Description

Technical Field

[0001] This application relates to the field of engineering construction, and in particular to a measuring device and method for measuring curved track beam formwork. Background Technology

[0002] Straddle-type monorail transit is one of the main forms of urban rail transit. As the PC track beam that directly supports the straddle-type monorail train, it serves as the guide and running track for the train. The various dimensional indicators of its prefabrication directly affect the train's operational safety and passenger comfort; therefore, PC track beams must undergo rigorous testing before prefabrication.

[0003] Traditional surveying for straight PC track beam prefabrication primarily uses the total station centerline method for planar measurement. However, this method cannot accurately measure the curvature deviation of the beam formwork centerline. Instead, the total station coordinate method is typically used to indirectly measure and estimate the deviation of curved beam formwork. This method is highly susceptible to errors from prism positioning and polar coordinate propagation, resulting in low accuracy. Furthermore, this traditional method measures a limited number of beam formwork sections and points, leading to low density and inaccurate measurement of the curved bridge's alignment. Additionally, workers cannot see the theoretical inspection lines of the formwork and must passively adjust it based on the surveyor's instructions and experience, resulting in low efficiency and failing to meet the needs of large-scale modern curved PC track beam production. Summary of the Invention

[0004] This application provides a curved track beam template measuring device and method to solve the technical problems of low measurement accuracy and low efficiency in traditional curved track beam prefabrication measurement methods in related technologies.

[0005] In a first aspect, a measuring device for a curved track beam template is provided, comprising:

[0006] Two travel tracks are used to be installed on the beam formwork retaining wall, and the curvature of the travel tracks is consistent with the curvature of the track beam, and the center lines of the two travel tracks coincide with the center line of the track beam;

[0007] The detection device, which is movably mounted on a travel track, includes lateral detection components and planar detection components;

[0008] An adjustment device is installed between the traveling track and the beam formwork retaining wall for adjusting the position of the traveling track and the detection device;

[0009] In use, the lateral detection component coincides with the theoretical inner wall edge of the track beam template, and the planar detection component is in contact with the top surface of the track beam template.

[0010] In some embodiments, the detection device is slidably mounted on the travel track via a walking section.

[0011] In some embodiments, the walking unit includes a walking wheel and a walking frame, the walking frame being fixed to one end of the detection device near the walking track, the walking wheel being rotatably connected to the end of the walking frame away from the detection device, and the walking wheel being slidably mounted on the walking track.

[0012] In some embodiments, the detection device includes a detection rod whose length direction is perpendicular to the tangent direction of the curved track, and the detection rod is arranged parallel to the plane containing the curved track.

[0013] In some embodiments, the planar detection element includes a graduated detection ruler, which is set perpendicular to the detection rod and slides on the detection rod via a digital vernier. The end of the detection ruler away from the detection rod is used to abut against the top of the track beam template.

[0014] In some embodiments, there are two planar detection elements, which are respectively located at both ends of the detection rod along the length of the detection rod.

[0015] In some embodiments, the end of the measuring ruler that abuts against the track beam template has a pulley.

[0016] In some embodiments, the detection rod has a groove arranged along its length;

[0017] The lateral detection component includes a laser and a fixing component. The laser is slidably disposed in the groove, and the fixing component is connected to the laser and is used to fix the laser in the groove.

[0018] In some embodiments, the adjustment device includes:

[0019] The mounting groove includes a bottom groove and a side groove fixedly connected to the end of the bottom groove away from the beam formwork retaining wall. The end of the bottom groove away from the side groove is used to connect with the beam formwork retaining wall, and the end of the bottom groove with the side groove is movably connected to the traveling track.

[0020] The vertical adjustment part includes a vertical adjustment bolt, which is inserted into the bottom groove, and the end of the vertical adjustment bolt away from the nut abuts against the bottom surface of the travel track;

[0021] The planar adjustment part includes a planar adjustment bolt, which passes through the side groove and the end of the planar adjustment bolt away from the nut abuts against the side of the travel track.

