Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and relates to the construction of cable towers for cable-stayed bridges or suspension bridges, specifically to a cable tower decorative panel structure that also serves as a load-bearing support. Background Technology

[0002] The pylons of cable-stayed or suspension bridges are often designed in A-shape, V-shape, diamond shape, etc. Figure 1 As shown, the tower type includes two relatively inclined tower legs 100, which intersect at their upper ends, with a crossbeam 101 installed at the intersection. To make the tower's lines smoother and more aesthetically pleasing, decorative panels 1 in the form of arches, parabolic curves, or arcs are often installed between the bottom of the crossbeam and the inner walls of the two tower legs. The decorative panels 1 are usually made of steel plates and are installed after the crossbeam is constructed. The construction of the crossbeam requires the erection of high-altitude scaffolding or supports, which are then dismantled after construction, resulting in a long construction period and high material consumption. Summary of the Invention

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a cable tower decorative panel structure that can also serve as a load-bearing support for the construction of the upper crossbeam, thereby simplifying the process and saving costs.

[0004] This utility model provides a cable tower decorative panel structure that also serves as a load-bearing support, characterized in that it includes a decorative panel, embedded steel plates, and load-bearing plates; the decorative panel is arched or parabolic in shape and is set between two tower legs, with the embedded steel plates embedded in the concrete inside the two tower legs respectively; the load-bearing plates are horizontally set above the decorative panel, with the lower ends of both sides of the decorative panel welded to the lower ends of the embedded steel plates on the two towers respectively, and the two ends of the load-bearing plates welded to the upper ends of the two embedded steel plates respectively; multiple vertical support plates are welded between the bottom surface of the load-bearing plates and the decorative panel, and multiple horizontal stiffening plates are welded between the decorative panel and the embedded steel plates on both sides respectively.

[0005] The decorative panel structure of this utility model has a strong load-bearing capacity. The cable tower decorative panel is installed before the upper crossbeam is constructed, and its own structural characteristics are used as a load-bearing support for the construction of the crossbeam at the cable tower intersection section. There is no need to erect a special high-altitude support, which can significantly reduce the construction difficulty and cost of the crossbeam and improve construction efficiency. The load-bearing plate of the decorative panel structure of this utility model serves as the bottom formwork when the upper crossbeam is poured. After the upper crossbeam is poured, the load-bearing plate is not removed. It is integrated with the upper crossbeam concrete and serves as part of the permanent structure of the upper crossbeam, which can improve the structural strength of the upper crossbeam.

[0011] like Figure 2 As shown, the present invention provides a cable tower decorative panel structure that also serves as a load-bearing support, comprising a decorative panel 1, embedded steel plates 2, and load-bearing plates 3; the decorative panel 1 is arched or parabolic in shape and is set between two tower legs 100 of the cable tower, with the embedded steel plates 2 embedded in the concrete inside the two tower legs respectively; the load-bearing plates 3 are horizontally set above the decorative panel 1, with the lower ends of both sides of the decorative panel 1 welded to the lower ends of the embedded steel plates 2 on the two towers respectively, and the two ends of the load-bearing plates 3 welded to the upper ends of the two embedded steel plates 2 respectively; multiple vertical support plates 4 are welded between the bottom surface of the load-bearing plates 3 and the decorative panel 1, and multiple horizontal stiffening plates 5 are welded between the decorative panel 1 and the embedded steel plates on both sides respectively.

[0012] In a specific implementation of this utility model, in order to ensure that the decorative panel is subjected to uniform force, multiple vertical support plates 4 are symmetrically arranged on both sides of the arch of the decorative panel.

[0013] In a specific implementation of this utility model, several shear nails 6 can be provided on the inner wall of each pre-embedded steel plate 2. The shear nails are poured into the cable tower concrete, thereby ensuring that the pre-embedded steel plate can be firmly bonded to the cable tower concrete.

[0014] In a specific implementation of this utility model, several shear studs 6 can be provided on the top surface of the load-bearing plate 3. The load-bearing plate serves as the bottom formwork for the construction of the upper crossbeam of the cable tower intersection section. After the upper crossbeam is poured, the load-bearing plate is not removed and serves as a permanent structure of the upper crossbeam. The shear studs ensure that the load-bearing plate and the concrete of the upper crossbeam are firmly bonded together.

[0015] The construction method for the cable tower decorative panel structure that also serves as a load-bearing support is as follows:

[0016] (1) As Figure 3 As shown, during the construction of the two tower legs 100, the embedded steel plate 2 is poured into the tower body concrete according to the preset height of the decorative panel, and the surface of the embedded steel plate is flush with the surface of the tower body concrete.

[0017] (2) Process the decorative panel on the ground; the decorative panel can be processed into a whole. In order to reduce the weight of the hanging, the decorative panel can also be processed into two parts symmetrically from the arch, and the vertical support plate and the horizontal stiffening plate are pre-welded to the outer wall of the decorative panel.

[0018] (3) Figure 4 As shown, before the construction of the crossbeam on the intersection of the cable tower, the decorative panel 1 is lifted to the installation position, the horizontal stiffening plate 5 and the lower end of the decorative panel 1 are welded to the pre-embedded steel plate 2 on the cable tower, and the two parts of the decorative panel are welded together.

[0019] (4) Figure 5 As shown, the load-bearing plate 3 is lifted above the decorative panel 1, the bottom surface of the load-bearing plate 3 is welded to the upper end of the vertical support plate 4, and both ends of the load-bearing plate 3 are welded to the upper ends of the embedded steel plates 2 on both sides. In actual construction, in order to reduce the load of the load-bearing plate, the load-bearing plate can be divided into 4 rectangular plates of equal size, with a 2cm gap between every two load-bearing plates to adjust the spacing between the plates.

[0020] (5) Figure 2 As shown, after the load-bearing plate is installed, load-bearing plate 3 is used as the bottom formwork for the crossbeam of the tower junction section, and the crossbeam 101 of the tower junction section is poured. Since multiple vertical support plates are set between the load-bearing plate and the decorative panel, the construction load borne by the load-bearing plate is transferred to the decorative panel through the vertical support plates; the decorative panel is arched, which not only has strong load-bearing capacity itself, but also can transfer the load borne to the tower body, providing stable and reliable support for the construction of the crossbeam.

[0021] After the crossbeam of the intersecting tower is poured, the load-bearing plate will not be removed, but will remain as a permanent structure of the crossbeam.
