Embodiment Construction

[0022] 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.

[0023] like Figure 1 to Figure 7 A piercing chord structure shown includes an end plate group 1 , a web group 2 and a diaphragm group 3 ; the web group 2 and the diaphragm group 3 are both arranged in the end plate group 1 .

[0024] The end plate group 1 has a pair of end plate units parallel to each other, and the end plate unit includes a middle plate 11, an upper side plate 12 and a lower side plate 13; the middle plate 11 has a rectangular structure, and the upper side plate 12 and the lower side plate 13 Welded on the upper and lower sides of the middle plate 11 respectively; the upper side plate 12 includes a first upper bevel 121, a second upper horizontal edge 122, a third upper bevel 123 and a fourth upper bevel 124; the first upper bevel 121 , the second upper ...

Abstract

The invention relates to a novel penetrating chord structure, which is characterized in that it includes an end plate group, a web group and a partition group; the web group and the partition group are both arranged in the end plate group; in the present invention By setting the upper side plate and the lower side plate on the middle plate, the connection nodes of the upper surface and the lower surface of the chord are located on the upper side plate and the lower side; avoid directly connecting with the position of the middle plate, and do not install the zipper There will be interference on the middle plate. Bolt hole groups are set on each connecting node, and the installation position is clear. The chord structure passing through the middle plate increases the strength of the chord and avoids the assembly of the cable and the chord. easily interfered with.

Description

technical field [0001] The invention relates to the field of chord structures, in particular to a piercing chord structure. Background technique [0002] 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 cables makes the distance between the anchor box installation position of the cables and the nodes Due to interference, the nodes and stay cable anchor boxes cannot be properly installed on the chord, so a new chord structure is needed so that the nodes on the chord can be installed without interfering with the stay cables. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a penetrating chord structure, which can solve the problem that the nodes on the chord in the general chord structure are likely to interfere with the cables when they are assembled. [0004] In order to solve the above...
