Description

Technical Field

[0001] The present invention relates to the technical field of bridge engineering, and in particular to an attachment frame of a cable tower elevator and a construction method thereof. Background Art

[0002] A cable tower is a tower-shaped structure that supports the main cables of a suspension bridge or a cable-stayed bridge and is used to bear and transfer loads. Currently, common cable tower types include double-column cable tower structures. Most double-column cable tower structures have a connecting beam between the two tower columns. The connecting beam prevents the tower columns from deforming by connecting the two tower columns, thereby improving torsional and bending stiffness. In addition, in low-tower cable-stayed bridges, the connecting beam can share part of the load on the bridge deck. Therefore, the connecting beam is crucial to the double-column cable tower structure. During actual construction, in order to meet the load requirements of the cable tower, the tower columns usually have a certain inclination angle. Normally, the tower columns below the connecting beam will extend inward along the vertical downward direction to the ground foundation.

[0003] During cable tower construction, an elevator needs to be installed on one side of the tower column to transport workers and construction materials to a higher location. In the prior art, when installing the elevator, connectors (such as climbing cones, bolts, etc.) are usually pre-embedded in the tower column of the cable tower. Afterwards, the connectors only need to be connected to the guide rail frame of the elevator. The tower column below the connecting beam extends vertically downward and inward, while the guide rail frame of the elevator is in a vertical position. Therefore, for the tower column corresponding to the connecting beam and the tower column section below it, the horizontal distance between the guide rail frame and the tower column varies at different installation heights, resulting in different connector sizes at different installation heights. Therefore, it is necessary to customize connectors of various sizes according to different horizontal distances, which not only increases construction costs but also reduces construction efficiency and prolongs the construction period. Furthermore, after the cable tower construction is completed, the connectors need to be cut and removed, which may cause local heating in the area surrounding the pre-embedded connectors, resulting in microcracks or residual stress, thereby affecting the structural strength of the tower column and the connecting beam, and thus weakening the bearing capacity of the bridge. Summary of the Invention

[0004] The purpose of the present invention is to provide an attachment frame for a cable tower elevator and a construction method thereof, which can reduce construction costs, improve construction work efficiency, prevent the extension of the construction period, and avoid affecting the structural strength of the tower column and the connecting beam.

[0021] Beneficial effects of the present invention:

[0022] The present invention provides an attachment frame for a cable tower elevator and a construction method thereof. The attachment frame for the cable tower elevator includes a support rod and a connection assembly. When constructing a cable tower column, first, according to a preset construction position of the cable tower column and a preset position of the elevator, the lower end of the support rod is pre-buried in the foundation pedestal of the cable tower column, and the support rod is ensured to be located between the cable tower column and the elevator. The support rod extends vertically and the upper end is horizontally collinear with the cable tower connecting beam.

[0039] Example 1

[0040] This embodiment provides an attachment frame for a cable tower lift, such as Figures 1 to 4 As shown, it can not only reduce construction costs, improve construction efficiency, prevent the extension of construction period, but also avoid affecting the structural strength of the tower column and connecting beams.

[0041] like Figures 1 to 3 As shown, the attachment frame of the cable tower elevator includes a support rod 1 and a connection assembly 2. The lower end of the support rod 1 is configured to be embedded in the foundation pedestal of the cable tower column 200, and the support rod 1 is located between the cable tower column 200 and the elevator 100. The upper end of the support rod 1 is horizontally aligned with the connecting beam of the cable tower. The elevator 100 includes a vertically arranged guide rail frame 1001 and a cage 1002 that can move along the guide rail frame 1001. The connection assembly 2 includes multiple fixed frames 21 and multiple connecting frames 22. The multiple fixed frames 21 are axially spaced and sleeved on the support rod 1, and the fixed frames 21 are fixedly connected to the support rod 1. The multiple connecting frames 22 correspond to the multiple fixed frames 21. One end of the connecting frame 22 is detachably connected to the fixed frame 21, and the other end is detachably connected to the guide rail frame 1001.

