Abstract
Abstract A building element for covering of roofs, walls and the like, comprising sheet members which are arranged for interconnection in any chosen number in rows after each other in two directions perpendicular to each other for forming a continuous covering. The means for interconnection of the sheet members are provided which permit movement of adjacent sheet members in the same vertical row while maintaining the interconnection of said sheet members, said means including one or more couplings provided in the upper edge of each sheet and as completent to said couplings, corresponding couplings provided and arranged in the lower edge of the sheet members on line with the upper couplings, that the upper and lower couplings of two sheet members may be connected after each other and on level with each other to define a coherent covering.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
A construction tile capable of being installed with a plurality of like tiles in vertical and horizontal substantially co-planar rows defining a coherent covering for roofs, walls and the like, each construction tile comprising, a substantially rigid plate member formed as alternating rows of raised and depressed stepped portions, said portions being stepped in the same direction taken lengthwise thereof and having stepped edges at substantially the same angle, the raised stepped portions defining an uppermost landing part and a lowermost landing part, interlocking tongue and groove means formed in the uppermost and lowermost landing parts of said raised stepped portions whereby a pair of connected adjacent tiles in the same vertical row are capable of relative displacement while retaining their interconnection as well as their interconnection with adjacent tiles of the next adjacent vertical row.
Claim 2
Dependent Claim
136 words
A construction tile capable of being installed with a plurality of like tiles in vertical and horizontal substantially co-planar rows defining a coherent covering for roofs, walls and the like, each construction tile comprising, a substantially rigid plate member formed as alternating rows of raised and depressed stepped portions, said portions being stepped in the same direction taken lengthwise thereof and having stepped edges at substantially the same angle, the raised stepped portions defining an uppermost landing part and a lowermost landing part, interlocking tongue and groove means formed in the uppermost and lowermost landing parts of said raised stepped portions whereby a pair of connected adjacent tiles in the same vertical row are capable of relative displacement while retaining their interconnection as well as their interconnection with adjacent tiles of the next adjacent vertical row.
Claim 3
Dependent Claim
101 words
The construction tile as claimed in claim 1 in which each raised stepped portion has opposite side edges and said interlocking tongue and groove means comprise an elongate first groove in one side edge of a raised stepped portion at the uppermost landing part thereof and a corresponding elongate second groove in said one side edge at the lowermost landing part of the same raised stepped portion, said first groove defining a tongue on the innersurface of said uppermost landing capable of being received within the groove at the lowermost landing of the next adjacent tile of the same vertical row.
Claim 4
Dependent Claim
41 words
A construction tile as claimed in claim 2 in which said uppermost landing converges in the direction toward the upper edge of said tile and said grooves are open ended in the direction toward the top and bottom of said tile.
Claim 5
Dependent Claim
23 words
A construction tile as claimed in claim 1 in which each tile has an upright along the edge of one depressed stepped portion.
Claim 6
Dependent Claim
39 words
A construction tile as claimed in claim 4 in which said upright has a horizontal extension of likewise stepped configuration and a sealing groove is formed in said horizontal extension extending along the entire length of said stepped portion.
Claim 7
Dependent Claim
39 words
A construction tile as claimed in claim 4 in which a corner is defined by the bottom of the outermost depressed stepped portion and said upright and sealing means seated therein and capable of being applied to said corner.
Claim 8
Dependent Claim
42 words
A construction tile as claimed in claim 1 in which the uppermost landing of each tile is formed with a water trapformation having a bottom located on a level below the next adjacent uppermost landing and includes an upright at its edge.
Claim 9
Dependent Claim
22 words
A construction tile as claimed in claim 1 in which the uppermost landing of each tile has a sealing groove formed therein.
Claim 10
Dependent Claim
41 words
A construction tile according to claim 1 in which the uppermost landing of each tile has a sealing groove formed therein and sealing material is seated in said sealing groove to engage the underside of the next adjacent tile superposed thereupon.
Claim 11
Dependent Claim
37 words
A construction tile as claimed in claim 1 in which said plate has upper and lower right hand corners defined by a depressed stepped portion, the height of which substantially corresponds to the thickness of the tile.
Claim 12
Dependent Claim
23 words
A construction tile according to claim 10 in which the uppermost landing part is wider and longer than the lowermost depressed landing part.
