Description

Technical Field

[0001] This disclosure relates to the field of steel anchor beam construction technology, and in particular to a method for assembling and positioning a spatial cable guide tube for a steel anchor beam. Background Technology

[0002] With the vigorous development of my country's road traffic infrastructure construction, steel anchor beams for cable-stayed bridges are being used more and more widely in large steel bridges. Research on the manufacturing of steel anchor beams is developing rapidly in order to meet the requirements of manufacturing precision for steel anchor beams for cable-stayed bridges.

[0003] The manufacturing process requires the production of steel anchor boxes and steel brackets as components. However, the poor positioning angle and matching accuracy of the cable guides in the steel anchor beams during manufacturing fail to meet the required precision. Therefore, inventing safe and reliable assembly tooling and platforms can effectively solve the manufacturing problems of steel anchor beams and ensure the completion of the final assembly production task with high quality and quantity.

[0004] Therefore, it is necessary to improve one or more of the problems existing in the above-mentioned related technical solutions.

[0039] This example embodiment provides a method for assembling and positioning a spatial cable guide for a steel anchor beam. (See reference...) Figure 1 As shown, the method may include steps S101 to S106.

[0040] Step S101: Set up platform 200 on hardened ground, and arrange first longitudinal and transverse reference lines on platform 200; wherein, the first longitudinal and transverse reference lines include a first longitudinal reference line and a first transverse reference line, and the first longitudinal reference line and the first transverse reference line intersect at a point.

[0041] Step S102: Based on the first longitudinal and transverse reference lines on the platform 200, a tooling structure 100 is set up on the platform 200. The tooling structure 100 is used for the assembly and positioning of the cable guide 400.

[0042] Step S103: Lay out the second longitudinal and transverse reference lines 700 on the wall panel 300, and position the steel bracket 800 according to the first longitudinal and transverse reference lines on the platform 200 and the second longitudinal and transverse reference lines 700 on the wall panel 300; wherein, the second longitudinal and transverse reference lines 700 include a second longitudinal reference line 710 and a second transverse reference line 720, and the second longitudinal reference line 710 and the second transverse reference line 720 intersect at a point;

[0043] Step S104: The cable guide 400 is initially laid on the wall panel 300 using the tooling structure 100;

[0044] Step S105: Determine the theoretical projection line of the cable guide 400 on the platform 200 according to the preset transverse bridge axial angle, and draw a baseline plumb line at the intersection of the cable guide 400. Adjust the position of the cable guide 400 in the horizontal direction using the tooling structure 100 so that the baseline plumb line intersects the theoretical projection line; wherein, the preset transverse bridge axial angle is the angle between the theoretical projection line and the first longitudinal reference line on the platform 200;

[0045] Step S106: Adjust the position of the cable guide 400 in the vertical direction according to the preset angle so that the angle between the cable guide 400 and the wall panel 300 is within the angle error range of the preset angle.

[0046] Using the above method, the platform 200 is reasonably arranged on the hardened ground, and a baseline is set. The tooling structure 100 is positioned according to the baseline, and the wall panel 300, steel bracket 800 and cable guide 400 are further positioned, so that the overall structure design is compact and the stability and rigidity meet the requirements. This method is reliable and practical. It transforms the three-dimensional spatial structure into a planar triangular relationship, simplifies the process, and makes it easier for workers to accurately assemble and position the cable guide onto the wall panel of the steel anchor beam.

[0047] Below, we will refer to Figures 1 to 5The assembly and positioning method of the steel anchor beam space cable guide 400 in this example embodiment will be described in more detail.

[0048] In step S101, a platform 200 is laid out on the hardened ground, and a first longitudinal and transverse reference line is arranged on the platform 200; wherein, the first longitudinal and transverse reference lines include a first longitudinal reference line and a first transverse reference line, and the first longitudinal reference line and the first transverse reference line intersect at a point.

