2, Suspended platform wide application on high rise window cleaning (facade cleaning)

With more and more high rise buildings appearing all over the world, high rise building cleaning has become more and more important. The article mainly introduces the suspended platform (swing stage) application on the high rise building facades cleaning, and its advantages than BMU and Bosun’s chair.

Exterior works of high rise building include high rise window cleaning, exterior wall cleaning, curtain wall clean, high-rise exterior wall paint, concrete repairs, sealing and aerial advertising installation etc. This article mainly introduces the application of suspended work platform in high rise external wall cleaning.

According to the characteristics of high-rise building, the main equipments that are used in exterior wall cleaning include three kinds as below:
1)    Building Maintenance Unit, also is called BMU
2)    Temporary Suspended Platform or Swing stage
3)    Bosun’s chair

The BMU is a special equipment for exterior wall cleaning of high-rise building. Its main usage is cleaning exterior wall of modern high-rise building, which change the traditional suspended work operation into automatic, efficient, high quality mechanical operation. It is the latest generation of powerful exterior wall cleaning robot, and fills up the blank from domestic to overseas in high-rise building exterior wall maintenance. In China, some of senior high-grade constructions, which were built in 80-1990s, were designed by foreign architects and they had considered the installation of BMU since then and adopted abroad BMU to maintenance building. These efforts have laid a good foundation for building cleaning. But since 1990s, there are many buildings had not considered the application of BMU when they were designed and some of them can not be installed BMU, at the same time, BMU does not belong to standard products and also often bring higher cost, all of those lead to BMU has not been widely used nowadays.

Because of Bosun’s Chair’s flexibility, it has been widely adopted in the world. However, as its risk in operation and often brings accidents, the Bosun’s Chair has been more and more replaced by suspended work platform. We believe this is a tendency of development. Now, in China, many cities have already stipulated that in aerial work cleaning, workers must use suspended work platform and forbid to use Bosun’s Chair , to avoid more accidents happening.

The suspended work platform is a new type of aloft working machinery. Because of it’s operate smoothly, comfort, safety, energy saving etc, it has been widely used in domestic decoration and cleaning industry.

The main materials of exterior wall include glass curtain wall, Aluminum composite plate, marble, granite, mosaic, ceramics, drying sticky stone, granitic plaster stone and so on. Due to the dust, grease and erosion caused by acid rain (fog), the new buildings become smudgy easily in short time, especially in some serious air pollution cities.

According to the weight-bearing ability, the suspended work platform can be divided into 1000kgs, 800kgs, 600kgs, 500kgs and 250kgs etc. According to the length of platform, it contains 10m, 7.5m, 6m, 4m, 2m and so on. The length of platform can be assembled to suit for different requests. Now the main types that are usually used in cleaning industry include ZLP630 and ZLP250 and the length ranged from 6 to 10 meters is more popular.

7)    To check if the fixed position where the safety rope joined on the top of building is firmly.
8)    To check if the staff dresses meet the following requirements: wearing a helmet and wearing long-sleeved work jacket and long pants. In corrosive environment, let workers wear corrosion-resistant clothes and shoes with soft bottom, which also features of corrosion-resistant.
9)    To check if the junction between safety rope and building parapet has the liners. If found no, we shall be stop working immediately.
10)    The employee’s self-lock device installed on insurance belt should be knotted on safety rope, not buckle in suspended platform.
11)    Please set up the fence in operation area and arrange one ground security officer to preventing pedestrians. If no security officer or protecting fence, we should stop the work. 12. Check the attitude of workers who operate in top of buildings, if have some problems, stop working.

Operation process
1)    Use water gun to wash corners and remove dust.
2)    Dip spreader into barrels and after it fully absorb sanitizer, we smear evenly on the surface of glass. Later use wiper scrape glass up and down including window frame and corners. Ensure to pull crossly and no miss some small place and then use towel dry it.
3)    After finishing one position, let the platform move to the below site and when end the cleaning from top to bottom, we turn left or right to adjacent position and continue to work from top to bottom again.
4)    After finishing total work, sorting machines and tools and remove fences and billboard and clean the water on ground.
5)    Cleaning and maintenance equipment and after removing dust and dirt we pack the device in warehouse.

