DE~TAILED D~s-RIp~vN
Referring to the aceompanying drawings and pa~ticularly Figures 1 and 2, there ;s illustrated a wall 10 consisting of a back-up wall 12 covered with insulating panels 0 14 and faced with a brick veneer 16 located at some distance from the insulation to provlde a cavity 17 there between. The brick veneer 16 is a conventional brick veneer composed of bricks 18 and mortar 20. The back up wall in this embodiment is forme~ from concrete blocks 22 with mortar joints 24.
The back-up wall 12 and the brick veneer 16 are joined by a plurality of tie assemblies 26. Each tie assembly includes a flat rectangular plate 28, ~ertically oriented, with an anchoring portion embedded in mortar between two concrete blocks 22 in one course. The anchoring portion of the plate 28 has a pair of cross legs 30 extending laterally through fastening openings 32 in the plate and embedded in the mort~r between two courses of concrete blocks 22. The eross legs firmly bond the plate to the back up 20 wall.
Along tlle outer edge of the plate 28 is a series of tie openings 34. They accommodate a V-shaped tie bar 36 that has its legs embedded in the mortar Ibetween two cs)urses of bricks 18.
The plate 28 is also pro~vided with a series of retainer openings 38 that ~3~6 accommodate a wedge-shaped retainer 40 to retain the insulation panels 14 against the outer face of the back up wall 12.
~ aeferring to Figures 2 and 3, the back-up wall is typically supported on a floor slab 41. At the top, it is retained against lateral displacement by two intermediate lateral supports 42 and 43 secured to the next highest floor slab 44. A flange 45 on the lateral support 43 e~tends over the top of the insulating pan~ls, the wall cavity 17 and at least part of the brick veneer 16. At the boetom, a support 46 secured to the floor slab 41 supports the brick veneer. The tie assemblies 26 Join the veneer and the back-up ~,vall at spaced points to produce an effective truss structure as illustrated schematically in Figure o 3.
Referring to Figure 3, the truss 50 has an inner member 52, an outer member 54 and shear legs 56 joining the ewo. The inner member is supported against lateral defleceion at its upper and lower ends.
A lateral loading on the wall, such as the loading schematically represented at 62, eauses the composite wall structure to act as a truss, with the inner member 52 acting as the tension member and the outer member 54 as the compression member. In a physical wall, a loading of this sort may be caused, for example3 by winds or earthquakes.
In ~onventional cavity walls, the brick veneer is tied to the back-up wall with eies that will not sustain a shear loading, so that this effective truss structure is not 20 provided. In the absence of the truss, the back-up wall sustains all of the lateral loads and must there~e be much stronger than is the case where the brick veneer ~ntributes to hteral load resistance.
For leeward wind loads, ~at is loads acting in the opposite direction from that illust~ted at 62 in Figure 3, ~e brick veneer seTves as a tension member, while the ~3 b~ck-up wall acts as a compression member.
The detail~d configuration of the tie assembly is illustrated in Figures 4 through 8. The plate 28 is of rectangular form and has the i~our fastening openings 32 arr~nged in a rectangular array, with two openings adjacent the top edge and two openings adjacent the ~ottom edge. El~ven tie bar openings 34 are spaced along the outermost edge of the plate, while three rectangular retainer openings 38 are located generally ~entrally between the top and bottom edges of the plate and spaced along the plate between ~he outer tying portion and ~he inner anchoIing portion.
The cross legs 30 are illustrated most particularly in Figure 5. Each is a 0 round bar with a v-shaped of~set 66 at the centre and a cIimp 64 to one side of the offset.
The crimp in the tie bar is configured so that it cannot pass through the fastening opening 32. A leg lock 68 for the cross leg is illustrated in Figure 6. This is a square of stiff material with a circular opening 6g adjacent one edge and a series of radial slits 67 projecting from the radial c~pening. The leg lock may be flexed to -fit over that portion of the cross leg 30 adjacent the offset 66, on the side of plate 28 opposite the cnmp 64.
Thus, the crimp and the leg lock will cooperate to retain a cross leg in Position when it is installed through a fastening opening with the of~set 66 in the centre posi~ion.The wedge retainer 40 as illustrated most particularly in Figure 7. This is a wedge-shaped bar with a smooth inner face that engages the insulating panel and a serrated 20 outer face 70 that serves to grip the con~ronting edge of the retainer opening 38 to prevent unwanted displacement of the retainer 40 out of the opelling 38.
The tie bar 36 is generally V-shaped, with a bight 72, divergent legs 74 and oppositely projecting leg end sections 76. In ~e installed condition of the tie bar, ~e bight 72 is centered in one of the tie openings 34 and the legs and leg ends ~e seated in the ~,3C~
mortar between two courses of brick.
Figure 9 illustrates the installation oî the tie assembly in a cavity wall with an insula~ion layer and a concrete block back-up wall. The cross legs 30 pas5. through the bottom fastening openings 32 and are seated in a layer of mortar 24 between two concrete blocks 22. The triangular tie bar 36 extends from ~e uppermost tie opening 34 directly into the mortar 20 bet veen ewo courses of bricks 18. In installing the stIucture, the tie bar is inserted in whichever of the tie openings 34 that will provide this relationship.
In this embodiment~ the retainer openings 78 are circul~r and a circular pin 80 serves as the insulation retainer, retaining the layer of insulation 14 against the concrete 0 block back-up wall. Where desired, the cores of the concrete block can be reinforced and/or grouted to improve the performance of the entire system.
Figure 10 illustrates the use of a tie assembly similar to that in Figure 9 for securing a brick veneer to a stud wall. In this case, the plate 28 is secured to a wooden stud 82 by four nails 84 through the fastening openings 32.
Where metal studs ar~ used, the nails will be replaced by appropriate screws ~r other fasteners.
While particula~ embodiments of the present invention have been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the present invention. For example, the shape and dimensions of the plate 28 may 20 vary widely according to ~e strength, wall dimensions and other physical characteristics of the particular application. The ~e bars 36 may also vary in form~ provided only that the key to ~e mortar 20 between the bncks is adequate to transmit to ~e plate loadings in all orientations within the plane of the plate. Thus, the invention is to be considered limited solely by the scope of the appended claims.
