Selection method of fasteners (bolt, rivets, other fastening parts) 1: For structure, case ..... Apply axial force
Selection method of fasteners (bolt, rivets, other fastening parts) 1: For structure, case ..... Apply axial force
Importance of axial force (tightening force), explanation 1 ○ In the case of tensile load to peel off the plate
If there is no axial force (tightening force to the member), separation occurs and it is easy to break
Importance of axial force (tightening force), explanation 2 ○ In the case of a load that shakes the plates in the plate shear direction
If there is no / less axial force (tightening force to the member), it may be broken and it may break easily
Important things to consider when considering joints:
Notes on choosing fasteners (bolts, rivets, blinds, blinds, rivets, etc.):
How to use in the shear direction: Description 3 ○ When there is a load in the lateral direction of the plate
Depending on the conditions, there may be repetitions and parts and bolts may be fragile.
Notes on choosing fasteners (bolts, rivets, blinds, blinds, rivets, etc.):
When building a structure or casing, pay attention to the presence of the axial force (tightening force) and the function of filling holes (hole fill).
Even if the axial force is early, it is judged by design whether it is a mechanism that holds the axial force for many years. Is it necessary to check the axial force?
Also with regard to slack, is it in a structure that does not slacken? Use what you know.
Please confirm it by the Junkers test (check the change of axial force by time and cycle) or the NAS 3350 test (sag is a visual confirmation method).
Rivets are easy and easy to use, so they can easily be used later.
In particular, select blinds and rivets carefully. .
