[0002] Bridge embedded components are an indispensable part of modern bridge construction. They connect and secure bridge components, providing stability and durability. There are various types of bridge embedded components, including embedded bolts, embedded nuts, embedded sleeves, and embedded steel plates, each with its specific purpose. Among them, bridge deck embedded sleeves are arranged in an array on the bridge deck and are used for the future installation of lifting equipment such as bridge erecting machines to stabilize the moving box girders. Therefore, the embedding of these sleeves must be strictly distributed according to the dimensional plan; otherwise, mismatches with the positions of the lifting equipment will occur, significantly affecting the lifting of the box girders and other related work.

[0003] Therefore, to address the above shortcomings, it is necessary to develop a positioning device for the pre-embedded sleeve of the bridge deck. Summary of the Invention

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] A positioning device for a bridge deck pre-embedded sleeve includes a support frame 1, a sliding plate 2, a clamp 3, a connecting rod 4, a level 5, and columns 6. Six columns 6 are threadedly connected to the four corners of the H-shaped support frame 1 and the middle of the front and rear side plates to erect the support frame 1 on the reinforcing cage. The front and rear ends of the sliding plate 2 are slidably connected to the front and rear side plates of the support frame 1, respectively. The clamp 3 is threadedly connected to the bottom of the front end of the sliding plate 2 and clamps the front plate of the support frame 1 together with the sliding plate 2. The connecting rod 4 is slidably connected to the sliding plate 2 and is inserted into or threadedly connected to the pre-embedded sleeve. Several levels 5 are fixedly connected at intervals to the mutually parallel left, middle, and right side plates of the support frame 1.

[0020] The support frame 1 is a H-shaped frame, the level 5 is a liquid column level, and the column 6 is a threaded rod. The six columns 6 are vertical in length direction. A handle 61 is fixedly connected to the top of the column 6. The outer diameter of the handle 61 is larger than the diameter of the column 6 so that the column 6 can be rotated. In conjunction with the level 5, the support frame 1 is adjusted to be level at the end face.

[0021] The slide plate 2 is a long strip-shaped structure. Multiple slide plates 2 can be slidably connected on the support frame 1. The front and rear ends of each slide plate 2 abut against the top surface of the front side plate of the support frame 1 so that the position can be flexibly adjusted. A long strip-shaped groove 21 that runs through the middle of the slide plate 2 is provided. The connecting rod 4 is slidably connected in the groove 21 so that the position of the connecting rod 4 can be flexibly adjusted.

[0022] The clamp 3 has a block-shaped structure. A threaded rod 31 is threadedly connected to the middle of the clamp 3. The top of the threaded rod 31 is rotatably connected to the slide plate 2. By rotating the threaded rod 31, the outward end of the clamp 3 can abut against the bottom of the front or rear side plate of the support frame 1. The clamp 3 and the slide plate 2 together clamp the support frame 1 up and down to fix the position of the slide plate 2.

[0023] A smooth rod 32 is slidably connected to one side of the clamp 3. The length direction of the smooth rod 32 is parallel to the length direction of the threaded rod 31. The top end of the smooth rod 32 is fixedly connected to the bottom of the slide plate 2. The smooth rod 32 stabilizes the movement direction of the clamp 3. The bottom end of the smooth rod 32 passes downward and extends out of the clamp 3. A limiting plate 33 is fixedly connected to the bottom end of the smooth rod 32. The diameter of the limiting plate 33 is larger than the diameter of the smooth rod 32. The limiting plate 33 prevents the clamp 3 from sliding down and dislodging from the threaded rod 31, thus preventing it from being lost. The top end of the threaded rod 31 extends out of the slide plate 2 and is fixedly connected to a knob 34. The diameter of the knob 34 is larger than the diameter of the threaded rod 31 to allow the threaded rod 31 to be rotated.

[0024] The connecting rod 4 is a cylindrical rod. A clamping block 41 is fixedly connected to the bottom of the connecting rod 4 on the slide plate 2. The clamping block 41 has a polygonal structure, and its diameter is larger than the vertical width of the slide groove 21 to prevent the connecting rod 4 from detaching from the slide plate 2. A handle 42 is threadedly connected to the top of the connecting rod 4 on the slide plate 2. The handle 42 and the clamping block 41 together clamp the slide plate 2 to restrict the position of the connecting rod 4.

[0025] Working principle: 1. Fix the pre-embedded sleeve that needs to be positioned onto the connecting rod 4. Measure and mark the installation position of the pre-embedded sleeve on the slide plate 2. Then move the connecting rod 4 to the marked position on the slide plate 2 in the slide groove 21. Then, clamp the slide plate 2 by rotating the handle 42 and the clamping block 41 to complete the initial positioning of the connecting rod 4. 2. Using a laser rangefinder combined with BIM modeling data, place the support frame 1 with column 6 on the bridge deck steel reinforcement where the pre-embedded sleeves need to be installed. By observing the level 5 on the support frame 1, rotate the handle 61 and column 6 to adjust the support frame 1 to be horizontal. If necessary, the column 6 can be tied to the bridge deck steel reinforcement cage or mold. 3. Then install the slide plate 2 onto the support frame 1, and pass the lower end of the light rod 32 through the round hole on the clamp 3. The light rod 32 is used to stabilize the moving direction of the clamp 3. The bottom of the light rod 32 is fixedly connected to the limit plate 33 to prevent the clamp 3 from disengaging from the threaded rod 31. 4. Hold and rotate the knob 34 and the threaded rod 31, so that the threaded rod 31 is screwed downward into the threaded hole on the clamp 3 and passes through the clamp 3. After tightening, the clamp 3 and the slide plate 2 will clamp the support frame 1 together, thus completing the fixation of the slide plate 2. 5. Finally, the embedded sleeve is tied to the reinforcing cage with steel wire. After the restrictions of the connecting rod 4 and the column 6 are released, the embedded sleeve is separated from the positioning device. The positioning device can then be removed all at once. This not only enables rapid positioning of the embedded sleeve, but also saves the work of repeated disassembly, saving time and effort.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
