MEANS FOR ANCHORING STRUCTURAL
ELEMENTS T0 GONCRETE SUPPORTING
BODIES
Russell J. De Wees, Dallas, Tex.
Application December 2, 1935, Serial No. 52,581
2 Claims. (Cl. 72—10'1)
This invention relates to means for anchoring ceiling elements. Furthermore, even if the sheet
structural elements to concrete supporting bodies.
It has more particularly to do with improving
the means of anchorage for masonry, in outside
5 wall construction of buildings and the like, and
also for interior wall and ceiling elements, ?oors,
et cetera.
In concrete supporting body and frame struc
tures it is a common practice to embed within
the body of concrete a metal channel-formed
insert of angular shouldered cross section to func
tion as a lining and reinforcement of an under
cut continuous groove or slot in which anchoring
or tie members having counterpart or otherwise
5 formed engaging portions are received and ad—
justably supported, said anchoring or tie mem
bers being provided in or on their portions outside
of said undercut or interiorly shouldered groove
or slot with means for securing the masonry or
20 other wall or ceiling elements, and the like.
The customary procedure in applying the lin
ing inserts, which are usually formed of compar
atively thin gauge sheet metal of just sufficient
inherent rigidity to retain the shape in which
25 the device is formed under reasonably normal
conditions and handling, is to nail or otherwise
secure the device to the ordinary form board usu
ally employed in pouring and packing the con—
crete material in forming the structure, that is
30 to say, with the open side of the device disposed
against the face of the form board with the ob
ject of preventing the concrete material from
entering the interior of device.
Owing to the relatively rough character of con
35 crete construction work it is difficult to maintain
a sufficiently tight contact of the ordinary lining
insert with the face of the concrete form board
at all points throughout its length, due to the
irregularities in the surface of the board and
40 also to the distortion and deformation of the
insert in the pouring and tamping of the concrete
material, with the deleterious result that the con
crete material enters and clogs the channel de
signed to be produced, and obviously, there is in
45 curred the added expense of removing the mate
rial irom the channel after the form board is
removed, which operation requires not only time,
but care and skill. So, too, without close super
vision, there is the liability of some mechanics
to shirk the work of removing the material and
should there be an obstruction at the point where
an anchoring element is to be applied there is the
possibility that the anchoring element will be
omitted when the wall masonry element should
55? be'tied in place or in the placing of other wall or
metal channeled insert is tightened throughout
its length against the face of the concrete form
board, it sometimes happens that the side walls
of the insert are pressed inwardly to such degree
of deformation that it is di?icult or even prac
tically impossible to apply an anchoring element
in the region necessary for the tying of a masonry
element or other wall or ceiling element, as the
case may be, and to avoid which happening it
has been found necessary to make the insert of
heavier gauge sheet metal than would otherwise
be required.
The principal object of the present invention
is to overcome the disadvantages herein noted
and permit constructing the channeled metal in~
sert of relatively lighter gauge sheet metal than
heretofore used; to provide not only for prevent
ing the entrance of concrete material into the
channel but at the same time prevent collapsing
of the side walls of the insert during the pouring
of the concrete material as well as in the han
dling of the insert prior to and while it is being
nailed or otherwise attached to the concrete form
board, and particularly facilitating the cutting
of the inserts into different lengths for the work
required without liability of deforming the in
sert; and to attain certain other objects and
advantages as will hereinafter more fully appear
in the following description.

The invention consists in the novel general
provision of a ?ller member of a removable char
acter for channeled metal inserts for the pur
poses described, and in the parts and combina
tions and arrangements of parts hereinafter spec
i?ed and afterwards set forth with particularity
in the appended claims.
In the accompanying drawing forming part of

the speci?cation and illustrating practical adap
tations of the invention,—

40
structural body with a channeled lining insert
therein and showing the concrete form board as
cooperatively applied;

form of anchoring element, detached;
Figure 6 is a perspective view of a modi?ed
form of anchoring element, detached; and
Figure '7 is a fragmentary view, in cross sec
tion, showing a modi?cation of the channeled lin

