Description

Technical Field

[0001] This utility model relates to the field of rebar tying, and in particular to a rebar tying tool for precast box girders. Background Technology

[0002] Precast box girders are a common structural form in bridge engineering. They are usually made of materials such as concrete and steel bars. During the processing of precast box girders, steel bars need to be tied together. By using precast box girder steel bar tying jigs, the steel bars can be effectively positioned and fixed, which can ensure the overall structural strength and stability of the precast box girder.

[0003] The prior art patent document CN218340904U discloses a precast box girder rebar binding jig, comprising a jig body consisting of a base frame and two side frames. The side frames include an outer inclined column and an inner inclined column. Positioning holes are provided on the inner inclined columns, and clamps are fixed at the positioning holes. Positioning blocks are fixed on the clamp mounting ears, and U-shaped grooves are fixed on the positioning blocks. Movable and fixed clamps are provided within the U-shaped grooves, and a slide rail is provided in the U-shaped grooves. The bottom of the movable clamp is slidably connected to the slide rail. A threaded hole is provided in the U-shaped groove, and a screw passes through the threaded hole, with one end of the screw fixed to the movable clamp. This invention firmly fixes the transverse main reinforcement bars through the fixed and movable clamps. By moving the movable clamp, transverse main reinforcement bars of different diameters can be fixed, and the fixing position of the clamps can be adjusted to adapt to different binding spacing requirements, making it universally applicable.

[0004] Although the device has many beneficial effects, it still has the following problems: During use, the U-shaped grooves on both sides can only install steel bars in one direction, which is not convenient for binding steel bars that are spliced ​​together in the horizontal and vertical directions. The splicing of steel bars in different directions is not tight enough, which affects the binding effect. Secondly, the device is fixed by bolts and round holes during use, which is not convenient for precise adjustment of the position of steel bars during binding and is not convenient for meeting different needs. It needs to be improved. In view of this, we propose a precast box girder steel bar binding tool. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0017] Please see Figures 1 to 5 This utility model provides a tool for binding the reinforcing bars of precast box girders, and the technical solution is as follows: A precast box girder rebar tying tool includes a base plate 1. Multiple columns 2 are welded to the top of the base plate 1. First sliding sleeves 3 are slidably connected to the outer walls of each column 2. A crossbar 4 is welded to the top of two adjacent first sliding sleeves 3. Second sliding sleeves 5 are slidably connected to the outer walls of the crossbars 4. An installation assembly 6 is welded to the top of the side wall of the second sliding sleeve 5. The installation assembly 6 includes a connecting plate 601. An installation frame 602 is welded to one bottom end of the connecting plate 601. A spring 603 is welded to the top of the inner cavity of the installation frame 602. A sliding frame 604 is welded to the bottom of the spring 603. The sliding frame 604 is used to place transverse rebars. A positioning frame 605 is welded to the side wall of the first sliding sleeves 3. The positioning frame 605 is used to place longitudinal rebars. The spring 603 controls the downward movement of the sliding frame 604 to make the transverse steel bar abut against the longitudinal steel bar, which makes the precast box girder steel bar binding more secure. The side wall of the sliding frame 604 and the side wall of the positioning frame 605 are both threaded with screws 606. One end of the screw 606 is rotatably connected to the connecting block 607. The screw 606 is used to rotate and control the movement of the connecting block 607. The other side wall of the connecting block 607 is bonded with a clamping plate 608. The clamping plate 608 is used to move and clamp the steel bar to avoid displacement and facilitate binding. The other end of the screw 606 is welded with a first turner 609. The first turner 609 is used to facilitate the operator to turn it. The side wall of the first sliding sleeve 3 is threaded with an adjustment component 7.

