is shown in (e). In both (d) and (e), the gusset is made of 

 cinder concrete, as it is cheaper and lighter than stone 

 concrete and is not required to carry a heavy load. 



In (f) is shown the method of reinforcing a cornice that 

 has a heavy overhang. This construction requires special 

 care, as the cornice may be very top heavy. 



BRICK FACING AND TERRA-COTTA STRING- 

 COURSES 



The method of tying a brick facing to a concrete pier by 

 means of copper ties is illustrated 

 in Fig. 4. The ties, which consist 

 of strips of copper about fa in. 

 thick, | in. wide, and 7 in. long, 

 are placed every seventh joint. 

 These ties are spaced about 2 ft. 

 apart horizontally, and are embed- 

 ded in the concrete work to a 

 depth of about 4 in., which gives 

 them, when a f- or f-in. space is left 

 between the facing and the concrete, 

 a surface about 2\ in. long in the 

 bricks. It is customary in arran- 

 ging the brick facing to allow about 

 5 in. for the width of the brick, 

 and the space back of the brick is FIQ. 4 



usually flushed in with mortar as the bricks are laid 



FASTENINGS IN CONCRETE 



There are numerous devices intended to be embedded in 

 the concrete work for the purpose of holding T-headed or tap 

 bolts in a secure manner. These necessarily must be arranged 

 in the forms before the concrete is poured. Ordinarily, these 

 sockets should be tapped out for f -in. bolts, but where heavy 

 machinery or hoisting apparatus is to be employed, it will be 

 better to use J-in. bolts. Sockets should be provided near the 

 end bearings of each beam and girder, and intermediately, 

 not farther apart than 4 to o ft.
