Description

Technical Field

[0001] This application relates to the technical field of installation positioning and adjustment devices, and in particular to an installation positioning and adjustment device for a prefabricated bridge substructure with a socket-type structure. Background Technology

[0002] Traditional bridge construction typically employs on-site concrete casting, a method that is not only time-consuming and costly but also highly susceptible to weather and environmental factors. In recent years, with the development of industrialized construction, the application of precast components has become increasingly widespread, especially in bridge construction. Precast components can significantly improve construction efficiency and quality while reducing construction risks. In the construction of precast assembled bridges, the verticality of the precast piers is a critical control factor. Specifically, during the installation of precast piers, their verticality needs to be adjusted to ensure that the installation meets the verticality requirements.

[0003] In existing prefabricated bridges, the verticality of prefabricated piers is generally controlled by the hammer-ball method. This method involves suspending a heavy hammer with wires at the center point or four predetermined corners of the pier on a working platform. The deviation of the hammer ball from the center point or predetermined point is observed to measure the pier's center offset and torsion, allowing for precise adjustments. While this method is simple and intuitive, it is greatly affected by wind and prone to errors during use. It cannot accurately control the verticality of the prefabricated piers, leading to easy displacement of the piers during installation. Therefore, an improved positioning and adjustment device for the installation of the socket-type substructure of prefabricated bridges is proposed. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a prefabricated assembled bridge socket substructure installation positioning and adjustment device, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: a prefabricated bridge substructure installation positioning and adjustment device, comprising a bridge abutment, two symmetrically arranged installation slots on the top of the bridge abutment, a prefabricated pier column slidably inserted into the installation slot, a prefabricated cap beam one placed on the top of the prefabricated pier column, a prefabricated cap beam two slidably inserted into the interior of the prefabricated cap beam one, an adjustment unit fixedly installed on the upper surface of the bridge abutment on one side of the installation slot, a fixed frame fixedly fitted on the outer surface of the prefabricated pier column, a level measuring instrument fixedly installed on the top of the fixed frame, an installation seat fixedly installed on the outer wall of the fixed frame, a connecting rod rotatably connected inside the installation seat, and the other end of the connecting rod movably connected to the adjustment unit.

[0006] By adopting the above technical solution, during the lowering of the precast pier, the precast pier is supported by a fixed frame, and the verticality of the precast pier is detected by a leveling instrument to check the horizontal state of the fixed frame. When the leveling instrument detects a deviation in the verticality of the precast pier, the verticality of the precast pier is controlled and adjusted by the cooperation between the mounting base, connecting rod, and adjustment unit to ensure that the precast pier can be lowered vertically and accurately into the installation slot. Then, the first and second precast cap beams are assembled in sequence. After the assembly work is completed, concrete is poured at the connection between the bridge abutment and the precast pier, the connection between the precast pier and the first precast cap beam, and the connection between the first and second precast cap beams to fix the precast components together. Since the precast pier, the first precast cap beam, and the second precast cap beam are all cast and manufactured in the factory, only assembly is required on site, which can significantly shorten the on-site construction period.

[0007] As a preferred technical solution of this application, the adjustment unit includes a base fixedly installed on the upper surface of the bridge abutment. An adjustment groove is provided on the upper surface of the base. A slider is slidably connected inside the adjustment groove. A connecting seat rotatably connected to a connecting rod is fixedly installed on the top of the slider. A jack for driving the slider to slide is fixedly installed on one side of the upper surface of the base located in the adjustment groove.

[0008] By adopting the above technical solution, the jack drives the slider to slide inside the adjustment groove to adjust its position. The cooperation between the mounting base, connecting rod and connecting seat is used to transmit force, so that the force of the jack can be applied to the fixed frame to adjust its position. That is, the verticality of the precast pier can be adjusted by changing the position of the fixed frame.

[0009] As a preferred technical solution of this application, a guide rod is slidably inserted into the slider, both ends of which are fixedly installed inside the adjustment groove, and the external dimensions of the slider are adapted to the internal space dimensions of the adjustment groove.

[0010] By adopting the above technical solution, a guide rod is set to provide a stable movement trajectory for the slider, ensuring that the slider will not detach from the inside of the adjustment groove, thus guaranteeing the stability and straightness of the slider movement.

[0011] As a preferred technical solution of this application, a positioning block is fixedly installed on the upper surface of the bridge abutment on one side of the base. A positioning guide wheel is rotatably connected to one end of the positioning block near the precast pier. The outer surface of the positioning guide wheel is in contact with the outer wall of the precast pier.

