Description

Technical Field

[0001] The present application relates to the technical field of suspension bridge construction, and in particular to a transverse wind-resistant bearing construction structure for a super-large bridge and an installation method thereof. Background Art

[0002] A suspension bridge, also known as a suspension bridge, refers to a bridge with cables suspended from towers and anchored on both sides as the main load-bearing components of the upper structure. The geometric shape of the cables is determined by the balance of forces and is generally close to a parabola. Many hangers are hung from the cables to suspend the bridge deck. Stiffening beams are often set between the bridge deck and the hangers to form a combined system with the cables to reduce the deflection caused by the load.

[0003] The deck of a suspension bridge is generally supported by the transverse braces of the cable towers, that is, the steel frame of the bridge deck is directly located on the transverse braces of the cable towers. In order to prevent the steel frame from shifting along the lateral transition, transverse wind-resistant bearings are generally used to limit the steel frame. The part where the existing transverse wind-resistant bearings are connected to the cable towers is generally pre-buried directly on the pad stones of the cable towers. However, the pre-buried method easily causes the angle accuracy of the transverse wind-resistant bearings to be low, affecting the service life of the transverse wind-resistant bearings.

[0031] Embodiment 1 A construction structure of a transverse wind-resistant support for a super-large bridge, referring to Figures 1 to 4, including a cushion stone 1, a first connecting steel plate 2, a second connecting steel plate 3 and a support bolt 21, and a reserved bolt hole 11 is provided on the cushion stone 1. A leveling space is reserved between the first connecting steel plate 2 and the cushion stone 1, and the leveling space is used to pour concrete to form a leveling layer 5. The support bolt 21 is threadedly connected to the first connecting steel plate 2, and is inserted into the reserved bolt hole 11 to be connected to the cushion stone 1. The second connecting steel plate 3 is fixedly connected to the steel frame, and a shock absorbing component 4 is connected between the first connecting steel plate 2 and the second connecting steel plate 3, and the shock absorbing component 4 can be a rubber pad. When pouring the cushion stone 1, the reserved bolt hole 11 is first reserved to facilitate the connection with the first connecting steel plate 2, and a leveling space is set between the first connecting steel plate 2 and the cushion stone 1. After the angle adjustment of the first connecting steel plate 2 is completed, the leveling layer 5 is poured to form. While ensuring the accuracy of the first connecting steel plate 2, the connection strength between the first connecting steel plate 2 and the cushion stone 1 is guaranteed.

[0032] Specifically, the thickness of the leveling layer 5 may be 3 cm. The 3 cm leveling layer 5 can provide the first connecting steel plate 2 with enough space to adjust the angle, while ensuring the connection strength between the first connecting steel plate 2 and the cushion stone 1 .

[0033] In addition, a concrete column 12 is formed in the reserved bolt hole 11 to relatively fix the support bolt 21 and the cushion stone 1, and the connection strength between the support bolt 21 and the cushion stone 1 is improved by casting.

[0034] An installation method, based on the above-mentioned super-large bridge transverse wind-resistant bearing construction structure, comprises the following steps: S1, pouring pad stone 1, with reserved bolt holes 11 reserved during pouring.

[0035] S2. Fix the first connecting steel plate 2 by auxiliary tooling, and reserve a leveling space between the first connecting steel plate 2 and the cushion stone 1.

[0036] S3. Install the support bolt 21 on the first connecting steel plate 2 and allow the head of the support bolt 21 to extend into the reserved bolt hole 11.

[0037] S4. Pour concrete into the leveling space to form the leveling layer 5 and fix the support bolts 21 and the cushion stone 1 relatively.

[0038] When pouring the pad stone 1, a reserved bolt hole 11 is first reserved to facilitate connection with the first connecting steel plate 2. At the same time, a leveling space is set between the first connecting steel plate 2 and the pad stone 1. After the angle adjustment of the first connecting steel plate 2 is completed, a leveling layer 5 is poured to form. While ensuring the accuracy of the first connecting steel plate 2, the connection strength between the first connecting steel plate 2 and the pad stone 1 is guaranteed.

