그레이팅 고정구{Grating fastener}Grating fastener

본 발명은 그레이팅 고정구에 관한 것으로, 보다 상세하게는 구조개선을 통하여 그레이팅 고정작업을 보다 단순화시킨 그레이팅 고정구에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grating fixture, and more particularly, to a grating fixture that simplifies a grating fixation operation through structural improvement.

일반적으로 그레이팅(Grating)은 상부가 개방된 배수로나 환기구 등에 설치되어 유체의 유동은 허용하되, 보행자나 비교적 큰 부피의 물체가 배수로나 환기구 등으로 유입 또는 추락하는 것을 방지하도록 격자형의 구조로 형성된 자재이다.In general, the grating is formed in a grid-like structure so as to prevent the flow of fluid, such as pedestrians or objects of relatively large volume, from entering or falling into a drainage passage or a ventilating opening, Material.

이러한 그레이팅은 선박이나 해양구조물에 형성되는 배수구나 환기구 그리고 작업통로 등에도 사용되고 있다.Such gratings are also used in drainage, ventilation, and work passages formed in ships and offshore structures.

한편, 선박이나 해양구조물의 경우, 높은 파도에 의해 선체가 심하게 요동할 때, 그레이팅이 선체로부터 분리되는 것을 방지할 수 있도록 그레이팅 고정구를 이용하여 그레이팅을 선체에 고정하고 있다.On the other hand, in the case of a ship or an offshore structure, the grating is fixed to the hull by means of a grating fastener so as to prevent the grating from separating from the hull when the hull is severely rocked by a high wave.

도 1은 종래 그레이팅 고정구의 구조를 나타낸 단면도이다.1 is a cross-sectional view showing the structure of a conventional grating fixture.

종래의 그레이팅 고정구는 그레이팅(10)이 설치되는 구조물(S)에 고정되는 고정핀(20)과, 그레이팅(10)을 상부에서 가압하여 고정하도록 상기 고정핀(20)과 나사결합되는 가압헤드(30)로 구성되어 있다.The conventional grating fixture includes a fixing pin 20 fixed to a structure S on which a grating 10 is mounted and a pressing head 20 screwed to the fixing pin 20 to press and fix the grating 10 at the upper portion 30).

이러한 종래의 그레이팅 고정구를 이용하여 그레이팅을 고정하기 위해서는, 먼저 고정핀을 구조물에 설치한 다음, 가압헤드를 고정핀에 조립하여 그레이팅을 고정하는 방식으로 작업이 이루어지게 된다.In order to fix the grating by using the conventional grating fixture, the fixing pin is first installed on the structure and then the pressing head is fixed to the fixing pin to fix the grating.

즉, 종래의 그레이팅 고정구를 이용하여 그레이팅 작업을 실시하는 경우, 고정핀 설치단계와 가압헤드를 이용한 그레이팅 고정단계로 작업이 구분되어 따로 실시해야 하며, 더욱이 고정핀 설치단계와 그레이팅 조립단계의 사이에는 고정핀에 조립될 가압헤드와 가압헤드를 회전시킬 도구를 준비하고 배치하기 위한 시간이 요구되므로 생산성이 저하되는 문제점이 있다.That is, when performing the grating operation using the conventional grating fixture, the work must be separately performed by the fixing pin mounting step and the grating fixing step using the pressing head. Further, between the fixing pin mounting step and the grating mounting step There is a problem in that the time required for preparing and arranging a pressing head to be assembled to the fixing pin and a tool for rotating the pressing head is required, resulting in a decrease in productivity.

본 발명에 따른 그레이팅 고정구는 고정부재(110)와 가압부재(120) 및 작동부재(130)로 구성되며, 상기 고정부재(110)와 가압부재(120) 및 작동부재(130)는 상호 결합되어 하나의 조립체를 형성하게 된다.The grating fixture according to the present invention comprises a fixing member 110, a pressing member 120 and an operating member 130. The fixing member 110, the pressing member 120, and the operating member 130 are coupled to each other Thereby forming one assembly.

상기 고정부재(110)는 그레이팅이 배치되는 구조물에 고정되는 몸체(111)와, 상기 작동부재(130)와 결합되어 작동부재(130)를 지지하는 가이드봉(112)으로 구성된다.The fixing member 110 includes a body 111 fixed to a structure where a grating is disposed and a guide rod 112 coupled to the operation member 130 to support the operation member 130.

