The issue of the extension length of foundation bolts
Thread Content
Why do the foundation bolts with covers on the skirt base need to extend above the cover plate? Can’t they just extend above the base plate? Look at the parts of the formula that are not affected; if it’s a single-ring plate, the calculation formula for the foot bolts is the same
How can nuts be fitted if only the base plate is extended? And the stress capacity isn’t good either; just the bottom plate won’t work
Reply to 2# SuperFree2316: There is usually enough space between the upper plate and the lower plate to fit nuts. The key question is why it doesn’t work under stress? Can’t single-ring plates be used as well?
Then why do you still need the cover plate??
Reply to 4# hnstar18: The upper cover is used to enhance the bottom plate’s resistance to deformation and reduce its thickness
