Definitions

  • This invention relates generally to the field of forms constructed to be filled with concrete or other flowable and settable materials, and more particularly to a pre-fabricated concrete wall forming system that includes at least one wall formed of fabric.
  • Wall forms have been in existence since Roman times. While significant changes in materials have occurred over the years, the basic principle remains the same: create a cavity using spaced, rigid flat surfaces into which a flowable and settable building material is deposited and remove the surfaces after the material has set to leave the wall in place.
  • the rigid surfaces were made from hand cut lumber.
  • steel, plywood or even rigid plastic are used. Bracing to hold the forms together were made of rope or wood in the past. Now they are made from steel or plastic rods.
  • United States Patent No. 4,154,061 to Umemoto discloses a fabric form for concrete formed from reinforced fabric sheets.
  • the resulting fabric forms are suitable for low footings, but the forms are insufficiently rigid to permit formation of rigid, vertically upstanding foundation walls. Concrete when constrained in vertical fabric forms tends to flow under gravity to cause outward bulging of the fabric walls with an vertically extending S curve such that the fabric form fails to maintain the desired straight vertical wall shape .
  • Co-inventor, Richard N. Fearn, of the present invention is the owner of United States Patent Nos. 5,224,321 and 5,794,393, the disclosures of which are incorporated herein by reference.
  • Patent Cooperation Treaty International application No. PCT/CA98/00619 owned by inventor Fearn discloses a fabric form system designed for the efficient and inexpensive production of footings using an external support structure for the fabric.
  • At least one flexible, fabric surface spaced from the rigid surface to define a container with side walls; and a plurality of flexible links extending between the side walls of the container to position the at least one flexible, fabric surface with respect to the rigid surface.
  • the present invention provides a wall form assembly comprising:
  • At least one flexible membrane interconnected with the structural surface by a plurality of flexible links to position the at least one flexible membrane with respect to the structural surface to define a space therebetween to receive a flowable and settable material.
  • the rigid and fabric surfaces are left in place on the formed wall so that stripping is not required.
  • the . rigid surface is preferably a rigid insulation panel and the fabric surface is preferably treated to be water impermeable so subsequent insulation and water proofing of the formed wall are unnecessary.
  • Figure 2 is a section view through a completed foundation wall and the wall form assembly according to an embodiment of the present invention, and is as seen on line 2-2 of Figure 2a;
  • Figure 4 is a detail view of an embodiment of the present invention that uses a rigid insulation panel as the rigid surface;
  • Figure 5 is a detail view showing a preferred manner in which the links are received in cavities in the rigid insulation panel
  • Figure 8 is a detail view of a further embodiment formed from an outer flexible, fabric layer, a intermediate rigid insulation layer and an outer rigid layer with links extending between the outer layers through the intermediate layer;
  • Figure 11 is a detail view of a clip used with the wall form assembly of the present invention to hold reinforcing bar.
  • FIG. 1 there is shown a conventional prior art wall form structure 10 positioned atop an existing footing 12.
  • the wall form structure includes a series of plywood or steel panels 14 that are supported by an external framework 16 to define a pair of spaced, rigid planar surfaces with a cavity 18 therebetween to received fluent concrete.
  • the spacing of the panels 14 is maintained by rigid steel or plastic rods 20 that extend between the panels.
  • Structural surface 32 must be sufficiently rigid and of appropriate strength to support the pressure of the concrete while setting and the tensile loads generated by links 36 as flexible membrane 34 acts to confine the concrete at the opposite side of the form assembly from structural surface 32.
  • structural or rigid surface 32 can be formed from panels of plywood as previously mentioned.
  • surface 32 can be formed from panels of rigid insulation material. This technique has the advantage that walls are pre-formed with insulation and a separate application of insulation of wall formation is unnecessary.
  • the rigid insulation material can be conventional extruded polystyrene (XPS) or expanded polystyrene (EPS) panels.
  • Flexible membrane 34 can be semi-rigid.
