Description

Technical Field

[0001] This utility model belongs to the field of suspension bridge technology, specifically an anchorage component for suspension bridges. Background Technology

[0002] In modern bridge construction, suspension bridges occupy an important position due to their unique structure and spanning capacity. Ground-anchored suspension bridges, as a widely used type, rely heavily on the anchorage assembly, one of their main load-bearing structures, for stability. The anchorage assembly consists of an anchor 1 and multiple pads 2. The main cable passes through the anchor 1 and pads 2 of the anchorage assembly via cable strands and is then secured to the rear anchor face.

[0003] like Figure 1 — Figure 6 As shown, the anchor 1 has multiple strand through holes 11 for the main cable strands to pass through; the strand through holes 11 penetrate the upper and lower ends of the anchor 1. The number of pad blocks 2 is the same as the number of strand through holes 11; the pad blocks 2 and the anchor 1 are generally connected by welding. The pad block 2 has pad through holes 21 with the same diameter as the strand through holes 11, and the pad through holes 21 correspond to the strand through holes 11. The pad through holes 21 penetrate the upper and lower ends of the pad block 2. The upper end of the pad block 2 is a slope (anchoring surface), and the lower end of the pad block 2 is a plane, with the outer circumferential surface of the pad block 2 perpendicular to the plane at the lower end. The slope (anchoring surface) at the upper end of the pad block 2 needs to be installed according to requirements, therefore, markings will be made at specific positions on the pad block 2. The existing method is to mark the thinnest and thickest points of the existing circular pad block 202; and the four corners of the existing square pad block 203.

[0004] In practice, the following problems exist during the installation process of mounting the pad 2 onto the anchor 1.

[0005] First, during the welding of the pad block 2 to the anchor 1, the complexity and uncertainty of the welding process can easily lead to deviations in the welding position, and even situations where the pad block 2 is welded in the wrong direction. These problems not only affect the efficiency and quality of installation, but may also pose a potential threat to the overall structural stability and safety of the suspension bridge.

[0006] Second, since the angle of each cable strand through hole 11 on the anchor 1 is different, when the joint surface of the anchor 1 and the pad block 2 is marked in the factory, it is easily affected by a variety of factors, such as measurement error and processing accuracy, which will cause the marking to deviate.

[0007] Therefore, existing installation methods place high demands on factory processing technology and the technical skills of on-site construction personnel. If problems arise during factory marking or welding, it becomes difficult to make effective corrections on-site, thus increasing construction and time costs. Summary of the Invention

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figure 1 — Figure 11 As shown, an anchorage assembly for a suspension bridge includes an anchorage 1 with multiple strand through holes 11 for the main cable strands to pass through; a pad block 2 with a pad through hole 21 of the same diameter as the strand through holes 11, and the pad through holes 21 corresponding to the strand through holes 11; the pad block 2 and the anchorage 1 are detachably connected by screws; both the anchorage 1 and the pad block 2 are marked with mutually matching symbols that can distinguish the installation direction. By using a detachable connection between the pad block 2 and the anchorage 1 with screws, errors in the installation of the pad block 2 can be corrected on-site. Furthermore, to facilitate the identification of the installation direction, mutually matching symbols on both the anchorage 1 and the pad block 2 allow for quick determination of the installation direction during installation, reducing construction and time costs. This technical measure has the advantages of simple structure, easy on-site correction, and reduced construction and time costs.

[0026] like Figure 6 — Figure 9 As shown, in specific implementation, multiple connecting screw holes 12 are evenly distributed along the outer edge of the cable strand through hole 11 of the anchor 1; multiple connecting holes 22 penetrating the upper and lower ends of the pad 2 are provided along the outer edge of the pad through hole 21 of the pad 2; the connecting holes 22 correspond to the connecting screw holes 12; the connecting holes 22 and the connecting screw holes 12 are connected by locking screws 3. By providing connecting screw holes 12 on the anchor 1 and connecting holes 22 on the pad 2, the pad 2 is detachably fixed to the anchor 1 by locking screws 3; if an installation error occurs, it can be corrected on-site. This technical measure has the advantages of simple structure, easy on-site correction, and reduced construction and time costs.

[0027] like Figure 8 As shown, the anchor 1 is generally square in structure, and has multiple strand through holes 11 for the main cable strands to pass through. Multiple connecting screw holes 12 are evenly distributed along the outer edge of the strand through holes 11 of the anchor 1. In actual use, at least two connecting screw holes 12 are used. The pad 2 has a pad through hole 21 with the same diameter as the strand through holes 11. The pad through hole 21 extends through both the upper and lower ends of the pad 2. The upper end of the pad 2 is inclined, and the lower end of the pad 2 is flat. The outer circumferential surface of the pad 2 is perpendicular to the lower flat surface. The pad 2 is square or circular in shape.

