로프작업_용인 현수막 시공

로프작업_용인 현수막 시공

용인 동백지구에 있는 아파트형 공장 주차타워와 아파트 1동에 현수막을 시공했다.

기존 아파트는 쉽게 접근하여 시공할 수 있었지만, 층마다 빈 공간이 있는 주차타워의 시공은 기존의 시공과 다른 어려움이 있었다. 사진에서 보다시피 텅 빈 공간으로 바람이 계속 불었기때문에 현수막의 텐션을 쉽게 줄수 없는 현장이었다. 이런 특수한 구조의 현장은 상하로 현수막끈을 이용해 현수막을 받춰줄 지지대를 우선 시공한 후 현수막을 내려서 텐션을 잡아줘야 한다. 물론 시간은 더 걸리지만 현수막이 터지지 않기 위해선 이 작업을 확실히 해줘야한다. 

건물주 측에서는 최대한 건물이 손상되지 않게끔 시공을 했으면 하는 바램으로 피스를 사용하지 못하게 했다. 하지만 피스를 박지 않으면 도저히 텐션을 잡기가 쉽지 않았다. 건물 관리자와의 상의 끝에 좌측 부분과 양 모서리 쪽만 피스를 박고 현수막 철거시 구멍난 부분을 실리콘 보강하기로 하고 작업을 하기로 했다.

현수막 안쪽으로 현수막 끈 6개를 사용해 지지를 하고 바깥쪽으로도 6개를 지지했다. 바람이 불어도 쉽사리 터지지 않을 강도이다.  

첫번째 주차타워 시공을 마치고 다음 현장으로 이동준비 완료.

주차타워 시공현장에서 다음 아파트현장까지 네비를 찍으니 20Km가 넘게 나온다. 같은 용인이라고 해서 가깝게 생각했지만, 용인이라는 도시는 생각보다 작지 않았다. 옥상에 올라가니 오후라 그런지 바람이 불었다. 경관조명이나 구조물설치 같은 작업시 바람은 큰 방해요소이지 않지만, 이런 대형 현수막이나 야립간판 시공시에는 바람의 세기가 작업을 하는데 큰 문제의 요소이다. 그 문제가 로프맨에게 있어서는 바로 안전과 직결되므로 바람이 센 현장에서는 더욱더 안전에 신경써서 작업에 임해야한다. 

안좋은 조건에서 사진은 많이 찍지 못했지만, 안전하게 시공을 마무리해서 다행이다.

Rope Access Work_Removing Large Size Sign Channel Of Yuhan Corporation in O Chang, Korea.

Rope Access Work_Removing Large Size Sign Channel Of Yuhan Corporation in O Chang, Korea.

Have you ever seen this kind of super big sign in your life?

Well,
I had to go O-Chang early morning for requiring more technicians needs from my teammate. Its sign originally formed as neon and should be changed to LED and fixed.
Each channel of signs had 40 neons in it which are huge amount.
It's size of 6m vertically and horizontally, and more over the biggest mark has size of 9m each dimension.
Changing old neon sign to new LED is very efficient at the view point of saving energy.
Over all nation, there are a lot of work to change their lighting system as LED.
When it use neon, each transform consume 1A, it use 220W per hour, that means each channel spend 8.8kWh. so total channel including is 5, it's giant channels spending 44kWh.

Before removing the last mark hanging on the wall alone. 

Because it's so heavy weight that we had to tie the pulley supporter with several assisting ropes in order to not give damages to the wall.
and because we tighten the wall so strongly, the wall was leaned slightly. but without strong support, we couldn't assume that we can pull the mark down to the ground with 300kg double winches. If any problem happen during removing it, we had to stop using winches and conduct it using crane. 

Under construction of removing the biggest mark with 300kg double pulleyman winches.

Finally, we finished all preparations for hanging this super channel. Because this is too big and heavy, we should be careful about overload of the machines and collapsing the wall which we hang the mechines. So, slightly, little by little, he put the switch on for lifting. and it was a vital that we had to stay a side of the ropes which were connected to the other side of wall. In any case, it had possibility to tear the ropes off. Nobody wanted to fall down with it. With communicating to the people who pulled the assist bar hanging to the mark from the below, heavy monster was smoothly lifted it up and put to the ground.

As you can see the below photo, there was steel structures welded to the wall and it was also welded to back side of the mark. so it should be disconnected by grinding before we put it down. and it was so narrow space only 50 centi meter width. I hope to brace the man who done this job well. thank you!! mate

After disconnecting all channels from the wall, we chose to use crane instead of using double pulley man for safety. so 100ton crane operator came to the site and presume whether it would work or not. As he convinced it would work without any problem, we were able to disassemble all the structures which installed on the wall, arrange tools and move it from the rooftop to the ground. During we arranged, the other people from the ground were preparing to renovate the signs. they were busily dissembling the covers from the frame and tear the LED boxes.  

