Description

Technical Field

[0001] This application relates to the field of cable tower construction technology, and in particular to a support structure for the closure section of a cable tower. Background Technology

[0002] Currently, the pylon structures in cable-stayed bridges generally adopt diamond, H, A-shape, and other similar shapes. Among them, diamond and A-shaped pylons both include a closure section, which is located at the top of the central tower column.

[0003] The concrete weight of the closure section reaches about 1,000 tons, requiring the design of a support structure to provide vertical support for the closure section. Furthermore, since the closure section presses on the top of the central tower column, it will cause the central tower column to tilt and deform inward, so horizontal support for the central tower column is also required.

[0004] Therefore, there is a need to provide a support structure that can reliably support the closure section of the tower. Utility Model Content

[0005] Therefore, it is necessary to provide a support structure for the closure section of the tower, and its specific technical solution is as follows.

[0006] A cable tower closure section support structure includes: The bracket includes a first side and a second side opposite to each other; the first side of the bracket is anchored to the inner wall of the central tower column; the inner walls of the two central tower columns are respectively anchored to the brackets, and the second sides of the two brackets are parallel to each other; The vertical support structure includes a vertical bracket and a load-bearing beam; the vertical bracket is supported below the bottom template of the closure section; the load-bearing beam is supported below the vertical bracket and rests on the corbel. A horizontal support structure includes a horizontal support member and a wedge-shaped member; the horizontal support member includes a first plate, a second plate, and a support rod; the support rod is connected to the first plate and the second plate respectively; the first plate includes a first surface away from the support rod, and the second plate includes a second surface away from the support rod; the first surface is parallel to and abuts against the second side of the bracket; the second surface is inclined relative to the first surface, and the wedge-shaped member is inserted between the second plate and the bracket.

[0007] Furthermore, the support rod includes a cut surface parallel to the second surface, and the second plate is welded to the cut surface.

[0008] Furthermore, the bottom of the cow leg is provided with a support plate, which extends outward toward the second side of the cow leg; the horizontal support member presses onto the support plate.

[0009] Furthermore, the corbel includes an anchor plate, a side plate, a transverse plate, and a longitudinal plate. The anchor plate is anchored to the inner wall of the central tower column by a pre-embedded climbing cone. The side plate is connected to the side of the anchor plate. The transverse plate and the longitudinal plate are respectively connected to the anchor plate and arranged crosswise to form a cavity.

[0010] Furthermore, a baffle is connected between the side plate and the support plate; the baffle extends outward to the second side of the bracket to limit the lateral displacement of the horizontal support.

[0011] Furthermore, a first stiffening plate is provided between the first plate and the support rod; a second stiffening plate is provided between the second plate and the support rod.

[0012] Furthermore, a working platform is provided below the corbel, and the working platform is anchored to the inner wall of the central tower column.

[0013] Furthermore, a discharging device is provided between the load-bearing beam and the corbel.

[0014] Furthermore, the wedge-shaped member includes a third surface parallel to the second side of the cow leg and a fourth surface parallel to the second surface of the second plate.

[0015] Furthermore, after the wedge is inserted between the second plate and the bracket and wedged tightly, the wedge is welded to the second plate.

[0016] Beneficial Effects: The cable tower closure section support structure provided by this utility model allows the vertical and horizontal support structures to share a set of brackets, providing vertical and horizontal support for the closure section and the central tower column. This prevents the central tower column from tilting inward, ensures the stability of the central tower column's alignment, eliminates secondary stresses caused by deformation, and simplifies the structure. By setting the second sides of the two brackets to be parallel to each other and setting the first and second plates to be relatively inclined, it is convenient to place the horizontal support members between the two brackets and then install wedges for tightening. No jacks or other equipment are needed to apply force, resulting in a simple structure, convenient operation, and low cost. Attached Figure Description

[0026] Example Reference Figure 1 and Figure 2As shown, this embodiment provides a support structure for the closure section of a cable tower, including corbels 1, vertical support structures 2, and horizontal support structures 3. There are two corbels 1, each anchored to the inner wall of one of the two central tower columns 4. Specifically, each corbel 1 includes a first side 11 and a second side 12 facing each other. The first side 11 of each corbel 1 is anchored to the inner wall of the central tower column 4; the second sides 12 of the two corbels 1 are parallel to each other, allowing the second sides 12 of each corbel 1 to be set vertically for easy installation of the horizontal support structure 3.

[0027] Specifically, continue to refer to Figure 2 As shown, the vertical support structure 2 includes a vertical bracket 21 and a load-bearing beam 22; the vertical bracket 21 is supported below the bottom template 23 of the closure section 5; the load-bearing beam 22 is supported below the vertical bracket 21 and presses against the corbel 1.