보다 구체적으로, 상기 몸체(111)는 전체적으로 수직방향으로 연장되는 봉형상으로 형성되되, 하단부(111a)가 상단부(111b)에 비하여 상대적으로 작은 직경의 단면을 갖도록 형성되어 있다. 이때 하단부(111a)의 외면에는 오른나사로 이루어지는 수나사(113)가 형성되어 구조물에 나사결합되며, 상면에는 상기 수나사(113)의 체결방향 즉, 오른쪽 방향 회전에 대해서만 회전력을 전달하는 구조를 갖는 제1 래칫형 기어(114)가 형성되어 있다.More specifically, the body 111 is formed as a rod extending in the vertical direction as a whole, and the lower end portion 111a is formed to have a relatively small diameter section as compared with the upper end portion 111b. At this time, on the outer surface of the lower end portion 111a, a male screw 113 made of a right screw is formed and screwed to the structure, and on the upper surface, a first force transmitting structure for transmitting the rotational force only to the fastening direction of the male screw 113, A ratchet type gear 114 is formed.

물론, 상기 하단부(111a)의 외면에 왼나사로 이루어진 수나사(113)를 형성하고, 상기 제1 래칫형 기어(114)가 좌회전에 대해서만 회전력을 전달하는 구조를 갖도록 구성될 수도 있으며, 이러한 경우, 후술될 가압부재(120)의 내면에 형성되는 암나사도 왼나사로 이루어지게 된다.Of course, the first ratchet gear 114 may be configured to have a structure in which a male screw 113 made of a left-hand thread is formed on the outer surface of the lower end portion 111a, and the first ratchet gear 114 transmits rotational force only to the leftward rotation. The female screw formed on the inner surface of the pressing member 120 to be screwed is also made of the left screw thread.

상기 가이드봉(112)은 몸체(111)의 상면으로부터 수직 상방향으로 연장되게 형성되며, 이러한 가이드봉(112)의 최상단부에는 작동부재(130)의 이탈을 방지하는 걸림턱(115)이 형성되어 있다. 한편 상기 걸림턱(115)은 가이드봉(112)과 일체형의 구조로 구성될 수도 있으나, 가이드봉(112)과 작동부재(130)의 조립을 위해서는 별도 제작된 걸림턱(115)을 가이드봉(112)의 상단부에 조립하여 고정하는 것이 바람직하다. 참고로 상기 걸림턱(115)과 가이드봉(112)의 조립은 별도의 볼트를 이용하여 걸림턱(115)을 가이드봉(112)에 고정하거나, 걸림턱(115)를 가이드봉(112)에 용접하여 고정하거나, 걸림턱(115)을 가이드봉(112)에 직접 나사결합하는 방식으로 구현될 수 있다.The guide rod 112 is formed to extend vertically upward from the upper surface of the body 111. A stopping protrusion 115 for preventing the release of the operation member 130 is formed at the upper end of the guide rod 112 . In order to assemble the guide rod 112 and the actuating member 130, a separate jaw 115 is inserted into the guide rod 112, 112 at the upper end thereof. The hooking jaw 115 may be fixed to the guide rod 112 by using a separate bolt or the hooking jaw 115 may be fixed to the guide rod 112 Or may be realized by a method in which the engaging jaw 115 is screwed directly to the guide rod 112.

이러한 가이드봉(112)은 몸체(111)의 외측을 감싸는 구조로 결합되는 가압부재(120)와 가이드봉(112)의 사이로 작동부재(130)가 배치되는 공간을 형성할 수 있도록 몸체(111)의 직경에 비하여 작은 직경으로 형성된다.The guide rod 112 has a body 111 so as to form a space in which the actuating member 130 is disposed between the pressing member 120 and the guide rod 112, As shown in FIG.

상기 가압부재(120)는 작동부재(130)의 회전에 의해 하강하면서 그레이팅을 고정하는 것으로, 상기 고정부재(110)가 내부로 삽입되도록 전체적으로 원통형의 구조로 형성되되, 상단부에는 그레이팅의 가압을 위한 가압날개(121)가 형성된 것으로 구성된다.The pressing member 120 is lowered by the rotation of the actuating member 130 and fixes the grating. The pressing member 120 is formed in a generally cylindrical structure so that the fixing member 110 is inserted therein. And a pressurizing blade 121 is formed.

이때 상기 가압날개(121)는 가압부재(120)의 상단부에서 가압부재(120)의 원주를 따라 둥글게 연장되는 환형의 구조로 형성될 수 있다.At this time, the pressing blade 121 may be formed in an annular shape extending roundly along the circumference of the pressing member 120 at the upper end of the pressing member 120.

한편, 상기 가압부재(120)의 내면에는 작동부재(130)와의 나사결합을 위한 암나사(122)가 형성되며, 상기 암나사(122)는 몸체(111)의 하단부에 형성된 수나사(113)와 동일하게 오른나사로 이루어진다.On the other hand, on the inner surface of the pressing member 120, a female screw 122 for screwing with the operating member 130 is formed. The female screw 122 is formed in the same manner as the male screw 113 formed on the lower end of the body 111 Right-hand screw.

