Abstract
Abstract The invention provides building elements for making floor or wall panels. Each element has a plurality of upper plates and a plurality of lower plates, the plates being aligned, parallel and staggered, with interconnecting webs between the upper and the lower plates, respectively. Several elements are interwoven and bonded to make a panel having a face comprising the upper plates and a back comprising the lower plates. Posts projecting from the back faces of the upper plates improve the strength of the panel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
A plastic building element comprising a plurality of identical first substantially square plates arranged in spaced relationship in a first coplanar rectilinear row, the spacing between successive first plates being equal to the longitudinal dimension of said first plates; a plurality of identical second rectangular plates arranged in spaced relationship in a second coplanar rectilinear row spaced from, parallel to, and aligned with said first row, the longitudinal dimension of said second plates and the spacing between successive second plates being equal to the longitudinal dimension of said first plates, and the transverse dimension of said second plates being less than the transverse dimension of said first plates; and a plurality of webs respectively connecting the adjacent edges of a first plate and a second plate, each web being perpendicular to said first row and said second row, and each web lying entirely within the edge of its associated first plate and externally of the edge of its associated second plate.
Claim 2
Dependent Claim
161 words
A plastic building element comprising a plurality of identical first substantially square plates arranged in spaced relationship in a first coplanar rectilinear row, the spacing between successive first plates being equal to the longitudinal dimension of said first plates; a plurality of identical second rectangular plates arranged in spaced relationship in a second coplanar rectilinear row spaced from, parallel to, and aligned with said first row, the longitudinal dimension of said second plates and the spacing between successive second plates being equal to the longitudinal dimension of said first plates, and the transverse dimension of said second plates being less than the transverse dimension of said first plates; and a plurality of webs respectively connecting the adjacent edges of a first plate and a second plate, each web being perpendicular to said first row and said second row, and each web lying entirely within the edge of its associated first plate and externally of the edge of its associated second plate.
Claim 3
Dependent Claim
81 words
A plastic building element according to claim 1, in which the number of first plates is equal to the number of second plates, and which includes a first end wall extending perpendicularly from the terminal edge of the terminal first plate and a second end wall extending perpendicularly from the terminal edge of the terminal second plate, said end walls being parallel to and aligned with the webs, and such end wall lying within the terminal edge of its associated plate.
Claim 4
Dependent Claim
36 words
A plastic building element according to claim 1, which includes a plurality of posts extending perpendicularly from the inner surface of each first plate for a distance corresponding to the spacing between the rows of plates.
Claim 5
Dependent Claim
53 words
A plastic building element according to claim 1, in which the outer surface of each first plate is provided with a groove running parallel to and near each edge of such first plate, each groove extending the full length of its associated edge, for the purpose of receiving and guiding a plastic-bonding tool.
Claim 6
Dependent Claim
110 words
A panel comprising a plurality of interwoven longitudinally positioned and transversely positioned plastic building elements according to claim 1; said respective building elements being so arranged that each first plate of a longitudinally positioned element overlies a second plate of a transversely positioned element and each first plate of a transversely positioned element overlies a second plate of a longitudinally positioned element, with the webs extending from each such first plate engaging the longitudinal edges of the associated overlain second plate; the first plate of each element being plastic-bonded to its respective adjacent first plates; and the second plate of each element being plastic-bonded to its respective adjacent second plates.
Claim 7
Dependent Claim
34 words
A panel according to claim 5, which includes plastic inserts respectively plugging the openings occurring at the corners of adjacent second plates, each such plastic insert being bonded to its respective adjacent second plates.
