FORM WORK 



One of the best methods of constructing wall forms is to 

 use concrete separators. The separator known as the 



FIG. 14 



McCarty separator, used in constructing the form work, is 

 illustrated in Fig. 11. The separator c is cast previous to 



the construction of 

 the forms. 



Clamping De- 

 vices and Plank 

 Holders for Wall 

 Forms. Many de- 

 vices that aid in 

 the construction of 

 concrete walls have 

 been invented. One 

 of the most useful 

 of these devices is 

 the Sullivan 

 pressed-steel plank 

 holder, various 

 forms of which are 

 shown in Fig. 12. 

 These holders are 

 formed from an 

 iron plate by shear- 

 ing and bending it 

 so as to form clips. 

 The application

of this type of plank holder is illustrated in Fig. 13.
