Abstract: Component sets installed at selected intervals along the lengths of upwardly opening, just-below-floor-level utility trenches maintain a substantially parallel-extending relationship between opposed pairs of elongate, upstanding panels that form opposite sidewalls of the utility trench. The component sets each include a pair of elongate uprights of channel-shaped cross-section, and elongate connecting members that bridge between the paired uprights. The connecting members include an upper connecting member having opposite end regions 1) that overlie portions of upper end regions of the uprights, 2) that extending downwardly into the upper end regions of the uprights, and 3) that are snugly received within the upper end regions of the uprights.

Abstract: Component sets installed at selected intervals along the lengths of upwardly opening, just-below-floor-level utility trenches maintain a substantially parallel-extending relationship between opposed pairs of elongate, upstanding sheet metal panels that form opposite sidewalls of the utility trench passageways while concrete is being poured to form concrete floors in commercial and industrial facilities. The component sets include pairs of elongate, metal uprights having channel-shaped cross-sections, and elongate connecting members that bridge between the paired uprights. Pipes, tubes and conduits installed in the utility trenches, and cover plates that overlie and close the utility trenches, are supported by the connecting members.
