2 Claims.
This invention relates to improvements in the
method of construction of hollow concrete walls,
?oors and roofs, andmore particularly to the
arrangement and utilization of my improved con
' stru’ction units ‘.or elements which are readily
' transported to a‘particular building job, and with
'- which any desired building or' construction may be
~ easily and ef?ciently built.
‘An object of the invention is to provide a plu
10‘ rality of my improved inserts or forms made from
- sheet metal‘ which cooperate with sheets of metal
vlath or expanded metal which are spot welded
‘thereto, and when properly positioned on a build
ing jobfwill be ?lled with concrete and with suit
,15, able‘reinforcing rods or strips, to form the studs
or joists, after ‘which as many layers of plaster‘
and concrete may be applied to the inner and
‘ outer sheets of metal lath which are spaced apart
the distance of said inserts, thereby forming the
“201 inner and outer walls of the building, respectively.
- Aiurtherobject of the invention is to provide
(CI. 72-48)
a wall showing a nailing insert incorporated in a
stud;

In ‘carrying out my invention, I provide a plu
rality of sheet metal inserts or forms I which are
formed at their opposite ‘ends with laterally ex
tending ?anges 2, which in turn, have their outer
or free extremities bent or angled inwardly as'C
at 3, and may be referred to as locking ?anges.
The inserts I cooperate with sheets of metal
lath or expanded metal 4, said lath lying in con
tact with the ?anges 2, and being spot welded at
intervals to said ?anges, as indicated at _5. The 20
ends of the lath '4 are bent inwardly over the
improved sheet metal inserts or forms having
locking ?anges 3,‘ and extend-a short distance
sheets of metal ‘lath or expanded metal spot
welded thereto, which cooperate with suitable fas
25 tening means to support the inserts in the de
sired position and relation, whereby a double
Walled construction may be built having air spaces
there'beyo'nd, and serve to tie into the concrete
when poured into the space between adjacent in
between the walls.
'
A still further object of the invention is to pro
30 vide an improvedbuilding construction in which
my improved sheet metal inserts or forms will‘
be used in conjunction with sheets of metal lath
or expanded metal spot welded to the inserts,
whereby the walls, floors and roof of a building
35 may be constructed, all of which .are double
walled, suitably reinforced, and forming air spaces
between the walls, which are covered with plaster
or cement, as‘desired.
Other objects will appear as the description
40
proceeds.

.
As clearly illustrated ‘in Figures 1 and 3, units
will be formed including a pair of oppositely
spaced sheets of metal lath 4, with cooperating
connecting inserts l spot welded thereto adjacent
their ends or sides.
When the actual construc
tion work is being done, these units will be placed
26
30
in courses with adjacent ends of adjacent units
abutting each other and being held in place by
the locking clips or ties 6, which are slipped down
over the adjacent locking ?anges. Thus it will 35
be seen that hollow stud forms will be provided
at intervals in the wall construction, and suit
able reinforcing rods or strips of steel 1 will be
placed in these hollow forms, after which the con
crete mix will be poured therein.

In Figure 2, I have illustrated my improved ?oor
joist construction, which comprises the utilization
of inserts ll having outwardly extending ?anges
I2 at their ends, which cooperate with sheets‘ of .
metal lath or expanded metal l3.
The lath I3 is 55
2,113,875
spot welded at intervals to the ?anges l2, and is
bent inwardly to tie into the concrete form
ing the joist, when poured. A clip 6 will tie the
adjacent ends of the lath together at the lower
end of the joist form, while tie wires [4 may be
used at intervals to connect the upper or ?ared
portions of the joist form. It will be understood
the inner and outer walls of the construction, and
on the ?oors and roof thereof.
It will be found that constructions built in ac
cordance with my invention will be extremely
strong, insulated, ?reproof, moistureproof and rel
atively cheap to construct.
Many minor changes in detail of construction
that all inserts, tie wires, and clips will be per
may be resorted to without departure from the
manently left in the construction, and each will
spirit of the invention.
10 add to the strength of the construction when the
concrete mix is poured into the several forms.
In Figure ‘5 of the drawing, I have illustrated
a stud, joist or rafter construction, which is
‘
Having thus described my invention What I
claim as new and desire to secure by Letters Pat
ent of the United States is:
1. A building wall comprising spaced support
formed similarly to the other constructions shown ' ing elements each comprising two channel mem
15 in Figures 1 and 3, except that I have included .bers having reversely directed ?anges on the
a suitably formed. nailing strip or insert l5, which ?anges thereof, the channel members being held
may be either wood or metal, and of any desired ‘ in substantially abutting relationship by clips ?t
shape and form. It will be understood that ting over the inwardly directed ?anges, and wall
either the wood or metal insert 15 may be placed reinforcing members of wire mesh clamped be
in any desired position, whereby ?ooring, siding or tween the channel members at the ends thereof,
reinforced concrete‘ ?llings for the openings‘ be
roo?ng may be nailed thereto.
In Figure 3, I have shown a sectional ‘view tween the channel members and the plastic fac
ings on: the reinforcing members at the wall
through a rafter l6, which is formed approxi
mately like a stud, and as shown supports a suit
2. A building wall comprising spaced support
:25 able roof material I‘! and a plaster ceiling [8.
In Figure 4, I have illustrated how the end of - ing elements each comprising ‘two channel mem
a roo?ng rafter is supported on and tied to the bers having reversely directed ?anges on the
vside wall of ‘the building. A metal lath form I!) ?anges thereof, the channel members being held
willbe supported within the upper end of the in substantially abutting relationship by clips ?t
L30 wall 20, and will be ?lled with concrete mix and ting over the inwardly-directed ?anges,‘ Wall ‘re
faces.
‘reinforcing rods 2|, to form a substantial plate
upon which the roof proper will be seated. The
reinforcing rods ‘I inserted in the studs will ex
tend up into the rafter form, and will be bent
over, as shown. Other reinforcing rods 22 will
extend lengthwise within the rafter form, to re
inforce the same, and to tie the roof to- the side
walls of the building.
It will be understood that concrete 'mix is
poured as the building progresses, and that due
an to my improved method of construction, no delay
is required for the curing of the concrete.
Many different types of ?nishes may be used on
-
_
'
inforcing members of wiremesh clamped between
the channel members at the ends thereof, rein
forced concrete ?llings for- the openings between
.the channel members and the plastic’facings on
the reinforcing members-at‘the wall faces, a con
nection between the Wall and an angularly dis
posed partition comprising wall reinforcing mem
bers tied to the like members of the ?rst mem
tioned wall and spaced from‘each other by a sin
gle channel having reversely bent ?anges and tied 40
to the two reinforcing members of the partition.