[0022] Secondly, a method for measuring curved track beam templates is provided, which includes the following steps:

[0023] Provide a curved track beam template measuring device as described in any of the above descriptions;

[0024] Install a walking track on the beam formwork retaining wall;

[0025] Detection and adjustment devices are installed on the walking track;

[0026] Adjust the adjustment device to make the two traveling tracks equal in height and to make the center line of the two traveling tracks coincide with the center line of the track beam;

[0027] Adjust the detection device so that the lateral detection component coincides with the theoretical inner wall edge of the track beam template, and the planar detection component is in contact with the top surface of the track beam template;

[0028] The values ​​of the inner wall and elevation of the track beam template measured by the testing device are compared with the theoretical values, and adjustments are made accordingly.

[0029] The beneficial effects of the technical solution provided in this application include:

[0030] This application provides a curved track beam formwork measuring device and method. Since two walking tracks are set on the beam formwork retaining wall, the measuring device can walk along the length of the track, and the center lines of the two walking tracks coincide with the center line of the track, which can accurately reflect the curvature change of the theoretical center line of the formwork.

[0031] During measurement, the track beam template is placed in the track, waiting for pouring. In order to ensure the accuracy of the pouring position, an arc-shaped walking track with the same curvature as the theoretical center line of the track beam is used. The center line of the arc-shaped walking track is used as the reference line of the theoretical center line of the curved track beam template to be poured. It has the advantages of high precision and accurate curve shape, which is conducive to improving the measurement accuracy of straddle-type curved PC track beam prefabrication.

[0032] Furthermore, since the detection device includes lateral detection components and planar detection components, the lateral detection components coincide with the theoretical inner wall edge of the track beam template, and the planar detection components are in contact with the top surface of the track beam template. If the setting position of the track beam template is incorrect, it can be observed through the deviation between the detection components and the actual template, which is simple and clear.

[0033] Meanwhile, the measuring device travels along the arc-shaped track and can continuously measure the track beam template. Compared with the traditional method of measuring the alignment of curved bridges by taking a few sections or points, it is more efficient. Therefore, it can solve the technical problems of low measurement accuracy and low efficiency of traditional curved track beam prefabrication measurement methods in related technologies.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] This application provides a measuring device and method for curved track beam templates, which can solve the technical problems of low measurement accuracy and low efficiency of traditional curved track beam prefabrication measuring methods in related technologies.

[0047] See Figures 1 to 9 As shown, this application embodiment provides a curved track beam formwork measuring device. The measuring device is set in a preset track, and the track has a beam formwork retaining wall 1 for setting the track beam formwork 2. Specifically, the measuring device includes two walking tracks 4, a detection device 3 set on the walking tracks 4, and an adjustment device 7.

[0048] Among them, two walking tracks 4 are set on the beam formwork retaining wall 1. The curvatures of the two walking tracks 4 are matched and they are set side by side. The curvature of the walking tracks 4 is consistent with the curvature of the track beam. The center lines of the two walking tracks 4 coincide with the center line 10 of the track beam.

[0049] Specifically, the center lines of the two walking tracks 4 are as follows: Figure 1 As shown, it coincides with the center line 10 of the track beam and will change as the track beam bends;

[0050] It should be noted that the above "the curvature of the travel track 4 is consistent with the curvature of the track beam" means that after mutual matching, the travel track 4 is parallel to the track beam or has the same inner and outer curvature.

[0051] Combination Figure 9 As shown, Figure 9 This is a top view of the two running tracks 4 and the centerline 10 of the track beam. The positional relationship between them can be seen. Taking the center of the concentric circle formed by the centerline 10 of the track beam and the running track 4 as the center of curvature, under the condition that the centerline 10 of the track beam is parallel to the running track 4 or has the same inner and outer curvature, the curvature increases sequentially around the center of curvature from the direction closest to the centerline 10 to the direction furthest from the centerline 10, with smaller inner curvature and larger outer curvature. Specifically, if the track beam is arc-shaped, the center of curvature corresponds to the center of the concentric circle formed by the centerline 10 of the track beam and the running track 4.