[0049] Specifically, when assembling and positioning the steel anchor beam spatial cable guide 400, a platform 200 needs to be laid out first. The platform 200 is laid out on a hardened ground, using H-beams (HW300x300) spaced 1.5 meters apart. A 20mm thick steel plate is placed on the platform 200 and precisely leveled. First longitudinal and transverse baselines are then laid out on the leveled platform 200. These baselines include a first longitudinal baseline and a first transverse baseline, which intersect at a single point. This platform 200 is specifically designed for the assembly of the steel anchor beam cable guide 400.

[0050] In one embodiment, the step of setting up the platform 200 on the hardened ground and arranging longitudinal and transverse reference lines on the platform 200 includes:

[0051] The flatness of the platform 200 was re-measured, and after passing the test, the first longitudinal and transverse baselines were laid out.

[0052] Specifically, after the platform 200 is set up, the flatness and level of the platform 200 are re-measured. After the inspection is qualified, the space cable guide 400 is assembled.

[0053] In step S102, according to the first longitudinal and transverse reference lines on the platform 200, a tooling structure 100 is arranged on the platform 200, and the tooling structure 100 is used for the assembly and positioning of the cable guide 400.

[0054] Specifically, after platform 200 is set up, tooling structure 100 is laid out according to the first longitudinal and transverse baselines on platform 200 for subsequent assembly and positioning of cable guide 400. For example... Figure 2 and Figure 3 As shown, the tooling structure 100 consists of an 8# channel steel 110, a DN40 seamless steel pipe 120, and a base plate 130 with a diameter of t=16mm. The tooling structure 100 is equipped with a lateral adjustment lifting device, which allows for the adjustment of the position of the cable guide 400.

[0055] The tooling structure 100 must meet the strength, rigidity, and stability requirements for positioning the cable guide 400, while also adhering to the principles of safety, reliability, and economic rationality. The platform 200, used in conjunction with the tooling structure 100, can more quickly adjust the dimensions of the high-precision control cable guide 400 to the correct position.

[0056] In step S103, a second longitudinal and transverse reference line 700 is laid out on the wall panel 300, and the steel bracket 800 is positioned according to the first longitudinal and transverse reference line on the platform 200 and the second longitudinal and transverse reference line 700 on the wall panel 300; wherein, the second longitudinal and transverse reference line 700 includes a second longitudinal reference line 710 and a second transverse reference line 720, and the second longitudinal reference line 710 and the second transverse reference line 720 intersect at a point.

[0057] Specifically, after the platform 200 and the working structure are set up, a second longitudinal and transverse reference line 700, a second longitudinal reference line 710, and a second transverse reference line 720 are set up on the wall panel 300. The second longitudinal reference line 710 and the second transverse reference line 720 intersect at a point. The steel bracket 800 is located based on the first longitudinal and transverse reference lines on the platform 200 and the second longitudinal and transverse reference lines 700 on the wall panel 300. That is, when the point where the first longitudinal reference line and the first transverse reference line intersect coincides with the point where the second longitudinal reference line 710 and the second transverse reference line 720 intersect, the steel bracket 800 can be located.

[0058] In step S104, the cable guide 400 is initially laid on the wall panel 300 by the tooling structure 100.

[0059] Specifically, after the platform 200, tooling structure 100, wall panel 300, and steel bracket 800 are arranged, the cable guide 400 is initially positioned on the wall panel 300 using the tooling structure 100. Since the wall panel 300 has an installation port 310 for the initial positioning and installation of the cable guide 400, when the cable guide 400 is initially positioned on the wall panel 300 using the tooling structure 100, it is essentially installing the cable guide 400 onto the installation port 310 using the tooling structure 100. The initial positioning and installation of the cable guide 400 can be achieved through the installation port 310 on the wall panel 300.

[0060] In step S105, the theoretical projection line of the cable guide 400 on the platform 200 is determined according to the preset transverse bridge axial angle, and a baseline plumb line is drawn at the intersection of the cable guide 400. The position of the cable guide 400 in the horizontal direction is adjusted by the tooling structure 100 so that the baseline plumb line intersects the theoretical projection line; wherein, the preset transverse bridge axial angle is the angle between the theoretical projection line and the first longitudinal reference line on the platform 200.

