應(yīng)注意的質(zhì)量問題：

Quality problems needing attention:

1、欄桿活動：原因為固定件沒有安裝在牢固的結(jié)構(gòu)上，所用的膨脹螺栓的螺絲沒有擰緊，欄桿與固定件沒有焊接安裝牢固或開焊。所以在安裝固定件時，必須打眼安裝在原結(jié)構(gòu)上，如有石材鋼骨架時，可與其連接。欄桿與固定件焊接時，必須達到焊接的質(zhì)量要求，并清除焊藥。所使用的材料厚度必須符合設(shè)計要求。

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，直線段不平：在安裝過程中，必須采用激光水平儀定好高度位置，以防出現(xiàn)扶手高度不一致。每個固定點必須緊固到位分布均勻的以防出現(xiàn)扶手平面突起的現(xiàn)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.

保證質(zhì)量措施

Quality assurance measures

1．鐵藝護欄材料要求：所有鐵藝護欄材料及成品進場，必須有材質(zhì)單，質(zhì)量保證書。
