FLOOR JOISTS. STUDDING. BRIDGING. HTQ. 



To have all joists and studs sized or made even 

 in width is desirable. Where practicable to have mr.terirl 

 Sized, do so. If impracticable, rough material mr.y be 

 used. To size it by hand may be necessary. Joists should 

 be of selected sticks, straight grain and free from all 

 knots larger than 1 inch in diameter; 1st choice being 

 Douglas fit, 2nd choice white fir, 3rd choice yellow pine, 

 Studding, headers, trimmers, plates, etc., may be of any 

 straight grain material free from loose knots and knots 

 which materially weaken the stick. Lay floor joists 

 directly upon the sills. Where two joists form the span 

 use the lap joint; in all cases place the bow of the joists 

 up. Place solid 2" x 6" bridging at the ends of each 

 joist. If spen exceeds 12 feet, place 2" x 4" cross bridg- 

 ing in the co;.ter. See Cut No. B.M.-9. 



Lay the floor first. Then, place floor plates 

 for both ins:' e ina outside walls on top of it. 



KiOre corner stiids of 2" x 4" scantling spiked 

 together (s?e Plan). The corner posts should be assembled 

 before Instilling them. Place studs on top of floor 

 platea. Double the top plates. In splicing, lap them 

 at least 4 feet and arrange to have the ends of the lap 

 fall over studs. 



Double head-ers over window openings and door open- 

 ings. If shingle siding is used, double trimmers also. 



Place girts of 2" x 4" scantling horizontally 

 in all outside walls midway between the top and bottom 

 pi a tea. 



Place girts of the same size as the studding for 

 backing for the outside skirt parts (see Plan). 



At elevations of 3000 feet and over brace the 

 studs with 1" x 6" piece cut into the studs, to sudh a depth 

 that the outside faces of the braces are flush with the out- 

 side face of the studs. See Cut No. B.I.!. -9.
