면 긴장재(150)는 고정부재(174)에 의해 정착된다.The fixing member 174 also serves as a fixing wedge like the fixing member 166. When the fixing member 174 is inserted into the installation member 172 after the tension member 150 is tensioned by the tension jack, the tension member 150 is fixed by the fixing member 174.

한편, 도 4에 도시된 바와 같이, 고정부재(174)도 4개의 블럭이 연계하여 긴장재(150)를 파지하도록 구성될 수 있다. 즉, 4개의 블럭이 설치부재(172)에 삽입되면 긴장재(150)는 4개의 블럭으로 구성된 고정부재(174)에 의해 변형되면서 정착되는 것이다.Meanwhile, as shown in FIG. 4, the fixing member 174 may also be configured to hold the tension member 150 in association with four blocks. That is, when four blocks are inserted into the installation member 172, the tension member 150 is fixed while being deformed by the fixing member 174 consisting of four blocks.

또한, 고정부재(174)는 억지끼움 방식으로 설치부재(172)에 삽입 장착될 수 있다.In addition, the fixing member 174 may be inserted into the installation member 172 by interference fit method.

즉, 안전유닛(170)은 긴장재(150)의 일부분의 파손시에도 골조부재(120)에 압축력을 제공할 수 있도록 안전장치의 역할을 수행할 수 있다.That is, the safety unit 170 may serve as a safety device to provide a compressive force to the skeleton member 120 even when a portion of the tension member 150 is broken.

한편, 안전유닛(170)에 의해 접합부재(140)와 골조부재(120)는 접합된 상태를 유지할 수 있다. 즉, 상기한 바와 같이, 골조부재(120)에 접합부재(140) 측으로 압축력이 가해지므로, 접합부재(140)와 골조부재(120)는 접합된 상태를 유지할 수 있다. On the other hand, the bonding member 140 and the frame member 120 by the safety unit 170 can maintain a bonded state. That is, as described above, since the compressive force is applied to the bonding member 140 side to the skeleton member 120, the bonding member 140 and the skeleton member 120 can maintain a bonded state.

이에 따라, 접합부재(140)의 하단부측에서는 골조부재(120)와 접합부재(140)의 접합을 위한 접합구조(예를 들어, 볼트접합)를 생략할 수 있다. 따라서, 시공성이 향상될 수 있다.Accordingly, the joint structure (eg, bolt joint) for joining the skeleton member 120 and the joint member 140 may be omitted from the lower end side of the joint member 140. Therefore, workability can be improved.

접합부재(140)는 골조부재(120)의 타단부측과 접합되며, 양측면에 설치부재(172)가 삽입 장착되는 장착부(142)를 구비할 수 있다. 또한, 접합부재(140)는 양측면에 구비되는 장착부(142)를 연통시키며, 긴장재(150)가 관통하여 설치되는 관통홀(144)을 구비할 수 있다.The bonding member 140 may be attached to the other end side of the frame member 120, and may include a mounting part 142 on which both sides of the installation member 172 are inserted. In addition, the bonding member 140 may communicate with the mounting portions 142 provided on both side surfaces, and may include a through hole 144 through which the tension member 150 is installed.

즉, 접합부재(140)에는 긴장재(150)가 관통되도록 배치되며, 긴장재(150)는 접합부재(140)의 장착부(142)에 삽입 장착되는 안전유닛(170)을 통해 중앙부가 정착될 수 있다.That is, the tension member 150 is disposed in the bonding member 140 so that the tension member 150 may be fixed to the center portion through the safety unit 170 inserted into the mounting portion 142 of the bonding member 140. .

상기한 바와 같이, 긴장장치(130)를 통해 골조부재(120)의 타단부측에 압축력을 제공할 수 있으므로, 골조부재(120)의 타단부측에 가해지는 수직하중을 상쇄시켜 철골지붕프레임(100)의 구조적 안전성을 향상시킬 수 있다.As described above, since the tension device 130 can provide a compressive force to the other end side of the skeleton member 120, the steel frame frame by offsetting the vertical load applied to the other end side of the skeleton member 120 ( 100) can improve the structural safety.

