Definitions

  • the present application concerns a form, a system and a method for forming columns, decks and beams of cementatious material such as concrete. More particularly, it is concerned with a forming system which provides adaptation to different lengths and dimensions of upright support columns and beams for building construction, particularly those with poured concrete decks supported by the columns and beams.
  • Such forms have historically been constructed of wood which, when stripped from the cured concrete, is no longer of use.
  • Metal forms, of aluminum and/or steel, have been custom manufactured for a particular building configuration.
  • Other types of forms include tubing made of high strength water resistant paper, such as those sold under the trademark SONOT UBE®. Again, these forms are constructed in aparticular dimension for single use.
  • Other forming panels of metal such as aluminum forming panels including those shown in U.S. Patent Nos. 4,708,315, 4,744,541, 4,976,401 and 4,978,099 have been used to form columns, but these have not produced a flexible, integrated, reusable system for forming concrete columns, beams and slabs.
  • the present invention provides a column and beam system which is adaptable to form columns and beams of different sizes as well as decks which are poured with the beams and columns in a monolithic poured concrete structure. That is to say, the forming system hereof enables the use of forming panels to provide columns and beams of not only their greatest dimension, but also a number of smaller dimensions as well, and is both environmentally and economically superior to custom forming systems because it reduces the number of forming members required because the forming system is adaptable and reusable.
  • the forming system hereof permits the use of column forms, beam and slab forms and associated hardware for columns to be formed in a plurality of configurations, reduces the amount of time required to complete the concrete forming and pouring of the structure, and by minimizing the number of concrete pouring operations, provides a more monolithically poured structure.
  • the system hereof permits the formation of beams, and adjacent decks, which are formed together with the columns in a monolithic pour, or alternatively in sequential concrete pours.
  • the beam forms are complemental to the column forms, so that the beams, columns and an elevated deck can be poured in a monolithic pour.
  • the forming system provides templates for drilling through a face sheet so that the connections can be made a regularly spaced locations. Because the frame of the forming panels include holes which serve as a template, openings are drilled in the face plate only when required and ready for use. and the worker uses the existing holes in the forming panels as a guide. When the openings are drilled, the openings are at regular, preselected intervals.
  • the forming system is more readily assembled in a desired manner by unskilled workers.
  • the openings can be plugged, such mat the forming panels can be readily reused in a forming system reconfigured for a different structure having columns, beams and decks of a different size or configuration..
  • the system of the present invention includes column forming panels which preferably primarily of aluminum and are connected together to provide forms for the columns, with beam forms preferably primarily of aluminum including joist ledgers and sill plates to provide forms for the beams. Transition forms also preferably primarily of aluminum are used to provide connections between the beams and columns, and ceiling forms are connected to and provided intermediate the beam forms in order to receive concrete for forming a deck.
  • the column forms include a face sheet, side, top and bottom rails, and reinforcing members or hats.
  • the hats are provided with a plurality of selectively spaced holes, e.g. 1 " on center. The holes are spaced longitudinally along a back plate of the hats.
  • Holes are also selectively spaced, most preferably in groups which have the holes at the same interval (e.g. 1 "), along the side, bottom and top rails of the column form. These holes may be reinforced with steel, either as steel plates or steel wire positioned adjacent the holes.
  • the hats identified in the accompanying drawing by reference character 8, include upper and lower bolt slot rails and a center groove which is U-shaped with the back plate of the hat forming the bight of the U and opposing panels each presenting opposite ridges extending longitudinally therealong. Most preferably, the bolt slots are of a smaller transverse dimension than the center groove.
  • U shaped collars are welded to the hats and to the side rails and positioned at the ends of the grooves to abut the side rails.
  • These U shaped collars include a pair of opposed arms which extend longitudinally along the groove and a back plate adjacent and preferably secured to the side rail by welding or mechanical fasteners.
  • the U shaped collars including opposed flanges which extend from the arms and are spaced from the back plate so that a collar nut having a rectangular plate and which is internally threaded may be received and held in place by the U shaped collars.
  • the forming panels may include additional U shaped channels also presenting a plurality of selectively spaced holes therealong.
  • the holes in the hats and channels need not extend into the face plate, which is typically of a relatively thin sheet of aluminum. Plugs are provided to close holes when the face plate is drilled to receive fasteners such as pins, tie bars, or the like therethough, but after the pins or tie bars are removed and relocated.
  • the system hereof provides a number of unique advantages over prior column, deck and beam forming systems. These include:
  • the holes which may be stamped or drilled in the hat or other parts of the frame of the forming members provide: a locator to ensure even spacing so that when the forms are coupled together, the holes are aligned with or
  • the holes in the hat provide a drill guide when drilling the face plate; the drilled holes in the face plate are thereby ensured to be in proper alignment; the hats, being of an additional thickness, may also be of steel to provide strength and need not be drilled, but may help to retain plugs which would be readily dislodged if held only in the face plate.
  • the hats include a bolt slot which enables the attachment of a bolt by only insertion of the bolt head and rotation thereof within the slot; this thereby allows attachment of various hardware.
  • it provides a boss against which a backing plate of steel or other metal may be placed so that a pin may thereby be passed through the hole in a side rail and also through a hole the hat, then through the backing plate and a wedge passed through a slit in the pin to hold the adjacent forms in a secure, tight relationship;
  • the provision of the U shaped collar and collar nut reduces the span along which the rail must carry bowing or torsional loads caused by the pressure exerted by the concrete against the face plate of each form.
  • each of the side flanges is normally subject to enhanced torsional loading, particularly where the pins couple adjacent forms.
  • the U shaped collar preferably of an aluminum alloy or steel, welded at the ends of the grooves in the hats, the collar is reinforced at the primary location where the outward and torsional loading is applied, and can be further secured by the use of the collar nuts.
  • the outward and torsional loads are primarily directed within the hat, rather than along the rails between the hats.
  • the provision of uniform hole spacing which is complemental to the side rail provides the ability to assemble the columns in a variety of configurations, for example, at least fourteen configurations, while still preserving the ability to add additional forms to increase the dimensions.
  • This provides not only a great deal of economy over typical column forms which are dimensioned for connection in only a single configuration by reducing inventory, but greatly increases the flexibility of the on-site applications. That is, the forms may be assembled and adapted as site conditions require, without the necessity of delaying in waiting for new column forms or the necessity of building forms of wood on site. Waste is reduced by avoiding the need for single-use forms.
  • the ability to insert plugs ensures that the form is not rendered into scrap merely by drilling through the face plate in one of the preselected locations.
  • the forming panel hereof is most preferably dimensioned common to other forms so that it may be used, if desired, as a wall form.
  • Angle braces are used at the corners and are provided with selectively spaced holes complemental to the holes in the side rails of the forms.
  • the angle braces may be dispensed with when the forms are combined so that the adjacent forms are positioned narrower than the side rails of the first form.
  • box corner forms are preferably provided for use in combination with the adjustable columns and beam ledgers of the system to thereby permit the depth of the beam to be adjusted by movement of the beam ledger forms and/or the sill plate forms without encountering interference with the column forms.
  • the beam it is greatly desirable to standardize the floor to floor height, but to accommodate different beam cross-sectional dimensions.
  • the beam ledger provided with a plurality of selectively spaced holes along its top, bottom and side rails, but also because the beam ledger is preferably provided with at least one perforated interior brace, the holes defining the perforations also being selectively spaced in common (e.g., 1 inch) with the holes in the rails.
  • the beam ledgers are provided with ledger extensions which extend along at least one edge, preferably the top edge, to provide an extended surface and support for receiving ceiling forms thereon.
  • ledger extensions which extend along at least one edge, preferably the top edge, to provide an extended surface and support for receiving ceiling forms thereon.
  • the present system not only permits the designer to adapt the same forms to change the floor to floor height within a building, but also to change the beam and deck thickness and width, and also to provide different deck thicknesses on the same level, to omit a beam or a part of a beam, or to change the top surface of the deck on the same general level.
  • Another advantage of the present invention is that the same forming system can be used and reconfigured not only from one building to the next, but also from one level to the next within the same building, not only with the same arrangement of beams, columns and decks, but with different beam, column and deck sizes, depths and configurations within the building.

