Abstract

The utility model discloses a butt joint part using an axial cross insertion plate to enable steel tubes to be in butt joint. Ends of the cross insertion plate are respectively embedded into axial cross grooves of the steel tube by the butt joint ends of two steel tubes to be fixedly connected, the other ends of the steel tubes not embedded into the axial cross grooves of the steel tubes are integrated with the other end of the cross insertion plate through angle steel, or butt joint ends of the two steel tubes are at least in serial with a middle steel tube. Two steel tubes form rigid connection through a cross insertion plate butt joint type, the butt joint part can effectively transmit all inner force of axial force, bending moment, shearing force, torsion and the like, the butt joint part is convenient and safe to construct, and on-site installation of steel tubes uses non-welded bolt connection so as to be convenient to install, remove the problem that connection quality relies on technical level of welding workers and avoid fire hazards due to a non-welding working mode. The butt joint part is wide in application scope. The cross insertion plate butt joint type can be used for axial connection between similar multiple sections of steel tubes and axial connection between different steel tubes with different outer diameters, cross section shapes, wall thicknesses and the like.
