ATTORNEY Patented Aug. 9, 1938 ' 2,126,511 UNITED STATES PATENT QFMQE 2,126,511 DIAGONAL BRACHNG FOR METALLIC STRUCTURES ' Edward L. Soulé, Oakland, Calif.V Application April 18, 1936, Serial No. 75,130 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. In the drawings, Fig. 1 is an elevation of a portion of a two story metallic wall frame illustrating diagonal brace members secured thereto in accordance with my invention; l Fig. 2 is a similar View illustrating the man ner in which the invention may be adapted to the bending of brace members to avoid window openings and the like; el Í) Fig. 10 is an enlarged section of means em ployed for connecting the lower ends of the di agonal braces with the foundation of the wall Fig. 3 is a, similar view of a one-story frame, illustrating a further use of the securing mem bers in connection with the placing of braces to avoid a window-opening; Fig. 4 is an -enlarged detailed sectional view if» of one of the securing members illustrated in Fig. 1; Fig. 5 is a similar View of another of the se curing members illustrated in Fig. 1; ' 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 2 2,126,511 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: 1.
