[0030] Embodiment

[0031] The following is further illustrated with specific embodiments. Referring to Figures 1 - 5 As shown, the present utility model is a positioning structure of a clamping tool for pre-buried steel bars of a T-beam anti-collision guardrail, including a fixed plate 2. The fixed plate 2 is in a certain direction. The fixed plate 2 is fixed to the steel box girder formwork 1 through bolts 21. A plurality of preset holes can be opened along the length direction at the top edge of the steel box girder formwork 1. The size of the preset holes is the same as the diameter of the bolts 21 to facilitate the fixation of the fixed plate 2 at different positions. A vertical rod 3 is welded on the fixed plate 2, and the cross-section of the vertical rod 3 is square; the cross bar 4 is installed on the vertical rod 3 through a positioning seat 5. A limit groove 41 is opened along the length direction of the cross bar 4. The width of the limit groove 41 is not less than the diameter of the steel bar. One end of the limit groove 41 away from the vertical rod 3 is open. A guide fillet 411 is provided at the open end of the limit groove 41 of the cross bar 4, and the guide fillet 411 can facilitate the entry of the steel bar;

[0032] The positioning seat 5 is slidably connected to the cross bar 4. An arc-shaped positioning opening 51 for the steel bar to be inserted is provided on the opening side of the positioning seat 5 facing the limiting groove 41. A notch groove 52 is also penetrated through the top wall of the positioning seat 5. A pair of turning plates 6 are hingedly arranged at the position of the notch groove 52 of the positioning seat 5. A clamping opening 61 is provided on each of the pair of turning plates 6. The clamping opening 61 is semicircular. The clamping openings 61 of the pair of turning plates 6 together form a space for the steel bar to be inserted. At the same time, the two turning plates 6 and the positioning seat 5 together enclose a ring and are sleeved on the cross bar 4. The direction of the hinge axis of the two turning plates 6 is consistent with the length direction of the cross bar 4. The hinge axis of the two turning plates 6 is close to the intersection position of the top wall of the positioning seat 5 and the turning plate 6 to facilitate the rotation of the turning plate 6;

[0033] Referring to Figure 2 and Figure 3 , a sliding seat 31 is slidably sleeved on the vertical rod 3. A screw rod 311 is threadedly connected to the sliding seat 31. The screw rod 311 is used to abut against the vertical rod 3, thereby fixing the position of the sliding seat 31 on the vertical rod 3 to facilitate the adjustment of the height of the cross bar 4. Among them, the screw rod 311 is a butterfly screw rod 311 to facilitate the staff to turn. The sliding seat 31 is provided with a sliding groove 312 along the length direction. The cross section of the sliding groove 312 is square. The cross bar 4 is slidably connected to the sliding groove 312. An adjusting member 32 for adjusting the cross bar 4 to slide along the length direction of the sliding groove 312 and be fixed to the position after sliding is provided on the sliding seat 31. The adjusting member 32 is a lead screw 321 and a handle 322. The lead screw 321 is rotatably connected in the sliding seat 31 along the length direction of the sliding groove 312. The lead screw 321 is threadedly penetrated through the cross bar 4. The handle 322 is welded to the lead screw 321. Turning the handle 322 can rotate the lead screw, thereby driving the cross bar 4 to move. After stopping turning the handle 322, the position of the cross bar 4 will be fixed.

[0034] Referring to Figure 3 and Figure 5 , in order to facilitate fixing the position of the positioning seat 5 after the positioning seat 5 slides along the cross bar 4, the positioning member 7 includes a pin 71. The pin 71 is welded on each of the pair of turning plates 6. A plurality of slots 42 are provided on the top wall of the cross bar 4 along the length direction. The pin 71 and the slot 42 are inserted and matched with each other. The bottom of the pin 71 is in a sharp cone shape to facilitate the pin 71 to be guided into the slot 42 after the turning plate 6 rotates.

[0035] Referring to Figure 3 and Figure 4, To further locate the position of the steel bars, the reinforcement member 8 includes a sliding rod 81, a bottom block 82, and a clamping block 83. The positioning seat 5 is vertically provided with a through hole 53. The sliding rod 81 is vertically slidably inserted through the through hole 53 of the positioning seat 5. The sliding rod 81 is square-shaped to prevent the sliding rod 81 from rotating. The bottom block 82 is welded to the bottom of the sliding rod 81. The bottom block 82 is also provided with an arc-shaped positioning opening 51. The arc-shaped positioning opening 51 on the bottom block 82 is directly below the arc-shaped positioning opening 51 of the positioning seat 5. The clamping block 83 is also provided with an arc-shaped positioning opening 51 that is aligned with the arc-shaped positioning opening 51 on the bottom block 82. A pair of sliding blocks 831 are welded to the clamping block 83. The bottom block 82 is vertically provided with a pair of clamping grooves 821. The cross-section of the clamping groove 821 is in the shape of a 'T' or a dovetail. The top end of the clamping groove 821 is through, and the bottom end of the clamping groove 821 is closed. After the sliding block 831 is slidably clamped in the clamping groove 821, the steel bar will be clamped into the arc-shaped positioning openings 51 of the clamping block 83 and the bottom block 82, realizing the positioning of the steel bar.

[0036] Referring to Figure 3 and Figure 4 , a rubber sleeve 531 is coaxially fixedly bonded in the through hole 53 of the positioning seat 5. The sliding rod 81 is slidably inserted through the rubber sleeve 531. The inner wall of the rubber sleeve 531 abuts against the outer wall of the sliding rod 81. The rubber sleeve 531 will play a damping role to prevent the sliding rod 81 from automatically falling and affecting the fixing of the steel bar. A handle 84 is welded to the top wall of the sliding rod 81 for the convenience of the staff to operate. The inner side walls of the arc-shaped positioning openings 51 of the sliding block 831 and the bottom block 82 are both covered with a polytetrafluoroethylene layer 85. When pouring concrete, as the concrete rises in the steel box girder formwork 1, due to the lubricity of the polytetrafluoroethylene layer 85, it is convenient for the staff to pull up the sliding rod 81, the bottom block 82, the clamping block 83, etc. as a whole. During this process, the steel bar can also be kept limited all the time.

[0037] The working process is as follows: First, according to the position of the embedded steel bar, the fixing plate 2 is fixedly installed near the embedded steel bar on the steel box girder formwork 1 using bolts 21. The height of the cross bar 4 is adjusted using the screw rod 311 and the position of the cross bar 4 in the horizontal direction is adjusted using the lead screw 321. Finally, the embedded steel bar is clamped in the limit groove 41 of the cross bar 4. Then, the arc-shaped positioning opening 51 of the positioning seat 5 is used to limit the steel bar, and a pair of turning plates 6 are rotated to clamp the steel bar with the clamping opening 61 of the turning plates 6, thereby fixing the position of the embedded steel bar and realizing the positioning of the steel bar. The arc-shaped positioning openings 51 of the bottom block 82 and the clamping block 83 can clamp the steel bar at the same time, realizing the fixation of different positions and heights of the steel bar, further playing a role in preventing the steel bar from shifting. After the embedded steel bar is accurately positioned, during the concrete pouring process, the steel bar is prevented from shifting, thereby reducing the workload of later adjustment and maintenance, while reducing the construction cost and facilitating the installation of the later guardrail.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
