With more and more tall buildings are everywhere, cleaning of tall buildings has become increasingly important. Building high-rise window cleaning skyscrapers including the external cleaning of external walls, curtain walls clean, high-rise exterior wall paint, concrete repairs, waterproofing and installation of aerial advertising, etc. document presents the main platform suspended (swing stage) application on the facades of high-rise buildings with cleaning, and its benefitsat LSU and president of captain.

Depending on the characteristics of the skyscrapers, the main equipment used for cleaning the exterior walls contain three types:

1. Building maintenance units, also called BMU
2. Temporary suspended platform or stage of rotation
3. The captain of the Presidency

The BMU is a special equipment for cleaning the exterior walls of skyscrapers. Its main use is to clean the outer wall of modern skyscrapers, changing the traditionalsuspended the operation of labor exploitation as an auto mechanic, efficient and high quality. This is the latest generation of powerful cleaning robots outside the home and fills the void outside maintenance at high growth outside of the wall. In China, some of the high-quality buildings that were built 80 years in 1990, were designed by foreign architects, and had considered the installation of CO subsequently adopted abroad and building maintenance UGB. These effortslaid a good foundation for building cleaning. However, since 1990, many buildings had not considered the application of LSU, when designed and some of them can not be installed BMU, but LSU does not belong to the standard products and often provide an increase in costs, to all those who lead to the UGB is not widely used today.

Because of the flexible model President, which has been widely adopted around the world. However, the risk to the operation and often cause accidentsPresident of the model has always been the work of aerial platforms. We believe this is a trend of development. But in China, many cities have already demonstrated that the cleanliness of aerial work, workers must use the platform suspended from work and prohibit the use of model President, to prevent accidents.

The platform has suspended the work of a new type of machines at high altitude. Because of his operation, comfort, safety, energy conservation, etc., which has been widely used indecorating and industrial cleaning.

The main external wall materials include glass curtain walls, aluminum composite marble, granite, tile, ceramic tile, granite, stone and plaster dries sticky so on. Because of dust, grease and erosion caused by acid rain (fog), the new buildings are easily spotted in a short period of time, especially in some cities, air pollution seriously.

According to the load capacity, work platforms can be divided into 1000kgs, 800kgs,Etc 600kgs, 500kgs and 250kgs depending on the length of the platform, which contains 10 m, 7.5 m, 6 m, 4 m, 2m, and so on. The length of the platform can be assembled to meet different needs. Now, the major types that are commonly used in the cleaning industry and includes swing ZLP630 ZLP250 and duration varies from 6 to 10 meters is more popular.

The preparatory work before the work

1. Visit and work to ensure the plan. Check and make sure that the roof can be installedplatform suspended from his job and that the movement is not opposed to the neon lights and posters. The design plan of the construction engineers.

2. To ensure the environment of the building, no wind, snow and high temperatures, the phenomenon of low temperature. The wind at the site should be 6 levels.

3. Prepare the cleaning tools such as buckets, spray, towels, and the miller

4. Two workers carry cleaning tools, the holder of the platform and tighten the belt.

No security check beforeoperation.

1. To check all the rooms of the working platform suspended (swing phase) for consideration, if the fasteners, accessories, lifting equipment, and security guards in good condition and check that there is hidden danger before work.

2. To test whether the suspension mechanism installed on the latch of the roof, drawing the chains are still hidden problem and confirm each transaction.

3. To control the length of the cord and see if there is damage or break in the action.

4. Correction lifelineand confirm the length is greater than the height of the building.

5. To check belt that employees use without damage.

6. To check the safety lock flexible and reliable.

7. To check whether the fixed position on the rope together at the top of the building is tight.

8. To check whether the clothes of the officials meet the following requirements: a helmet and a jacket with long sleeves and long pants. In a corrosive environment, enabling workers to wear and corrosion resistantShoes with soft soles, which also resists corrosion.

9. To check if the connection between the lifeline and the parapet of the building. If not found, we stop work immediately.

10. Auto-lock device installed in the seatbelt of employees must be connected to the lifeline, not buckle hanging platform.

11. Please set the fence in the area of ​​operations and organization of a security guard to the ground to avoid pedestrians. If no security guard orprotect the fence, you should stop working. 12. Check the attitude of workers who operate at the top of the buildings, has some problems, stop working.

Operation of the process

1. Water pistol used to wash the corners and remove the dust.

2. Immerse retractor in the barrel and completely absorbed after disinfectant, that the stains on the glass surface uniformly. The next time you use the scratch windshield up and down, including window frames and corners. Be sure to take humor and without losing a small area and then use a dry cloththat.

3. After finishing position, the platform will allow the passage beneath the site and reach the final cleaning from top to bottom, left or right turn and continue working up and down again.

4. After completion of total work, machines and tools for sorting and removal of fences and billboards, and clean water in the soil.

5. Equipment for cleaning and maintenance, and after removing the package device dust and dirt in the store.

Cover Meter ConcreteRestoration of the bridge deck cleaning

Any piece of wood is not protected in nature shows signs of deterioration in a year or two. E 'in the nature of nature to affect the materials that are now dead – including pieces of wood that make up the deck or fence. In this case, sunlight and rain are the main instruments. Wood exposed to the outside sunlight is weak and gray as the sun breaks up its internal fibers. A similar pattern occurs when rainwater penetrates into the wood and makesswell. The result is a fluffy. Morning dew and afternoon sun and then set the forest every day to reduce the swelling cycle, accelerating the process of deterioration. gray surface, deformation, division, and the nails are loose indications of the difficulty of the wooden elements that are responsible.

