Abstract
A panel for supporting the sidewalls of an excavation includes a plate, longitudinal members and vertical members. Each longitudinal member includes a first leg extending along the length, substantially parallel to and spaced laterally from the plate. The first leg of each longitudinal member being located adjacent and secured to the first leg of another member. A second leg, integral with the first leg, extends along the length, away from the first leg and toward the plate, the second leg being secured to the plate. Axially spaced vertical members are welded to the plate and to the longitudinal members.
Claims11
A panel for supporting the sidewalls of an excavation, comprising:
- a seamless, single-piece flat plate having a width, a length, an inner surface and an outer surface;
- multiple longitudinal members being stacked, each longitudinal member is a unitary, one-piece member having a cross-section consisting of an L-shape, wherein the L-shape cross-section has a bend with first and second legs, each leg having an outer longitudinal edge, the first leg extending along the length and along a portion of the width, substantially parallel to and spaced laterally from the single-piece plate, the first leg of each longitudinal member being located and secured at its outer longitudinal edge by a weld to the first leg at the bend of an adjacent L-shaped longitudinal member, the second leg to the longitudinal member extends along the length, away from the first leg and toward the single-piece plate, the second leg being secured at its outer longitudinal edge by a weld to the inner surface of the single-piece plate;
- and
- a lower edge member extending along a portion of the width, secured by a first lower edge weld to a first leg of a lowermost longitudinal member, inclined toward and secured by a second lower edge weld to the single-piece plate to form a wedge with the plate that extends along the length, the wedge having a tip located at a lower edge of the panel.
A panel for supporting the sidewalls of an excavation comprising:
- a seamless, single-piece flat plate having a width, a length and inner and outer surfaces;
- multiple longitudinal members, each longitudinal member being a unitary, single piece having a cross-section consisting of an L-shape, wherein the L-shape cross-section includes:
- a bend;
- a first leg extending along the length and along a portion of the width, substantially parallel to and spaced laterally from the single-piece plate, the first leg of each longitudinal member having an outer longitudinal edge spaced from the bend, the outer longitudinal edge of the first leg being secured by a weld to the first leg at the bend of an adjacent member;
- and
- a second leg integral with the first leg, extending along the length, away from the first leg and toward the single-piece plate, and the second leg having an outer longitudinal edge spaced from the bend, the outer longitudinal edge of the second leg being secured by a weld to the inner surface of the unitary, single-piece plate.
