When working with equipment that spans multiple floors, how can one determine the dimensions of the openings needed in those floors based on the size of the equipment?
Thread Content
The equipment passes through floors, and the equipment on the floors is secured using lug-type supports. Given the dimensions of the equipment and those of the lugs, how can one determine the size of the openings in the floors? Not a lifting hole.
The ear-type supports are fixed; once the dimensions of the equipment and those of the ear supports are known, generally we make the hole size 150–200 mm larger than the diameter of the equipment (taking insulation into account)
Generally, a square hole that is 200 mm larger than the external dimensions of the equipment (including insulation)
It mainly depends on the diameter of the equipment and the location of the supports; the dimensions of any special pipe connections also need to be taken into account. For ease of installation in the future, it’s best to view the drawings in CAD to see if there will be any conflicts with the structural beams during lifting
May I ask then: is the opening size reserved for the ear seat on a concrete foundation the same as that on a steel beam? Are they all 150~200mm?
Agree with what was said on floor 2! The procedural steps during installation also need to be considered
The ear seat base plates, which bear the weight of the equipment, must all be located on the beams
7# jlchina In fact, the locations where ear mounts can be placed are: on steel beams, concrete foundations, and brick foundations
Generally, we leave 300 mm for the outer diameter of the equipment; actually, it is possible to lift the equipment up and then weld ear brackets onto it
