[0041] In this embodiment: the connecting rod 16 plays a supporting role during the pouring process, which avoids excessive pressure of cement on the outside of the embedded part 1, which would cause the embedded part 1 to deform and affect the installation of the cable tray 6.

[0042] Please see Figures 1-4 In the diagram, groove 2 13 and groove 3 14 are interconnected. The center lines of groove 2 13, groove 3 14 and cable tray 6 are on the same vertical line. There are two sets of limit strips 8 of the same specification. The limit strips 8 are distributed at equal intervals on the cable tray 6.

[0043] In this embodiment: the limiting strip 8 sets a constraint on the cable in the cable tray 6. The cable extends through the cable tray 6 at the top of the embedded part 1 through the second groove 13 and the third groove 14 to the interior of the cable tray 6 at the bottom of the embedded part 1, realizing the interconnection of cables between the upper and lower floors.
