A method for rapid installation and demolition of an aerial steel cable platform

Abstract

The present invention relates to a method for the rapid installation and demolition of an aerial cable platform, including S1: installation of the cable platform and S2: demolition of the cable platform. In the present invention, a cable platform is erected between two buildings on both sides as an operating platform, which is erected quickly and conveniently, and can greatly save human and material resources. Since the overall weight of the cable platform is too heavy, the cable platform is divided into several cable platform blocks. During demolition, two electric hoists are installed on the buildings on both sides, and the cable platform blocks can be smoothly lowered by removing the anchoring points. The demolition work is very fast, which is beneficial to the construction period control. The demolition is not restricted by the operating space, and there is no need for personnel to work at height, which can reduce potential safety hazards.

Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and particularly relates to a method for quickly installing and demolishing an aerial steel cable platform. Background Art

[0002] In recent years, with the rapid urban development, connected high-rise building groups have emerged. That is, multi-story aerial steel structure corridors are used to connect two or more high-rise single buildings into a whole, enriching the use functions of high-rise buildings and the utilization rate of the aerial space. Most of the main structural frameworks of the steel structure corridors are fixed after being integrally lifted, and for some overweight main structural frameworks of steel structure corridors, large-tonnage cranes and tower cranes are required for piecemeal assembly and fixation. After the main structural framework of the steel structure corridor is fixed, external decoration construction still needs to be carried out on it.

[0003] Whether it is piecemeal assembly or external decoration construction, an operating platform needs to be erected below the main structural framework of the steel structure corridor for construction. The operating platform has a high aerial height and a large span. If the traditional full hall scaffold support scheme is adopted, the scaffold erection density is large, the height is high, the construction difficulty is great, the erection and demolition cycle of the operating platform is long, which is not conducive to the construction period control, and high-altitude operation is required during demolition, posing a safety hazard. Therefore, it is necessary to develop a method for quickly installing and demolishing an aerial steel cable platform to solve the above problems. Summary of the Invention

[0004] The main purpose of the present invention is to propose a method for quickly installing and demolishing an aerial steel cable platform, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0006] A method for quickly installing and demolishing an aerial steel cable platform includes the following steps:

[0007] S1: Installation of the steel cable platform, which includes the following steps:

[0008] S1.1: According to the plane layout, the steel cable platform is evenly divided into several steel cable platform blocks;

[0014] S2: Demolish the cable platform, including the following steps:

[0015] S2.1: Install demolition anchor points at the four corners of the cable platform block to be demolished. Each demolition anchor point is fixedly connected to the outermost main cable of the cable platform block by a first steel wire rope, and then the tails of the two first steel wire ropes are braided and fixed into a loop.

[0016] S2.2: Install a disassembly operation frame on each of the two side buildings, and install an electric hoist on the disassembly operation frame.

[0017] S2.3: Fix the tails of the two first steel wire ropes on the same side to the first hook of a turnbuckle, fix a second steel wire rope to the second hook of the turnbuckle, and finally fix the tail of the second steel wire rope to the hook of the electric hoist.

[0018] S2.4: Tighten the two first steel wire ropes through the turnbuckle, and then cut off all the cut-off points of the main cables within the cable platform block, so that the cable platform block is suspended on the electric hoists on both sides.

[0019] S2.5: Lower the hooks of the electric hoists on both sides simultaneously, so that the cable platform block drops to a position where the operator can reach without the need for tools.

[0020] S2.6: Demolish all cable platform blocks in sequence, and the demolition of the cable platform is completed.

[0021] Preferably, in step S1.1, the spacing between cable platform blocks is 6 m.

[0022] Preferably, in step S1.2, the buckle is a U-shaped wire clip, and the adjacent buckles face different directions and are arranged in a "V" shape.

[0023] Preferably, in step S1.4, the anchoring method of the main cable is that the main cable passes through the building and is fixed by steel plates and anchors.

[0024] Preferably, in step S1.4, when the steel wire rope is tensioned, it is strictly implemented in accordance with the tensioning procedure and its tensioning value is checked.

[0025] Preferably, in step S2.1, the first steel wire rope is fixedly connected to the main cable through three U-shaped wire clips, and the tail of the first steel wire rope is braided into a loop and fixedly connected through three U-shaped wire clips.
