Home elevators are a part of the construction and engineering field. The design utilizes a new system made up of external molds, internal molds, and through-wall bolts. The internal mold consists of internal templates, a rotating corner module, a telescoping horizontal prop group, a chassis, chassis legs, and an internal template vertical adjuster group. Both the external and internal molds are assembled using multiple fixed steel templates joined by through-wall bolts.
Currently, the smallest elevator shaft in China measures 1250mm in width and 1450mm in depth, primarily used for home elevators. A smaller observation elevator shaft is 1600mm x 1600mm, typically used for fan-shaped observation elevators in malls or villas, though the external space might appear small. Both types of elevator shafts can support a load of 320kg, which aligns with the national standard for small passenger elevators with a 320kg capacity.
Steel Structure Elevator Shaft Bottom and Structure for Home Elevators:
Many villas, during construction, do not have a dedicated elevator shaft, requiring the use of a steel structure to replace the brick and mortar walls. Another popular option now is the elevator shaft integrated with an aluminum alloy structure.
The dimensions of the steel structure elevator shaft should be determined before installation. Each elevator shaft may differ in size depending on the specific requirements and on-site conditions. Generally, there are two main types of steel structure elevator shafts: one-piece structures and partial structures.
If a steel structure elevator shaft is built specifically for the elevator, it is designed according to the shaft dimensions, choosing either H-beams or square tubes accordingly. However, attention should be given to whether the pit has a foundation column. If so, adjustments should be made for appropriate sizing.
Appropriate Dimensions for Home Elevators:
- Minimum Size for Three People
For villas, which typically house fewer residents, a minimum size sufficient to accommodate three people is typically sufficient. A common shaft size for this purpose is 1450mm x 1450mm, with a 250kg weight capacity. However, the design must still consider the structure of the shaft, including columns and walls, so a 1600mm x 1600mm space is more ideal. If the shaft is too small, the elevator cannot be installed. - Calculating by Load Capacity
When installing an elevator in a villa, the size is often calculated based on the load capacity. For villas with 3 to 4 floors and a load capacity under 400kg, the elevator shaft size can be 1500mm x 1500mm, and the top floor height should be around 2700mm. This is a standard size. For hydraulic home elevators, which are commonly used, the minimum shaft size should be 1430mm in width and 1250mm in depth, with a car size of 850mm in width and 1100mm in depth.
