Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, and in particular to a method for rapid leveling of bridge bearings. Background Technology

[0002] Bridge bearings are an important component of bridges, and their flatness has a significant impact on the safety and stability of the bridge. Industry standards require that the supporting surface of bridge bearings be in a horizontal state during installation. However, traditional bridge bearing leveling methods usually involve manual operation. Since a 1-2cm leveling layer needs to be reserved between the top of the bridge pad stone and the steel plate under the bearing, it is difficult to control the elevation and flatness of the steel plate under the bearing.

[0003] Because the top surface of the bearing pad has already been roughened, wood chips and other supports are commonly used. However, these supports are prone to shifting during installation, leading to discrepancies in elevation and flatness. Repeated adjustments to the supports are necessary, which is inefficient, time-consuming, and prone to errors in measurement and construction, making it difficult to guarantee the leveling accuracy of the bridge bearings and ensuring they reach the required horizontal position after installation. Therefore, we propose a rapid leveling method for bridge bearings. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid leveling method for bridge bearings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] A2: Drill holes for rebar installation according to the marked locations;

[0016] The specific operation procedure for marking is as follows: mark the area inside the reserved hole of the bridge pad stone body, with the longitudinal and transverse center lines of the bridge pad stone body as the standard lines.

[0017] The method for creating the anchor holes is as follows: vertical drilling is performed using a handheld drill.

[0018] Preferably, one end of the leveling component extends 3-10cm beyond the end of the rebar hole; the leveling component is fixed by using rebar adhesive.

[0019] Preferably, the leveling operation procedure includes the following:

[0020] B1: Calculate the installation elevation of the bottom of the steel plate under the bridge bearing;

[0021] B2: Measure the elevation of the top of the leveling component;

[0022] B3: Based on the installation elevation of the bottom of the lower steel plate, remove the excess length of the exposed part of the leveling component;

[0023] B4: Retest the flatness of the leveling components;

[0024] The measuring instrument was a level.

[0025] The removal method involves using a handheld cutting machine, leaving a 3-5mm gap during the cut.

[0026] Preferably, the bridge bearing is installed by hoisting it to the top of the leveling assembly and then securing it.

[0027] Preferably, the leveling operation procedure includes the following:

[0028] B1: Calculate the installation elevation of the bottom of the steel plate under the bridge bearing;

[0029] B2: Measure the elevation of the top of the leveling component;

[0030] B3: Adjust the excess length of the exposed part of the leveling component according to the installation elevation of the bottom of the lower steel plate;

[0031] B4: Retest the flatness of the leveling components;

[0032] The measuring instrument used was a level.

[0033] Preferably, the leveling component is a steel bar end or an adjustable structure;

[0034] The adjustable structure includes a connecting hole disposed on the inner wall of the leveling component, a T-shaped post disposed on the inner wall of the connecting hole, and two or more pads disposed on the outer wall of the T-shaped post.

[0035] Both the connecting hole and the inner wall of the pad are provided with grooves that match the protrusions on the outer wall of the T-shaped column.

[0036] Preferably, a reference line is provided on the outer wall of the T-shaped column near the top, and a horizontal needle is rotatably connected to the outer circumference of the T-shaped column.

[0037] Preferably, the retesting method is to use a level, spirit level, or leveling structure to measure the flatness of the top of the leveling component.

[0038] Preferably, the leveling structure includes an I-beam and a leveling rod fitted onto the outer circumference of the I-beam;

[0039] The outer circumferential wall of the I-beam is provided with a connecting rod, and the inner wall of the connecting rod near one end is provided with a through hole.

[0040] The leveling rod is one of the following shapes: cross-shaped, T-shaped, or strip-shaped.

[0041] The beneficial effects of this invention are as follows:

[0042] 1. This invention involves installing and fixing a leveling component inside the rebar holes on the top surface of the bridge bearing pad. A leveling instrument or similar tool is used to measure the horizontal height of the top of the leveling component. Based on the elevation of the steel plate under the bridge bearing, the elevation of the top of the four rebar heads on the top of the bridge bearing pad is adjusted to ensure the flatness of the top of the leveling component. This controls the flatness and elevation during the bridge bearing installation process, effectively improving construction efficiency, ensuring the quality and leveling accuracy of the bridge bearing installation, and achieving the required level state after installation.

