Definitions

  • This invention relates to a method of building a cavity wall and to ties which may be used in the method of the invention.
  • a method of building a cavity wall includes the step of embedding in the leaves of the cavity wall a tie to locate them in position the method being characterised in that a tie is used in which at least the portions which are located in the walls and adjacent to the leaves of the wall are of spiral form and obtained by twisting a flat strip of material, preferably of metal.
  • the tie which is used is of spiral form throughout its length.
  • the invention also relates to a building tie for use in the method as set forth which is formed by twisting a flat strip of metal at least at its ends into a spiral and preferably over the whole of its length.
  • the tie is preferably of a width of approximately 7 millimetres, with a thickness of I millimetre.
  • the pitch of the turns of the spiral are between 15 and 20 mm and although the tie may be of any suitable length it is conveniently of 200 - 205 mm.
  • the invention also includes within its scope a cavity wall made by the method as set forth
  • the wall tie shown is formed from a flat strip of metal by twisting it so as to obtain the spiral form shown.
  • the most suitable material for the strip has been found to be 304 stainless steel or 316 stainless steel.
  • the width of the stainless steel strip used is 7 mm, its thickness lmm, and has pitch of 15 - 20 mm between adjacent turns of the spiral.
  • the length is of 200 - 205 mm, although it can be of any convenient length.
  • the building ties are embedded in the wall as shown in Figure 3.
  • Each end of the tie indicated generally at 1 is embedded into a layer of mortar 2 between bricks or other building blocks 3 forming the leaves of the wall.
