'7 Claims. (Cl. 72-—115)
This invention relates to building construction
members and composite stud and key members
associated therewith.
This invention is a division of my application
5 Serial No. 698,433, ?led Nov. 17, 1933, for Secur»
ing members for self supporting structural build
ing units, Patent No. 2,017,441 of October 15,
1935, which patent is a continuation in part of
my prior Patent No. 1,965,601 of July 10, 1934,
10. ?led June 4, 1929, which patent is in its turn a
division of my Patent No. 1,877,898 of September
20, 1932, ?led July 27, 1928.
The speci?c details of my improvements hav»
ing been set forth in the application. above re
ferred to, they will be presented here solely for
the purpose of establishing the cooperative rela»
tionship between the several features, in order
to more clearly illustrate the patentable novelty
of the several parts in their speci?c structures
20 and in their combinations as previously set forth.
The examples shown are given merely by way
of example, for since the underlying principles
may be incorporated in their speci?c structures,
it is not intended to limit the constructions to
the forms shown, except as such limitations are
clearly imposed by the appended claims.

Referring more particularly to the drawings,
45 the improvements of the present invention in
clude novel keying and batten strip» or ?ller and
stud members, designated generally by the nu
meral i0, associated with bulbous post and key
members, designated generally by the numeral 29,
to form composite studding and supporting struc—
tural joints for buildings. The members 29, are
preferably provided with means adapted to re~
ceive and secure Spaced panels 3t, 32 of grid
members 36, all as will be described more in detail
The structural member In, and as shown in the
drawings, will now be described. This member,
which is adapted to serve as a composite struc~
tural keying ?ller and batten member, comprises
continuous parallel wall sections H and I2 spaced
from inner wall sections l3, Id. The inner wall
sections are joined by a transverse web member
£5 with which is associated parallel spaced web
sections it separated by a gap ll. The inner
walls l3, M are severally composed of symmet~ 10
rical wall sections 13a, lSl), and Ma, lib, each
terminating in a keying and locking shouldered
?ange section designated generally by the numer
al is, and forming duplex keyways.
The arrangement of parts comprising the mem 15
bers iii is formed, by preference, from a single
sheet or strip of metal of suitable composition and
of a desired gauge or thickness, depending on the
particular structural purposes to which the mem
ber is to be put.
Considering the novel structural member 10,
in further detail, it will be appreciated that the
external wall sections H and i2, together with
the mutually inturned ?angeportions l8 serve as
tension and locking portions of the keying mem
ber when assembled for use in suitable com
posite stud or joint constructions.
The keying
or stud member IE will thus comprise two struc
tural side portions ll, l2, integrally joined by an
intermediate, transverse web member lb. The 30
spaced arrangement of the walls of the member
gives a desired resiliency and spring-gripping
action and the substantially columnar sheet
metal shape gives a maximum structural strength
with a minimum of material. To provide a plas
tic keying and bonding surface, as well as to
decrease the over-all weight of the member with
out decreasing the structural strength thereoi
the panels H and i2 may be provided with
punched-out or cut-out portions or sections 40
designated generally by the numeral l9. Metal
lath strips or like plastic-receiving surfaces may
be associated with the faces. A cut-out 19 may
also be formed in the transverse web section l5
oi the member, as well as in the panel or side 45
portion thereof.
The novel stud or stanchion members 20
adapted to cooperate with the duplex keyways of
the keying members 10, will now be described.
These members comprise a head 2! with lateral
bulbs or beads 22 adapted to ?t in and mate with
the inner sides of the locking ?anges 58 of the
key member Ill. These post sections are further
provided with parallel web portions 22a ter~
minating in flared-out or shouldered portions 23.
The sections 2|, 22, and 23 form a bulbous key
adapted to be received in and held by the key
way-forming portions l5, l6, and [8 of the mem
ber l0. Parallel terminal ?anges 24 may be
formed as continuations of the sections 23, and
generally at right angles thereto, as shown more
particularly in Figs. 3 and 5. Panel members 3|,
32, may be applied on the exterior of the flanges
24 and secured thereon by any suitable means,
10 such as welding or brazing or by mechanical
means, including rivets, bolts and nuts, all as in
dicated generally at 25. Where the panel mem
bers 3| , 32 are to be crimped in place or held,
the sections 26 may be continued to form an
15 S-shaped member 26 having an outer flange sec
tion 2'1 forming a channel adapted to receive
the ends of the panel members and secure the
same mechanically as by crimping or by welding
or brazing, or other mechanical means, all as
20 generally indicated by the numeral 28. With this
construction it will be seen that the key, stud,
stanchion or post members 23 may be suitably
conformed at their terminal ends to receive any
desired panelling in any manner desired.
The resulting completed grid members 31] will
comprise end keying post and spacing sections 20
and associated panellings 3|, 32, secured to and
spaced apart by the post members. The panel“
securing means may vary according to the designs
The head portions 2| of these end post
sections may be apertured as indicated at its.
These apertures may generally conform to the
similar apertures in members I0 and thus pro
vide a through~and~through connection between
35 the interiors of the grids 30. Where structural
cementitious materials are incorporated in the
members 30 for heavy structural purposes the
cementitious plastics may flow in and through the
interior of the key members I0 into the interior
40 of the grids 30. While the panel members 3i, 32
have been shown and generally designated as
being made of reinforced and supported foram
inous structural sheet material such as rigid,
expanded metal lath, it is to be understood that
45 other structural panellings may be made use of
in the constructions here shown.
30 shown.