[0061] Specifically, a preset transverse bridge deflection angle is formed between the first longitudinal baseline on platform 200 and the theoretical projection line of cable guide 400 on platform 200. Therefore, the theoretical projection line of cable guide 400 on platform 200 can be determined by the preset transverse bridge deflection angle. After determining the theoretical projection line of cable guide 400 on platform 200, a baseline is suspended at the intersection on cable guide 400. The horizontal position of cable guide 400 is adjusted by tooling structure 100 so that the baseline is intersected with the theoretical projection line, thus completing the horizontal adjustment and positioning of cable guide 400.

[0062] The preset transverse bridge deflection angle can also be determined by the projection line of the cable conduit onto the wall panel at the return line 500 and the second longitudinal reference line 710 on the wall panel 300.

[0063] In step S106, the position of the cable guide 400 in the vertical direction is adjusted according to a preset angle so that the angle between the cable guide 400 and the wall panel 300 is within the angle error range of the preset angle.

[0064] Specifically, after adjusting the horizontal position of the cable guide 400, its vertical position also needs to be adjusted. The cable guide 400 and the wall panel 300 have a preset angle. Therefore, the vertical position of the cable guide 400 can be adjusted according to this preset angle so that the angle between the cable guide 400 and the wall panel 300 is within the preset angle error range, thus completing the vertical adjustment and positioning of the cable guide 400.

[0065] In one embodiment, the step of adjusting the vertical position of the cable guide 400 according to a preset angle so that the angle between the cable guide 400 and the wall panel 300 is within the angular error range of the preset angle includes:

[0066] Calculate the angle between the cable guide 400 and the wall panel 300, and verify the angle between the cable guide 400 and the wall panel 300. If the angle verification is successful, it proves that the angle between the cable guide 400 and the wall panel 300 is within the angle error range of the preset angle.

[0067] It should be noted that when adjusting the position of the cable guide 400 in the vertical direction according to the preset angle, the angle between the cable guide 400 and the wall panel 300 must be calculated first, and then the calculated angle between the cable guide 400 and the wall panel 300 must be verified. If the angle verification is successful, it means that the angle between the cable guide 400 and the wall panel 300 is within the angle error range of the preset angle, that is, the position adjustment of the cable guide 400 in the vertical direction is reasonable and the positioning is accurate.

[0068] In one embodiment, the step of calculating the angle between the cable conduit 400 and the wall panel 300 includes:

[0069] The length of the cable guide 400 itself is measured, the first vertical projection distance from the cable guide 400 to the wall panel 300 is measured, and the first horizontal projection distance from the cable guide 400 to the wall panel 300 is measured. A first triangle is formed by the length of the cable guide 400 itself, the first vertical projection distance, and the first horizontal projection distance. The angle between the cable guide 400 and the wall panel 300 is calculated by using trigonometric functions.

[0070] Specifically, such as Figure 4 and Figure 5 As shown, when calculating the angle between the cable guide 400 and the wall panel 300, it is necessary to measure the length of the cable guide 400 itself, the first vertical projection distance from the cable guide 400 to the wall panel 300, and the first horizontal projection distance from the cable guide 400 to the wall panel 300. These three measurements form a first triangle. After forming the first triangle, the angle between the cable guide 400 and the wall panel 300 is calculated using trigonometric functions. For example, if the first vertical projection distance from the cable guide 400 to the wall panel 300 is denoted as h1, the first horizontal projection distance as h2, and the angle between the cable guide 400 and the wall panel 300 as θ, then from tanθ=h1 / h2, we obtain θ=arctan(h1 / h2).

[0071] In one embodiment, the step of verifying the angle between the cable conduit 400 and the wall panel 300 includes:

[0072] By taking any point on the cable conduit 400, measuring the length of a segment of the cable conduit 400 from that point to the wall panel 300, measuring the second vertical projection distance of this segment of the cable conduit 400 to the wall panel 300, and measuring the second horizontal projection distance of this segment of the cable conduit 400 to the wall panel 300, a second triangle is constructed using the length of this segment of the cable conduit 400, the second vertical projection distance, and the second horizontal projection distance. The angle between this segment of the cable conduit 400 and the wall panel 300 is calculated using the triangle relationship.

