Construction beam connection device

Abstract

A construction beam connection device includes an abutment member, a connection member positioned under the abutment member and a threaded assembly fixedly connected with the abutment member and extending through the connection member. The connection device can be directly mounted at the junction between beams. The threaded assembly serves to fasten the abutment member to the connection member so as to securely connect the construction beams with each other. Accordingly, the safety in working can be ensured and the working is facilitated.
