Combination wall with tube pile connectors
View Patent ↗A combination wall ( 10 ) for supporting the ground comprises at least two tubular piles ( 12 ) adapted to be rammed at least part way into the ground and a wall element ( 14 ) inserted between two respective adjacent tubular piles ( 12 ). The wall element ( 14 ) is provided with interlocks ( 22 ) that are used to engage the wall element ( 14 ) with interlock profiles ( 18 ) that are provided on the tubular piles ( 12 ). The wall element ( 14 ), when hung between the tubular piles ( 12 ), is designed as a segment of a circle with an at least approximately circle-segment-shaped cross-section.
1. A combination wall for supporting the ground comprising at least two tubular piles adapted to be rammed into the ground and a wall element inserted between two respective adjacent tubular piles, said tubular piles being provided with first interlock profiles that are used to hang the wall element by interlocking second interlock profiles that are provided on the wall element, said first and second interlock profiles defining an interlock connection when engaged, wherein the wall element that is hung between the tubular piles is formed as a segment of a circle with an at least approximately circle-segment-shaped cross-section having a maximum arc length of approximately 180° ; and wherein the interlock connection between the circle-segment-shaped wall element and each respective tubular pile comprises (1) the second interlock profile with a claw having a C-shaped cross-section, the C-shaped claw being formed by two mirror-symmetrical claw strips that protrude from a weld-on base with the free ends thereof defining an interlock jaw and enclosing an inner interlock chamber with an at least approximately circular or oval cross-section, and (2) the first interlock profile with a head strip that engages with the C-shaped claw, the first interlock profile having the head strip formed at the free end of a neck strip which protrudes from a weld-on base, wherein the thickness of the neck strip, viewed perpendicular to its longitudinal direction, is dimensioned smaller than the width of the head strip perpendicular to the longitudinal direction of the neck strip; wherein the weld-on base of the second interlock profile provided with the C-shaped claw is welded to the circle-segment-shaped wall element adjacent a flat side of a longitudinal edge thereof, such that the C-shaped claw with its interlock jaw points away from the flat side of the longitudinal edge in one of (a) a tangential and (b) a radial direction, respectively, of the circle-segment-shaped wall element; and wherein a weld-on strip protrudes from the weld-on base of the second interlock profile.
2. A combination wall as defined in claim 1 , wherein the wall element that is hung between the tubular piles is a tube circle segment with an at least approximately round cross-section.
3. A combination wall as defined in claim 1 , wherein the outside of the outward curved circle-segment-shaped wall element is arranged between the tubular piles such that the section of the outside of the wall element that is located furthest out runs in a common line with the sections of the two tubular piles that are located furthest out.
4. A combination wall as defined in claim 1 , wherein the weld-on strip that protrudes from the weld-on base of the weld-on profile is welded to a lateral surface of the circle-segment-shaped wall element or to a longitudinal edge thereof itself when the C-shaped claw points in the tangential or radial direction, respectively.
5. A combination wall as defined in claim 4 , wherein the weld-on strip is a substantially straight strip that protrudes at a right angle from the weld-on base of the second interlock profile.
6. A combination wall as defined in claim 1 , wherein the length of the neck strip viewed in its longitudinal direction corresponds to a multiple of the thickness of the head strip when viewed in the longitudinal direction of the neck strip.
7. A combination wall as defined in claim 6 , wherein the multiple is in the range of 4 to 6.
8. A combination wall as defined in claim 6 , wherein the multiple is 1.
9. A combination wall as defined in claim 1 , wherein the tubular piles exhibit an at least approximately round cross-section.
10. A combination wall as defined in claim 9 , wherein the curvature radius of the circle-segment-shaped wall elements corresponds at least approximately to the curvature radius of the tubular piles.
11. A combination wall as defined in claim 1 , wherein at least a portion of the tubular piles is produced from used pipeline tubes.
12. A combination wall as defined in claim 1 , wherein at least a portion of the circle-segment-shaped wall elements is produced from used pipeline tubes.
13. A combination wall as defined in claim 1 , wherein the weld-on strip is arranged on the inside surface of the circle-segment-shaped wall element.