The novel self-supporting structural building
wall units and intermediate combination locking
and batten strip members may be apertured, as
50 noted above, to receive and bond cementitious
structural plastics and ?nishes. In addition these
panel members and panel sections of the interme
diate keying members may be formed of continu
ous surfacings of any suitable material and pre
55 formed so as to permit the erection of walls and
buildings without requiring the addition of struc
tural cementitious materials. For various design
features and the like the novel keying and joint
construction of the present invention permits a
wide variety of design features to be incorporated
in the constructions. Where desired, the panel
members 3!, 32, may be so secured to the flange
sections 24 as to come flush with the surfaces
ll, l2 of the keying stud member. The joints
between the surfaces ll, I2 and abutted panel
surfaces 3|, 32, may be made as tight as possible
to give a so-called “hair-line” joint eifect. The
crimping sections 26 will ordinarily be used with
panellings 3|, 32, under conditions where it is
desired to provide an over-lay of cementitious
plastic material. The panel surfaces H, I 2 of
the members It! may be suitably ornamented to
give any desired surface ?nish.
The post sections 26 of the composite stud
75 and joint construction may be made of fairly
heavy gauge metal to provide inherent structural
rigidity and strength which is enhanced by the
con?guration of the sheet metal members. Any
lateral weaving of the wall assembly is prevented
by the con?guration of the stud post and keying
members, and the gauge of sheet metal used for
the keying member may be varied according to
the particular joint to be set up. Thus, in non
load-bearing joints the sheet metal out of which
member ID is formed may be a relatively light 10
gauge having sui?cient inherent strength to per
mit the panel sections I I, I2 and associated look
ing ?anges Hi to serve as tension members in a
joint construction in which the tension is to be
applied in the direc ion of the plane of the sur
faces of members H and i2. The members l6
are not primarily intended to be utilized under
conditions wherein a transverse pull on web mem
ber or section I5 is to be effected.
Referring now to Fig. 6 a side wall of inter
secting wall keying member 4E3 is shown. This is
also preferably a formed sheet metal member of
appreciable length and having a head or rail sec
tion Iii adapted to be'received into auxiliary key
ing sections 42 of self-supporting grid structures 25
shown and disclosed in my prior Patent 1,968,045
of July 81, 1934, for Building construction. The
members 49 are provided further with opposed
parallel sections 42, each terminating in ?anged
feet 43, and the latter in turn, including mutually 30
inturned sections 44, de?ning an aperture or gap
45 therebetween. In such construction the head
or rail section 4| may ?t in an auxiliary keyway
section 42 and the foot section 33 adapted to fit
in and mate with a keying section 46 formed in a 35
structural unit and more particularly shown in
my application Serial No. 698,433, ?led November
17, 1933, for Securing members for self-support
ing structural building units. These structural
members thus permit the assembly and erection 4.0
of ?ying walls or angularly disposed partition
walls, Where desired, and with a minimum of
materials and structural costs.
The several keys and associated keyways,
whether formed integrally with the grids as ends 45
thereof, or whether formed separately in any de
sired con?guration and later secured to the side
panels in any of the ways described above, form
composite structural members adapted to serve as
studs, stanchions, column members and beam 50
The section or thickness of the metal
entering into these constructions may be varied,
as desired, according to the loads to be imposed
on the members and whether they are to serve
as vertical supporting members or as beam or floor
Referring now to Fig. 7, there is shown a con
struction more particularly described in my Pat
ent 1,968,045 of July 31, 1934, for Building con
struction, in which the grids are keyed together
by the different types of keys, as indicated. Cer
tain of the grids are shown ?lled for insulating
purposes, and the like, with insulating material
such as mineral wool, glass wool, slag wool,
ground cork, asbestos, magnesia, gypsum base
materials, sawdust or other solid or pulverulent
insulating materials, designated generally by the
numeral ll‘l. These materials may be formed
into units or blocks adapted to completely ?ll
the interior grid spaces, or the materials may be
used in bulk form ?lling the grids wholly or in
part, as may be desired, or they may be made
into slabs, blankets or sheets designated, gen
erally by the numeral I I6, adapted to ?t into the
sides of the grids, and of such a length as to be
keyed between the said sides of the adjacent key
way. While mineral insulations have been de
scribed, it will, of course, be understood that any
suitable vegetable insulant materials, such as
sugar cane refuse, corn-stalk refuse, or other
such materials may be made use of, these ma~
terials being known in commerce as bagasse,
celotex and insulite.
The above construction prevents the transfer
10 of heat, makes the walls sound-proof, eliminates
the passage of moisture from the exterior of the
house to the interior, permits the use of metal
and concrete plastics in the Tropics, and makes
a vermin-proof house. By providing suitable
apertures in the web sections of the keyways or
keys, the cross-sectional mass of the metal in
the web is reduced to a minimum without reduc
ing its structural strength.
This reduction in
mass of the web metal imposes a distinct resist
ance to the travel or transfer of heat through
the mass of the web as such heat transfer is
essentially a function of the amount of metal
available as a heat-conducting path. Such a
feature increases the insulating effect between
the panels of the several grid members. The
usual service pipe and connections ill‘! may be
disposed inside of the grids.
It will now be appreciated that there has been
provided improved key members for self-sup
porting structural building members, which key
members are characterized by a variety of forms
and high structural efficiency when combined
with abutted stanchion or stud members or beam
members to form composite structural members
ill) which may be readily inserted in‘ place to lock
abutted building units in place and to form with
the said units, permanent structural members
having the maximum of crushing and bending
strength yet being characterized by a minimum
40 of weight and a desirably high resistance to the
passage or transfer of heat therethrough.
While certain novel features of the invention
have been shown and described and are pointed
out in the annexed claims, it will be understood
that various omissions, substitutions and changes
in the forms and details of the device illustrated
and in its operation may be made by those skilled
