Definitions

  • This invention relates to concrete forming structures and panels used in such structures.
  • United States patent 3,130,470 and Canadian patent 605,806 disclose the use of steel members in forming the framework
  • United States patent 3,862,737 discloses the use of aluminum in forming the structural components of the frame.
  • Aluminum is advantageous, because its lightweight usually provides a more readily manageable wall forming panel. However, due to the lesser strength characteristics of aluminum, adaptations are required in forming the prefabricated panel frames.
  • the preformed panels are fabricated in a manner such that they are interconnectable and in situations where the panels are used in forming walls, well known tie members may be used to maintain the desired spacing between opposing wall panels when a wall is being poured.
  • Such an arrangement is shown in Canadian patent 605,806, where prefabricated panels of various shapes are interconnected to provide opposing wall arrangements and between which concrete is poured.
  • the tie members as normally connected to an open cage device, extend between wall arrangement inserts to which horizontally laid panels are connected.
  • a similar approach to a forming wall arrangement is provided by many companies, such as, Peri-Werk Artur Schworer KG of WeiBenhorn, West Germany. This company supplies prefabricated panels where inserts, which are connectable to the panels, provide the wall arrangements.
  • the inserts may oppose one another and the ties, as connected to the inserts, maintain the desired spacing while concrete is poured between the forms.
  • the inserts are supported by the use of reinforcing members (walers), whereby the insert arrangement spaces the walers from the interconnected panels. This results in a system which provides limited flexibility in shortwall constructions, because the walers are spaced from the panels, thus requiring inserts at every panel interconnection.
  • the framework components are commonly welded together to provide a resultant integral structure. Should any components of the framework become damaged or fractured, it is usually necessary to scrap the entire panel, particularly if made of aluminum, because welding or repair of the aluminum components is very difficult.
  • the pretensioning arrangement provides for an interconnection of one siderail member to the other, where the cross-bars are clamped between the siderails as the pretensioning devices are tightened to apply an outward biased pressure on the cross-members to reinforce the cross-members against the load applied to the panel when used in concrete wall forming arrangements.
  • Such an arrangement is difficult to implement in the field, because the workmen do not usually have devices which could determine the necessaryy torque to be provided on each end of the pretensioning device to provide the correct tension on each cross-member.
  • the use of such pretensioning devices substantially hinder the assembly of the panel, because all pretensioning devices, as located in the respective cross-bars, must be simultaneously placed through the holes of the siderails which is very difficult to achieve manually.
  • the pretensioning device With the cross-bar having its ends free, the pretensioning device becomes critical in that the cross-bar with free member ends has a significantly higher degree of flexibility, as compared to a cross-bar which is fixed to the siderails such as in the past by welding of the cross-member end portions to the siderails.
  • the panel can bow, due to the greater deflection in the cross-bars, during the pouring operation and result in a poor wall configuration for the set concrete. Therefore, this pretensioned cross-bar arrangement for panels, even though it permits disassembly, does not provide a panel arrangement which may be readily reassembled and which may be consistently relied upon from a load supporting standpoint when used in the field.
  • the panel framework and wall arrangements overcome a number of the above problems in the panels and may be used in a way to provide greater flexibility in making concrete forming structures in pouring concrete floors and walls.
  • the panel metal framework for supporting panel sheeting used in concrete forming structures comprises, according to this invention, a perimeter frame of spaced parallel siderails and endcap rails with a plurality of spaced rigid cross-members within the frame.
  • the endcap rails and cross-members are mechanically secured to the siderails.
  • the cross-members having their end portions fixedly mechanically secured to the opposing siderails are of sufficient number and each of sufficient structural strength and stiffness to support concrete loads exerted on panel sheeting when affixed to the framework and when used in forming concrete.
  • the mechanical connection of the cross-members to the siderails is such that, upon removal of fasteners used in making the connection, the connection is not destroyed. Thus in situations where complete disassembly of the panel arrangement is required, the reused components may be readily refastened into the framework.
  • the mechanical connection is accomplished by means providing for a fixed mechanical connection of an end portion of each cross-member to the corresponding siderail.
  • the means may be provided on either the siderail or the cross-member.
  • connection means is provided on the cross-member end portion, individual damaged cross-members may be removed from the framework and replaced without disassembly of the framework, or cross-members may be simply removed from the framework when the additional support is not required, or cross-members may be added in situations where additional support in the panel is required for a particular use in concrete forming.
