quality standard

1、扶栏和扶手的制作应与安装所使用材料的材质、规格数量等应符合设计要求及国家标准的有关规定。

1. The fabrication of handrails and handrails shall be in accordance with the design requirements and relevant provisions of national standards.

2、扶栏和扶手的造型、尺寸及安装位置应符合设计要求。

2. The shape, size and installation position of handrails and handrails shall meet the design requirements.

3、扶栏和扶手安装预埋件的数量、规格、位置以及扶栏与预埋件的连接节点应符合设计要求。

3. The quantity, specification and position of embedded parts installed on handrails and handrails, as well as the connection node between handrails and embedded parts, shall meet the design requirements.

4、扶栏高度、栏杆间距、安装位置必须符合设计要求。扶栏安装必须牢固。

4. The height, spacing and installation position of handrails must meet the design requirements. Handrails must be firmly installed.

5、扶栏和扶手转角弧度应符合设计要求，接缝严密平整，表面光滑，色泽一致。不得有裂缝、翘曲及损坏。

5. The angle radian of handrail and handrail shall meet the design requirements, with tight and flat joints, smooth surface and consistent color. There shall be no crack, warpage and damage.

应注意的质量问题：

Quality problems needing attention:

1、栏杆活动：原因为固定件没有安装在牢固的结构上，所用的膨胀螺栓的螺丝没有拧紧，栏杆与固定件没有焊接安装牢固或开焊。所以在安装固定件时，必须打眼安装在原结构上，如有石材钢骨架时，可与其连接。栏杆与固定件焊接时，必须达到焊接的质量要求，并清除焊药。所使用的材料厚度必须符合设计要求。

1. Handrail movement: the reason is that the fixed parts are not installed on a firm structure, the screws of the expansion bolts used are not tightened, and the handrail and the fixed parts are not firmly installed or welded. Therefore, when installing the fixed parts, they must be drilled and installed on the original structure. If there is a stone steel framework, it can be connected with it. When the handrail is welded with the fixed parts, the welding quality requirements must be met, and the welding flux must be removed. The thickness of materials used must meet the design requirements.

2、扶手高度不一致，直线段不平：在安装过程中，必须采用激光水平仪定好高度位置，以防出现扶手高度不一致。每个固定点必须紧固到位分布均匀的以防出现扶手平面突起的现象。

2. Inconsistent height of handrail and uneven straight-line section: during installation, the height position must be determined with a laser level to prevent inconsistent height of handrail. Each fixed point must be fastened in place and evenly distributed to prevent the protrusion of the handrail plane.
