[0002] The cross-section of steel bars used in the construction engineering field is generally round, mainly including plain round steel bars, ribbed steel bars and twisted steel bars. Steel bars will break during their service. The generally economical and feasible measure is to re-weld the broken steel bars to extend the service life of reinforced concrete.

[0003] During the welding process of steel bars, the two ends of the broken steel bars need to be strictly aligned. However, the traditional steel bar welding positioning device cannot ensure that the broken steel bars are concentric and coaxial, which leads to cracks inside the re-welded steel bars.

[0034] Embodiment 3

[0035] like Figure 1-2 As shown, on the basis of the above-mentioned embodiment 2, the positioning and discharging mechanism 8 includes a sliding rod 801 slidably connected to the sliding hole, one end of the sliding rod 801 is fixedly connected to a reset plate 804, the other end of the sliding rod 801 is fixedly connected to a force plate 802, and the left side of the reset plate 804 is fixedly connected to a reset spring 803. By setting the reset spring 803, the reset plate 804 is driven to reset, and by setting the force plate 802, the force plate 802 is pulled outward, and the movement of the force plate 802 drives the sliding rod 801 to slide, thereby compressing the length of the reset spring 803;

[0037] Embodiment 4

[0038] like Figure 1-2As shown, on the basis of the above-mentioned third embodiment, the upper surface of the mounting plate 812 is rotatably connected with a rotating shaft 813, and the surface of the rotating shaft 813 is rotatably connected with the left placement plate 809. By setting the mounting plate 812, the movement of the reset plate 804 drives the mounting plate 812 to move, so that the left placement plate 809 and the right placement plate 810 connected to the mounting plate 812 are separated, and the lower surface of the left placement plate 809 is fixedly connected to the upper surface of the mounting plate 812, and the top of the rotating shaft 813 is fixedly connected with a screw rod 807, and the top of the screw rod 807 is fixedly connected with a handle 805. The plate 806 is threadedly connected to the surface of the screw rod 807, and the front of the pressing plate 806 is slidably connected to the back of the guide slide 808. By setting the handle 805, the screw rod 807 is rotated to rotate the handle 805, and at the same time, under the limiting effect of the guide slide 808, the pressing plate 806 is driven to move upward or downward, so that the pressing plate 806 and the left placement plate 809 are close to or away from each other; by setting the left placement plate 809 and the pressing plate 806 to be close to each other, the steel bars placed on the inner bottom wall of the left placement plate 809 and the right placement plate 810 are clamped and fixed to prevent shaking during welding;

[0039] Embodiment 5

[0040] like Figure 1-2 As shown, on the basis of the above-mentioned fourth embodiment, a fixed support plate 811 is provided at one end of the mounting plate 812 away from the force-bearing plate 802. By providing the fixed support plate 811, fixed support for the right placement plate 810 is achieved. One end of the fixed support plate 811 is fixedly connected to the left side of the right support frame 2. The position of the fixed support plate 811 corresponds to that of the mounting plate 812. The upper surface of the fixed support plate 811 is fixedly connected to the right placement plate 810. A buffer and anti-collision mechanism is provided at the bottom of the pressing plate 806.

[0041] By setting the above technical scheme, during specific use: in the initial state, the pressing plate 806 and the left placing plate 809 are far away from each other. When the steel bar positioning device for construction is used, the user first manually rolls the heavier broken steel bar through the inclined surface of the loading plate 5 to the upper surface of the loading plate 5, and pushes the steel bars at both ends respectively, so that the steel bars slide to the inner bottom wall positions of the front and rear left placing plates 809 and the right placing plates 810 respectively. Since the front and rear left placing plates 809 and the right placing plates 810 are exactly the same in shape, size and height, the two ends of the fracture are concentric and coaxial. Then, the handle 805 is rotated, and the rotation of the handle 805 drives the screw rod 807 to rotate, so that the pressing plate 806 descends and moves toward the left placing plate 809. During the movement, the inner top wall of the pressing plate 806 contacts the surface of the broken steel bar. , press the steel bar downward to fix it, so that the steel bar that was originally placed on the left placement plate 809 and was tilted upward is gradually kept level with the horizontal plane. In this process, the distance between the steel bars at both ends is gradually adjusted to make them close to each other and fit together to ensure the accuracy of welding. After welding the broken steel bars, drag the force plate 802 outward, and the movement of the force plate 802 drives the sliding rod 801 to slide, thereby compressing the length of the reset spring 803. At this time, the mounting plate 812 is away from the fixed support plate 811, so that the left placement plate 809 and the right placement plate 810 on the mounting plate 812 are separated, and the processed steel falls off from the separation point. The avoidance hole 7 prevents interference at this time, which is convenient for taking out the welded steel bars. With the above structure, the welded steel bars are in a concentric and coaxial state, which ensures the strength after welding and prevents shaking during welding.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
