How to install temporary roof supports. Bring in the temporary beams and install them in place. Attaching the two with bolts every foot or two 50 cm. The temporary support that you use will need to have a firm footing in order to hold up the weight. These pieces act as the bases that hold the legs of the support beams.

For a perpendicular support you should use square pieces of 3 4 inch plywood or other scraps of wood that are at least 10 inches wide. Use several bolts at the ends of the wider lumber 7x2. Once it is plumb mark the position on the porch roof. Continue installing porch roof supports.

Vertical shoring against the top chord of the joist is most certainly the least expensive choice. If the ground area is hard and difficult to penetrate then you can go for an alternate solution. I would never install temporary shoring of open web joists on their bottom chord. Make sure that the beams support the roof well and are not left loose or wobbling.

Stand a post up in the bracket and hold a level on its side. The ideal height of such beams should be 2 10 foot longer than the distance between the roof and the ground. Place the wood on the floor or ground and hold in place with small screws. If you have space and there s any structure left near the ends the easiest way is to not replace the existing rafters and joists but to sister a second board on the side of each.

Use 2 inch carriage bolts to secure the posts to the mounting brackets. I did not interpret your question as whether to support the open web joist on their top or bottom chord.
