MISCELLANEOUS FLOORS 295 



The safe loads in addition to the weight of the floor as given in 

 the manufacturer's catalog are given in the following table : 



SAFE LOADS FOR "BUCKEYE" FIREPROOF FLOOR. 



Multiplex Steel Floor. The steel flooring shown in (b) Fig. 144, 

 is manufactured by the Berger Mfg. Co., Canton, Ohio. This floor is 

 made with corrugations from 2, to 4 inches deep and of Nos. 16, 18, 20 

 and 24 gage steel. The triangles are filled with concrete and the floor 

 is given a cement finish, or is covered with a wooden wearing surface. 

 Tables of safe loads for Multiplex Steel Floor are given in the manu- 

 facturer's catalog, and are larger than for the "Buckeye" Flooring for 

 the same span. 



Ferroinclave. Ferroinclave is fully described in Chapter XIX. 

 It has been used by the Brown Hoisting Company for floors as well as 

 for roofing and siding. It should make a very satisfactory flooring 

 where light loads are to be carried. 



Corrugated Flooring. Corrugated flooring or trough plates 

 shown in (a) and (b) Fig. 145, are used for fireproof floors where ex- 

 tra heavy loads are to be carried in mill buildings, in train sheds and 

 for bridge floors. The troughs are filled with concrete, which is given 

 a finishing coat of cement and sand or is covered with a plank floor; 

 the planks being laid directly on the plates or spiked to spiking pieces 

 imbedded in the filling. The details, weights and safe loads for corrug- 

 ated plates are given in Pencoyd Iron Works' handbook, in Carnegie 

 Steel Company's handbook, and in Trautwine's Pocket-book. Details 

 of corrugated plates are also given in the American Bridge Company's 

 "Standards for Structural Details."
