DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0023] The reinforcement binding frame of the prefabricated bridge pier column in this embodiment includes a bottom support frame 1, which is used to support the entire frame. The bottom support frame 1 in this embodiment is a rectangular frame support frame as a whole, and includes a plurality of vertically staggered horizontal plates 2 and longitudinal plates. The longitudinal plates mentioned here refer to plates parallel to the main reinforcements of the binding, and the horizontal plates 2 are perpendicular to the main reinforcements. The length direction of the horizontal plates 2 in this embodiment is the left and right direction of the bottom support frame 1. A horizontal plate 2 is arranged at a certain interval, and a C-shaped slide 3 is arranged on the horizontal plate 2 along the length direction of the horizontal plate 2. The C-shaped slide 3 penetrates the horizontal plate 2, and the inverted T-shaped transverse positioning plate 4 is slidably connected in the C-shaped slide 3. The inverted T-shaped transverse positioning plate 4 can slide left and right in the C-shaped slide 3, and the inverted T-shaped transverse positioning plate 4 can slide out of the C-shaped slide 3 to realize the replacement of the inverted T-shaped transverse positioning plate 4. A plurality of fixing holes A7 are arranged on both sides of the C-shaped slide 3, and the fixing holes A7 penetrate the horizontal plate 2 upward, and the inverted T-shaped transverse positioning plate 4 is fixed to the C-shaped slide 3 by bolts passing through the fixing holes A7. A plurality of arc grooves A5 are evenly arranged on the upper surface of the inverted T-shaped transverse positioning plate 4. The spacing of the arc grooves A5 is made according to the design requirements. The arc grooves A5 are used to place the main reinforcement bars. The arc grooves A5 can locate the position and spacing of the bottom main reinforcement bars.

[0024] Two vertical plates 8 are slidably connected on the inverted T-shaped transverse positioning plate 4. A lower slot 9 is provided at the bottom of each vertical plate 8. The lower slot 9 is an inverted U-shaped slot that opens downward. The lower slot 9 is just slidably connected to the inverted T-shaped transverse positioning plate 4, so that the vertical plate 8 can slide along the inverted T-shaped transverse positioning plate 4, thereby adjusting the position of the vertical plate 8. Fixing holes B10 are provided on both sides of the bottom of the vertical plate 8. The side of the inverted T-shaped transverse positioning plate 4 is evenly provided with a number of adjustment holes A6 along the length direction of the inverted T-shaped transverse positioning plate 4. The fixing holes B10 match the adjustment holes A6. The vertical plate 8 is fixed to the inverted T-shaped transverse positioning plate 4 by bolts passing through the fixing holes B10 and the adjustment holes A6, so that the vertical plate 8 no longer slides along the inverted T-shaped transverse positioning plate 4, and the fixed position of the vertical plate 8 can be adjusted according to the adjustment holes A6 aligned with the fixing holes B10, thereby changing the positions of the vertical plates 8 on the left and right sides and the distance between them, thereby changing the size of the tied steel bar skeleton, and the size of the steel bar skeleton can be adjusted according to different prefabricated pier column sizes.

[0025] A U-shaped groove 11 is provided above the lower slot 9 of the vertical plate 8. The U-shaped groove 11 penetrates the vertical plate 8 upwards. The U-shaped groove 11 penetrates the left and right sides and the upper surface of the vertical plate 8, so that the upper end of the vertical plate 8 is open. A plurality of hydraulic cylinders 12 are installed on the bottom surface of the U-shaped groove 11. The upper end of the hydraulic rod of the hydraulic cylinder 12 is fixed with a horizontal plate 13. The length of the horizontal plate 13 is equal to the length of the vertical plate 8. The width of the horizontal plate 13 is equal to the width of the U-shaped groove 11. The length mentioned here refers to the length along the length direction of the horizontal plate 2. The horizontal plate 13 can slide up and down in the U-shaped groove 11. A vertical positioning plate 14 is placed above the horizontal plate 13. The width of the vertical positioning plate 14 is also equal to the width of the U-shaped groove 11, but the length of the vertical positioning plate 14 is less than the length of the vertical plate 8. Preferably, the length of the vertical positioning plate 14 is equal to half the length of the vertical plate 8. A plurality of adjustment holes B15 are evenly arranged from top to bottom on the side of the vertical plate 8, and a fixing hole C16 matching the adjustment hole B15 is arranged from top to bottom on the vertical positioning plate 14. The vertical positioning plate 14 is fixed to the vertical plate 8 by a screw passing through the adjustment hole B15 and the fixing hole C16, and the two ends of the screw are fixed by nuts. A plurality of short positioning columns 17 are evenly arranged from top to bottom on the side of the vertical positioning plate 14, and an arc groove B18 is arranged on the upper surface of the short positioning column 17. The spacing between the upper and lower arc grooves B18 is made according to the design requirements of the main reinforcement spacing, and the arc groove B18 is used to locate the position and spacing of the left and right main reinforcement bars.

[0026] A plurality of through holes 22 are provided on the upper part of the vertical positioning plate 14. The through holes 22 are along the length direction of the vertical positioning plate 14 and penetrate the vertical positioning plate 14. A long positioning column 23 passes through the through holes 22 between the vertical positioning plates 14 on the left and right sides. A plurality of arc grooves C24 are evenly provided on the upper surface of the long positioning column 23. Similarly, the spacing of the arc grooves C24 is made according to the main reinforcement spacing design requirements. The arc grooves C24 are used to locate the position and spacing of the upper steel main reinforcement. In order to make the long positioning column 23 more stable, it is preferred that both ends of the long positioning column 23 are threaded sections, and the two ends of the long positioning column 23 can be fastened together with the vertical positioning plate 14 by nuts. Because the force of the steel main reinforcement is downward, the long positioning column 23 will not move normally, and can be used normally without the reinforcement of the threaded section and the nut.

