Claims29
A support apparatus for a construction mast comprising:
- a truss for fixed connection to a vertical surface, the truss including
- a top frame defining a first aperture for receiving a construction mast;
- a bottom frame defining a second aperture for receiving the construction mast;
- vertical members connecting the top frame and the bottom frame;
- and
- lacing members extending between the vertical members;
- and
- a top adjustable mount assembly mounted to the top frame, wherein the top adjustable mount assembly includes a plurality of mast engaging elements positioned at spaced locations on the top frame and adjustable with respect to the top frame to extend radially inward for securing the construction mast.
