Description

Technical Field

[0001] This utility model relates to the field of bridge bearing technology, and in particular to a cable bearing. Background Technology

[0002] With economic development and increased investment in infrastructure construction, highway transportation and bridge engineering have seen tremendous growth. In bridge design, bearings, as key components, bear the load of the superstructure to the substructure and allow the superstructure to rotate and displace due to temperature changes or load effects. However, during an earthquake, excessive displacement of the superstructure may cause the bearings to collapse or even fall, rendering the bridge unusable and disrupting rescue and transportation routes.

[0003] To address the aforementioned issues, existing bridge designs often employ cable-stayed bearings. Cable-stayed bearings are based on ordinary pot bearings with the addition of cable assemblies (such as wire rope structures). These cable assemblies act as restraints during earthquakes, limiting the displacement of the bearing body within a controllable range, thereby effectively reducing the risk of excessive displacement of the superstructure and preventing beam collapse. However, in existing cable-stayed bearings, the cable assemblies are typically embedded in the upper and lower bearing plates of the bearing body for fixed installation. To meet the strength requirements for this embedded installation, the upper and lower bearing plates need to be thickened, which not only increases the material usage of the bearing but also significantly raises production costs. Furthermore, because the cable assemblies are embedded, replacement requires top-mounting operations, making the construction process complex and demanding on equipment and construction conditions, further increasing the difficulty and cost of replacement.

[0004] Therefore, there is an urgent need to propose a cable support to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cable support that makes the cable assembly easy to replace, saves material usage, and reduces production costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a cable support, including a support body and a cable assembly. The support body is used to support a beam, and the cable assembly is connected between the beam and the lower plate of the support body.

[0008] The cable assembly includes a steel cable, a first steel cable fixing assembly, and a second steel cable fixing assembly. The first end of the steel cable is fixed to the first steel cable fixing assembly, and the second end of the steel cable is fixed to the second steel cable fixing assembly. The first steel cable fixing assembly is detachably connected to the bottom surface of the beam, and the second steel cable fixing assembly is detachably connected to the outer surface of the lower seat plate.

[0009] In some embodiments, the first cable fixing assembly includes a fixing frame and a first fixing sleeve. The first fixing sleeve is disposed inside the fixing frame.

The mounting flange is connected to the bottom surface of the beam through the first fastener. The bottom of the fixing frame has a clearance hole through which the cable can pass. The cable can pass through the clearance hole and the inner hole of the first fixing sleeve. The first fixing sleeve is configured to clamp and fix the cable.

[0010] In some embodiments, the second cable fixing assembly includes a second fixing sleeve, which is connected to the lower base plate by a second fastener. The cable can pass through the inner hole of the second fixing sleeve and is clamped and fixed by the second fixing sleeve.

[0011] In some embodiments, the fixing frame is further provided with a fixing base and a buffer. The fixing base and the buffer are both sleeved on the outer periphery of the steel cable. The fixing base is disposed on the inner bottom wall of the fixing frame, and the buffer is disposed on the top of the fixing base and supports the first fixing sleeve.

[0012] In some embodiments, the steel cable is a steel wire rope; the first steel cable fixing assembly further includes a first steel wire rope clamp, which is disposed on the top of the first fixing sleeve and is sleeved and clamped to the outer periphery of the first end of the steel cable.

[0013] In some embodiments, the second cable fixing assembly further includes a second wire rope clamp, which is disposed at one end of the second fixing sleeve facing the lower seat plate, and the second wire rope clamp is sleeved and clamped to the outer periphery of the second end of the cable.

[0014] In some embodiments, the steel cable is a steel strand; the first steel cable fixing assembly further includes a first clamp, the first fixing sleeve is a conical fixing sleeve, and the inner diameter of the first fixing sleeve gradually decreases along the direction from the top of the fixing frame to the bottom of the fixing frame, and the first clamp is disposed on the inner wall of the first fixing sleeve and can clamp the steel cable.

[0015] In some embodiments, the second cable fixing assembly further includes a second clamping piece, the second fixing sleeve is a conical fixing sleeve, the inner diameter of the second fixing sleeve near the lower seat plate is larger than the inner diameter of the end away from the lower seat plate, and the second clamping piece is disposed on the inner wall of the second fixing sleeve and can clamp the cable.

