How to make a barrier-free design for elevators in old-age buildings?

Mar 13, 2018

Due to the decline in physical function of the elderly, both the control of vision, muscles and the sense of balance of the body are obviously degraded. With the growth of age, especially for the elderly who cannot walk independently, the elevator is getting more and more. Become their only and important travel tool.

    With the rapid development of modern old-age care model and the continuous improvement of humanized appeals, the architectural design of the old-age care institutions pays more attention to the development of barrier-free design. Elevators are an important part of high-rise buildings to ensure accessibility for people with reduced mobility. The design of elevators and elevators greatly affects the ease of use of elevators, and the use of wheelchairs and emergency stretchers is also proposed for the size and detail design of elevators and elevator halls. Special requirements.

    Based on the specification of “Living Architecture Design for the Elderly” and based on the barrier-free design of elevators, He Ruiyang, in conjunction with the research and investigation of Ruihe experts, summarized the following design criteria.

    First, the design principles of accessible elevators

    1, security

    In addition to ensuring basic safety, the elevator design must be able to effectively avoid various injuries that may result from improper operation. Therefore, a reasonable elevator space and size must be required to facilitate flexible steering of the wheelchair.

    2. Applicability

    The comfort and correctness of elevators are the key needs of the public. To ensure harmony between the environment, elevators and people, there are many ways to display important information, such as overweight tones, colors and voice prompts when arriving at the floor.

    In addition, relevant designs should be carried out for specific groups of people. For example, for wheelchair users, the height of the elevator button should be set in addition to the normal height. Additional buttons for wheelchair users should be added.

    3, ease of use

    The design of the elevator should be based on the degree of importance of the information, and the information should be provided to the user according to the priority. For example, the color of the elevator floor should be different from that of the waiting hall. The elevator selection button must be distinguished from the switch button.

    Second, the "old people living building design" basic guidelines


    1. When a public building is equipped with an elevator, a barrier-free elevator must be provided.

    2. The barrier-free facilities and design requirements of the waiting hall shall comply with the following table.

Design category                         Design requirements
depthDepth of the hall is greater than or equal to 1.80m
ButtonsHeight 0.90mm to 1.1mm
Elevator door openingNet width greater than or equal to 0.90m
Display and audioClearly shows the car's up and down direction and number of floors and elevator arrivals
  1. Each floor should be installed floor sign

  2. Elevator mouth should prompt blind road

3. The barrier-free design of the elevator car should meet the following requirements.

Design categoryDesign requirements
Elevator doorOpen net width greater than or equal to 0.80m
  1. Car depth greater than or equal to 1.40m

  2. Car width greater than or equal to 1.10m

armrestThe front and side of the car should be provided with handrails 0.80~0.85m high
Layer buttonThe side of the car should be set with a selection button with braille of 0.90~1.10m
mirrorMirrors should be installed on the front side of the car at a height of 0.90m.
Display and audioThe car should be clearly displayed and reported to the floor when it is running and arriving.

     Third, the elevator and stretcher size

     After investigation and research, Ruihe found that the minimum size of a stretcher elevator car can be 1500mm×1600mm. The scoop stretcher size for common elevators is 400mm x 1850mm.

     Fourth, elevators that can accommodate stretchers

     "Containment stretcher" does not mean that a medical stretcher must be configured. The idea of an ordinary house capable of accommodating a stretcher elevator includes: transforming the stretcher; using the elevator car diagonal; widening the elevator door or offsetting the elevator door opening.

     The types of elevators that can accommodate elevators are mainly divided into the following four types:

     1, large and deep car:

2, large wide car:

3, square car:

4, backpack type car:

Fifth, elevator car floor

     The elevator floor refers to the decorative materials laid on the elevator platform. With the different types of elevator requirements, the type of floor selected is different. The following and Rui will focus on discussing the barrier-free elevator floor design of the nursing home.

     1, floor material

     (1) PVC plastic floor

     PVC plastic floor refers to the use of PVC materials produced by the Jiate floor. It is a kind of light floor decoration material, mainly energy saving, environmental protection, durability, aesthetics and other effects. It is also one of the materials used for non-slip flooring.

     (2) floor mats

     The floor mat is a flooring product that can effectively remove dust and moisture at the entrance and keep the floor clean and tidy. At the same time, it is comfortable and soundproof.

     (3) marble floor

     The marble floor is made of fired clay. It is physically stable, resistant to pressure and wear, and densely organized. It does not deform for a long time.

     2, floor pattern

     The elevator floor pattern mainly focuses on both hue and graphics. In combination with the pathological features of the decline in the resolving power of the elderly, the floor of the car and the floor of the hall should be distinguished in terms of hue and graphics so that the elderly can clearly enter and exit the elevator.

     (1) Hue

     Due to the deterioration of vision, it is not sensitive to the light in the room and can't distinguish between small things. According to the research results of LIXIL, the overall illumination of the room that makes the elderly feel comfortable is about 50-250 lux (lx). 1.5 times that of young people. Therefore, the illumination of older apartment elevators is slightly higher than that of ordinary restaurants.

     (2) Graphics

     The elevator floor adopts a relatively large and relatively stable color and pattern with the lobby, resulting in a clear contrast at the intersection of the interfaces. The boundaries of the ground can be distinguished by changing the tone and pattern of the elevator floor and the hall to change the boundaries so that the user can access the elevator.

     Sixth, summary

     In this article, HeRui Pension based on the design principles of barrier-free elevators, through the summary of design standards and precautions for barrier-free elevators, combined with the special physiological needs of the elderly, from the implementation of the specification to the detailed design, systematically elaborated The design requirements of barrier-free elevators in old-age buildings.

     As an important tool for the elderly to travel daily, elevators not only need to meet the daily travel and emergency time traffic needs, but also should take into account the special needs of the elderly in different physical conditions, highlight the humane details of the service, to ensure that the elevator can be for the elderly Traveling provides more secure services and creates a more convenient and comfortable travel experience for the elderly and people with mobility difficulties.
