Skills to be mastered during the construction of prefabricated supports and hangers

The role of prefabricated supports and hangers is very important, as they can effectively strengthen the stability of buildings, greatly weaken the damage caused by natural disasters such as earthquakes, or accelerate the progress of post earthquake reconstruction. However, the installation and construction of prefabricated supports and hangers require relatively high technology, and the entire process is also very cumbersome. There are many things to pay attention to throughout the entire process to ensure the orderly and efficient installation and construction of prefabricated supports and hangers.

During construction, prefabricated supports and hangers can deviate from pipelines and wire sleeves appropriately, but their deviation should not be too large. The construction of air ducts also allows for a certain degree of deviation, which should be less than twice the total width of the air duct.

At the vertical turning of the pipeline, the installation of prefabricated supports and hangers is necessary. When the turning angle is greater than or less than 90 °, attention should be paid to the length of the seismic bracket, which should be slightly greater than the design length. The bracket should be set on the side and vertical surface of the bracket to ensure structural stability.

In the design of prefabricated supports and hangers for water supply pipelines, the impact of water expansion and contraction caused by thermal expansion and contraction on pipe diameter and volume should be fully considered. The distance between pipelines in the vertical direction should comply with design rules, and the distance between pipelines and main roads should be adjusted appropriately.

Rigid prefabricated supports and hangers cannot be directly moved to other parts of the structure for use. Due to the special nature of rigid materials, their support structure differs greatly from general support structures, and direct use cannot provide protection.

When pipelines pass through narrow parts of a building, attention should be paid to the design and construction of settlement and displacement. The optimal angle for installing prefabricated supports and hangers is 45 °, but there may be some deviations during actual construction, which require on-site analysis and corresponding adjustments.

In the installation of single pipe door type or multi pipe door type, attention should be paid to the angle of slant support of fabricated supports and hangers. The angle should not deviate from the central symmetry line by 2.5 ° generally, or the support capacity of the support will be weakened.
