Description

Technical Field

[0001] The utility model relates to the technical field of operating platforms, in particular to a steel wire rope flexible operating platform for high-altitude operations in hollow areas of buildings. Background Art

[0002] In the design of public buildings, there are usually hollow areas above halls or large light wells, and high-altitude construction such as steel structure hoisting or glass dome is usually required above this area, which is difficult to construct. Usually, this area needs to be equipped with ground-based or cantilevered full-hall operating scaffolding to assist in high-altitude construction. However, if this method is used for construction, on the one hand, the construction period of full-hall scaffolding is long, which is not conducive to the control of construction period; on the other hand, if the scaffolding is set up too high, the danger will be greatly increased, and the amount of materials input will increase, resulting in an increase in unnecessary construction costs.

[0003] In the existing flexible operating platform, for example, the Chinese utility model patent with patent number CN201120079160.1 discloses a cable suspension flexible construction platform, which includes transverse cables and longitudinal cables arranged parallel to the horizontal plane, the transverse cables and longitudinal cables are arranged vertically and crosswise to form a mesh structure, the two ends of the transverse cables and longitudinal cables are fixed to the crossbeam by anchor bolts, and the working surface is laid on the mesh structure. The front ends of the transverse cables and longitudinal cables are heart-shaped ring structures, and the heart-shaped rings are connected to the anchor bolts by a basket bolt. The patent also has the following problems:

[0004] 1. The transverse cables and longitudinal cables of the patent are fixed on the crossbeam, but the height of the crossbeam and the design spacing of the top steel structure or glass dome in the hollow area are not fixed. The height of the crossbeam may not be suitable for the height of the operating platform. If the crossbeam is too low or too high, it will be difficult for the operators to construct the top steel structure or glass dome after the construction platform of the patent is erected.

[0005] 2. The spacing between the transverse cables and the longitudinal cables does not exceed 1m, while both ends of the transverse cables and the longitudinal cables of this patent are anchored to the beams by chemical anchors. It is necessary to drill a row of anchor holes with a spacing of less than 1m on the beams in advance. The large number of holes is very destructive to the beam structure and may seriously affect the safety of the main structure of the building.

[0006] 3. After laying, the dense mesh and nylon net need to be fixed on the transverse and longitudinal cables. The patent does not disclose the structural features of fixing the dense mesh and nylon net. The traditional method is to fix them by tying them with ropes, but the high-altitude tying and fixing method is more troublesome and inefficient, which affects the construction progress.
