我们知道GRC是一种以耐碱玻璃纤维为增强资料，水泥砂浆为基体资料的纤维水泥复合资料。具有很好的抗拉和抗折强度与耐性。这种资料特别适合制作装修造型和用来表现激烈的质感，一种经过造型、纹路、质感与色彩表达设计师想象力的资料。设计者可以充分利用GRC资料所特有的高抗弯、抗拉、抗剪和抗冲击强度，依据薄壳结构原理设计制作刚性曲面造型。着重资料力学与结构力学的综合运用，结合几许造型的合理性，依托曲面内的双向轴力和顺剪力承受载荷。经过曲面造型改变，丰富建筑立面装修效果;减轻结构自重，内力均匀，提高了空间全体作业性，强度高，刚度大，节约资料，经济合理。
First of all, we know that GrC is a kind of fiber cement composite material with alkali resistant glass fiber as reinforcement material and cement mortar as matrix material. It has good tensile and flexural strength and resistance. This kind of material is especially suitable for making decoration modeling and expressing intense texture. It is a kind of material that expresses the designer's imagination through modeling, texture, texture and color. The designer can make full use of the high bending strength, tensile strength, shear strength and impact strength of GRC data, and design and make the rigid surface model according to the principle of thin shell structure. This paper focuses on the comprehensive application of data mechanics and structural mechanics, combined with the rationality of several modeling, relying on the bidirectional axial force and shear force in the curved surface to bear the load. After the surface modeling change, the facade decoration effect of the building is enriched; the self weight of the structure is reduced, the internal force is even, and the whole space operation is improved, with high strength, high rigidity, data saving and economic rationality.
一、GRC线条施工工艺：
1、 GRC line construction process:
工艺流程：施工准备→出场构建查验→各类铁件、支架制作→找准外墙土建基准线→按GRC构建标准定位放线→GRC构建就位装置→堵缝、修补→养护→分项验收。
Process flow: construction preparation → site construction inspection → production of all kinds of iron parts and supports → determination of civil engineering datum line of external wall → positioning and setting out according to GRC construction standard → GRC construction in place device → joint sealing and repair → maintenance → sub item acceptance.
施工办法：
Construction method:
1、构件出场查验规范
1. Code for site inspection of components
由于构件系围外加工预制，一切，有必要确保出场构件的质量。依据构件加工企业规范，按外观和尺寸误差进行现场查验。且出场构建须有出厂合格证书，禁止运用不合格的构件。
Since the components are processed and prefabricated outside the enclosure, it is necessary to ensure the quality of the components out of the site. According to the specifications of component processing enterprises, conduct on-site inspection according to the appearance and size errors. In addition, the outgoing construction must be provided with factory certificate, and unqualified components are forbidden to be used.
