Description

Technical Field

[0001] This utility model relates to the field of bridge pier support casting technology, and more specifically, to a bridge support anchor bolt hole positioning device. Background Technology

[0002] In bridge engineering, the quality of the anchorage connection between bridge bearings and piers directly affects structural safety. Traditional construction methods require pre-embedding PVC pipes to form anchor bolt holes before pouring the pier concrete. However, due to construction errors and formwork deformation, quality problems such as anchor bolt hole misalignment and insufficient hole depth often occur. Furthermore, gaps easily form between the PVC pipe and the bearing base plate, leading to incomplete grouting and severely impacting the bearing's load-bearing capacity. Existing technology uses rectangular frame positioning fixtures, spatially positioning the PVC pipe by pre-setting fixing slots within the frame. However, the positioning accuracy of this method depends on the initial installation position of the frame. When the pier top surface is not flat enough or there are deviations in the construction layout, the spatial position of the fixing slots cannot be independently adjusted, resulting in a systematic deviation between the actual anchor bolt hole position and the requirements of the construction drawings. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a bridge bearing anchor bolt hole positioning device to solve the aforementioned problems.

[0004] This utility model is implemented as follows: A bridge bearing anchor bolt hole positioning device includes a mounting frame. The mounting frame includes a first frame and a second frame arranged vertically, with four support plates connected between them. The top of the first frame has two first mounting parts symmetrically arranged, and clamping components are provided on the first mounting parts. The top of the second frame has four second mounting parts symmetrically arranged, and anchor bolt hole positioning components are provided on the second mounting parts. The anchor bolt hole positioning components include a first movable plate hinged to the second mounting part and a second movable plate movably disposed on the first movable plate.

[0005] Furthermore, a bracket plate is provided on the top of the first mounting part, and guide holes are provided on both sides of the bracket plate.

[0006] Furthermore, the clamping assembly includes a movable clamping plate. Two first guide rods are provided on one side of the movable clamping plate near the center, and second guide rods are provided near both sides. The first guide rods pass through the support plate from the inside of the first frame, and handles are connected to the ends of the two first guide rods. Abutment springs are provided on the first guide rods, and the two ends of the abutment springs abut against the movable clamping plate and the support plate, respectively. The second guide rods are movably disposed in adjacent guide holes.

[0007] Furthermore, the second frame has a two-layer structure, consisting of frame a and frame b.

[0008] Furthermore, the second mounting part includes a mounting plate disposed between the frame a and the frame b, and an arc-shaped platform is provided on the inner side of the mounting plate near the bottom.

[0009] Furthermore, the anchor bolt hole positioning assembly includes a first movable plate, one end of which is hinged to the arc-shaped platform. A first locking groove is provided on the top of the first movable plate near its hinge point. A first positioning clamp is provided on the bottom of the arc-shaped platform, and the first positioning clamp passes through the top of the first locking groove.

[0010] Furthermore, symmetrical arc-shaped movable arms are arranged on both sides of the first movable plate near its hinge, the arc-shaped movable arms penetrate the mounting plate, a limit rod is provided at the top end of the arc-shaped movable arm, and an arc-shaped movable groove is opened at the top of the frame a to accommodate the movement of the limit rod.

[0011] Furthermore, the top of the first movable plate is provided with an embedded groove, the outline shape of which is the same as that of the second movable plate. A second locking groove is provided at one end of the embedded groove near the first positioning caliper, and movable shafts are provided on both sides of the other end of the embedded groove.

[0012] Furthermore, the second movable plate is movably disposed in the embedded groove, and a second positioning clamp is disposed between the first movable plate and the second movable plate, which extends from below the second locking groove to the top of the second movable plate, and the other end of the second movable plate is slidably disposed on the two movable shafts.

[0013] Furthermore, a limit cylinder is provided at the top center position of the second movable plate.

[0014] The beneficial effects of this utility model are as follows: The mounting frame is fixed to the outside of the pad stone template support by the clamping assembly. The movable clamping plate automatically clamps the template sidewall under the action of the contact spring, completing the overall positioning of the device. For each anchor bolt hole positioning component, a two-stage fine-tuning structure is adopted: First, the first positioning clamp is released, allowing the first movable plate to swing laterally along the arc platform for adjustment, and then locked after adjustment; then the second positioning clamp is released, pushing the second movable plate to move axially along the inner groove to achieve precise front-to-back positioning. Finally, the PVC pipe is fixed by the limiting cylinder, and the rubber protrusion ensures that the pipe body is centered and in close contact. This device forms a two-dimensional adjustment degree of freedom by independently adjusting the lateral swing angle and longitudinal position of each positioning component. Even if there is unevenness on the top surface of the pier or construction layout error, the positioning deviation can still be compensated by fine adjustment, so that the actual anchor bolt hole position accurately matches the design drawing requirements.

The second guide rods 2102 are movably arranged in adjacent guide holes.

[0023] In this embodiment, the second frame 13 has a two-layer structure, namely frame a1301 and frame b1302.

[0024] like Figure 4 As shown, the second mounting part 14 includes a mounting plate 1401 disposed between the frame a1301 and the frame b1302, and an arc-shaped platform 1402 is provided on the inner side of the mounting plate 1401 near the bottom.

[0025] like Figure 4-5The anchor bolt hole positioning assembly 30 includes a first movable plate 31. One end of the first movable plate 31 is hinged to the arc-shaped platform 1402. A first locking groove 3101 is provided on the top of the first movable plate 31 near its hinge. A first positioning clamp 33 is provided on the bottom of the arc-shaped platform 1402. The first positioning clamp 33 passes through the top of the first locking groove 3101. The first locking groove 3101 is a groove-shaped structure. That is, when the first positioning clamp 33 is released, the first movable plate can move left and right within a small range.

[0026] In this embodiment, arc-shaped movable arms 3103 are symmetrically arranged on both sides of the first movable plate 31 near its hinge. The arc-shaped movable arms 3103 penetrate the mounting plate 1401. A limit rod 3104 is provided at the top end of the arc-shaped movable arms 3103.

[0030] In a preferred embodiment, the limiting cylinder 3201 has a protrusion inside, which is made of rubber. Its main function is to increase the clamping and fixing of the PVC pipe by the flexible material. Specifically, the working principle of this bridge bearing anchor bolt hole positioning device is as follows: During use, the device is placed above the pad stone template support. The clamping components 20 are then pulled open to both sides and placed outside the template for clamping and fixing. Further, the position of each anchor bolt hole positioning component 30 is checked to ensure it corresponds to the design drawings. A two-stage adjustment is used to fine-tune the position of the limiting cylinder 3201. Specifically, the first positioning clamp 33 is loosened, and the direction of action of the first movable plate 31 is adjusted to fix it. Then, the second positioning clamp 34 is loosened, and the front-back direction of the second movable plate 32 is adjusted. This two-stage fine-tuning corrects the position of the anchor bolt hole positioning component 30. Through this structure, the problem of existing positioning clamps where the fixing slots used to fix PVC pipes cannot be adjusted independently when the initial frame fixation deviates, leading to deviations between the actual anchor bolt hole position and the requirements of the construction drawings, is solved.
