Abstract
Abstract A structural element system comprising substantially L-shaped longitudinal elements arranged in multi-level relationship having a horizontally extending base plate portion and an upwardly extending parapet element, and sectional support elements acting as vertical spacers for the longitudinal elements extending perpendicular to the direction of the longitudinal elements, the sectional supports having upper and lower mounting surfaces and adopted for engagement by the base plate portions of the longitudinal elements to provide a wall capable of dividing shearing forces acting on the wall vertically and longitudinally so that the wall stands erect, retaining a slope surface and provides areas for the accommodation of plants, small foliage or the like.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
214 words
A structural element system for the erection of plant accommodating, slope retaining walls comprising (a) a plurality of substantially L-shaped longitudinal elements arranged in multi-level relationship having a horizontally extending base plate and an upwardly extending parapet forming the front of the wall and providing plant growth medium support surfaces, and (b) a plurality of section support elements acting as vertical partitions along said longitudinal elements, extending horizontally in a direction perpendicular to the direction of said longitudinal elements and extending into the slope to be retained, (c) said section support elements having upper and lower mounting surfaces adapted to be stacked one upon the other, (d) each of said section support elements being provided with a recess which is open to the front, into which the base plate of the longitudinal elements extends, the longitudinal elements being supported by said support elements, whereby the shearing forces of the earth slope along the wall are sectioned by the vertical partitions and by the base plates of said longitudinal elements, (e) each of said section support elements being further provided with a front flange extending from said section support element forwardly of said parapet and adjacent the recess for transmitting the horizontal slope stresses exerted on said longitudinal elements back to said section support elements.
Claim 2
Dependent Claim
214 words
A structural element system for the erection of plant accommodating, slope retaining walls comprising (a) a plurality of substantially L-shaped longitudinal elements arranged in multi-level relationship having a horizontally extending base plate and an upwardly extending parapet forming the front of the wall and providing plant growth medium support surfaces, and (b) a plurality of section support elements acting as vertical partitions along said longitudinal elements, extending horizontally in a direction perpendicular to the direction of said longitudinal elements and extending into the slope to be retained, (c) said section support elements having upper and lower mounting surfaces adapted to be stacked one upon the other, (d) each of said section support elements being provided with a recess which is open to the front, into which the base plate of the longitudinal elements extends, the longitudinal elements being supported by said support elements, whereby the shearing forces of the earth slope along the wall are sectioned by the vertical partitions and by the base plates of said longitudinal elements, (e) each of said section support elements being further provided with a front flange extending from said section support element forwardly of said parapet and adjacent the recess for transmitting the horizontal slope stresses exerted on said longitudinal elements back to said section support elements.
Claim 3
Dependent Claim
26 words
A structural element system as set out in claim 1, wherein (a) the recess in each of said support elements is in the lower mounting surface.
Claim 4
Dependent Claim
25 words
A structural element system as set out in claim 1, wherein (a) the recess in each of said support elements is intermediate the height thereof.
Claim 5
Dependent Claim
46 words
A structural element system as set out in claims 1 or 2, wherein (a) each of said front flanges projects forwardly above the lower mounting surface of said support elements, on the forward edge of which flange is mounted the base plate of said longitudinal element.
Claim 6
Dependent Claim
40 words
A structural element system as set out in claim 1, wherein (a) said base plate is shorter than said parapet of the longitudinal element, the base plate and parapet forming an angle in the range of approximately 70° to 110°.
Claim 7
Dependent Claim
36 words
A structural element system as set out in claims 1 or 2, wherein (a) the front surface of said support elements are inclined at an angle corresponding to the angle at which said parapet is inclined.
Claim 8
Dependent Claim
63 words
A structural element system as set out in claims 1 or 2, wherein (a) the base plates of said longitudinal elements lie within the recesses of the section support elements in spaced relation to that part of the support elements defining the upper limit of the recess, and the said parapet is adjacent, but spaced from, the front surface of said support element.
Claim 9
Dependent Claim
42 words
A structural element system as set out in claim 7, wherein (a) the bottom recess of said support element is higher than said base plate and is shorter in length than base plate between its rearside and the back of said parapet.
Claim 10
Dependent Claim
27 words
A structural element system as set out in claims 1 or 2, wherein (a) the height of said support elements is less than that of said parapet.
Claim 11
Dependent Claim
77 words
A structural element system as set out in claims 8, wherein (a) the front bottom recess of each of said support elements is of such dimensions that the wall of the support element defining the rear limit of the recess is above the upstanding flange of the support element lying thereunder, and the portion of the support element over the recess is above said parapet of the longitudinal element lying thereunder, whereby a vertical wall is created.
Claim 12
Dependent Claim
52 words
A structural element system as set out in claim 3, wherein (a) the recess in each of said support elements is midway of the height thereof, providing a mounting surface for the base plate of said longitudinal element, and (b) a front flange extending upwardly from said mounting surface adjacent the recess.
Claim 13
Dependent Claim
28 words
A structural element system as set out in claims 1 or 3, wherein (a) said support elements are provided with transverse openings for economy of weight and material.
Claim 14
Dependent Claim
83 words
A structural element system as set out in claim 1 with the addition of (a) a foundation, (b) said support elements being stacked on said foundation one above the other, thereby forming transverse walls extending into the earth of the slope to be shored, so that the slope stress forces in the space between adjacent stacks of support elements are absorbed in increments over the length of said longitudinal elements and transmitted through the support elements to said foundation and into the earth.
Claim 15
Dependent Claim
67 words
A structural element system as set out in claim 1, wherein (a) the longitudinal elements extending between adjacent support element stacks are in staggered contact with its stack of support elements with respect to the other longitudinal elements which extend in the longitudinal direction of the wall between said support element stacks, and said longitudinal elements overlap in the area of each of said support element stacks.
Claim 16
Dependent Claim
35 words
A structural element system as set out in claim 1, wherein (a) the distance between the adjacent support element stacks is essentially less than the length of said longitudinal elements resting on said support elements.
