Abstract
A tie assembly is used in a cavity wall having a back-up wall and a brick veneer to secure the brick veneer to the back-up wall. The tie assembly includes a plate that is secured to the back-up wall in a vertical orientation, with an tying portion of the plate projecting towards the brick veneer. A series of tie openings are spaced along the outer edge of the plate to receive a tie bar that projects into the mortar between adjacent brick courses. The tie bar cooperates with the plate to transmit loads oriented in any direction in the plane of the plate between the brick veneer and the back-up wall. This means that shear loadings as well as lateral loads are transmitted between the veneer and the back up wall, so that the two act as a truss structure.
Claims20
A tie assembly for a cavity wall having a vertical back-up wall and a vertical brick veneer separated by a cavity, said assembly comprising:
- a plate having an inside anchoring portion with a plurality of fastener openings therein, and an outside tying portion;
- a tie bar with a bight and two legs projecting to one side of the bight for engagement between courses of the brick veneer;
- and
- a tie bar engaging means on the outside tying portion of the plate engaging the centre section of the tie bar and preventing substantial relative movement between the tie bar and the plate whereby:
- when the anchoring portion of the plate is secured to the back-up wall with fasteners through the fastener openings and the legs of the tie bar are engaged between courses of the brick veneer, shear forces will be transmitted between the back-up wall and the brick veneer.
A wall comprising:
- a substantially vertical back-up wall;
- a substantially vertical brick veneer spaced from and parallel to the back-up wall to define a cavity between the brick veneer and the back-up wall;
- a plate having an inside anchoring portion and a vertically oriented tying portion projecting into the cavity towards the brick veneer;
- fastening means securing the inside anchoring portion of the back-up wall and preventing relative movement of the anchoring portion and the back-up wall;
- a tie bar secured to the brick veneer between courses thereof and projecting from the veneer into the cavity;
- and
- a tie bar engaging means securing the tie bar to the tying portion of the plate, in the cavity, preventing relative movement of the tie bar and the tying portion of the plate, whereby shear forces are transmitted between the back-up wall and the brick veneer.
