As shown particularly in FIG. 3, the top flange 12 and bottom flange 14 of the C-beam 10 are provided with stiffening lips 26 (FIGS. 1-3). Retaining means 27 (FIG. 3), such as a retaining lip 28 or the like, on the saddle flange 24 engages the stiffening lip 26 on the bottom flange 14 to retain the bottom flange 14 of the C-beam 10 in intimate contact with the saddle flange 24. I
A vertical support member 30 (FIGS. 1-3) suitably a hollow pipe or the like, depends from welds 31 (FIG. 2) to the saddle flange 24 downwardly toward a foundation 32 (FIG. 2) and is provided with a free end 34 (FIGS. 1-3). Elevating means 36 (FIGS. 1-3) are mounted on the foundation 32 and are engageable with the free end 34 of the vertical support member 30 to reciprocate the saddle 20 and the C-beam 10 with respect to the foundation 32.
Elevating Means 36 As shown in FIGS. l-3, the elevating means 36 has a threaded rod 38 upstanding from an anchor plate 40 (FIGS. 1,2) on the foundation 32 projecting into the hollow vertical support member 30. The means utilized to elevate the vertical support member 30, may for example, be a threaded nut 42 (FIGS. l-3) or the like, rotatable on the threads of the threaded rod 38 and engageable on its upper surface with the free end 34 of the vertical support member 30 to cause the reciprocating movement of the saddle 20 and the C- beam 10 with respect to the foundation 32.
V-Shaped Support Member 44 A V-shaped support member 44 (FIGS. 1-3) is provided having a first support leg 46 (FIGS; 1,2) and a second support leg 48 (FIGS. l-3), both legs 46,48 terminating in a vee 50 (FIGS. l-3). The vee S is affixed to the vertical support member 30 adjacent its free end 34 as by encircling welds 5 2 (FIGS. 1,2) or the like. For the purpose of obtaining maximum projected bearing area, A FIG. 2, along the saddle flange 24 for the bottom flange 14 of the C-beam 10, the first support leg 46 and the second support leg 48 are connected at first connections 54 (FIGS. 1,2) (suitably welds or the like) to the saddle web 22 adjacent the top of such saddle web 22. In addition, in order to minimize torsion in the C-beam 10, the first support leg 46 and the second support leg 48 pass approximately through, as shown in FIG. 3, the shear center C, of the C-beam 10.
In order to strengthen the beam web 16 against collapse of such beam web 16 under a lateral load on the C-beam, the first support leg 46 and the second support leg 48 project beyond the top of the saddle web 22 and are connected at second connections 56, FIGS. l-3, (suitably clamps or the like) about the upper ends of the first support leg 46 and second support leg 48 which clamps 56 are secured to the beam web 16 by fasteners 60 (FIGS. 1,2) or welds (not shown), or the like.
It will be noted from a consideration of FIGS. 1-3 that the maximum projected bearing area A (FIG. 2) along the saddle flange 24 for the bottom flange 14 of the C-beam by utilizing the angle B (FIG. 2) is about 30. The angle 0 which the first support leg 46 and the second support leg 48 makes with the horizontal (FIG. 2), is such that 0, (FIG. 2), the angle of inclination for the first support leg 46 is equal to the angle of inclination 0, (FIG. 2) which the second support leg 48 makes with the horizontal. In addition, the length L; (FIG. 2) of the first support leg 46 is equal to the length L (FIG. 2) of the second support leg 48. The distance A, (FIG. 2) from the center-line of the vertical support member 30 to the first connection 54 of the first support leg 46 with the top of the saddle web 22 is substantially equal, as shown in FIG. 2, to the distance A, (FIG. 2) from the centerline of the vertical support member 30 to the first connection 54 between the second support let 48 and the top of the saddle web 22.
It will be understood by those skilled in the art that the angles of inclination 0, and 0 are critical in the range such that the cotangent of either 0, and 0, lies in the range of about 1.0 to about L4.
In order to provide positioning of the support assembly 18 in three planes, the anchor plate 40 ispro vided as shown in FIG. 1 with longitudinal slots 62 and such anchor plate 40 is secured to the foundation 32 as by anchor bolts 64 (FIG. 2) or the like.
In order to prevent separation of the beam web 16 from the saddle web 22, fastening means such as screws, bolts, welds, or the like 66 (FIGS. 1,2) extend through or connect the saddle web 22 to the beam web ALTERNATIVE EMBODIMENTS It will be understood by those skilled in the art that alternatively as shown in FIG. 4, the C-beam 10" does not have a stiffening lip 26 on the bottom flange 14. The retaining means 27 may comprise alternatively either a fastener 68a extending through the retaining lip or saddle lip 284 of the saddle 20 or alternately, a fastener 68b extending through both the saddle flange 24 and the bottom flange 14.

In FIG. 13, the vertical support plate 30 divides the C-beam 10 into two unequal spans, namely span B, being greater than span B In this case, the length of the first support leg 46 (L is greater than the length L of the second support leg 48". Further, the angle of inclination of the second support leg 48 is greater than the angle of inclination 0 of the first support leg 26". In addition, the horizontal distance A, is greater than the horizontal distance A FIG. 13 shows the ends of the C-beam resting on foundation walls 116.
In FIG. 14, the vee 50 on V-shaped support member 44 is eliminated and the ends of the first support leg 46 and the second support leg 48 are secured, as by welds 118 or the like, to the vertical support member 30. In this case, the length L, of the first support leg 46 is greater than the length L, of the second support leg 48". The height H, from the weld 118 to the first connection 54 between the first support leg 46 and the saddle web 22 is greater than the height H, from the weld 118 to the first connection 54 between the second support leg 48 and the saddle web 22.
