Corner connection for temporary shoring

Abstract

A connection arrangement for temporary shoring in an excavation site is used to secure I-beams together at corners within the excavation site. Typically, four I-beams are connected together to form a rectangular frame that is suspended within the excavation for bracing the shoring walls thereof. However, any polygonal shape may be used. The connection arrangement includes mating socket or connecting members which are placed over the ends of I-beams to be fastened together. One of the connecting members includes an outwardly extended tab while the other includes a pair of outwardly extended tabs. The first outwardly extending tab fits between the two extending tabs of the corresponding connecting member. All of the tabs are provided with apertures which are placed in alignment when the connection is made so that a bolt or pin can be passed through the apertures to secure adjacent connecting members together. Each connecting member also includes a large eyelet for receiving a chain or other elongated supporting member which is typically used to suspend the resulting I-beam frame at a desired height within the shoring wall. Alternative embodiments provide for a secondary bar attached to the connectors to provide additional support. Also numerous beam/connector arrangements may be provided at different heights within a single excavation site. Such an arrangements provide much greater support for the side walls of the excavation site.
