Hollow Steel Planks Plank I New Building Material Hollow steel planks are arc welded together together together to to- gether to form a new type of flooring which has been developed Homes apartments office buildings and even factories can adopt this kind of con conS It is expected to speed up building reduce costs and prevent the waste of floor space Each so-called so steel plank is made up of four shaped keystone-shaped ducts hence the name keystone beam flooring floor floor- ing lag for lor the new development When a number of these planks arc are welded together they make a heavily ribbed flooring which is exceptionally strong because of its corrugated effect Besides being beme incombustible and firc fire safe safe this floor slab is exceptionally exception ally adaptable to various types of fin fm Concrete fill may be applied directly to the surface Ceilings can be suspended from the underside of the flooring as can steam or water pipes Plumbing wiring and various other services are easily installed The new type of flooring is seen as asa asa asa a boon to skyscraper construction because because be be- cause of the great reduction in weight it effects Its keystone shaped arch-shaped hollow steel slabs which take the place of masonry types of floors can be handled as readily as heavy wood planking The slabs are about four lour and one- one half inches thick and 24 inches wid wide They are arc made as long as 12 feet 5 inches at present The readily accessible accessible accessible sible ducts or cells greatly facilitate the initial Installation of electric wiring wiring wiring ing as well as subsequent changes in wiring systems This flexibility minimizes electrical obsolescence
