Definitions

  • the present invention relates to a method and apparatus for forming an elevated concrete slab of a building.
  • Known methods of constructing concrete slabs of buildings utilize movable forms which extend from a lower slab up to substantially the bottom surface of a slab section to be formed. The top surfaces of these forms are generally flat.
  • a typical pour of concrete with such forms includes a level generally 8" layer of concrete with reinforcing rods laid throughout. Following completion of the pour and setting of the concrete, the form is collapsed slightly and rolled out from under the freshly poured slab section where it is moved by an overhead crane to a new location where the process is repeated.
  • the form is collapsed slightly and rolled out from under the freshly poured slab section where it is moved by an overhead crane to a new location where the process is repeated.
  • Considering the size of equipment required to move such forms and the size of the forms themselves have been useful only for relatively large construction projects.
  • because of the high cost of labour it has not been hitherto economical to form a concrete slabs with a relatively thin layer of concrete supported at regular intervals by thicker parallel spaced apart concrete beams integral with the thin layer of concrete.
  • the present invention provides a method of forming an elevated concrete slab of a building which includes assembling the supporting structure at a predetermined distance below desired level of the slab section.
  • the method includes laying a plurality of elongated forming members of substantially rectangular cross section in parallel spaced apart relationship on top of the supporting structure.
  • the ends of the members extend between transversely extending forms which are for forming a concrete end structure to be made integral the slab which is used to support the ends of the slab section.
  • Each of the forming members have protruding shelves along its sides parallel to the bottom surface of the forming member. Laying an elongated beam plate on opposed shelves between preselected ones of said forming members results in a beam channel defined by the upper surface of the plate and the opposed sides of the forming members.
  • the method further comprises placing gapping means for spacing the ends of the elongated forming members and the concrete end supporting structures prior to pouring the concrete. Removal of the gapping means leaving gaps between the ends of the forming members and the forms abutting the ends of the forming member enables the ready release of the forming members following setting of the concrete.
  • concrete reinforcing rods supported by stands set across the tops of adjacent spaced apart members and overlying the beam channels hold the rods at a predetermined level above the top of the forming members and substantially parallel thereto.
  • a lower set of concrete reinforcing rods substantially parallel to the beam channels are suspended in the lower portions thereof by ties attached to corresponding respective reinforcing rods supported by the stands.
  • apparatus for forming an elevated concrete slab section of a building which includes a plurality of elongated forming members of substantially rectangular cross section. Along opposite side surfaces of and parallel to each forming member proximate the bottom surface thereof are attached a pair of elongated outward protruding shelves. A plurality of elongated beam plates for placement on opposed shelves of adjacent spaced apart forming members in combination with opposed side surfaces of the forming members define a beam channel.
  • a plurality of elongated bridging plates for placement on top of preselected adjacent spaced apart forming members define a portion of the bottom surface of a concrete slab section which in combination with the top surfaces of the forming members of the beam channels define the form for the bottom of a slab section on which concrete is poured.
  • Reinforcing rods are supported intermediate the beam channels at preselected distances above corresponding associated beam plates.
  • Destructible means are used to separate the ends of said members from adjacent transversely extending forms for a concrete end support structure.
  • the destructible means are plates of cellular material which are sufficiently soft so that they can be manually separated into small pieces and removed.
  • the assembly of elongated forming members, beam plates and bridging plates can easily be managed by two workmen without the need for overhead cranes and the like.
  • the width of the beam plates and spacers for placement between those forming members not enclosing beam plates can be made to automatically position forming elements so that the distance between the concrete beams formed in the beam channels and the width and depth thereof are as required.
  • V-shaped metal stands with notches to support the upper set of reinforcing rods a preselected distance above the tops of the forming members also provides a surface for the support of rails which may be used as screed surfaces for levelling the freshly poured concrete. Finally, there is also a corresponding reduction in the amount of heavy equipment required and in the number of personnel to manage the forms.
  • Figure 1 illustrates the assembled structure used to define a section of a concrete slab.
  • a pair of beams which define an assembly supporting structure are held at a preselected distance above a ground level 11 by a plurality of adjustable supports 12.
  • Traversing the supporting structure are a plurality of parallel spaced apart elongated forming members 14 which are rectangular in cross section.
  • the forming members 14 are constructed of plywood sheets joined by either elongated aluminum extrusions 26 as shown in Figure 7 or by elongated braces 32 as shown in Figure 8.
  • Each forming member 14 includes an outward projecting shelf or ledge 24a, 24b running along the entire length of each side of the forming member 14.
  • a plurality of beam plates 20 are supported by opposed spaced apart shelves 24 of associated forming members 14 the spacing between which is equal to the width of the beam plate 20.
  • the beam plates 20 in combination with the sides 40, 42 of the forming members 14 define a beam channel 38.
  • the ends of those adjacent, spaced apart forming members 14 which do not enclose beam plates are held apart at a preselected distance by spacers 15.