[0052] Furthermore, the detection device 3 is movably mounted on the travel track 4, including a lateral detection component 5 and a planar detection component 6. The lateral detection component 5 is used to coincide with the theoretical inner wall edge of the track beam template 2, and the planar detection component 6 is used to contact the top surface of the track beam template 2. In use, the lateral detection component 5 coincides with the theoretical inner wall edge of the track beam template 2, and the planar detection component 6 contacts the top surface of the track beam template 2. The travel track 4 is used to support the movement of the detection device 3 and to continuously detect the track beam template 2.

[0053] Furthermore, the adjustment device 7 is set between the walking track 4 and the beam formwork retaining wall 1 for adjusting the position of the walking track 4 and the detection device 3. For example, the adjustment device 7 can level the walking track 4 so that the two walking tracks 4 are on the same horizontal plane, thereby enabling the detection device 3 to move horizontally.

[0054] This application provides a curved track beam formwork measuring device. Since two walking tracks 4 are set on the beam formwork retaining wall 1, the detection device 3 can walk along the length direction of the track, and the center line of the two walking tracks 4 coincides with the center line of the track, which can accurately reflect the curvature change of the theoretical center line of the formwork.

[0055] During measurement, the track beam template 2 is placed in the track and awaits pouring. In order to ensure the accuracy of the pouring position, an arc-shaped walking track 4 with the same curvature as the theoretical center line of the track beam is used. The center line of the arc-shaped walking track 4 is used as the reference line of the theoretical center line of the curved track beam template 2 to be poured. It has the advantages of high precision and accurate curve shape, which is conducive to improving the measurement accuracy of straddle-type curved PC track beam prefabrication.

[0056] Furthermore, since the detection device 3 includes a lateral detection component 5 and a planar detection component 6, the lateral detection component 5 coincides with the theoretical inner wall edge of the track beam template 2, and the planar detection component 6 contacts the top surface of the track beam template 2. If the setting position of the track beam template 2 is incorrect, it can be observed through the deviation between the detection component and the actual template, which is simple and clear.

[0057] Meanwhile, the measuring device travels along the arc-shaped track 4 and can continuously measure the track beam template 2. Compared with the traditional method of measuring the alignment of curved bridges by taking a few sections or points, it is more efficient. Therefore, it can solve the technical problems of low measurement accuracy and low efficiency of the traditional curved track beam prefabrication measurement method in related technologies.

[0058] In some alternative embodiments, see Figure 1 and Figure 2 As shown, the detection device 3 includes a walking part 32, and can be slidably mounted on the walking track 4 via the walking part 32;

[0059] Optionally, combined Figure 2As shown, the walking unit 32 includes a walking wheel 322 and a walking frame 321. The walking frame 321 is fixed to one end of the detection device 3 near the walking track 4. The walking wheel 322 is rotatably connected to the end of the walking frame 321 away from the detection device 3, and the walking wheel 322 is connected to the walking track 4, so that the detection device 3 can walk on the walking track 4.

[0060] Preferably, the size of the traveling wheel 322 matches the size of the traveling track 4. When the track bends, the traveling part 32 will not be misaligned, which can better achieve the purpose of accurately reflecting the curvature change of the template theoretical center line.

[0061] In some alternative embodiments, see Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, the detection device 3 includes a detection rod 31. As the detection rod 31 slides on the travel track 4, the length direction of the detection rod 31 is perpendicular to the tangent direction of the curved track or perpendicular to the length direction of the straight track.

[0062] Optionally, the lateral detection element 5 and the planar detection element 6 are mounted on the detection rod 31. The detection rod 31 is provided with a traveling part 32, which is slidably connected to the traveling track 4. Furthermore, the traveling track 4 is connected to the beam formwork retaining wall 1 as follows: Figure 1 As shown, they are located on the same vertical plane, so the lateral detection element 5 and the plane detection element 6 can move as the detection rod 31 moves, and can continuously measure the lateral inner wall and top surface of the track beam template 2.

