How to lay your bearer beams
Set your bearer beams out beside your pier posts and determine how best they can be arranged, making sure bearers are joined over piers. Site the bearer edge to check for bows and set bearer with any bows uppermost. As there is only two bolt holes in the pier, basic carpentry joints need to be cut in the bearer ends to allow each to connect to the pier. Here are a couple of examples of joints which can be easily cut with a speed saw and sharp chisel.
Seal the joints and end grains, as well as where the bearer sits on the pier, with wood sealant or paint. Clamp the bearer to the pier housing, drill bolt holes, thread through galvanized bolts and use large square washers and gal nuts. Tighten with a ring spanner. Remember 'tight is tight, too tight is cracked'. Come back in 24 hours and nip them up if required. Trim off bearer ends if required and seal. Use an electric plane to eliminate any bows that might impact on your floor joists.
The next step is laying the wooden joists. Our floor joist setup page sets out easy to follow guidelines for completing wooden floor joist layouts. Our floor sheeting page guides you through laying a perfect floor for your new kit home.
