6 Claims. (Cl. 18S-_34)
This invention relates to improvements in di
agonal bracing for metallic structures, and per
tains particularly to means for connecting di
agonally placed brace members with vertical and
structure.
horizontal members of a structural metal as
(Il
sembly.
In structural metal buildings horizontal wall
loads such as are set up by wind and seismic
forces are counteracted by diagonal members
connecting the walls at various points with their
foundations so that these loads will be directly
transmitted to the foundations.
It is the object of the present invention to
provide a simple andimproved form of connec
tion for the ends of such diagonal braces with
the metal framework of the walls and with the
foundation and to provide means for this pur
pose that will effect a proper transmission be
tween the connected elements of the forces en
countered and to provide means that are simple
in construction and readily adapted to the vari
ous conditions that may be met in ordinary con
struction.
One form of my invention is exempliñed in the
accompanying drawings, wherein its application
under various conditions is illustrated. Detailed
reference to the drawings is made in the follow
ing specification, wherein further of the objects
and advantages of the invention are made ap
parent.

'
Fig. 6 is a similar View of a combination of the
I?) securing members as illustrated in Fig. 2;
Fig. 7 is an enlarged perspective view of the
securing member illustrated in Fig. 5;
Figs. 8 and 9 are enlarged sectional views of
the application of the securing member as il
55 lustrated in Fig. 3; and
’
Figs. l, 2 and 3 of the drawings illustrate
structural metal walls supported on concrete
foundations ill. A sill II rests upon the founda
tion and vertically extending parallel studs I2
are supported on the sill and are joined at their
upper ends by a plate I3.
In Figs. 1 and 2 a two story wall is illustrated
and a horizontal ledge i4, which may be in the
form of an angular member welded to the edges
of the vertical studs, deiines the dividing line
between stories and lends rigidity to the studs.
The sills, studs and plates are all of structural
metal. The studs I2 are of I-shaped cross sec
tion and their web portions are, as illustrated
in Fig. 7, perforated to decrease their weight
without materially reducing their strength to 9
oppose normal structural forces. All metal parts
of the wall are secured together at their points
of contact with each other by suitable means
such, for example, as welding.
v
Diagonal brace members, shown at I5 and I6 25
in Fig. 1, are passed through the perforations
in the webs of the studs and connected at their
ends with the studs and in some cases with the
foundation to resist lateral forces such, for eX 30
ample, as may be set up by wind and earthquake.
It is to the means for connecting such braces
with the vertical and horizontal wall members
that the present invention is particularly di
rected.
In Fig. l the upper ends of the braces I5 are 'I'
connected with the I-beam studs through the
medium of connecting members I'I. In Fig. 4
such a member il’ is shown as comprising a semi
cylindrical shell welded, as`at E8, along its up
40
per edge and IQ along its lower edge to the web
of the I-beam and perforated at 2B to receive
the end of a brace I5, which is threaded to re
ceive a nut 2l. The perforation 2@ in the shell
ll may be formed at any required point to per 45
mit the brace I5 to be disposed at any suitable
angle, and it is preferred that the perforation
be placed at such a, point that the center of the
brace I5 will lie along a radius of the semi
cylindrical shell Il', thereby forming a seat
against which the nut 2| may be drawn which is
tangent to the outer surface of the shell. When
the elements have been placed in the position
illustrated in Fig. 4, the nut is tightened to place
the proper tension on the brace I5.
This samev 55

arrangement of the elements may be used at the
lower ends of the rods, if it is desired, to pro
vide for taking up on the rods from both ends.
The lower ends of the brace rods I5 in Fig. l
and the upper ends of the rods I6 are connected
with the studs in the manner illustrated in Figs.
5 and 7, wherein the shell I'I is shown as per
forated at two points :for the reception of both
the brace rod I5 and the brace rod I6. Fig. 7
also illustrates the manner in which the semi
cylindrical shell Il spans the perforation in the
web of the I-beam and as a solid fitting against
the imperforate edges of the web.
Means for connecting the lower brace rods I6
with the foundation are illustrated at 22 inv Fig.
1 and are also illustrated in Fig. l0. Anchor
bolts 23 are let into the concrete foundation and
extend upwardly through perforations in the sill
II and have their upper ends bent to an‘angle
parallel to the angle at which the brace I6 is to
be disposed. The brace rod I6 may be connected
with the upper end of the anchor bolt in any
desired manner, a splice weld, such as illustrated
in Fig. 10, being suitable for this purpose.
Fig. 2 illustrates the use of the semi-cylindrical
shell I ‘I for the purpose of bending the brace rods
to avoid Window or door openings formed in the
wall at 25. In this ñgure and in Fig. 8 a semi
cylindrical shell is illustrated as welded to the
web of one of the studs and a brace rod 26 passes
over the shell and the shell serves as a bearing
over which it is bent and to which it may be
welded for additional rigidity. As illustrated in
Figs. 3 and 9, brace rods 21 may be bent over the
upper corners of a window opening in the same
manner as they are bent in Figs. 2 and 8.
In the lower portion of Fig. 2 the upper ends
of brace rods 3U and the lower ends of the brace
rods 26 are shown as terminating at substantially
the same point adjacent the corner of a window
opening and in this construction, which is best
illustrated in Fig. 6, it is possible to apply ten
sion to both of the brace rods which terminate in
this position.
The semi-cylindrical shell
Il
lwelded to one side of the stud receives the rod 26
in the usual manner and a second shell I'Ia, which
is a quarter cylinder, is positioned at the junction
of the vertical stud and the horizontal window
header 3 I.
50 The connecting member described above is in
expensive in construction and is adapted to the
forming of connections between the brace rods
and the vertical studs at any desired angle, and
the manner in which it is secured across the perfo
rated webs of the I-beam makes insertion and
adjustment of the brace rods very simple, and
also insures that the diagonal stresses are prop
erly taken up by these members in conjunction
with the horizontal members and foundation,
thus releasing the vertically extending members
from any horizontal loads or stresses.
While I have illustrated the preferred form
of my invention and described the same only in
connection with a few of the uses to which it may
_ be adapted, it should be understood that the in
vention is not limited by the foregoing disclo
sure and that it may be modified within the scope
of the appended claims.
Having thus described my invention, what I
claim and desire to secure by Letters Patent is:
