Description
Technical Field
The utility model relates to a steel construction installation technique, in particular to steel pipe flexible connection node.
Background
At present, with the rapid development of steel structures in China, the steel structures are widely applied to buildings such as modern industrial plants, warehouses, gymnasiums, terminal buildings and the like. The steel structure has the advantages of concise appearance and convenient processing, and mainly comprises a primary truss and a secondary truss which are of an arch structure and are mainly made of round steel tubes. In the construction of the existing steel structure, the primary and secondary structural connection generally adopts a fixed relevant field welding mode. However, various factors such as large size of relevant linear cuts, cutting errors, installation deformation and the like exist in the construction of the steel structure, so that the primary structure and the secondary structure cannot be normally installed. Usually, the actual size of the field is cut again and the pipe is welded again. The field construction is not flexible, and the working efficiency is low.

Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
The steel pipe telescopic connection joint comprises a main pipe 1 and a branch pipe 2 which are arranged vertically and an adjusting pipe 3 sleeved on the branch pipe 2, wherein the inner diameter and the wall thickness of the adjusting pipe 3 are slightly larger than the outer diameter and the wall thickness of the branch pipe 2, and the adjusting pipe can move on the branch pipe 2 before being welded and fixed so as to realize stepless compensation of axial displacement; after the welded fastening, the outer end of the adjusting pipe 3 is connected to the outside of the main pipe 1, and the inner end thereof is connected to the outside of the branch pipe 2. The end of the inner side of the adjusting pipe 3 is provided with a wave-shaped cut, and the purpose of the design is to increase the welding length and improve the welding strength of the connecting joint. The perimeter of the wave-shaped cut is more than 4 times of the size of the outer diameter of the adjusting pipe.
Preferably, the outer diameter of the main pipe 1 is 10-50 cm; the outer diameter of the branch pipe 2 ranges from 10 cm to 30 cm; the outer diameter of the adjusting pipe 3 ranges from 15 cm to 35 cm. The radial dimensions of the adjusting pipe 3 are chosen to meet the requirement of being freely movable along the branch pipe 2 in order to facilitate the adjustment of the installation length of the branch pipe 2. The adjusting pipe 3 is a round steel pipe or a square steel pipe, has a cross-sectional shape matched with the branch pipe 2, and has a wall thickness 2-6 mm greater than that of the branch pipe 2.
The lap joint length can be flexibly adjusted due to the larger axial displacement compensation capability, the structure is simple, and the installation is convenient and quick; the utility model discloses can greatly improve concatenation efficiency when guaranteeing steel pipe connection construction quality.
Obviously the specific implementation of the present invention is not limited by the above-mentioned manner, and various insubstantial improvements made by the method concept and technical solution of the present invention are all within the protection scope of the present invention. The above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples, and the person skilled in the art can make the adjustment within the scope of the present invention, which all belongs to the protection scope of the present invention.
