Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a positioning device. Background Technology

[0002] In the construction of anchorages for suspension bridges, prestressed anchoring systems are often used to anchor the main cables. The prestressed ducts and anchor plates of the prestressed anchoring system are pre-embedded in the anchor blocks at a preset inclination angle (both the prestressed ducts and anchor plates are inclined upwards). After the anchor blocks are cast and formed, the steel strands connected to the main cables are threaded through the prestressed ducts and tensioned onto the anchor plates. Finally, concrete is poured into the prestressed ducts to seal them. Therefore, the installation angle of the prestressed ducts and anchor plates directly determines the direction of stress on the steel strands. If the installation angle deviates from the preset inclination angle, the prestressing direction of the steel strands will deviate from the design direction, affecting the stress distribution of key components such as the main beam and main cable. This may cause localized stress concentration in the suspension bridge, thereby weakening the overall load-bearing capacity of the structure. Therefore, the accuracy of the installation position of the prestressed ducts and anchor plates is crucial.

[0003] In existing technology, when installing prestressed ducts, a support is set up at a predetermined position for the prestressed duct, and the prestressed duct is erected on the support. Then, a positioning frame is installed at the upper end of the prestressed duct, with three observation points set on the frame, located at the top and left and right sides of the prestressed duct. The coordinates of the three observation points are then observed, and the coordinates of the center point of the prestressed duct are calculated based on these coordinates. By comparing these coordinates with the predetermined center point coordinates, the installation position of the prestressed duct can be adjusted so that the coordinates of the center point at the upper end of the prestressed duct are consistent with the predetermined center point coordinates. In actual construction, prestressed ducts are usually composed of multiple ducts spliced ​​together, requiring the installation and splicing of multiple ducts one by one to form a prestressed duct system. If the above installation method is used, it only measures and adjusts the coordinates of the center point of the installed prestressed duct's upper end, and cannot control the spatial angle connection between ducts. Even if the coordinates of a single duct section are correct, the overall axis after splicing may still have angular deviations, easily causing installation errors in the ducts. This results in the prestressed duct installation direction differing from the preset installation direction, causing the prestressing direction of the steel strands to deviate from the design direction, affecting the stress distribution of key components of the suspension bridge (such as the main beam and main cable). In addition, the coordinates of the prestressed duct's center point are obtained through indirect calculation, which is easily affected by the precision of the positioning frame and the installation position, resulting in significant errors.

[0040] This embodiment provides a positioning device, such as Figures 1 to 7 As shown, using this positioning device to position the anchoring system 1 of the suspension bridge can improve installation accuracy, control the installation direction of the pipe 122, effectively avoid angular deviations during pipe 122 splicing, reduce installation errors of the pipe 122, and also reduce the workload of workers.

[0041] like Figure 3As shown, the anchoring system 1 of the suspension bridge includes a first anchor plate 11, a prestressed pipe 12, and a second anchor plate 13, which are sequentially spliced ​​together. Both the first anchor plate 11 and the second anchor plate 13 have mounting slots, and the inner cavity of the prestressed pipe 12 is directly opposite the mounting slot. The prestressed pipe 12 includes multiple sleeves 121 and multiple pipes 122. Adjacent pipes 122 are connected to each other, to the first anchor plate 11, and to the second anchor plate 13 via a sleeve 121. The inner diameter of the mounting slot is the same as the inner diameter of the sleeve 121. Therefore, multiple pipes 122 are spliced ​​together by multiple sleeves 121, and a sleeve 121 is spliced ​​at each end of the pipe 122, thus forming the prestressed pipe 12. The two sleeves 121 at each end are respectively spliced ​​to the first anchor plate 11 and the second anchor plate 13.

[0042] like Figures 1 to 3 As shown, the positioning device is configured for positioning the anchoring system 1 of a suspension bridge. The positioning device includes a positioning base 2, a predictor 3, and a target 4. The cross-sectional area of ​​the positioning base 2 is the same as that of the mounting slot. The positioning base 2 can be selectively fastened to the opening of the sleeve 121 or into the mounting slot, such that the centroid of the positioning base 2 is collinear with the centroid of the sleeve 121 or with the centroid of the mounting slot. A through hole 21 is provided at the centroid of the positioning base 2. The predictor 3 can be selectively connected to the positioning base 2, and is perpendicularly connected to the centroid of the positioning base 2. The length of the predictor 3 is the same as the length of the pipe 122, and an insertion hole 321 is provided at the end of the predictor 3 facing away from the positioning base 2. The target 4 can be selectively inserted into the through hole 21 or the insertion hole 321.

