Day 8 Sunday: Install bearers and joist, went for a combanation of timber and steel,Bearers were the same price in either timber or steel, allowing for the painting, timber a bit easy to work with,
Steel joist were 100x 40 x 2 mm at B45 mt , timber was B75 a mt 100x 38mm total of 180mt x B30 a saving of B5400 using steel, but approx 5 hours extra work for the crew to screw the flooring dow, compared to using nails on a timber joist
Photo of bearers and joist, bearers were fixed down to post with 2 x 12mm bolts and large 75mm washers to on the timber to achive a tie down rating of 60mt/s.
joist double up under internal bracing walls , no internal wall is load bearing, roof load gets transfered to out external walls, on all joist across the 3 bearers, fixed down with 30 x 30 x 1.5mm steel angle, nailed with 40mmx 2.5 concrete nails with load spreading washers nailed into bearer, no hard nail clouts available in thailand, so made do with that system, tie down bracket fixed to joist with 20 x 2.5 wafer self drilling screws x 2 per joist, in photo you can see 1 of the brackets, and the 2 screws sticking through the other joist, more detail later with close up of connections.
Stump has ant capping, not much standard material available for such things here, so the capping is baking dish aluminium B50 from Macro. This capping helps stop white ants , and general ants, the dont like travelling up around the capping, and you can put oil/ chemical on the top side of capping to stop the bugs, the system is designed to slow down the access of the crawling insects, based on a monthly visual inspection, if done right as is shown, you only need to look as you walk past the stumps to see if there are signs of any dirt tracks up the post, the capping adds a little more divation for the creaters to crawl up and over
Now we got the wind loading for the bearers and joist, the ants under control, on to the flooring
