Distance between the steps of a ladder-style tripod support
Thread Content
I didn’t know how to calculate it, so I asked others; no one had actually done the calculation carefully, and everyone had been assuming that the height difference was ≤2m. So, given that the 50341 spiral staircase can withstand a concentrated load of 5KN, what should be the maximum distance for the tripod?
It’s usually around 2 meters apart. For the angle steel, it’s generally 63-75 millimeters in size. So, what’s the volume in cubic units?
Experience suggests a spacing of around 2 meters; generally, it’s less than 2 meters. To determine the exact value, modeling is required – the load on the spiral staircase is distributed evenly, with an additional 5 kN of concentrated load. Then, the shear stress and bending moment of the supports can be calculated. If you’re asking about the maximum distance, I personally think 3 meters is no problem.
For 16-year storage tanks, I’ve never seen triangular supports placed every 3 meters in the construction drawings; haha
I can’t calculate it. If it fails, will it be due to a separation at the weld on the tank wall? Is it the deformation of the angle steel itself? Is there a welding coefficient for this type of welding?
Does this have a lot to do with the size of the jar? If it’s an infinitely large tank, it’s equivalent to a 45° inclined ladder, which would be even safer
