山东GRC构件安装资质标准
Shandong GRC component installation qualification standard
1、GRC构件的安装要求水平平整度、垂直垂直度、整体线条、花饰成套、曲线平滑流畅、构件表面无污染、无缺陷。
1. The installation of GRC components requires horizontal flatness, vertical perpendicularity, overall lines, complete sets of decorations, smooth and smooth curves, and no pollution and defects on the component surface.
2、GRC装饰线的安装节点准确对位，防止因预埋件错位造成构件强烈扭曲就位，造成安装受力和长期变形。
2. The installation nodes of GRC decorative line shall be accurately aligned to prevent the components from being strongly twisted in place due to the dislocation of embedded parts, resulting in installation stress and long-term deformation.
3、GRC装饰线的连接点必须连接到位，不能省略。螺栓连接必须拧紧。
3. The connection point of GRC decorative line must be connected in place and cannot be omitted. Bolted connections must be tightened.
4、GRC装饰线接缝平整，接缝小于10mm。
4. The joint of GRC decorative line shall be flat, and the joint shall be less than 10mm.
5、垂直构件应避免将上构件叠放在下构件上，各段应分别悬挂安装在墙上。
5. Vertical members shall avoid stacking the upper member on the lower member, and each section shall be hung and installed on the wall respectively.
6、GRC构件安装后，应自上而下清理表面的灰尘和污渍，接缝处应饱满、平整。
6. After the installation of GRC components, the dust and stains on the surface shall be cleaned from top to bottom, and the joints shall be full and flat.
Shandong GRC member strength meets the requirements
GRC构件的预埋件包括镀锌扁钢预埋件。镀锌扁钢预埋件的规格是根据构件的重量确定的。一般镀锌扁钢的规格有：长40mm、宽30mm、厚3mm、间距500mm，扁钢钻孔用膨胀螺栓连接。这种嵌入件的形式分为外检测、内检测、直接检测、隐蔽件等多种形式。其连接方式为直接与墙体锚固或用螺栓与安装好的钢架连接。
Embedded parts of GRC components include galvanized flat steel embedded parts. The specification of galvanized flat steel embedded parts is determined according to the weight of components. The specifications of general galvanized flat steel include: length 40mm, width 30mm, thickness 3mm, spacing 500mm, and flat steel drilling is connected with expansion bolts. This kind of embedded parts can be divided into external detection, internal detection, direct detection, concealed parts and other forms. The connection method is directly anchored with the wall or connected with the installed steel frame with bolts.
GRC构件的连接方式为膨胀螺栓。当有外墙保温（苯板）时，这种连接方式通常不适合焊接。此时必须使用膨胀螺栓进行连接固定。膨胀螺栓的长度和直径实际上是由部件的重量决定的。.
GRC members are connected by expansion bolts. When there is external wall insulation (benzene plate), this connection method is usually not suitable for welding. At this time, expansion bolts must be used for connection and fixation. The length and diameter of expansion bolts are actually determined by the weight of the components
GRC构件安装时，要求所有预埋件低于外墙抹灰15~20mm。不得暴露。
When installing GRC components, all embedded parts are required to be 15~20mm lower than the external wall plastering. Do not expose.
GRC构件产品的强度不仅取决于水泥的强度，还取决于单件的表面尺寸和填料比，并由不同的筋骨支撑结构（如竹筋）的配置决定酒吧等）。
The strength of GRC component products depends not only on the strength of cement, but also on the surface size and filler ratio of a single piece, and is determined by the configuration of different rib support structures (such as bamboo bars).
GRC构件厂家会根据建筑需要进行科学的骨架配置。建筑物的连接结构为现浇混凝土结构，实际强度等级大于C20，厚度大于1.5hef（hef为有效锚固深度，不应小于50mm），当大于100mm，使用直径不小于8mm的地脚螺栓或膨胀螺栓，当不满足上述要求时，应进行结构试验或对建筑连接结构进行加固，并通过应使用成对的穿墙螺栓和锚板进行固定。
GRC component manufacturers will carry out scientific skeleton configuration according to building needs. The connecting structure of the building is cast-in-place concrete structure, with actual strength grade greater than C20 and thickness greater than 1.5hef (HEF is the effective anchoring depth, which shall not be less than 50mm). When it is greater than 100mm, anchor bolts or expansion bolts with a diameter of not less than 8mm shall be used. When the above requirements are not met, structural tests shall be carried out or the building connecting structure shall be reinforced, and shall be fixed by using pairs of through wall bolts and anchor plates.