즉, 골조부재(120)의 자중과 지붕의 하중, 그리고 지붕에 설치되는 설치물에 의한 하중으로부터 가해지는 힘을 긴장장치(130)를 통한 압축력을 통해 감쇠시킬 수 있으므로, 철골지붕프레임(100)의 저항성능 및 처짐강성을 향상시킬 수 있다.That is, since the force applied from the weight of the frame member 120, the load of the roof, and the load of the installation installed on the roof can be attenuated by the compressive force through the tension device 130, the structure of the steel roof frame 100 It can improve resistance performance and deflection stiffness.

한편, 골조부재(120)의 타단부에 가해지는 모멘트를 상쇄시킬 수 있으므로, 골조부재(120)로 H 형강보를 사용할 수 있으므로, 변단면 부재를 사용하지 않을 수 있어 자재확보가 용이하고 시공기간 및 시공비용을 감소시킬 수 있다.On the other hand, since the moment applied to the other end of the frame member 120 can be offset, since the H-shaped steel beam can be used as the frame member 120, it is not possible to use the edge-face member, so the material is easy to secure the construction period and The construction cost can be reduced.

상기에서는 골조부재(120)가 H 형강보인 경우에 대하여 설명하고 있으나, 이에 한정되지 않으며, 변단면 부재를 골조부재로 채용하더라도 변단면 부재와 접합부재의 접합부에서 가해지는 수직하중을 긴장장치를 통해 감쇠시킬 수 있으므로, 골조부재로 변단면 부재가 사용될 수 있다.In the above, the case in which the frame member 120 is an H-shaped steel beam is described. However, the present invention is not limited thereto, and the vertical load applied from the junction between the edge-face member and the joint member is tensioned through the tension device even when the edge-face member is employed as the frame member. Since it can be attenuated, a cross-sectional member can be used as the frame member.

이하에서는 상기한 도면을 참조하여 본 발명의 일실시예에 따른 긴장장치를 구비하는 철골지붕시스템의 작동에 대하여 설명하기로 한다.Hereinafter, with reference to the drawings will be described for the operation of the steel frame roof system having a tension device according to an embodiment of the present invention.

먼저, 긴장재(150)를 각각의 골조부재(120)에 설치된 정착유닛(160)에 장착한다. 이때, 긴장재(150)는 접합부재(140)에 접합 설치된 안전유닛(170)을 관통하도록 장착된다.First, the tension member 150 is mounted to the fixing unit 160 installed in each frame member 120. At this time, the tension member 150 is mounted to penetrate the safety unit 170 bonded to the bonding member 140.

이후, 두개의 정착유닛(160) 중 어느 하나의 정착유닛(160)에 긴장재(150)의 일단부를 정착시킨다. 이를 보다 자세하게 살펴보면, 먼저 지지부재(162)의 설치부(162a)에 4개의 블럭으로 구성된 정착부재(166)를 삽입 장착한다. 이에 따라 고정쐐기의 역할을 수행하는 정착부재(166)에 의해 긴장재(150)의 일단부가 정착유닛(160) 중 하나에 정착된다.Thereafter, one end of the tension member 150 is fixed to one fixing unit 160 of the two fixing units 160. Looking at this in more detail, first, the fixing member 166 consisting of four blocks is inserted into the installation portion 162a of the support member 162. Accordingly, one end of the tension member 150 is fixed to one of the fixing units 160 by the fixing member 166 serving as the fixing wedge.

이후, 나머지 하나의 정착유닛(160) 외측에서 인장잭(미도시)을 통해 긴장재(150)를 인장시킨다. 즉, 긴장재(150)를 긴장시켜 긴장재(150)로부터 압축력이 발생토록 한다.Thereafter, the tension member 150 is tensioned through a tension jack (not shown) at the outside of the other fixing unit 160. That is, the tension member 150 is tensioned to generate a compressive force from the tension member 150.

이후, 긴장재(150)를 나머지 정착유닛(160)에 정착시킨다. 긴장재(150)의 정착은 상기한 바와 같이 정착부재(166)를 통해 이루어진다.Thereafter, the tension member 150 is fixed to the remaining fixing unit 160. Fixing of the tension member 150 is made through the fixing member 166 as described above.

이에 따라, 긴장재(150)로부터 발생되는 압축력은 정착부재(166), 지지부재(162)를 통해 골조부재(120)로 제공된다.Accordingly, the compressive force generated from the tension member 150 is provided to the frame member 120 through the fixing member 166, the support member 162.

