제 2도에는 본 고안에 따른 경량채널(1a) (1b) (1c) (1d)이 도시되어 있다. 상기 경량채널(1a) (1b) (1c) (1d)은 중앙플랜지(3)와 양측플랜지(5)중의 어느하나에 절곡보강부(7)가 형성된것으로서, 제2도의 제2a도에 도시된 것은 ㄷ 형 몸체(2)의 중앙플랜지(3)에 절곡보강부(7)가 형성된 것이다. 그리고, 이는 양측플랜지(5)의 내측으로 립부(14)가 형성된다.2 shows a lightweight channel 1a, 1b, 1c, 1d according to the present invention. The lightweight channels 1a, 1b, 1c, and 1d are formed with bent reinforcement portions 7 in one of the central flange 3 and the two side flanges 5, as shown in FIG. 2a of FIG. It is a bending reinforcement 7 is formed in the central flange (3) of the c-shaped body (2). And, this is a lip portion 14 is formed inside the two flanges (5).
그리고, 제2도의 제2b도에 도시된 것은 ㄷ 형 몸체(2)의 중앙플랜지(3)와 양측플랜지(5)에 각각 절곡보강부(7)가 형성되며, 양측플랜지(5)의 내측으로 립부(14)가 형성된다.And, in FIG. 2b of FIG. 2, the bent reinforcement 7 is formed in the central flange 3 and the both flanges 5 of the c-shaped body 2, respectively, and the inner side of the two flanges 5, respectively. Lip 14 is formed.
또한, 제2도의 제2c도에 도시된 것은 ㄷ 형 몸체(2)의 중앙플랜지(3)에 복수개의 절곡보강부(7)가 형성되고, 양측플랜지(5)의 내측으로 립부(14)가 형성되며, 상기 립부(14)의 선단에는 보강플랜지(9)가 각각 형성된다.In addition, shown in FIG. 2C of FIG. 2, a plurality of bending reinforcement portions 7 are formed in the central flange 3 of the c-shaped body 2, and the lip portions 14 are formed inside the two flanges 5. The reinforcing flanges 9 are formed at the ends of the lip portions 14, respectively.
그리고, 제2도의 도시된 것은 ㄷ 형 몸체(2)의 중앙플랜지(3)에 절곡보강부(7)가 복수개 형성되고, 양측플랜지(5)의 내측으로 립부(14)가 형성된 구조를 갖는다.2, the bending reinforcement portion 7 is formed in the central flange 3 of the c-shaped body 2, and the lip portion 14 is formed inside the two side flanges 5, respectively.
이런한 구성으로된 본 고안의 작용및,효과에 대하여 설명하면 다음과 같다.Referring to the operation and effects of the present invention having such a configuration as follows.
본 고안에 따른 경량채널(1a)(1b)(1c)(1d)은 중앙플랜지(3)와 양측플랜지(5)의 절곡보강부(7)가 구조적인 강도를 증가시키게 된다.In the lightweight channels 1a, 1b, 1c, and 1d according to the present invention, the bending reinforcement portions 7 of the central flange 3 and the two flanges 5 increase the structural strength.
이러한 본 고안의 경량채널(1a)(1b)(1c)(1d)이 종래에 비하여 구조적으로 강한 것을 예시하기 위하여 좌굴응력(bucking stress)시험을 실시하고, 이를 제 3도에 도시하였다. 각각의 실험에 사용된 부재의 길이는 50 - 3,000mm 이었으며, 본 실험에서는 소성변형은 무시하고, 부위별 물성치는 균일한 것으로 가정하여 종래의 두께 1mm의 열연강판을 절곡한 경량채널(10b)(제1도의 제1b도에 도시함.)과, 종래의 두께 1.2mm의 열연강판을 절곡한 경량채널 (10c)(제1c도에 도시함.) 및, 본 고안에 따른 0.6mm두께의 중앙플랜지 (3)에 절곡보강부(7)를 형성한 경량채널(1a)(제2b도에 도시함.)과 본 고안에 따른 0.6mm두께의 중앙플랜지(3)에 복수개의 절곡보강부(7)를 형성하고, 립부(14)의 선단에는 보강플랜지(9)가 형성된 경량채널(1c)(제 2c도에 도시함.)을 이용하여 실험을 실시하였다.In order to illustrate that the light weight channels 1a, 1b, 1c, and 1d of the present invention are structurally strong as compared with the related art, a bucking stress test is performed and this is illustrated in FIG. 3. The length of the members used in each experiment was 50-3,000mm, and in this experiment, the plastic channel was bent and the light weight channel 10b (b) was bent in a conventional hot rolled steel sheet having a thickness of 1 mm, assuming that the physical properties of each part were uniform. 1b of FIG. 1), a lightweight channel 10c (shown in FIG. 1c) of a conventional 1.2 mm thick hot rolled steel sheet, and a 0.6 mm thick central flange according to the present invention. (3) a plurality of bending reinforcements (7) in the lightweight channel (1a) (shown in Figure 2b) having the bending reinforcement (7) formed in the central flange (3) of 0.6mm thickness according to the present invention The experiment was carried out using the lightweight channel 1c (shown in FIG. 2C) in which the reinforcing flange 9 was formed at the tip of the lip portion 14.