[0063] In some alternative embodiments, see Figure 1 ,as well as Figures 3 to 5 As shown, the planar inspection component 6 includes a graduated inspection ruler 61, specifically, in conjunction with... Figure 1 As shown, the measuring ruler 61 is set perpendicular to the measuring rod 31, that is, the measuring ruler 61 is perpendicular to the top surface of the track beam template 2. The staff can read the distance from the measuring rod 31 to the track beam template 2 through the scale on the measuring ruler 61, and compare it with the theoretical elevation to determine whether there is an error, so as to facilitate further adjustment.

[0064] Optionally, the measuring ruler 61 is slidably mounted on the measuring rod 31 to accommodate different widths, ensuring that the bottom end of the measuring ruler 61 can continuously contact the top end of the track beam template 2 to achieve the measurement purpose;

[0065] For the measurement of the measuring ruler 61, this application provides an implementation method, namely as follows: Figure 1 and Figure 3As shown, a digital display vernier 62 is provided at the connection between the measuring ruler 61 and the measuring rod 31, so that the measuring ruler 61 can move along the length direction of the measuring rod 31; at the same time, the measuring ruler 61 can move in a direction perpendicular to the measuring rod 31 through the digital display vernier 62, so as to move up and down to contact the top of the track beam template 2. The digital display vernier 62 and the measuring ruler 61 can be clamped, so that while the measuring ruler 61 can move up and down, the digital display vernier 62 can also fix the measuring ruler 61.

[0066] Combination Figure 1 and Figure 4 As shown, one end of the measuring ruler 61 is connected to the digital vernier 62, and the other end abuts against the top of the track beam template 2. The digital vernier 62 is used to display the reading of the measuring ruler 61 in real time. As the measuring rod 31 moves, the plane measuring piece 6 measures the height of the templates on both sides of the beam and compares it with the theoretical elevation of the top surface of the beam to achieve the measurement effect.

[0067] In some alternative embodiments, see Figure 4 and Figure 5 As shown, the end of the measuring ruler 61 away from the measuring rod 31 is connected to a pulley 63, and the sliding direction of the pulley 63 is consistent with the movement direction of the measuring rod 31. The pulley 63 can make the measuring ruler 61 slide along the top surface of the track beam template 2 to detect the top surface value of the track beam template 2 in real time.

[0068] It should be noted that pulley 63 is also included in the length count of the measuring ruler 61, that is, the value displayed by the digital vernier 62 is the vertical distance from the top of the track beam template 2 to the measuring rod 31.

[0069] Preferably, the detection ruler 61 is as follows Figure 1 As shown, there are two, which are respectively set at both ends of the track beam template 2 to avoid unevenness due to the placement of the track beam template 2.

[0070] In some alternative embodiments, see Figure 7 and Figure 8 As shown, the detection rod 31 has a groove 311 arranged along its length direction. The groove 311 can be a strip groove that passes through the detection rod 31 or a groove opened in the detection rod 31.

[0071] Furthermore, the lateral detection component 5 includes a laser 52 and a fixing component 54. The laser 52 is slidably disposed in the slide groove 311, and the fixing component 54 is connected to one end of the laser 52 and the other end is slidably disposed in the slide groove 311.

[0072] Optionally, the lateral detection component 5 includes a roller 53, which is connected between the fixing component 54 and the laser 52. A portion of the roller 53 is located in the slide groove 311, and its movement trajectory coincides with the opening position of the slide groove 311. At this time, the fixing component 54 is engaged in the slide groove 311, so that the lateral detection component 5 will not detach from the detection rod 31, and after it slides to the designated position, it plays a fixing role. Here, the fixing between the fixing component 54 and the slide groove 311 can be achieved by setting a fixing buckle or by the friction between the fixing component 54 and the slide groove 311.

