Discussion on the Design and Decoration Process of GFRC Panel Curtain Wall

Abstract: With the global energy crisis becoming more and more serious, in order to implement the national policy of environmental protection and energy conservation and to safeguard the sustainable development strategy of the national economy, the curtain wall surface GRC board is thin, light, rich in shape, arbitrary in size, easy to draw, With no fussiness and other characteristics, GFRC panel curtain wall panels as building curtain wall decorative panels is an ideal material for building energy conservation. In this paper, combining with the practice of the construction of the second phase of the building curtain wall project of the 2010-B-48 canal, the material characteristics of the GRC board are systematically introduced, and some ideas and methods for product design, manufacturing, installation and surface effects are expounded.

GFRC curtain wall full name is GlassFiberReinforcedConcrete (alkali-resistant to 1000-dimensional reinforced cement). The design and use of the GRC board is based on the industry standard "Glass-Fiber Reinforced Cement Exterior Wallboard" (JC/T1057-2007). Compared with the traditional curtain wall system, the GRC panel curtain wall system greatly enriches the language of building facades, and has a wider range of applications. It is more simple, firmer, and has enhanced safety performance. The advantages in environmental protection and energy saving are very prominent. Due to the diversity of external textures, colors, and specifications, it provides more artistic features for building appearance and increases urban charm.

In the product structure, the glass fiber in the material breaks the wire even after it acts as a flexible reinforcing bar, and it satisfies the safety after accidental destruction. The water rate of the GRC plate is less than 6%. The inspection report of materials in previous works shows that the material is 4% to -5%. If the surface of the material is treated with photocatalyst, the water absorption rate can also be reduced. The flexural strength of the GRC plate is greater than that of the GRC plate. 18Mpa, impact strength greater than 3KJM2, can meet 25 times Chen Rong cycle experiment. A variety of glass fiber reinforced cement composite material manufacturing processes, such as spray process, premixed spray process, pre-mixed pouring process, injection molding process, cloth network process, winding process. Among them, the spraying process is the earliest and the most used method for manufacturing GRC board products, including manual spraying and automatic spraying.

For example, the design concept of the canal landscape project with the second phase of the canal project was designed by Shanghai Dianshi Investment Consulting Co., Ltd. When they communicated to us at the time, it was such a conception that the entire building deconstructed the form of the Parisian building, which lies in the law of Europe. Cylindrical and wall ornaments are geometrically restored in an abstract form of “neoclassicism,” and pillars and walls of the building are unified – with a white color, they have the effect of clear water coagulation. We consider using stone to reflect the color of this building. Due to the complex shape, the stone is glued with white seams, which is easy to stick to gray, and white stone is difficult to purchase and can not guarantee the color difference. Imagine considering an open stone curtain wall. Due to the open stone waterproof layer and the keel imitation, the cost is also high. Finally, through the expert program demonstration meeting, consider the use of GRC board materials to express the final creative ideas, the specific implementation of the first inspection similar finished Engineering and GRC board manufacturers, to do a live visual model to confirm the design program.

The geometrical reduction of columns and wall decorations is presented in abstract form as “neoclassicism”. The architectural pillars and walls are all in white color, and they have the effect of clear water coagulation. We consider using stone to reflect the color of this building.