[0043] When positioning the anchoring system 1, firstly, one sleeve 121 is perpendicularly spliced ​​to the first anchor plate 11 so that the sleeve 121 and the first anchor plate 11 are centroidally collinear. Simultaneously, the other sleeve 121 is perpendicularly spliced ​​to the second anchor plate 13 so that the sleeve 121 and the second anchor plate 13 are centroidally collinear. Then, according to the preset installation direction of the prestressed pipe 12, the first anchor plate 11 is installed on the anchoring template, with the sleeve 121 spliced ​​to the first anchor plate 11 in an upward inclined state, and the opening of the sleeve 121 facing the main cable of the suspension bridge. Then, the positioning... The base 2 is fastened to the opening of the sleeve 121 on the first anchor plate 11, and the target 4 is inserted into the through hole 21. The coordinates of the target 4 at this time are measured using a measuring device. The coordinates of the target 4 at this time are the actual center point coordinates of the opening of the sleeve 121. The coordinates of the target 4 at this time are recorded as the first coordinates. If the first coordinates are inconsistent with the preset center point coordinates of the opening of the sleeve 121, the installation position of the first anchor plate 11 is adjusted until the measured first coordinates are consistent with the preset center point coordinates of the opening of the sleeve 121, thus completing the first coordinate adjustment.

[0044] After completing the first coordinate adjustment, the positioning base 2 and the target component 4 are disassembled and removed. Then, the prediction component 3 and the positioning base 2 are connected, and the target component 4 is inserted into the insertion hole 321. The positioning base 2 is then fastened to the opening of the sleeve 121 on the first anchor plate 11. The coordinates of the target component 4 at this time are measured and recorded as the second coordinates. The second coordinates are the coordinates of the center point of the pipe opening of the pipe 122 that will be spliced ​​with the sleeve 121. The second coordinates are compared with the theoretical coordinates of the pipe opening of the pipe 122 that will be spliced ​​with the sleeve 121. If the two are inconsistent, the installation position of the first anchor plate 11 is adjusted until the measured second coordinates are consistent with the theoretical coordinates. This completes the second coordinate adjustment. This adjustment is the initial adjustment of the center point coordinates of the pipe opening of the pipe 122 that will be spliced ​​with the sleeve 121, as well as the prediction of the direction of the pipe 122.

[0045] After completing the second coordinate adjustment, the positioning base 2, the prediction component 3, and the target component 4 are disassembled and removed. A pipe 122 and another new sleeve 121 are spliced ​​on the sleeve 121. The above operation is repeated until all pipes 122 are spliced. The sleeve 121 connected to the second anchor plate 13 is spliced ​​with the last pipe 122. Then, the positioning base 2 is fastened into the mounting hole groove of the second anchor plate 13, and the target component 4 is inserted into the through hole 21. The coordinates of the target component 4 at this time are measured and recorded as the third coordinate. The third coordinate of the target component 4 is compared with the preset center point coordinate of the second anchor plate 13. If the two are inconsistent, the installation position of the first anchor plate 11 is adjusted until the measured second coordinate is consistent with the theoretical coordinate. This completes the third coordinate adjustment. This adjustment is a second adjustment of the center point coordinate of the pipe opening of the installed pipe 122. Finally, the positioning base 2 and the target component 4 are disassembled to complete the positioning work of the anchoring system 1.

[0046] By attaching the positioning base 2 to the opening of the installed sleeve 121 and inserting the target component 4, the installation position of the installed sleeve 121 can be adjusted to ensure it matches the preset installation position. After adjusting the position of the sleeve 121, the prediction component 3 is vertically connected to the centroid of the positioning base 2, and the target component 4 is inserted onto the prediction component 3. Then, the positioning base 2 is attached to the opening of the sleeve 121 again, allowing for further adjustment of the installed structure's position and improving installation accuracy. Simultaneously, the prediction component 3 provides installation guidance, directly indicating the theoretical installation direction of the pipe 122 to be spliced, ensuring the accuracy of the pipe 122 splicing direction and reducing cumulative deviations. By controlling the spatial orientation of the prediction component 3, workers can control the installation direction of the pipe 122, effectively avoiding angular deviations during pipe 122 splicing, preventing the prestressing direction of the steel strands from deviating from the design direction, and avoiding impacting the stress distribution of key components of the suspension bridge. In addition, the center point coordinates of the sleeve 121 opening and the pipe 122 opening are obtained by direct measurement, which can reduce installation errors.

[0047] For example, the target component 4 includes a prism insert, and the measuring device includes a total station.

[0048] In this embodiment, when installing the first anchor plate 11 onto the anchoring template, a bolt can be used to pass through the first anchor plate 11 and the anchoring template and be threadedly connected with a nut. In other embodiments, when installing the first anchor plate 11 onto the anchoring template, the first anchor plate 11 is first attached to the anchoring template, and a snap-fit ​​connector is provided on one of the first anchor plate 11 and the anchoring template. Then, the snap-fit ​​connector is snapped onto the other one; this is not limited to this method.

