Introduction to balcony guardrail styles

With the increasing development of science and technology, the technical content of balcony guardrails has become higher and higher. Its service life, firmness, decorative effect, etc. have all been greatly improved compared to before. Below, the editor brings you several styles of balcony guardrails that are more common in daily life. Let’s take a look at them together.

Common styles of balcony guardrails

1. Wrought iron balcony guardrails

Wrought iron balcony guardrails feel more classical, with greater changes, more patterns, and older styles. With the promotion of modern architecture, the use of iron balcony guardrails has been temporarily reduced. This is a trend in society.

2. Aluminum alloy balcony guardrail

Aluminum alloy guardrail is one of the latest guardrail materials. Aluminum alloy is famous for its unique advantage of "not rusting", and has gradually become used in major buildings. Balconies are a place where children often move, and the safety of guardrails is still very important. After the surface of the aluminum alloy guardrail is powder sprayed, it will not rust, produce light pollution, and can stay new for a long time; the new cross-welding process is used between the tubes to make it safer. Light weight and impact resistant (aircraft are all made of aluminum alloy materials); aluminum alloy guardrails have become the main product of construction abroad, and the use of this product in China is also increasing year by year.

3. PVC guardrails

PVC balcony guardrails are mainly used for isolation and protection of balconies in residential areas; they are installed using socket-type connectors, which can greatly increase the installation speed. The connection makes it easy to install the guardrail at any angle and in different directions on slopes or uneven ground. It is harder than wood, more elastic and has high impact resistance than cast iron, and has a long service life; the service life is more than 30 years; feel Delicate, green and environmentally friendly, with simple and bright features, it can embellish the appearance of the building and make the environment more warm and comfortable.

Safety standards for balcony guardrails

1. The mechanical properties of balcony guardrails should comply with the following table: horizontal load (N/m) vertical load (N/m) impact performance of soft heavy objects 500 (residential building) 1000 (public building) 5002000 The deflection deformation of the cross bar should not be greater than 1/120 of the length of the cross bar, and each structural member should not be damaged. Each component will not fall off, break, or undergo permanent deformation that affects use.

2. The height of balcony guardrails should not be lower than 1.05m when the ground floor, multi-storey residential buildings or the air height is less than 24m; when the mid-rise, high-rise or air height is more than 24m, it should not be lower The height of the protective railings of balconies and roof platforms in kindergartens, primary and secondary schools and special activity places for children should not be less than 1.20m.

3. The balcony railings should be designed to prevent children from climbing, and the vertical spacing between railings should not be greater than 0.11m.

4. Balcony railings in residences, nurseries, kindergartens, primary and secondary schools and special activity places for children must adopt a structure to prevent children from climbing. When vertical rods are used as railings, the net spacing of the rods must not be Should be greater than 0.11m.

5. In cultural and entertainment buildings, commercial service buildings, sports buildings, garden landscape buildings and other public buildings that allow children to enter activities, when vertical rods are used as balcony railings, the rods The clear distance between pieces should not be greater than 0.11m.

6. The height of the balcony railing should be calculated from the vertical height of the floor or roof to the top surface of the railing handrail. If there is a stepable part at the bottom with a width greater than or equal to 0.22m and a height less than or equal to 0.45m, it should be calculated from Calculated from the top surface of the stepable part.

7. The balcony railing structure must be strong and safe. When adding a flower pond to the railing, the problem of water leakage from the flower pond must be solved. It is possible that anti-fall measures must be taken where flower pots are installed.

Safety knowledge and common sense of building balcony guardrails

1. Verandahs, inner patios and upper roofs are generally straight for traffic and evacuation, and the flow of people is concentrated, especially in emergencies. Crowding is likely to occur under such circumstances, so the height of the railings in the air should be safe. According to my country's national standard GB100000---88 (Chinese adult human body size) data, the height of the center of gravity of a man's human body in an upright state is 1006.80mm. Wearing shoes The height of the rear center of gravity is 1006.80MM 20MM=1026.80MM, so the minimum safety coverage for the railing is determined to be 1.05M.

2. For mid- to high-rise and high-rise residential buildings, people will feel fear when they climb up or look down from the sky, which will lead to insecurity. Properly raising the height of the railings will increase people’s psychological sense of security. , so the requirements for multi-storey residential buildings are 0.5m higher than those on the ground floor, that is, it should not be less than 1.10m. The starting point of the railing should be calculated from the stepable part of the lower part of the railing. To ensure a safe height, three-story residential buildings are above ten floors, so According to the survey, multi-story residences are more affected by the wind than those on the ground floor. Due to the severe cold and cold weather in areas with cold wind and snow, high-rise residences are all made of closed verandah type (with windows on the wall and exterior walls). or all enclosed with glass windows); for more special cities, such as Shanghai, because the winter is very cold and windy and rainy, the urban design standards also stipulate that enclosed verandahs are also provided.