  • connection means may be provided internally of the cross-members, so as to protect the fasteners from concrete which may be splashed on the panels during the pouring and also eliminate recesses and the like on the cross-members which may fill with the concrete and when set, add additional weight to the panels.
  • connection means internally of the cross-members
  • mechanical fasteners are used which extend through the siderails and, as received by the internal connection means, draw the end portions of the cross-members against the siderails to provide for a secure fixed connection of the framework components.
  • the cross-members may be formed from extruded aluminum, where the section for the aluminum cross-members is such to provide the necessary strength in supporting the panel sheeting when used in confining poured concrete.
  • each wall arrangement has a plurality of wall form panels and tie member panels.
  • the wall form panels are connectable to one another and to the tie member panels.
  • Each of the wall form panels and strong back panels has a perimeter framework of siderails and interconnecting endcap rails, all of which are of the same depth to define, when the panels are interconnected, a substantially planar frontwall face with the rear edges of the perimeter rails all lying in substantially the same plane, which is parallel to the planar front face.
  • the thus formed opposing wall arrangements are held in a predetermined spaced apart relationship by tie members when concrete is poured between the wall arrangements.
  • Each tie member spans the opposing tie member panels and extends through and outwardly of each panel.
  • the tie members are located along at least one level of the wall arrangement.
  • Horizontal load gathering means may be used where the tie members extend through the load gathering means.
  • Means is provided for engaging the outwardly extending tie member portions and is adapted to clamp the load gathering means at every tie member on the same level against the coplanar panel rear edges to reinforce the wall arrangement and maintain substantially planar frontwall face.
  • a tie plate may be used through which the tie member extends and means is provided for engaging the tie member portions extending outwardly beyong the tie plates to maintain a desired spacing between the tie plates as they contact the exterior of the wall arrangements.
  • Such tie plates each comprise a base portion for spanning the outer panel edges adjacent the tie member panel edges and has means for restraining the outer panel edges from lateral movement relative to panel edge length to enhance structural integrity of the interconnection of the panels.
  • the rear portions of the rail edges may be adapted to have fastening devices securable thereto.
  • the front face of the framework is adapted to have a panel sheeting affixed thereto.
  • the rear edges of the panel rails are adapted to provide in an assembled form structure of a plurality of interconnected panels, a plurality of opposing spaced ledge portions which define an elongate slot.
  • Fastener means is insertable through the slot and is adapted to seat on the opposing ledge portions to provide for the mechanical fastening of elements to the rear edges of the panel rails.
  • FIG. 1 a concrete forming structure for use in forming a wall is shown. It is appreciated, however, that the panels, according to this invention as used in this arrangement for forming the wall, may also be readily used in forming concrete floors, as supported by appropriate shoring structure.
  • the concrete forming structure 10 of Figure 1 for forming a concrete wall 12 is made up of spaced-apart opposing wall arrangements 14 and 16. The opposing wall arrangements are tied together in their spaced-apart arrangement with tie rods 18, which are commonly used in the trade and tied into the walls by way of a tie plate clamping device 20.
  • Each wall arrangement 14 and 16 consists of a plurality of wall form panels 22 which are interconnected by interposed tie member panels, or what could be considered as strong back panels 24.
  • the wall arrangements are ordered so that the panels 22 oppose one another and tie member panels 24 oppose one another. This enables the use of ties 18 to bridge opposing tie member panels 24 and, with panels 22 interconnected to the tie member panels 24, the load exerted on the panels by concrete poured into the cavity between the panel arrangements is transferred to the ties by way of the tie plate clamps 20.
  • aligners in the form of a beam 26 and a base plate 28 may be used to align the interconnected panels and strong backs so as to provide parallel face portions as generally designated at 30 to define the desired cavity into which concrete may be poured to provide smooth parallel wall exterior surfaces.
  • the aligner beams 26 may be bolted to the rear faces of the rails of the panels and strong backs by use of plates 32 bolted to panel rails, which grip the ledge of the beam to clamp the beam against the rear edges of the rails so that the panels become aligned, due to the tie member panels or strong backs and wall form panels all being of the same depth as shown.
  • connectors 34 are shown.
  • connectors 34 may be used to interconnect the panels, as stacked one upon the other, by use of the apertures 36 as shown in the top and bottom portions of each panel.
  • Each panel 22 consists of spaced-apart siderails 38 which are interconnected at their ends by endcap rails 40 and a plurality of cross-members intermediate the endcap rails 40 are spaced apart as shown at 42.
