How to make and install the steel structure and fire sprinkler pipe support of warehouse over 7 meters high? Welding and drilling are not allowed on the purlin, please explain in detail, thank you on your knees! Use fasteners such as hoops and clips.

Design approval is required, and the spray pipe support can not be made on the purlin of steel structure roof casually. The weight of the support, the weight of the spray pipe, the weight of water and the dynamic load when the spray pipe is put into use must be considered.

The drilling rig is fixed with screws, but before construction, it is necessary to ask the design institute whether it has considered the self-weight design of the automatic sprinkler system. If not, it needs to be calculated and the load can meet the requirements before construction.

Precautions for installation of fire sprinkler pipe rack:

(1) When installing pipe supports and hangers, the construction personnel should adhere to the principle of "no wall support, stable corners, equal parts in the middle, and no more than the maximum value". If multiple pipes are laid on the same support, the minimum distance between supports shall be taken as the distance between all other supports.

Ensure that the installed bracket can meet the requirements of self-weight and medium weight of any pipeline arranged on the bracket.

(2) When installing supports and hangers, for pipelines with different functions, it is necessary to set a fixed bracket at the end of the pipeline to fix the pipeline to ensure the normal operation of the pipeline.

For example, in the pipeline 300mm to 750mm in front of the sprinkler at the end of the fire sprinkler system, a fixed anti-shake bracket must be set to avoid the sprinkler from shaking during operation. Only by using these fixing brackets to fix the pipeline can we ensure that the pipeline will not be affected by vibration, deformation and other factors during use.

(3) The support on the horizontal main pipe shall ensure its uniform stress, and it is forbidden for individual supports to be suspended or the pipeline to be deformed.

(4) No bracket shall be installed at the weld of pipeline connection. Support installation should be staggered by 50-200mm.

(5) The pier bearing of buried pipeline must be set on a solid soil layer, and the loose soil layer must be compacted and padded. Brick piers need to be built with cement mortar to ensure the integrity and firmness of brick piers.

(6) Do not install expansion bolts on lightweight walls and perforated bricks. Expansion bolts shall be installed on load-bearing structures (concrete structures).

(7) The setting of vertical pipe supports is clearly stipulated in relevant national codes. For steel pipes with a height less than 5m, the support is 1. 5m~ 1。 Each floor should be 8m, and the supporting height of the same building should be consistent.

For plastic pipes with a height less than 5 meters, two supports are required for each layer. For steel pipes with a height of more than 5m, two supports are required for each floor. The number of supports for hard plastic pipes should be increased according to the actual situation of the project, and the elevation of each support should be consistent.

(8) When installing PP- R, PE and UPVC plastic pipes, workers need to use special plastic hoops to support and hang them in strict accordance with relevant regulations. If the hanger is made of angle steel and flat iron, workers need to separate the pipeline from the bracket with rubber plates to avoid damaging the surface of the plastic pipe during the process of fixing the hanger.