  • forms 18 for defining a concrete end support structure.
  • Figure 1 illustrates such a structure as comprising a wall 16 whose top surface is at substantially the same level as the bottom surface of beam channels 38 formed by the two sides 40 and 42 of the spaced apart forming elements 14 and the top surface of beam plate 20.
  • Each of the beam channels 38 communicates with the interior of the forms 18 which form the concrete end support structure (not shown).
  • a wall 16 as shown in Figure 1 there may be a large concrete beam 56 as shown in Figure 3 supported at regular intervals therealong from the floor 11 by posts (not shown).
  • a plurality of disposable metal stands 34 formed by bending sheet metal into a V-shape and forming a notch 36 midway along the bent portion are placed across the beam channel 38 at regular intervals therealong such that each stand is supported at its ends by respective associated forming members 14.
  • An elongated strip 37 along the outer edge of each wing 35 of the stand 34 is bent so that the two strips 37 on each stand 34 lie in a plane perpendicular to a notional plane bisecting the angle between the wings 35.
  • a small hole 39 is drilled at one corner of each strip 37 the holes being at diagonally opposite corners of the stand 34.
  • the stands 34 are fabricated so that they hold a reinforcing rod 46 at a preselected level above the forming members 14.
  • Further reinforcement is provided by laying mesh or reinforcing bar 62 over top of the upper set of reinforcing rods 46.
  • a lower set of reinforcing rods 48 is suspended from the upper set 46 by a plurality of ties or wire hooks 44 which grasp both the upper and lower rods 46 and 48. The weight of the reinforcing rods 46 and 48 is sufficient to prevent any movement of the stands 34 once the structure is assembled.
  • Figure 2 illustrates a sectional view of the assembly taken along line 2-2 of Figure 1.
  • strips of cellular material such as styrofoam 52 are positioned between the ends 50 of each forming member 14 and abutting portions 54 of the forms 18 of the end support structure.
  • Figure 4 shows a method of joining the ends of two adjacent slab forming assemblies.
  • a platform 70 is supported by a pair of beams 10 which, in turn, are supported by adjustable supports 12.
  • the ends of forming members 14 are held at a desired distance above the platform 70 by blocks 72 which also support the cellular material 52 and portion 54 of the forms for the end structure.
  • Figure 5 shows an alternative end wall structure which would be used for prefabricated walls 76 in which the top 82 of wall 76 has a plurality of beam notches 78 coinciding with the beam channels 38 of the slab forming assembly.
  • the end 50 of each forming member 14 has fastened with staples 84 around its periphery as shown in detail in Figure 6 a strip of cardboard 74 with approximately a 1 inch overlap which abuts the wall 76 ( Figure 5).
  • the method of forming an elevated slab section includes positioning the pair of beams 10 a preselected distance above the ground level 11 or below a top surface of the concrete slab to be formed by adjusting the adjustable supports 12. With the beams 10 in position the forming members 14, beam plates 20 and bridging plates 22 are laid transversely to the beams 10 with beam channels 38 formed at regular intervals usually with beam plates 20 alternating with bridging plates 22. Small finishing nails driven through the bridging plates 22 into the forming member 14 may be used to hold the bridging plates 22 in position.
  • reinforcing rods 46 held by notched metal stands 34 are supported over the beam channels 38 by the tops of opposed forming members 14 along the entire length of the channel and extending therebeyond into the area within the forms 18 of the end support structure.
  • the stands are fixed in position by two small finishing nails nailed through holes 39 into the forming members 14.
  • a lower set of reinforcing rods 48 are suspended from each of the upper rods 46 by a plurality of hooks 44.
  • Strips of cellular material 52 such as styrofoam are stapled to portions 54 of the forms 18 so that when in situ each end edge of end 50 of the forming member 14 is covered by a strip of the cellular material 52.
  • the portion 54 of the forms 18 are opened at each beam channel 38 so that the latter communicates with the interior of the forms 18 and so that the reinforcing rods 46 and 48 lying along the beam channel 38 extend within the interior of the forms 18.
  • Wire mesh or reinforcing rod 62 is laid over top of the assembled structure as seen in Figures 1 and 2.
  • the upper reinforcing rods 46 are used to support a pair of rails 60 whose top surface is at the desired level of the top surface of the slab section to be formed.
  • the rails 60 are utilized to screed the top surface of concrete which is poured over the structure through the wire mesh. Concrete is also poured at the same time in the forms 18 of the end support structure.
  • the forming members 14 may be achieved by simply removing the cellular material 52 from each end of the forming members 14 thereby leaving a gap and permitting release of the forming members from concrete which contacts the upper surface and in some cases one side surface thereof.
  • the bridging plates 22 and beam plates 20 are also removed. Once completion of a given slab section is achieved, the forming members 14 bridging plates 22 and beam plates 20 can all be easily removed for use on an additional slab section. However, the metal stands 34 are permanently incorporated into the concrete of the slab section.