  • the endcaps 40 and the cross-members 42 are all mechanically fastened to the siderails 38.
  • the components can be assembled in the field by use of appropriate mechanical fasteners. During use of the panels, any damage to individual cross-members 42, siderails 38 or endcaps 40 may be repaired by simply disassembling partially or totally the panel framework to permit replacement.
  • the arrangement may also be adapted to permit addition or removal of cross-members 42 from the frame in situations when it is desired to either strengthen the panel or, in view of a subsequent use, remove appropriate cross-members when less strength in the panel is required.
  • cross-members which will be reused, may remain on the plywood facing when it is necessary to remove the plywood facing to repair the panel.
  • the reused cross-members and replaced cross-members may be refastened to the siderails.
  • the framework is such that the interconnection of the cross-members to siderails with endcaps provides a supporting surface against which a panel sheeting, forming the face 30, may be affixed.
  • Such panel sheeting may be in the form of commonly used plywood, or steel, aluminum, or fibreglass sheet to mention only a few.
  • the tie member panels strong backs 24 are constructed in a similar manner, where the framework for the strong back comprises siderails 44 and endcap rails 46 with interconnecting cross-members 48.
  • the cross-members 48 are adapted so as to permit the ties 18 to pass therethrough, which is shown and described in more detail with respect to Figure 4.
  • the siderails 38 of panel 22 include apertures 36 which are also provided in the endcaps 40.
  • apertures 36 are provided.
  • the apertures in the siderails of the strong back and wall panels are positioned so as to be in register when a strong back 24 is abutted against a panel 22.
  • the connectors 34 may be positioned through the apertures 36 and moved into position to clamp the siderails of the wall form panel and strong back tightly together.
  • the siderails for each panel are the same configuration and the endcap rails for each panel are the same configuration and all are of equal depth.
  • the mechanical interconnection of the cross-members 42 and 48 and the endcaps 40 and 46 to the siderails 38 or 44 are all done in the same manner.
  • the wall form panel 22 has its siderail 38 connected to the endcap rail 40 by use of an angle bracket 50.
  • the endcap rail 40 is different in cross-section to the siderail 38 with regard to the prov-ision of a complete bolt slot arrangement 52 on siderail 38 which is only partially provided on the endcap rail 40.
  • a bolt 53 as adapted for use with the bolt slot 52, has a specially shaped head 55 which permits its insertion into the bolt slot and can then be rotated 90 degrees in the direction of arrow 57 to cause the innerface of the bolt head 59 to seat within the bolt slot 52.
  • a square shaped shoulder 61 is provided on the specially shaped bolt 53 to abut the edges of the bolt slot to prevent turning of the bolt when a nut or other device is secured to the bolt in attaching elements to the rear face of the panels.
  • the bolt slot 52 has outwardly extending opposing spaced ledges 63 and 65. Such ledges define along their edge portions 67 the elongate bolt slot generally designated 69.
  • the innerface 59 of the bolt head rest on the abutments 71 of the ledges 63 and 65 to retain the bolt in the slot when elements are fastened to the bolt.
  • the shape for the bolt slot 52 may be so dimensioned to receive a hexagon nut, such that ordinary bolts may be threaded into the hexagon nut as retained behind the abutment faces 71 of the ledges 63 and 65.
  • the bolt slot ledge portions on the rail rear edges also provide the additional material required to give the desired moment of inertia in the aluminum rails to withstand the loads to be supported by the rails.
  • This bolt slot arrangement is particularly useful when clamping alignment beams, such as alignment beam 26 shown in Figure 1, where the plate portions 32 clamp an edge of the alignment beam 26 against the planar rear face of the wall arrangement.
  • other elements may be secured to the rear portions of the panel rails, such as wall brace arrangements, wind brace arrangements, catwalk brackets, devices for ensuring a vertical orientation for the wall arrangements, tie plates to the rear panel edges, reinforcing members or load gathering members, namely walers, and other elements which may be desirably connected to the rear faces of the panels.
  • endcap rails 40 which include only a portion of the bolt slot, it can be seen that endcap rail 40 has a ledge portion 41 with an abutment 43.
  • the opposing endcap rails When panels are interconnected by abutting the endcap rails of the panels, then the opposing endcap rails define between the opposing ledges 41 a bolt slot along the abutment edges 43 of the joined endcap rails.
