Example Embodiment

[0019] Example one: such as Figure 1-4 As shown, the plug-in welded intersecting node includes a main pipe 1, a branch pipe 2 and an ear plate 3. The main pipe 1 uses a round steel pipe, the branch pipe 2 uses a round steel pipe, and the ear plate 3 uses a solid steel plate. The main pipe 1 is provided with two grooves up and down. The lug plate 3 is inserted into the main pipe 1 through the slot, and is welded to the main pipe 1 by a penetration weld 5; the branch pipe 2 and the main pipe 1 are connected by a first fillet weld 6; the lug plate 3 is provided with a pin hole 4, a pin shaft The hole 4 is a round hole or an elliptical hole, and the size of the pin hole 4 is slightly larger than the size of the pin connecting the cable to facilitate installation; there are three rows of branch pipes 2 on the main pipe 1, and three branch pipes 2 in each row.

Example Embodiment

[0020] Embodiment two: such as Figure 5 As shown, the difference from the first embodiment is that two ear plates 3 are provided, and the middle row of branch pipes 2 is eliminated, and a total of two rows of branch pipes 2 are provided. It is convenient to connect cables on the upper and lower sides of the main pipe and insert the two parts of the main pipe. The ear plate 3 is shared.

Example Embodiment

[0021] Example three: such as Image 6 As shown, the difference from the embodiment is that a sleeve 8 is provided outside the main pipe 1 to strengthen the structure, which is suitable for situations where the structure is stressed. Both ends of the sleeve 8 and the main pipe 1 pass through a second fillet weld 9 Connected to form a superimposed tube, the lug plate 3 and the superimposed tube are connected by penetration welds, and the branch tube 2 and the sleeve 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...