[0018] It is worth noting that, in order to facilitate precise adjustment of the position of the first sliding sleeve 3, the adjustment component 7 specifically includes a bolt 701 threadedly connected to the side wall of the first sliding sleeve 3. A second lever 702 is welded to one end of the bolt 701. The second lever 702 is for the convenience of the operator to turn the bolt 701. A backing plate 703 is welded to the other end of the bolt 701. The backing plate 703 is for pressing against the side wall of the column 2. A magnetic plate 704 is adhered to the other side wall of the backing plate 703. A receiving groove 705 is opened in the inner cavity side wall of the first sliding sleeve 3. A positioning plate 706 is welded to the side wall of the column 2. The magnetic plate 704 is for adsorbing the positioning plate 706, which facilitates the improvement of the stability of the first sliding sleeve 3.

[0019] Next, in order to facilitate the movement of the sliding frame 604, a clearance groove 610 is provided at the bottom of the side wall of the mounting frame 602. The size and position of the clearance groove 610 match the size and position of the first handle 609. By using the clearance groove 610 that matches the size and position of the first handle 609, the first handle 609 is prevented from being obstructed when the sliding frame 604 moves.

[0020] Meanwhile, to facilitate use by staff, the outer circumference of the first turner 609 is integrally provided with multiple striped protrusions. The dimensions of the clamping plate 608 are matched with the dimensions of the inner cavity of the sliding frame 604 and the inner cavity of the positioning frame 605, respectively. The striped protrusions increase the friction, making it easier for staff to turn the first turner 609. The clamping plate 608, which is matched with the dimensions of the inner cavity of the sliding frame 604 and the inner cavity of the positioning frame 605, is used to limit the clamping plate 608 and prevent it from rotating with the screw 606.

[0021] Furthermore, to improve stability, specifically, the inner cavity of the first sliding sleeve 3 is matched with the size of the column 2, the inner cavity of the second sliding sleeve 5 is matched with the size of the crossbar 4, and the size of the abutment 703 is matched with the size of the receiving groove 705. The first sliding sleeve 3, which is matched with the size of the column 2, avoids loosening that could affect stability, and the receiving groove 705, which is matched with the size of the abutment 703, facilitates the movement of the abutment 703.

[0022] It is worth noting that, in order to facilitate the adsorption of the magnetic plate 704, specifically, the materials of the uprights 2 and crossbars 4 are 304 stainless steel, the material of the magnetic plate 704 is an AlNiCo magnet, and the material of the positioning plate 706 is 430 stainless steel. The uprights 2 and crossbars 4, made of 304 stainless steel, are non-magnetic, so as to avoid adsorption with the magnetic plate 704 and affect its use. The positioning plate 706, made of 430 stainless steel, is magnetic, so as to facilitate adsorption with the magnetic plate 704, and at the same time prevents rusting.

[0023] Finally, to facilitate the adjustment of the position of the reinforcing bars, specifically, the height of the second sliding sleeve 5 is greater than the height of the first sliding sleeve 3, and the side wall of the column 2 and the top of the crossbar 4 are sprayed with scale lines 8. By using the second sliding sleeve 5, which is greater than the height of the first sliding sleeve 3, it is easy to make the horizontally placed reinforcing bars fit together with the vertically placed reinforcing bars for binding. The scale lines 8 facilitate the precise adjustment of the position of the horizontal and vertical reinforcing bars.

[0024] Combination Figures 1-5 The specific usage process of the precast box girder reinforcement binding tool in this embodiment is as follows: 1: When this device is needed for binding the reinforcing bars of precast box girders, place the transverse reinforcing bars in the sliding frame 604 and the longitudinal reinforcing bars in the positioning frame 605. Turn the first lever 609 to rotate the screw 606, control the movement of the clamping plate 608 on one side of the connecting block 607 to clamp the reinforcing bars. The rebound force of the spring 603 controls the sliding frame 604 to move downward so that the transverse reinforcing bars press against the longitudinal reinforcing bars for binding. 2: Twist the second lever 702 to rotate the bolt 701, move the first sliding sleeve 3 precisely to the required position according to the scale line 8, and twist the second lever 702 in the opposite direction to rotate the bolt 701, causing the abutment plate 703 to press against the side wall of the column 2, and the magnetic plate 704 adsorbs the positioning plate 706 to complete the locking.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