  • Sufficiently large walers may be secured to the panel rear edges to reinforce the modular wall form arrangement to an extent which forms a gang wall form unit. This so formed gang wall form unit may be hoisted by a crane and moved to another location to pour another wall.
  • a butt type interconnection of endcap rail 40 to siderail 38 is provided.
  • the endcap rail 40 overlaps the siderail 38, as shown in Figure 2, where interfering portions of siderail and endcap rail interior are cut away to provide for proper interfit.
  • Such interfitting of siderail to end rail connection is completed by way of the angle bracket 50, where self-tapping screws 54 are used to extend through apertures 56 in siderail and endcap rails and engage the bracket apertures 58 to form a tight fixed interconnection of siderail to endcap rail.
  • cross-members 42 are provided intermediate the endcap rails of the thus formed perimeter frame.
  • the cross-members 42 are directly fastened to the siderails 38 against its planar interior face portion 60.
  • the cross-member 42 has an end portion 62 which presents a planar face generally designated 64, which mates and abuts the planar face 60 of the siderail 38.
  • a means is provided for making the mechanical connection in combination with the use of mechanical fasteners.
  • such means is in the form of portions on the cross-member 42 which cooperate with the mechanical fasteners 66 in the form of self-tapping screws to mechanically connect and tightly draw the planar face portion 64 of the cross-member 42 against the planar face 60 of siderail 38.
  • Such means for cooperating with the fastener 66 is in the form of an arcuate channel 68 provided on the interior surfaces of the cross-member 42.
  • the arcuate channels 68 are appropriately dimensioned so that the self-tapping screws 66 are firmly screwed into the openings defined at the ends of the arcuate channel 68.
  • the cooperation of the arcuate channel 68 with the fastener 66 is such that the fastener 66 may be removed from the channels to permit removal and replacement of one or more of the cross-members 42, which may have become damaged in use. Alternatively, should it be required to replace a siderail 38 due to damage, the fasteners 66 are removed from each cross-member end 62 to permit replacement of a siderail 38. Because of the cooperation of the arcuate channel 68 with the fastener 66 and removal therefrom avoids damaging the arcuate channel 68, such cross-members 48 may be reused where new or the same fasteners 66 are used to reconnect the siderail 38 to the cross-member 42 which are reused in the reassembly.
  • the siderail 38 and endcap rails 40 include on their interior surface, ledges 70. Such ledges are spaced from the outer face portion 72 and 74 of the endcap rail 40 and siderail 38 to accommodate the thickness of the panel sheeting material 76.
  • the panel sheeting material is plywood and is placed against the ledges 70, where the face of the plywood panel 76 is coplanar with the faces defined by portions 72 and 74 of the endcap and siderails.
  • the panel 76 is secured to the frame ledges by fasteners, such as woodscrews 78 which extend through apertures 80 in the ledges.
  • the woodscrews 78 are of a depth less than the combined thickness of the ledge 70 and the plywood 76, so that the screw does not project through the plywood face.
  • the primary force is against the face of the plywood panel 76 as it confines wet concrete poured against the face.
  • Such force on the panel is taken up by the perimeter frame and the cross-members 42.
  • the cross-members 42 are provided with flanges 80, which are integral with the sides 82 and 84 of the cross-member.
  • the sides 82 and 84 converge towards one another and are interconnected at their narrowest spacing by transverse wall 86.
  • the height dimension of the cross-member 42 from the underside of its flange 80 to the upper surface of transverse wall 86 is such to fit within the spacing between the upper surface of ledge 70 and the underside 88 of bolt slot arrangement 52.
  • the cross-members 42 have fasteners 90 which are woodscrews and which extend through apertures 92 and flanges 80 and are screwed into the plywood facing 76. This secures the relationship of the cross-member flanges 80 to the plywood face to take up the load when the panel is in use.
  • the force on the panel 76 attempts to push the cross-members 42 away from the ledge area 70 of the perimeter frame. This places the fasteners 66 in shear which is the most effective use of the fasteners in resisting such forces.
  • the wall portion 86 as it fits snugly beneath the bolt slot arrangement 52 and contacts its underside 88, enhances the resistance to the cross-member being pushed transversely from the siderail.
  • the cross-members 42 and the frames may be made of various metals, such as steel which has high strength properties, or may be made of aluminum or magnesium alloys.
  • the siderails and cross-members 42 are formed of aluminum alloy, thus the structures may be extruded.