[0028] Specifically, continue to refer to Figure 2 As shown, the horizontal support structure 3 includes a horizontal support member 31 and a wedge-shaped member 32; the horizontal support member 31 includes a first plate 33, a second plate 35, and a support rod 37; the support rod 37 is connected to the first plate 33 and the second plate 35 respectively; the first plate 33 includes a first surface 34 away from the support rod 37, and the second plate 35 includes a second surface 36 away from the support rod 37; the first surface 34 is parallel to and abuts against the second side 12 of the corbel 1; the second surface 36 is inclined relative to the first surface 34, so that a gap larger at the top and smaller at the bottom is formed between the second surface 36 and the corbel 1, and the wedge-shaped member 32 is inserted between the second plate 35 and the corbel 1. Before the closure section 5 is poured, the horizontal support member 31 is placed between the two corbels 1, and the wedge-shaped member 32 is installed to wedge it tightly.

[0029] The cable tower closure section support structure provided in this embodiment allows the vertical support structure 2 and the horizontal support structure 3 to share a set of brackets 1, which can provide vertical and horizontal support for the closure section 5 and the central tower column 4, preventing the central tower column 4 from tilting inward, ensuring the linear stability of the central tower column 4, eliminating secondary stress caused by deformation, and making the structure simpler. By setting the second sides 12 of the two brackets 1 to be parallel to each other, and setting the first plate 33 and the second plate 35 to be relatively inclined, it is convenient to place the horizontal support 31 between the two brackets 1 and then install the wedge 32 for wedging, without the need to install jacks or other devices to apply force. The structure is simple, easy to operate, and low in cost.

[0030] Specifically, the support rod 37 includes a cut surface 39, which is parallel to the second surface 36, and the second plate 35 is welded to the cut surface 39. During the installation of the horizontal support structure 3, the support rod 37 is cut according to the measured distance between the two brackets 1, and then the second plate is welded to the support rod 37. The cast-in-place central tower column 4 will change with the ambient temperature; cutting the support rod 37 according to the measured distance can adapt to the actual spacing of the brackets 1. No constraints are applied to the central tower column 4 before the closure section 5 is cast, which prevents the generation of secondary stresses.

[0031] Specifically, the bottom of the bracket 1 is provided with a support plate 13, which extends outward toward the second side 12 of the bracket 1; the horizontal support member 31 is pressed onto the support plate 13. The horizontal support member 31 is directly placed on the support plate 13 for support, which facilitates installation.

[0032] Specifically, refer to Figure 4 and Figure 5 As shown, the corbel 1 includes an anchor plate 14, a side plate 15, a transverse plate 16, and a longitudinal plate 17. The anchor plate 14 is anchored to the inner wall of the central tower column 4 via a pre-embedded climbing cone 41. The side plate 15 is connected to the side of the anchor plate 14. The transverse plate 16 and the longitudinal plate 17 are respectively connected to the anchor plate 14 and arranged crosswise to form a cavity 18. The cavity 18 facilitates the connection between the pre-embedded climbing cone 41 and the anchor plate 14.

[0033] Specifically, a baffle 19 is connected between the side plate 15 and the support plate 13; the baffle 19 extends outward to the second side 12 of the bracket 1 to limit the lateral displacement of the horizontal support member 31. Lateral constraint is applied to the horizontal support member 31 to ensure its stability.

[0034] Specifically, a first stiffening plate 38 is provided between the first plate and the support rod 37; a second stiffening plate 38 is provided between the second plate and the support rod 37, and the stiffening plates 38 are connected by welding. The stiffening plates 38 improve the connection strength between the first plate 33, the second plate 35 and the support rod 37.

[0035] Specifically, a working platform 6 is provided below the corbel 1, and the working platform 6 is anchored to the inner wall of the central tower column 4. The working platform 6 facilitates the installation of the support structure.

[0036] Specifically, a dismantling device 24 is provided between the load-bearing beam 22 and the corbel 1. The dismantling device 24 is used to drive the vertical support structure 2 to move, thereby realizing the formwork 23's erection and demolding. The dismantling device 24 can be a jack or other forms of vertical telescopic structure.

[0037] Specifically, the wedge-shaped member 32 includes a third surface 321 parallel to the second side 12 of the bracket 1, and a fourth surface 322 parallel to the second surface 36 of the second plate 35. That is, the third plane and the fourth plane of the wedge-shaped member 32 are inclined relative to each other, so that the wedge-shaped member 32 is in a state where it is larger at the top and smaller at the bottom.

[0038] Specifically, after the wedge 32 is inserted between the second plate 35 and the bracket 1 and wedged tightly, the wedge 32 is welded to the second plate 35 to ensure the stability of the wedge 32.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