Because the present system 100 provides substantial flexibility in the desired depth and width of the beams to be formed, the position of the sill plate form 108 can be moved upwardly and downwardly before coupling the side rails of the sill plate form to lie adjacent the face sheet of the beam ledger form.

  • the wall width of the walls 270 and 272 is preferably substantially the same as the rearwardly extending dimension of the L-shaped ledger extension and thus facilitates attachment of the beam ledger forms, and permits them to be positioned up or down as desired to avoid interference with the column forming panels 102 when assembled as shown in Figs. 1. 2 and 3.

  • the ability to provide a different depth of the beam also allows use of the same column forms, beam ledger forms and box corner forms, as well as the same sill plate forms 108.

That is to say. the sill plate forms 108 may be coupled by pins and wedges or other couplers to the beam ledger forms 106 at a variety of locations enabled by the number of holes 156 in the braces 198 which have a regular interval spacing therebetween.
  • the sill plate forms 108 may thus be located either relatively higher or lower on the beam ledger forms 106 and coupled thereto at the desired location using pins which extend through the side rails of the sill plate forms and the holes 164 in the face plate of the beam ledger forms and the holes 156 in the braces 198.
  • the beam form assemblies 250 and 252 define concrete-receiving regions 282 as channels which receive flowable poured concrete or other cementatious material such that the concrete hardens to a self-sustaining condition to provide beams such as beams 260 and 262.
  • the floor forms may be coupled to the box corner forms and the beam ledger forms so that the elevated deck or floor 264 shown in Fig. 14 is poured contemporaneously with the beam and the columns and thus the top surface of the beams and columns is in fact the top surface also of the floor 264. Only a portion of the resulting floor 264 is shown for clarity.
  • the beam and column system hereof may be used with a variety of other floor forming systems, such as forming systems which enable supporting structure therein, also known in the trade as "waffle floors.” Such systems are shown, for example, in the U.S. Patent Application entitled Apparatus and Method for Forming an Elevated Deck, published under Publication No.
