Embodiment
[0031] Such as Figure 1-Figure 3 As shown, this embodiment provides a web member structure of a concrete-filled steel tube truss-type main arch, including a web member assembly 2;
[0032] The number of web member assemblies 2 is several groups, several groups of web member assemblies 2 are arranged in the same direction, and adjacent web member assemblies 2 are fixedly connected;
[0033] The web bar assembly 2 includes a transverse web bar 21 and two diagonal web bars 22, and the transverse web bar 21 and the two diagonal web bars 22 are sequentially connected end to end and form a triangular unit;
[0034] The two ends of the transverse web bar 21 are respectively used to be perpendicular to the upper chord 11 and the lower chord 12 of the main arch 1, and one end of one diagonal web bar 22 is used to connect with the upper chord 11 of the main arch 1 on the corresponding side. The other end of the diagonal web rod 22 is connected to the midpoint of the transverse web rod...
