Abstract

A shoring beam extension and reinforcement assembly allows a user to removably connect a plurality of shoring beams together so as to customize a support assembly to a particular excavation site. In use, main shoring beams extending around the periphery of an excavation site are connected at the corners by corner connections and are connected along the longitudinal sides of the excavation site by the extension of reinforcement assembly. Additionally, the first and second connectors support a center shoring beam laterally across the excavation site. The assembly is provided with additional support by tabs extending from each of the first and second connectors. Reinforcing beams include tabs having apertures adapted to align with apertures in the tabs of the first and second connectors such that connecting pins may be inserted there through to connect the reinforcing beams with the connectors. Eyelets located on the first and second connectors provide a means by which the assembly may be supported.

Dependent claims

A temporary shoring arrangement including upstanding wall portions positioned within an excavation site and braced by a plurality of shoring beams including a first shoring beam having a first end and a second end, and a second shoring beam having a first end and a second end, the temporary shoring arrangement comprising:

a shoring beam extension and reinforcement assembly comprising:
a center shoring beam having a first end and a second end;
a first connector including:
a first hollow box portion formed along a first longitudinal axis and having an opening situated at one longitudinal end of said first hollow box portion wherein said first hollow box portion is adapted to slidably receive, through said opening, the first end of the first shoring beam, and a first tab extending from the first hollow box portion including an aperture therein;
a second hollow box portion formed along the first longitudinal axis and having an opening situated at one longitudinal end of said second hollow box portion, wherein said second hollow box portion is adapted to slidably receive, through said opening, the first end of the second shoring beam, and wherein the second hollow box portion is connected to the first hollow box portion, defining a main body portion of the first connector, and a second tab extending from the second hollow box portion including an aperture therein;
a third hollow box portion formed along a second longitudinal axis and having an opening situated at one longitudinal end of said hollow box portion, the third hollow box portion extending laterally from said main body portion, wherein said third hollow box portion is adapted to slidably receive, through said opening, the first end of the center shoring beam, and third and fourth tabs extending from the third hollow box portion and including respective apertures therein;
and
a first reinforcing beam adapted to connect to the first shoring beam and the center shoring beam.