As I always mentioned, thank you all guys for work well done and safely today. and on behalf of leading rope access team in Korea, we promise ourselves to be aware of any unpredictable circumstances of dangers and keep ourselves safely.

Rope Access Work_Constructing Billboard Sign in Kimpo, Korea.

Rope Access Work_Constructing Billboard Sign in Kimpo, Korea.

When it was constructed, the city of Kimpo in Korea invested a plenty of money on it which was well constructed compared to other billboard signs. It was used as parcel signing so had to be replaced when it's timing for parcel expired.

Different structure, which has a electronic display on bottom of it and fluorescent lights inside, made this billboard sign hard to finish the workload. Moreover, each four side of its main display, there were about 50 cm of size of panels so it causes uncomfortable to us after removing the clamp-cover, where it's going to be hanging. 

The total size of it was 20m horizontally and 10m vertically.

Normally, when we construct these kinds of billboards sign, we pull it up on the top of the structure. however, in this place, we should pull it up by using a ladder truck due to its electronic display. That's why it cost more money, but less difficulty of constructing of billboard sign.

In order to finish workload on time, it was essential to recharge batteries before we use so that it is not going to interrupt in the middle of constructing. 

After removed four side of clamp covers, some members should go downside and uncover the downside clamp cover. It's so wide and heavy, therefore, teamwork was fundamental element.

and also, there were several indirect illuminations lighting the whole structure way down there, so should be careful to throw the removed clamp to the ground. 

In order to tighten the sign without wrinkles, there needed to tense both of bottom and above side of the sign equally. Under the situation that the distance from top roof to above clamp is about 50 cm apart, without laying down on top roof and stretching the arm just like that, it couldn't be reached. and also, the joint where the clamp screws tightened was sinked so we need to use universal joint for that point. and welding the universal joint firmly was not a choice but a essential for this extra-ordinary structure which was directly touched between the drill bit point and the sinked one.

Photograph after finished to replace the front side of sign.

Next to this place, there was river Han causing heavy wind topographically and it led us to finish the workload earlier that day afternoon. the bad situation blowing wind more harshly as time went by. Heavy wind is enemy when we're constructing these kinds of big banner. It made things slower and cause tiredness easily. So avoid from heavy wind if we can.

Several fluorescent lamps got out of its clamps when the removed sign fabrics fall to the ground. so in order to prevent an electrical problems later, we had to fix these matters before we leave.

  On the condition after tensing both side of sign fabric, we gradually begun to tighten the bottom part. All team-members became one to start tensing the order. We didn't pursued a rumpled fabric, it was necessary the long experience skills.

How To Make Rope Protective Pad

How to make Rope Protective Pad

Materials for making - Polyester Web Sling Band(10 ton, 1 ton), 3mm bolt, nut, knife, gas burner, 2mm cord, grinder. 

Today, I'm blogging how to make rope protective pad because I need it for my 100m rope.

For me, It could make it without any problem cause I have an old protective pad which one of my team members already made it. Also, I have all the tools that are needed for making it in my office so only spent money for web slings.

Taking all the seams out that are connecting with two layers of 10 ton web sling so make it one layer and then cutting it proper size of length. 

and slightly burn each side of cutted web sling so it wouldn't be taken seams out. 
and make supporting rope stand using 1 ton web sling in order to make rope fixed while working. 
Approximate size for cutting is about 20~30cm and also slightly burn each side of slings.  it gonna to be folding into two then it become about 10~15 cm.

and make three wholes in a row with red-hot drill bit for fixing on 10ton sling with bolt and nut and put the 2mm cord between folded 1ton sling. 

and put its placement from the end of 10ton sling and locate two of it. 
Remain proper width between two of them because two rope should be fixed in that space.

Connect all the bolts and nuts in the six wholes and tighten up the screws firmly until holding it. It's better to make the bolt's head going downside of the pad, because we should cut it out  the rested pieces of bolts after screwing up with grinder.

and then, we should make another rope fixing code where the other side of what we made in advance. Cut a code about 30~40cm, and make that one side is 10cm longer than another side. then longer side would be winded a rope once more than another side so it will prevent the rope to move.

Lastly, I put my name on it so it would not be mixed with other teammates', I made 4 of these, that's enough to use because every teammates have on their own. If you have more creative idea to develop this rope protector please share with me!  
Good luck!