  • flexible membrane 34 can be formed from wire mesh with a covering membrane.
  • flexible membrane 34 can be a plastic sheet. It is sufficient that flexible membrane 34 be a relatively light weight material that is capable of withstanding the tensile forces generated by the flowable concrete.
  • Structural surface 32 and flexible membrane 34 are preferably supplied in sheets or panels of uniform dimensions to allow form walls of a desired length to be assembled. For example, panels dimensioned to be 4 feet wide by 8 feet high provide components parts that are conveniently handled for efficient assembly. Rigid structural surfaces 32 can be joined together in a standard manner such as nailing, gluing or interlocking of tongue and groove connectors 98 formed in the side edges (see Figure 10) .
  • brace flexible membrane 34 it is necessary to brace flexible membrane 34 to minimize bulging of the membrane and ensure sealing of the upper and lower edges.
  • this is achieved by constructing a framework adjacent the flexible membrane comprising a lower kicker 37 and an upper whaler 39 to which the flexible membrane is stapled at 47.
  • a series of spaced vertical braces 41 extend between the kicker and whaler.
  • the kicker, whaler and braces are formed from 2x4 lumber cut to size.
  • Flexible membrane 34 is preferably impermeable to water to provide waterproofing for the finished wall.
  • a waterproof coating 48 can be applied to prevent water access.
  • a water drainage layer 49 is provided adjacent the waterproof coating to move water away from the constructed wall .
  • flexible membrane 34 and rigid structural surface 32 define a container with side walls to confine concrete in a flowable state.
  • Membrane 34 and rigid surface 32 are joined together by a plurality of flexible links 36 extending between the side walls of the container that serve to position the flexible membrane with respect to the anchored rigid structural surface.
  • flexible links 36 extend between the side walls of the container in a regular pattern on about 3 inch centres (see Figure 2a) .
  • the length of the links will vary depending on the thickness of the concrete wall being poured. For example, flexible links 36 that are 8 inches long are used to form a wall that is of average thickness.
  • each link 36 comprises a tie 48 woven or sewn into the material.
  • each tie 48 comprises a drop stitch defining a loop of material extending from the warp or weft of surface 50.
  • the tie is preferably anchored to structural surface 32.
  • Figures 4 to 6 show various techniques by which ties 48 are connected to a rigid insulation panel 54.
  • holes 56 are formed through the insulation panel aligned with ties 48.
  • the ties are inserted through holes 56 such that their distal ends 58 protrude from the opposite side of the insulation panel.
  • the ties are glued in place using an appropriate polymer glue.
  • cavities 60 are formed in the rigid insulation to receive the distal ends of the ties. Cavities 60 are filled with polymer glue 62 to anchor the tie ends to the rigid insulation.
  • Figure 7 illustrates a still further anchoring technique for connecting ties 48 to the structural surface 32.
  • structural surface 32 can be a plywood panel or a rigid insulation panel .
  • Hook members 64 are mounted to the structural surface 32 by gluing, nailing, stapling or the like. Hook members 64 are preferably injection moulded plastic pieces.
  • Each hook members 64 is inserted through the loop of a tie 48 to interconnect flexible woven surface 50 with rigid structural surface 32. It will be appreciated by a person skilled in the art that alternative techniques are possible for anchoring flexible links 36 to flexible membrane 34 and rigid structural surface 32. It is sufficient that flexible links 36 be securely anchored at each surface in order to be able to resist tensile force resulting from introduction of the flowable concrete between the surf ces .
  • Ties used with a woven fabric flexible surface will preferably be formed from the same fabric material as the woven surface. It is also possible to make the ties from flexible plastic that is bonded at each end to one of structural surface 32 and flexible membrane 34.
  • the wall form system illustrated in Figure 7 is similar to a conventional form as illustrated in Figure 1 except for the significant modification that one rigid surface is replaced with a flexible membrane joined to the remaining rigid surface by an array of flexible links.