[0039] The auxiliary tooling includes a frame 6, a steel plate positioning assembly 61, a template assembly 62 and a vibration assembly 63. The steel plate positioning assembly 61 and the template assembly 62 are both arranged on the frame 6. The steel plate positioning assembly 61 is used to connect with the first connecting steel plate 2 to limit the position of the first connecting steel plate 2; the template assembly 62 is used to abut against the pad stone 1 and the first connecting steel plate 2 to close the bottom and side surfaces of the leveling space. The first connecting steel plate 2 is positioned by the steel plate positioning assembly 61, and the leveling space is conveniently poured by the template assembly 62. The steel plate positioning assembly 61 and the template assembly 62 are arranged on the same frame 6, which can ensure the pouring accuracy. At the same time, the concrete in the leveling space is vibrated by the vibration assembly 63 to ensure the uniformity of the leveling layer 5, thereby ensuring the pressure-bearing performance of the leveling layer 5.

[0040] Specifically, the steel plate positioning assembly 61 includes a connecting frame 611 and a positioning plate 612. The connecting frame 611 is fixedly connected to the frame 6. The positioning plate 612 is fixedly connected to the connecting frame 611. There are four positioning plates 612. The four positioning plates 612 are all in contact with one end of the first connecting steel plate 2 away from the pad stone 1. Each positioning plate 612 is provided with a positioning bolt 613. The positioning bolt 613 passes through the positioning plate 612 and is threadedly connected to the first connecting steel plate 2. The first connecting steel plate 2 is provided with a threaded hole for connecting with the shock absorbing assembly 4, which can be used to connect with the positioning bolt 613. Through the cooperation of the positioning bolt 613 and the positioning plate 612, the first connecting steel plate 2 is locked to ensure the stability when pouring the leveling layer 5. A gasket is provided between the positioning plate 612 and the first connecting steel plate 2. The number of gaskets can be adjusted to control the angle of the first connecting steel plate 2 to achieve the leveling of the first connecting steel plate 2. The angle of the first connecting plate is adjusted by controlling the number of gaskets, which is more reliable and can be maintained for a long time.

[0041] The template assembly 62 includes a bottom mold 622 and two side molds 621. The bottom mold 622 is connected to the frame 6 via a vertical moving assembly 623, and the side mold 621 is connected to the frame 6 via a horizontal moving assembly 624. The bottom mold 622 and the side molds 621 are both in contact with the side of the pad stone 1 facing the first connecting steel plate 2. The bottom mold 622 is in contact with the bottom surface of the first connecting steel plate 2, and the two side molds 621 are respectively in contact with the two side surfaces of the first connecting steel plate 2. The vertical moving assembly 623 is used to drive the bottom mold 622 to move in the vertical direction, and the horizontal moving assembly 624 is used to drive the side mold 621 to move in the horizontal direction. The vertical moving component 623 has the same structure as the horizontal moving component 624, so the vertical moving component 623 is taken as an example for explanation here. The vertical moving component 623 includes a screw 6231, a guide rod 6232 and a handle 6233. The screw 6231 is rotatably connected to the connecting frame 611, and the screw 6231 is threadedly connected to the bottom mold 622. The guide rod 6232 is fixedly connected to the connecting frame 611, and the guide rod 6232 passes through the bottom mold 622. The handle 6233 is coaxially fixed with the screw 6231, and the handle 6233 can be rotated to adjust the position of the bottom mold 622.

[0042] It should be noted that the bottom of the bottom mold 622 is fixedly connected with a vertical plate 6221 , and the vertical plate 6221 is fixedly connected to the cushion stone 1 through expansion bolts, thereby ensuring the stability of the bottom mold 622 .

[0043] The vibration assembly 63 includes a vibration frame 631 and a vibration motor 632. The vibration motor 632 is attached to the side of the first connecting steel plate 2 away from the pad stone 1, and the vibration frame 631 does not contact the frame 6, thereby reducing the influence of the vibration motor 632 on the side mold 621 and the bottom mold 622. The first connecting steel plate 2 is vibrated by the vibration motor 632, thereby ensuring the vibration effect, ensuring the uniformity of the leveling layer 5, and then ensuring the compressive strength. Because the lateral wind-resistant support mainly bears pressure and has a relatively small requirement for tensile resistance, it is sufficient to mainly ensure the strength of the leveling layer 5, and the requirement for the concrete column 12 is relatively low.

[0044] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
