Abstract
Abstract A grid plate for stabilizing natural ground comprises a base and side walls formed in one piece with the base which form chambers open to the top being in the form of regular polygons, the base having water outlets, the chambers being in the form of sectional chambers which are laterally open on their periphery which form closed chambers with laterally open sectional chambers of adjacent grid plates complementary thereto when two similar grid plates are assembled and the ends of side walls of both grid plates forming the sectional chambers come into contact, the side walls having flattenings in the regions of contact, the flattenings of complementary chambers lying flat on one another when two similar grid plates are joined together.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
A grid plate for stabilizing natural ground, comprising a base and side walls formed in one piece with the base which form chambers open to the top being in the form of regular polygons, the base having water outlets, the chambers being in the form of sectional chambers which are laterally open on their periphery which form closed chambers with laterally open sectional chambers of adjacent grid plates complementary thereto when two similar grid plates are assembled and the ends of the side walls of both grid plates forming the sectional chambers come into contact, the ends of the contacting side walls having flattenings in the region of contact formed as bends at the ends of the side walls, the bends at the ends of two complementary side walls lying flat against each other when two similar grid plates are joined together.
Claim 2
Dependent Claim
142 words
A grid plate for stabilizing natural ground, comprising a base and side walls formed in one piece with the base which form chambers open to the top being in the form of regular polygons, the base having water outlets, the chambers being in the form of sectional chambers which are laterally open on their periphery which form closed chambers with laterally open sectional chambers of adjacent grid plates complementary thereto when two similar grid plates are assembled and the ends of the side walls of both grid plates forming the sectional chambers come into contact, the ends of the contacting side walls having flattenings in the region of contact formed as bends at the ends of the side walls, the bends at the ends of two complementary side walls lying flat against each other when two similar grid plates are joined together.
Claim 3
Dependent Claim
31 words
A grid plate as defined in claim 1, further including projections from at least one edge thereof, for engaging with the edge of a base of an adjacent similar grid plate.
Claim 4
Dependent Claim
31 words
A grid plate as defined in claim 2, wherein each flattening is formed as a right angle bend at the end of a side wall, into the shape of an L.
Claim 5
Dependent Claim
28 words
A grid plate as defined in claim 3, wherein the bends of two complementary side walls of adjacent grid plates have the bend formed in a different direction.
Claim 6
Dependent Claim
64 words
A grid plate as defined in claim 3, wherein the bends of two complementary side walls of adjacent grid plates have the same direction of bend, and the complementary side walls are each at an angle deviating from a corner angle of the regular polygon with an adjacent side wall of the same seotional chamber, whereby the flattenings can lie flat against one another.
Claim 7
Dependent Claim
42 words
A grid plate as defined in claim 1, wherein each flattening of the side wall ends of adjacent grid plates is formed with a face wall standing at right angles to the end of the adjoining side wall and forming a T-shape.
Claim 8
Dependent Claim
54 words
A grid plate as defined in claim 1, wherein each flattening of adjacent grid plate side wall ends is formed as an acute angled bend of each adjoining side wall which has an obtuse angled opposing bend in its run from a mating corner of a polygon shaped chamber to the acute angled bend.
