Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a tower bridge anchoring structure. Background Art

[0002] Generally, on the steel anchor beam of a cable-stayed bridge with a straight tower, the constraint between the steel anchor beam and the steel corbel is mainly supported on the corbel steel wall plate through the end support of the steel anchor beam web, thereby transmitting the longitudinal unbalanced force of the cable to the bridge tower. However, for a curved concrete bridge tower, the anchor points of the steel anchor beam and the main beam are not on the same plane, so there will be a horizontal component of force on the steel anchor beam. In a curved bridge tower (such as an arched bridge tower), the cable also has a lateral unbalanced force transmitted to the steel anchor beam. During the construction stage of adjusting the cable force, the lateral unbalanced effect causes the steel anchor beam to slip laterally, causing the bolt holes between the steel anchor beam and the steel corbel to be misaligned, making it difficult to fix the steel anchor beam during the bridge completion stage.

It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0030] This embodiment provides a tower bridge anchoring structure, such as Figure 1 and Figure 2 As shown, it includes a steel anchor beam assembly 1, a corbel 2, an anchor head 3, an adjustment assembly 4 and a limit assembly 5;

[0031] The anchor head 3 is installed in the steel anchor beam assembly 1, the adjustment assembly 4 is connected to the end surface of the steel anchor beam assembly 1 and abuts against the anchor head 3, and the adjustment assembly 4 is used to adjust the position of the anchor head 3 relative to the steel anchor beam assembly 1;

[0032] The side walls at both ends of the steel anchor beam assembly 1 are connected to the limit assembly 5, and the side of the limit assembly 5 facing away from the steel anchor beam assembly 1 is used to abut against the external support to limit the lateral displacement of the steel anchor beam assembly 1;

[0033] The brackets 2 are connected to the bottoms of both ends of the steel anchor beam assembly 1 .

[0034] When the bridge is inclined, the steel anchor beam assembly 1 can be fixed at the corresponding position first, and the anchor head 3 can be placed in the steel anchor beam assembly 1. The position of the anchor head 3 relative to the steel anchor beam assembly 1 can be adjusted by the adjustment assembly 4, and then the pulling position of the cable 31 connected to the anchor head 3 can be fixed to complete the inclined operation. When the cable acts, the side of the limiting assembly 5 away from the steel anchor beam assembly 1 can be offset against the external support, effectively reducing the lateral movement of the steel anchor beam assembly 1 during construction. In addition, since the adjustment assembly 4 can adjust the position of the anchor head 3 in the steel anchor beam assembly 1, the performance and effect of the anchor head 3 and the cable 31 thereon on the steel anchor beam assembly 1 are improved.

[0035] In an optional embodiment, if Figure 3 As shown, the limiting assembly 5 includes a connecting plate 51, a buffer pad 52 and a limiting plate 53. One side of the connecting plate 51 is connected to the side wall of the end of the steel anchor beam assembly 1. The buffer pad 52 is connected between the side of the connecting plate 51 away from the steel anchor beam assembly 1 and the limiting plate 53. The limiting plate 53 is used to abut against an external support.

[0036] When the steel anchor beam assembly 1 has a tendency to move in the lateral direction, it will drive the limiting assembly 5 to move synchronously in the lateral direction. Since the limiting plate 53 can be abutted against the external support, the lateral movement of the steel anchor beam assembly 1 is limited, thereby ensuring the lateral position stability of the steel anchor beam assembly 1.

[0037] Since a buffer pad 52 is provided between the connection plate 51 and the limit plate 53 in the limit assembly 5, the buffer pad 52 can buffer the impact of the steel anchor beam assembly 1 on the concrete on both sides of the concrete bridge tower when it moves horizontally, thereby reducing the damage to the concrete on both sides of the concrete bridge tower.

[0038] Specifically, the buffer pad 52 may be a rubber pad.

[0039] The connecting plate 51 , the buffer pad 52 and the limiting plate 53 may be connected by fastening bolts or other fasteners, or may be connected by bonding or the like.

[0040] In an optional embodiment, if Figure 4 As shown, the adjustment component 4 includes an adjustment member 41 and a stop plate 42. The adjustment member 41 is connected to the end face of the steel anchor beam component 1. The stop plate 42 is slidably matched with the steel anchor beam component 1 along the extension direction of the steel anchor beam component 1. One end of the stop plate 42 is matched with the adjustment member 41 and slides relative to the steel anchor beam component 1 under the drive of the adjustment member 41, and the other end is abutted against the anchor head 3.

[0041] When using, Figure 4As shown, the adjusting member 41 can be used to drive the butt plate 42 to slide relative to the steel anchor beam assembly 1 along the extension direction of the steel anchor beam assembly 1, so that the butt plate 42 pushes the anchor head 3 to swing, thereby changing the action angle of the anchor head 3 in the steel anchor beam assembly 1 and improving the performance and effect of the anchor head 3 in the steel anchor beam assembly 1.

[0042] The anchor head 3 includes two legs 311 . The cable 31 passes through the space between the two legs 311 and through the through hole 121 . The abutment plate 42 is used to abut against the legs 311 above the cable 31 .

