Definitions

  • the present invention relates to a wall tie device comprising a wall bracket and connecting tie for the purpose of tying a brick or block structure to an existing structure.
  • GB-A-1575501 discloses a bracket in accordance with the precharacterising part of claim 1; in this prior device, flanges extending forwardly of the backplate define a T-shaped channel into which the correspondingly shaped feet of a tie are inserted.
  • this prior device requires that either the ties are inserted in the channel with their feet extending lengthwise of it and then are twisted through a right angle to engage with the flanges or that the ties are slid in from the ends.
  • the present invention relates to an improved form of wall bracket.
  • a bracket for use with a wall tie having a pair of limbs, for tying a brick or block structure to an existing structure
  • the bracket comprising a backplate with a series of means at intervals along its length for securing the bracket to the existing structure and the backplate having at least one socket in which the tie is engageable to link the tie with the bracket, the socket being adapted so as to permit the tie, while so engaged, to be adjustable in its position lengthwise of the backplate and to be interposed between courses of new bricks or blocks, characterised in that the or each socket is constituted by at least one aperture in the backplate; the socket is so shaped in the plane of the backplate as a) at one position lengthwise of the plate to permit the free ends of the limbs of the tie to be insertable in the socket by pushing the tie perpendicularly or approximately perpendicularly towards the backplate of the bracket and thus into the socket and b) to permit the tie with the free ends of its limbs so engaged to slide lengthwise
  • the invention can thus avoid the problem of having to manufacture a range of brick size-dependent brackets by permitting the tie to slide lengthwise of the bracket to accommodate different brick sizes. Further, since the tie can be engaged with the bracket by pushing it perpendicularly towards the backplate of the bracket, there is no need for either end of the bracket to be accessible (as in certain prior tie devices) in order to be able to insert the tie.
  • the range of adjustability is at least 1 cm, more preferably at least 2 cm.
  • Each socket may comprise a widened part for receiving the free end of the tie limb and a portion extending longitudinally of the backplate for allowing the tie to slide longitudinally of the backplate.
  • each socket may comprise a pair of apertures symmetrically disposed about the longitudinal centre line of the backplate.
  • each socket may comprise an aperture having portions adapted to enable both free ends of the tie to be inserted therein.
  • each socket is generally symmetrical about the longitudinal axis of the backplate.
  • the means for securing the bracket to the wall may comprise a row of securing means along the backplate of the bracket and the sockets are preferably arranged to permit vertical adjustability of the ties in the space between respective adjacent securing means.
  • the securing means may be a series of fixing holes disposed along a line extending lengthwise of the bracket.
  • the apertures of each pair of apertures are disposed to opposite sides of this row of fixing holes.
  • the or each aperture may have side edges shaped to provide one or more longitudinally spaced detent positions at which the tie will be restrained from further sliding movement.
  • brackets By making the various features of the brackets symmetrically about the longitudinal centre of the bracket, the bracket does not require to be installed one particular way up.
  • the bracket of which one end portion is shown in Figures 1A, 1B is stamped and folded out of sheet metal and comprises a back plate 1 having a surface 2 which faces the new brickwork and a reverse surface 3 which faces the existing structure.
  • the bracket may be suitably coated, or be of a suitable material, to be highly resistant to corrosion.
  • the bracket is provided with two side flanges 4 to overlie a brick or block of the new structure and formed by folding the material of the bracket at right angles to the back plate 1, these flanges being provided with a row of keying holes 5 for mortar, plaster or rendering.
  • a series of fixing holes 6 Disposed along the longitudinal centre line of the back plate is a series of fixing holes 6 of rounded oblong or oval shape (to provide a degree of lateral adjustability of the bracket when fixed to the wall) and disposed to each side of this row of holes are a row of sockets each formed of a pair of apertures 7 which are arranged to opposite sides of the centre line of the back plate.
  • Each aperture 7 is in the form of a "[" and comprises an elongate centre portion 8 and, at each end of this centre portion, a recess 9 which allows the entry of feet 22 of a tie 20 (to be described below). As shown the recesses 9 extend outwardly from the centre portion 8 but they need not in other constructions.
  • the bracket is provided with a number of "feet" 10 which are provided to maintain the back plate 1 in parallel spaced relation to the existing wall so as to provide space for the "feet” 22 of the tie and so that the rear surface 3 is stood off from the surface of the existing wall.
  • This provides a space into which mortar from between the new courses of bricks can enter via a number of keying holes 11 in the back plate 1 and thus help bond the new wall to the existing one (provided there is no excessive relative vertical movement of the two walls).
  • the holes 11 are located vertically between the two recesses 9, of a cut out 7 since it is at this level that the mortar between courses of the new wall will be located.
  • brackets 1A and 1B Only the end portion of the bracket is shown in Figures 1A and 1B. As can be seen in Figure 1B, the side flanges 4 stop short of the end of the bracket and have a rounded corner.
  • the other end of the bracket can be of corresponding layout, with the centre part comprising as many repeats as are necessary to achieve the desired length, of the lower section in Figure 1A.
  • the tie 20 is shown to be generally "U” shaped and is made of metal wire or rod material and has two side by side resilient limbs 21 which initially converge, moving away from the web of the "U” and then, about halfway along diverge. At their free ends they have outwardly directed "feet” 22. (They might equally well be inturned with the recesses 9 being similarly inturned to correspond).
  • brackets such as one in Figure 1 are fixed to the old wall along the vertical line from which the new wall will extend. There may be a continuous or intermittent arrangement of these brackets along this line. Alternatively one continuous bracket may be used.
  • the bracket may be fixed to the existing structure by any suitable means such as nails, screws or bolts so as to fix the bracket 1 firmly to the wall. Every so often a tie must be fixed to the bracket and be placed on top of the top course of bricks so far laid so that in the laying of the next course of bricks the tie is firmly interposed between them and strongly holds these new bricks to the bracket. This is done by squeezing the legs 21 of the tie together and inserting them in the upper recesses 9 by pushing the tie perpendicularly, or at least approximately perpendicularly to the back plate 1.
  • the legs of the tie can be released so that they spring outwards so as to engage with the laterally outer edges of the apertures and the tie can then be slid downwardly until it rests on the uppermost course of bricks.
  • This lengthwise sliding of the tie makes it possible to place it at whichever position is necessary to interpose it between two courses of new bricks.
  • each socket into which the feet 22 of a tie 20 is slotted can be formed of a single aperture in the shape of an "I" with the upright of the "I” located along the centreline for the back plate; the upper and lower transverse limbs allow sufficient space for outwardly directed tie feet to be inserted. Further squeezing of the tie limbs close together will allow the tie to slide along the length of the longitudinal limb to the required position.
