Definitions

  • a shoring bracket for overhead formwork including a support head engageable with a formwork beam and vertically adjustable by means of a screw jack so as to effect a selective elevation and lowering of the formwork.
  • the bracket also includes a roller associated therewith and positioned so as to receive the formwork beam upon a lowering of the support head whereby a longitudinal rolling of the beam along the bracket can be effected for a removal of the formwork.
  • the instant invention generally relates to shoring or support brackets for formwork or the like, and is more particularly concerned With a unique column mounted bracket which both provides a vertically adjustable support and a means for laterally shifting the formwork for facilitating both a positioning of the formwork and its subsequent removal.
  • Another significant object of the instant invention resides in the provision of a support bracket which can be mounted directly on a structural column, requiring no floor engaged bracing or supports.
  • an important object of the instant invention is to provide a support or shore bracket which is of a highly rigid construction, easily operated, compact and durable, capable of repeated reuse.
  • a bracket including an elongated tubular body within which a screw jack is threadedly mounted for the selective elevation and lowering of a superimposed support head.
  • a support roller mounted on the tubular body, laterally of the top thereof, is a support roller which can selectively receive the formwork beam from the support head so as to enable a lateral shifting of the formwork during the removal thereof.
  • FIGURE 1 is a perspective view illustrating one of the brackets of the instant invention in operative formwork supporting position
  • FIGURE 2 is a perspective view of the bracket
  • FIGURE 3 is a side elevational view of the installed bracket of FIGURE 1;
  • FIGURE 4 is an enlarged cross sectional view taken substantially on a plane passing along line 44 in FIG- URE 3;
  • FIGURE 5 is a view through the upper portion of the bracket, similar to FIGURE 4, with the supporting head lowered so as to engage the support roller with the formwork beam;
  • FIGURE 6 is a transverse cross-sectional view taken 3,504,879 Patented Apr. 7, 1970 substantially on a plane passing along line 6-6 in FIG- URE 4.
  • reference numeral 10 is used to generally designate the shormg or support bracket comprising the instant invention.
  • This bracket 16* includes an elongated tubular body 12 having an internal jack passage 14 extending longitudinally therethrough, this passage 14 being internally threaded for a substantial portion of the length thereof.
  • An elongated screw jack 16 is threadedly mounted within the body passage 14 and of a length so as to project a substantial distance beyond both ends thereof.
  • the lower end of the jack will include an appropriate tool receiving head 18 thereon for engagement by an appropriate wrench or other tool in effecting the desired vertical adjustment of the jack 16.
  • the upper end of the jack 16 rotatably mounts a support head 20 by means of a rigid pin 22 affixed to the support head 20 and depending therefrom into a blind bore 24 defined in the upper portion of the jack 16, the pin 22 of course being rotatably received within the bore 24 so as to enable a rotational adjustment of the support head 20.
  • the support head 20 itself is generally U-shaped, including a fiat base or bight portion 26 and two upstanding edge flanges 28 and 30, the flange 30 being higher than the flange 28 and constituting the outer flange as will be best appreciated from FIGURES 1 and 3.
  • the flange 30 includes a pair of preformed nail holes 32 therethrough for the reception of nails or the like 34 used in temporarily locking the support head 22 to a formwork beam 36.
  • the support head 20 is elongated so as to provide a positive stable seat for the beam 36 to be received therein.
  • the bracket 10 is specifically intended and particularly constructed for mounting on a vertical support structure or member, in most instances a column 38 which comprises a portion of the structure under construction.
  • the tubular body 12 thereof is provided, adjacent the upper and lower ends thereof, with a pair of integral laterally projecting enlarged portions 40 and 42 which not only project laterally from the side of the body 12, when considering the bracket in its mounted position as in FIGURE 1, but also rearwardly thereof so as to provide a pair of rear abutment faces 44 and 46 which engage against the support column 38.
  • These projections or projecting portions 40 and 42 can be additionally rigidified by reinforcing flanges 48 and appropriate diagonal brace plates 50 provided between the rear of the tubular body 12 and that portion of each of the projections 40 and 42 toward the rear thereof.
  • Each of the projections 40 and 42 includes a front to rear bolt passage 52 therethrough with these passages 52 receiving the bracket mounting bolts 54.
