[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 2 - Figure 4 The utility model provides an embodiment: a highway bridge construction bracket that is easy to fix, including a pier 1, a bridge deck 2 is arranged on the top of the pier 1, a fixed block 2 4 is arranged on the left side of the pier 1, and a fixed block 1 3 is arranged on the right side of the pier 1. The front end of the fixed block 1 3 is fixedly connected with an extension block 1 5, and the front end of the fixed block 2 4 is fixedly connected with an extension block 2 8. A bidirectional screw 6 opposite to each other is threadedly connected between the rear sides of the extension block 1 5 and the extension block 2 8. The two extension blocks 1 5 and the bidirectional screw 6 are both arranged at the front end of the pier 1, and the rear sides of the fixed block 1 3 and the fixed block 2 4 are both fixedly connected with a clamping block 7. The two clamping blocks 7 are both against the rear side of the pier 1. The tops of the fixed block 1 3 and the fixed block 2 4 are both fixedly connected with a storage box 10, and the two storage boxes 10 are both provided with a stabilizing component. The left sides of the two bidirectional screws 6 are threadedly connected with nuts 23, and the two nuts 23 are arranged on the left side of the extension block 2 8. The front ends of the extension block 1 5 and the extension block 2 8 are both provided with thread grooves 22 opposite to each other.

[0033] Place the fixing block 1 3 and the fixing block 2 4 on both sides of the pier 1, and the two clamping blocks 7 are located behind the pier 1. Rotate the two bidirectional screws 6 to drive the extension block 1 5 and the extension block 2 8 to approach each other, and at the same time, make the fixing block 1 3 and the fixing block 2 4 approach each other and press against the two sides of the pier 1 for clamping. At the same time, the two clamping blocks 7 will also approach each other and press against the rear side of the pier 1 for clamping. Thread the two nuts 23 on the left sides of the two bidirectional screws 6 respectively and press against the left side of the extension block 2 8. After the fixing block 1 3 and the fixing block 2 4 clamp the pier 1, they are stabilized. When they need to be removed, rotate the two nuts 23 to the left to leave the two bidirectional screws 6, and then rotate the bidirectional screws 6 to make the fixing block 1 3 and the fixing block 2 4 move away from each other. At the same time, the two clamping blocks 7 will also move away from each other and no longer clamp the pier 1. At this time, pull the fixing block 1 3 and the fixing block 2 4 forward to leave the pier 1.

[0034] Reference Figure 1 and Figure 4 The stabilizing component includes a slide plate 11 and a spring 12. The slide plates 11 are arranged in plurality, and the springs 12 are arranged in plurality. One side of the plurality of springs 12 is respectively fixedly connected to the opposite side of the two slide plates 11, and the other side of the plurality of springs 12 is respectively fixedly connected to the inside of the two storage boxes 10. An expansion joint 9 is arranged between the pier 1 and the bridge deck 2. The two slide plates 11 are engaged on both sides of the expansion joint 9. The front and rear sides of the two slide plates 11 are both slidably connected with handles 13. The front and rear sides of the two storage boxes 10 are both provided with slide grooves 14, and the handles 13 are slidably connected inside the slide grooves 14.

[0035] Before operating the two bidirectional screws 6 to clamp the bridge pier 1 with the fixing block 1 3 and the fixing block 2 4, the slide plates 11 on both sides are ejected out of the storage box 10 through multiple springs 12 and engage the two sides of the expansion joint 9 to prevent the fixing block 1 3 and the fixing block 2 4 from falling when being clamped or released for removal. When it is necessary to remove them, hold the slide plate 11 and slide it into the slide groove 14, slide the handle 13 into the storage box 10 and squeeze the spring 12, and then take the fixing block 1 3 and the fixing block 2 4 forward.

[0036] Reference Figure 1 , Figure 5 and Figure 6 , a placement box 15 is fixedly connected to the opposite side of the fixed block 1 3 and the fixed block 2 4, and a push block 16 is slidably connected to the top of the two placement boxes 15. The two placement boxes 15 are respectively fixedly connected with uniformly distributed cylinders 17, and the output ends of multiple cylinders 17 are respectively fixedly connected to the bottom of the two push blocks 16. A drag plate 18 is slidably connected to the top of the push block 16, and a uniformly distributed shock absorber 19 is fixedly connected to the bottom of the drag plate 18. Multiple shock absorbers 19 are respectively fixedly connected to the bottom of the inner wall of the push block 16, and the tops of the two drag plates 18 are respectively provided with uniformly distributed anti-skid patterns 20, and the multiple anti-skid patterns 20 are against the bottom of the bridge deck 2. The bottoms of the opposite sides of the fixed block 1 3 and the fixed block 2 4 are respectively fixedly connected with uniformly distributed strengthening ribs 21, and the multiple strengthening ribs 21 are respectively fixedly connected to the bottom of the two placement boxes 15.

[0037] The push block 16 is pushed upward in the placement box 15 by multiple cylinders 17, so that the drag plate 18 is attached to the bottom of the bridge deck 2 for support. The friction force of the drag plate 18 against the bridge deck 2 is increased by multiple anti-skid grooves 20. The fixed block 1 3 and the fixed block 2 4 share part of the pressure borne by the placement box 15 by multiple reinforcing ribs 21. The larger pressure and impact force generated during the construction of the bridge deck 2 are buffered by the shock absorber 19 to improve the reinforcement effect. When the fixed block 1 3 and the fixed block 2 4 need to be taken out, the multiple cylinders 17 are contracted to make the push block 16 slide down to the placement box 15, and the drag plate 18 will also leave the bottom of the bridge deck 2 for easy removal.

[0038] Working principle: push the fixed block 1 3 and the fixed block 2 4 to both sides of the bridge pier 1, and the two clamping blocks 7 are located behind the bridge pier 1. The two bidirectional screws 6 drive the fixed block 1 3 and the fixed block 2 4 to approach each other and press against both sides of the bridge pier 1 for clamping. At the same time, the two clamping blocks 7 will also approach each other and press against the rear side of the bridge pier 1. Then, the two nuts 23 are respectively threaded into the two bidirectional screws 6 and press against the left side of the extension block 2 8 to stabilize the fixed block 1 3 and the fixed block 2 4 clamping the bridge pier 1. The push block 16 is pushed upward by multiple cylinders 17, so that the drag plate 18 is attached to the bottom of the bridge deck 2 through the anti-slip grooves 20 for support. During construction, the relatively large pressure and impact force generated are buffered and damped by the shock absorber 19, thereby improving the reinforcement effect of the bridge structure. When the fixing block 1 3 and the fixing block 2 4 need to be taken out, the multiple cylinders 17 are contracted to make the push block 16 slide down to the placement box 15 and drive the drag plate 18 to move down and leave the bottom of the bridge deck 2, and the two nuts 23 are rotated to the left to leave the two bidirectional screw rods 6 respectively, and then the bidirectional screw rods 6 are rotated to make the fixing block 1 3 and the fixing block 2 4 move away from each other, thereby releasing the clamping of the bridge pier 1, and at the same time, the two clamping blocks 7 will also move away from each other, and at this time, the fixing block 1 3 and the fixing block 2 4 are pulled forward to leave the bridge pier 1, and the removal is completed.
