Safety grab bars and safety handrails, abbreviated as grab bars and handrails, are commonly used obstacle free facilities and equipment. Jinan's barrier free armrest manufacturer reminds that the grab bar armrest can be divided into two types: walking assist armrest and action assist armrest.
Walking assist handrails are generally located in walkways, stairs, and other places. Users can hold the handrails to slide forward. Handrails are tools to assist people in safe movement, such as continuous horizontal handrails installed in accessible passages.
Action assist handrails are generally located in bathrooms, bathrooms, and other places. Users tightly hold the handrails to support them, helping them stand, sit, or maintain specific postures of the body, such as the commonly seen L-shaped handrails in accessible bathrooms, fixed or folding handrails next to toilets, etc.
In practical obstacle free engineering, we have found that many handrails or grab bars are not fixed firmly enough, especially their performance in withstanding lateral forces is poor, and they can easily become loose and damaged when shaken with a little force. The reason for this is:
On the one hand, the relevant accessibility regulations are relatively general and not detailed enough, and there is also a lack of corresponding testing basis. For example, the accessibility design specifications do not provide specific numerical requirements for the load bearing capacity of grab bar handrails, and there are also relevant accessibility technical guidelines that further specify the force strength of handrails, requiring that "handrails should be installed firmly and can withstand a weight of over 100KG". However, there is no explanation for the lateral force of handrails, making it easy to overlook the requirements of handrails for lateral force.
On the other hand, design and construction personnel lack understanding of the significance of relevant accessibility standards and concepts, especially the physiological and living characteristics of disabled people, and have a weak safety awareness when installing and fixing accessible products.
In addition, compared to foreign accessible facilities and equipment, China has a relatively low level of industrialization, especially in the industrial assembly of accessible toilets and shower rooms. There are few types of accessible products, and an organic and complete industry chain of accessible products has not yet been formed, resulting in a lack of corresponding products and corresponding technical standards for the installation of accessible products.
That's all for understanding the classification of grab bars and handrails in accessible facilities. We hope you can gain some insights. For more information, please come to our website http://www.jnndjc.com Let's consult!
