Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
130 words
A protective wall structure having a high resistance to blast and fragments, characterized in that it includes; two spaced groups of panels of rigid metal sheets, the sheets of each group having ends in interlocking relationship with the ends of the adjacent sheets of the respective group and defining therewith each of the two opposite faces of the wall structure, the interlocking ends of one group of face panels being non-aligned with the interlocking ends of the other groups of face panels; a plurality of diagonal panels of rigid metal sheets extending diagonally between the face panels and having ends in interlocking relationship with each of the interlocking ends of the face panels; and a filling material filling the space between the face panels and embedding the diagonal panels therein.
Claim 2
Dependent Claim
130 words
A protective wall structure having a high resistance to blast and fragments, characterized in that it includes; two spaced groups of panels of rigid metal sheets, the sheets of each group having ends in interlocking relationship with the ends of the adjacent sheets of the respective group and defining therewith each of the two opposite faces of the wall structure, the interlocking ends of one group of face panels being non-aligned with the interlocking ends of the other groups of face panels; a plurality of diagonal panels of rigid metal sheets extending diagonally between the face panels and having ends in interlocking relationship with each of the interlocking ends of the face panels; and a filling material filling the space between the face panels and embedding the diagonal panels therein.
Claim 3
Dependent Claim
15 words
The wall structure according to claim 1, wherein said filling material is concrete or asphalt.
Claim 4
Dependent Claim
38 words
The wall structure according to claim 2, wherein said face panels are formed with stepped, inwardly-bent ends, which ends of adjacent panels are in nesting interlocking relationship with each other and with the ends of the diagonal panels.
Claim 5
Dependent Claim
38 words
The wall structure according to claim 3, wherein said diagonal panels are also formed with stepped ends and are disposed in a saw-tooth configuration coming together in nesting relationship with the stepped bent ends of the face panels.
Claim 6
Dependent Claim
66 words
The wall structure according to claim 4, wherein all said face panels are of the same configuration and include three right-angle bends at their opposite ends, with the bend at one end of each panel being slightly larger than that at the opposite end of the same panel, to permit one end of each panel to be nested within the opposite end of the adjacent panel.
Claim 7
Dependent Claim
60 words
The wall structure according to claim 6, wherein all said diagonal panels are of the same configuration, each including a single, acute-angle bend at one end, and a double bend at the opposite end, the inner bend of which forms an obtuse angle to the panel and the outer bend of which forms an acute angle to the inner bend.
Claim 8
Dependent Claim
24 words
The wall structure according to claim 1, wherein said diagonal panels are formed with openings to permit the passage therethrough of the filling material.
Claim 9
Dependent Claim
17 words
The wall structure according to claim 1, wherein said diagonal panels form equal angles to each other.
Claim 10
Dependent Claim
15 words
The wall structure according to claim 1, wherein the wall structure is of linear configuration.
Claim 11
Dependent Claim
15 words
The wall structure according to claim 1, wherein the wall structure is of curved configuration.