[0027] The inverted T-shaped transverse positioning plates 4, vertical positioning plates 14 and long positioning columns 23 made by the present invention can all be replaced, so multiple groups of different inverted T-shaped transverse positioning plates 4, vertical positioning plates 14 and long positioning columns 23 can be processed and made, and different groups of inverted T-shaped transverse positioning plates 4, vertical positioning plates 14 and long positioning columns 23 have different steel bar control spacings, so that steel bar skeletons with different requirements and spacings can be made. Specifically, the inverted T-shaped transverse positioning plates 4 include multiple groups, and the arc grooves A5 of the inverted T-shaped transverse positioning plates 4 of different groups are different in spacing; the vertical positioning plates 14 include multiple groups, and the upper and lower positioning columns A of the vertical positioning plates 14 of different groups are different in spacing; the long positioning columns 23 include multiple groups, and the arc grooves C24 of the long positioning columns 23 of different groups are different in spacing, so that the appropriate inverted T-shaped transverse positioning plates 4, vertical positioning plates 14 and long positioning columns 23 can be selected according to needs for steel bar binding.

[0028] To facilitate replacement of the inverted T-shaped transverse positioning plate 4 and the vertical positioning plate 14 , preferably, a handle A19 is fixed outwardly on the outer side of the inverted T-shaped transverse positioning plate 4 , and a handle B20 is fixed outwardly on the outer side of the vertical positioning plate 14 .

[0029] To further enhance the stability of the entire device, preferably, an oblique support rod 21 is connected to the vertical plate 8, and the lower part of the oblique support rod 21 is fixed to the inverted T-shaped horizontal positioning plate 4 by a bolt passing through the adjustment hole A6. The upper end of the oblique support rod 21 can be fixed on the vertical plate 8, and a screw hole is provided at the lower part of the oblique support, and the horizontal spacing between this screw hole and the fixing hole B10 is several times the spacing between adjacent adjustment holes A6 on the inverted T-shaped horizontal positioning plate 4, that is, when the fixing hole B10 is aligned with a certain adjustment hole A6, the screw hole is also aligned with another adjustment hole A6, so that there is no need to drill additional holes, and the lower part of the oblique support rod 21 can be directly fixed to the inverted T-shaped horizontal positioning plate 4 with bolts.

[0030] When the device of the present invention is used, firstly, according to the requirements of the spacing between the main reinforcement bars, the appropriate inverted T-shaped transverse positioning plate 4, the vertical positioning plate 14 and the long positioning column 23 are selected, and then the inverted T-shaped transverse positioning plate 4 is first slid into the C-shaped slide groove 3, and the bolts are tightened into the fixing holes A7 to fix the inverted T-shaped transverse positioning plate 4, and then the lower slots 9 of the two vertical plates 8 are clamped on the inverted T-shaped transverse positioning plate 4, and according to the size of the prefabricated pier column, the vertical plate 8 is slid on the inverted T-shaped transverse positioning plate 4, and the spacing and position of the vertical plates 8 on both sides are adjusted, and the fixing holes B10 on the sides of the vertical plates 8 are aligned with the adjustment holes A6. After the adjustment, Use bolts passing through the fixing holes B10 and the adjusting holes A6 to fix the vertical plate 8 to the inverted T-shaped transverse positioning plate 4, and then fix the lower part of the oblique support rod 21 to the inverted T-shaped transverse positioning plate 4, and then place the vertical positioning plate 14 on the horizontal plate 13, and according to the size of the prefabricated pier, let the hydraulic cylinder 12 work to make the vertical positioning plate 14 rise or fall to a suitable position, and then the screw rod passes through the adjusting hole B15 on the vertical plate 8 and the fixing hole C16 on the vertical positioning plate 14, and tighten the nuts at both ends of the screw rod to fix the vertical positioning plate 14 to the vertical plate 8. The long positioning column 23 is passed through the through hole 22 at the upper part of 14, and the nuts at both ends of the long positioning column 23 are tightened to fix the long positioning column 23 and the vertical positioning plate 14 together. After the tire frame is assembled, the main reinforcement can be placed on the arc groove A5, the arc groove B18, and the arc groove C24, and the stirrups can be tied to tie the steel skeleton of the prefabricated pier column. When the steel skeleton of the prefabricated pier column is tied on the tire frame, the screw for fixing the vertical positioning plate 14 is removed, and then the hydraulic cylinder 12 is controlled to move the vertical positioning plate 14 down a small distance along the U-shaped groove 11, and the vertical positioning plate 14 drives the short positioning column 17 and The long positioning column 23 moves downward a very small distance, allowing the short positioning column 17 and the long positioning column 23 to separate from the main reinforcement and be located in the gap of the reinforcement skeleton. At this time, the nuts at both ends of the long positioning column 23 can be unscrewed, and the long positioning column 23 can be pulled out from the gap of the reinforcement skeleton and the vertical positioning plate 14. The long positioning column 23 is removed, and then the handle B20 is pulled outward. The vertical positioning plate 14 slides outward on the horizontal plate 13, driving the short positioning column 17 to be pulled out from the gap of the reinforcement skeleton, so that the short positioning column 17 is separated from the reinforcement skeleton. At this time, the tied reinforcement skeleton can be lifted from the tire frame to the required position.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
