Embodiment 1

[0019] Embodiment one: if Figure 1-4 As shown, the plug-in welded intersecting joint includes a main pipe 1, a branch pipe 2 and an ear plate 3. The main pipe 1 is made of a round steel pipe, the branch pipe 2 is made of a round steel pipe, and the ear plate 3 is made of a solid steel plate. The main pipe 1 is provided with two grooves up and down. The ear plate 3 is inserted into the main pipe 1 through the groove, and is welded with the main pipe 1 by a penetration weld 5; the branch pipe 2 is connected with the main pipe 1 by a first fillet weld 6; the ear plate 3 is provided with a pin hole 4, and the pin shaft Hole 4 is circular hole or oval hole, and the size of bearing pin hole 4 is slightly larger than the bearing pin size of connecting dragline, so that install;

Embodiment 2

[0020] Embodiment two: if Figure 5 As shown, the difference from Embodiment 1 is that two ear plates 3 are provided, the middle row of branch pipes 2 is canceled, and two rows of branch pipes 2 are arranged in total, so as to facilitate the connection of drag cables on the upper and lower sides of the main pipe, and the two parts inserted into the main pipe. 3 common ear plates.

Embodiment 3

[0021] Embodiment three: as Figure 6 As shown, the difference from the embodiment is that a sleeve 8 is arranged outside the main pipe 1 to strengthen the structure, which is suitable for the situation where the structure is under a large force. The two ends of the sleeve 8 and the main pipe 1 pass through the second fillet weld 9 connected to form a laminated pipe, the lug plate 3 and the laminated pipe are connected by penetration welds, and the branch pipe 2 and the casing 8 are connected by fillet welds.

Abstract

The invention relates to an inserting plate type welding through node, comprising a main pipe, a branch pipe and an ear plate. The main pipe can consist of a circular steel pipe or a square steel pipe and can be provided with a sleeve pipe for strengthening when bearing large force. The upper and lower parts of the main pipe are provided with two grooves. The branch pipe can consist of a circular steel pipe or a square steel pipe. The ear plate is provided with a circular hole or an elliptical hole. The ear plate is inserted into a main pipe groove and is and welded on the main pipe. The through line end of the branch pipe is cut by the machine, and the branch pipe is welded on the main pipe. Therefore, the inserting plate type through node is formed. The invention has the advantages of attractive structure appearance, direct and specific force transmission and convenient and simple construction, avoids the problem of increased manufacture cost caused by adopting the casting steel nodes, can sufficiently satisfy the requirement of structure stress, and is especially suitable for the connecting nodes of the pull cable and the main structure in the prestress space structures such as the stayed structures, chord bracing structures and the like.

Description

technical field [0001] The invention relates to a connection node between a cable and a main structure in a prestressed space structure such as a cable-stayed structure and a chord structure in a building structure, and more specifically relates to a plug-in welded intersecting node. Background technique [0002] One of the main nodes in prestressed space structures such as cable-stayed structures and suspensive structures is the nodes connected by cables and structures, and the design of the nodes is the key to the entire structural system. For this type of node, the biggest feature is that the tension end or fixed end of the cable is connected to it, and the design should be convenient for installation and tension. Commonly used joints in engineering include bolted ball joints, welded hollow ball joints and intersecting joints. The bolt ball joint is not suitable for welding a steel pipe or ear plate to connect the cable, and direct anchoring with the cable will cause str...
