SYSTEM FOR. CONCRETE CONSTRUGTIONS
George I. Rerick, St. Petersburg, Fla.
Application February 24, 1936, Serial No. 65,475
2 Claims. (01. 25-431)
horizontally with respect to the form. Arranged
This invention relates to mold or form ties for
the construction of Walls of concrete and similar
materials and has for the primary object the
provision of e?icient and durable ties which may
5 be readily adapted to and removed from forms
and which will form in the faces of the molded
material grooves which when ?lled or pointed
up provide to the wall the appearance of being
constructed from bricks, blocks or similar de
10 vices.
With these and other objects in view, this in
vention consists in certain novel features of
construction, combination and arrangement of
parts to be hereinafter more fully described and
15 claimed.
For a complete understanding of my inven
tion, reference is to be had to the following
description and accompanying drawing, in which
Figure 1 is a fragmentary front elevation
20 showing a partially constructed wall with the
form applied thereto and equipped with my in
vention.
Figure 2 is a sectional view taken on the line
2-—2 of Figure 1 showing a tie and shield therefor
25 and groove-forming element.
Figure 3 is a perspective View showing one of
the groove-forming elements.
Figure 4 is a perspective view showing another
groove-forming element.

Figure 5 is a perspective view illustrating a
supporting block.
Figure 6 is a fragmentary sectional view show
ing a modi?ed form of tie.
Figure 7 is a fragmentary sectional view show
35 ing the modi?ed form of tie connected to one of
the groove-forming elements.
Referring in detail to the drawing, the numeral.
l indicates a sectional mold or form designed for
molding concrete or similar material into wall
40 formation. The inner and outer walls of the
form are held assembled by removable ties 3.
Each tie includes a stem 4 with a head 5 at one
end and a slot 6 adjacent the opposite end. A
removable head ‘I is applied to the last-named
45 end of the stem and retained thereon by a wedge
8 extending through the slot. A tie of the char
acter described is readily adaptable to the form.
A sleeve 9 is placed about the stem 4 and has
cup-shaped ends in. Also mounted on the stem
50 4 are groove-forming elements H each of sub
stantially U-shape in end view and provided with
angularly disposed flanges H2. The groove-form
ing elements I I are apertured to receive the stems
4 and seat in the cup-shaped ends ll] of the sleeve
55 and lie between the sections of the form and
between the groove-forming elements it and at
spaced intervals are groove-forming elements it
each of substantially U-shape in end view and
equipped with angularly disposed ?anges M. 5
After the assembling of the form with my in
vention adapted thereto concrete or similar mate
rial is poured into the form and to prevent any
danger of the groove-forming elements collapsing
under the weight of the sections of the form a.
series of blocks or wedges l5 are provided. These
blocks at spaced intervals are positioned within
the groove-forming elements, as shown in Figure
1. After the setting of the concrete or similar
material, the groove-forming elements are re 15
moved along with the ties 3, leaving the sleeves
9 and their cup ends l0 embedded in the concrete.
The sections of the mold are then removed leav
ing the molded material in opposite faces thereof
with a series of grooves.
These grooves are 20
pointed up or ?lled with mortar giving the faces
of the wall the appearance of blocks, bricks or '
like devices.
Referring to my modi?ed form of invention,
the body portion I6 of the tie may be constructed
of a composition of material such as concrete
and has its ends cupped and also embedded there
in anchoring or tying elements H. The tie ele
ments ll may be passed through openings in the
groove-forming elements H, as shown in Figures 30
6 and 7.
Thus it will be seen that in this form
of the invention the groove-forming elements act
as anchoring ends for the ties.
Having described the invention, I claim:
1. A combined tie and grooving means for con
crete structures comprising a plurality of tubular
members having flared opposite ends, an elon
gated groove forming member U-shaped in cross
section disposed at each end of said tubular mem
ber, laterally projecting flanges carried by the
opposite legs of said groove forming members and
engageable against the outer surface of opposed
form members, the legs of said groove forming
members having a length sufficient to dispose the
bights thereof inwardly of the inner faces. of
said form members, the bights of said groove
forming members seating in said ?ared ends of
said tubular members, and tie members extend
ing through said tubular members and said
groove forming members and engaging against
the outer sides of said ?anges.
2. A combined tie and grooving means for con
crete structures, comprising a plurality of tubular
members having ?ared opposite ends, an elon
gated groove forming member U-shaped in cross

section disposed at each end of said tubular mem
ber, laterally projecting ?anges carried by the
opposite legs of said groove forming members and
engageable against the outer surface of opposed
form members, the legs of said groove forming
members having a length su?icient to dispose the
bights thereof inwardly of the inner faces of said
form members, the bights of said groove forming
members seating in said ?ared ends of said tubu
lar members, spaced apart tie members extend
ing through said tubular members and said
groove forming members and engaging against
the outer sides of said ?anges, and a plurality of
blocks engaging between the legs of said groove
forming member between pairs of said tie mem
bers to hold said groove forming member against
collapsing.
