Problems solved by technology

If the holes are drilled first and then assembled and welded, the positions of the connection holes of the multi-faceted core node chord and other rods will not correspond to each other, which will affect the accuracy of the installation. A new manufacturing method for the multi-faceted core node chord is required. To ensure the accuracy of the installation

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. 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.

[0032] Such as Figure 1-11 As shown, the specific implementation method adopts the following technical scheme: the manufacture of multi-faceted core node chords includes the separate production of each node plate of the multi-faceted core node chord and the assembly and welding of each node plate. The specific steps are as follows:

[0033] S1. Production of gusset plates: including the production of upper horizontal plate un...

Abstract

The invention discloses a method for manufacturing a multifaceted core node chord, which relates to the technical field of bridge engineering. Including the separate fabrication of each gusset plate of the multi-faceted core node chord and the welding and assembly of each gusset plate, specifically the gusset plate production: including the separate fabrication of each gusset plate; the gusset plate and rib assembly welding: the upper horizontal plate unit, the vertical The plate unit and the lower horizontal plate unit are respectively welded with the plate rib; drilling holes on the gusset plate: after the joint plate and the plate rib are assembled and welded, drill bolt hole groups in pairs and positioning holes for each hole group on the gusset plate; assembly: put The upper horizontal plate unit and the vertical plate unit form a groove shape, and then form a box shape with the lower horizontal plate unit. Finally, the secondary parts are assembled in sequence, and the holes are used as the reference for assembly welding. The advantage of the present invention is that: first, the gusset plate and plate ribs are assembled and welded and then drilled in pairs to ensure the centrality and position accuracy of the gusset plate holes; The accuracy of the installation.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a method for manufacturing a multifaceted core node chord. Background technique [0002] The multi-faceted core node chord is located at the lower chord node, and is connected with the stiffening chord, straight web member, diagonal member, flat joint and adjacent lower chord at the same time, which requires high position accuracy. In order to ensure the accuracy of the hole position of the gusset plate of the chord, a reasonable sequence of assembly welding and hole making is very important. If the holes are drilled first and then assembled and welded, the positions of the connection holes of the multi-faceted core node chord and other rods will not correspond to each other, which will affect the accuracy of the installation. A new manufacturing method for the multi-faceted core node chord is required. To ensure the accuracy of the installation. Contents of the inv...
