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線條施工工藝：

1、 GRC line construction process:

工藝流程：施工準(zhǔn)備→出場(chǎng)構(gòu)建查驗(yàn)→各類鐵件、支架制作→找準(zhǔn)外墻土建基準(zhǔn)線→按GRC構(gòu)建標(biāo)準(zhǔn)定位放線→GRC構(gòu)建就位裝置→堵縫、修補(bǔ)→養(yǎng)護(hù)→分項(xiàng)驗(yàn)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.

施工辦法：

Construction method:
1、構(gòu)件出場(chǎng)查驗(yàn)規(guī)范
