U T H U N P on m w R W FIG.2
United States Part 3,202,393 FGRE I HOLDING BRACKET Chester W. Pettit, Box 64, Greenford, Ohio Filed Aug. 30, 1952, Ser. No. 229,477 3 Claims. (1. 249-2) This invention relates to a form holding bracket and more particulmly to a bracket employed in connection with holding forms in which concrete is being poured.
The principal object of the invention is the provision of a form holding bracket for use in bridge deck constructions wherein a curb is formed adjacent a drainage channel in the edge of the roadway of the bridge deck.
A further object of the invention is the provision of a form holding bracket which may be quickly and easily secured to a structural member of a bridge deck and which in turn may be used to position a form in desirably spaced relation to said form so as to facilitate pouring of concrete thereagainst.
A still further object of the invention is the provision of a form holding bracket which is so devised as to become an integral part of a bridge deck construction including a U-shaped drainage channel and wherein said form holding bracket forms a reinforcing member with a concrete curb :and/ or sidewalk formed thereabout.
A still further object of the invention is the provision of a form holding bracket which is relatively inexpensive to manufacture, simple to use and which is therefore expendable and which operates to save a great deal of time in positioning forms for holding concrete in connection with a bridge deck structure.
The form holding bracket disclosed herein comprises an improvement in the means and methods heretofore employed in forming concrete curbs or roadways along the sides of bridges and particularly those wherein a metal channel is used as a drainage member at the end of the actual roadway. In general bridge construction practice, the roadway for motor vehicles and the like is formed with a depressed U-shaped metal channel along its longitudinal edges and which channel is apertured at intervals and connected to suitable drain pipes. Such channels provide the beginning of a curb or guard or sometimes a sidewalk construction integral with the bridge deck and it is therefore necessary that concrete fiorms be positioned adjacent said drainage channels and extends thereabove the desired height of the curb, guard or sidewalk so as to form means with the channel against which the concrete may be poured and thereby formed in a desirable substantially vertical edge section with a horizontal top portion forming the curb top, guard or sidewalk as the case may be. Heret'ofore, the forms used for this purpose have been individually custom made on the job and sometimes positioned within the drainage channel or otherwise insecurely held so that a great deal of time, effort and labor were was-ted in the arrangement of the forms which were necessary to hold the concrete being poured.
The present invention comprises an expendable form holding bracket, several of which are simply tack welded to the back of the drainage channel and which brackets extend upwardly therefrom at an angle relative thereto and each is provided with drilled and tapped openings so that bolts may be positioned therein to extend outwardly therefrom and which bolts may be positioned through holes in wooden or metal form members which are thereby temporarily secured thereto while the concrete is being poured. At such time as the concrete sets, the bolts are removed by unscrewing the same and the holes which remain are filled with cement. The fiorm holding brackets remain in the poured concrete as reinforcing members where they serve advantageously for this particular purpose as well as in their intial function of holding the forms in position.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being the intention to cover all changes and modifications of :the example or" the invention herein chosen for purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention.
The invention is illustrated in the accompanying drawlng, vh'erein:
FIGURE 1 is a perspective view of the form holding bracket.
FIGURE 2 is a cross sectional elevation through a por tion of a bridge deck incorporating the form holding bracket and illustrating a concrete form secured thereto and concrete poured thereagainst.
By referring to the drawings and FIGURE 1 in particular, it will be seen that the form holding bracket comprises an elongated longitudinally arcuate metal body member or support bar All which in its typical size and configuration would be approximately 8" long with a majority of that length formed at an angle relative to an end section 13 which is approximately 1 /2" in length or more, and to which end section a weld block 1d is integrally secured. As illustrated in FIGURE 1 of the drawings, the elongated body member 1i? is'shown provided with a pair of longitudinally spaced threaded apertures 11 and 12 and the end section 13 which is relatively shorter than the elongated body member ill and formed at an angle thereto is generally indicated by the numeral 13 and carries as an integral part the weld block 14. In a typical application, the elongated metal member 16 would be approximately thick and 1% wide and the angular positioning of the elongated portion of the body member id relative to the end section 13 would position the upper end of the elongated body member it? approximately 2" to one side of a vertical center line extending through the lower end section 3 to which the weld block 14 is attached. It will be understood that the dimensions given here are for illustrative purposes only and represent a preferred form of the invention and that the dimensions may obviously vary depending upon the particular application and location of the bridge deck structure and the curb, guard or sidewalk in which the device is used.
