Protective railings for construction

The height of protective railings shall not be less than 1200mm.

1050mm is the reference height of the railing.

The protection height of the railing is mainly determined according to the stability of the center of gravity of the human body and the psychological requirements. The factor considered is safety, followed by aesthetics and economical application.

From the perspective of safety, the protective height of the railing should exceed the height of the center of gravity of the human body, to avoid falling accidents due to the outward movement of the center of gravity when people close to the railing.

For civil buildings, the protective height of the guardrail with a free height of 24m and below shall not be less than 1.05m, and the protective height of the guardrail with a free height of more than 24m shall be increased to 1.10m.

The public places of schools, businesses, hospitals, hotels, transportation, and other buildings near the atrium are more dangerous, and the height of protective railings is further increased to 1.20m.

For nurseries, kindergartens take into account the adults hold Infants and toddlers standing when the human body's center of gravity increases, as well as infants and toddlers' poor security awareness, ease to move, ease to climb, the height of its protective railing increased to 1.30m.

For industrial buildings, the protective height of the railings at a height of 20m and below is not less than 1.05m, and the height of the protective railings at a height above 20m is increased to 1.20m.

For windows or glass curtain walls, the height of the guardrail is reduced to 0.90m, which is determined according to the stability of the center of gravity of the human body and psychological requirements. First of all, standing in front of the window does not have the obvious dizziness of standing in front of the balcony, and secondly, the existence of the window limits the range of the human body's outward tilt.
