[0017] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0018] The first embodiment of the present application is as follows:

[0019] Please refer to Figures 1-3 , Figure 1 It is a schematic diagram of the overall structure of a spiral staircase of a cable - steel structure according to the first embodiment of the present utility model, Figure 2It is a schematic structural diagram of the cable device according to the first embodiment of the present utility model. Figure 3 It is a schematic connection diagram of the connecting support and the fixed support according to the first embodiment of the present utility model.

[0020] The present utility model provides a spiral staircase with a cable steel structure, which includes a staircase body 101, a fixed rod 102, and a first handrail 103. It further includes a cable device, and the cable device includes a steel cable 104, a connecting column 105, a connecting support 106, and a connecting component. The connecting component includes a fixed block 107 and a fixed support 108. The staircase body 101 further includes an inner guard plate 109, and the staircase body 101 further includes a support steel plate 110. By the foregoing solution, the problem that the conventional spiral staircase usually spirally distributes around the middle column is solved. However, for this kind of middle-column spiral staircase, when pedestrians walk on the outer side of the staircase, the staircase will shake, thus bringing potential safety hazards. It can be understood that this solution can also be used to solve the problem that children are prone to potential safety hazards when walking.

[0021] In this embodiment, through the mutual cooperation of the steel cable 104, the connecting column 105, the connecting support 106, and the connecting component, the staircase body 101 can be firmly fixed on the building body, avoiding the staircase body 101 from shaking during use, thereby enhancing the safety of the staircase body 101.

[0022] Among them, the connecting support 106 is installed on the staircase body 101 through the connecting component. The connecting column 105 is fixedly installed on the connecting support 106. The steel cable 104 is fixedly installed on the connecting column 105 and is located at one end of the connecting column 105 away from the connecting support 106. The number of the staircase bodies 101 is multiple groups and is spirally distributed. Each group of the staircase bodies 101 is provided with a group of the fixed rods 102. The first handrail 103 is spirally distributed at the upper ends of multiple groups of the fixed rods 102. The number of the cable devices is two groups and is symmetrically distributed along the axis of the staircase body 101 on the upper and lower sides of the staircase body 101. The connecting support 106 has a U-shaped structure. The steel cable 104, the connecting column 105, and the connecting support 106 are all made of steel materials. Through the mutual cooperation of the steel cable 104, the connecting column 105, the connecting support 106, and the connecting component, the staircase body 101 can be firmly fixed on the building body, avoiding the staircase body 101 from shaking during use, thereby enhancing the safety of the staircase body 101.

[0023] Secondly, the fixing block 107 is mounted on the staircase body 101; the fixed support 108 is fixedly installed on the fixing block 107 and is rotatably connected to the connecting support 106. The fixing block 107 is fixed to the staircase body 101 by screws. The fixed support 108 is triangular in shape as a whole, and its upper end is an arc structure. The fixed support 108 and the connecting support 106 are rotatably matched through a pin shaft. Through the cooperation of the fixing block 107 and the fixed support 108, the connection effect between the connecting support 106 and the staircase body 101 can be achieved.

[0024] Thirdly, the inner guard plate 109 is fixedly installed on the staircase body 101 and is located on the side of the staircase body 101 away from the fixed rod 102. The inner guard plate 109 is a plate-like structure and is located inside the building body. The number of the inner guard plates 109 is multiple groups, and one group of the inner guard plates 109 is provided on one side of each staircase body 101. The multiple groups of inner guard plates 109 form a spiral shape. Through the arrangement of the inner guard plates 109, pedestrians can walk more safely.

[0025] Finally, the support steel plate 110 is fixedly installed on the staircase body 101. The support steel plate 110 is a fan-shaped structure. The support steel plate 110 is located at the middle position of the staircase body 101. By fixing the support steel plate 110 on the floor, the stability of the staircase body 101 can be strengthened.

[0026] In this embodiment, during installation, the end of the steel rope 104 far from the connecting column 105 is fixed to the building body. Since the connecting support 106 and the fixed support 108 are rotatably matched, the steel rope 104 can be adjusted during installation. At the same time, the support steel plate 110 is fixed to the floor, and then the installation is completed. During use, pedestrians can go up and down by holding the handrail. At the same time, the fixed rods 102 and the inner guard plates 109 on both sides can protect pedestrians. Thus, through the mutual cooperation of the steel rope 104, the connecting column 105, the connecting support 106 and the connecting components, the staircase body 101 can be firmly fixed to the building body, preventing the staircase body 101 from shaking during use, thereby enhancing the safety of the staircase body 101.

[0027] The second embodiment of the present application is as follows:

[0028] Please refer to Figure 4 , in which Figure 4 is the overall structural schematic diagram of a cable-stayed steel structure rotating staircase according to the second embodiment of the present invention. On the basis of the first embodiment, the cable-stayed steel structure rotating staircase of this embodiment further includes a second handrail 201.

[0029] In this embodiment, the provision of the second handrail 201 enhances the safety of children when walking.

[0030] Among them, the second handrail 201 is fixedly installed on the staircase body 101 and is located on the side of the staircase body 101 close to the first handrail 103. The second handrail 201 has the same structure as the first handrail 103, both being spiral tubular structures. The height of the second handrail 201 is lower than that of the first handrail. Through the provision of the second handrail 201, it is convenient for children to hold when walking and assist in walking, thereby enhancing the safety of children when walking.

[0031] In this embodiment, through the provision of the second handrail 201, it is convenient for children to hold when walking and assist in walking, thereby enhancing the safety of children when walking.