상기 작동부재(130)는 작업자의 조작에 의해 회전하면서 고정부재(110)를 구조물에 고정하고 더불어 가압부재(120)를 하강시키는 것으로, 상기 가이드봉(112)을 따라 상하로 이동하도록 가이드봉(112)에 결합된다.The actuating member 130 is fixed to the structure while rotating the actuating member 130 while the actuating member 130 is rotated by the operation of the operator and the actuating member 130 is moved downward along the guide rod 112, 112).

이러한 작동부재(130)의 저면에는 제1 래칫형 기어(114)에 대응하여 맞물리는 구조를 갖는 제2 래칫형 기어(131)가 형성된다. 이와 같은 제1,2 래칫형 기어(114,131)에 의하면, 작동부재(130)의 어느 일방향 회전에 대해서는 고정부재(110)가 함께 회전하고, 반대 방향의 회전에 대해서는 작동부재(130)만 회전하게 된다.A second ratchet type gear 131 having a structure to be engaged with the first ratchet type gear 114 is formed on the bottom surface of the operating member 130. According to the first and second ratchet type gears 114 and 131, the fixing member 110 rotates with respect to any one direction rotation of the operation member 130 and only the operation member 130 rotates with respect to the rotation in the opposite direction do.

또한, 상기 작동부재(130)의 외면에는 가압부재(120)의 내면에 형성된 암나사(122)와 체결되는 수나사(132)가 외면에 형성된다.A male screw 132 is formed on the outer surface of the operation member 130 and is fastened to the female screw 122 formed on the inner surface of the pressing member 120.

또한, 상기 작동부재(130)의 상면에는 작동부재(130)를 회전시키기 위한 회전도구가 결합되는 다각형의 홈(133) 또는 돌기가 형성된다.A polygonal groove 133 or protrusion is formed on the upper surface of the actuating member 130, to which a rotating tool for rotating the actuating member 130 is coupled.

한편 도 5에는 육각형의 모양을 갖는 홈(133)이 작동부재(130)의 상면에 형성된 구조가 도시되어 있으며, 이처럼 작동부재(130)의 상면에 육각형 모양의 홈(133)이 형성된 경우, 회전도구로는 렌치가 이용될 수 있다. 다만 작동부재(130)의 중앙부를 가이드봉(112)이 관통하는 관계로 일반적인 렌치를 회전도구로 이용할 수 없으며, 렌치의 끝단부를 형성하는 육각 단면의 중앙부에 가이드봉(112)이 삽입되는 홀이 형성되도록 별도 제작된 렌치가 회전도구로 이용할 수 있다.
5, a hexagonal groove 133 is formed on the upper surface of the actuating member 130. When the hexagonal groove 133 is formed on the upper surface of the actuating member 130, A wrench can be used as a tool. However, since the guide rod 112 passes through the center of the operating member 130, a general wrench can not be used as a rotating tool, and a hole into which the guide rod 112 is inserted is formed at the center of the hexagonal cross- A separately manufactured wrench can be used as a rotating tool to form.

상기와 같이 구성된 그레이팅 고정구를 이용하여 그레이팅을 선체와 같은 구조물에 고정하는 과정을 설명하도록 한다.A process of fixing the grating to a structure such as a hull using the grating fixture configured as described above will be described.

도 6은 본 발명에 따른 그레이팅 고정구를 이용하여 그레이팅을 고정하는 과정을 보인 공정도를 도시하고 있다.FIG. 6 is a process diagram showing a process of fixing a grating using a grating fixture according to the present invention.

본 발명에 따른 그레이팅 고정구는 고정부재(110)와 가압부재(120) 및 작동부재(130)가 상호 결합된 하나의 조립체로 제공되며, 이처럼 하나의 조립체로 이루어진 그레이팅 고정구를 그레이팅(10)의 고정이 요구되는 위치에 배치한다.The grating fixture according to the present invention is provided as one assembly in which the fixing member 110, the pressing member 120 and the actuating member 130 are coupled to each other, and the grating fixture composed of one assembly is fixed to the grating 10 Is placed at the required position.

이후, 작동부재(130)에 회전도구를 결합하고, 회전도구를 이용하여 작동부재(130)를 오른쪽 방향으로 회전시킨다. 물론 고정부재(110)와 가압부재(120) 및 작동부재(130)에 왼나사를 형성한 경우, 작동부재(130)를 왼쪽 방향으로 회전시키게 된다.Thereafter, the rotating tool is engaged with the operating member 130, and the operating member 130 is rotated in the clockwise direction using the rotating tool. Of course, when the left and right threads are formed on the fixing member 110, the pressing member 120, and the operation member 130, the operation member 130 is rotated in the left direction.