3, Difference between the scaffold and suspended scaffolding

1)    What is scaffold
The scaffold refers to various brackets which are laid to solve vertical and horizontal transportation for the workers in the construction site. Scaffold is the universal term in the architectural field and is used in the places where outer wall and inner wall are decorated or the building in high floor can’t be directly constructed. Scaffold is mainly used for construction, periphery safety grid maintenance and overhead installation, etc., that is lay the scaffold Universally, the scaffold is made of bamboo, timber, steel tube, composite material, etc. Some projects uses the scaffold as a template; moreover, it is widely used in advertising industry, municipal facility, traffic road and bridge, mine and other departments

2). What’s suspended platform
The suspended scaffolding is high-efficiency modern overhead operation equipment capable of replacing a traditional scaffold and being reused. Generally, the suspended scaffolding can be divided into two kinds: manual and electric. It is widely applied to the outer wall construction, curtain wall installation and outer wall cleaning and maintenance in high rise; and it can be also applied to large tanks, bridges, dams and other engineering operations.

The suspended scaffolding is manufactured by the manufacturer with the building mechanical production license ; its product quality must meet the stipulation of industrial standards “Safety Inspection Standard of Building Construction” and “Safety Rule of Suspended Platform for Overhead Operation”; moreover, the construction company uses the suspended platform which is recommended by the building safety supervision institution and is identified to be qualified according to “Supervision Management Rule of using Safety Protective Tool and Mechanical Equipment in Construction Site”; No matter which kind of suspended platform or scaffold is used, it must verify the strengthen and rigidity of the working platform and the outrigger structure and the safety coefficient of the steel wire is verified; and all data and reports need to be reviewed and approved by the superior.

Wherein, the member node of the bowl clasp type scaffold is connected by the bowl clasps, which is in stable connection; the combined scaffold has good integration performance; therefore, it has rapid development in application while the gate-type steel tube scaffold can be used as the external scaffold, inner scaffold and full scaffold; it has the features of standardized dimension, reasonable structure, good stress performance, easy detachment and installation in construction, safety, reliability, economy and practicability and thus becomes one of the commonest scaffolds in the world.

If the wheels are installed under the gate frame, it can be used as a mobile worktable for motor installation, painting, equipment maintenance, ads manufacturing; moreover, the external scaffold in the construction has two kinds: single row and double rows; there is only one row of vertical columns in the single row type; the other end of the horizontal pole is born on the wall; the scaffold on the metope needs to be repaired. The external scaffold needs to be bond with the outer wall to increase its stability. One binding piece can be set every three steps and spans; the binding piece can be divided to a rigid type and a soft type. The inner scaffold is installed inside the buildings and used for bricking the wall or decorating the inside. Generally, the inner scaffold is a tool type including a folded type, a support column type, a gate frame type and other structural forms; and it has the features of portability, flexibility, convenience in installation and detachment.

(2)The application scope of the hanging basket is shown in three aspect below:
A. Building decoration, cleaning, and maintenance. As building cleaning and maintenance equipment, the hanging basket is widely adopted in high rise. It can be matched with many device on the roof to complete the cleaning and maintenance, which is simple and reliable in operation and low in maintenance cost.

B. Bridge overhaul, maintenance and construction

C. Application in other industries.
The hanging scaffold is widely applied to vessel decoration in the vessel manufacturing industry, installation and maintenance of large-scale cables, overhaul of large dams and installation of shaft elevator orbit.

4) Compared with the scaffold, which advantages does the suspended platform have?
The scaffold shall be used in the building with stories less than 6 floors. Generally, the height of the scaffold is about 2 meters, which is accumulated and laid one by one; considering its stability, the scaffold is also used in low-story buildings or ad plaque.

The electric hanging basket is special for constructing the outer wall of building; and it is always used in high rise with 30-stories
Moreover, compared with the full steel tube scaffold for outer metope, the suspended platform for constructing the outer wall has the advantages of rapid build-up speed, saving of mass scaffold materials and labor, convenient and flexible operation, good technical and economic benefits. Specifically, it includes:
A. save the rental fee
During the construction of main body, it adopts a subsectional hanging method; after completing the main body, total scaffolds are detached; and the powered suspended platform is used to greatly save the rental fee and shorten the pipeline use time; and it is very rapid, convenient and safe in construction.

B.   save the safety grid, paint, and frame plate; Chengdu Scaffold Rental
It adopts subsectional hanging in the construction site; total scaffolds are detached after it cuts off water for the main body; therefore, the safety grid, the pocket grid and the paint have little amount; and it doesn’t need the fully-laid frames; and it can save the production cost again.

C. save labor fee
During the construction period, it adopts vertical transportation in the construction site; when building up the outer frame, it can greatly alleviate the labor strength of the operator; if the condition allows, it can adopt a single-row protective frame in the individual place or part, thereby reducing the labor cost caused by vertical transportation.

D. save transportation fee, consumption, loading and unloading fee, and joist beam cost
