The main functions of GRC panel fasteners are as follows:

a. 为了板和建筑物的使用寿命，把面板固定在建筑物上。

a. The panels are fixed to the building for the service life of the slab and the building.

b. 允许在单板之间或板与支撑结构之间产生平直位移和旋转位移，而仍可保持接缝处的防水性。

b. It is allowed to produce straight displacement and rotation displacement between veneers or between slabs and supporting structure, while still maintaining the waterproof property of joints.

c. 提供足够的调节量以满足结构偏差和上述（b）中预先考虑到的位移。

c. Provide sufficient adjustment to meet the structural deviation and the displacement pre considered in (b) above.

d. 使GRC构件中的应力集中现象较小化，保持在所有不利条件（冲击、振动、风、火等）下支撑结构和约束的完整性。

d. The results show that the stress concentration in GRC members is reduced, and the integrity of supporting structure and constraints is maintained under all adverse conditions (impact, vibration, wind, fire, etc.).
              

e. 提供GRC构件面板在制造、装卸和安装过程中的起吊件。

e. Provide lifting parts for C panel of GR component during manufacturing, loading, unloading and installation.

f. GRC面板上的固定件在应在尽可能大的范围内分布，可保证力的传递。

f. The fixings on the GRC panel should be distributed as far as possible to ensure the transmission of force.

g. 在板的底部设置支撑，可充分利用GRC的强度性能，在板的上部和底部都设置支撑，可限制水平位移。对（b）条中的位移进行量化是困难的，但是为了设计、安装和密封接缝，可对位移的大小和方向进行保守的估计。

g. Setting supports at the bottom of the slab can make full use of the strength performance of GRC. Setting supports at the top and bottom of the slab can limit the horizontal displacement. It is difficult to quantify the displacement in (b), but in order to design, install and seal joints, the magnitude and direction of displacement can be estimated conservatively.
