home escalator suppliers

The fire resistance of cast-in-situ reinforced concrete structures is generally above 3 hours.5 hours to 3 hours.In order to ensure that the fire elevator can continue to work under any fire conditions, the shaft wall of the elevator shaft must have sufficient fire resistance, and its fire resistance level should generally not be home escalator suppliers lower than 2.

This floor is quiet, not affected by car exhaust and so on, and it does not cause people to reach a height of fear. For the upper room, the process is reversed, which causes the air in the upper room to actually flow from the dirty air in the lower room. . The 'back of the head' of the building, 'enjoying' the various types of photoelectric pollution in the city, can it be said that the scenery is good? In fact, many of the high-rise residents who want to view the scenery have become 'landscapes'. Ordinary multi-storey houses are generally brick-concrete structures, and high-rise houses are reinforced with cast-in-situ concrete, with deep and strong foundations, thick walls, impervious to water, and better seismic performance than multi-storey buildings.

The most ideal residence for people should be close to the ground and close to nature. Hitachi's rocket elevator will be installed in the Guangzhou CTF Finance Center, with a total of 111 floors, and is expected to be completed in 2016. However, the low floor is relatively reduced in noise due to the obstruction and absorption of surrounding low buildings and trees. However, life close to the ground is also inadequate: the first to third floors are very close to the ground.

As shown below: Unfortunately, this situation is almost impossible in general buildings. At the moment, there is a 'high-density area of ​​pollutants' in the middle of high-rise housing in many densely populated areas. It turns out that sometimes the sound will go freely up to the windows of the high-rise. Disadvantages: If there are waste discharge pipes above and below these layers, then these layers will be affected the most. That is between 8-11 layers. Few people are willing to go upstairs and spend ten or twenty minutes in the elevator. In China, higher floors tend to sell more expensive. Generally, no party A has an elevator as a selling point. Disadvantages:

Elevator Handrail Suppliers

But in addition, the elevator production Elevator Handrail Suppliers: special equipment manufacturing license (issued by the State Bureau of Quality Supervision), divided into three levels of ABC, the detailed table attached to the certificate will be listed in detail, which enterprise is permitted to produce What is the maximum speed of this type of elevator. In short, please consider the details and let the manufacturer report a closed cost.

The sprayed steel plate is the cheapest and has a variety of colors and patterns to choose from.), installation, inspection, trial operation, maintenance of experimental equipment and special tools , Hoisting scaffolding and dismantling costs, cork leg or steel beam production and installation costs (these two are often forgotten, and later disputes occur), etc. So if you are involved from the beginning of the project, you must pay attention to the size of the foundation pit and the shaft. The hairline steel plate looks a bit high-grade, but it is very durable. Save a considerable part of operating costs.7 Fireman operation function At least one elevator in a high-rise building shall be a fire elevator.75 m / s (1.

Here are some functions that I think should have. The most important thing to note in the procurement process is whether to choose a light curtain or a touch panel. After a long time of use, the surface will have a lot of scratches and need to be replaced, which increases the future operating costs. If the scale is large or the project has a large impact, you can directly invite the manufacturer (you will definitely not come if you buy one or two), and there is also an agent that represents several brands at the same time, so it is easy to choose.

Domestic large elevator brands will emphasize that they use the advanced technology of a high-end brand.2 Reverse internal command automatic elimination function, misoperation cancellation 10. High-level or super-high-level, can be divided into high and low area group control.5 m / s (1. 10. In the bidding process, the construction interface should be specified, where the elevator manufacturer is responsible, and where the low-voltage construction unit is responsible to avoid contract disputes.. 10.

Think about it. With the elevator, the stairs seem to be furnishings. There is a warm reminder that “climbing stairs is good for health” at the entrance of the elevator, but who would give up the elevator and take the stairs? Just like we are accustomed to the feast of life, knowing that crude tea and light rice can keep us away from disease, or we can't control our desire, go to delicious invitations again and again. On the stairs, why wasn't the coarse tea and rice we went away?

From the first floor to the eighth floor, I didn't meet anyone. It turned out that the office building was a multi-story building at the old site of the unit. Every day, people had to take the stairs when they went in and out. Colleagues came and went, and they often met on the stairs. Now, I always turn around the stairs, I don't feel the waiting stairs, like an ordinary old friend, watching and looking forward in the corner deeply. The elevator is an opaque road that never meets. When the elevator allowed us to arrive quickly, we were hidden in our workshop like a bee, and that door was mostly closed or hidden. Silently, we were busy with our own busyness, and gradually separated in the years.

The stairs, in my sense, actually gave birth to greenery, like the winding vines on the big tree in the building. With a kind of static, upward and winding beauty, it cherishes its own space. As long as we are willing, it will give our footsteps a solid support in a green way, and it can reach the height we want.

Only when the footsteps sounded, the vine of the stairs has life and vitality. Like water drops, we slowly rise, or lean down on the vine, flowing between the green veins of the building.

If the elevator is a straight line between the starting point and the destination, then the stairs is the curve between the two points. Since when have we become accustomed to walking straight without giving up every curve without hesitation? Speed ​​is especially important in fast-paced modern life. Faced with the choice of straight lines and curves, we will quickly make judgments, remove complexity and simplify, choose the most direct and most efficient form, and also reduce the fun.
