The duplex building is very popular for us. The duplex building is a choice for many people when buying a house, because it uses a large space to make it comfortable to live. The duplex building is very good in the layout of the area. The kitchen and living room will be arranged on the lower floor, and the bedroom study will be arranged on the upper floor. This design is the most reasonable. However, the duplex building also has some shortcomings, that is, the problem of going up and down the building. If there are elderly people or pregnant women in the family, this problem will be very prominent. At this time, it is more troublesome to lift things up and down the stairs. Based on the above shortcomings, many people choose to install a "home elevator", which is very convenient to use. Which type of driving method is installed in the duplex building? First, hydraulic home Villa Elevator (excluding hydraulic lift) Because hydraulic elevators do not need to dig pits, they can be installed in duplex buildings and stacked villas. However, because of oil spills polluting the environment and wasting a lot of electricity, it is not in line with the development concept of environmental protection and energy saving in modern elevator industry. And most of them are used for freight elevators or special elevators with large tonnage, and hydraulic household villa elevators have been rarely used for home elevator design. Second, traction home villa elevators (including steel belt elevators and strong drive elevators) Traction home villa elevator is suitable for installing single-family villas and self-built houses, but it needs to dig pits, pits are used to place buffers, and some small manufacturers actually do not install buffers or install a plastic in order to reduce the pit depth. of. The elevators for household villas are not suitable for installation in duplex buildings. The size of the elevators is large. The elevator itself is bulky. In case the balance block (weight) blocks the floor, most floors can not afford it and may damage. Floor structure. Third, imported screw elevator The screw elevator originated in Europe and is ideal for duplex buildings and stacked villas. In European countries, mainly villas with more than two floors, which is one of the reasons why screw elevators are used more in Europe than in China. Why is the imported screw elevator suitable for installation in the duplex building? 1. The safety of the screw elevator is higher than other driving methods, and the unique occlusion structure can ensure that the ladder will never fall. 2. The civil construction requirements are low. Due to the unique driving method, the screw-type home elevator does not need to dig the bottom pit, so it can be installed in the case of civil engineering wells, stairs, in the middle of the wall, even in the high-rise duplex building. 3, the volume is light. The imported screw elevator adopts aviation-grade aluminum profiles and comes with an integrated aluminum alloy shaft. 4. Small footprint. The screw elevator has no counterweight, no car, no machine room, no top height requirement, small size and less space. 5. The structure is simple and flexible. One of the four faces of the screw elevator shaft is the equipment surface, which can open the door on three sides to meet the installation environment of different floors inside the villa. In addition, the lift height of the screw elevator is limited, suitable for general private home installation below 6 floors; the price of imported screw elevator is relatively high, so I hope everyone can choose according to their needs.
