BE1000079A6 - Wall tie system - has slotted guide moved with dovetail cross-section and tie to engage at one end and forked end to engage to mortar - Google Patents

Abstract

The wall tie system, consists of a slotted guide (4) which is moulded into the cast wall, and has a recess of dovetail cross-section. The ties which engage with the guide are made e.g. from galvanised iron or stainless steel and have one end (3) which engages with the dovetail slot in the guide. The other end (2) is forked to engage with a layer of mortar. The tie can have a twist in the middle, and the forked end can be replaced by a flat end with a punched-out projection or a hole to engage with the mortar.

    "AncraRes"
The present invention relates to anchors and, in particular, to anchors which can be used with a double-cavity wall, one of which is of cast construction.



   Other details and particularities of the invention will emerge from the description below, given by way of nonlimiting example and with reference to the appended drawings, in which:
Figure I is a perspective view of an anchor according to the invention.



   Figure 2 is a perspective view of a sleeve
 EMI1.1
 to house the anchor.



   Figure 3 is an end view of the sleeve.
Figures 4 to 7 are respectively views of various anchoring arrangements.



   Figure 8 is a schematic side view showing the anchor of Figure 7 of the invention in use.



   Figure 9 is a plan view showing the anchor in use.



   Figure 10 is a perspective view of another anchor.



   If we refer to the drawings and first of all to Figures 1 to 3, we can see an anchor, shown in a way
 EMI1.2
 general by the reference numeral 1, formed from a metal strip, preferably galvanized or stainless steel. The anchor I comprises a mortar engagement end, split 2 and a notch engagement end 3 of dovetail shape. A sleeve 4 comprising a relatively narrow elongated inlet opening is also provided, this sleeve comprising a series of holes 5 for fixing to a wooden formwork support or the like.



   In use, the sleeve 4 is poured into

 EMI2.1
 The wing poured from a hollow wall. The anchor 1 is presented to the sleeve 4 as required, so that it can slide in and turn 1800 so that the notch engagement end 3 engages in the sleeve 4 behind the opening 6 .



   Referring to FIG. 4, there is illustrated another anchoring arrangement represented by the reference numeral 10, comprising a mortar engagement end, split H, and a notch engagement end 12 However, in this embodiment, an intermediate means at its ends to prevent any passage of moisture, is constituted by a twist of 150 between the ends mentioned above in 13.



   If we refer to Figure 5, we have illustrated again
 EMI2.2
 another anchoring arrangement, generally represented by the reference numeral 20, essentially similar to the anchoring
10. The anchor 20 has a slotted end 21 and a notch engagement end 22 and is twisted between its ends in
23 to prevent the passage of moisture. In addition, the anchor 20 is provided with a retaining means for housing and supporting a sheet of insulating material which is to be placed against a wing of the hollow wall.



  The retaining means of this embodiment comprises a hole 24 into which a dowel 25 is introduced.



     If Pon refers to Figure 6, there is illustrated another anchoring arrangement generally represented by the reference numeral 30, this anchoring comprising a notch engagement end 31 and a retaining means for a brick or block wing, consisting of a cutout 32.



   FIG. 7 shows yet another anchoring arrangement represented generally by the reference numeral 40, comprising a notch engagement end 41 and a hole 42 for housing a pin, a dowel assembly or the like.



   FIGS. 8 and 9 illustrate a column of poured concrete 43 in which is mounted a sleeve 44 similar to the sleeve 4 for housing the notch engagement end 31 of the anchor 40. The hole 42 of the anchor 40 comprises a dowel 45, which is introduced into the covering plate 46.

   FIG. 10 illustrates another anchoring arrangement represented generally by the reference numeral 60, this anchoring again comprising a slotted end 61 and a notch engagement end 62. However, in this form embodiment, an intermediate means is provided at its ends to prevent the passage of moisture, by twisting the anchor of each