[0043] In an optional embodiment, if Figure 4 As shown, in order to make the structure of the adjusting member 41 simpler, the adjusting member 41 is threadedly connected to the end surface of the steel anchor beam assembly 1, and the rotation axis of the adjusting member 41 is parallel to the extension direction of the steel anchor beam assembly 1.

[0044] The user can rotate the adjusting member 41 to move the adjusting member 41 along the extension direction of the steel anchor beam assembly 1 , thereby driving the abutment plate 42 to slide relative to the steel anchor beam assembly 1 .

[0045] Specifically, the end of the adjusting member 41 can be abutted against the abutment plate 42, that is, the two can rotate relative to each other, so that when the adjusting member 41 is rotated, the abutment plate 42 can not rotate with it, but only move along the extension direction of the steel anchor beam assembly 1 under the push of the adjusting member 41.

[0046] In an optional embodiment, if Figure 4 As shown, both side walls of the steel anchor beam assembly 1 are provided with a slide groove 111, and the slide groove 111 and the abutment plate 42 are slidably matched along the extension direction of the steel anchor beam assembly 1 to ensure the stability of the abutment plate 42 when sliding.

[0047] The slide groove 111 may be a blind groove or a through groove.

[0048] Preferably, the slide groove 111 is a through groove.

[0049] In addition, the slide groove 111 may be a rectangular groove, or a waist-shaped groove, etc., and any shape that can guide the abutment plate 42 is acceptable.

[0050] Preferably, the slide groove 111 is a rectangular hole.

[0051] Specifically, both sides of the abutment plate 42 may be provided with limiting blocks 421 extending into the slide groove 111 and slidably matched with the slide groove 111 .

[0052] In order to facilitate the assembly of the abutment plate 42 and the steel anchor beam assembly 1, the limit block 421 can be detachably connected to the abutment plate 42, and the two can be connected by a locking bolt.

[0053] In an optional embodiment, if Figure 1 and Figure 4 As shown, the steel anchor beam assembly 1 includes a steel anchor beam body 11 and a connecting frame 12 connected to both ends of the steel anchor beam body 11, the connecting frame 12 is threadedly connected with an adjusting piece 41 and is provided with a through hole 121 for the upper cable 31 of the anchor head 3 to pass through, the two side walls of the steel anchor beam body 11 are provided with a sliding groove 111, and the ends of the two side walls are connected to the limiting assembly 5, and the bottom of the two ends of the steel anchor beam body 11 is installed with a bracket 2.

[0054] The connecting frame 12 connected to both ends of the steel anchor beam body 11 can play a role in strengthening the strength of the steel anchor beam assembly 1. Specifically, the connecting frame 12 can be welded to the ends of the steel anchor beam body 11.

[0055] The through hole 121 may be a rectangular hole or a waist-shaped hole, and any shape that can allow the cable 31 on the anchor head 3 to pass through is acceptable.

[0056] Preferably, the through hole 121 is a rectangular hole, and the through hole 121 extends vertically.

[0057] In an optional embodiment, if Figure 3 As shown, in order to facilitate the thrust of the adjusting member 41 acting on the abutment plate 42 to be directed directly to the support leg 311 above the anchor head 3 , the position where the connecting frame 12 is threadedly connected to the adjusting member 41 is higher than the position of the through hole 121 .

[0058] The corbel 2 may be connected only to the bottom surface of the steel anchor beam body 11 , or may be connected to both the steel anchor beam body 11 and the corbel 2 .

[0059] In an optional embodiment, if Figure 4 As shown, the bottom end of the connecting frame 12 protrudes from the bottom end of the steel anchor beam body 11 , and the corbel 2 is connected to the bottom surface of the steel anchor beam body 11 and the side surface of the connecting frame 12 protruding from the bottom end of the steel anchor beam body 11 .

[0060] It can be understood that the surface where the corbel 2 is connected to the steel anchor beam body 11 is perpendicular to the surface where the corbel 2 is connected to the connecting frame 12 .

[0061] The above arrangement can increase the connection area between the corbel 2 and the steel anchor beam assembly 1, thereby improving the installation strength of the steel anchor beam assembly 1.

[0062] Specifically, the corbel 2 can be welded to the bottom surface of the steel anchor beam body 11, or can be connected by bolts and nuts.

[0063] The bracket 2 can be welded to the side surface of the connecting frame 12 protruding from the bottom end of the steel anchor beam body 11, or can be connected by bolts and nuts.

[0064] The top end of the steel anchor beam body 11 is open, so that the steel anchor beam assembly 1 has better strength. Figure 1 As shown, the steel anchor beam assembly 1 further comprises a reinforcing plate 13 connected to the opening.

[0065] The reinforcement plate 13 can be welded to the steel anchor beam body 11 .

[0066] In an optional embodiment, along the extension direction of the steel anchor beam body 11 , the reinforcement plate 13 is located in the middle of the opening.

[0067] To facilitate the installation of the anchor head 3, Figure 1 As shown, along the extension direction of the steel anchor beam body 11, a first opening for the anchor head 3 to enter the steel anchor beam body 11 is formed between one end of the reinforcement plate 13 and the top end of the steel anchor beam body 11, and a second opening for the anchor head 3 to enter the steel anchor beam body 11 is formed between the other end of the reinforcement plate 13 and the top end of the steel anchor beam body 11.