제 3도에서는 알 수 있는 바와, 각각의 단면구조별 좌굴응력분포를 살펴보면, 제 1b도에 도시된 종래의 경량채널(10b)은 130 - 200Mpa를 나타내고, 제1c도에 도시된 종래의 경량채널(10c)은 150 - 300Mpa를 나타내는 반면, 본 고안에 따른 제 2도의 제2a도, 제2b도, 제2c도의 경량채널(1a)(1b)(1c)은 길이 100 -1,300mm에서 종래의 경량채널(10b)(10c)보다 현저히 높은 260 - 650Mpa를 나타내고 있다.As can be seen from FIG. 3, when looking at the buckling stress distribution for each cross-sectional structure, the conventional lightweight channel 10b shown in FIG. 1b represents 130-200 Mpa, and the conventional lightweight channel shown in FIG. 10c represents 150-300Mpa, while the light weight channels 1a, 1b and 1c of FIGS. 2a, 2b and 2c of FIG. 2 according to the present invention have a conventional light weight at a length of 100 -1,300mm. It is 260-650 Mpa which is markedly higher than the channels 10b and 10c.
이는 단면구조의 변화에 따른 내력의 증가를 보이고 있는 것임을 알수 있다.This can be seen that the increase in strength with the change in cross-sectional structure.
그러나, 길이 2,000 - 2,600mm의 범위에서는 종래의 기술과 유사한 150 - 200Mpa를 나타내는데, 이는 길이의 증가에 따라서 휨-비틀림(flexural-torsional buckling)강성이 비슷하기 때문이다.However, in the range of 2,000-2,600 mm in length, it shows 150-200 Mpa, which is similar to the prior art, because the flexural-torsional buckling stiffness is similar with increasing length.
한편, 제2c도에 도시된 본 고안의 경량채널(1c)은 립부(14)에 보강플랜지(9)를 형성한 것으로서 제2a도 및 제2b도에 도시된 경량채널(10b)(10c)보다 50 - 100Mpa 정도 좌굴내력이 우수한 것으로 나타난다.Meanwhile, the light weight channel 1c of the present invention shown in FIG. 2c has a reinforcing flange 9 formed on the lip portion 14, and is lighter than the light weight channels 10b and 10c shown in FIGS. 2a and 2b. The buckling strength is excellent about 50-100Mpa.
상기에서와 같이 본 고안의 경량채널(1a)(1b)(1c)에 의하면, 각각의 단면형상에 따라서 종래의 열연강판을 이용한 경량채널(10b)(10c)보다 현저히 가벼운 중량으로도 큰 강도를 유지할 수 있는 것이다.As described above, according to the light weight channels 1a, 1b, and 1c of the present invention, the strength is increased even at a significantly lighter weight than the light weight channels 10b and 10c using the conventional hot-rolled steel sheet according to each cross-sectional shape. It is sustainable.
이하에서는, 본 고안의 경량채널(1c), 특히 제2c도에 도시된 바와 같은 경량채널(1c)을 이용하여 내벽패널(p)을 고정시키는 작동을 제 4도에 따라서 설명한다.Hereinafter, the operation of fixing the inner wall panel p using the light weight channel 1c of the present invention, particularly the light weight channel 1c as shown in FIG. 2c, will be described according to FIG.
제4a도에 도시된 바와 같이, 본 고안의 경량채널(1c)은 립부(14)의 보강플랜지(9)상에 석고보드등과 같은 내벽패널(p)을 부착하여 고정시키게 된다. 따라서, 이러한 구성은 경량채널(1c)이 내벽패널(p)의 일측에 위치된다.As shown in Figure 4a, the lightweight channel 1c of the present invention is to be fixed by attaching the inner wall panel (p) such as gypsum board on the reinforcing flange 9 of the lip (14). Therefore, in this configuration, the light weight channel 1c is located on one side of the inner wall panel p.
제4b도와 제4d도에는 내벽패널(p)의 일측에 장착된 경량채널(1c)이 각각 2 방향과 3방향으로 지주(20)에 의해서 고정되어 있다. 따라서, 이러한 구성은 경량채널(1c)과 지주(20)를 이용하여 내벽패널(p)을 여러방향으로 고정시킬 수 있는 것이다4b and 4d, the lightweight channel 1c mounted on one side of the inner wall panel p is fixed by the support 20 in two directions and three directions, respectively. Therefore, this configuration can be fixed to the inner wall panel (p) in various directions using the light weight channel (1c) and the support (20).
상술한 바와 같이 본 고안에 따른 냉연강판을 이용한 경량채널에 의하면, 단면의 두께가 종래의 두께보다 1/2이상 감소된 0.6mm의 두께로도 종래의 1.2mm두께의 열연강판을 이용한 경량채널보다 좌굴강도가 현저하게 커지기 때문에 전체적으로 철강재의 소모량을 감소시킬수 있음과 동시에, 중량의 감소에 따른 현장운반작업의 용이함은 물론, 시공성의 향상도 이룰 수 있는 실용상의 효과가 얻어지는 것이다.As described above, according to the light weight channel using the cold rolled steel sheet according to the present invention, even when the thickness of the cross section is 0.6 mm, the thickness of which is reduced by 1/2 or more than the conventional thickness, compared to the light weight channel using the conventional hot rolled steel sheet of 1.2 mm thickness. Since the buckling strength is remarkably large, the overall consumption of steel can be reduced, and the practical effect can be achieved as well as the ease of field transportation work due to the weight reduction, as well as the workability.
