Bridges are made of a variety of materials, including but not limited to steel, concrete, wood and stone.

[0003] For the binding of guardrail steel bars in the existing bridge anti-collision deformation joint construction, the steel bars are bound manually according to the drawings. However, manual binding is prone to uneven binding, which in turn affects the quality and bearing capacity of the steel bar binding, easily leads to local stress concentration, reduces the tensile and bending resistance of the bridge, thus affecting the construction quality and posing potential safety hazards.

[0004] Therefore, it is necessary to design a guardrail steel bar binding positioning and adjusting device for bridge anti-collision deformation joint construction that can adjust and position the spacing between steel bars, make the steel bars more neatly arranged, improve the binding quality, improve the construction quality and reduce potential safety hazards.

Adjacent bevel gears mesh with each other.

[0009] As an improvement to the above solution, handles are provided on the cranks.

[0010] As an improvement to the above solution, it further includes a guide frame and a connecting frame. Guide frames are connected to the outsides of the first measuring plate and the second measuring plate, and connecting frames are slidably connected to the guide frames.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further describes the present utility model in detail in conjunction with the drawings and specific embodiments, but does not limit the protection scope and application scope of the present utility model.

[0018] A device for binding and positioning adjustment of guardrail steel bars in the construction of bridge anti-collision deformation joints, as shown in Figure 1 and Figure 2As shown in the figure, it includes a base 1, a scale plate 2, a bidirectional lead screw 3, a crank 4, a first measuring plate 5, a unidirectional lead screw 6, a second measuring plate 7, bevel gears 8, a guide frame 9, a connecting frame 10, a clamping plate 11 and a spring 12. On the upper side of the front part of the base 1, a scale plate 2 is connected. The bidirectional lead screw 3 is rotatably connected to the base 1. The right side of the bidirectional lead screw 3 is connected with a crank 4. Both the left and right parts of the bidirectional lead screw 3 are threadedly connected with a first measuring plate 5. The first measuring plates 5 are all slidably connected to the base 1. The inner sides of the first measuring plates 5 are also connected with a scale plate 2 for easy positioning. The upper parts of the first measuring plates 5 are also rotatably connected with a crank 4. Handles are provided on the cranks 4 for easy hand-held rotation of the crank 4. The front parts of the first measuring plates 5 are all rotatably connected with a unidirectional lead screw 6. The second measuring plates 7 are all threadedly connected to the unidirectional lead screws 6. The second measuring plates 7 are all slidably connected to the adjacent first measuring plate 5. Bevel gears 8 are connected to the rear parts of the cranks 4 on the first measuring plates 5. Bevel gears 8 are also connected to the upper parts of the unidirectional lead screws 6. Two adjacent bevel gears 8 are meshed with each other. Guide frames 9 are connected to the outer sides of the first measuring plates 5 and the second measuring plates 7. Connecting frames 10 are slidably connected to the guide frames 9. Two clamping plates 11 are slidably connected to the upper connecting frames 10.

[0019] When the construction of the bridge anti-collision deformation joint requires tying of guardrail steel bars, this device can be used. Take this device to the place where the bridge anti-collision deformation joint is constructed. Clamp the steel bar between the clamping plate 11 and the connecting frame 10. After the spring 12 is stretched and then rebounds, the steel bar is fixed. Then, turn the crank 4 through the handle, drive the bevel gear 8 to rotate. The bevel gears 8 engage with each other and move, causing the unidirectional lead screw 6 to rotate. Under the action of the thread, the second measuring plate 7 moves downward, driving the upper connecting frame 10 and the clamping plate 11 to move, causing the steel bar to move. Then, by observing the scale plate 2, adjust the vertical distance between the steel bars. After adjusting to the appropriate height, turn the bidirectional lead screw 3 by hand through the crank 4. Under the action of the thread, the first measuring plates 5 move inward simultaneously, driving the unidirectional lead screw 6, the second measuring plate 7, the bevel gear 8, the guide frame 9, the connecting frame 10 and the clamping plate 11 to move. Then, by observing the scale plate 2, adjust the horizontal distance between the steel bars, so that the distance between the steel bars can be adjusted and positioned, making the arrangement of the steel bars more neat, improving the tying quality, improving the construction quality, reducing potential safety hazards. After adjusting to the appropriate distance, pull the connecting frame 10 along the guide frame 9 backward by hand, and then remove the steel bar, and then carry out tying, so that the steel bar can be removed, facilitating the tying of the steel bar and improving the convenience of using this device. After tying is completed, just remove the steel bar.
