Description

Technical Field

[0001] This utility model belongs to the field of component installation and adjustment technology, and relates to verticality control devices, particularly a verticality control device for high piers. Background Technology

[0002] Precast bridge construction has developed rapidly in China. Precast components require high installation precision, and precast piers come in various sizes and heights. A steel plate is placed at the center between the pier and the abutment for load-bearing, and high-strength mortar is laid around the perimeter for connection. Strict control of the pier's verticality is necessary during installation.

[0003] A search revealed a Chinese patent document disclosing a precast pier verticality adjustment structure [Application No.: CN202420924840.6; Publication No.: CN222313804U]. This structure includes a precast pier, a foundation, a central pad, foundation reinforcement bars, and adjusting shims. The adjusting shims include circular shims and U-shaped shims. The circular shims are pre-fitted onto the foundation reinforcement bars before the precast pier is hoisted, and the U-shaped shims are slidably inserted onto the foundation reinforcement bars after the precast pier is hoisted. In this invention, before hoisting the precast pier, circular shims of different thicknesses or numbers are pre-fitted onto the foundation reinforcement bars at different positions to control the overall top surface height and achieve a preliminary leveling effect. After grouting, the precast pier is lowered, and its verticality is measured. If a small deviation in verticality still exists, different numbers of U-shaped shims can be slidably inserted from the side of the foundation reinforcement bars at different positions to quickly adjust the verticality.

[0004] Although the precast pier verticality adjustment structure disclosed in this patent can effectively adjust the verticality by inserting different numbers of U-shaped shims, as the number of inserted U-shaped shims increases, subsequent U-shaped shims need to be hammered with a tool to completely fit onto the pier cap reinforcement. However, the U-shaped shims are small in size, and the space between the precast pier and the pier cap is narrow. In this narrow space, hammering is restricted by space, and it is easy to lose precise control of the hammering. The operation is difficult and inefficient. Therefore, it is necessary to design a high pier verticality control device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a high pier verticality control device. The technical problem to be solved by this utility model is: how to more easily insert U-shaped shims into the pier cap reinforcement bars in a confined space.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A verticality control device for a high pier includes a base. An outer frame is fixedly connected to the top of the base. Two first limiting rods are threaded through each of the four sides of the outer frame. The first limiting rods are slidably connected to the outer frame. Two first limiting rods at the same end are fixedly connected to the same push plate. A pressure plate is fixedly connected to one side of the push plate. The side of the pressure plate away from the push plate is an inclined surface. The pressure plate passes through the outer frame and is slidably connected to the outer frame. Eight second limiting rods are fixedly connected to the top of the base. Two second limiting rods form a group. Two second limiting rods at the same end are fitted with the same lifting plate. The lifting plate is slidably connected to the second limiting rods. A lower pressure plate is fixedly connected to the bottom of the lifting plate. The lower pressure plate is located at the top of the inclined surface. A strike block is fixedly connected to the top of the lifting plate.

[0008] The working principle of this utility model is as follows: the impact block is continuously struck by a heavy object such as a hammer, causing it to descend. The impact block then drives the lifting plate to descend, and the lifting plate descends along the second limit rod to ensure stability during its movement. The descent of the lifting plate also drives the lower pressure plate to descend, and the lower pressure plate contacts the inclined surface on the pressure plate. The pressure plate then presses against the inclined surface of the pressure plate, causing it to move laterally. This lateral movement of the pressure plate drives the push plate to move, which in turn drives the first limit rod to move, ensuring stability during its movement. The movement of the push plate compresses the U-shaped gasket, causing it to fit onto the rib of the support platform.

[0009] The outer frame has square slots on all four sides, and the pressure plate is placed in the square slots.

[0010] Two first circular holes are provided on each of the four sides of the outer frame. The first circular holes are adapted to the first limiting rods, and the first limiting rods are set in the first circular holes.

[0011] With the above structure, the first limiting rod will move along the first circular hole when it moves, ensuring the stability of the first limiting rod when it moves.

[0012] The bottom of the lifting plate is fixedly connected to two cylinders, which are sleeved on the second limiting rod and are slidably connected to the second limiting rod.

[0013] With the above structure, the lifting plate will drive the cylinder to move along the second limit rod, ensuring the stability of the lifting plate when moving up and down, and enabling stable up and down movement.

[0014] The base is fixedly connected to a support platform at its bottom, and a number of support platform inserts are fixedly connected to the top of the support platform. The support platform inserts pass through the base, and a number of second circular holes are provided on the base, which are adapted to the support platform inserts.

[0015] A central pad is provided on the top of the base, and a U-shaped pad is provided on the top of the base at the position of the support rib.

[0016] Several of the aforementioned pile cap reinforcing bars are fitted with the same precast pier column.