[0016] In some embodiments, the lower base plate includes a mounting plate, and the second steel cable fixing assembly is detachably connected to the outer side of the mounting plate.

[0017] In some embodiments, the cable assemblies are provided in a plurality of locations, and the plurality of cable assemblies are spaced apart circumferentially along the support body.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] Example 1

[0039] like Figure 1 and Figure 2 As shown, this embodiment provides a cable support, including a support body 100 and a cable assembly 200. The support body 100 is used to support the beam 300, and the cable assembly 200 is connected between the beam 300 and the lower seat plate 110 of the support body 100.

[0040] like Figure 1 As shown, the bearing body 100 includes a lower bearing plate 110, a rubber pad 120, an intermediate steel liner 130, a flat sliding plate 140, a flat stainless steel plate 150, and an upper bearing plate 160. The beam 300 is disposed on the top surface of the upper bearing plate 160, and the lower bearing plate 110 is connected to the substructure of the bridge, such as a pier (not shown in the figure). The connection and function of the various components of the bearing body 100 are mature existing technologies in this field and will not be described in detail here.

[0041] The cable assembly 200 includes a steel cable 1, a first steel cable fixing assembly 2, and a second steel cable fixing assembly 3. The first end 11 of the steel cable 1 is fixed to the first steel cable fixing assembly 2, and the second end 12 of the steel cable 1 is fixed to the second steel cable fixing assembly 3. The first steel cable fixing assembly 2 is detachably connected to the bottom surface of the beam 300, and the second steel cable fixing assembly 3 is detachably connected to the outer surface of the lower seat plate 110.

[0042] The cable support provided in this embodiment, by adopting a detachable fixing design for the cable assembly 200, avoids the limitations of embedded installation. This eliminates the need for beam-mounting operations during the replacement of the cable assembly 200, significantly reducing construction complexity and equipment requirements, and improving the convenience of bridge maintenance. Furthermore, the second cable fixing component 3 of the cable assembly 200 is directly connected to the outer surface of the lower seat plate 110, eliminating the need for the traditional thickening of the lower seat plate 110 for embedded installation, effectively saving material. The first cable fixing component 2 is directly connected to the bottom surface of the beam 300, avoiding the increased thickness of the upper seat plate 160 caused by connection to it in traditional designs. This further reduces the overall thickness and weight of the support body 100, lowering production costs.

[0043] like Figure 1 As shown, in some embodiments, the lower base plate 110 includes a mounting plate 1101, and the second steel cable fixing assembly 3 is detachably connected to the outer side of the mounting plate 1101.

[0044] By setting a single mounting plate 1101, the second steel cable fixing component 3 can be directly connected to the outer side of the mounting plate 1101. In this way, only the design of the mounting plate 1101 needs to be increased locally, which can avoid thickening the entire lower seat plate 110 and significantly reduce the use of materials.

[0045] like Figure 2 As shown, in some embodiments, the first cable fixing assembly 2 includes a fixing frame 21 and a first fixing sleeve 22. The first fixing sleeve 22 is disposed inside the fixing frame 21. The top of the fixing frame 21 is provided with a radially outwardly protruding mounting flange 211. The mounting flange 211 has a mounting hole through which a first fastener can pass. The mounting flange 211 is connected to the bottom surface of the beam 300 by the first fastener. The bottom of the fixing frame 21 has a clearance hole for the cable 1 to pass through. The cable 1 can pass through the clearance hole and the inner hole of the first fixing sleeve 22. The first fixing sleeve 22 is configured to clamp and fix the cable 1.

[0046] By designing the first steel cable fixing assembly 2 as a structure including a fixing frame 21 and a first fixing sleeve 22, the first fixing sleeve 22 can tightly clamp the steel cable 1, and the fixing frame 21 is connected to the bottom surface of the beam 300 through the mounting flange 211, which facilitates the quick and stable connection of the first steel cable fixing assembly 2 to the beam 300, reduces construction time and labor costs, and provides a stable and reliable fixing solution for the steel cable 1.

[0047] Optionally, the first fastener may include, but is not limited to, a bolt.