  • the trapazoidal shape, defined in part by the cross-member section 42 has converging sidewalls 82 and 84 which provides a strong load supporting member.
  • ridges 98 may be extruded which bite into the panel face 76.
  • the purpose of these ridges 98 is to prevent concrete, which has just been poured, from running under the flanges and gathering in the interior of the cross-member 42 as the panel abuts the flanges 80.
  • Figure 4 shows the assembly of the tie member or strong back panel 24.
  • the strong back panel has endcap rails 46 with siderails 44.
  • the corners of the frame for the strong back 44 are mechanically interconnected in a manner similar to that of the wall form panel of Figure 3.
  • Mechanical fasteners, in the form of self-tapping screws 100, are screwed through the siderail and endcap rails and into the bracket shown in dot at 102.
  • the abutting relationship of the ends of the siderails 44 to the underside of the endcaps 46 is shown in Figure 4 as they are mechanically fastened to one another.
  • the cross-member 48 of the strong back panel is mechanically secured to the siderails 44 in the same manner as with the siderail interconnection of Figure 3 of the wall form panel.
  • the cross-member 48 has on its converging sidewalls 104 and 106 the arcuate channel portions 108 into which the mechanical fasteners 110 are screwed. This draws the planar face 112 of the cross-member 48 against the planar face 114 of the siderail 44.
  • the interfitting relationship of the transverse wall portion 116 to the underside 118 of the bolt slot arrangement 120 is shown.
  • the ledge portions 122 of the siderails are cut away as at 124 to receive the width of the cross member 48-at its flange extremities 126.
  • fasteners in the form of woodscrews 132 extend through apertures 134 and the flanges 128 and are screwed into the plywood.
  • fasteners 136 are used and are screwed into the transverse wall 116 of the cross-member 48, so as to be placed in shear against forces tending to pull the siderail 44 away from the cross-member 48 end portion.
  • the panel 130 has an aperture 140 provided therein to receive in this instance a circular tie.
  • the transverse wall portions 116 of the cross-member 49 has an aperture, as shown in part, at 142 to thereby allow the tie which spans opposing strong backs of the wall arrangement to extend through the strong back 24 and outwardly thereof.
  • Tie plates or walers are connected to the ties in the manner discussed in Figures 8, 9 and 11. Using this type of tie member panel with the wall form panels avoids the need to slot or kerf the siderails of the panels to receive at their interconnection, the standard flat thin bar tie member. As a result, a leakproof face is presented to the poured concrete.
  • connectors of the releasable type are used.
  • a swivel-type clamping device is used which, in a first position, may be inserted through adjacent contacting panel rails and, when swung to a second position, clamp the siderails of adjacent panels together.
  • This connector as generally designated at 34 in Figure 5, is inserted through a type of key slot 36 which has a circular central opening at 144 with outwardly extending wing slot portions 146. This arrangement is such to receive the circular end 148 of the swivel clamp 34 which has outwardly extending toggle portions 150.
  • the swivel clamp 34 has an annular base plate 152 which is secured to end 148. Between the toggles 150 and the base plate 152 is a type of lock washer 154 which operates in a manner so as to cause the distance between its face and the toggles 150 to decrease as the clamp 34 is swung downwardly in the direction of arrow 156 to draw the opposing faces of the panel rails 38 and, in this embodiment, strong back rail 44 together.
  • the handle portion 158 abuts the faces of the bolt slot arrangement 52 of the wall form panel. This relationship is shown more clearly in Figure 6.
  • the abutting contacting relationship of the siderails is generally designated at 160, as the siderails are clamped together by clamping device 34.
  • both siderails 38 and 44 are provided with ridge portions 162 and 164 which oppose and abut one another. Intermediate ridges 166 oppose one another; however, the ridges 166 are of a lesser height than ridges 162 and 164 to provide a slight spacing therebetween. This permits the faces of the siderails 38 and 44 to move slightly towards one another in providing a spring action as the swivel clamp 34 is swung downwardly in the direction of arrow 56 to provide a secure clamping of the panel siderail faces.

  • the siderail 172 has at its rear portion a flange arrangement 180 which, when it opposes the corresponding flange arrangement of the other siderail 182, forms a bolt slot arrangement.
  • the corner panels 168 and 170 may be interconnected in various manners and since an interior corner is defined, preferably bolts as at 184 are used. The bolts cause the outwardly extending face portions 174 of the panels to contact one another and define the interior corner of the wall to be poured.

