Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as Figure 7 , Figure 8 As shown, the overall structure of the inserting plate 4 is cross-shaped, and there are shoulders 6 at both axial ends of the inserting plate 4 , and the thickness of the shoulders 6 is equal to the thickness of the backing plate 3 .

[0027] Such as figure 1 , figure 2 , image 3 As shown, there are axial grooves around the butt ends of the first steel pipe 1 and the second steel pipe 2 respectively, the width of the upper side axial groove 8 of the butt end is the width of the upper end of the flashboard 4, and the lower side axial groove 9 of the butt end is close to The width of the butt end is the width of the support pipe 5, the width of the lower axial groove 9 away from the butt end is the width of the lower end of the flashboard 4, and the width of the axial grooves 7 on both sides of the butt end close...

Abstract

The invention relates to abutting-joint and supporting of steel pipes, and aims to provide a connecting part and method for abutting-joint and supporting of single-rail steel pipes. The connecting part comprises a first steel pipe, a second steel pipe, a supporting pipe, an inserting plate and a backing plate. The two ends of the inserting plate are correspondingly embedded into axial troughs of the two abutting-joint steel pipes for solid joint, the backing plate is inserted into a gap of the two sides, and the supporting pipe is inserted into the gap from a bottom groove of the abutting-joint position. According to the connecting part, the two steel pipes are in solid joint through the inserting plate, a variety of internal force such as axial force, bending moment and torque can be transmitted effectively, connecting of the supporting pipe and abutting-joint of the steel pipes are combined, construction is convenient and safe, the process is simple, dependence of connecting quality on technical level of welders is got rid of, and fire hazards can be avoided through a non-welding abutting-joint mode.

Description

technical field [0001] The invention relates to the butt joint and support of steel pipes, in particular to a joint piece and method for the butt joint and support of monorail steel pipes. Background technique [0002] At present, the support of steel pipes usually uses welding technology, and the types of axial connection between steel pipes are usually used: [0003] (1) Welding type: first open a slope at the joint of the two steel pipes, and then weld; [0004] (2) Flange connection type: first weld a flange plate at the butt joint of two steel pipes, and then connect with high-strength bolts. [0005] The advantage of the welded 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 it is easy to induce safety hazards; the advantage of the flange connection type is to avoid the shortcomings of the welded type, but it also has its own shortcomings. : The diameter of the...
