    Stick Curtain Wall System

    Frame supporting curtain wall refers to facade being supported by metal frame (aluminum, steel etc.), which are the most complicated and applied type. They can be classified as double-skin, unitized, semi-unitized, stick curtain wall etc.

    Stick Curtain Wall System

    All the constituent components in embedded bracket systems, support frame systems and sheet systems, if installed on construction piece by piece successively, are called structural member type curtain wall.
    Structural member type curtain wall has the virtue of being flexible and simple on system configuration, and also highly adaptable and economic, which is especially suitable for shaped, complex building facade, such as triangular and irregular polygon curtain wall, space folding surface curtain wall, convex-concave elevation curtain wall, double-curved faces walls and so on. It flexibly adopts glass, metal plate, stone and artificial plates as its finish materials.
    Each type of structural member type glass curtain wall of Yuanda has its own unique technical advantages as well as the following common characteristics:
    ●Curtain wall components are separated by the use of non-metallic washer to avoid hard contact. Connections between transoms and mullions, mullions and mullions are movable connections with high plane deformation and aseismatic performance which are highly adjustable under the conditions of inter-level drift and temperature-induced deformation without creating additional stress and friction noise.
    ●Curtain wall embedded bracket systems can realize three-dimensional adjustment in all directions, which is easy for installation and with a strong ability to absorb construction deviation, and also the efficient and accurate installation with a sound quality can be easily achieved.
    ●It is easy and flexible for installation; and it is easy to replace, repair and maintain.

      


     

    Stick Glass Curtain Wall

    It is the structural member type glass curtain wall as its finish material. According to the frame appearance style, it can be classified into structural member type concealed frame glass curtain wall, structural member type semi-concealed frame curtain wall, structural member type exposed frame glass curtain wall, as well as structural member type exposed concealed frame mixed glass curtain wall and so on. Different system structures shall be adopted for different styles, and each style has its own unique technical characteristics.

    Frame Concealed Glass Stick Curtain Wall

    Horizontal and vertical frames of curtain wall are both invisible hidden within the decorative sheets. Glass is connected to the glass sub-frame through the structural silicone adhesive. The sub frames are fixed to the horizontal and vertical frames through mechanic connection. The main technical features of the system are as follows:
    ●Curtain wall glass is attached to the sub-frames through structural sealant. The sophisticated processes and quality assurance systems can effectively control the environment quality of plant-specific for sealant in shop, to ensure that structural sealant is of sound quality, safe and reliable.
    ●Glass sub-frame is fixed to the aluminum alloy frame through the use of special purposed lock block, screws and nuts. Measures are taken to prevent loose and ensure a safe connection and system security;