[0028] like Figure 8As shown, the connecting screw holes 12 are two symmetrically arranged on the outer edge of the cable strand through hole 11, and the two connecting screw holes 12 correspond to the two ends of the diameter of the cable strand through hole 11; the connecting holes 22 are two symmetrically arranged on the outer edge of the pad through hole 21, and the two connecting holes 22 correspond to the two ends of the diameter of the pad through hole 21 and are set with respect to the connecting screw holes 12. In actual use, since the pad through hole 21 and the cable strand through hole 11 have the same diameter, the pad through hole 21 and the cable strand through hole 11 are set correspondingly during installation; accordingly, the number and arrangement of the connecting holes 22 correspond to the connecting screw holes 12. Specifically, the two connecting screw holes 12 are arranged symmetrically along the radial, longitudinal or radially inclined direction of the anchor 1 on the outer edge of the cable strand through hole 11 according to actual needs, and the two connecting screw holes 12 correspond to the two ends of the diameter of the cable strand through hole 11. The connecting holes 22 are two symmetrically arranged on the outer edge of the through hole 21 of the pad block. The two connecting holes 22 correspond to the two ends of the diameter of the through hole 21 of the pad block and are set with the connecting screw holes 12. This technical solution facilitates quick positioning and quick installation.

[0029] like Figure 7 , Figure 9 , Figure 10 , Figure 11 As shown, the upper surface of the pad 2 is inclined; the two connecting holes 22 are respectively a first connecting hole with an opening at a high position on the upper surface of the pad 2 and a second connecting hole with an opening at a low position on the upper surface of the pad 2; during installation, when the first connecting hole mates with one of the connecting screw holes 12, the second connecting hole mates with the other connecting screw hole 12. In specific implementation, the upper surface of the pad 2 is generally inclined, and its cross-section is a trapezoid with the inclined side at the top. To facilitate installation after quickly confirming the orientation, the two connecting holes 22 are respectively located at a high position on the upper surface of the pad 2 and at a low position on the upper surface of the pad 2.

[0030] like Figure 6 , Figure 8 , Figure 9As shown, the markings include anchor markings 13 on anchor 1 and pad markings 23 on pad 2. Anchor markings 13 include a first anchor marking and a second anchor marking at the upper end face of anchor 1 at the outer edge of cable through hole 11, and at both ends corresponding to the diameter of cable through hole 11. Pad markings 23 include a first pad marking and a second pad marking on the upper end face of pad 2 that match the first and second anchor markings. In specific implementation, anchor markings 13 specifying the subsequent installation orientation of pad 2 are pre-marked / drawn on anchor 1 as needed. Pad 2 is pre-marked / drawn during manufacturing to match the anchor markings 13 on anchor 1 and to distinguish the installation direction. This technical measure makes it easy to confirm whether there is a problem with the installation direction of the pad 2. At the same time, once an installation error of the pad 2 is found, the direction of the pad 2 can be readjusted or the pad 2 can be replaced on site according to the markings, so as to achieve effective correction on site and reduce construction costs and time costs.

[0031] In practical use, there is a structure with three or four connecting screw holes 12 evenly distributed in a ring around the outer edge of the cable through hole 11, and correspondingly, there are also three or four connecting holes 22. By setting the first anchor mark and the second anchor mark at the outer edge of the cable through hole 11, and setting the first pad mark and the second pad mark on the upper end face of the pad 2, workers can quickly position and install the equipment on site, effectively improving work efficiency.

[0032] like Figure 9 , Figure 10 , Figure 11 As shown, in specific implementation, the anchor mark 13 is a number, text or letter; correspondingly, the pad mark 23 is a number, text or letter.

[0033] like Figures 8-10 As shown, in this embodiment, when the anchor mark 13 is a number, the corresponding pad mark 23 is also a number. The upper end face of the anchor 1 at the outer edge of the cable through hole 11, and at both ends corresponding to the diameter of the cable through hole 11, are provided with a first anchor mark of the number "1" and a second anchor mark of the number "2". Correspondingly, the upper end face of the pad 2 is provided with a first pad mark of the number "1" and a second pad mark of the number "2" that match the first and second anchor marks. In actual use, when the first anchor mark is the number "1", the second anchor mark is the number "2". Here, the first and second anchor marks are not the same, and the direction can be determined. Specifically, when the number "1" represents forward, the number "2" represents backward, or when the number "2" represents forward, the number "1" represents backward. The numbers “1” and “2” mentioned above can also be represented by A and B.

[0034] When the anchor mark 13 is text, the corresponding pad mark 23 is also text. Specifically, the upper end face of the anchor 1 at the outer edge of the cable through hole 11, and at both ends corresponding to the diameter of the cable through hole 11, are provided with a first anchor mark with the text "front" and a second anchor mark with the text "rear"; correspondingly, the upper end face of the pad 2 is provided with a first pad mark with the text "front" and a second pad mark with the text "rear" that match the first and second anchor marks. This technical measure further ensures that the installation direction can be quickly determined, reducing construction and time costs. This technical measure has the advantages of simple structure, on-site correction capability, and reduced construction and time costs.

[0035] like Figure 9 , Figure 10 , Figure 11 As shown, when the first anchor mark is located near one of the two connecting bolt holes 12, the second anchor mark is located near the other connecting bolt hole 12; correspondingly, when the first pad mark is located near one of the two connecting holes 22, the second pad mark is located near the other connecting hole 22. This technical measure allows for faster determination of the installation orientation, reducing construction and time costs.

[0036] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
