What should be noted when installing prefabricated supports and hangers?
The installation of prefabricated supports and hangers has become a trend, so what should we pay attention to when installing prefabricated supports and hangers?.
Due to the involvement of many mechanical and electrical subsystems in prefabricated support and hanger systems, it is important to grasp the entry time node. Early entry may result in unnecessary idle work due to lack of working face, and late entry may lead to installation difficulties. Therefore, in the early stage of installation, on-site inspections should be conducted to determine the corresponding time nodes based on the overall project schedule and the progress plans of each subsystem, to ensure the construction progress..
(1) Carry out technical briefing during the installation of prefabricated supports and hangers before installation.
During the installation process of prefabricated supports and hangers, it is necessary to first provide technical briefing to the construction personnel, so that they can proficiently master the relevant technical requirements that should be followed during the installation of prefabricated supports and hangers..
1. Employees must wear safety helmets when entering the construction site..
2. Safety belts must be worn when carrying out high-altitude operations..
3. Construction personnel are strictly prohibited from working under the influence of alcohol or fatigue..
4. When using tools and wiring is required, it is necessary to follow the on-site construction management regulations and wire protection measures must be taken from the designated area. Bare connections, exposed wires, and other situations are prohibited..
5. When working in basements and dimly lit areas, it is necessary to use other lighting and ensure proper protection of the lighting power supply..
6. The installation of anti-seismic supports and hangers must be strictly in accordance with the points in the drawing. The construction personnel shall not adjust the spacing between points or reduce the points without authorization. The angle of each slant support must meet the specification requirements. The bolts used should be reliably connected with the structure to ensure that each component is fastened and reliable. When the actual on-site pipelines do not match the drawings, it is necessary to contact the manufacturer in a timely manner to conduct mechanical calculations based on the on-site pipelines, select appropriate support types, and meet the seismic stress requirements of the on-site pipelines..
7. All spare parts and profiles of products should be prefabricated in the factory and assembled according to on-site dimensions. Welding is not allowed on site..
8. On site cutting of channel steel should ensure that the cut section is vertical. After cutting, burrs should be removed using a file, and then the cut should be repaired with anti-corrosion coating. The repaired coating thickness should not be lower than the original coating thickness..
After installing each batch of prefabricated supports and hangers on the construction site, the installation personnel need to implement a three inspection system, which means that the installation personnel first need to self check, then other teams inspect, and finally the on-site personnel conduct a final inspection. For supports and hangers installed that do not meet regulatory requirements, they must be resolutely rectified to ensure the installation quality of prefabricated supports and hangers..
