[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Rebar is an important building material for construction. Especially when building high-rise buildings, it is necessary to weld multiple short steel bars at both ends to form long steel bars, and then overlap the long steel bars on the outer frame of the concrete to enhance the strength of the concrete.

[0003] In the prior art, such as the "A construction steel bar welding clamping device" with patent publication number CN220427382U, which includes a support plate, a workbench and a transmission assembly, the workbench is arranged at the upper end of the support plate, the transmission assembly is arranged inside the workbench, and the transmission assembly includes a transmission bin, which is opened inside the workbench.

[0004] However, in the prior art, the steel bar is a cylindrical structure with an outer wall that is basically arc-shaped. When the two ends are butt-jointed, it is necessary not only to ensure that the two steel bars are clamped together, but also to ensure that the force applied during clamping does not act on the steel bars, causing the sides of the two steel bars to slip and cause the butt joint to shift. The existing steel bar welding clamping device is difficult to ensure the positioning of the steel bar under the action of a large clamping force, which can easily lead to the problem of displacement of the steel bar during welding. Utility Model Content

[0005] The utility model aims to solve the problem that the steel bar welding clamping device existing in the prior art is difficult to ensure the positioning of the steel bar under the action of a large clamping force, which easily leads to displacement of the steel bar during welding, and proposes a steel bar welding clamping device for construction.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a steel bar welding clamping device for construction, comprising two lifting platforms, the surfaces of the two lifting platforms are slidably connected with a lower clamping plate and an upper clamping plate, when the steel bars are welded, a part of the welded ends of the two steel bars overlap, so that more solder can be applied to the gap between the two steel bars, so two groups of lifting platforms are set, the outer side walls of the lower clamping plate on one side of the lifting platform and the upper clamping plate on the other side are fixedly connected with a telescopic cylinder, the inner side wall of the telescopic cylinder is slidably connected with a telescopic column, the telescopic column and the bottom wall of the telescopic cylinder are fixedly connected with a positioning frame, the outer side wall of the positioning frame is rotatably connected with a steel bar positioning roller, and an annular groove is provided at the center position of the outer side wall of the steel bar positioning roller, when clamping, the two groups of steel bars are placed above the steel bar positioning roller, the steel bars pass through the steel bar positioning roller from the outer end, and the end thereof extends between the two groups of lower clamping plates and the upper clamping plates, and the positions of the two groups of steel bar positioning rollers are moved together by the lower clamping plate or the upper clamping plate, so that one steel bar passes through closely against the top surface of the lower clamping plate, and the other steel bar passes through closely against the bottom surface of the upper clamping plate.

[0007] Preferably, the outer side wall of the lifting platform is fixedly connected with a slide rail, and the lower clamping plate and the upper clamping plate are both slidably engaged with the lifting platform via the slide rail.

[0008] Preferably, the side walls of the lower clamp and the upper clamp are fixedly connected with laser detectors, the outer side walls of the two lifting platforms are fixedly connected with support frames, and the lifting platforms are placed on the ground through the support frames. When the steel bars are delivered to the designated position, the laser detector sends out an alarm, which facilitates the control of the length of the two steel bars connected.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, a steel bar positioning roller is connected to an upper clamping plate on one side, and the steel bar is closely attached to the bottom surface of the upper clamping plate and extends to the docking position through the annular groove in the steel bar positioning roller. Another steel bar positioning roller is connected to the lower clamping plate on the other side, and the steel bar is closely attached to the top surface of the lower clamping plate and extends to the docking position through the annular groove of the steel bar positioning roller. The hand-held knob is used to control the rotation of the fixed plate. When the sliding seat and the connecting column retreat and move away from the lifting platform, the connecting column pulls the two groups of connecting rods into a horizontal line. Therefore, the two steel bars approach each other with the upper clamping plate and the lower clamping plate until the two steel bars are clamped together. The annular groove in the steel bar positioning roller ensures that the steel bars will not be offset when docking, thereby achieving the effect of accurate positioning and docking of the steel bars.

[0015] 2. In the utility model, two groups of steel bar positioning rollers are respectively connected to the bottom of the telescopic column and the telescopic cylinder. According to the weight of the steel bar, the telescopic column can be pulled out appropriately to extend the distance between the two groups of steel bar positioning rollers. The steel bar is overlapped on the top of the two steel bar positioning rollers. The larger the spacing between the steel bar positioning rollers, the larger the support range of the steel bar butt feeding, thereby reducing the problem of gravity deformation when the steel bar is butt-jointed, avoiding the influence on the welding positioning, and further improving the accuracy of the steel bar positioning.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1

[0024] like Figure 1-4 As shown, the utility model provides a steel bar welding clamping device for construction, comprising two lifting platforms 2, the surfaces of the two lifting platforms 2 are slidably connected with a lower clamping plate 3 and an upper clamping plate 4, the outer walls of the lower clamping plate 3 on one side of the lifting platform 2 and the upper clamping plate 4 on the other side are fixedly connected with a telescopic cylinder 6, the inner wall of the telescopic cylinder 6 is slidably connected with a telescopic column 5, the bottom walls of the telescopic column 5 and the telescopic cylinder 6 are fixedly connected with a positioning frame 18, the outer walls of the positioning frame 18 are rotatably connected with a steel bar positioning roller 10, and an annular groove is provided at the center position of the outer wall of the steel bar positioning roller 10.

