Day 12 Saturday, More on the job training, installing tie bolts, bracing, and final bolt down of frame.

Photo: of assembling tie bolts, with crew, showing how to install them

Photo: close up of plywood bracing panel, 2440 x 1220 x 3mm nailed off with 40x 2mm flathead nails, Clouts, as there is no clouts in Udon I used roof nails with the big head.

Top and bottom of sheet is nailed off at 50mm centres, vertical nailed at 150mm, tie rods at either end of bracing sheets, from under batten to top plate

Bracing wall with tie rods, underbatten 1 1/2 x 4 runs under the floor joist, tie rod are bolted through the underbatten, with 65 mm washers, large washers spread the load. Between the joist and under batten a nogging is used so the tie rod won't bend the underbatten up, at later stage as the timber shrinks you and tighten up the tie rods.

Photo: you can see the tie rods and on the left installed is a nogging, tierods are drilled through the nogging, on the bottom right of photo, a nogging is about to be installed. At the top of plywood 3 nogging are used to extend the ply sheet, as only 8ft sheets are available here, so a 1 ft extension is nailed on top of the main sheet.

Photo joist ties 30 x 30 x 2 mm steel angle nailed with 40mm concrets nails fitted with 8mm washers, screwed to joist

Photo: joist undertie batten, used to tie joist together, loadsharing batten 1 1/2 x 4 screwed fixed to joist, helps stop deflection of single joists when live load is applied, spreads the load across several joist, gives a more solid feel, less movement.

Joist spacing is 400mm and a 100kg load applied to centre of joist at midway of 2800mm span, the maximum deflection area, is 4mm, this is reduced to 2mm with the joist undertie, acceptable design if you want to use ceramic tiles, if applied tiles with a 2 pak glue the deflection will be less, the tiles give a stronger laminated floor, I will be sanding the ply floor

Day 13 Sunday: not much to show just cutting out the roof frame, so here is a photo of the ant capping used, a baking dish for B50

Day 14 Monday: Make roof truss, first truss set up on platform deck in jig ready to nail ply wood gussets, total 12 trusses to make







Photo , Tail end of truss with eves/ Soffit over hang of 900mm




Photo some of the complete trusses waiting to install

Day 15 Tuesday: complete truss making, cut steel brackets for truss ties steel 30x30 angles. Mark out top plate frame for brackets, Straighten frames and brace temporary.

Whow, this is so interesting.
I am sitting here with my dictionary trying to understand everything because I really want to understand everything. Not easy, but very interesting

Day 16 Wednesday No work rain day

Is the rain no problem for the wood??

Day 17 Thursday: Bit of rain is no problem, as long as the timber is wet evenly.

Today erect Roof trusses and brace, install roof battens at 600mm centers, 1 1/2 x 3 sized on face to make same thickness, fixed with 2 x 100mm nails, at 20 deg angle to give maxium grip into top cord of trusses, gives a stronger pull out force if nails are driven in at an angle, opposed to each other.

Photo: of roof trusses in place with 3 x 1/2 roof battens being fixed to trusses

Photo: Close up of trusses in place with workers installing the battens for the roof sheeting





Photo: Cutting off the tail ends of the trusses, to make same length and plumb cut, ready to take facia board that will support the gutter, facia board is sized 6 x 1 1/2, one face dressed smooth, the extra thickness of the facia board helps transfer the load of each truss tailend to the next truss either side. fixed with nails 100mm and steel angle bracket 30x30mm

Install first roof batten from this level


Installing first roof batten with nails, at later stage steel brackets will tie all the truss ends to the facia, at this stage you can see the steel brackets holding the truss to the wall frame with 2 x 14 g screws x65mm
