The crossbeam 2 is made of HW250×250H steel, and the length of the crossbeam 2 is 4.0 meters. The columns are also made of hot-rolled H-steel. In order to ensure that the rack has sufficient bearing capacity, HW175×175H steel is used during production, and the column height is 3.0 meters. Connecting blocks 3 that are clamped with the base frame 1 are connected to both sides of the bottom of the crossbeam 2, and a slide groove that is clamped with the upper part of the H-steel is arranged on the inner side of the connecting block 3, and a locking screw for fixing with the crossbeam 2 is arranged on the outer side of the connecting block 3. The position of the crossbeam 2 on the base frame 1 can be adjusted by loosening the locking screw.

[0025] like Figure 2 As shown, a connecting base plate 5 is provided at the bottom of the column 4, and the connecting base plate 5 is adjusted and fixed with a plurality of adjusting bolt holes 7 opened on the beam 2 through connecting bolts 6. In order to ensure that the tire frame is suitable for pier column steel bars 20 of different cross-sectional sizes, adjusting bolt holes 7 are respectively provided at the tops of both ends of the beam 2 according to pier columns of different specifications, and the bolt hole spacing is 10 cm. In this way, the spacing can be appropriately adjusted according to the size and weight of the pier column steel bars to be processed.

[0032] like Figure 4As shown, the adjustable diagonal brace 19 is provided with a length-adjustable basket bolt, the screw rods at both ends of the basket bolt are respectively hingedly connected to the corresponding cross beam 2 and column 4, and the verticality of the column 4 on both sides of the baffle 18 is adjusted by rotating the basket bolt, thereby ensuring the verticality of the baffle 18.

[0033] The implementation principle of a rectangular pier column reinforcement cage binding frame in the embodiment of the present application is:

[0034] When in use, first adjust the column rack according to the size of the pier column reinforcement cage. When adjusting it, first adjust the distance between the two corresponding columns 4, so that the distance between the longitudinal hanging pieces 9 connected to the columns 4 can be adjusted to adjust the length of the pier column reinforcement cage. After adjustment, adjust the longitudinal hanging pieces 9 to adjust the width of the pier column reinforcement cage. After adjustment, adjust the verticality of the baffle 18 of the diagonal brace rack. When adjusting, turn the basket nut of the diagonal brace 19. Clockwise rotation can tighten the screw rods at both ends inward. By adjusting the length of the diagonal brace 19, the verticality of the baffle 18 is calibrated to ensure that the cross section of the manufactured reinforcement cage is flush.

[0035] After adjustment, the pier column steel bar 20 is inserted into the corresponding longitudinal hanging piece 9 and the slot 14 of the transverse hanging piece 13 in the shape of a "U" and placed. When placed, its end is in contact with the baffle 18. After the pier column steel bar 20 is placed, the main reinforcement of the steel cage is placed (such as Figure 5 As shown), after placement, the connected stirrups are fixed to the periphery of the pier column reinforcement 20 by tying or welding to realize the production of the pier column reinforcement cage;

[0036] After the production is completed, the fixing bolts 11 of the uppermost transverse hanging piece 13 of the steel bar positioning tooth plate are removed, and the fixing bolts 11 of the left and right longitudinal hanging pieces 9 are loosened (at this time, the crane lifts the steel cage upward by a certain distance to make the pier column steel bars 20 separate from the slots 14 of the hanging piece 9), and the longitudinal hanging piece 9 is pulled outward along the strip hole 10 to make the hanging plate 12 inside it separate from the pier column steel bars 20 of the steel cage, and then the two independent drainage trough hanging pieces 131 of the lower transverse hanging piece 13 are taken out, and finally the upper transverse hanging piece 13 is lifted off the tire frame together with the steel cage. After lifting, take out the upper horizontal hanging piece 13, so that the binding frame of the pier column steel bar cage can be accurately adjusted according to the different specifications and sizes. The main reinforcement spacing and stirrup spacing of the pier column steel bar cage are standard, and the steel bar cage is horizontal and vertical. Compared with traditional products, it is more standard, more standardized, and has a good overall effect. Moreover, the processed steel bar cage has high precision, and the steel bar cage skeleton is tied and transported to the site for overall lifting, which realizes the purpose of unified steel bar processing specifications, precise size, improved quality, significantly accelerated construction speed, high machinery utilization rate, and material saving.