[0073] Optionally, the detection rod 31 is provided with a scale on the edge of the slide groove 311, so that the position of the lateral detection piece 5 can be pre-adjusted according to the width of the track beam template 2.

[0074] Furthermore, the laser 52 is positioned on the side of the detection rod 31 facing the track beam template 2, facilitating the emission of the detection beam 51 towards the track beam template 2, i.e. Figure 1 and Figure 3 As shown

[0075] Furthermore, the embodiments provided in this application include two lateral detection elements 5. The detection beams 51 emitted by the two lateral detection elements 5 are respectively located on the theoretical inner wall edge lines of the templates on both sides of the beam. Workers can determine whether the track beam template 2 deviates from the theoretical position by observing whether the detection beams 51 coincide with the inner wall line of the track beam template 2.

[0076] It can be seen that the aforementioned lateral detection component 5 and planar detection component 6 can be connected to the inner wall and top surface of the theoretical track beam template 2, thus achieving the purpose of real-time detection.

[0077] In some alternative embodiments, see Figure 1 and Figure 2 As shown, the adjustment device 7 includes a mounting groove 71, a vertical adjustment part, and a horizontal adjustment part, combined with... Figure 2 As shown, the mounting groove 71 is used for the installation of the travel track 4. The vertical adjustment part is connected to both the mounting groove 71 and the travel track 4 to adjust the elevation of the travel track 4. The horizontal adjustment part is also connected to both the mounting groove 71 and the travel track 4 to adjust the installation position of the travel track 4 on the plane.

[0078] Optionally, combined Figure 2 As shown, the installation groove 71 is a U-shaped groove, specifically including a bottom groove 711 and a side groove 712. The bottom groove 711 is connected to the beam formwork retaining wall 1, and the side of the bottom groove 711 away from the beam formwork retaining wall 1 is connected to the side groove 712. The side groove 712 and the bottom groove 711 form a space for accommodating the walking track 4, which facilitates the placement of the walking track 4 and the setting of the vertical adjustment part and the horizontal adjustment part.

[0079] Furthermore, combined Figure 2As shown, the vertical adjustment part includes a vertical adjustment bolt 72, which is inserted into the bottom groove 711. One end of the nut of the vertical adjustment bolt 72 serves as the force application end, and the end of the vertical adjustment bolt 72 away from the force application end abuts against the travel track 4.

[0080] Specifically, there can be one vertical adjusting bolt 72. The purpose of lifting the walking track 4 can be achieved by rotating the vertical adjusting bolt 72, so as to adjust the elevation of the walking track 4 and ensure that the height of the two walking tracks 4 is consistent, thereby ensuring that the detection device 3 always remains horizontal.

[0081] In one preferred embodiment, there are at least two vertical adjusting bolts 72, and as shown... Figure 2 As shown, the detection rods 31 are inserted into the bottom grooves 711 along their length to provide more stable support.

[0082] Furthermore, combined Figure 2 As shown, the planar adjustment part includes a planar adjustment bolt 73, which passes through the side groove 712 and is similar to the vertical adjustment bolt. The planar adjustment bolt 73 is as follows: Figure 2 The diagram shows a nut, with one end of the nut serving as the force-applying end, and the end of the plane adjusting bolt 73 away from the force-applying end abutting against the travel track 4;

[0083] Specifically, the planar adjustment section can be as follows: Figure 2 The device shown has a plane adjusting bolt 73. By rotating the plane adjusting bolt 73, the distance between the nut of the plane adjusting bolt 73 and the side groove 712 can be adjusted, thereby controlling the travel track 4 to be adjusted along the length direction of the detection rod 31.

[0084] Of course, the same plane adjustment part can have two plane adjustment bolts 73, and the two plane adjustment bolts 73 are respectively arranged on both sides of the travel track 4 along the length direction of the detection rod 31. While adjusting the travel track 4 along the length direction of the detection rod 31, the travel track 4 can also be limited between the two plane adjustment bolts 73 to achieve further fixation.

