Hi Folks,
Just thought I would see what the gurus had to say about how to concrete steel posts or brackets into place.
I have about 30 post holes dug (450dia and various depths) which will house mostly 75x75 steel posts as well as some saddle/stirrup brackets and I wanted to know the best way to set these in the concrete, at level and in line etc.? I was going to use a concrete pump for the pour (so time is a factor) and what I was planning to do was actually bolt the posts and brackets onto the bearers and posts and then brace these timbers into position so the posts/brackets are suspended in the hole which I am hoping will allow me to easily poor the concrete and ensure everything was in line and level (assuming they were braced well enough that the concrete won’t move anything:) ).
How do most people do this and what was the best way?
Another idea was to setup some profiles at respective levels and use intersecting string lines to show post/bracket positions and then just hold the post/bracket in place as the concrete is poured which I assume (maybe:confused: ) is how it is normally done.
I guess thinking about how I was going to do it there could be issues bracing the timbers into position as well as the bearers could restrict or hamper the concrete pump pouring (but then so would string lines everywhere).
Any advice appreciated.
