Description

고소작업장의 추락방지용 안전난간대{Safety railing protection for falling}Safety Railing Protection for Falls in Aerial Workplace

본 발명은 고소작업장의 추락방지용 안전난간대에 관한 것으로, 특히 상부로는 미는 힘을 작용시키고 하부로는 당기는 힘을 작용시켜 견고한 지지력을 발생시키며 구성요소가 개별적으로 체결되어 유지보수가 용이하며 반영구적으로 사용가능한 고소작업장의 추락방지용 안전난간대에 관한 것이다.The present invention relates to a safety handrail for preventing the fall of a loft workplace, in particular, a pushing force to the upper and a pulling force to the lower to generate a solid support force, the components are individually fastened and easy to maintain and semi-permanently The present invention relates to a safety handrail for preventing the fall of a usable aerial platform.

도로공사 개설시 수반되는 모든 교량을 건설함에 있어서 교각건립중 교각 상단 교좌지점 작업에 있어 작업자의 추락을 방지하기 위해 난간을 설치하게 된다.In constructing all bridges involved in the construction of road construction, handrails will be installed to prevent the worker from falling in the work of the upper bridge point during the construction of the bridge.

지금까지의 고소 및 교각 작업장에 설치되는 난간은 다음과 같이 두 가지의 형태로 제공되어 왔다.The railings installed in the aerial and piers workshops have been provided in two forms as follows.

먼저 강관파이프를 재료로 하여 사각 틀 형태의 난간대를 지상에서 제작하여 이를 크레인으로 교각 상단에 올려놓고 가설시킨 형태로서의 난간대이다.First of all, it is a handrail made by constructing a square frame railing on the ground using steel pipe pipe and placing it on the top of the piers with a crane.

상기와 같은 난간대는 다음과 같은 문제점이 있다.The balustrade as described above has the following problems.

첫째, 난간대 전체가 교각 상단에 고정되어 있지 않고 자체 무게로만 설치된 것이기 때문에 약간의 힘을 가하게 되면 도괴(倒壞)될 위험이 있으며, 특히 강풍에 의해 쉽게 도괴되어 안전사고를 일으킬 수 있는 것이다.First, because the whole railing is not fixed to the top of the piers, but installed only by its own weight, there is a risk of collapse when a little force is applied.

둘째, 난간대 전체를 비계용 강관파이프로 사용함으로서 다루기가 불편하다.Second, it is inconvenient to handle by using the whole railing pipe as scaffolding steel pipes.

셋째, 난간대의 제작 및 설치에 따른 숙련작업자를 필요로 하여 시설인원을 증가시키게 되어 비용이 많이 소요되게 된다.Third, it requires a skilled worker according to the manufacture and installation of handrails, which increases the number of facilities, which is expensive.

넷째, 난간대의 해체 작업시 매우 위험할 뿐더러 난간대의 운반시 장비를 필요로 하게 된다.Fourth, the dismantling work of the handrail is very dangerous and requires the equipment for transportation of the handrail.

다음은 난간대를 설치하기 위해 교각 상부에 앙카를 박고 이를 통해 파렛트를 고정하여 난간대를 세우는 것이다.The next step is to erect the railing by anchoring the top of the piers in order to install the railings and fixing the pallets through them.

상기와 같은 난간대는 다음과 같은 문제점이 있다.The balustrade as described above has the following problems.

첫째, 난간대가 고정되나 흔들림이 발생하게 되고 난간대를 볼트 너트로 재 체결하여 세움으로서 설치가 번거롭다.First, the handrail is fixed but shaking occurs, and the installation is cumbersome by re-entering the handrail with bolt nuts.

둘째, 교각에 설치된 앙카의 재활용이 불가능하고 앙카를 빼내지 못함으로서 녹물이 발생하여 교각의 품질 및 수명에 악영향을 준다.Secondly, it is impossible to recycle anchors installed on the bridges, and the anchors cannot be pulled out, resulting in rust, which adversely affects the quality and life of the bridges.

셋째, 앙카를 설치할 때 숙련된 기능공을 필요로 하게 되고 앙카의 설치가 착암기를 통해 이루어지게 되어 교각의 파손시키는 문제점이 발생된다.Third, when the anchor is installed, skilled skilled workers are required, and the installation of the anchor is made through a rock drill, which causes a problem of breaking the piers.

넷째, 앙카를 설치함으로 난간대 설치비용이 상승된다.Fourth, the installation cost of railings increases by installing anchors.

이러한 문제점을 보완하고자 대한민국 특허출원번호 제 10-1998-0009958호가 제안되었다.To solve this problem, Korean Patent Application No. 10-1998-0009958 has been proposed.