[0073] Specifically, such as Figure 4 and Figure 5As shown, after calculating the angle θ between the cable guide 400 and the wall panel 300, further angle verification of the angle θ between the cable guide 400 and the wall panel 300 is required. When verifying the angle θ between the cable guide 400 and the wall panel 300, a point is randomly selected on the cable guide 400, and an auxiliary horizontal baseline 500 is drawn. The length of a segment of the cable guide 400 from this point to the wall panel 300 is measured. The second vertical projection distance of this segment of the cable guide 400 to the wall panel 300 is measured, as well as the second horizontal projection distance of this segment of the cable guide 400 to the wall panel 300, are then used to form a second triangle. After forming the second triangle, the angle between the segment of the cable guide 400 and the wall panel 300 is calculated using trigonometric functions. Let h3 be the second vertical projection distance from the cable conduit 400 to the wall panel 300, h4 be the second horizontal projection distance from the cable conduit 400 to the wall panel 300, and θ' be the angle between the cable conduit 400 and the wall panel 300. From tanθ'=h3 / h4, we can get θ'=arctan(h3 / h4).

[0074] It should be noted that the second triangle and the first triangle are similar triangles.

[0075] In one embodiment, the step of verifying the angle between the cable conduit 400 and the wall panel 300 includes:

[0076] If the angle between the cable guide 400 and the wall panel 300 is within the angle error range of the angle between the cable guide 400 and the wall panel 300, then it proves that the angle between the cable guide 400 and the wall panel 300 is within the angle error range of the preset angle.

[0077] Specifically, if the angle between the cable guide 400 and the wall panel 300 is within the angular error range of the angle between the cable guide 400 and the wall panel 300, then it proves that the angle between the cable guide 400 and the wall panel 300 is within the preset angular error range. In other words, if the angle θ' between the cable guide 400 and the wall panel 300 is within the angular error range of the angle θ between the cable guide 400 and the wall panel 300, then it proves that the angle between the cable guide 400 and the wall panel 300 is within the preset angular error range. This means that the vertical position of the cable guide 400 is reasonably adjusted and accurately positioned.

[0078] It should be noted that both the measurement error and the alignment accuracy error are less than or equal to 1 mm.

[0079] In one embodiment, the preset cross-bridge yaw angle is 1.615° to 7.954°.

[0080] Specifically, the preset range of the cross-bridge deflection angle is 1.615° to 7.954°, and can be 1.615°, 1.721°, 2.615°, 3.615°, 4.615°, 5.615°, 6.615° or 7.954°, etc. The specific value can be selected according to the actual situation, and this disclosure does not impose any restrictions on it.

[0081] In one embodiment, the preset angle is 26.011° to 58.636°.

[0082] Specifically, the preset angle ranges from 26.011° to 58.636°. It can be 26.011°, 28.013°, 30.051°, 40.631°, or 58.636°, etc., and can be selected according to the actual situation. This disclosure does not impose any restrictions on this.

[0083] In one embodiment, the angular errors of the preset transverse bridge deflection angle, the preset angle, the angle between the cable guide 400 and the wall panel 300, and the angle between the cable guide 400 and the wall panel 300 are all 0.1°.

[0084] Specifically, the preset transverse bridge deflection angle, preset angle, angle between the cable guide 400 and the wall panel 300, and angle between the cable guide 400 and the wall panel 300 can be allowed to have an angle error of 0.1°.

[0085] In one embodiment, the foundation bearing capacity of the platform 200 is greater than 150 kPa, the flatness f of the platform 200 is ≤ 2 mm, the layout accuracy of the first longitudinal and transverse baselines is guaranteed to be ≤ 0.5 mm, and the layout accuracy of the second longitudinal and transverse baselines 700 is guaranteed to be ≤ 0.5 mm.

[0086] Specifically, to ensure accuracy during assembly, the foundation of Platform 200 must have sufficient bearing capacity, and Platform 200 must have sufficient rigidity and meet assembly level requirements to avoid deformation during use. A bearing capacity greater than 150 kPa is sufficient for Platform 200.