  • the bolts 54 assuming a concrete column 38, will preferably be cast into the column 38 itself during the forming thereof. However, appropriate bolts anchored in any manner so as to provide for a rigid clamping of the bracket 10 against the column 38 can be used. For example, assuming steel columns, the bolts 54 can either be bolted directly to the columns or welded thereto.
  • the actual mounting of the bracket 10, noting FIGURES 1 and 3, involves a sliding of the bracket 10 onto the bolts 54 and subsequently tightening appropriate locknuts 56 on the projecting ends of the bolts '54 so as to tightly clamp the bracket 10 against the column face, the upper and lower projecting portions 40 and 42 actually providing for an outward spacing of the main body 12 and support head 20 so as to better accommodate the super. imposed formwork 58 and provide working space for the adjustment of the screw jack 16.
  • the bracket is provided with an elongated roller 60 orientated perpendicularly to the longitudinal extent of the support head in alignment and to one side thereof.
  • the roller 60 is rotatably mounted above the upper end of the body 12 and the associated upper projecting portion by means of a pair of laterally spaced mounting cars 62 rigid with the upper projection 40 and projecting upwardly and outwardly therefrom.
  • the roller is so positioned as to receive the full weight of the formwork beam 36 thereon as the support head 20 is lowered at least until the base or bight portion 26 thereof moves below the upper periphery of the roller 60.
  • the relationship between the roller 60 and the mounting ears 62 therefor is such so as to provide for a free rolling support of the beam 36 on the roller 60 without interference from the ears 62.
  • brackets 10 In actual use, a sufficient number of the brackets 10 will be mounted On support columns so as to accommodate the particular formwork being utilized.
  • the formwork is mounted with the support beams 36 thereof resting within the support heads 20.
  • These support heads 20 may actually be lowered so as to position the beams 36 on the rollers 60 which will allow for a longitudinal adjustment of the formwork.
  • the opposed upright support head flanges 2S and 30 will still be positioned adjacent the opposite sides of the beam 36 so as to act as a stabilizing guide therefor ensuring a proper movement over the corresponding roller 60.
  • the individual bracket jacks 16 are manipulated so as to level or bring the formwork to the desired elevation, whether this be completely horizontal or at a predetermined inclination, within of course the limits of the brackets.
  • the pouring or other forming work is then proceeded with and, when it is time to remove the formwork, the bracket jacks are lowered so as to bring the formwork down and engage the formwork beams 36 with the support rollers 60, after which the entire formwork can be rolled out from under the cast slab or the like.
  • brackets of the instant invention utilized as just described, will be particularly useful in pouring multifloor buildings wherein after a floor is poured, the formwork can be slid or rolled through one open end of the building and, through appropriate overhead derrick means, elevated to be utilized in the formation of the next floor, the formwork being merely slid back into the building on brackets mounted to accommodate the formwork for the forming of the next higher floor.
  • This general system is now utilized in forming multi-story concrete slab buildings, however, the instant invention eliminates the extremely cumbersome floor engaged bracing structure now required to support the overhead formwork, as well as the provision of dollies or the like when it becomes necessary to move the fioor supported conventional formwork.
  • the instant invention by the provision of formwork supporting brackets which mount directly on the adjacent support columns, and which incorporate form moving rollers directly thereon, not only provides a completely clear working area beneath the formwork, but also greatly reduces the actual structural bulk of the formwork and the necessity for providing independent means for propelling the formwork during its removal.
  • a support bracket for formwork used in constructing multi-story concrete buildings comprising a body, means carried by said body for connecting the bracket to a vertical column of a concrete building, a first support head mounted on said body and having a load bearing surface, adjustable means to permit vertical adjustment of said load bearing surface from a first elevated position to a second lowered position to facilitate removal of a load from the load bearing surface, and a second support head mounted on said body and having an anti-friction load bearing surface between said first elevated position and said second lowered position whereby the load on the load bearing surface of the first support head is transferred to the anti-friction load bearing surface of the second support head as a result of said vertical adjustment.
  • a support bracket according to claim 1 further comprising ioller means mounted on said second support head to provide said anti-friction surface.
  • a support bracket according to claim 2 wherein said adjustable means comprises threaded screw means.
