Guardrail Railing Design Code

1. The guardrail railing resists horizontal load; residential design and construction enterprises should not be less than 500N/m, and in places where the flow of people is mainly concentrated, we should not be less than 1000N/n

2. The fence material should have good weather resistance and material durability. Balconies, roofs and corridors outside and wood plastics that are subject to daily spraying rain should not choose composite materials, such as easy aging, metal profile wall thickness The following requirements should be met;

：The wall thickness of the main damaged rods should not be less than 1.5m, and the general rods should not be less than 1.2mm.

Section steel: the wall thickness of the main traumatic steel bar should not be less than 3.0mm, and the general steel bar should not be less than 2.0

Ferroalloy: The wall thickness of the main damaged steel bar shall not be less than 3.5 mm. According to the anti-collision level, fences can be generally divided into Class A and Class B. Class A guardrails are reinforced and are suitable for use on particularly dangerous road sections, while Class B is used for special highways. When a vehicle collides with it, because the corrugated steel guardrail has good crash resistance and energy absorption, it is not easy to be crashed, and it can also protect the vehicle and the passengers. Foundation pit guardrail is the main form of semi-rigid guardrail for highway collision prevention. It is a continuous structure with corrugated steel guardrail panels spliced ​​with each other and supported by main columns. Hot-dip galvanizing is an effective metal anti-corrosion method, which is mainly used in metal structure facilities in various industries. The rust-removed steel parts are immersed in a molten zinc solution at about 500°C to attach a zinc layer to the surface of the steel parts to achieve the purpose of corrosion protection. The color steel fence is both rigid and flexible. It has a strong ability to absorb collision energy and collision avoidance. It has a good line of sight guidance function. It can be coordinated with the road line shape. The appearance is beautiful and coordinated. It can be used on small radius curves and is damaged. Easy to replace. The combined wave beam guardrail can be used on the narrow central partition. The standard rod should not be less than 2.0 mm

3. Railing height and spacing must comply with ((Residential Design Code)) GB50096, that is, multi-storey residential buildings and above and no overhead railing height below 1.05 meters, overhead railing fence height is not less than 1.1 meters in high-rise residential buildings, stair railing The height of the floor part of the floor maintenance of the guide rail is not less than 0.9 meters. When the length of the horizontal part of the stair railing is not less than 0.50 meters, the height of the vertical spacing railing bar is not more than 0.11 meters and 1.05 meters. Measures must be taken to prevent children from climbing.

4. In addition to clarifying the style, height and width dimensions, and different types of materials for the railing design, the guardrail should also have a detailed structural drawing of the connection and installation of the company's fixed structure, and the students should clarify the specifications, product model and wall thickness of the rod.
