I-beams, in simple terms, are essentially steel I-beams that are used as temporary supports in welding structures； A mouse hole is the over-welding hole in welding ； Dog bone-shaped shock absorbers that help combat fatigue ； Where’s the cat walk? Is there anyone who knows the subject and can send a picture? ;P The picture below shows rat holes and dog bones
There’s also Monkey Fist, which is just a knot.
Shark clip, Shark Jaw – used for gripping and pulling anchor chains.
What is monkey fist used for? Let’s do some popularization
This is easy to understand; there are also cylindrical ones, which I’ve seen when taking a boat, haha
Hold onto the rope, in case it comes loose. After installation at sea, some pins, blind flanges, and the like need to be removed and tied up with a rope; the ROV or diver holds onto the rope, which has a knot to prevent it from slipping away into the sea and causing pollution.

It has nothing to do with I-beams. Concrete poured crane beams, roof truss beams, and structural beams for floors can also be installed. Generally, brackets are attached to columns; oh, they can also be found on the columns of steel structure frameworks – all of these are called brackets.
