Shenzhen Airport T3 Terminal
The roof system of this project is mainly composed of three parts: honeycomb with special-shaped curved surface, concave area and transition area. The technical complexity of its shape and construction is unprecedented. Difficulties including space measurement and setting out, space support positioning, space frame installation and stakeout, roof waterproofing construction, and space panel stakeout are rare in similar projects. The metal roof in the non-skylight area of the honeycomb roof adopts rigid polyurethane foam and polyurea elastic coating as the waterproof layer, and the drainage gutter is set around the honeycomb roof, and the gutter adopts a siphon drainage system. The details are as follows:
Metal Exterior Maintenance Honeycomb Roof System Design
The honeycomb roof is the design difficulty and focus of this project. There are different angles between each honeycomb plate, and the angle changes arbitrarily. In order to meet the effect of the architectural plan, the main steel skeleton adopts a steel pipe structure, and the connection between the skeleton and the support is connected by movable adjustable mechanical bolts, so it can adapt to changes in any angle. The total roof area of this project is about 230,000 square meters, and the shape is complex. The roof waterproof is the key point and the difficulty. This project adopts a mature flexible waterproof system, spraying 2mm polyurea on 20mm thick polyurethane to connect all the parts together, minimizing waterproof weak points.
The roof insulation design is to lay a layer of heat-insulating reflective foil on the inner 3-thick aluminum veneer bottom plate, and 100 thick heat-insulating rock wool on it, and the heat-insulating rock wool is a moisture-proof layer. The glass adopts double silver LOW-E hollow laminated tempered glass.
Depression area aluminum plate
The aluminum plate in the depression area adopts a double-layer ball head multi-directional adjustable casting; the first layer is from the main steel structure to the aluminum plate steel structure, and the second layer is from the aluminum plate to the aluminum plate and aluminum keel, so that the aluminum plate itself can not be divided too much, and the The construction error of the main steel structure can be eliminated.
The aluminum plate design adopts an open system with no glue joints on the surface; 100mm thick thermal insulation glass wool is made at the steel structure of the aluminum plate, and a 2mm thick galvanized steel plate is sealed on the top to ensure the thermal insulation, fire prevention and aesthetic requirements of the system. Lay a layer of heat-insulating reflective foil on the 3-thick aluminum veneer bottom plate, and spread 100-thick insulation cotton on it, and the moisture-proof layer on the insulation cotton. The glass adopts double silver LOW-E hollow laminated semi-tempered glass. The aluminum material adopts heat-insulating profiles.