[0085] It should be noted that the U-shaped mounting groove 71 can be made up of multiple groove segments spliced ​​together. After being connected into a whole, the bending direction of the mounting groove 71 is consistent with the curvature of the center line of the curved track beam.

[0086] Optionally, combined Figure 2 As shown, a pad 74 is provided between the adjustment device 7 and the travel track 4. The pad 74 is preferably fixedly connected to the travel track 4. At the same time, the width of the pad 74 along the length of the detection rod 31 is smaller than the width of the bottom groove 711, which provides the travel track 4 with adjustment space on the plane and increases the contact area between the travel track 4 and the adjustment device 7, making the connection between the two more stable.

[0087] In some alternative embodiments, see 1 and Figure 2 As shown, a track support column 8 is provided between the beam formwork retaining wall 1 and the walking track 4 for the setting of the walking track 4. Due to the height of the beam formwork retaining wall 1 and the top of the adjusting device 7 and the walking track 4, the track support column 8 is provided to install the walking track 4 and the adjusting device 7.

[0088] This application also provides a method for measuring the template of a curved track beam, which includes the following steps:

[0089] Provides a curved track beam template measuring device as described above;

[0090] S1. Install the walking track 4 on the beam formwork retaining wall 1;

[0091] Optionally, combined Figure 1 As shown, the center line 10 of the track beam is located in the center of the two walking tracks 4, serving as the reference line for the movement of the detection device 3. The walking tracks 4 are set on the beam formwork retaining wall 1.

[0092] Furthermore, there are two walking tracks 4, which are arranged parallel to each other along the extension direction of the two beam formwork retaining walls 1, and there is a center line between the two walking tracks 4. This center line coincides with the center line 10 of the aforementioned track beam, that is, the curvature of the two is the same, which can be used as a reference line for positioning the track beam formwork 2.

[0093] It should be noted that when setting the walking track 4, the position of the walking track 4 is set according to the theoretical position and theoretical radius of curvature of the center line 10 of the track beam, as well as the theoretical set relationship between the walking track 4 and the center line 10 of the track beam. It is important to note that the curvature of the walking track 4 is consistent with the curvature of the track beam, and the center lines of the two walking tracks 4 coincide with the center line 10 of the track beam.

[0094] S2. Install a detection device 3 and an adjustment device 7 on the walking track 4;

[0095] Specifically, in combination Figure 1 and Figure 2 As shown, firstly, an adjustment device 7 is set between the beam formwork retaining wall 1 and the traveling track 4, and then a detection device 3 is installed on the traveling track 4. Optionally, a track support column 8 can be set on the beam formwork retaining wall 1. The track support column 8 and the beam formwork retaining wall 1 can be fixed by bolt connection, which also facilitates disassembly later.

[0096] Furthermore, the adjusting device 7 and the track support column 8 can be bolted together or glued together, and the adjusting device 7 and the track support column 8 can be disassembled together for reuse.

[0097] S3. Adjust the adjusting device 7 to make the two walking tracks 4 at the same height and make the center line of the two walking tracks 4 coincide with the center line 10 of the two track beams.

[0098] Specifically, since the detection device 3 is set up on the walking track 4, a level can be installed on the detection device 3 to determine whether the detection device 3 is in a horizontal state, that is, to determine whether the two walking tracks 4 are at the same height.

[0099] Optionally, the adjustment device 7 includes a mounting groove 71, a vertical adjustment part, and a horizontal adjustment part, combined with... Figure 2 As shown, the mounting groove 71 is used for the installation of the travel track 4. The vertical adjustment part is connected to both the mounting groove 71 and the travel track 4 to adjust the elevation of the travel track 4. The horizontal adjustment part is also connected to both the mounting groove 71 and the travel track 4 to adjust the installation position of the travel track 4 on the plane.

[0100] Furthermore, combined Figure 2 As shown, the vertical adjustment part includes a vertical adjustment bolt 72, which is inserted into the bottom groove 711. One end of the nut of the vertical adjustment bolt 72 serves as the force application end, and the end of the vertical adjustment bolt 72 away from the force application end abuts against the travel track 4. The purpose of lifting the travel track 4 is achieved by rotating the force application end of the vertical adjustment bolt 72.

