Description

Connector and method for steel pipe butt joint and support

technical field

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

At present, the support of steel pipes usually uses welding technology, and the types of axial connection between steel pipes are usually used:

(1) Welding type: first open a slope at the joint of the two steel pipes, and then weld;

(2) Flange connection type: first weld a flange plate at the butt joint of two steel pipes, and then connect with high-strength bolts.

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 flange is larger than that of the steel pipe, and the larger-sized protruding edge formed will affect the layout of other mechanisms and the overall structure.

Contents of the invention

In order to solve the potential safety hazards in the welding technology in the background technology and the problem of oversized connection parts, the purpose of the present invention is to provide a connecting piece and method for butt jointing and supporting of monorail steel pipes.

For solving technical problem, solution of the present invention is:

The connecting piece based on the butt joint and support of the steel pipe includes the butt joint part of the steel pipe and the support part of the steel pipe, the butt joint part of the steel pipe includes the first steel pipe, the second steel pipe, an inserting plate and a backing plate, and the overall structure of the inserting plate is a cross shape, There are shoulders at both axial ends of the inserting plate, and the thickness of the shoulders is the thickness of the backing plate. The butt end of the first steel pipe and the second steel pipe are respectively provided with axial grooves around the butt end, the width of the axial groove on the upper side of the butt end is the width of the top of the plugboard, and the width of the axial groove on the lower side of the butt end is close to the butt end. The width of the support tube, the width of the axial groove on the lower side away from the butt end is the width of the lower end of the insert plate, the width of the axial grooves on both sides of the butt end close to the butt end is the sum of the thickness of the backing plate and the thickness of the side end of the insert plate, away from the butt joint The width of the end is the sum of the width of the notch near the butt end and the thickness of the shoulder.

The supporting part of the steel pipe includes a supporting pipe. The supporting end of the supporting pipe has end grooves on the two sides parallel to the butt joint surface. The width of the end groove is the width of the lower end of the inserting plate, and the depth of the end groove is the axis The distance between the bottom of the groove near the butt end and the bottom of the butt pipe.

Compared with background technology, the beneficial effect that the present invention has is:

(1) The mechanical performance of the joint of the steel pipe is good. The two steel pipes are butted by the inserting plate to form a rigid connection, which can effectively transmit various internal forces such as axial force, bending moment, and torque.

(2) The construction is convenient and safe, and the connection quality is easy to control. The butt joint and support of the steel pipe adopt a non-welding method, which is not only convenient for construction and installation, but also gets rid of the dependence of the joint and support quality on the technical level of the welder. At the same time, the non-welding working method can avoid fire hazards.

(3) Combine the butt joint of the steel pipe with the support at the joint. Suitable for monorail connections over long distances.

(4) The butt joint of the steel pipe does not increase the pipe diameter area. No protruding edge with a large size is formed so as not to affect the arrangement of other mechanisms and the beauty of the overall structure.

detailed description

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

As shown in FIG. 7 and FIG. 8 , 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 .

As shown in Fig. 1, Fig. 2 and Fig. 3, axial grooves are respectively opened around the butt ends of the first steel pipe 1 and the second steel pipe 2. The width of the lower side axial groove 9 near 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 plugboard 4, and the width of the axial grooves 7 on both sides of the butt end near the butt end is The sum of the thickness of the backing plate 3 and the thickness of the side end of the insert plate 4, and the width away from the butt end is the sum of the width of the notch near the butt end and the thickness of the shoulder 6.

The supporting part of the steel pipe includes a first steel pipe 1, a second steel pipe 2 and a support pipe 5. The support end of the support pipe 5 is provided with an end groove 10 on two sides parallel to the butt joint surface, and the width of the end groove 10 is about 4.
