[0030] Reference Figure 1, an anti-slip positioning device for prefabricated beam assembly, comprising a correction mechanism 1, wherein the correction mechanism 1 is rotatably connected to a telescopic connecting rod 2, the telescopic connecting rod 2 is tilted, and an adapting positioning rod 3 is arranged at one end of the telescopic connecting rod 2 away from the correction mechanism 1, wherein the adapting positioning rod 3 comprises a positioning rod body 31, wherein the positioning rod body 31 is provided with a plurality of positioning slots 311; the positioning rod body 31 is provided with a plurality of positioning clamps 4 for cooperating with the installation of prefabricated beams, the positioning clamps 4 are detachably connected to the positioning slots 311, and a plurality of the positioning clamps 4 are separated to form a positioning cavity. When the anti-slip positioning device is used, the position positioning is completed by using the correction mechanism 1, and the angle positioning is completed by using the telescopic connecting rod 2. By installing the positioning clamps 4 on the adapting positioning rod 3, the positioning clamps 4 form a positioning cavity to adapt to preset beams of different beam widths, thereby achieving fast and accurate positioning.

[0031] Reference Figure 1 and Figure 2 Specifically, the correction mechanism 1 includes a correction block 11, which is provided with a cross positioning groove 111 for reference. The cross positioning groove 111 is used to match the cross ink fountain line at the construction site. The operator moves the correction block 11 so that the cross positioning groove 111 of the correction block 11 coincides with the cross ink fountain line, and the correction block 11 can be pre-positioned. In order to facilitate the cooperation with the telescopic connecting rod 2, side rods 112 are respectively provided on both sides of the correction block 11. The side rods 112 extend in a direction away from the correction block 11 and are arranged horizontally. The length of the side rods 112 is 40-60 mm.

[0032] Correspondingly, the telescopic connecting rod 2 includes a first rod body 21 rotatably connected to the correction block 11 and a second rod body 22 slidably connected to the first rod body 21, and the telescopic connecting rod 2 has an angle with the correction mechanism 1. One end of the first rod body 21 away from the second rod body 22 is detachably connected to the correction block 11. In this embodiment, this end of the first rod body 21 is provided with a rod sleeve 23 corresponding to the side rod 112, and the rod sleeve 23 is sleeved or detached from the side rod 112. At the same time, the side rod 112 is also provided with a locking member for tightening the rod sleeve 23. It can be understood that the side rod 112 can be a threaded rod or a smooth rod, and the rod sleeve 23 corresponds to a threaded sleeve and a smooth sleeve, and the locking member corresponds to a nut or a tightening sleeve that is interference-connected with the side rod 112. By rotating the first rod body 21, the angle between the telescopic connecting rod 2 and the horizontal direction can be adjusted, and then locked and limited by the locking member, and finally the length of the telescopic connecting rod 2 is adjusted to move the adapter positioning rod 3 and the positioning clamp 4 to the preset position.

[0033] The second rod body 22 is sleeved on the first rod body 21. By pulling the first rod body 21 and the second rod body 22 apart, the first rod body 21 can slide out of the second rod body 22 to extend the telescopic connecting rod 2; by pulling the first rod body 21 and the second rod body 22 closer, the first rod body 21 and the second rod body 22 can be combined to shorten the telescopic connecting rod 2. At the same time, in order to fix the telescopic connecting rod 2 after telescoping, the first rod body 21 has a protrusion that can pop up or sink, and the second rod body 22 has a plurality of rod body holes along its length direction, and the position of the protrusion corresponds to the position of the rod body hole. After telescoping, the protrusion will pop up and embed into the rod body hole to achieve limiting; when adjustment is required, the protrusion is pressed to make the protrusion sink, so that the first rod body 21 and the second rod body 22 can be released from limiting.

[0034] One end of the second rod body 22 away from the first rod body 21 is fixedly connected to the positioning rod body 31, and the second rod body 22 can be welded to the positioning rod body 31. The positioning rod body 31 is arranged horizontally, and the length of the positioning rod body 31 is 750-850mm; the positioning slots 311 are evenly arranged along the length direction of the positioning rod body 31, and the slot width of the positioning slots 311 is 4-6mm; the interval between adjacent positioning slots 311 is 18-22mm. By arranging positioning clamps 4 in different positioning slots 311, prefabricated beams with different beam widths can be positioned.

[0035] Reference Figure 3 and Figure 4 The positioning clamp plate 4 includes a first clamp bar 41 and a second clamp bar 42 fixedly connected to the first clamp bar 41, and the first clamp bar 41 and the second clamp bar 42 have a certain angle. The first clamp bar 41 and the second clamp bar 42 can improve the structural strength of the positioning clamp plate 4, and it is not easy to deform or bend when positioning and limiting the prefabricated beam.

[0036] Reference Figure 3 , Figure 4 and Figure 6In order to conveniently install and disassemble with the positioning slot 311, one end of the positioning clamp plate 4 that cooperates with the positioning slot 311 has a positioning block 43, and the positioning block 43 is engaged with or disengaged from the positioning slot 311. The positioning block 43 includes an outer positioning frame 431 and an inner positioning frame 432 engaged with the outer positioning frame 431, and the inner positioning frame 432 has a certain elastic deformation ability. A plurality of spring sections (not shown in the figure) are connected between the outer positioning frame 431 and the inner positioning frame 432, and the plurality of spring sections are evenly distributed along the inner edge of the outer positioning frame 431. The spring sections are located between the outer positioning frame 431 and the inner positioning frame 432, and one end of the spring section is fixedly connected to the outer positioning frame 431, and the other end of the spring section is fixedly connected to the inner positioning frame 432, so that the inner positioning frame 432 can move toward or away from the outer positioning frame 431. When the positioning clamp plate 4 needs to be installed, the inner positioning frame 432 is moved outward to increase the inner diameter, and the inner positioning frame 432 is sleeved in the positioning slot 311 and then released. The inner positioning frame 432 is pressed against the positioning slot 311 by the spring section to achieve fixation. When the positioning clamp plate 4 needs to be removed, the inner positioning frame 432 is moved outward to expand so that the inner positioning frame 432 can be separated from the positioning slot 311. By installing the positioning clamp plate 4 in different positioning slots 311 of the adapting positioning rod 3, positioning cavities of different sizes can be formed to adapt to precast beams of different beam widths.

[0037] Reference Figure 5 In addition, in order to further fix the positioning clamp plate 4, the anti-slip positioning device further includes a positioning buckle 5 sleeved on the matching positioning rod 3, the positioning buckle 5 is interference-connected with the matching positioning rod 3, and the positioning buckle 5 abuts against both sides of the positioning clamp plate 4. When the positioning clamp plate 4 needs to be further fixed, the positioning buckle 5 is sleeved and abutted against both sides of the positioning clamp plate 4.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