[0049] Optionally, such as Figure 2 , Figure 4 and Figure 5 As shown, the predictor 3 includes a vertically connected mounting base 31 and a predictor rod 32. The centroid of the mounting base 31 is collinear with the centroid of the predictor rod 32, and the mounting base 31 can be connected to the positioning base 2 so that the centroid of the mounting base 31 coincides with the centroid of the positioning base 2. The predictor rod 32 is adjustable in axial length, and an insertion hole 321 is provided at the end of the predictor rod 32 facing away from the mounting base 31. When predicting the installation direction of the next pipe 122 to be spliced, the prediction component 3 needs to be vertically connected to the centroid of the positioning base 2. This connection is achieved by connecting the mounting base 31 to the positioning base 2. The prediction rod 32 is perpendicular to the mounting base 31, and therefore also perpendicular to the positioning base 2. If the positioning base 2 is fastened to the opening of the sleeve 121, the inclination direction of the prediction rod 32 indicates the predicted installation direction of the next pipe 122 to be spliced. Workers can directly observe and determine whether the predicted installation direction of the pipe 122 matches the designed installation direction. Simultaneously, a target can also be used... The target 4 is inserted into the insertion hole 321 on the prediction rod 32. The coordinates of the target 4 are measured to ensure they match the preset center point coordinates of the pipe opening of the pipe 122 to be spliced. If the predicted installation direction is inconsistent with the designed installation direction of the pipe 122, or if the measured coordinates of the target 4 are inconsistent with the preset center point coordinates, adjustments can be made by adjusting the installation position of the first anchor plate 11. Adjusting the spatial point coordinates and spatial direction allows for more precise control of the installation direction of the pipe 122, effectively avoiding angular deviations during pipe 122 splicing, preventing the prestressing direction of the steel strands from deviating from the design direction, and avoiding affecting the stress distribution of key components of the suspension bridge. In addition, the length of the prediction rod 32 is adjustable along the axial direction, allowing it to predict the installation direction of pipes 122 of different lengths, thus possessing strong versatility.

[0050] Optionally, the positioning device also includes a connector and a fastener. The connector is located on the side of the mounting base 31 opposite to the prediction rod 32 and is collinear with the centroid of the mounting base 31. The connector passes through the through hole 21 and is threadedly connected to the fastener. When connecting the mounting base 31 and the positioning base 2, simply stack the two together, insert the connector through the through hole 21, and then thread it to the fastener. The structure is simple and easy to operate.

[0051] For example, the connector includes a screw, and the fastener includes a fastening nut.

[0052] Optionally, the prediction rod 32 includes a first rod body and a second rod body. One end of the first rod body is connected to the mounting base 31, and the other end is hollow. One end of the second rod body extends into the first rod body and is threaded to the inner wall of the first rod body. The end of the second rod body away from the first rod body is provided with an insertion hole 321. When the length of the pipe 122 to be spliced ​​is short, the required length of the prediction rod 32 is also short. The second rod body can be screwed into the first rod body to reduce the overall length of the prediction rod 32. When the length of the pipe 122 to be spliced ​​is long, part of the second rod body can be screwed out of the first rod body to increase the overall length of the prediction rod 32. The adjustment method is simple and the operation is convenient.

[0053] In some embodiments, the positioning device further includes a limiting plug, and the prediction rod 32 includes a third rod and a fourth rod. One end of the third rod is connected to the mounting base 31, and the other end of the third rod is hollow and has multiple through holes 2 spaced apart along the axial direction. One end of the fourth rod has multiple through holes 3 spaced apart along the axial direction and extends into the third rod. The limiting plug is inserted into the through holes 2 and 3, and the other end of the fourth rod is provided with an insertion hole 321. When it is necessary to increase or decrease the length of the prediction rod 32, it is only necessary to pull out or insert part of the second rod into the first rod, and then insert the limiting plug into the through holes 2 and 3. The structure is simple and the operation is simple.

[0054] Optionally, such as Figure 1 , Figure 3 and Figure 6 As shown, the positioning device also includes at least one lifting lug 5, which is disposed on the positioning base 2. When it is necessary to fasten the positioning base 2 to the opening of the sleeve 121 or to the mounting hole, the operator can hold the lifting lug 5 to fasten the positioning base 2 to the opening of the sleeve 121 or to the mounting hole. The lifting lug 5 can be used to support and keep the positioning base 2 stable in the opening of the sleeve 121 or to the mounting hole. When it is necessary to disassemble the positioning base 2, it can also be disassembled by holding the lifting lug 5. By setting the lifting lug 5, a foundation for the operator to apply force can be provided. The structure is simple and easy to operate.

[0055] In this embodiment, two lifting hooks 5 are provided. In other embodiments, one or more lifting hooks 5 may be provided as needed, and this is not limited here.

[0056] Optionally, such as Figure 1 , Figure 3 and Figure 7 As shown, the positioning base 2 has a circumferentially protruding locking boss 6 on the side opposite to the predictor 3. The locking boss 6 can be selectively locked in the inner cavity of the sleeve 121 or in the mounting hole groove. By setting the locking boss 6, the positioning base 2 can be stably fastened to the opening of the sleeve 121 or in the mounting hole groove, avoiding measurement errors caused by the movement of the positioning base 2 during the measurement process and improving the accuracy of the measurement results.

[0057] Optionally, such as Figure 7 As shown, a reinforcing structure 7 is provided on the side of the positioning base 2 that is away from the predictor 3. By providing the reinforcing structure 7, the strength of the positioning base 2 can be enhanced, preventing measurement errors caused by deformation of the positioning base 2 and ensuring the accuracy of the measurement results.