The need to treat wood

Wood, even if it was pressure treated, must still be cleaned and sealed to prolong its life. Decks and fences of pressure-treated wood still require regular cleaningand sealed to ensure they remain in good condition. While the pressure of the tires and wood fences cedar, cypress and other exotic woods are protected from insects, but are not impervious to the corrosive effects of time. bare wood can be a danger in just seven years.

When you are ready to seal the wood?

When it came time to seal the wood? Some say that wood should be sealed after one year so that the wood is completely dry. However, ayears is too long to wait to seal the wood. Meanwhile, the wood would take too much damage, most of which can not be reversed. The wood can be completely dry and ready to seal in two or three months. It was found that the timber was sealed within three months is much better than trying to dirable wood was closed after one year. You can tell if the wood is ready for sealing. Professionals use an electric moisture meter to determine if the wood can besealed. However, a simpler method is to spray water droplets on the surface of the wood. If the water is absorbed rapidly, which means the wood is dry enough that it is ready for sealing.

Prepare the wood for sealing

The closing process begins with the preparation of wood for cleaning. The most important step to take care of bridges and fences should produce the following results: a) the removal of dirt, mold and algae, b) opening the pores of the wood, and c)the pH balance to allow the sealant to bond with each fiber. Pressure washing is the most common way to achieve this goal.

Choosing the right cleaning product

The next step is to choose the right cleaning product that may not be as simple as that. You may have to deal first with the complexity of the fact that the cover and clean the compound around pH must be acidic, neutral or alkaline. The market for selling "do it yourself at neutral pH and reasonably safe to use a cleaning powder. MostDIY instead recommend acid-based compounds as they are safer alkaline, homeowners on average to administer. They are also much less effective. Favorably in the alkaline-based cleaners for the consumer on the other hand, are much more effective. experienced entrepreneurs, of course, know better. The most successful of them use a two-step process. Is cleaned with an alkaline base, and then neutralize the acid with a Polish. This procedureallows the natural colors "spring" of the wood, making the bridge look great, even before it is closed. Professional cleaning products obtained from industrial suppliers of prime contractor. The products offered by dealers and hardware stores are not clean in terms of performance.

Dry Wood

A choice of cleaning the wooden bridge jet Atlanta with high pressure water, with or without cleaning products mixed in the pressure washing removesgray wood, but can also damage the surface with ease. Much water is needed for this technique, and it is important to apply the right amount of pressure and have the right kind of cleaning solution. DIY should be protected by applying too much pressure. pressure washing equipment leased to owners are typically designed to spit water at 1750-3500 pounds per square inch (psi), which is good for cleaning concrete and remove the old paint. However, thesePressure washers are too powerful for wood. The ideal amount of pressure is between 500 and 800 psi. At this level of pressure contractors with experience of working in wood using chopsticks specially adapted for pressure washers. See pressure washing Atlanta for more information. Another warning: Do not use hot water pressure washer on wood, because wood from damage to a sharp increase in its grain.

Select type of sealant

His platform is designed for all the losses -bright and clean as a whistle. It 's time to choose a sealant and decide how much you're willing to spend on one. There are three types of insulation to choose from, each with distinctive characteristics: a base oil, wax and resin. Recently, the hunters to latex have entered the market. The prices are extremely uneven across these product categories, and we recommend that you use the value "for money, as a guide most of your buying decision. Wait disappointed by the results, ifchoose a product cheaply.

Wax

These hunters are usually found in stores "do it yourself, and are the most heavily advertised on TV. The producers can afford to spend a fortune on advertising for these products because they are cheaper to produce. Sold as little as $ 12 to $ 15 per gallon. Its effects are relatively temporary closure, "" six to eight months, when they expire, the bridges are used to turn black. Sealers cleaned with soap and waxwater. They are identifiable by the "accounts" of water on surfaces where applied. In general, it can hardly be taken as the value of your time and money.

oil-based sealant

Like their counterparts on the basis of wax, oil-based hunters, clean with soap and water. There are two ways – one of the vegetable oils (such as linseed oil or tung) and other crude oil. That penetrate the wood better, giving a soft and natural. L 'plant varieties, however, give a glow to the wood surface and uniform layer with a varnish. However, they contain natural sugars and starches that can promote the growth of mold and fungi. They are also very difficult to remove, and require removal before the wood can be sealed. This is particularly true for the type of covering clothing. An important advantage of GDP is not normally must be removed before closing. When the time comesreconstructing the fence or a terrace, a new coating can be applied directly to the old plaster. However, you can easily remove the hunters gross and cheap if you wish. You can consider this an added benefit: the lower the initial investment, you get to keep the forest in search of natural beauty. oil-based sealants can be bought in shops "do it yourself" is often mixed with vegetable oils, which last between 12 and 18 months before it becomes a new closurenecessary, the shorter the life of 24 months you can expect quality commercial rates. oil-based sealants vary widely in quality and are priced between $ 15 and $ 30 a gallon.