[0048] like Figure 2 As shown, in some embodiments, the second cable fixing assembly 3 includes a second fixing sleeve 31, which is connected to the lower base plate 110 by a second fastener. The cable 1 can pass through the inner hole of the second fixing sleeve 31 and is clamped and fixed by the second fixing sleeve 31. This configuration makes the structure of the second cable fixing assembly 3 simpler, providing a simple and stable connection method.

[0049] Optionally, the second fastener may include, but is not limited to, a bolt.

[0050] Of course, in other embodiments, the second steel cable fixing component 3 can also be configured with the same structure as the aforementioned first steel cable fixing component 2, depending on the actual situation.

[0051] like Figure 2 As shown, in some embodiments, the fixing frame 21 is further provided with a fixing base 23 and a buffer member 24. Both the fixing base 23 and the buffer member 24 are sleeved on the outer periphery of the steel cable 1. The fixing base 23 is located on the inner bottom wall of the fixing frame 21, and the buffer member 24 is located on the top of the fixing base 23 and supports the first fixing sleeve 22. With this configuration, when an earthquake occurs, the buffer member 24 can achieve the function of buffering and dissipating energy through compression deformation, which plays a certain role in shock absorption and reduces the damage to the connection between the beam 300 and the cable support, as well as the cable assembly 200.

[0052] Optionally, the buffer 24 is made of buffer rubber. Due to the soft structure of the rubber, it can effectively prevent tension deviation and guide the steel cable 1, ensuring that the cable 1 is subjected to uniform force.

[0053] Optionally, multiple cable assemblies 200 are provided, with the multiple cable assemblies 200 spaced apart circumferentially along the support body 100. This allows the number of cable assemblies 200 to be reasonably set according to the actual seismic force on the bridge, to accommodate sufficient anti-falling beam capacity and buffering performance. For example, two or four cable assemblies 200 can be provided, depending on the specific circumstances.

[0054] like Figure 2As shown, in some embodiments, the steel cable 1 is a steel wire rope. The first steel cable fixing assembly 2 also includes a first steel wire rope clamp 25, which is disposed on the top of the first fixing sleeve 22 and is sleeved and clamped to the outer periphery of the first end 11 of the steel cable 1.

[0055] With this configuration, the first wire rope clamp 25 can further improve the fixing effect on the steel cable 1 based on the first fixing sleeve 22, and further enhance the overall stability of the cable assembly 200.

[0056] Furthermore, in some embodiments, the second cable fixing assembly 3 further includes a second wire rope clamp 32, which is disposed at one end of the second fixing sleeve 31 facing the lower seat plate 110, and is sleeved and clamped to the outer periphery of the second end 12 of the cable 1. With this arrangement, both the first cable fixing assembly 2 and the second cable fixing assembly 3 can maintain the cable 1 in a better fixed state.

[0057] Example 2

[0058] This embodiment provides a cable support, which is largely the same in structure as that of Embodiment 1. Therefore, only the differences between the two are described here. Structures identical to those in Embodiment 1 will not be repeated here. In this embodiment, the same or corresponding technical features as in Embodiment 1 are referred to by the same reference numerals.

[0059] like Figure 3 As shown, in this embodiment, the steel cable 1 is a steel strand. The first steel cable fixing assembly 2 also includes a first clamp 26 and a first fixing sleeve 22, which is a conical fixing sleeve. Along the direction from the top of the fixing frame 21 to the bottom of the fixing frame 21, the inner diameter of the first fixing sleeve 22 gradually decreases. The first clamp 26 is disposed on the inner wall of the first fixing sleeve 22 and can clamp the steel cable 1.

[0060] The tapered fixing sleeve is a common self-locking structure design that uses the force between the tapered interface and the steel strand to anchor the steel strand. The addition of the first clamping piece 26 further clamps the steel strand, effectively dispersing pressure and optimizing anchoring performance.

[0061] Furthermore, in some embodiments, the second cable fixing assembly 3 further includes a second clamping piece 33, and the second fixing sleeve 31 is a conical fixing sleeve. The inner diameter of the second fixing sleeve 31 at the end near the lower seat plate 110 is larger than the inner diameter at the end away from the lower seat plate 110. The second clamping piece 33 is disposed on the inner wall of the second fixing sleeve 31 and can clamp the cable 1. With this configuration, both the first cable fixing assembly 2 and the second cable fixing assembly 3 can enhance the anchoring performance of the cable 1.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