[0042] When constructing the cable tower column 200, first, according to the preset construction position of the cable tower column 200 and the preset position of the elevator 100, the lower end of the support rod 1 is pre-buried in the foundation of the cable tower column 200, and the support rod 1 is ensured to be located between the cable tower column 200 and the elevator 100. The support rod 1 extends vertically and the upper end is horizontally collinear with the cable tower connecting beam. Therefore, it can be seen that the vertical height of the upper end of the support rod 1 is the same as the vertical height of the cable tower connecting beam. Moreover, at different vertical heights, the horizontal distance between the support pole 1 and the guide rail frame 1001 of the elevator 100 is the same. Then, multiple fixed frames 21 are axially spaced on the support pole 1, and the fixed frames 21 are fixedly connected to the support pole 1. Multiple connecting frames 22 are connected to the guide rail frame 1001 at intervals along the extension direction of the guide rail frame 1001, and the other ends of the multiple connecting frames 22 are connected one by one to the multiple fixed frames 21.

[0043] By providing the support uprights 1 and the fixed frame 21, the horizontal distance between the support uprights 1 and the guide rail frame 1001 of the elevator 100 is the same at different vertical heights. The two ends of the connecting frame 22 are respectively connected to the guide rail frame 1001 and the fixed frame 21 mounted on the support uprights 1. It is known that the size of the connecting frame 22 is consistent at different vertical heights, and there is no need to customize connecting frames 22 of various sizes, thereby reducing construction costs, improving construction efficiency, and preventing the extension of the construction period. At the same time, the fixed frame 21 can provide an installation foundation for the guide rail frame 1001. In addition, no pre-embedded connectors are included in the tower column 200 of this section (i.e., the tower column 200 below the tower connecting beam), which can avoid affecting the structural strength of the tower column and the connecting beam due to cutting and removing the pre-embedded connectors.

[0044] Alternatively, as Figures 1 to 3 As shown, the attachment frame of the cable tower elevator also includes a reinforcement connector 3. One end of the reinforcement connector 3 is fixedly connected to the support pole 1, and the other end is configured to be fixedly connected to the support frame 300 of the cable tower column 200. When the cable tower column 200 is being constructed, after the support pole 1 is pre-buried, the reinforcement connector 3 can be connected between the support pole 1 and the support frame 300 of the cable tower column 200. By providing the reinforcement connector 3, the lateral stability of the support pole 1 can be enhanced, the shaking of the support pole 1 can be reduced, the lateral displacement resistance and bending resistance of the support pole 1 can be improved, and the installation stability of the guide frame 1001 can be guaranteed, thereby ensuring the normal operation of the elevator 100. At the same time, the load of the support pole 1 can be transferred to the support frame 300, which is beneficial to the overall stability of the structure.

[0045] It should be noted that the number of the reinforcing connectors 3 can be one, two, or more than two, which is not limited here. The installation position of the reinforcing connector 3 is determined according to the actual construction situation. In this embodiment, there is one reinforcing connector 3, which is installed at the upper end of the support pole 1.

[0046] Alternatively, as Figure 1 、 Figure 2 and Figure 4 As shown, the reinforcement connector 3 includes two first connection rods 31. The two first connection rods 31 are arranged on both sides of the support upright 1 along the radial direction of the support upright 1. One end of the first connection rod 31 is fixedly connected to the support upright 1, and the other end is fixedly connected to the support frame 300. By providing two first connection rods 31, the support upright 1 can be reinforced and supported along both sides of the radial direction of the support upright 1, forming a symmetrical reinforcement support, which can effectively resist horizontal forces from any direction, avoid the force imbalance caused by unilateral reinforcement support, and at the same time form a bilateral constraint on the support upright 1, significantly improving the bending resistance of the support upright 1.

[0047] Alternatively, as Figure 1 、 Figure 2 and Figure 4 As shown, the reinforcement connector 3 further includes a plurality of reinforcement rods 32. The plurality of reinforcement rods 32 are spaced apart along the extension direction of the first connection rods 31, with the ends of the reinforcement rods 32 fixedly connected to the two first connection rods 31. The plurality of reinforcement rods 32 and the two first connection rods 31 form a spatial truss structure, further enhancing the reinforcement and support effect of the reinforcement connector 3 on the support poles 1 and significantly increasing the overall rigidity and stability of the attachment frame.

[0048] Exemplarily, there are provided five reinforcement rods 32. In other embodiments, two, two to four, or five or more reinforcement rods 32 may be provided according to actual needs, which is not limited here.