따라서, 골조부재(120)와 접합부재(140)와의 접합부에는 도 1에 도시된 바와 같이 압축력이 제공된다.Therefore, the bonding portion of the frame member 120 and the bonding member 140 is provided with a compressive force as shown in FIG.

골조부재(120)에 제공되는 압축력은 골조부재(120) 자체의 하중, 지붕에 의한 하중, 및 지붕에 설치되는 설치물에 의한 하중을 감쇠시킬 수 있다. 즉, 지면을 향하여 발생되는 하중에 의한 힘이 압축력에 의한 상부측으로 발생되는 힘에 의해 감쇠될 수 있다.The compressive force provided to the frame member 120 may attenuate the load of the frame member 120 itself, the load by the roof, and the load by the installation installed on the roof. That is, the force due to the load generated toward the ground can be attenuated by the force generated toward the upper side by the compressive force.

이에 따라, 골조부재(120)의 상호간의 접합부에서 발생되는 수직하중을 감쇠시켜 골조부재(120)의 구조적 안전성을 확보할 수 있다. 즉, 지붕철골시스템(100) 의 처짐을 감소시켜 하중에 대한 지붕철골시스템(100)의 저항성능 및 처짐강성을 향상시킬 수 있다.Accordingly, it is possible to secure the structural safety of the frame member 120 by attenuating the vertical load generated in the joint portion of the frame member 120. That is, by reducing the deflection of the roof steel frame system 100 can improve the resistance performance and deflection rigidity of the roof steel frame system 100 to the load.

한편, 골조부재(120)의 구조적 안전성을 확보할 수 있으므로, 일반적으로 골조부재(120)로 사용되는 변단면 부재를 채용하지 않고, H 형강보를 골조부재(120)로 채용할 수 있다.On the other hand, since it is possible to ensure the structural safety of the frame member 120, it is possible to employ the H-shaped steel beam as the frame member 120, without employing the side cross-section member generally used as the frame member (120).

또한, H 형강보를 골조부재(120)로 채용할 수 있으므로 자재확보가 원활해지며, 시공기간과 시공비용을 감소시킬 수 있다.In addition, since the H-shaped steel beam can be employed as the frame member 120, material securing is smooth, and construction period and construction cost can be reduced.

한편, 상기한 바와 같이 긴장재(150)의 긴장이 완료되면, 긴장재(150)를 안전유닛(170)에 정착시킨다. 즉, 긴장재(150)가 관통하는 설치부재(172)에 고정부재(174)를 삽입 장착하여 긴장재(150)의 중앙부가 설치부재(172)에 정착되도록 한다.On the other hand, when the tension of the tension member 150 is completed as described above, the tension member 150 is fixed to the safety unit 170. That is, the fixing member 174 is inserted into the installation member 172 through which the tension member 150 penetrates to fix the central portion of the tension member 150 to the installation member 172.

이와 같이, 긴장재(150)의 중앙부가 안전유닛(170)에 정착됨으로써, 긴장재(150)의 파단시 파단이 발생되지 않은 긴장재(150) 측은 안전유닛(170)과 정착유닛(160)에 의해 계속해서 압축력을 제공할 수 있다.As such, since the central portion of the tension member 150 is fixed to the safety unit 170, the tension member 150 that is not broken when the tension member 150 is broken continues by the safety unit 170 and the fixing unit 160. To provide a compressive force.

더하여, 안전유닛(170)에 긴장재(150)가 정착되므로, 골조부재(120)와 접합부재(140)의 접합을 보다 용이하게 할 수 있다. 즉, 긴장장치(130)에 의해 골조부재(120)와 접합부재(140)의 하단부 접합이 가능하므로, 골조부재(120)와 접합부재(140)의 하단부측은 접합구조(예를 들어 볼트접합)를 채용하지 않을 수 있다. 따라서, 시공성이 향상될 수 있다.In addition, since the tension member 150 is fixed to the safety unit 170, the joint member 120 and the bonding member 140 may be more easily bonded. That is, since the lower end of the skeleton member 120 and the joining member 140 can be joined by the tension device 130, the lower end side of the framework member 120 and the joining member 140 is a joining structure (for example, bolted joint) May not be employed. Therefore, workability can be improved.
