[0006] In order to achieve the above object, the utility model provides the following technical scheme: box beam steel bar binding positioning frame with damper, including bottom beam, the top of bottom beam is fixedly installed with the support column of two numbers, the top of bottom beam is fixedly installed with the inclined support column of two numbers, the top of inclined support column is connected with one side of support column, one side of support column is provided with the damper of four numbers, the inside of damper is slidably installed with longitudinal positioning frame,
[0007] The damper includes a base fixedly installed on one side of the support column by bolts, a steel pipe fixedly installed on one side of the base, a damping inner bag fixedly installed in the steel pipe, and four mounting holes formed in one side of the base.
[0008] Further, two of the four dampers form a group, and a longitudinal positioning frame is slidably installed in the group of dampers.
[0009] Further, the longitudinal positioning frame includes two damping positioning rods slidably installed in the two groups of dampers, a pull rod fixedly installed at one end of the two damping positioning rods, a vertical rod fixedly installed between the two damping positioning rods, and a driven positioning rod fixedly installed on one side of the vertical rod.
[0010] Further, a hinge is fixedly installed at the top of the support column, and a rotating L-shaped steel is fixedly installed on the movable part of the hinge.
[0011] Further, one side of the rotating L-shaped steel is in contact with one side of the inclined support column, and a plurality of equally spaced inclined side positioning grooves are fixedly formed on the side of the rotating L-shaped steel perpendicular to the inclined support column.
[0012] Further, two bottom L-shaped steels are fixedly installed at the top of the bottom beam, and one side of each of the two bottom L-shaped steels away from each other is in contact with one side of the two inclined support columns opposite to each other.
[0013] Further, a plurality of equally spaced bottom positioning grooves are formed on the side of the bottom L-shaped steel perpendicular to the bottom beam.
[0014] Compared with the prior art, the box beam steel bar binding positioning frame with damper has the following beneficial effects:
[0015] 1. This damped box girder rebar tying positioning frame uses a damper installed on one side of the support column. The damping positioning rod of the longitudinal positioning frame passes through the damper, and the damping positioning rod contacts the damping inner liner in the damper. This creates friction between the damping positioning rod and the damper, preventing the longitudinal positioning frame from easily moving during rebar tying. This solves the problem of common box girder rebar tying positioning frames where the positioning rod is usually inserted into a steel pipe welded to one side of the support column. The positioning rod is inserted during tying and pulled out afterward. However, due to the looseness between the steel pipe and the positioning rod, the positioning rod easily moves during rebar tying, requiring repeated adjustments to its position.
[0016] 2. The box girder reinforcement binding and positioning frame with damper is constructed by hinged rotating L-shaped steel to the top of the support column. During reinforcement binding, one side of the rotating L-shaped steel is rotated to contact the diagonal support column, and the reinforcement is positioned by the diagonal positioning groove. After binding is completed, the rotating L-shaped steel is rotated upward to facilitate the lifting of the entire reinforcement cage from above. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1: Please refer to Figures 1-4The box girder reinforcement binding and positioning frame with dampers includes a bottom beam 1, two support columns 2 are fixedly installed on the top of the bottom beam 1, two diagonal bracing columns 3 are fixedly installed on the top of the bottom beam 1, the top of the diagonal bracing column 3 is fixedly connected to one side of the support column 2, four dampers 4 are provided on one side of the support column 2, and a longitudinal positioning frame 5 is slidably installed inside the damper 4.
[0024] The damper 4 includes a base 41 bolted to one side of the support column 2. A steel pipe 42 is fixedly installed on one side of the base 41, and a damping liner 43 is fixedly installed inside the steel pipe 42. Four mounting holes 44 are provided on one side of the base 41. The damping liner 43 has a certain degree of elasticity, which allows the surface of the rod passing through it to fully contact the inner surface of the damping liner 43, forming a large frictional force, making it difficult for the longitudinal positioning frame 5 to move.
[0025] Meanwhile, the four dampers 4 are arranged in pairs, and a longitudinal positioning frame 5 is slidably installed inside each pair of dampers 4.
[0026] The longitudinal positioning frame 5 includes two damping positioning rods 51 slidably installed inside two sets of dampers 4. A pull rod 52 is fixedly installed at one end of each damping positioning rod 51, and a vertical rod 53 is fixedly installed between the two damping positioning rods 51. A driven positioning rod 54 is fixedly installed on one side of the vertical rod 53. The friction between the damping positioning rods 51 and the dampers 4 prevents the longitudinal positioning frame 5 from easily moving. When movement is required, the position of the damping positioning rods 51 and the driven positioning rod 54 is adjusted by the operator applying a pulling or pushing force greater than the friction force to the pull rods 52.
[0027] Meanwhile, two bottom L-shaped steel beams 8 are fixedly installed on the top of the bottom beam 1, and the side of the two bottom L-shaped steel beams 8 that is far away from each other is in contact with the side of the two diagonal bracing columns 3 that are opposite to each other.
[0028] The bottom L-shaped steel 8 has several equally spaced bottom positioning grooves 81 on one side perpendicular to the bottom beam 1. The bottom positioning grooves 81 on one side of the bottom L-shaped steel 8 are used to position the bottom reinforcing bars, thereby improving the efficiency of reinforcing bar binding.
[0029] Example 2: Based on Example 1, a hinge 6 is fixedly installed on the top of the support column 2, and a rotating L-shaped steel 7 is fixedly installed on the movable part of the hinge 6.
[0030] One side of the rotating L-shaped steel 7 contacts one side of the diagonal bracing column 3. Several equally spaced inclined positioning grooves 71 are fixedly opened on the side of the rotating L-shaped steel 7 perpendicular to the diagonal bracing column 3. The inclined positioning grooves 71 are used to position the inclined reinforcing bars, improving the efficiency of reinforcing bar binding. After the entire reinforcing bar binding is completed, the rotating L-shaped steel 7 is rotated upward to the top of the support column 2, making it convenient to lift the entire reinforcing bar structure out from above.
[0031] In this embodiment, when the pull rod 52 is pushed, the damping positioning rod 51 and the driven positioning rod 54 are moved between the two diagonal support columns 3, which facilitates the positioning of the longitudinal steel bars. Under the action of the damper 4, the damping positioning rod 51 needs to be moved with a force greater than the friction force, so the damping positioning rod 51 is not easy to move, which increases the stability of the longitudinal positioning frame 5 and prevents the longitudinal positioning frame 5 from moving accidentally.