[0043] 2. This invention, through the setting of leveling components, significantly improves the efficiency of bridge bearing installation and construction, preventing displacement of the bridge bearings after grouting; it can control construction quality and ensure that the flatness and elevation of the bearings after installation meet the requirements; this construction method has the advantages of simple operation, wide adaptability, high construction efficiency, and meeting construction quality requirements.

[0044] 3. In this invention, after inserting four leveling components into the anchoring holes, the position of the leveling components is confirmed to be vertically aligned by pointing the two ends of the horizontal pin to the reference line, so that adjustments can be made. Then, the top horizontal height of the four leveling components is measured, and the number of shims is increased or decreased by moving the T-shaped column up and down inside the leveling components, thereby adjusting the overall height of the adjustable structure so that it can be quickly kept level. Finally, the adjustable structure is fixed with anchoring adhesive. The installation is relatively convenient and improves the work efficiency.

[0045] 4. In this invention, the handheld leveling structure is placed above the center of the four leveling components. Then, the through hole at one end of the connecting rod is fitted onto one of the leveling components and adjusted to a suitable position, thereby providing a horizontal support point for the leveling structure. This ensures that the leveling structure is vertical during use. Then, the hand is released, and the cross-shaped leveling rod will move down along the I-beam until its bottom surface contacts the four top surfaces of the leveling component or any of the highest top surfaces. This helps the operator quickly determine whether the top surfaces of the four leveling components are at the same horizontal level, making it convenient to use.

[0046] 5. In this invention, the leveling rod is one of the following shapes: cross-shaped, T-shaped, strip-shaped, etc., which can realize the rapid measurement of the top flatness height of four leveling parts simultaneously, or three parts, two parts, or one part, making it convenient to use.

[0066] Preferably, the method for creating the rebar hole 201 is as follows: the rebar hole 201 is drilled using a handheld drill, and the diameter of the rebar hole 201 is 5cm deep and 1.5cm in diameter.

[0067] Preferably, the anchoring holes 201 are opened according to the vertical principle, and the number of anchoring holes 201 is the same as that of leveling components 2.

[0068] A3: Insert the leveling component 2 into the anchor hole 201 and fix it;

[0069] More preferably, one end of the leveling component 2, which is fixed inside the anchoring hole 201, extends outward by 3-10cm, preferably 5cm, from the end of the anchoring hole 201.

[0070] A further preferred method for fixing the leveling component 2 is to use rebar adhesive to ensure that the rebar head is firmly installed and can achieve high strength after curing, thus meeting the requirements for supporting the bridge structure.

[0072] The preferred leveling procedure includes the following:

[0073] B1: Calculate the installation elevation of the bottom of the steel plate under the bridge bearing;

[0077] A further preferred method of removal is cutting with a handheld cutting machine;

[0078] A further preferred method is to leave a 3-5mm gap during cutting to allow for subsequent grinding of the top of the rebar head to a flat surface, thereby improving the leveling accuracy.

[0079] B4: Retest the flatness of the leveling components;

[0087] In this embodiment, the leveling component is installed and fixed in the anchor hole 201 on the top surface of the bridge pad stone body 1. The top of the leveling component is measured using tools such as a level instrument. The excess length of the exposed part of the leveling component 2 is cut off to ensure the flatness of the top of the leveling component. Then, the flatness of the top of the leveling component is re-measured using a level instrument and a spirit level. The bridge bearing is then hoisted to the top of the leveling component and tightened using the installation method in the prior art.

[0088] This invention adjusts the elevation of the top of the four post-installed steel bars on the top of the bridge bearing body 1 according to the elevation of the steel plate under the bridge bearing, thereby controlling the flatness and elevation during the installation of the bridge bearing, effectively improving construction efficiency and ensuring the quality of bridge bearing installation.

[0089] This invention, through the addition of a leveling component 2, significantly improves the efficiency of bridge bearing installation, preventing displacement after grouting. It also enables quality control, ensuring that the flatness and elevation of the installed bearings meet requirements. This construction method offers advantages such as simple operation, wide adaptability, high efficiency, and compliance with quality requirements.

[0090] Example 2:

[0091] A method for rapid leveling of bridge bearings, such as Figure 2 and Figure 4-6 As shown, in order to quickly level the top of the leveling component, this embodiment makes the following improvements based on embodiment 1: In step S2, the leveling operation process includes the following:

[0092] B1: Calculate the installation elevation of the bottom of the steel plate under the bridge bearing;

[0093] B2: Measure the elevation of the top of leveling component 2;

[0094] B3: Adjust the excess length of the exposed part of the leveling component 2 according to the installation elevation of the bottom of the lower steel plate;

[0095] B4: Retest the flatness of the leveling components;

[0096] The measuring instrument was a level.