  • the tie rod 18 is circular and has provided on its surface spiral-shape ridges 200 to provide a coarse thread.
  • the tie rod 18 is of sufficient length to extend outwardly beyond the bolt slot arrangements 120 of each strong back and thus extend outwardly beyond in essence the rear edge or rear face of the wall arrangement.
  • plastic tubular inserts 202 are used and which are located between the opposing panel portions 130 by insert sealers 204 which have an annular flange at 206 for abutting the faces of the panels 130.
  • insert sealers 204 may be removed from the concrete wall and the resulting holes in the wall may be patched with appropriate patching materials to provide a smooth wall finish to which finishing material may be applied.
  • a tie plate 20 is used.
  • the tie plate has an aperture 208 provided therein through which the tie rod 18 extends.
  • the aperture 208 is provided with bearing material 210 which is swedged into position to provide a bearing surface against which the connical bearing surface 212 abuts, as the winged nut 214 having wing portions 216 is threaded onto the tie 18 and tightened against the plate.
  • the tie plate has an interior surface portion at 220 which abuts the exterior surfaces 222 of the siderails.

  • the panels 22 may be removed from the strong backs 24, because the ridges 162 and 164 of the siderails simply abut one another. This is particularly useful in situations where it may be desired to remove a panel from the wall while the strong back remains against the wall, which may be supported by other angular bracing (not shown). Thus the panels may be stripped from the set wall independently of the strong backs. This approach may also be useful in situations where it is desired to provide a support arrangement for pouring concrete floors. Jack posts or shoring posts may contact the strong backs connected thereto. After the poured floor is set, the panels may be stripped from the strong backs where the strong backs with jack posts remain to support the poured set concrete floors, as it continues to cure.
  • FIG. 10 Various combinations of panels and strong backs may be used in forming a wall arrangement.
  • strong backs 24 are used at every other connection of wall form panels 22.
  • a pair of adjacent wall form panels are connected at 234 by use of the swing clamps of the type shown in Figure 5.

  • Ties 18 are provided in the strong backs to provide two levels, one at an upper level of 18a and the other at a lower level of 18b. Because all of the panels are of the same depth, the rear face of the panel arrangement 222, as discussed with respect to Figure 9, permits the use of walers or load gathering members 236.
  • walers through which the ties extend, are connected to the ties at the respective levels by way of plates 238 and wing nuts, such as 214.
  • the plates 238 are different from the tie plates 20, because they must cooperate with the external portions of the walers 236 in the manner shown.
  • the bolt slots in the panel rails provide for interconnection of intermediate panels between ties to the walers to ensure a reinforced straight modular wall form system.
  • FIG 11 A further alternative to the arrangement of Figure 10 is that shown in Figure 11, where the relationship of the walers 236 to the rear face 222 of the wall form arrangement is shown.
  • Ties 18 extend through strong backs 24 where an intermediate strong back 24, as interconnected to panels 22, does not have a tie extending therethrough. Due to the planar rear face presented by the equal depth rails of the various panels, the waler 236 contacts all of the panel rail rear edges to support the intermediate waler 24 and interconnected panels 22 to provide an arrangement with a reduced number of ties for a given span of poured wall.
  • FIG. 12 An alternative wall arrangement is shown in Figure 12 which is adapted for use with flat plate ties at panel joints.
  • the concrete forming structure comprises opposing wall arrangements 240 and 242.
  • the opposing wall arrangements are interconnected by flat plate ties 244 which fit into slot kerfed portions 246 provided in the opposing side rails. Not all of the tie members are shown; however, the arrangement is such that the ties 244 may be connected to the wall form panel siderails by key and wedge arrangements as generally shown at 248.
  • Up to six ties per panel joint may be used in a wall arrangement of Figure 12, depending upon the forces developed within the forming structure as wet concrete is poured thereinto to form a wall as represented at 250.

  • ties are required at each panel intersection. In Figure 12, only some of the ties are shown where it is understood, as previously mentioned, that ties are provided at each panel joint, the number depending upon the type of wall being poured.
  • Figure 13 shows an alternative arrangement for the siderails and cross-members.
  • the panel 252 has siderails 254 of the same cross-section as the endcaps 256. Because the siderail and endcap rail are identical in cross-section, a mitre joint may be formed for interconnecting the corners of the endcap rails to the siderails.
