3 Claims.
(01. 72-4122)
This invention relates to and has for an object
thereof the provision of means for clamping and
holding the reinforcing bars of concrete struc
tures in such a manner as to form between the
bars and the concrete a bond which will be supe
rior in point of fullness, uniformity and strength.
Another object is to provide a clamp of the
character described which is adapted for splicing
or joining reinforcing bars in such a manner that
the overlapped ends thereof will be uniformly
spaced apart and thereby form a full bond be
tween the bars and the concrete at said joints.
A further object of the invention is to provide
clamping means by which reinforcing bars of
square cross section may be held in diagonal
positions, with the edges thereof in horizontal
planes and their ?at sides inclined to said planes,
whereby to prevent undesirable accumulation of
concrete on the upper surfaces of said bars dur
ing the pouring of the concrete, to eliminate at
joints or splices the horizontal intermediate and
hidden or lower surfaces» which are sometimes
not reached by the concrete where the bars are
held with their ?at sides in horizontal planes,
25 and to present for ready and intimate contact
with the concrete the entire area or surfaces of
forces. One plate is provided with bendable ears
4 adapted to be extended through apertures 5 in
the other plate, then bent back to secure the
plates together with the jaws in clamping posi~
However, any suitable means may be em
ployed for this purpose inasmuch as the main
function of this clamp is to secure together or
splice reinforcing bars B and C in such a man
ner that the overlapped ends will be uniformly,
and de?nitely spaced apart. This will provide’ 10
a full and strong bond between the concrete and
said bars due to the fact that such spacing fully
exposes the surfaces of the bars for a ready and
intimate contact with the concrete.
It is of equal importance that the clamp is 15
designed to hold bars of square cross section with
their edges in horizontal planes and their flat
sides inclined to such planes, the angular jaws 3
as particularly shown in Fig. 2 providing for such
disposition of the bars. The aforesaid angular
or edgewise disposition of. the bars, together with
the spacing thereof at the splice or joints, pro

mortar accumulation on the upper surfaces dur
ing the pouring of the concrete and assuring the
formation of a full and strong bond between the
bars and the concrete at the joints, and to also

An additional object is to provide means which, much as the edges are presented uppermost and

I have shown a preferred form of device em
bodying my improvements in the accompanying
drawing, subject to modi?cation, with the scope
of the appended claims, without departing from
the spirit thereof.
In said drawing:
Fig. 1 represents a side elevation of a reinforc
ing bar structure as set up with the clamping
45 and holding means of this invention;
Fig. 2 is an enlarged sectional view taken on
the plane of line 2-2 of Fig. 1; and
Fig. 3 is an enlarged section taken on the plane
of line 3--3 of Fig. 2.
One embodiment of the invention as shown in
detail in the accompanying drawing comprises a
clamp A consisting of complementary clamping
plates I having abutting portions 2 between their
ends, and angular jaws 3 at their ends. Each
jaw has right angularly disposed rod engaging
position of the bars is particularly advantageous
in circular reservoir walls inasmuch as the ex
posed surfaces of the bars enclosing and support
ing the inside or fluid side of the concrete is
greatly increased as against the surface provided
with a flatwise disposition of said bars.
While as here shown I have provided two
clamps A for the splice of Fig. 1, I may use one 45
or more than two clamps.
Operating conjunctively with the clamps A
are auxiliary clamps D which are engaged with
the upright reinforcing bars E and bars B and C
to aid in holding the latter in the diagonal or 50
edgewise positions. Each of the clamps D com
prises a single piece of metal bent to form a U
shaped body ‘I and spaced extensions 8 having
V shaped notches 9 therein. The body portion 1
is adapted to embrace the upright bars E as 55
particularly shown in Fig. 3, and the extensions
8 are disposed to engage the horizontal bars B
as shown in Figs. 2 and 3, the bars B and C
?tting into the notches 9 as shown in Fig. 2.
It will now be apparent that the clamps D will
hold the bars B and C in the desired edgewise
position throughout the reinforcing bar structure
and also strengthen such structure.
Attention is called to the fact that the means
of this invention not only provides for the con
crete ?owing completely around and making an
intimate contact with the reinforcing bars where
by to provide a superior bond at the splices or
joints, but will strengthen the reinforcing struc
15 ture and increase the e?ectiveness thereof in re
inforced concrete constructions.
By the terms “square cross section” or “square”
bars I mean to include all bars of ‘angular and
rectilinear cross section or wherein the bars have
20 ?at sides and de?nite or narrow edges or ridges.
It should be noted that the reference to- the dis
position of the edges of the bars in horizontal
planes is meant to include planes nearer to the
horizontal than to the vertical, as when bars
25 are inclined. In fact, the invention contemplates
holding the square bars with edges in the upper
most plane of the bars.
What I claim, is:
1. A clamp for reinforcing bars, comprising op
30 posed plates, portions between the ends of said
plates adapted to engage one another, opposed
laws at the outer ends of said plates, and means
for securing said plates together, said jaws hav
ing substantially identical right angularly dis
posed bar engaging faces arranged to hold bars of 5
square cross section in superposed overlapped re~
lation with their edges in horizontal planes and
their ?at faces inclined to said planes.
2. In reinforcing means for concrete structures,
reinforcing bars of square cross section, means 10
for joining said bars and holding end portions
thereof in overlapped and spaced relation to one
another with the edges of said bars in horizontal
planes and the flat faces of the bars inclined
to said planes, other bars perpendicular to the
?rst named bars, and members inter-engaged
with said ?rst and second named bars and having
V-shaped portions for receiving and holding the
?rst named bars in said edgewise position.
3. In reinforcing means for concrete structures,
reinforcing bars having ?at faces and narrow
edges, means for holding said bars with the edges
thereof in horizontal planes and the ?at sides in—
clined to said planes, and other bars perpen
dicular to the ?rst named bars and holding mem- "
bers having V-shaped portions for reception of
said ?rst named bars and U-shaped portions for
reception of said second named bars.
