As shown in fig. 4, fig. 5 and fig. 6, each toothed plate 2 comprises a rectangular positioning plate 21, the opposite sides of the two ends of the positioning plate are respectively connected with a first angle steel 22 and a second angle steel 23, wherein one outer side surface of one side of the first angle steel is welded with the positioning plate, the other side of the first angle steel is flush with one end of the positioning plate and is provided with two screw holes 221, the other end of the positioning plate is provided with two reinforcing bar protection layer thickness adjusting holes 211 which are distributed along the transverse direction of the positioning plate, each reinforcing bar protection layer thickness adjusting hole 211 is a longitudinal bar-shaped hole along the positioning plate, one side of the second angle steel 23 is provided with two second angle steel adjusting bolts 24 in a penetrating manner, the two second angle steel adjusting bolts respectively penetrate through the two reinforcing bar protection layer thickness adjusting holes 211 on the positioning plate and are screwed with nuts to fix the second angle steel 23 and the positioning plate 21, and the other side of the second angle steel 23 faces towards one end of the positioning plate, which is connected with the first angle steel.
As shown in fig. 1, 7, 8 and 9, two screw holes on the first angle bar 22 of each toothed plate penetrate two first angle bar fixing bolts 25, and the two first angle bar fixing bolts 25 respectively penetrate a pair of main bar interval adjusting holes 11 on the main beam and are screwed with nuts to fix the first angle bar 22 and the main beam 1.
The invention positions the cable tower main reinforcement through each toothed plate. In the structure, the central distance between two adjacent pairs of main rib distance adjusting holes on the main beam is set according to the design distance of the main ribs of the cable tower, the first angle steel adjusting bolt 25 on each toothed plate can slide along the main rib distance adjusting holes 11 to adjust the distance between two adjacent toothed plates, so that the main rib distance can be adjusted as required when the cable tower embedded part and the template pull rod are installed; the second angle steel adjusting bolt 24 can slide along the thickness adjusting hole 211 of the steel bar protecting layer to adjust the position of the steel bar on the outer layer of the cable tower, so that the thickness of the steel bar protecting layer of the cable tower can be adjusted.
As a specific embodiment of the invention, the center distance between two adjacent pairs of main bar distance adjusting holes is set to be 15cm, and the length of each main bar distance adjusting hole is 5cm, so that the distance adjusting range of the adjacent main bars in each layer of steel bars is 10-20cm; the length of the steel bar protective layer thickness adjusting hole is set to be 5cm, and the position of the steel bar on the outer layer of the cable tower can be adjusted within the range of 5cm.
