Utilizing a unit such as shown in Figure 3, it will
readily be appreciated that a frame made up
as described with angles IO meeting at the cor
ners, as shown in Figure 1, may be set upon a
pianiform surface, and ?lled with a Portland
cement concrete aggregate of suitable kind, so

the junction of the ?anges of the angles a body 45 that the concrete will penetrate through the open
mesh material to the supporting surfaces, where

There is illustrated in Figure 1 a portion of
a unit structural member suitable for various
uses, and which may represent one corner of a

and the concrete may be introduced until its top
surface lies flush with the upper edges of the
angles H5, as will be appreciated. The slabs cast
in this manner will thus be reinforced by the
open mesh material, while its edge portions are
protected against chipping by the edge portions of
of the angles, and the screen material being ex

The screen material may be extended from the
inner side of this angle, substantially in the rela
tion shown in Figure 3, if preferred, and may
extend in various other directions, as shown in
the succeeding views, Figures 4, 5, '7 and following.
The angle l5 may be formed in various ways,
being adapted to be assembled from two ?at
strips or ribbons of materials brought together
at the proper angle as shown in Figures 2 and 3,
and following, where it may be a stock L-angle

open=mesh or sheet material, as will be described
more in, detail hereinafter.
In producing the
article of Figures 1 and 2, the respective strips
intended to form the. ?anges l2, are brought into
position as shown in Figure 2, after insertion of
an edge portion of‘ the screen material ll there

In Figure 4, the manner of attaching the screen
with relation to the ?anges of an angle is illus

the inner side of one of the ?anges with its ?rst
portions projected outwardly past the abutting
edge of the opposite ?ange, while a weld I 5 is
,- built up at one side of the angle around the
projected edge portion of the screen material II.
In Figure 5 the screen material is shown in the
same plane with respect to the angle, as in Fig
ure 4, but instead of being laid against the inner
side of the bottom ?ange lZ-A, and extended
away from the angle beside that ?ange, the
screen material is located outwardly of the an

angle di?ers from the arrangement of Figures 2
and 3 in that in Figures 2 and 3 the ?anges of

vertex of the angles, while in Figures 4 and 5, the
upper ?ange l2’ shown is butted against the in

the screen material inserted between the two.

its rapid dissipation, are gained in the last de

In Figure 13, there is shown the manner of
forming the stiliening member in one piece, this
consisting of strip material having opposite, edge
portions bent on a longitudinal medial line of
the piece so as to dispose the edge portions at
right angles to each other, the junction material
of the strip at its central part being struck out
at intervals to form opposed tongues 36 will

terial is then applied within the angle, substan
tially as at 16, in Figure 5, securing the two pieces
24 and 25 together, and securing the material H :
to the assembled angle.
In Figure 9, both strips 25 are notched in the
manner shown in Figure 8, and instead of one
of the strips being butted against the side of the
other, they are both disposed at an angle to the
plane of the material II and the weld is then
formed substantially as shown in Figure 2.
In Figure 10, each ?ange 29 of the sti?’ening
member orangle is shown as having extreme
edge portions pressed alternately in opposite di
number of alternated o?set ?at portions 40, and
inwardly curved sections 4|, so that when two'
strips are brought together with the inwardly
curved portions opposed to each other, the latter
may contact, and form elongated slots 42 between
the oppositely disposed ?at portions 40. In these
slots the wire intersections of the screen ma.
terial H may be respectively inserted and se
cured as before indicated.
,
From the foregoing, it will be seen that the
degree of angular relation of the two bisected
strips may be subject to considerable variations
for desired purposes, and that it is a general
advantage of welded construction that great
freedom of design is at disposal, and in the
present case, the angular degree may be dis
50 posed in such way as to obtain greater rigidity
rections, so that when brought together in proper