[0101] Similarly, combining Figure 2 As shown, the planar adjustment part includes a planar adjustment bolt 73, which passes through the side groove 712 and is similar to the vertical adjustment bolt. The planar adjustment bolt 73 is as follows: Figure 2 The device has a nut, with one end of the nut serving as the force-applying end. The end of the plane adjusting bolt 73 away from the force-applying end abuts against the travel track 4. By rotating the plane adjusting bolt 73, the distance between the nut of the plane adjusting bolt 73 and the side groove 712 is adjusted, thereby controlling the travel track 4 to be adjusted along the length direction of the detection rod 31.

[0102] S4. Adjust the detection device 3 so that the lateral detection piece 5 coincides with the theoretical inner wall edge of the track beam template 2, and the planar detection piece 6 is in contact with the top surface of the track beam template 2.

[0103] Specifically, the lateral detection component 5 includes a laser 52. After the installation and adjustment of the detection device 3 are completed, the laser 52, which is located in the slide groove 311, is slid to make the detection beam 51 emitted by the laser 52 be aligned with the inner wall edge of the side plate 21 of the track beam template 2.

[0104] As the detection device 3 slides from one end of the track beam template 2 along the walking track 4 to the other end of the track beam template 2, the detection beam 51 of the laser 52 visually detects the deviation between the actual inner wall edge line and the theoretical inner wall edge line of the side plate 21 of the entire track beam template 2. It should be noted that the deviation can be determined by manual observation or by automatic machine recognition.

[0105] Furthermore, while the lateral detection component 5 is functioning, the two planar detection components 6 are opened, and the bottom end of the detection ruler 61 contacts the top end of the track beam template 2. Specifically, the detection ruler 61 is perpendicular to the detection rod 31 and slides along the top surface of the track beam template 2 along with the movement of the detection rod 31, thereby detecting the elevation of the top end of the track beam template 2 in real time. The specific height data can be obtained by observing the scaled detection ruler 61 or by the display screen of the digital vernier 62.

[0106] S5. Based on the values ​​of the inner wall and elevation of the track beam template 2 measured by the detection device 3, compare them with the theoretical values ​​and make adjustments.

[0107] Specifically, in combination Figure 1 As shown, a jack 9 is installed between the track beam formwork 2 and the beam formwork retaining wall 1. By using the deviation between the plane position and elevation obtained in step S4, the jack 9 is used to push the side plate 21 to adjust the plane position of the track beam formwork 2.

[0108] Meanwhile, the track beam formwork 2 includes a base plate 22, which is set on a support frame. If the elevation of the track beam formwork 2 is incorrect, the elevation of the track beam formwork 2 can be corrected by adjusting the support frame.

[0109] Specifically, in combination Figure 1 As shown, one end of the jack 9 is connected to the beam formwork retaining wall 1, and the other end abuts against the track beam formwork 2.

[0110] This application provides a measuring device and method for curved track beam formwork. By setting a walking track 4 on the beam formwork retaining wall 1 that matches the curvature of the track beam, the detection device 3 moves along the walking track 4 to complete continuous detection and accurately reflect the curvature change of the theoretical center line of the formwork. The line shape is accurate and the continuity is high, which is beneficial to improving the measurement accuracy of straddle-type curved PC track beam prefabrication.

[0111] In addition, the embodiment of this application uses a laser 52 to directly display the theoretical detection line of the template, allowing operators to directly observe the template deviation, which is simple and clear. At the same time, as the detection slide bar moves, the curved track beam template 2 can be visually adjusted at multiple points, greatly improving the template adjustment efficiency.

[0112] Furthermore, the embodiments of this application employ a measuring ruler 61 to continuously mark the elevation of the curved track beam template, which is convenient and intuitive, and improves the accuracy and efficiency of beam height measurement.
