[0017] Embodiment 1

[0018] As Figures 1 to 3As shown, the adjustable reinforcing bar positioning device based on the positioning steel plate of the preferred embodiment of the utility model, include: positioning steel plate 1, connecting nut 2, centralizing sleeve 3, compression lock nut 4, compression cover 5, locking screw 6, adjusting washer 7 and compression structure, wherein, positioning steel plate 1 is horizontally arranged above concrete cast-in-place component 11, connecting nut 2 is fixedly arranged on the upper surface of positioning steel plate 1, and connecting nut 2 is symmetrically provided with four. Centralizing sleeve 3 is hollow cylindrical structure, centralizing sleeve 3 is vertically arranged above positioning steel plate 1, and the lower end of centralizing sleeve 3 is arranged in connecting nut 2 and is threadedly connected with connecting nut 2, and compression lock nut 4 is threadedly connected with the upper end of centralizing sleeve 3. Reserved reinforcing bar 10 is arranged in centralizing sleeve 3, and the lower end portion is located in concrete cast-in-place component 11. Connecting nut 2 has a large inner diameter, which can ensure that the reserved reinforcing bar 10 of different diameters can smoothly pass through the positioning steel plate 1 and be inserted into the centralizing sleeve 3. Adjusting washer is horizontally arranged at the top of centralizing sleeve 3 and the inner side of compression lock nut 4, and is effectively compressed by compression structure. Adjusting washer is used to adjust the diameter of the through hole of the centralizing sleeve, and meets the passing requirements of reinforcing bars of different diameters.

[0019] Further, the compression structure includes compression cover 5 and locking screw 6, and the compression cover 5 is arranged at the top of the compression lock nut 4 and is pressed on the top of the adjusting washer on the inner side. Four vertical threaded holes are uniformly distributed around the compression lock nut 4, and the locking screw 6 is arranged in the threaded hole. The compression cover 5 is fixedly connected with the compression lock nut 4 by the locking screw 6, and the adjusting washer 7 is compressed. The adjusting washer 7 includes two standard flat washers. The standard flat washer can be a large opening adjusting washer or a small opening adjusting washer, which is used to adjust the size of the positioning hole required by the reserved reinforcing bar of different diameters. The size of the positioning hole can be accurately adjusted according to the diameter of the reinforcing bar. The outer diameter of the adjusting washer 7 matches the inner diameter of the compression lock nut 4.

[0020] Further, the centralizing sleeve 3 is made of a 3mm thick steel pipe, and the cylinder bodies at the upper end and the lower end of the centralizing sleeve 3 are provided with external threads, which are respectively accurately matched with the connecting nut 2 and the compression lock nut 4, to ensure the stability and reliability of the connection, and facilitate the replacement and disassembly of the centralizing sleeve. The lower half of the cylinder body of the centralizing sleeve 3 is symmetrically provided with four horizontal threaded holes in a cross shape, which are used to arrange clamping screws 8. When the clamping screw 8 is screwed inward, it can clamp the reserved reinforcing bar 10 and limit its movement in the vertical direction, realizing the vertical positioning function.

[0021] Example 2

[0022] The use process of the utility model will be introduced as follows:

[0023] 1. Installation preparation: according to the design requirements, the components such as positioning steel plate 1, connecting nut 2, centralizing sleeve 3, compression lock nut 4, compression cover 5, locking screw 6, adjusting washer 7 and clamping screw 8 are prepared, and the specifications and quality of each component are checked to see whether they meet the requirements.

[0024] 2. Assembly process: weld the connecting nut 2 on the positioning steel plate 1, ensure firm welding, screw the lower end of the centralizing sleeve 3 into the connecting nut 2, select two adjusting washers 7 with appropriate hole diameters according to the diameter of the dowel bar, place them inside the compression lock nut 4, place the compression cover 5 on the adjusting washers and the compression lock nut 4, connect the compression cover 5 and the compression lock nut 4 into a whole through the locking screw 6 and tighten, screw the clamping screw 8 into the threaded hole of the lower half of the barrel of the centralizing sleeve 3.

[0025] 3. Positioning operation:

[0026] 1) Horizontal positioning: through the combined use of two adjusting washers 7, for dowel bars of different diameters, appropriate diameter washers can be selected and placed below the compression lock nut 4, the compression lock nut 4 is screwed down, and the adjusting washers 7 are compressed around the reserved dowel bar 10 in cooperation with the compression cover 5 above. When the compression lock nut 4 and the compression cover 5 are connected into a whole through the locking screw 6 and the adjusting washers 7 are compressed, the adjusting washers 7 are in close contact with the reserved dowel bar 10, generating friction force to limit the movement and rotation of the reserved dowel bar 10 in the horizontal direction. Because the hole diameter of the adjusting washer 7 can be flexibly selected according to the diameter of the steel bar, the device can adapt to various specifications of the reserved dowel bar 10, achieving accurate horizontal positioning.

[0027] 2) Vertical positioning: the lower half of the barrel of the centralizing sleeve 3 is designed with four transverse threaded holes, when the clamping screw 8 is screwed in, the clamping screw 8 moves inward until it is in close contact with the reserved dowel bar 10. The extrusion force generated by the clamping screw 8 on the dowel bar prevents the reserved dowel bar 10 from moving vertically, and the friction force balances the vertical force that the reserved dowel bar 10 may receive, thereby achieving vertical positioning. During the concrete pouring process, even if it is impacted and pressed by the concrete, the reserved dowel bar can still maintain at the predetermined vertical position.

[0028] 4. Subsequent construction: after the positioning of the reserved dowel bar is completed, subsequent construction procedures such as concrete pouring are carried out, and during the construction process, the positioning of the dowel bar is checked regularly to ensure the stability of the positioning device and the positioning accuracy of the dowel bar.

[0029] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