[0012] By adopting the above technical solution, the lowering of the precast pier column is guided by the cooperation between the positioning block and the positioning guide wheel.

[0013] As a preferred technical solution of this application, a plurality of connecting ribs I are fixedly installed on the inner wall of the mounting groove, and a plurality of connecting ribs II are fixedly installed on the outer wall of the precast pier near the lower end, wherein the connecting ribs I and the connecting ribs II are staggered.

[0014] By adopting the above technical solution, when pouring concrete at the connection between the bridge abutment and the precast pier, the presence of connecting bar one and connecting bar two can improve the tightness of the connection between the bridge abutment and the precast pier.

[0015] As a preferred technical solution of this application, the top of the precast pier is fixedly connected with a straight bar, and the bottom of the precast cap beam is provided with an insertion groove for inserting the straight bar.

[0016] By adopting the above technical solution, when pouring concrete at the connection between the unidirectional precast pier and the precast cap beam, the presence of straight reinforcement can improve the tightness of the connection between the precast pier and the precast cap beam.

[0017] As a preferred technical solution of this application, a first hook is fixedly installed on the top of the first precast cap beam, and a second hook is fixedly installed on the top of the second precast cap beam.

[0018] By adopting the above technical solution, and by setting up hook one and hook two, it is convenient to lift and transfer precast cap beam one and precast cap beam two.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In this invention, during the lowering of the precast pier, a fixed frame supports the pier. A leveling instrument detects the horizontal state of the fixed frame, thereby detecting the verticality of the precast pier. When the leveling instrument detects a deviation in the verticality of the precast pier, a jack drives a slider to slide within an adjustment groove to adjust its position. The cooperation between the mounting base, connecting rod, and connecting seat transmits force, ensuring that the force of the jack is applied to the fixed frame for position adjustment. In other words, the position can be adjusted by changing the fixed frame... The position of the frame is adjusted to ensure the verticality of the precast pier column, so that the precast pier column can be placed vertically and accurately into the installation slot. Then, the first precast cap beam and the second precast cap beam are assembled in sequence. After the assembly work is completed, concrete is poured at the connection between the bridge abutment and the precast pier column, the connection between the precast pier column and the first precast cap beam, and the connection between the first precast cap beam and the second precast cap beam to fix all the precast components together. Since the precast pier column, the first precast cap beam and the second precast cap beam are all cast and manufactured in the factory, only assembly is required on site, which can greatly shorten the on-site construction period.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 - Figure 5As shown in the figure, this embodiment provides a prefabricated assembled bridge substructure installation positioning and adjustment device, including a bridge abutment 1. Two installation slots 2 are symmetrically opened on the top of the bridge abutment 1. Prefabricated piers 3 are slidably inserted into the installation slots 2. A prefabricated cap beam 4 is placed on top of the prefabricated pier 3, and a second prefabricated cap beam 5 is slidably inserted into the prefabricated cap beam 4. An adjustment unit 16 is fixedly installed on one side of the upper surface of the bridge abutment 1, located in the installation slot 2. A fixing frame 12 is fixedly fitted onto the outer surface of the prefabricated pier 3. A level detector 13 is fixedly installed on the top of the fixing frame 12. An installation seat 14 is fixedly installed on the outer wall of the fixing frame 12. A connecting rod 15 is rotatably connected inside the installation seat 14. The other end of the connecting rod 15 is movably connected to the adjustment unit 16. In use, during the lowering of the prefabricated pier 3, the fixing frame 12 supports the prefabricated pier 3. The horizontal state of the fixed frame 12 is detected by the level detector 13, thereby detecting the verticality of the precast pier column 3. When the level detector 13 detects a deviation in the verticality of the precast pier column 3, the verticality of the precast pier column 3 is controlled and adjusted by the cooperation between the mounting base 14, the connecting rod 15 and the adjustment unit 16, to ensure that the precast pier column 3 can be placed vertically and accurately into the installation groove 2. Then, the precast cap beam 1 4 and the precast cap beam 2 5 are assembled in sequence. After the assembly work is completed, concrete is poured at the connection between the bridge abutment 1 and the precast pier column 3, the connection between the precast pier column 3 and the precast cap beam 1 4, and the connection between the precast cap beam 1 4 and the precast cap beam 2 5 to fix the precast components together. Since the precast pier column 3, the precast cap beam 1 4 and the precast cap beam 2 5 are all cast and manufactured in the back-end factory, only assembly is required on site, which can greatly shorten the on-site construction period.