[0017] Compared with the prior art, the verticality control device for high piers of this utility model has the following advantages:

[0018] In this invention, by employing a technique that transforms lateral force into vertical force to hammer the U-shaped gasket, the installation of the U-shaped gasket is achieved by using a tool to strike the impact block, causing it to descend. This allows the lower pressure plate to descend and contact the inclined surface of the pressure plate, enabling the pressure plate to move laterally. The pressure plate then drives the push plate to move and contact the U-shaped gasket, hammering it inward. Vertical force is easier to control and does not deviate from the predetermined direction, avoiding hammering deviation or errors caused by limited space. This effectively solves the problem in the background art where, as the number of inserted U-shaped gaskets increases, subsequent U-shaped gaskets require hammering to fully fit onto the foundation reinforcement. However, the U-shaped gaskets are small, and the space between the precast pier and the foundation is narrow. In this confined space, hammering is restricted, making it easy to lose precise control, resulting in high operational difficulty and low efficiency. This invention effectively reduces operational difficulty and risk, facilitating the installation of U-shaped gaskets in confined spaces and ensuring installation efficiency.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figure 1 - Figure 4 As shown, a high pier verticality control device includes a base 2, an outer frame 3 fixedly connected to the top of the base 2, two first limiting rods 4 passing through each of the four sides of the outer frame 3, the first limiting rods 4 slidably connected to the outer frame 3, two first limiting rods 4 at the same end fixedly connected to the same push plate 5, a pressure plate 6 fixedly connected to one side of the push plate 5, the side of the pressure plate 6 away from the push plate 5 being an inclined surface 601, the pressure plate 6 passing through the outer frame 3, the pressure plate 6 slidably connected to the outer frame 3, eight second limiting rods 7 fixedly connected to the top of the base 2, two second limiting rods 7 forming a group, two second limiting rods 7 at the same end fitted with the same lifting plate 8, the lifting plate 8 slidably connected to the second limiting rods 7, a lower pressure plate 9 fixedly connected to the bottom of the lifting plate 8, the lower pressure plate 9 being set at the top of the inclined surface 601, a strike block 10 fixedly connected to the top of the lifting plate 8, and the outer frame 3... Square slots 301 are provided on all four sides, and pressure plates 6 are placed in the square slots 301. Two first circular holes 302 are provided on all four sides of the outer frame 3. The first circular holes 302 are adapted to the first limiting rods 4. The first limiting rods 4 are placed in the first circular holes 302. Two cylinders 801 are fixedly connected to the bottom of the lifting plate 8. The cylinders 801 are sleeved on the second limiting rods 7. The cylinders 801 are slidably connected to the second limiting rods 7. The bottom of the base 2 is fixedly connected to the support platform 1. Several support platform reinforcing bars 12 are fixedly connected to the top of the support platform 1. The support platform reinforcing bars 12 pass through the base 2. Several second circular holes 201 are provided on the base 2. The second circular holes 201 are adapted to the support platform reinforcing bars 12. A central pad 11 is provided on the top of the base 2. A U-shaped pad 13 is provided on the top of the base 2 at the position of the support platform reinforcing bars 12. Several support platform reinforcing bars 12 are sleeved on the same precast pier column 14.

[0026] The working principle of this utility model is as follows: The base 2 is fitted onto the pier cap reinforcing bar 12, and screws are used to fix the base 2 onto the pier cap 1, so that the pier cap reinforcing bar 12 is positioned within the second circular hole 201. The precast pier column 14 is fitted onto the pier cap reinforcing bar 12, with the bottom of the precast pier column 14 contacting the central pad 11. The verticality of the precast pier column 14 is detected using a verticality measuring device. If a small deviation in verticality still exists, different numbers of U-shaped shims 13 are inserted to the sides of the pier cap reinforcing bars 12 at different positions. Then, a hammer or other heavy object is used to continuously strike the impact block 10, causing it to descend. The impact block 10 then drives the lifting plate 8 to descend, and the lifting plate 8 descends along the second limit rod 7. The lowering of the lifting plate 8 ensures stability during movement. The lowering of the lifting plate 8 also causes the lower pressure plate 9 to descend. The lower pressure plate 9 will contact the inclined surface 601 on the pressure plate 6. The lower pressure plate 9 contacts the inclined surface 601 and applies pressure to the pressure plate 6, which allows the pressure plate 6 to move laterally. The lateral movement of the pressure plate 6 will cause the push plate 5 to move, which in turn causes the first limit rod 4 to move, ensuring the stability of the push plate 5 during movement. The movement of the push plate 5 compresses the U-shaped pad 13, causing the U-shaped pad 13 to fit onto the pier rib 12. By changing the direction of force application from lateral striking to vertical striking, vertical striking is easier to operate vertically with tools (such as a hammer). When space is limited, vertical striking is more convenient and easier to achieve.

[0027] In summary, this invention effectively reduces the difficulty and risk of operation, facilitates the installation of U-shaped gaskets in confined spaces, and ensures installation efficiency.