By referring now to FIGURE 2 of the drawings, it will be seen that a bridge deck construction having a metal deck member 15 may be seen which is apertured as at 16 to permit the vertical positioning of a drain pipe 17 therethrough. The upper end of the drain pipe 17 communicates with the lowermost part of a cross-sectionally U- shaped metal drainage channel 18. One of the arms of the U-shaped channel 18 is relatively higher than the other and therefore extends above the roadway surface which is formed of concrete 19 as known in the art and which is indicated by S. It will be observed that the outer one side of the U-shaped drainage channel 1% acts as a form member against which the concrete roadway may be poured and that this same concrete extends beneath the drainage channel iii in a typical bridge deck construction and against the other outer side of the drainage channel 13 where a curb, guard or sidewalk is usuall 1 positioned. In the disclosure as seen in FIGURE 2, the curb, guard or sidewalk is shown as formed of concrete with an outermost metal member 20 defining its outermost edge and with a center portion thereof broken away. The weld block i l of the form holding bracket is shown tack welded to the outside of the longer arm of the U-shaped drainage channel 18 at a point adjacent the uppermost edge thereof so that the elongated angnlarly disposed elongated body member lid of the form holding bracket is oliset the present invention is used.
" inwardly of the curb, guard or sidewalk to be formed relative to the upper edge of the drainage channel18.
Bolts 21 and '22 are engaged in threaded apertures 11 integral heads 26 and 27 formed thereon so that after the concrete 19 has been poured between the form 25 and the member20 heretofore referred to, the bolts 21 and 22 may be rotated by engaging the heads 26 and 27 thereof with appropriate wrenches and thereby removing them for their engagement in the form holding bracket 10 which operation will permit the removal of the form 25.
It will be understood that a plurality of the form holding brackets are used in spaced relation to one another along the longitudinal edge of the drainage channel 18, each being welded thereto as above described and each provided with. the threaded apertures lland 12 and arranged to hold an appropriate concrete form'such'as the form hereinabove referred to. When the bolts 21 and 22 have been removed together with the form 25, the openings remaining are patched with cement, and it will thus be obvious to those skilled in the art that the form holding brackets remain in the'concrete as reinforcing members thus serving the dual purpose of first holding the forms which shape the concrete when it is poured and secondly reinforcing the concrete when it has set.
It will be understood that the example illustrated in FIGURE 2 is of a preferred embodiment of the invention and that in some roadway constructions metal decks or roadways are used rather than concrete as shown herein but that in'practically all such constructions where the U-shapeddrainage channels are incorporated, the curbs, guards or sidewalks are poured adjacent'thereto and in such constructions the form holding bracket comprising It will thus be seen that a plurality of the devices are used in each bridge deck construction wherein concrete curbs, guards or sidewalks are installed at the edges of the roadway and that by the simple and economical exaaoaae 4 r 1 having an offset lower end portion secured to one side of one side wall of said U-shaped drainage channel, said concrete form being in contact with the other side of said side wall, spaced threaded apertures in the upper portion of said elongated metal supporting bar and fas teners positioned in said apertures and extending through and engaging, said concrete form, saidupper portion of said supporting bar being in spaced parallel relation to' said concrete form.
2. The combination set forth in claim 1 and wherein said side wall of said U-shaped drainage channel to which said elongated metal supporting bar is attached extends above the other side wall thereof.
3. An expendable form supporting bracket and reinforcing member for use'in a bridge deck'construction incorporating a tU-shaped metal drainage channel and wherein a concrete member is formed adjacent said U-shaped channel and comprising an elongated metal body member having two angularly related substantially planar'portions, one portion of which isshorter than the other, a rectangular weldblock smaller in size than said shorteriportion and having spaced surfaces one of which is welded to one surface of said shorter portion with the bottom edges of 'said'weld block and said'shorter portion lying on the same plane and forming means for spacing said elongated metal body member relative to said U-shaped metal drainage channel when said weld pendable 'nature of the devices they facilitate the rapid installation and removal of the concrete forms thereby saving considerable labor and cost and at the same time remaining in the concrete as suitable reinforcing members therefor, and having thus described my invention, what I claim is: a 4
1. The combination of a bridge deck construction-incorporating'a U-shaped drainage channel having spaced side walls and means for supporting a concrete form above one side of said U-shaped drainage channel, said means comprising an elongated metal supporting bar block is welded thereto, bolts engaged in threaded apertures in the longer portion of'said elongated metal body member and adapted to extend through-and engage forms a 'for containing concrete to be poured'thereagainst.
