Abstract
Abstract There is provided a novel adhesive-backed tile panel protected by a release sheet. The prefabricated tile panel comprises a substrate sheet composed of a core fabric and a heat-softening-adherent asphalt composition applied to the both surfaces of the fabric; an adhesive layer having convex and concave portions such as stripes of an adhesive not flowable but sticky at an ambient temperature; and tiles arranged regularly and secured to the asphalt composition layer of the substrate sheet. The convex portions and concave portions of the adhesive layer constitute the gaps through which air present between the tile panels and a substrate board can be purged upon installation of the tile panels. The tile panels can be installed readily on a substrate board having thereon horizontal indication means such as crosspieces by removing the release sheet, mounting the tile panels on the substrate board, and pressing the mounted tile panels to purge air present between the panels and the board through the gaps of the adhesive layer and to increase the effective adhesion areas of the adhesive layer. A unit substrate board having specified structures for assembling a preferred substrate board is also provided for installation of the tile panels.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
238 words
A prefabricated title panel having side dimensions of about 300 mm or more which consists essentially of a substrate sheet composed of a core nonwoven fabric and a heat-softening-adherent polymer-modified asphalt material applied to both surfaces of the fabric, the thickness of the substrate sheet being about 0.5 to about 3 mm; an adhesive layer having convex and concave stripe portions with gaps therebetween comprising a heat-melting adhesive which is not flowable but sticky at an ambient temperature in the form of stripes adhered to one surface of the adherent material of the substrate sheet, said convex and concave stripe portions having such a thickness and being arranged at such an interval that the panel can be bonded firmly to a substrate board and air present between the back surface of the panel and a substrate board upon installation thereof can be purged through the gaps between the convex portions and the concave portions of the adhesive layer, an area coverage ratio of the convex stripes being about 30% to about 70%, the width and interval of the stripes being in the range of about 2 to about 8 mm, the convex stripes having a thickness of about 0.5 to about 3 mm; said adhesive layer being protected by a release sheet; and a multiplicity of ceramic or porcelain tiles arranged regularly and secured by heating to the other surface of the adherent material of the substrate sheet.
Claim 2
Dependent Claim
238 words
A prefabricated title panel having side dimensions of about 300 mm or more which consists essentially of a substrate sheet composed of a core nonwoven fabric and a heat-softening-adherent polymer-modified asphalt material applied to both surfaces of the fabric, the thickness of the substrate sheet being about 0.5 to about 3 mm; an adhesive layer having convex and concave stripe portions with gaps therebetween comprising a heat-melting adhesive which is not flowable but sticky at an ambient temperature in the form of stripes adhered to one surface of the adherent material of the substrate sheet, said convex and concave stripe portions having such a thickness and being arranged at such an interval that the panel can be bonded firmly to a substrate board and air present between the back surface of the panel and a substrate board upon installation thereof can be purged through the gaps between the convex portions and the concave portions of the adhesive layer, an area coverage ratio of the convex stripes being about 30% to about 70%, the width and interval of the stripes being in the range of about 2 to about 8 mm, the convex stripes having a thickness of about 0.5 to about 3 mm; said adhesive layer being protected by a release sheet; and a multiplicity of ceramic or porcelain tiles arranged regularly and secured by heating to the other surface of the adherent material of the substrate sheet.
Claim 3
Dependent Claim
18 words
The tile panel according to claim 1, in which the release sheet has one or two perforation lines.
Claim 4
Dependent Claim
18 words
The tile panel according to claim 1, in which the heat-softening adherent material is a resin-modified asphalt composition.
Claim 5
Dependent Claim
17 words
The tile panel according to claim 3, in which the adherent material is a rubber-modified asphalt composition.
Claim 6
Dependent Claim
132 words
The tile panel according to claim 1, which has been installed on a substrate board by the steps comprising setting the tile panel from which the release sheet was removed over the substrate board; mounting the adhesive layer of the tile panel on the substrate board; pressing the top surface of the tile panel to purge air present between the adhesive layer of the tile panel and the surface of the substrate board through the gaps formed among the convex portions and concave portions of the adhesive layer, the gaps being communicated with the outsides of the tile panel, as well as to increase effective adhesive areas of the convex portions of the adhesive layer by the pressing force applied thereto; and filling a joint compound into the joints of the tiles.
Claim 7
Dependent Claim
38 words
The tile panel according to claim 5, in which the substrate board has thereon means for indicating horizontal positions of the tile panels, the means being arranged at an interval of the vertical width of the tile panel.
Claim 8
Dependent Claim
18 words
The tile panel according to claim 6, in which the means for indicating horizontal positions are horizontal crosspieces.
Claim 9
Dependent Claim
19 words
The tile panel according to claim 20, in which the means for indicating horizontal positions are horizontal dotted protrusions.
Claim 10
Dependent Claim
45 words
The tile panel according to claim 6, in which some portion of the release sheet has been removed first, the tile panel has been mounted on the substrate board and its portion adjusted, and then the remaining portion of the release sheet has been removed.
Claim 11
Dependent Claim
78 words
The tile panel according to claim 6, in which the substrate board is composed of a plurality of unit substrate boards, and each unit substrate board has two crosspieces arranged horizontally in the ratio of the interval between the top end of the unit substrate and the upper crosspiece to the interval between the two crosspieces to the interval between the lower crosspiece and the bottom end of the unit substrate board being in a ratio of 1:3:2.
Claim 12
Dependent Claim
38 words
The tile product according to claim 6, in which at least the top and bottom edges of the unit substrate board have been made thinner than the remainder of said unit substrate board to facilitate applying water-proof tapes.
