Rebar splicing a key problem area with our Philippine house building project. Philippine buildings generally consist of steel reinforced concrete columns or posts supporting steel reinforced concrete beams with the spaces filled in with fairly weak concrete block forming the walls.  The reinforcing steel is referred to as “deformed rebar”. Ours is a one-story house, so a single standard six meter long rebar (about 20 feet) can extend from the footer (1.2 M deep) to the topmost roof beam without splicing.  That’s a good thing.  Our columns used 12mm diameter rebar. All …

Splicing error in roof beam rebar Our Philippine house building project: concrete roof beams.  This photo shows the 16mm rebar framework for the concrete roof beam which is supported by the columns and in turn will carry the considerable weight of the roof structure. For that see http://goiloilo.com/our-house-project-welding/ . A visit by our engineer confirmed a problem with the arrangement of the rebar in the beam.  Rebar comes in six meter lengths.  As shown in the photo, the workers spiced all the rebar in the center of the span.  The engineer directed that splices be staggered with no splices at mid-span in the bottom rebar and no splices at the support columns in the top of the beam. Everything you see above will have to be taken down and redone.  Our plans lacked a rebar splicing plan.  This has caused endless required corrections…

We are building a house on Panay Island in the Philippines.  We’ve documented our project with photos, text and building cost reports.  Here’s the index to our posts: A forest of bamboo scaffolding 3-10-2010 An index to posts about our Philippine house building project.