[0025] The specific settings and functions of this embodiment are described in detail below. When welding steel bars, a part of the ends of the two steel bars to be welded overlaps, so that more solder can be applied to the gap between the two steel bars. Therefore, two sets of lifting platforms 2 are set. When clamping, the two sets of steel bars are placed above the steel bar positioning roller 10. The steel bars pass through the steel bar positioning roller 10 from the outer ends, and their ends extend between the two sets of lower clamping plates 3 and upper clamping plates 4. The positions of the two sets of steel bar positioning rollers 10 are moved together with the lower clamping plate 3 or the upper clamping plate 4, so that one steel bar passes through the top surface of the lower clamping plate 3, and the other steel bar passes through the bottom surface of the upper clamping plate 4. The overlapping part of the two steel bars is located between the two sets of lifting platforms 2. The positions of the lower clamping plate 3 and the upper clamping plate 4 are adjusted on the lifting platform 2 so that the two steel bars are respectively attached to the upper surface of the lower clamping plate 3 and the lower surface of the upper clamping plate 4 and are close to each other until the two steel bars are clamped together. During the welding operation, the steel bar welding operation can be completed by applying solder to the steel bars connected between the two sets of lifting platforms 2.

[0026] Embodiment 2

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the outer wall of the lifting platform 2 is fixedly connected with a slide rail 16, and the lower clamping plate 3 and the upper clamping plate 4 are slidably connected with the lifting platform 2 through the slide rail 16. The side walls of the lower clamping plate 3 and the upper clamping plate 4 are fixedly connected with a laser detector 15, and the outer walls of the two lifting platforms 2 are fixedly connected with a support frame 1. One end of the lower clamping plate 3 and the upper clamping plate 4 penetrates the lifting platform 2 and is connected with a tail rod 8, and a fixed plate 9 is fixedly connected between the two lifting platforms 2.

[0028] A threaded screw 11 is rotatably connected at the center of the side wall of the fixed plate 9, and a sliding seat 14 is threadedly connected to the outer wall of the threaded screw 11. Connecting columns 17 are fixedly connected to both sides of the sliding seat 14, and two connecting rods 7 are rotatably connected to the outer wall of the connecting column 17, and the connecting rod 7 is rotatably connected to the tail rod 8. A knob 12 is fixedly connected to one end of the threaded screw 11, and a positioning column 13 is fixedly connected to the side wall of the fixed plate 9, and the sliding seat 14 is slidably connected to the positioning column 13.

[0029] The effect achieved by the entire embodiment is that the lifting platform 2 is placed on the ground through the support frame 1. In order to conveniently control the lower clamping plate 3 and the upper clamping plate 4 to clamp each other to achieve the butt welding, the tail rod 8 is connected to the back of the lower clamping plate 3 and the upper clamping plate 4. The distance between the two tail rods 8 is controlled by the connecting rod 7. The rotation angle of the two groups of connecting rods 7 is controlled by the push of the connecting column 17. Therefore, a fixed plate 9 for positioning is set between the two lifting platforms 2. The hand-held knob 12 is used to control the rotation of the fixed plate 9. The sliding seat 14 is limited by the two groups of positioning columns 13, so the rotation of the threaded screw 11 can push the sliding seat 14 forward or backward. When the sliding seat 14 is moved forward or backward, the sliding seat 14 can be moved forward or backward. When the moving seat 14 and the connecting column 17 move forward and approach the lifting platform 2, the connecting column 17 stretches the two groups of connecting rods 7 into a vertical line, and the two groups of tail rods 8 separate to both ends. When the sliding seat 14 and the connecting column 17 retreat and move away from the lifting platform 2, the connecting column 17 pulls the two groups of connecting rods 7 into a horizontal line, and the two groups of tail rods 8 move toward the middle, so as to achieve the clamping effect of the lower clamping plate 3 and the upper clamping plate 4 on the steel bars. A laser detector 15 is set on the lower clamping plate 3 and the upper clamping plate 4 on both sides to detect the steel bar port feeding in from the other side. When the steel bar is fed to the specified position, the laser detector 15 sounds an alarm to facilitate the control of the length of the two steel bars connected.

[0030] The use method and working principle of the device: First, a group of steel bars are overlapped above the steel bar positioning roller 10, and the steel bars are pushed toward the lifting platform 2. As the steel bar positioning roller 10 rolls, the steel bars move toward the middle through the annular groove, and the steel bars pass closely against the bottom surface of the upper clamping plate 4 until the laser detector 15 on the upper clamping plate 4 at the other end issues an early warning, and the movement of the steel bars is stopped;

[0031] Similarly, another set of steel bars is overlapped on the steel bar positioning roller 10, and the steel bars pass closely against the top surface of the lower clamping plate 3 until the laser detector 15 arranged on the lower clamping plate 3 at the other end issues an early warning, and the position of the steel bars is fixed in the same way;

[0032] Then, the knob 12 is held to control the rotation of the fixed plate 9, and the sliding seat 14 is limited by the two groups of positioning columns 13. When the sliding seat 14 and the connecting column 17 retreat and move away from the lifting platform 2, the connecting column 17 pulls the two groups of connecting rods 7 into a horizontal line, and the two groups of tail rods 8 move closer to the middle, and the upper surface of the lower clamping plate 3 and the lower surface of the upper clamping plate 4 move closer to each other until the two steel bars are clamped together;

[0033] Finally, the welding operation is performed by simply applying solder to the steel bars butted between the two sets of lifting platforms 2 .

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
