Description
Technical Field
The invention relates to a joint connecting structure design, in particular to a steel pipe joint with a central circular plate in through connection.
Background
The tube plate connecting node is an external stiffening plate connecting node, and the structural steel tube is connected with the secondary member steel tube together through welding. In general, a main structure in a power transmission tower is a large-diameter structural steel pipe, and in order to join a small-sized secondary member, the end of the secondary member is not directly joined to the main structural steel pipe, but a steel plate with a slightly large size is welded to the main structural steel pipe, and the secondary member is further joined to the plate in a bolt manner. Compared with the way that each secondary member is respectively jointed to the main structure in a point mode, the mode of integrating each secondary member node through the plate member unit not only forms secondary member joints with clear layers on the main structure, but also clears the jointing logic between the primary member and the secondary member.
The tube plate nodes can be divided into stiffening plate tube plate nodes and non-stiffening plate tube plate nodes according to the reinforcing condition. The stiffening plate may be a ring-shaped plate, a semi-ring-shaped patch, an 1/4 ring-shaped patch, a 1/6 ring-shaped patch, a 1/8 ring-shaped patch, or the like.
The branch pipe and the gusset plate can be welded together after being grooved and can also be connected by adopting a plug board connector, and the type of the plug board can be divided into: u-shaped plate, T-shaped plate, I-shaped plate (single plug board), cross plate and groove plate. U type plate joint is used for the great material of atress, and T type plate joint is used for supplementary material, and I type plate joint is used for the less supplementary material of atress etc. and groove type plate joint is used for atress material, supplementary material etc. ten type plate joints are used in than U type plate joint or under the condition that groove type plate joint bolt is in large quantity. Each bayonet joint type is shown in figures 1 and 2.
The pipe plate connection node and the hollow interlayer steel pipe concrete node which are used as key parts of the power transmission line steel pipe tower are intersected, the stress state is very complex, and the stress concentration phenomenon is very obvious. The experimental research and theoretical analysis aiming at the aspect are not fully developed at home and abroad. At present, research results aiming at hollow steel pipe joints with direct intersecting welding connection of branch pipes and main pipes are relatively complete, and the results have relatively strong guidance and operability on the design of the intersecting welding connection joints of the steel pipe tower. However, although some researchers at home and abroad have studied the ultimate bearing capacity of hollow tube nodes connected by node plates, in general, related test data and theoretical analysis data are still very lacking, and although design guidelines of some foreign building associations have design formulas for such nodes, basic data and data of research are still incomplete, and the research on the adaptability of the nodes to a large number of parameter changes is not mature, and the adoption of japanese specifications is not appropriate due to differences in steel properties and steel tube models. The steel structure specification of China is blank for the design rule of the node.

Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The steel pipe node with the central circular plate connected in a penetrating way comprises a central circular plate 3 and a main pipe 1, wherein the central circular plate 3 penetrates through the pipe wall of the main pipe 1, and two sides of the central circular plate 3 are respectively connected with a branch pipe 2; the central circular plate 3 and the main pipe 1 are connected in a welding mode.

Still be equipped with polygon gusset plate 5 on being responsible for 1, branch pipe 2 still passes through the notch and welds with polygon gusset plate 5. The polygonal gusset plate 5 and the main pipe 1 are connected in a welding manner. The connection between the polygonal gusset plate 5 and the main pipe 1 respectively forms a top and a bottom of a gusset area, and the top and the bottom of the gusset area are respectively provided with an annular ear plate 4.
The steel pipe joint mainly aims at a steel pipe joint which is connected with a central circular plate in a penetrating mode and can be widely applied to a high-rise power transmission tower.
In order to improve the processing work efficiency and the processing quality of the steel tube tower, the steel tube nodes adopt standardized and serialized designs. The connection mode of the notch welding can give full play to the advantages of high bearing capacity and high rigidity of the welding connection for the oblique material with larger stress. The juncture of the intersection of the central circular plate and the steel pipe is a weak link of the node, and when the node integrally enters a plastic stage and continues to be loaded, the displacement of the node is rapidly increased and the node enters a plastic failure state. Therefore, the central circular plate is adopted to run through the main pipe, the bearing capacity of the node is greatly improved, and the node is safe and reliable.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