[0097] The leveling assembly consists of at least four leveling components 2 with the same structure. Preferably, in this embodiment, the leveling component 2 is an adjustable structure, which includes a connecting hole 206 opened on the inner wall of the circumference of the leveling component 2, a T-shaped post 205 inserted into the inner wall of the connecting hole 206, and a plurality of open-shaped pads 202 sleeved on the outer wall of the T-shaped post 205.

[0098] Preferably, the inner walls of the connecting hole 206 and the pad 202 are provided with grooves 2021 that are adapted to the protrusions on the outer wall of the T-shaped column 205;

[0099] Furthermore, the outer wall of the T-shaped column 205 near the top is printed with a reference line 203. The outer circumference of the T-shaped column 205 covering the reference line 203 is rotatably connected to a horizontal pin 204 via a pivot. After inserting the four leveling pieces 2 into the anchor holes 201, the position of the leveling pieces 2 is confirmed to be vertically aligned by the direction of the two ends of the horizontal pin 204 relative to the reference line 203, so that adjustments can be made. Then, the top horizontal height of the four leveling pieces 2 is measured, and the number of pads 202 is increased or decreased by moving the T-shaped column 205 up and down in the leveling pieces 2, thereby adjusting the overall height of the adjustable structure so that it can be quickly kept level. Then, the adjustable structure is fixed with anchor adhesive. The installation is relatively convenient and the work efficiency is improved.

[0100] The flatness retesting method in B4 is to use a leveling structure to measure the flatness of the top of the leveling component. The leveling structure includes an I-beam 301 and a leveling rod 3 sleeved on the outer circumference of the I-beam 301.

[0101] Furthermore, the leveling rod 3 can be one of the following shapes: cross-shaped, T-shaped, strip-shaped, etc.; it can realize the rapid measurement of the top flatness height of four leveling parts 2 simultaneously, or three, two, or one, which is more convenient to use. In this embodiment, the leveling rod 3 is cross-shaped.

[0102] Furthermore, a connecting rod 302 is sleeved on the outer circumference of the I-beam 301, and a through hole 3021 adapted to the outer wall of the leveling component 2 is opened on the inner wall of the connecting rod 302 near one end.

[0103] Preferably, the connecting rod 302 is located below the leveling rod 3; this facilitates quick connection between the leveling structure and the leveling components, and makes assembly and disassembly convenient. Holding the leveling structure, place it above the center of the four leveling components 2, then fit the through hole 3021 at one end of the connecting rod 302 onto one of the leveling components 2 and adjust it to a suitable position. This provides a horizontal support point for the leveling structure, ensuring it remains vertical during use. Then release the rod; the cross-shaped leveling rod 3 will then slide down along the I-beam 301 until its bottom surface contacts the four top surfaces of the leveling component 2 or any of the highest top surfaces. This helps operators quickly determine whether the top surfaces of the four leveling components 2 are at the same horizontal level, making it convenient to use.

[0104] In this embodiment, a leveling component is installed in the anchoring hole 201 on the top surface of the bridge pad stone body 1. The position of the leveling component 2 is confirmed to be vertically aligned by the direction of the two ends of the horizontal needle 204 relative to the reference line 203, so as to make adjustments and fix the bottom of the leveling component 2 with anchoring adhesive. Then, hold the leveling structure and place it above the center of the four leveling components 2. Then, fit the through hole 3021 at one end of the connecting rod 302 onto one of the leveling components 2 and adjust it to a suitable position, thereby providing a horizontal support point for the leveling structure. This ensures that the leveling structure is vertical during use. Then, release the rod. At this time, the cross-shaped leveling rod 3 will move down along the I-beam 301 until its bottom surface contacts the four top surfaces of the leveling component 2 or any of the highest top surfaces. This helps the operator quickly determine whether the top surfaces of the four leveling components 2 are at the same level. By moving the T-shaped column 205 up and down inside the leveling component 2, the number of pads 202 can be increased or decreased, thereby adjusting the overall height of the adjustable structure so that it can quickly maintain flatness. Then, use anchoring adhesive to fix the adjustable structure to ensure the flatness of the top of the leveling component. Then, hoist the bridge bearing to the top of the leveling component and tighten it using the existing installation method.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
