Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to the technical field of a tower top construction platform. Background Art

[0002] During the construction of the cable-stayed bridge, the traditional operation method is to use a lifting device such as a tower crane to lift the cable rod and shuttle the cable.

[0003] However, the use of tower cranes for construction has its limitations. For example, the length of its lifting arm is limited, and its position needs to be adjusted multiple times in actual working conditions. In addition, due to the limited space inside the tower crane, the lifting and transportation of anchors, hydraulic jacks and other related materials during the installation of the inclined cables need to be transported multiple times, which will result in a large consumption of manpower and material resources and high costs.

[0004] At the same time, when working at high altitudes, the stability of tower cranes is relatively poor and will be affected by external factors such as wind, which poses a certain degree of safety hazard to construction safety. Summary of the Invention

[0005] In summary, the present invention addresses the deficiencies of the existing technology and proposes a tower top construction platform, which aims to provide a safer, more efficient and stable working environment to improve construction efficiency and safety while reducing construction costs.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A tower top construction platform, comprising embedded parts arranged at the top of a cable tower and prefabricated supports fixedly connected to the embedded parts, the embedded parts comprising first embedded parts embedded in the top ends of the wing walls on both sides of the concave portion and second embedded parts embedded in the concave portion, the prefabricated supports comprising a base plate fixedly connected to the first embedded parts and the second embedded parts, columns and inclined rods respectively provided on both sides of the base plate in the direction of the back cable surface, and the second embedded parts serving as support legs;

[0008] It also includes lifting door frames arranged on both sides of the cable-facing surface of the base plate.

[0009] Compared to existing technologies, this design incorporates embedded components at the top and inside of the concave portion of the tower's back cable face. Through the fixed connection of these embedded components to the base plate and the installation of columns and diagonal rods, a stable working platform is formed. Furthermore, hoisting gantries are installed on both sides of the cable face, allowing the installation of the stay cables to be completed from a tower-top construction platform without the need for a tower crane.

[0010] In some embodiments, the embedded parts include two groups of first embedded parts and four groups of second embedded parts on both sides of the back cable surface.

[0011] In a preferred embodiment, among the four groups of second embedded parts, at least one group of second embedded parts is attached to the inner wall of the tower wing wall.

[0012] In a preferred embodiment, the embedded parts and the base plate are connected by welding.

[0013] In some embodiments, the base plate is provided with an index hoisting area, and the hoisting gantry is arranged in the index hoisting area.

[0014] In some embodiments, the base plate is provided with a hoist arrangement area inside the index lifting area.

[0015] In some embodiments, the bottom plate is provided with a shuttle arrangement area on the side of the winch arrangement area.

[0016] In some embodiments, a guardrail is further included around the periphery of the bottom plate.

[0017] In some embodiments, it also includes a support frame arranged on the flanges on both sides of the cable facing surface and abutting against the prefabricated support. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0027] A cable tower construction platform in this case is set on the top of the cable tower. Please refer to Figure 7 and Figure 8 ,in Figure 8 It is the cable-facing surface of tower 1, that is, the direction in which tower 1 faces the insertion of the inclined cable. Figure 7 It is the back-cable surface, that is, the non-cable surface. In this case, it is described as the back-cable surface and the cable surface.

[0028] Please refer to Figures 1 to 3 In this case, a tower top construction platform includes embedded components installed at the top of the tower cable 1. The embedded components are installed in a concave structure, at least on the back cable surface of the tower top 1. The embedded components include a first embedded component 110 installed at the top of the wing walls 11 on both sides of the concave structure, and a second embedded component 120 installed within the concave structure. To ensure that the first embedded component 110 and the second embedded component 120 are in the same plane, the second embedded component 120 is a support leg structure.

[0029] Specifically, please refer to Figure 3 The embedded parts include two sets of first embedded parts 110 and four sets of second embedded parts 120 on either side of the cable face. Preferably, one set is provided on each side, but additional embedded parts can be added as needed. Preferably, at least one set of second embedded parts 120 is attached to the inner wall of the wing wall 11 to enhance stability.

[0030] After the embedded components are set, the prefabricated support 200 is fixedly connected to the embedded components. Specifically, the prefabricated support 200 includes a base plate 210 fixedly connected to the prefabricated components. Vertical columns 220 and diagonal bars 230 are located on either side of the base plate 210, facing the cable-back surface, forming a stable work platform. These columns are located on either side of the cable-back surface. Specifically, the base plate 210 and embedded components can be connected by welding, and a protective guardrail 240 can be installed around the base plate 210.

[0031] Please refer to Figure 1 and Figure 4 With a stable working platform, hoisting gantries 300 can be set on both sides of the cable-facing surface of the base plate 210, so that the installation of the inclined cable can be completed using the tower top construction platform without the need for a tower crane.

[0032] As a working platform, the layout of the bottom plate 210 is as follows: Figure 5 The bottom plate is provided with index hoisting areas A and B, and the hoisting gantry 300 is arranged in the index hoisting areas A and B. At this time, the hoisting machine arrangement areas E and F are arranged inside the index hoisting areas A and B. Please refer to the working status at this time. Figure 6 In the figure, the hoist 20 works in conjunction with the hoisting gantry 300. Furthermore, the rope threading machine arrangement areas C and D are provided on the sides of the hoist arrangement area.

[0033] Please refer to Figure 8 In some embodiments, partial flanges 12, i.e., relatively recessed portions, may be provided on both sides of the cable face. Support frames 400 are provided on these flanges 12 to abut against the prefabricated supports 200. The work platform can be further expanded. In this case, the two sides of the cable face are the left and right sides as shown in the figure, where left and right represent the directions shown in the figure.

[0034] As mentioned above, this case protects a tower top construction platform, and all technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