[0031] In this embodiment, as Figure 3-5 As shown, the adjustment unit 16 includes a base 161 fixedly installed on the upper surface of the bridge abutment 1. An adjustment groove 162 is provided on the upper surface of the base 161. A slider 165 is slidably connected inside the adjustment groove 162. A connecting seat 164 rotatably connected to the connecting rod 15 is fixedly installed on the top of the slider 165. A jack 166 is fixedly installed on the upper surface of the base 161 on one side of the adjustment groove 162 to drive the slider 165 to slide. In use, the slider 165 is driven to slide inside the adjustment groove 162 by the jack 166 to adjust its position. The force is transmitted through the cooperation between the mounting seat 14, the connecting rod 15, and the connecting seat 164, so that the force of the jack 166 can be applied to the fixed frame 12 to adjust its position. That is, the verticality of the precast pier 3 can be adjusted by changing the position of the fixed frame 12.

[0032] In this embodiment, as Figure 5As shown, a guide rod 163 is slidably inserted into the inside of the slider 165. Both ends of the guide rod 163 are fixedly installed inside the adjustment groove 162. The external dimensions of the slider 165 are adapted to the internal space dimensions of the adjustment groove 162. In use, the guide rod 163 provides a stable movement trajectory for the slider 165, ensuring that the slider 165 will not detach from the inside of the adjustment groove 162, thus ensuring the stability and straightness of the slider 165 during movement.

[0033] In this embodiment, as Figure 3 As shown, a positioning block 17 is fixedly installed on the upper surface of the bridge abutment 1 on one side of the base 161. A positioning guide wheel 18 is rotatably connected to one end of the positioning block 17 near the precast pier 3. The outer surface of the positioning guide wheel 18 is in contact with the outer wall of the precast pier 3. In use, the positioning block 17 and the positioning guide wheel 18 guide the lowering of the precast pier 3.

[0034] In this embodiment, as Figure 2 As shown, several connecting ribs 10 are fixedly installed on the inner wall of the mounting groove 2, and several connecting ribs 21 are fixedly installed on the outer wall of the precast pier 3 near the lower end. The connecting ribs 10 and 21 are staggered. When concrete is poured at the connection between the bridge abutment 1 and the precast pier 3 during use, the presence of connecting ribs 10 and 21 can improve the tightness of the connection between the bridge abutment 1 and the precast pier 3.

[0035] In this embodiment, as Figure 2 As shown, the top of the precast pier column 3 is fixedly connected with a straight bar 7, and the bottom of the precast cap beam 4 is provided with an insertion groove 6 for the straight bar 7 to be inserted. When concrete is poured at the connection between the unidirectional precast pier column 3 and the precast cap beam 4 during use, the presence of the straight bar 7 can improve the tightness of the connection between the precast pier column 3 and the precast cap beam 4.

[0036] In this embodiment, as Figure 1 As shown, a hook 8 is fixedly installed on the top of the precast cap beam 4, and a hook 9 is fixedly installed on the top of the precast cap beam 5. In use, the precast cap beam 4 and the precast cap beam 5 can be easily hoisted and transferred by setting hook 8 and hook 9.

[0037] The working principle of this utility model is as follows: When using the prefabricated assembled bridge socket-type substructure installation positioning and adjustment device of this application, during the lowering of the prefabricated pier 3, the prefabricated pier 3 is supported by the fixed frame 12. The horizontal state of the fixed frame 12 is detected by the level detector 13, thereby detecting the verticality of the prefabricated pier 3. When the level detector 13 detects a deviation in the verticality of the prefabricated pier 3, the jack 166 drives the slider 165 to slide inside the adjustment groove 162 to adjust its position. The force is transmitted through the cooperation between the mounting base 14, the connecting rod 15, and the connecting base 164, so that the force of the jack 166 can be applied to the target area. The fixed frame 12 is used to adjust the position of the precast pier 3. The verticality of the precast pier 3 can be controlled and adjusted by changing the position of the fixed frame 12, so that the precast pier 3 can be placed vertically and accurately into the installation groove 2. Then, the precast cap beam 1 4 and the precast cap beam 2 5 are assembled in sequence. After the assembly work is completed, concrete is poured into the connection between the bridge abutment 1 and the precast pier 3, the connection between the precast pier 3 and the precast cap beam 1 4, and the connection between the precast cap beam 1 4 and the precast cap beam 2 5 to fix the precast components together. Since the precast pier 3, the precast cap beam 1 4 and the precast cap beam 2 5 are all cast and manufactured in the back-end factory, only assembly is required on site, which can greatly shorten the on-site construction period.