[0049] Alternatively, as Figures 1 to 3 As shown, the cable tower lift's attachment frame also includes a connector 5 and fasteners. A lap joint 4 is provided on the side of the connecting frame 22 facing away from the guide rail frame 1001. The lap joint 4 overlaps the fixed frame 21. The connector 5 passes through the fixed frame 21 and the lap joint 4 and is threadedly connected to the fasteners. To connect the fixed frame 21 and the connecting frame 22, simply overlap the lap joint 4 with the fixed frame 21. Afterwards, the connector 5 passes through the fixed frame 21 and the lap joint 4 overlapped with the fixed frame 21 and is threadedly connected to the fasteners. This results in a simple structure, easy operation, and convenient disassembly and installation.

[0050] It should be noted that the bridge piece 4 and the connecting frame body 22 are connected into one piece by welding.

[0051] Illustratively, bridging member 4 comprises a steel plate.

[0052] In this embodiment, the fixed frame 21 comprises four channel steels, which are arranged around the support upright 1 and connected end to end. When connecting the fixed frame 21 to the connecting frame, the lap joint 4 is stacked on a channel steel facing the connecting frame 22. Then, the plug-in connector 5 is simply inserted through the lap joint 4 and the stacked channel steel, and threadedly connected to the fastener.

[0053] Exemplarily, the connector 5 includes a bolt, and the fastener includes a fastening nut.

[0054] Optionally, the attachment frame of the cable tower lift also includes a stopper plug and a stopper fixture. A connecting lug is provided on the side of the connecting frame 22 facing the guide rail frame 1001. The connecting lug is attached to the side wall of the guide rail frame 1001. The stopper plug extends through the connecting lug and the guide rail frame 1001. A tightening boss is provided at the end of the stopper plug, which presses against the connecting lug. A stopper socket is defined on the end of the stopper plug facing away from the connecting lug. The stopper fixture is inserted into the stopper socket and presses against the guide rail frame 1001.

[0055] When connecting the guide rail frame 1001 and the connecting frame 22, it is necessary to attach the connecting ear plate to the side wall of the guide rail frame 1001, and then pass the limiting plug-in through the connecting ear plate and the guide rail frame 1001, so that the tightening boss and the connecting ear plate are tightened against each other, and then pass the limiting fixing piece through the limiting socket, so that the limiting fixing piece and the guide rail frame 1001 are tightened against each other. The structure is simple, the operation is convenient, and it is easy to disassemble and install.

[0056] Exemplarily, the limiting plug-in includes a pin shaft, and the limiting fixing member includes a safety fixing pin.

[0057] Example 2

[0058] This embodiment provides a method for constructing an attachment frame of a cable tower lift, using the attachment frame of the cable tower lift described in Example 1. The method for constructing the attachment frame of the cable tower lift includes the following steps:

[0062] By providing the support uprights 1 and the fixed frame 21, the horizontal distance between the support uprights 1 and the guide rail frame 1001 of the elevator 100 is the same at different vertical heights. The two ends of the connecting frame 22 are respectively connected to the guide rail frame 1001 and the fixed frame 21 mounted on the support uprights 1. It is known that the size of the connecting frame 22 is consistent at different vertical heights, and there is no need to customize connecting frames 22 of various sizes, thereby reducing construction costs, improving construction efficiency, and preventing the extension of the construction period. At the same time, the fixed frame 21 can provide an installation foundation for the guide rail frame 1001. In addition, no pre-embedded connectors are included in the tower column 200 of this section (i.e., the tower column 200 below the tower connecting beam), which can avoid affecting the structural strength of the tower column and the connecting beam due to cutting and removing the pre-embedded connectors.

[0063] Optionally, a reinforcement connector 3 is provided between the support pole 1 and the support frame 300 of the tower column 200. Step S20 is performed after step S1 is performed and before step S2 is performed. Step S20 specifically includes:

[0064] One end of the reinforcement connector 3 is fixedly connected to the support pole 1 , and the other end is fixedly connected to the support frame 300 of the tower column 200 .

[0065] By setting up the reinforcing connector 3, the lateral stability of the supporting pole 1 can be enhanced, the shaking of the supporting pole 1 can be reduced, the anti-lateral displacement and anti-bending capabilities of the supporting pole 1 can be improved, and the installation stability of the guide rail frame 1001 can be ensured, thereby ensuring the normal operation of the elevator 100. At the same time, the load of the supporting pole 1 can also be transferred to the supporting frame 300, which is beneficial to the overall stability of the structure.
