Working alone at a construction site makes you "brainwash". There is no one hoping for. And help is needed. Submit, bring, hold these actions are performed by the assistant. What if you like to work "in one"? and there is no one to hold or squeeze. It is for these cases that clamps are needed.
The usual function of a clamp is to tighten objects or fix something. For example, a processed board on a workbench. Basically, they serve for this.
But if you flip the movable support, what do you think will happen? To do this, unscrew the screw, turn over the support "paw", tighten the bolt and screw again. Photo in gallery:
That is, the function of the clamp includes not only compression and fixation of objects, but also expansion.
Now I will demonstrate, using an example of installation in a PPU bath (chimney fire unit), how to use clamps.
In order to secure this structure, it must be lifted to the ceiling, fixed with your hands. This action is usually performed by a helper. And the master, meanwhile, fixes it with self-tapping screws. Usually from inside the steam room. I do not have a utility room, except for this, the task is to fix it inside the attic for the walls of the PPU.
In the photo I show the inside of the fire unit and the clamps hold it for me, how is this done? In the photo below, in the gallery, everything is very clear:
This is how the function of the clamps expands, I'm sure the information was useful to you.