  • One advantage of such an arrangement is that the wall form of the present invention is significantly lighter in weight and is therefore easier to manipulate and install. Material costs are also reduced. There is less labour involved as only the plywood surface needs to be stripped once the concrete is set . The flexible membrane remains in place against one side of the finished wall to act as a damp proofing barrier.
  • the wall form system illustrated in Figure 7 offers the additional advantage that the rigid insulation panel performs a dual function as a side wall co-operating with the flexible membrane to contain the flowable and an insulating member. Once the concrete is set, no stripping is required as the rigid insulation panel on one side and the flexible member on the opposite side of the wall remain in place.
  • the rigid insulation panel and flexible membrane combination provide a light weight modular wall form assembly that enjoys reduced shipping, installation and handling costs.
  • the wall form assembly of the present invention can be set up in alternative arrangements from that illustrated in Figure 7.
  • Figure 8 shows an arrangement in which a rigid structural surface 32 (a plywood panel or a rigid insulation panel) defines one side wall of the form.
  • An intermediate rigid surface 70 preferably formed from a rigid insulation panel defines a middle layer, and an outer flexible membrane 34 ( a woven fabric surface) defines the other side wall of the form.
  • flexible links 36 extend between the outer rigid structural surface 32 and the outer flexible membrane 34 through openings 72 formed in the intermediate rigid surface 70.
  • Figure 9 illustrates a further embodiment of the wall form assembly of the present invention in which a first outer flexible membrane 75 (a woven fabric surface) defines one side wall of the form.
  • a first outer flexible membrane 75 (a woven fabric surface) defines one side wall of the form.
  • an intermediate rigid surface 78 comprising a rigid insulation panel that defines a middle layer and a second outer flexible membrane 80 that defines the other side wall of the container.
  • Flexible links in the form of loop ties 82 extend between the first and second outer flexible membranes through openings formed in the intermediate insulation panel.
  • This wall form assembly provides a light weight structure in which the middle insulation layer is braced to support the entire form. Once the concrete sets, the internal middle insulation layer is protected from the environment by a layer of concrete and the outermost flexible membranes which remain in place.
  • the middle insulation panel 78 can be positioned essentially equidistantly from the first and second outer flexible membranes 75 and 80. In this configuration, when concrete is poured, the insulation is sandwiched between two thicknesses of concrete.
  • the intermediate insulation panel 78 can be positioned to contact one of the first and second outer flexible fabric surfaces to create a single internal concrete layer sandwiched between a woven fabric layer 75 on one side and an insulation panel 78 and a woven fabric layer 80 on the opposite side.
  • This arrangement is preferred as it provides a single concrete wall that is protected from the environment.
  • the use of two outer flexible membranes provides the best possible anchoring for the ends of links 82.
  • Figure 10 shows a preferred tensioning arrangement installable at changes in direction of the wall form assembly to ensure that corners are properly shaped.
  • Figure 10 is a perspective view of a corner in a wall form 30 constructed according to the present invention with a rigid structural surface 32 and a flexible membrane 34 defining the outer form walls joined by a plurality of flexible links 36.

  • Tensioning member 85 is positionable adjacent a corner region 89 and is mounted to rigid structural surface 32 via a mounting bracket in the form of angle bracket 88. The angular separation of the surfaces of angle bracket 88 is selected to corresponding to the angle of the corner region.
  • Tensioning member 85 includes a protruding angled flange 90 that extends across interior 38 from rigid structural surface 32 for attachment to flexible membrane 34 to support and tension the membrane through the change in direction.
  • the flexible membrane is stapled or glued along edge 92 of flange 90 which defines the corner edge of the form assembly.
  • Protruding flange 90 is formed with a plurality of openings 95 therethrough to allow for the free passage of flowable concrete around the corner.
  • FIG 11 is a top plan view illustrating a clip 100 mountable between panels of rigid insulation 32 to hold vertically aligned reinforcing bar 102 in place within interior 38 of the wall form.
