Safety requirements for high-altitude cleaning of external walls

There are many high-rise buildings in this city. In order to be more beautiful and transparent, most of the exterior walls of many high-rise buildings are equipped with glass exterior walls. If these glass exterior walls pass by, it is easier to accumulate dust or stains. So, what are the safety requirements for high-altitude cleaning of external walls? Next, I will bring you an introduction about the high-altitude cleaning of external walls. Let's have a look.

I. Safety Requirements for Exterior Wall High-altitude Cleaning

1. High-rise external wall engineering includes: high-rise external wall cleaning, high-rise glass curtain wall cleaning, high-rise external wall painting and high-altitude external wall advertising installation. Because of the danger and complexity of high-rise external wall engineering, this work is quite scientific and professional. The construction personnel of professional cleaning service companies have received professional training and have a lot of experience in aerial work. Most aerial work will use hanging plates for aerial work: hanging rope (aerial rope, scientific name nylon rope, diameter 18mm, tensile force of 240,000 Newton, 2 tons and a half). Hanging board (made of gray wood). Wire rope (diameter10mm). U-shaped crab clasp (steel).

2. Exterior wall cleaning personnel must undergo professional training and obtain the qualification certificate for exterior wall cleaning before they can use it.

3. Before going to work, you must carefully check the mechanical equipment, appliances, ropes, seat plates, locks and safety without damage, to ensure good mechanical performance, and all kinds of equipment can be put into use normally.

4. The operating rope and the safety rope must be tied to two solid fixed points respectively, and tied well. The edge should be filled with soft objects to prevent the rope from being worn and damaged. The lower end of the rope must touch the ground. It can also be a temporary safety rope.

Construction personnel must wear work clothes and safety helmets before going to work. Before work, fasten the safety belt, then install the safety lock (on the safety rope), and then fix the seat plate shackle (operating rope) before lifting.

6. When the rope falls, the person in charge of the construction should command at the scene and the construction personnel should help each other.

7. Auxiliary equipment should be fastened during operation. In order to prevent people from falling, it is forbidden to laugh and carry other irrelevant items.

8. Supervisors and construction personnel shall observe the tightness of operating ropes, safety ropes, twisted ropes and ropes at any time, report the problems in time and eliminate them in time.

Second, the method of cleaning the glass surface of the external wall at high altitude

1. The procedure for construction personnel to hang and clean the surface of glass decorative materials at high altitude is as follows: soak the wiping cloth in the washing liquid in the bucket, and use the wiping glass decorative materials with the surface soaked in the washing liquid. When smearing, be careful not to splash sewage on the surface of other decorative materials. When wiping the rag, in addition to scraping the decorative surface of the glass, it is also necessary to prevent the surface of other decorative materials from being polluted again, which is also the difficulty in maintaining the decorative surface of the exterior wall glass.

2. Wipe off the sewage flowing into the gap between silicone sealants and the structure. Otherwise, sewage will seep into the scraped glass surface again, leading to re-pollution. Acid can't be used to scrape glass. If the glass is cloudy after scraping, please dry it with a cotton towel. It is not easy to produce ash after scraping the glass with water, but it is easy to produce ash after cleaning with detergent.

The above is the introduction we brought to you about the high-altitude cleaning of external walls.
