Abstract

The bracket described herein comprises a device for supporting and holding the sidewall of a conduit trench. These conduit trenches are designed to lie on the ground or may be submerged with the top at ground level. Pipe, conduit, electrical cables, etc. may be laid in the trench with the sidewalls held in place by this new bracket. The bracket comprises two angle irons spaced parallel to each other and fastened to each other by crosspieces at the ends thereof. The angle irons have slots or grooves at each end thereof into which the flat base of a vertical member may be inserted. The flat piece of this base is inserted into the pair of slots or grooves to the end of the angle irons where the crosspiece will stop the movement of the vertical piece. The crosspiece serves as a base for the retaining wall and the vertical piece of the bracket holds the wall in a vertical position.

Dependent claims

In a channel construction suitable for laying conduit, pipe and electrical cable on or below-ground level wherein slabs are provided as sidewalls with a bracket adapted to hold said sidewall slabs, the improvement in said bracket comprising:

A. a base element comprising two arms, each having a length corresponding approximately to the outer dimension of said channel which includes the thickness of said sidewall slabs, said arms being spaced from and parallel to each other, with the adjacent ends of said two arms being rigidly fixed to each other by a crosspiece and having a configuration which provides a groove between said crosspiece and said arm at the end position thereof;
and
B. a vertical element comprising a horizontal base with two vertical arms rising vertically at a 90.degree. angle with said base, with the lower ends of said arms rigidly fixed to said base, said two vertical arms being spaced from and parallel to each other, and two cross-pieces rigidly fixed to and flat against said vertical arms and at the ends thereof;
said base having two parallel edges so spaced from each other and of a size that will fit in the said grooves of said base element whereby upon said base edges being fitted into said grooves, one or two of said vertical elements will be supported vertically in such a manner that said slabs may be supported vertically thereon.