이처럼 작동부재(130)가 오른쪽 방향으로 회전하는 경우, 제1,2 래킷형 기어(114,131)가 서로 맞물려 작동부재(130)의 회전력이 고정부재(110)로 그대로 전달되므로, 고정부재(110)가 작동부재(130)와 함께 회전하게 되며, 이러한 고정부재(110)의 회전에 의하여 고정부재(110)의 하단부에 형성된 수나사(113)가 구조물(S)에 삽입 고정된다.The first and second rack gears 114 and 131 are engaged with each other so that the rotational force of the actuating member 130 is transmitted to the stationary member 110 as it is. And the male screw 113 formed at the lower end of the fixing member 110 is inserted and fixed to the structure S by the rotation of the fixing member 110. [

한편, 고정부재(110)가 구조물(S)에 보다 용이하게 체결될 수 있도록 하기 위하여 구조물(S)에 미리 구멍을 가공해 놓을 수도 있다.On the other hand, a hole may be previously formed in the structure S so that the fixing member 110 can be more easily fastened to the structure S.

상기와 같은 작동부재(130)의 오른쪽 방향 회전으로 인하여 고정부재(110)가 구조물(S)에 결합되며, 이러한 과정에서 가압부재(120)는 작동부재(130)와 함께 회전하면서 이동하거나, 그레이팅(10)에 접촉한 경우 작동부재(130)와 함께 회전하지 않고 그 자리를 유지하게 된다.The fixing member 110 is coupled to the structure S by the rotation of the operating member 130 in the right direction. In this process, the pressing member 120 moves while rotating together with the operating member 130, (Not shown in the drawings).

상기와 같이 고정부재(110)가 구조물(S)에 설치된 후, 작업자는 회전도구를 이용하여 작동부재(130)를 왼쪽 방향으로 회전시킨다.After the fixing member 110 is installed on the structure S as described above, the operator rotates the operation member 130 in the leftward direction using the rotating tool.

이처럼 작동부재(130)가 왼쪽 방향으로 회전하는 경우, 제1,2 래킷형 기어(114,131)는 작동부재(130)의 회전력을 고정부재(110)를 전달하지 못하게 된다. 따라서 작동부재(130)의 왼쪽 방향 회전시 고정부재(110)는 구조물(S)에 체결된 상태를 유지하는 반면, 가압부재(120)와 나사결합된 작동부재(130)는 상승하게 된다.When the actuating member 130 rotates in the left direction, the first and second rack gears 114 and 131 can not transmit the rotational force of the actuating member 130 to the stationary member 110. Therefore, when the operation member 130 is rotated to the left, the fixing member 110 maintains the state of being fastened to the structure S, while the operation member 130 screwed to the pressing member 120 is moved upward.

한편, 상승하는 작동부재(130)의 상면이 걸림턱(115)과 접촉하게 되면, 작동부재(130)의 상승이 억제되며, 작동부재(130)의 상승이 억제된 상태에서 작동부재(130)를 계속해서 왼쪽 방향으로 회전시킴에 따라 가압부재(120)는 하강하게 되며, 이러한 가압부재(120)의 하강에 의하여 가압날개(121)가 그레이팅(10)을 가압 고정하게 된다.The upward movement of the actuating member 130 is suppressed and the upward movement of the actuating member 130 is suppressed while the upward movement of the actuating member 130 is suppressed, The pressing member 120 is lowered and the pressing blade 121 presses and fixes the grating 10 by the lowering of the pressing member 120. [

상술한 바와 같이 본 발명에 따른 그레이팅 고정구는 작동부재(130)를 오른쪽 방향으로 회전시키는 것에 의하여 고정부재(110)의 설치작업이 이루어지고, 이어서 작동부재(130)를 왼쪽 방향으로 회전시키는 것에 의하여 가압부재(120)에 의한 그레이팅 고정작업이 이루어지게 되므로, 결국 두 작업을 연속적으로 실시할 수 있어 그레이팅 고정작업에 요구되는 시간을 단축할 수 있는 이점이 있다.
As described above, in the grating fixture according to the present invention, the fixing member 110 is installed by rotating the operating member 130 in the right direction, and then, by rotating the operating member 130 in the leftward direction Since the grating fixing operation by the pressing member 120 is performed, it is possible to continuously perform the two operations, which is advantageous in that the time required for the grating fixing operation can be shortened.

본 발명은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.
It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
