Abstract

The invention discloses a method for realizing butt joint of steel pipes by the aid of an axial cross plug board and a butt joint part. Two end of the cross plug board is embedded into steel pipe axial cross recesses at butt joint ends of the two steel pipes, the other ends, which are not embedded into respective the steel pipe axial cross recesses of the two steel pipes, of the cross plug boards are integrally in butt joint with angle steel, or at least one intermediate steel pipe is further serially connected between the butt joint ends of the two steel pipes. The two steel pipes are connected rigidly in a cross plug board butt joint mode, various internal force including axial force, bending moment, shearing force, torque and the like can be effectively transmitted, construction is carried out conveniently and safely, the steel pipes can be connected by bolts without welding an a field installation process, construction installation is carried out conveniently, the connection quality does not rely on the technical level of welding workers, fire hazards can be avoided due to a non-welding working mode, the method is wide in application range, multiple steel pipes in the same type can be axially connected in the cross plug board butt joint mode, and different types of steel pipes with different outer diameters, different section shapes, different wall thickness and the like also can be axially connected in the plug board butt joint mode.

Description

technical field [0001] The invention relates to steel pipe connectors, in particular to a method for butt-joining steel pipes with an axial cross plate in a building structure and the butt joint. Background technique [0002] The usual types of axial connection between steel pipes are: (1) Welding type: first open 35~45mm at the butt joint of two steel pipes ° (2) Flange connection type: first weld a flange at the butt joint of two steel pipes, and then connect with high-strength bolts. The advantage of the welding type is that the structure is good, and the disadvantage is that the welding quality control is highly dependent on the technical level of the operator and there is a potential fire hazard. The advantage of the flange connection type is that it avoids the disadvantages of the welding type, but the disadvantage is that the diameter of the flange is larger than that of the steel pipe, and the formed larger-sized protruding edge will affect the layout of other rods ...
