Application November 15, 1945, Serial No. 628,683
This invention relates to braces r stays designed primarily for use in building, and particularly in the construction of concrete structures wherein it is necessary to set up heavy columns in forming the framework around which the concrete is poured.
An important object of the invention is to provide a device of this character which may be adjusted while in its supporting position, whereby the column may be readily and accurately adjusted to its proper position for accomplishing its purpose.
Another object of the invention is to provide a brace embodying a horse which may be moved in conjunction with the brace proper, when it is necessary to support tie rods or the like adjacent to the columns.
With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawing:
Figure 1 is a perspective view of a device constructed in accordance with the invention.
Figure 2 is a view illustrating the threaded adjusting means for adjusting the brace rods of the device.
Figure 3 is a sectional view through the support to which the brace rods are pivotally connected.
Figure 4 is a fragmental perspective view illustrating the manner of securing form boards to a supporting column.
Referring to the drawing in detail, the device comprises a plate 5 having a pair of upstanding ears 6 between which the threaded section I of the brace rod 8 is pivotally mounted, the threaded section I being of a length to extend an appreciable distance into the hollow brace rod section 9, so that the brace rod 8 may be lengthened or shortened to meet various requirements of use.
As clearly shown by Figure 2 of the drawing, an annular flange I0 is formed at the lower end of the hollow section 9, which flange provides a shoulder over which the annular flange l l of the collar l2 rests, the collar i2 being secured to the adjusting hand wheel I3 which moves over the threaded section 7 of the brace rod 8. At the upper end of the hollow section 9 is a hook l4 adapted to hook into the eye-bolt l5 that is positioned in an opening of the column supported by the device, the column in the present showing being indicated by the reference character It.
The plate 5 is formed with openings through which the spikes H are driven, whereby the plate may be held against movement with respect to the surface on which the device is positioned.
The plate 5 is also formed with upstanding ears l8 between which the threaded section iii of the lower brace rod is pivotally mounted,the threaded section i9 being constructed to telescope Within the hollow section 26, there being provided a hand wheel 2|, swiveled on one end of the hollow section 20 to move the hollow section over the threaded section of the lower brace. A hook 22 is formed on the outer end of the hollow section 29 and is also designed to hook into the eye-bolt 23 that is secured in one of the openings of the column it.
Used in conjunction with the brace rods is a horse 24 which is used in adjustably supporting reinforcing rods or tie rods which may be used in the building construction. As shown the horse it is provided with elongated openings 25 formed in the legs 28 thereof, the elongated openings 25 accommodating the supporting rod 27, the ends of the supporting rod extending through the openings where they are threaded and provided with nuts 28, whereby the supporting rod may be secured in various positions of vertical adjustment.
Supporting hooks 2e are adjustably supported on the upper bar of the horse, each supporting hook comprising a yoke 36 adapted to fit over the cross-bar or" the horse, the rods 35 of the hooks passing through openings formed in the ends of the yokes (it, there being provided hand wheels 32 on the threaded upper ends of the rods for adjusting the rods vertically. The reference character 33 indicates hooks that are formed on the lower ends of the rods or hooks iii, the hooks providin supports to fit around the supporting rod 2? for holding the rod firmly against movement under the weight of the structure supported. These supporting hooks 29 afford means whereby the hooks may be adjusted vertically after they have been positioned and are supporting the weight of the reinforcing rods 34 which form a part of the structure being erected, and around which the concrete is poured.
The upward movement of the rods 3:3 is limited by cross rods 35 which are positioned in openings of the columns l6, and against which the rods 34 are drawn by the supporting hooks 29. Due to this construction, it will be seen that after the device has been set up to support a column or reinforcing rods, a final adjustment may be made to accurately position the columns or rods.
As shown by Figure 4, the device may be used in supportin form boards indicated by the reference character 36, when erecting concrete structures wherein the concrete is poured or tamped. With applicants device heavy columns and forms may be temporarily braced and held in the proper upright positions :during :t-he positioning and curing of the concrete or plastic material in the construction of a building, after which the device is removed with the removal of the columns and forms.
What is claimed is:
1. A concrete reinforcing rod support for concrete structures, comprising a horse having legs, a horizontal rod connecting the legs of the horse, adjustable hooks depending from the horse in which the rod is supported, said rod providin a support for reinforcing rods of the concrete structure being formed, the reinforcing rods extending at right angles with respect to'the horizontal rod, a column "having spaced openings disposed adjacent to the horse, a cross rod fitted 'in'an opening of the column, said cross rod extending beyond 5 ing rods of concrete structure, during the pouring and curing of the concrete structure, comprising a horse having legs formed with vertically .disposed elongated openings, a horizontal supporting rod connecting the legs, the ends of said rod being extended through the elongated openings, nuts on the ends of the rods securing the rods in positions of adjustment in said openings, vertically adjustable depending hooksxmounted on the horse, hooking around the supportingzrodgsaid supporting rod providing a support for horizontal rein- :forcing rods forming a part of the concrete structure being formed, a column disposed between the reinforcing rods holding the reinforcing rods spaced apart, and a cross rod on the column engaging said reinforcing rods and securing the rein-forcing rods against vertical movement.