ing the concrete form board,
Referring now more particularly to Figures?l
10 to 5, inclusive, of the drawing, the numeral l
designates an ordinary concrete structural body
having embedded therein a channeled sheet met
al insert 2, which latter, as shown in Figures 1, 2
and 3, is formed rectangularly, as at 3, with one
of its longer sides slotted, as at I3, and at opposite
sides of the slot provided with parallel perpen
dicular ?anges 5.
At intervals, longitudinally and at the middle
of the body portion of the insert 2, there is pro
vided a series of apertures ii for the reception of
nails, screws or other securing elements, as will
be later more fully described, said apertures
eing alined medially with respect to the slot 4
of the insert.
When the insert 2 is embedded in the concrete
body I (see Figure 2) it constitutes a lining and
reinforcement for an undercut groove or slot in
the concrete body, the preferred practical form
thereof being substantially T~shape, as shown,
30 and the preferred form of anchor element, as
shown at ‘l, in Figures 2 and 5, having a counter
part neck and head portion to ?t in said insert
2 relatively closely and with only slight looseness
to permit insertion of the anchor element edge
wise through the slot 15 to place the head portion
8 within the rectangular portion 3 of the insert 2
and the turning of the element l' until its head
portion 3 is ?atwise transversely of said rectan
gular portion 3 and its neck portion 9 is corre
spondingly positioned between the flanges 5 of
the insert 2, as shown in Figure 2.
The outer portion of the anchor element 7
which engages the masonry element, indicated at
It] in Figure 2, may be of any desired or ap
45 proved form. However, for more general pur~
poses, and as found practical, the anchor ele
ment 1 is preferably made substantially I-shape
as shown in Figures 2 and 5, that is to say, with
both end portions alike, whereby either end por
tion may be secured in the channeled lining in
sert 2 and, too, either end portion may be utilized
for tying the masonry element ill or other wall
or ceiling element in place, as the case may be,
to the concrete body i.
In Figure 6 a modification of the anchor ele
ment is shown, wherein there is a head portion
i3a connected by a neck portion 9a to a body
plate or enlargement H provided at its end with
oppositely turned lugs or ?anges i2, i3, respec
60 tively, for attachment to the masonry element
or other wall or ceiling element to be tied to the
concrete body, the head portion 8a and neck por
tion 93, obviously, ?tting the channeled lining in
ert 2 in the same manner as the portions 3 and
9 of the ?rst described anchor element 1.
Obviously, other modi?cations of the anchor
element may be made and substituted for those
herein illustrated within the purview of the pres
ent invention, the principal object of which is
to prevent the concrete material from entering
the channeled lining insert and/or the collaps
ing and deformation of the insert in the prelim
inary handling thereof as well as in its applica
tion to the concrete form board in producing the
. concrete body in which the insert is placed.
Prior to its attachment to the concrete form
board, indicated at M, in Figure l, a wooden or
other removable filler member is placed in the
slotted portion of the channeled lining insert 2.
Preferably, as shown, the ?ller member, indi
cated by the numeral [5, is made of wood and
rectangular in cross section (see Figure 4) and
?tted into the insert 2 as shown in Figure 1, said
?ller member l5 being of transverse or cross
sectional dimensions to ?t tightly between the 10
?anges 5 of the insert 2 by being forced into place
but without appreciable spreading of said ?anges
5 or causing other deformation of the insert,
and, when in place, one of the narrower sides of
the ?ller member abuts the inner face of the
body plate portion of the insert 2 and the opposite
narrower side is ?ush with the margins of the
flanges 5.
The channeled metal insert 2, with the ?ller
member l5 placed therein, is applied to the con
crete form board ill by driving nails l6 through
the apertures 5 in the body plate portion of the
insert, into and through the ?ller member l5, and
into the form board 14 (see Figure l), the aper
tures 6 being of larger diameter, respectively,
than the heads of the nails 16, whereby, when
the concrete material has been poured and the
body 2 set, and the form board is removed, the
?ller member I5 is most invariably withdrawn
from the insert 2 with the form board. However, 3O
should the ?ller member £5, for any reason stick
in the insert 2 and the form board I4 be pulled
from the nails i6 while it is being removed from
the concrete body i, the ?ller member I5 is read
ily removed afterwards from the insert 2 by ap
plying a gripping tool of some kind to the pro
truding portions of the nails 56 or by other means
applied directly to the ?ller member.
As shown in Figure '7, the channeled sheet met
al insert 2 may be modi?ed by rebending or fold
ing the metal at the bases of the ?anges 5, as at
ll, thereby producing shoulders against which a
modi?ed ?ller member We is made to abut when
placed in between said ?anges 5. In this modi
45
?cation less wood or other material is required
for the ?ller member and yet a substantial re
inforcement is provided to prevent collapsing or
deformation of the insert and it is just as eifective
in preventing entrance ofv the concrete material
into the channel of the insert as in the applica—
tion of the ?ller member 15 as shown in Figure 1.
It is noted that in this modi?cation illustrated
in Figure 7 the nail H3 is driven through the form
board 14 into the ?ller member I521. Obviously,
when the form board is withdrawn from the con
crete body in which the insert 2 is embedded, as
in Figure l, the ?ller member i53 is most invari
ably withdrawn from the insert with the form
board, but should the ?ller member happen to
stick and the nails 16 be pulled therefrom, said
?ller member may be readily removed by a sep
arate operation,
The devices illustrated may be modified in
many respects within the spirit and scope of the
invention as de?ned in the appended claims.
The invention, therefore, is not limited to the
speci?c constructions and arrangements shown
in the accompanying drawing.
