Handrails are usually installed on both sides of corridors, staircases, toilets, bathrooms, etc. It is an auxiliary facility for the elderly to move, sit and lie. The installation requirements of safety handrails vary according to different use scenarios.
Corridor
The height is the most important part of corridor handrail.
In essence, the handrails of corridors and corridors should be like walking with a continuous crutch. Therefore, its height should also be designed according to this idea.
The height of the handrails should be determined by the height of the user. Measure the styloid point of the ulna, and the height of the handrails should be the same as that of the handrails.
Most people's ulnar styloid point is within 750-850mm from the ground. In Japan, the average height of the elderly is low, so the height of handrails in families is usually 750 mm. In China, or in public places, it can be raised appropriately according to the situation, such as 800 mm or more.
Therefore, the specific height of handrails installed in families depends on people. It is better not to read than to believe all books. This must be noted.
Entrance handrail
Vertical handrails shall be installed at the entrance. When ordinary people open the door, the position of the hand is about shoulder height. Therefore, the upper end of the vertical handrail must be higher than the shoulder, and the length cannot be less than 500 mm.
In fact, if you carefully observe the wall on the side of the door, you may find the trace of hand holding, which makes it easier to measure the height.
