A bulk material supporting wall comprises at least two beams arranged at an angle to one another and connected in a form-locking or material-locking manner. One beam is a longitudinal beam extending substantially parallel to the wall plane and the other is a cross beam extending at an angle to the longitudinal beam. The first beam comprises at least two profile legs arranged at an angle to one another. The first profile leg forms a bulk material bearing surface which covers the central part of the longitudinal beam's cross section. The second profile leg forms a bulk material retaining surface which faces the inside space of the frame and is arranged offset to the outside of the frame with respect to the bearing surface and at an angle to the bearing surface. The first profile leg has a wedge-shaped cross-section and a substantially plane bottom surface forming the underside of the wedge-like cross-section. The bearing surface which forms the upper side of the first profile leg is also of substantially plane shape such that the cross-sectional height of the first profile leg increases evenly from the outside inwards. This design combines enhanced internal stability of the wall against force and bending moments exerted by the bulk material filling.
A supporting grid wall for a bulk material filling defining a generally vertically extending wall plane and a frame plane extending transversely thereto, comprising at least two beams arranged at an angle to one another and connected in a form-locking or material-locking manner, one of said beams being a longitudinal beam extending substantially parallel to the wall plane and comprising at least two profile legs arranged at an angle to one another, said first profile leg having at least one bearing surface for the bulk material filling covering substantially the central part of the longitudinal beam's cross-section, and said second profile leg having a retaining surface for the bulk material filling facing the inside space of the frame, offset to and disposed at an angle to the outside of the frame with respect to the bearing surface for the bulk material filling, characterized in that said first profile leg has a wedge-shaped cross-section with a cross-sectional height which increases evenly from the outside inwards.
A frame for a planar supporting grid wall having a bulk material filling, comprising at least two beams arranged at an angle to one another and connected in a form-locking or material-locking manner, one of said beams comprising a longitudinal beam extending substantially parallel to the plane of said wall and having two profile legs arranged at an angle to one another, a first one of said profile legs having a one bearing surface for the bulk material filling covering substantially the central part of said longitudinal beam's cross-section, and a second one of said profile legs forming a retaining surface for the bulk material filling facing inwardly of said frame and spaced outwardly from said bearing surface for the bulk material filling, said retaining surface being disposed at an angle to said bearing surface, said first profile leg having a wedge-shaped cross-section and a substantially planar bottom surface forming the underside of said wedge-like cross-section, said bearing surface forming the upper side of said first profile leg and being also substantially planar whereby the cross-sectional height of said first profile leg increases evenly in a direction from the outside of said frame inwards.
