Comments: (1) The height of the railing is determined according to the monitoring data of the national physique and the necessary safety reserves. The conventional protective height is roughly 1.05 meters at the lower part and 1.10 meters at the height; however, the public places of schools, businesses, hospitals, hotels, transportation and other buildings near the atrium are more dangerous, and the height of the pool balustrade framed glass balustrade and balcony balustrades prices is further increased to 1.20 meters; while the nursery school , The maximum protective height of the railing in the kindergarten is 1.30 meters, mainly considering the situation that infants and young children are active, easy to climb, and adults hold the baby to stand. (2) Protection measures of 0.8m or 0.9m need to be set for external windows and curtain wall windows without balconies or platforms. The main purpose is to prevent people from falling from high altitudes after the glass is impacted. The practice of adding laminated glass to the frame. "Residential Design Code" (GB50096-2011) stipulates that the mesa, horizontal pool balustrade framed glass balustrade and balcony balustrades prices and other treads that are less than 0.45m away from the floor (ground) surface are likely to cause unconscious climbing, and should not be included in the clear height of the window sill.
2. Other numbers:

(1) For the pool balustrade framed glass balustrade and balcony balustrades prices of residences, nurseries, kindergartens, primary and secondary schools and other special activity places for children, when vertical rods are used as pool balustrade framed glass balustrade and balcony balustrades prices, the net spacing of the rods should not be greater than 0.11m. (Note: refer to Article 6.7.4 of "Uniform Standard for Civil Building Design" (GB50352-2019), this article is a strong one)
(2) The protective pool balustrade framed glass balustrade and balcony balustrades prices must be constructed to prevent children from climbing, and the clear distance between the vertical members of the pool balustrade framed glass balustrade and balcony balustrades prices should not be greater than 0.11m. (Note: refer to Article 6.1.3 of "Code for Residential Design" (GB50096-2011), this article is a strong one)
(3) The clearance between the vertical members of the stair railing should not be greater than 0.11m. (Note: refer to Article 6.3.2 of "Code for Residential Design" (GB50096-2011), this article is a strong one)
2. "0.09"

(Note: Please refer to Article 4.1.9 of "Code for Architectural Design of Nurseries and Kindergartens" (JGJ39-2016) (2019 Edition), which is a strong article)
Comments: When vertical rods are used as pool balustrade framed glass balustrade and balcony balustrades prices, the clear spacing requirements of the rods are all strong strips, so special attention is required. The conventional value is 0.11 meters, but the value of nurseries and kindergartens is further reduced to 0.09 meters, mainly to prevent the head or body of infants and young children from getting stuck in the gap of the railing, causing safety accidents.
Three, you need to know a few common sense:
(1) The height of the railing should be calculated from the ground or roof of the building where it is located to the vertical height of the top surface of the railing. When the width of the bottom surface is greater than or equal to 0.22m and the height is less than or equal to 0.45m, it should be calculated from the top surface of the stepable part. . (Note: refer to Article 6.7.3 of "Uniform Standard for Civil Building Design" (GB50352-2019))
(2) Horizontal load of pool balustrade framed glass balustrade and balcony balustrades prices: The current national standard "Code for Loads of Building Structures" GB50009 stipulates that the load of horizontal thrust at the top of pool balustrade framed glass balustrade and balcony balustrades prices is 1.0kN/m. Because students are frolicing or evacuating in emergency, the number of people who squeeze and push the pool balustrade framed glass balustrade and balcony balustrades prices in a concentrated manner often exceeds 2 people/m, and the GB50099 Design Specification for Primary and Secondary Schools is increased to 1.5kN/m.
Fourth, the height of the protective railing during the construction process
The above is the height of the protective pool balustrade framed glass balustrade and balcony balustrades prices required by the building design specifications, but during the construction process, what is the protective height of the construction site at the edge or near the opening of the construction site?
The answer is: the normal value is not less than 1.2m, but there is an exception, the protective height of the elevator shaft protection door should not be less than 1.5m. The above values refer to "Technical Specifications for Safety of Construction at Heights" (JGJ80-2016).
