Claims. 1
This invention relates to new and useful improvements in brackets for supporting roadway overhang forms. I 1
Most concrete roadway or bridge spans which are reinforced or supported by steel beams have overhanging lateral margins or curb portions. Heretofore, the erection of forms for supporting these overhangs has created a considerable problem due to the necessity of maintaining a specifled grade. The forms are relatively heavy, and are usually supported by the permanent structure beams. Due to deflection of these beams during pouring of the concrete floor, it is necessary to make adjustments in the overhang forms in order to preserve the line and grade of the curb forms. Therefore, the present manner of erecting overhang forms is not only undesirable from a structural standpoint but is also expensive and time consuming.
One object of the present invention is to provide improved means for supporting a roadway overhang form which is of such construction that one of the beams of the roadway may be utilized to sustain the weight of theform as well as the load imposed thereupon.
Another object of the invention is to provide an improved supporting bracket for a roadway overhang form having connection with an adjacent roadway beam and means for rigidly supporting the form in fixed positions so as to transmit the load of said form to the beam.
A further object of the invention is to provide an improved supporting bracket, of the character described, which is supported by and adjustably connected to the outermost roadway beam and which has adjustable means for supporting a portion of the form whereby the same may be accurately positioned and maintained at the desired elevation or grade.
A construction designed to carry out the invention will be hereinafter described together with other features of the invention.
The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawing, wherein an example of the invention is'shown, and wherein:
Fig. 1 is a transverse, vertical, sectional view of the lateral overhang portion of a concrete roadway during construction thereof, showing a bracket constructed in accordance with the invention for supporting the form for said overhan Fig. 2 is a perspective view of the bracket, showing its connection and relation to the roadway beam,
Fig. 3 is an end elevation of the bracket, and
Fig. 4 is a detailed, perspective view of the lower inner portion of the bracket.
In the drawing, the numeral Ill designatesone of the outermost of a plurality of parallel, longitudinal beams (not shown) commonly used for reinforcing and supporting a roadway or bridge span which is normally in the nature of a concrete slab l I During the pouring of the slab I l a suitable form I2 is mounted between adjacent beams by transverse timbers l3 and jack members M for supporting said slab. Roadway or bridge spans of this type generally have overhanging margins or edge portions, one of which is indicated by the numeral l5, that extend laterally beyond the outermost beams Hi and may have raised or upwardly offset curbs or shoulders IS. The supporting of the forms for these lateral overhangs is the primary object of the present invention.
A plurality of supporting brackets are adapted to be suspended from the beam in spaced relation and each bracket includes an upright or vertically-disposed plate or member l8 preferably of greater width or length than height. The top edge of the plate I8 is cut oil at an angle, as shown by the numeral l9, whereby said plate is substantially triangular and its inner vertical end 20 is of greater length or height thanv its opposite or outer end 2|. A pair of alined, horizontal flanges or flat bars 22 extend longitudinally on opposite sides of the plate near the lower edge thereof from the juncture of its top edge and outer end 2! to its inner end 29. The coextensive bars 22 are welded or otherwise secured to the plate at right angles thereto and have their outer end portions reinforced by transverse, triangular gussets 23. Diagonal braces 24 reinforce the opposite end portions of the bars and preferably extend to the corner between the lower and inner ends of the plate.
A transverse, angle iron or bar 25 is welded or otherwise secured to this inner, lower corner of the plate with one flange directed upwardly in engagement with the inner end 20 of-said plate and its horizontal flange abutting the lower edge thereof. The braces 24 bear against the angle bar 25 which is centered relatively to the plate and projects equally beyond said braces (Figs. 3 and 4). In each end of the vertical flange of the angle bar, an opening 26 is formed and a nut 21 is welded or otherwise secured to said flange in overlying relation to the opening for receiving an adjusting screw or elements 28. A screwthreaded member or sleeve 29 is Welded in the inner end of the plate adjacent its upper extremity and projects longitudinally of said plate for receiving a threaded supporting element or stud bolt 30. As shown in Figs. 1 and 2, the bracket [1 is adapted to be supported by the bolt 30 and engaging within an opening 3| formed in the vertical web of the outermost beam Ill near its top flange and is held in a fixed position by a pair of suitable nuts 32 threaded upon said bolt and bearing against opposite surfaces of said web. The bracket is maintained with the lower edge of its plate and the longitudinal flat bars 22 in substantially horizontal planes by the adjusting screws 28 which bear against the lower portion of the beam web. By adjustment of the screws 28, the relation of the bracket to the beam may be varied as may be desirable or necessary. It is obvious that the opening 31 must be of a diameter greater than the diameter of the bolt 39 to permit this adjustment of the bracket.
A pair of stringers 33 and 34 are adapted to be supported by each flat bar 22 of the bracket in substantially parallel, spaced relation. Although not illustrated, a plurality of brackets are provided and the bars of each support the ends of the stringers 33 and 34. If desired, auxiliary adjusting means in the form of foot members 01' plates 35 may be carried by the flat bars 22 for supporting the stringers 34. Each foot plate 35 includes a depending stud 36 which extends through an opening in the flat bar and which is held in adjusted positions by a pair of nuts 31. An angular bracket or clip 38 may be carried by the plate I! above the foot plate for engaging the upper portion of the stringer to steady and help support the same although the foot plates are optional and have been shown only in connection with the inner stringers, it is manifest that the same may be used in connection with the outer stringers.
An overhang form 39 is mounted upon the stringers and includes the usual deck 49, box form 4|, outer side form 42 and inner side form 43 (Fig. 1) Due to the provision of the adjusting screws 28, the elevation of the overhang form 39 may be readily varied in order to maintain the desired grade. Manifestly, the coaction of the supporting bolt and adjusting screws provides a three point support for the bracket to prevent swinging or other movement of the same.
the position or elevation of the overhang form. The mounting of the bracket is so simple that the same may be readily removed upon dismantling of the overhang form. If desired, the opening 3| in the web of the beam may be plugged or otherwise filled after removal of the bracket.
The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
What I claim and desire to secure by Letters Patent is:
1. In combination with a support, an overhang The foot plates permit additional adjustments in form supporting bracket including, an upright flat plate, lateral flanges secured to and extending longitudinally of the plate, attachment means projecting longitudinally from one end of said plate for connecting the same to the support with the flanges of said plate horizontally disposed, a transverse bar secured to the lower portion of the plate end and having its ends projecting laterally beyond said plate, and adjusting screws threaded through the bar for bearing against the support so as to maintain said plate in fixed ad justed positions.
2. In combination with a support, an overhang form supporting bracket including, an upright flat plate, lateral flanges secured to and extending longitudinally of the plate, attachment means projecting longitudinally from one end of said plate for connecting the same to the support with the flanges of said plate horizontally disposed, adjusting means projecting from said plate end for bearing against the support so as to maintain said plate in fixed adjusted positions, the plate being substantially triangular and having an inclined upper edge, the flanges being disposed near the lower edge thereof below the upper inclind edge, and means reinforcing the end portions of said flanges.
