Customized processing of Q235 landscape overpass guardrails by the physical factory of Longbang Traffic Facilities
Customized processing of Q235 landscape overpass guardrails by the physical factory of Guanxian Longbang Traffic Facilities Co., Ltd. The intelligent bridge guardrails are integrated with fiber Bragg grating strain gauges with an accuracy of ±1 microstrain, and the acceleration sensors can identify the impact position. When the temperature and humidity monitoring exceeds 80% and lasts for 24 hours, an early warning will be triggered. The data is transmitted to the cloud via 4G, and the solar power supply can last for 7 days without sunlight. Each column of the river channel QR code guardrail is inlaid with a stainless - steel QR code nameplate. By scanning the code, detailed information of the river section can be obtained, including: the name and phone number of the river chief, water quality indicators, historical water levels, introductions of surrounding scenic spots, rescue phone numbers, etc. The background management system can update the content and issue flood prevention warnings, activity notices, etc. The QR code is laser - engraved with a weather resistance of over 10 years. This smart guardrail has opened up an information interaction channel between people and the river, enhancing the public's enthusiasm for participating in river protection. At present, it has been promoted in many places across the country, with a cumulative installation of over 100,000 pieces.
Customized processing of Q235 landscape overpass guardrails by the physical factory of Guanxian Longbang Traffic Facilities Co., Ltd. The railway guardrails are 1.8 meters high and use welded mesh sheets. The wire diameter is 5 mm and the aperture is 75×150 mm. The column spacing is 3 meters and they are hot - dip galvanized. A barbed wire roller cage is added on the top to prevent climbing, and the bottom is buried 50 cm deep to prevent crawling under. The European classical landscape guardrails are represented by wrought - iron art, with hand - forged patterns such as scrollwork and rose branches. Each piece is a work of art. The wrought - iron components are made of Q235 low - carbon steel. They are heated to 1000 degrees Celsius and then hand - forged into shape, and then quenched and tempered to improve toughness. The surface treatment is hot - dip galvanizing plus multiple layers of paint. The primer is zinc - rich, the intermediate paint is micaceous iron oxide, and the topcoat is alkyd enamel. The total thickness is 200 microns. The guardrail is 1.3 meters high, and the top of the column is decorated with a crown or flame shape. This kind of guardrail shows aristocratic qualities and is commonly seen in high - end villas and manors.
Customized processing of Q235 landscape overpass guardrails by the physical factory of Guanxian Longbang Traffic Facilities Co., Ltd. The primary function of the river channel guardrails is to prevent falling into the water while meeting the requirements of flood discharge. The net height on the riverside side is not less than 1.2 meters, and the distance from the bottom to the ground does not exceed 15 cm. The vertical rod spacing is 11 cm and the horizontal rod spacing is 20 cm. When the flow velocity exceeds 2 m/s, the foundation is deepened to 1 meter below the riverbed. The guardrails of landscape arch bridges are often designed in an arc shape that echoes the lines of the arch ring. The forged wrought - iron guardrails form decorative patterns such as vines and waves through hand - bending, combining classical charm with modern craftsmanship aesthetics. The structural stress of this kind of guardrail needs to specially consider the influence of horizontal thrust on the arch springing. Therefore, a reinforced column is set every 6 meters, and its cross - sectional size is 50% larger than that of ordinary columns. The surface treatment adopts the hot - dip galvanizing plus electrostatic spraying process. The primer is zinc - rich paint, and the topcoat is acrylic polyurethane. The color can be customized to bronze, antique bronze, or white according to the bridge theme. At the arch crown, the height of the guardrail is appropriately reduced to 1.2 meters to ensure the viewing field, but the safety of fall prevention is compensated by increasing the density of the railings to 10 pieces per meter.
