Embodiment Construction

[0045] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0046] Such as figure 1 Shown is a double anchor box type external node chord manufacturing method, the double anchor box external node chord according to S1. blanking; S2. machining; S3. plate drilling; S4. web material, machine Processing; S5. Assembly welding plate unit; S6. Chord assembly welding;

[0047] S1. Blanking: The blanking plate is pretreated by the pretreatment line. For irregular shape parts, the CNC cutting machine is used for blanking. When blanking, the machining amount is reserved for the main edges and welding edges that need to be machined. The blanked parts are general parts, mainly including: beam web joint plate 5, transverse diaphragm 10 and anchor box bearing plate 41;

[0048] S2. Machining:

[0049] S2.1 Machining the web butt joints, includi...

Abstract

The invention relates to a manufacturing method of a double-anchor box type external node chord member. The double-anchor box type external node chord member is manufactured according to the steps of S1) blanking, S2) machining, S3) flat plate drilling, S4) web receiving and machining, S5) plate unit assembly welding and S6) chord member assembly welding. As nodes are mounted out of anchor boxes connected with stay cables on the chord member to avoid from the connecting places between the anchor boxes and the stay cables, the anchor boxes cannot be interfered with the nodes, the installation of the stay cables of a bridge and the welding of node plates are not mutually interfered, and the construction progress of the bridge is guaranteed.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a method for manufacturing a double-anchor box type external node chord. Background technique [0002] In bridge engineering such as Wuhu Bridge, when it comes to the chords on cable-stayed bridges, the stay cables are connected to the chords. Since nodes are also installed on the chords, the tension angle required by the stay cables makes the stay cables The interference between the installation position of the anchor box and the node causes the node and the anchor box of the cable-stayed cable to be installed on the chord reasonably. Therefore, a new method of making the chord is needed so that the anchor box and the node on the chord can be installed and There will be no interference. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double anchor box type external node chord manufacturing method, which can solve...
