Abstract

The invention relates to a system of fixing rigid aluminum or UPVC stairnosings to a step by means of double sided adhesive tape. The double sided adhesive tape is preferably attached to a paper carrier, which is peeled off, the rigid stairnosing is then placed in position on the edge of the step. Once the rigid stairnosing is in position, pressure is applied across the step and fixing is complete. The fixing system avoids the preparational procedures that are necessary with conventional fixing methods and provides an enhanced finished product.

Description

Rigid Aluminium & Rigid uPVC Stalmoslng, Fixing System This invention

relates to the fixing of the rigid aluminium & rigid uPVC to the step floor, by use of double sided adhesive tape.

Rigid aluminium & rigid uPVC staimosings are used to edge steps, for safety, protective and decorative purposes, see figure 2.

Rigid aluminium & rigid uPVC staimosings are fixed to the edge of the step by three methods.

Mechanical fixing by use of screws to screw the rigid staimosing to the step floor.

Adhesive fixing by use of cartridge adhesive; which is applied with a skeleton gun and sticks the staimosing to the step floor.

The most common method is a combination of both mechanical fixing and adhesive fixing and is referred to as, glued and screwed.

Hover, these conventional fixing methods require a significant number of technical preparational procedures to take place, before the rigid aluminium and the rigid uPVC staimosing is ready to be fixed to the step edge.

The mechanical fixing requires a series of counter sunk holes to be drilled through the top surface of the rigid aluminium and rigid uPVC stairnosing, see figure 1.

These holes are on 25OmmI300mm centres which equates to three or four holes for each step.

These dliii holes are the holes through which the screw will pass to fix the rigid aluminium and rigid uPVC staimosing to the step floor.

This drilling procedure also creates a burr, or a jagged edge on the underside of the rigid aluminium and rigid uPVC staimosing, which disallows the rigid stairnosing to sit flat and flush on the step edge, see figure 1.

This requires for the rigid aluminium and rigid uPVC staimosing to be turned upside down, to enable the burr or jagged edge to be ground off.

The adhesive fixing, by using cartridge adhesive applied with a skeleton gun, is of a composition whereby a certain amount of curing time needs to be allowed, before the bond is strong enough to withstand the pressure of footfall upon the step.

The conventional fixing methods also require a marking procedure to take place, by way of plaang the drilled and countersunk rigid aluminium and rigid uPVC staimosing on the step edge, and then marking through the drill holes the points upon the step where the holes need to be drilled.

Once the marking has taken place, the rigid aluminium and rigid uPVC staimosing is removed, and the holes are drilled into the step edge.

When the step is a concrete step, these drill holes need to be plugged.

When the step is a steel step, mechanical fixing is not an option, and the cartridge adhesive applied by skeleton gun is used.

When the step has been drilled, fixing the rigid aluminium and rigid uPVC stairnosing takes place, and it is screwed to the step edge.

When the rigid aluminium and rigid uPVC staimosirrg has been firmly screwed to the step by gluing and screwing the drilled apertures on the visible surface of the rigid aluminium and rigid uPVC staimosing, need to be filled in by the use of plastic pips that are forced into the drilled apertures.

The invention will now be descnbed by way of written word and with reference to the accompanying drawings.

Figure 1 -Shows the drilled and countersunk holes when the conventional mechanical fixing is applied. It also shows the burr or jagged edge created on the underside. This needs to be ground off as another process.

The rigid aluminium and rigid uPVC stairnosing double sided adhesive tape fixing system is an adhesive tape on a peel off paper carrier, that is attached to the underside of the rigid aluminium and rigid uPVC staimosing, see figure 3.

Fixing is achieved by peeling off the paper carrier, and thus exposing the adhesive that will fix the rigid aluminium and rigid uPVC stairnosing to the step edge.

The open side of the double sided adhesive tape is applied to the underside of the rigid aluminium or rigid uPVC staimosing.

Figure 2 -Shows a stairnosing and where the double sided adhesive tape is applied.

The appliant side of the double sided adhesive tape is protected by a peel off paper carrier.

Figure 3-Shows the adhesive attached to the peel off paper carrier.

Once the double sided adhesive tape is applied to the underside of the staimosing, it is ready to fix into position onto the step edge.

The paper carrier is peeled off, revealing the appliant side.

The rigid aluminium or rigid uPVC staimosing is placed upon the step edge, and pushed firmly into position.

The fixing of the rigid aluminium or rigid uPVC staimosing is now complete. I, p

Claims
