The physical factory of galvanized and plastic-sprayed combined bridge guardrails has novel styles. Longbang Traffic Facilities
The physical factory of galvanized and plastic-sprayed combined bridge guardrails has novel styles. Guanxian Longbang Traffic Facilities Co., Ltd.'s steel truss bridge guardrails use the truss chords as supports, and the nodes of the welded rectangular steel pipes are fully penetrated and inspected by ultrasonic testing. The weight of the aluminum alloy honeycomb panel is only 1/3 of that of the steel plate. The stainless-steel hinge allows a temperature expansion and contraction of ±20 mm, and the drip eaves at the bottom guide the rainwater away from the welds. The shared pedestrian and non-motor vehicle guardrails of municipal bridges need to balance the passage needs of pedestrians and non-motor vehicles. Usually, a three-beam structure is adopted. The bottom beam is 30 cm away from the ground to prevent bicycle wheels from getting stuck. The middle beam is at a height of 60 cm for people to lean on when pushing a cart, and the top beam is 1.1 m high to ensure the safety of pedestrians. The guardrail posts adopt a variable cross-section design, with the bottom width of 12 cm gradually tapering up to 8 cm, which not only saves materials but also enhances the sense of stability. In the bus stop area, the guardrail protrudes outward by 1.5 m to form a bay-style docking space, and the protruding section of the guardrail is changed to an openable type for the convenience of temporary opening when the bus enters the station. All corners are polished into a fillet with an R of 20 mm to prevent sharp edges from scratching pedestrians' clothes or vehicles.
The physical factory of galvanized and plastic-sprayed combined bridge guardrails has novel styles. Guanxian Longbang Traffic Facilities Co., Ltd.'s airport apron guardrails are made of foam aluminum with a density of 0.4 g/cm³ and a compressive strength of 5 MPa. After impact, it will be crushed into fine particles. The glass fiber reinforced plastic posts painted with orange high-brightness reflective paint will have brittle fractures. The quick-release ground anchors are convenient for relocation to ensure safety. The guardrails of landscape arch bridges are often designed in an arc shape that echoes the lines of the arch ring. The forged iron guardrails form decorative patterns such as vines and waves through manual bending, combining classical charm with modern craftsmanship aesthetics. The structural stress of this type of guardrail needs to specially consider the influence of horizontal thrust on the arch springing. Therefore, a reinforced post is set every 6 m, and its cross-sectional size is 50% larger than that of ordinary posts. The surface treatment adopts the process of hot-dip galvanizing and electrostatic spraying. 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 theme of the bridge. At the top of the arch, the height of the guardrail is appropriately reduced to 1.2 m to ensure the viewing field, but the safety against falling is compensated by increasing the density of the balusters to 10 per meter.
The physical factory of galvanized and plastic-sprayed combined bridge guardrails has novel styles. Guanxian Longbang Traffic Facilities Co., Ltd.'s cross-sea bridge guardrails adopt triple anti-corrosion: 120 microns of thermal sprayed aluminum, 80 microns of micaceous iron oxide, and 60 microns of polyurethane fluorocarbon, with a total film thickness of more than 260 microns. A rubber water stop is added in the splash zone. The inner cavity of the post is filled with polyurethane foam to prevent condensed water, and a removable inspection cover is set on the top. The river guardrail beside the ancient city wall ruins needs to be coordinated with the style of the city wall. City-brick-colored clay balusters are used, and the surface is aged to imitate the texture of the ancient city wall. The clay balusters are fired at a temperature of 1200 °C, with a compressive strength of 50 MPa and a water absorption rate of ≤ 8%. The shape of the balusters imitates the stone balusters of the Ming Dynasty. The balustrade panels are carved with scroll grass patterns, and the capitals of the posts are lotus seats. The traditional mortise and tenon structure is used during installation, and tung oil mortar is used for caulking. The foundation of the guardrail is hidden underground without destroying the style of the ruins. Each clay baluster has an antique mark, blending in perfectly with the ancient city wall.
