Abstract
Abstract A system of structural elements are disclosed for the construction of earth filled walls. The structural elements of the system form a variety of matching elements according to various applications. The present invention includes prefabricated elements as part of a structural system and walls built by the elements, as well as the use of the structural system and structural elements for the construction of walls.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
209 words
A structural system for the construction of walls comprising a framework consisting of solid frame elements and being filled with earth material, said frame elements extending in at least one plane and having at least one support area on at least one side, said frame elements further including at least one longitudinal beam having a cross-section with at least one portion thereof arranged at an acute angle against the main plane of the frame or slab, the upper surface thereof forming a substantially flat support for said earth material, at least one such longitudinal beam being located at the front side of said wall and having an upper front edge portion being positioned at a greater height compared with said flat support and forming a board for retaining a portion of said earth material resting on said flat support, the system further including holes extending at least partly vertically through said framework and distance elements between at least two of said frame or slab elements which are positioned one above the other such that the earth material at least partially filling said vertically extending openings forms at least one sloped surface extending at least partly through the scope between said frame or slab elements positioned one above the other.
Claim 2
Dependent Claim
209 words
A structural system for the construction of walls comprising a framework consisting of solid frame elements and being filled with earth material, said frame elements extending in at least one plane and having at least one support area on at least one side, said frame elements further including at least one longitudinal beam having a cross-section with at least one portion thereof arranged at an acute angle against the main plane of the frame or slab, the upper surface thereof forming a substantially flat support for said earth material, at least one such longitudinal beam being located at the front side of said wall and having an upper front edge portion being positioned at a greater height compared with said flat support and forming a board for retaining a portion of said earth material resting on said flat support, the system further including holes extending at least partly vertically through said framework and distance elements between at least two of said frame or slab elements which are positioned one above the other such that the earth material at least partially filling said vertically extending openings forms at least one sloped surface extending at least partly through the scope between said frame or slab elements positioned one above the other.
Claim 3
Dependent Claim
32 words
The system of claim 1, wherein the said acute angle between said at least one portion of the longitudinal beam and the main plane of the frame or slab is substantially zero.
Claim 4
Dependent Claim
93 words
The system of claim 1 in which there is at least one longitudinal beam having an L-type cross-section with an upright L-portion extending upwards from said flat support portion and being positioned at the outer edge portion of the longitudinal beam, said upright L-portion being arranged at an angle relative to said main plane of the frame or slab so as to form a sloping front and/or internal surface of said board retaining the earth material, said sloping being chosen so as to form an overhang to the front side of the wall.
Claim 5
Dependent Claim
20 words
The system of claim 1 in which said at least one longitudinal beam has an at least partially arcuate cross-section.
Claim 6
Dependent Claim
31 words
The system of claim 1, having at least two frame elements stacked one upon the other, and further including a plurality of distance elements placed in between said stacked frame elements.
Claim 7
Dependent Claim
37 words
The system of claim 5, further including at least one covering slab element having a height approximately equal to the combined height of said frame and distance elements and bridging the space between said two distance elements.
Claim 8
Dependent Claim
21 words
The system of claim 6, further including at least one opening within the wall which is closed by said covering slab.
Claim 9
Dependent Claim
17 words
The system of claim 7, further including a foundation element to which said covering slab is joined.
Claim 10
Dependent Claim
22 words
The system of claim 1 further including load bearing areas that come into position only after turning the whole element by 90°.
Claim 11
Dependent Claim
18 words
The system of claim 1 having knobs 16 and matching holes 15 on at least one support area.
Claim 12
Dependent Claim
17 words
The system of claim 10 having matching holes or knobs in at least two matching support areas.
Claim 13
Dependent Claim
27 words
The system of claim 1 wherein at least one longitudinal beam of said frame or slab element has a cantilevering cross section and downward sloping outer surfaces.
Claim 14
Dependent Claim
23 words
The system of claim 1 having at least one cantilever with sloping or angular increasing cross section from the beginning of the cantilever.
Claim 15
Dependent Claim
49 words
The system of claim 1 wherein at least one element consisting of two planes is joined in an angle of less than 180°, preferably in plane slab or frame and is positioned in a way that said element stands free in an almost vertical way, joining the next element.
Claim 16
Dependent Claim
34 words
The system of claim 1 further including a knob at the transverse beam of said frame element on which said distance element of said next frame element on top touches for better shear resistance.
Claim 17
Dependent Claim
15 words
The system of claim 12 having an L-type longitudinal beam with vertical L-portion looking down.
Claim 18
Dependent Claim
25 words
The system of claim 16 wherein said downward oriented vertical L-position of the cross section is positioned at the inner side of said frame element.
Claim 19
Dependent Claim
26 words
The system of claim 12 further including a longitudinal canal in at least one longitudinal beam and including openings to the top or to the side.
