Abstract

An edge support rail 6 for ceramic tiles 5 has a securing flange 61 and an end flange 68 defining a recess 64 for accommodating the front edges of abutting tiles 5. The rail 6 is made of brass or aluminium and provided with apertures 62 for the passage of an adhesive and a locating shoulder 65, 66. <IMAGE>

Description

SPECIFICATION Edge Rail The present invention relates to an edge support rail for edging tile-like floor coverings, especially those made of ceramic material, which rail comprises a securing shank and an end shank which is disposed at right angles thereto and forms the support.

Supports in the wall region of floor coverings, especially when ceramic tiles or the like are involved are often formed of appropriately cut tile material or of appropriately moulded support tiles which are placed on the floor tiles and secured to the wall. The resultant join is sealed by appropriate mortar.

However, special support rails made of metal or plastics material are also known which are likewise placed on floor coverings and are secured to the adjacent wall by appropriate securing elements or adhesives.

It is an object of the invention to provide an edge support rail, especially for wet regions, i.e., for example, on terraces or balconies, which rail is to be held on the floor coverings and may cooperate with these coverings independently of the wall extensions.

According to the present invention there is provided an edge support rail for edging tile-like floor coverings, especially those made of ceramic material, which rail comprises a securing shank and an end shank which is disposed at right angles thereto and forms the support, in which an open chamber for accommodating the front edge of an abutting tile is provided, with a joint, on the end shank before the junction with the securing shank which is provided with apertures.

An edge, forming a shoulder, may be provided on the rear side of the upper end of the end shank.

In this case, the end shank may be designed as a closed or half-open hollow profile for accommodating cover profiles which are to be inserted at the front end.

A support rail of this type according to the invention may be accommodated with its thin securing shank in a layer of mortar of adhesive between the base and the tile-like floor covering to be secured. Mortar or adhesives pass through apertures in the shank so that the base, securing shank and tile are joined together. The front edges of the edging tiles are inserted into the chamber formed on the end shank. The jointing material which is made of mortar or permanent-elastic material and is inserted at the front end and at the top seals the connection over a relatively long distance in this region. The end shank lies, with a slight gap inbetween, against the abutting wall without additional securing means, so that the base, together with the support rail, may be displaced relative to the wall without tension occurring.The shoulder, formed on the upper end of the end shank by the rear edge, serves to accommodate sealing, permanent-elastic material or appropriate sealing rubber profile. In this manner, specifically when the support rail is used in the outer region of a building, the water flowing down from the wall is restrained and diverted towards the outside.

The present invention will be further illustrated by way of example, with reference to and as illustrated in the accompanying drawings, in which: Fig. 1 is a cross-section through an edge support rail; and Fig. 2 is a cross-sectional view through a support rail installed on a terrace or the like.

As illustrated in Fig. 1, the support rail, generally referenced 6, is preferably an extruded profile made of metal, for example, made of aluminium or brass. This rail has a very thin securing shank 61 which has a thickness of from 0.5mm to a maximum of 1.5mm and which may also be accommodated in the conventional thin bed layers of adhesives or the like. The apertures 62 enable the securing compound to penetrate.

The end shank 68 is at right angles to the securing shank and is preferably designed as a half-open hollow profile. The imaginary wall section 68a of an appropriate hollow profile is shown by dotted lines. The front wall is referenced 63. A chamber 64, which has a rectangular cross-section, is provided in the end shank 68 in the junction region with the securing shank 61 and is open internally. A shoulder 66 is provided on the upper end of the end shank by means of an edge 65 which protrudes beyond the rear side. The cavity of the end shank 68 is referenced 67. A terrace or balcony structure in the outer region of a building is shown, in principle, in Fig. 2. An insulating layer 3 is applied to the concrete base 1 and is generally waterresistant. The abutting wall 2 may likewise have an insulating layer towards the outside.The fiooring plaster 4 is built up over the insulating layer 3 on the floor side, and ceramic floor tiles 5 are adhered to the flooring plaster by means of a tile adhesive in accordance with the so-called thin bed layer process.

The edge support rail 6 is installed in the transitional region between the floor and the wall.

It is secured to the floor by means of its securing shank 61, the tile adhesive passing through the apertures 62 in the securing shank 61. The ceramic tiles 5 of the floor, which abut the wall, are accommodated with their appropriate front edges in the chamber 64 on the end shank 68 of the rail, secured at the front end from above, by means of mortar 7, in the appropriate joint and covered. By means of the rear side of its end shank 68, the support rail lies loosely against the wall 2, or respectively against the previously applied insulating layer 3. The upper, protruding edge 65 ensures an adequate gap from the wall.

This upper edge 65 forms the shoulder 66, in which a permanent-elastic sealing compound 8, or respectively an appropriate sealing profile, may be inserted.

In cases where the support rail terminates visibly at the front end, the hollow profile, which is half-open or sealed with the wall section 68a shown by dotted lines, may be sealed by an edging cap being inserted at the front end.

A support rail profile of this type which is particularly advantageous for installation in wet regions, for example, in the outer region of a building, may, of course, also be inserted in other regions of buildings to form supports where tensional forces between floor and abutting wall may occur.

Claims

1. Edge support rail for edging tile-like floor coverings, especially those made of ceramic material which rail comprises a securing shank and an end shank which is disposed at right angle thereto and forms the support, in which an open chamber for accommodating the front edge of an abutting tile is provided, with a joint, on the end shank before the junction with the securing shank which is provided with apertures.

2. An edge rail as claimed in claim 1, in which an edge forming a shoulder, is provided on the rear side of the upper end of the end shank.

3. An edge rail as claimed in claim 2, in which the edge protrudes beyond the end shank.

4. An edge rail as claimed in claim 1 in which the end shank is designed as a closed or half-open hollow profile.

5. An edge support rail for edging tile-like floor coverings, substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings.
