Generally speaking, I think you need to pay attention to the following points when setting up on-site:
1. The foundation should be flat and compacted, and pads and ramps should be set according to the properties of the soil. There are also appropriate drainage measures. After all, scaffolding is made of steel pipes. Long-term soaking in water will cause the steel pipes to rust, posing a major safety hazard. I have been exposed to many projects, and most of them are not very good at this point.
2. The erection of scaffolding should start from one end and proceed layer by layer to the other end. At the same time, ensure that the step length, span length, joints, and support points are in the correct position. The erection of scaffolding should comply with relevant safety standards and regulatory requirements to ensure its structural rationality and stability. During the erection process, the vertical and horizontal deviations of the poles should be corrected at any time to avoid excessive deviations.
3. Erection workers must wear safety belts and abide by safe operating procedures to ensure safe operations. This is also a problem often found when erecting scaffolding. Ordinary workers, especially veterans, often take chances and think that wearing safety belts will affect the construction. I have been exposed to several projects, and this situation basically exists. There are always one or two people who do not wear seat belts.
4. Ask about the wall-mounted parts of the scaffolding. The wall-connecting parts of the scaffolding vary according to the plan calculation book. They may be two steps and two spans, two steps and three spans, etc. The most common problem that occurs on-site is that the wall-connecting parts are missing and are not set up according to the plan requirements. Some are often missing here and some are missing there. In addition, the wall-connecting parts of the scaffolding need to be set up from the first step. If it is impossible to set up, it is necessary to set up throw supports or take other measures. This is easily overlooked on-site.
5. The erection materials of this scaffolding should meet the design requirements, and unqualified fasteners, steel pipes, and other materials must not be used. Although scaffolding materials need to be inspected when entering the site, most inspections are not careful enough. If the steel pipe is found to be deformed or cracked during later erection, it needs to be replaced in time.
6. When the scaffold reaches a certain height and width, scissor supports need to be installed. The scissor brace setup starts at the bottom. Generally, the width of each scissor brace should not be less than 4 spans, and should not be less than 6m. The inclination angle between the diagonal pole and the ground should be between 45° and 60°.
7. Issues with the installation of safety nets, steel fences, and skirting boards for scaffolding. The main reason is how many items of safety nets now have flame retardant properties and fire protection limits. In terms of flame retardant performance, it is required that the afterburning and smoldering time of the flame retardant safety net shall not exceed 4 seconds.
