Embodiment 1

[0073] Using the batch welding method of the above steel structure TKY joints, such as Figure 6 and Figure 7 As shown, it is used for the positioning and support of the main pipe 1 and its welded branch pipe 2 at its node. The TKY node assembly tooling includes two steel pier 3 and branch pipe support pier 4. The two steel pier 3 are used for the positioning of the main pipe 1. and the supporting main pipe 1 are placed horizontally; if figure 2 and image 3 As shown, the steel pier 3 includes an "I"-shaped base seat 30 and two pairs of symmetrically distributed on both sides of the top of the "I"-shaped base seat 30, which are used to support the main pipe 1 according to the diameter of the main pipe 1. Support and position the fixed arc-shaped baffle 31, the arc-shaped surface of the arc-shaped baffle 31 is set close to the outer wall of the main pipe 1, and the upper and lower sides of the "I"-shaped base frame seat 30 are welded to the top surface and the bottom respec...

Embodiment 2

[0084] Such as Figure 10 and Figure 11 As shown, the difference from Embodiment 1 is that in the TKY node assembly tooling, four branch pipe support piers 4 are used to respectively fix and support the four branch pipes 2 at the node of the main pipe 1, and the branch pipe support piers 4 include supporting and fixing The support seat 40 placed obliquely on the branch pipe 2 and the thrust stopper 41 positioned against the outer end of the branch pipe 2 along the opposite direction of the branch pipe 2 axial direction relative to the other end of the branch pipe 2 node, the support seat 40 and the thrust stopper 41 is fixed on the same bottom plate 42; the supporting seat frame 40 is set close to the node side of the branch pipe 2, and the thrust block 41 is located outside the supporting seat frame 40 along the axial direction of the branch pipe 2; the supporting seat frame 40 is formed to cooperate with the outer wall of the branch pipe 2 The arc-shaped support groove 400...

Abstract

The invention discloses a batch welding method for steel structure TKY joints. The batch welding method is used for welding a main pipe and short joint branch pipes at the TKY joints of the main pipe. The batch welding method comprises the following steps of S100, calculating and simulating branch pipe space angles for the different TKY joints of the main pipe; S200, designing and manufacturing a TKY joint assembly tool according to the space angle of the branch pipes at the TKY joints; S300, carrying out precision measurement and control on the TKY joint assembly tool; S400, positioning and scribing of the TKY joint assembly tool; S500, in-place and pairing of TKY joint pipes; and S600, TKY joint welding. Batch manufacturing of the TKY joints is achieved, one-time assembly forming is guaranteed, the number of times of measurement and the size control difficulty are reduced, the requirement for assembly welding work of the TKY joints of the same specification on a large scale is met, batch and high-speed production is achieved, and production efficiency is improved.

Description

【Technical field】 [0001] The invention relates to jacket construction welding technology, in particular to a batch welding method for steel structure TKY nodes. 【Background technique】 [0002] Steel structures have been widely used in construction industry, mining machinery, military engineering, marine engineering and offshore wind power due to their advantages of high strength, good toughness, high rigidity, small footprint and beautiful appearance. In some steel structure buildings, tubular joints are often used, especially tubular joints in the form of TKY. Steel structure TKY joint is a kind of pipe intersection joint, which can be divided into three types: T, K, and Y according to the spatial shape of the pipe. This joint structure is widely used in the field of marine engineering, especially in steel structures such as jackets. The stability and safety of the steel structure mainly depend on the construction accuracy and construction quality of the TKY joints. In th...
