木纹铝幕墙接缝有几种形式？复古The joints between wood grain curtain wall panels shall be filled with open joints. The joints of wood grain curtain wall must be sealed with sealant The air pressure balance should be paid attention to when sealant pollutes the wood grain open joint, that is, setting lining board inside to balance the wind pressure. The "aluminum curtain wall design guide manual" issued by the American architectural aluminum products association refers to: the external wall surface of the outdoor building with different air pressure, the inner air partition wall part of the air partition wall must have the structure function like a simple air tight film, and can bear the wind load load load shape pressure, that is, the wood curtain wall adopts the open joint design inner wall If the outer wall is strong enough, it will cost twice as much as the outer wall cost. When considering the use of the inner wall shear wall, attention must be paid to the mouth structure. Measures should be taken to prevent water from entering the structure due to gravity and surface tension, so as to make the wall economy
Retro aluminum curtain wall panel adopts high quality 1100, 3003, 5005 single-layer aluminum alloy plate as the base material. The surface coating can be divided into fluorocarbon spraying, powder spraying, polyester paint spraying and fluorocarbon pre roll coating. According to the processing technology, fluorocarbon spraying surface coating can be divided into two coating and one baking, three coating and one baking and three coating and two baking. The coating properties of aluminum plate surface are strictly in accordance with customer requirements, and the color can be provided by the company for customers to choose from. The coating suppliers of macro aluminum company are PPG company of USA, KCC company of Korea and other well-known companies, whose coating properties all meet AAMA (American Building Industry Association) aama2605 standard
Fastener is the main link in the installation process of aluminum curtain wall, which directly affects the connection between aluminum curtain wall and the main structure and the safety degree. Fig. 9-18 during installation, align the center lines of the fasteners in the vertical and horizontal directions, initially screw the bolts, correct the position of the fasteners, and then tighten the bolts. During the installation of aluminum veneer curtain wall, the vertical and horizontal center lines shall be aligned first, and then the electric welding shall be carried out. The length, height and quality of welding rod shall meet the requirements of structural weld.Horizontal and rigid keel assembly: before the keel is installed in place, the following connectors shall be pre assembled: galvanized steel inner sleeve connector for the joint between vertical main keels,
Wood grain curtain wall panel and fluorocarbon aluminum panel curtain wall are processed into imitation wood grain effect on the basis of aluminum veneer of metal curtain wall.