그리고 상기 수직파이프(10)와 걸림지지대(50)의 결합을 위하여 끝단으로만 숫나사(112a)가 형성된 고정핀(112)과 숫나사(112a)와 체결되는 너트(113)를 이용하여 회동가능하도록 체결고정되어 형성된다.And it is fastened so as to be rotatable by using the fixing pin 112 and the nut 113 which is fastened to the male screw (112a) formed with the male screw (112a) only at the end for coupling the vertical pipe (10) and the locking support (50). It is fixed and formed.

상기 걸림지지대(50)는 반대측 수직파이프(10)에 대하여 동일한 구성을 갖으며 마주보며 대칭되도록 체결고정되어 형성되어 안전난간대(60)이 구성된다.The locking support 50 has the same configuration with respect to the opposite vertical pipe 10 and is fastened and formed to be symmetrical to face the safety handrail 60 is configured.

도 3은 상기와 같은 안전난간대(60)의 전체적인 결합구성을 나타내고 있다. 3 shows the overall coupling configuration of the safety railing 60 as described above.

상기와 같이 구성된 본 발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

상기 도 3과 도 4에 도시된 바와 같이 제1 길이조절너트(32)를 상단 고정바(31)와 상단 이동바(33)를 밀어내도록 회동시키면 마주보며 대칭되는 수직파이프(10)의 상단은 고정바(31)가 외측으로 이동하게 되어 간격이 벌어지며 멀어지게 된다. As shown in FIGS. 3 and 4, when the first length adjusting nut 32 is rotated to push the upper fixing bar 31 and the upper moving bar 33, the upper end of the vertical pipe 10 facing and symmetrical is Fixing bar 31 is moved to the outside and the gap is apart and away.

이때 상기 고정바(31)와 끼움대(11)는 힌지 체결로 인하여 수직파이프(10)의 간격이 벌어지더라도 자연스러운 회동을 수반하게 된다.At this time, the fixing bar 31 and the fitting table 11 are accompanied by a natural rotation even if the gap between the vertical pipe 10 is opened due to the hinge fastening.

또한 상단의 간격이 벌어지는 반면 수직파이프(10)의 하단에 결합되어지고 교각상단(2) 끝단에 결착되어진 걸림지지대(50)는 더욱더 큰힘으로 교각상단(2)과 밀착하게 된다.In addition, while the gap between the upper end is coupled to the lower end of the vertical pipe (10) and is coupled to the end of the pier upper end (2), the engaging support 50 is in close contact with the pier upper end (2) with even greater force.

그리고 상기 제2 길이조절너트(42)를 하단고정바(41)과 하단 이동바(43)가 당겨지도록 회동시키게 되면 수평파이프(20)가 결합된 끼움대(11)을 중심으로 수직파이프(10)와 걸림지지대(50)는 더욱더 큰 결착력으로 교각상단(2)과 밀착고정되게 되는 것이다.When the second length adjusting nut 42 is rotated to pull the lower fixing bar 41 and the lower moving bar 43, the vertical pipe 10 is centered around the fitting table 11 to which the horizontal pipe 20 is coupled. ) And the locking support 50 is to be fixed in close contact with the top of the pier 2 with a greater binding force.

상기와 같은 작용으로 도 5에 도시된 바와 같이 교각상단(2)에 밀착시켜 작업자의 고소작업시 추락을 방지하게 되는 것이다.By the same action as shown in Figure 5 will be in close contact with the pier upper end (2) to prevent the fall during the operator's height.

또한 도 6은 안전망(201)을 보조파이프(200)에 고정하여 상기 보조파이프(200)를 상하단 이동바(33,43)와 체결수단(도면번호 미도시 함.)을 이용하여 고정후 안전난간대(60)과 안전망(201)을 2중으로 설치하여 작업자 추락 및 공구 또는 기자재등이 추락하는 것을 방지하는 것이다.6 is a safety handrail after fixing the safety net 201 to the auxiliary pipe 200 by fixing the auxiliary pipe 200 by using upper and lower moving bars 33 and 43 and fastening means (not shown). 60 and the safety net 201 is installed in two to prevent the fall of the operator and the falling of tools or equipment.

이상에서와 같이 본 발명은 제1 길이조절너트를 회동시켜 길이신장파이프가 밀려나도록 하여 수직파이프의 상단의 간격은 외측으로 벌어지고, 제2 길이조절너트를 회동시켜 길이축소파이프가 당겨지도록 하여 수직파이프의 하단의 간격은 내측으로 좁혀지게 되어 걸림지지대가 교각상단에 더욱더 견고하게 고정되는 효과가 있다.As described above, the present invention rotates the first length adjusting nut so that the length extension pipe is pushed out so that the gap of the upper end of the vertical pipe is opened to the outside, and the length reducing pipe is pulled out by rotating the second length adjusting nut. The lower end of the pipe is narrowed inwardly, so that the locking support is more firmly fixed to the upper end of the piers.
