ABSTRACT:
The present invention relates to a sealing plate for wall ties using a combination of sealing material and a plate which is formed to create a complete seal with the wall tie.
BACKGROUND OF THE INVENTION
As commonly known to one in the art of construction, a wall tie is used to connect an outside structure of a building made of brick or the like to an inside wall structure. The inside wall structure provides support for the outside structure. In construction of the wall, a inside wall structure is built in which the wall tie is mounted then layers of material are placed overtop of the inside wall structure. The covering layer of material must have slits which are cut to allow the wall tie to be inserted through.
These slits are very hard to precisely measure and need a considerable amount of time to seal. In the past, a worker would simply place a bead of cocking around the wall tie and spread it around with a suitable tool. Which takes up a lot of time, energy and materials and is rarely considered a suitable seal. Pressure tests are done to check for air passage through the slits and usually air does pass. When the insulation is placed on top of the cover material the seal is usually completely lost.
SUMMARY OF THE INVENTION
The present invention provides a plate which is used to create an adequate seal. A worker simply has to apply a single bead of flowable sealant material around the tie and place the plate on top. The plate is designed to evenly seal the slit and remains in place when the insulation is placed on top. The present invention takes up less time, energy and materials. Since the ties, presently sold on the market, are of considerable cost and are regularly used along with increasing requirements by engineers for a complete seal the use of the present invention is essential. The present invention supports the flowable sealant material under wind loads which cause the wall to expand.
According to one aspect of the invention there is provided a sealing plate for use with a building, the building comprising;
an inner wall structure;
an air impermeable sheet material for covering the inner wall structure and defining an air impermeable barrier;
an insulation material on top of the sheet material;
an outer wall structure outside of the insulation material;
a wall tie mounted on the inner wall structure arranged to attach to the outer wall structure for support;
the wall tie comprising a first plate portion which is vertically mounted on the inner wall structure, a second plate portion connected to the first plate portion and extending therefrom inserted vertically through a slit on the sheet material, through a second slit on the insulation material, the second portion has at least one hole in which a suitable mount means is inserted and attached to the outer wall structure connecting the inner wall structure and the outer wall structure;
the sealing plate between the material for covering the inner wall and the insulation material comprising;
a generally flat plate body defining a covering portion to create a seal around a sealing material such that the sealing material is trapped in the sealing plate.
a slot on the body for receiving the wall tie;
a raised protrusion on the body at the slot for allowing the sealing material to bead.
Preferably the wall tie has a fold portion at the first plate portion is folded at a right angle to correspond with the inner wall structure and wherein a second raised protrusion on the body is arranged for receiving the folded portion.
Preferably the sealing material is applied to the perimeter of the wall tie such that the sealing material fills the raised protrusion on the body.
Preferably the plate has an inner surface and an outer surface relative to the wall, the raised protrusion is located on the outer surface and the bead of sealant material is applied around the wall tie such that the interior of the raised protrusion at the inner surface is filled to provide a seal around the wall tie.
Preferably the raised protrusion extends upwardly at an incline from the outer surface.
According to another aspect of the present invention there is provided a building comprising;
an inner wall structure;
an air impermeable sheet material for covering the inner wall structure and defining an air impermeable barrier;
an insulation material on top of the sheet material;
an outer wall structure outside of the insulation material;
a wall tie mounted on the inner wall structure arranged to attach to the outer wall structure for support;
the wall tie comprising a first plate portion which is vertically mounted on the inner wall structure, a second plate portion connected to the first plate portion and extending therefrom inserted vertically through a slit on the sheet material, through a second slit on the insulation material, the second portion has at least one hole in which a suitable mount means is inserted and attached to the outer wall structure connecting the inner wall structure and the outer wall structure;
and a sealing plate between the material for covering the inner wall and the insulation material comprising;
a generally flat plate body defining a covering portion to create a seal around a sealing material such that the sealing material is trapped in the sealing plate.
a slot on the body for receiving the wall tie;
a raised protrusion on the body at the slot for allowing the sealing material to bead.
Preferably the wall tie has a fold portion at the first plate portion is folded at a right angle to correspond with the inner wall structure and wherein the sealing plate has a second raised protrusion on the body is arranged for receiving the folded portion.
