Definitions

• THIS INVENTION relates to a method of construct ⁇ ion and in particular to a method of attachment of frameworks or panels to a base support.
• the method of the invention includes the followin steps:
• the intermediate support member is attached to the base support prior to or after step (ii) .
• step (ii) may be repeated wherein one or more panels or frameworks may be attached to "the intermediate support member adjacent the first mentioned panel or framework.
• the base support member is a concrete slab.
• any other appropriate base support member could be utilized such as a metal or wooden block or sheet.
• the intermediate support member is elongate and may comprise either a plate like member or rail member.
• the intermediate support member is formed from wood although it may be formed from plastics, metal, concrete or any other suitable material.
• the intermediate member may be considered to be a "tracking" rail and thus support a plurality of wall frameworks.
• the inter ⁇ mediate member may be bolted or attached to the concrete slab in any suitable manner.
• the intermediate member is attached to the concrete slab by expanding bolts inserted through aligned apertures in the intermediate member.
• the expanding bolts may be applied by an appropriate triggering mechanism or gum.
• intermediate member may be supported by chocks, spacers or suitable packing as is known in the art if the concrete slab is uneven so that
• a top surface of the intermediate member may be relatively even or substantially planar.
• the intermediate member in a preferred embodi ⁇ ment of the invention may be provided with a plurality of attachment cavities which are located suitably in the top surface of the intermediate member.
• the cavities may be formed in any suitable manner such as by routing or punching.
• the cavities are rectangular although this is not essential.
• each cavity may be surrounded by a shallower recess or groove so as to allow installation of a fixing plate (usually although not essent ⁇ ially formed from metal) for a reason as hereinafter described
• the intermediate rail may include a plurality of upwardly projecting locating members or bolts which may locate in corresponding apertures or recesses in the bottom frame member of the building framework when the framework is suitabl brought into engagement with the intermediate member in ;Step (ii) .
• the building framework may be lowered manually but more effectively by crane so that the bottom frame member thereof bears against the intermediate rail and is located therein by the above described locating means.
• the building or wall framework suitably comprises a bottom frame member or "bottom plate", top frame member or “top plate” and interconnecting studs as is known in the art.
• a rigid panel may also be utilized as well as or in preference to a wall framework in accordance with the method of the invention
• the "bottom frame member” would mean a bottom wall or appropriate lower portion of the rigid panel.
• the bottom frame member of the wall framework is provided with a plurality of downwardly extending attachment bolts which engage in the above described attachment cavities of the intermediate member.
• the bottom frame member of the wall framework is provided with a plurality of downwardly extending attachment bolts which engage in the above described attachment cavities of the intermediate member.
• each attachment bolt is threaded and he nut suitably of hexagonal shape loosely attached thereto.
• the abovementioned fixing plate may include a central aperture of complementary shape to the nut although this is not necessary and usually the central aperture is circular and longer than the widest dimension of the nut.
• the fixing plate may also have one or more apertures located adjacent the central aperture which register with aligned apertures passing through the intermediate member for inserting therethrough of the abovementioned expansion bolts which attach the intermediate member to the concrete slab.
• locking means for maintaining the attachment bolts of the bottom frame member of the wall framework in a locked position in their respective attachment cavities.
• the locking means is usually chosen so as to prevent disengagement between the attachment bolts and the attachment cavities due to uplift or racking (e.g. lateral) forces.
• one or more locking shims or bifurcated members or other suitable locking members which are attached to the lower end of the attachment bolt before fastening of the nut.
• the locking shims are U shaped members which are attached to the attachment bolt in different orientations - i.e. one locking shim is located about the bolt so that the arms of the U are substantially parallel to the plane of the bottom frame member of the framework (i.e. substantially horizontal) .
• the other locking shim may then be attached to the attachment bolt so that the arms of U are normal to the arms of the first mentioned locking shim.

• wall framework
• Bottom frame member 13 has attachment members or bolts 20 projecting downwardly therefrom with bolts 20 having nuts 21 mounted thereon. 15 Intermediate member 11 is attached to concrete slab 10 by expanding bolts 18. When frame member 13 is lowered by a crane (not shown) the bottom surface of frame member 13 bears against the top surface of member 11. Locating bolts 16 engage in locating recesses 15 in frame member 13 20 and bolts 20 locate in attachment cavities 19 of member 11.
• Member 11 may be attached to slab 10 by expans ⁇ ion bolts 18 passing through apertures 25 in fixing plate 17, passages 30 in rail 11 and aligned recesses 27 in slab 10. Plate 17 is located in opposed grooves 28 of surrounding cavity 25 19. There is also shown U shaped locking members 22 and 23 interposed between nut 21 of bolt 20 and fixing plate 17.
• **5* to a vertical orientation, so that they align and butt evenly with adjoining panels. After this is achieved bracing and sheeting is possible.
• Step 1 Before sheeting and bracing prefabricate wall panel 12 holes were drilled in bottom plate 13 and bolts 20 were inserted at spaced intervals in bottom plate 13. The panel 12 was aligned with its tracking member 11 and holes were drilled in both at the same time to take location bolts 16 which were inserted at a later stage. ' Step" 2. The intermediate support member or tracking plate 11 was placed on an uneven support slab 10
• Step 4 Fixing plates 17 were located on opposed grooves 28 of cavities 19.
• Locating bolts 16 were positioned in support member 11.
• the tracking plate II was fastened to support surface 10 through pre-drilled holes 25 of fixing plate 17 and using expansion bolt 18.
