Simplex Sidewalk Light construction
embodies all the advantages of the regular reinforced
concrete type but omits all of its objectionable features.
In building the Simplex Slabs, the
under half is made in our factory. This is one of the best
concrete, properly proportioned (one part Portland cement
to two parts sharp sand), moulded around the lower half of
the steel I bars. Through the mass, piercing and
tieing together the steel I bars are twisted square
rods 5/16 inch thick. A Thus the lower half of the slab
of reinforced concrete is complete when it leaves the
factory. When on the job, this slab is put in position, the
glass set in the opening and the top half of usual cement
finish put on. Any good cement finisher can install the
Simplex.
As in the Paschall, the head of
the I bar locks the upper half of the concrete in
place so that it rigidly and securely holds the glass in
its place. |
Detail of Construction of 3-Way Simplex Slab
Because of the two layers of
concrete, each reinforced by the same I bars, the
strength of the slabs is increased without increasing
the weight. The I bars, the strength of the slabs
is increased without increasing the weight. The I
bars (1½ inch) extend longitudinally through the
slab so that the ends of the bars are on the bearings at
each end when set in position, and, as in the Paschall,
construction, the strength of the bars is so much greater
than the usual reinforcing rods that no supports on the
sides of the slab are needed for the average span.
