钢结构零件及部件加工的质量控制
Quality Control of Steel Structure Parts and Components Processing
根据甲方的要求,监理单位应派人进驻钢结构施工单位的工厂跟踪监督,其控制的要点如下:
According to the requirements of Party A, the supervising unit shall send personnel to the factory of the steel structure construction unit to track and supervise, and the key points of its control are as follows:
1、钢材的品种、规格、性能等应符合现行国家产品标准和设计要求,并进行了复验;
1. The variety, specifications, performance, etc. of steel should comply with the current national product standards and design requirements, and have been retested;
2、钢材切割面的加工应无裂纹、夹渣、分层和大小1mm的缺棱,按规范要求用放大镜检查,以及磁粉和超声控伤检查,并按切割面数10%抽查,且不少于3个;
2. The processing of the steel cutting surface should be free of cracks, slag inclusions, layering, and 1mm sized missing edges. It should be inspected using a magnifying glass according to the specifications, as well as magnetic particle and ultrasonic damage control inspection, and 10% of the cutting surface should be randomly inspected, with no less than 3 pieces;
3、淄博钢构件加工时会产生变形,为了满足要求,必须进行矫正,根据所用的材质不同,当采取热矫正时,加热温度不能超过900℃,然后应自然冷却;当采用冷矫正时,按矫正件数的10%,抽查,且不少于3个;
3. Zibo steel members will be deformed during processing. In order to meet the requirements, they must be corrected. According to the different materials used, when thermal correction is adopted, the heating temperature cannot exceed 900 ℃, and then they should be Free cooling; When using cold correction, 10% of the number of correction pieces shall be randomly checked, and no less than 3 pieces shall be used;
三、钢构件焊接中的质量控制要点
3、 Key points of quality control in steel component welding
1、焊接材料的规格、型号、性能等应符合现行国家产品标准和设计要求,质量合格证明文件和检验报告均已检查合格。该项为强制性条文,必须严格检查。
1. The specifications, models, and performance of welding materials should comply with the current national product standards and design requirements, and the quality certificate documents and inspection reports have been inspected and qualified. This is a mandatory provision and must be strictly checked.
2、焊接材料必须与母材相匹配,应符合JGJ81《建筑钢结构焊接技术规程》的规定,并按其说明进行存放或进行烘焙存放,要提供烘焙记录台帐。
2. Welding materials must match the base material and comply with the provisions of JGJ81 "Technical Specification for Welding of Building Steel Structures". They should be stored or baked according to their instructions, and a baking record ledger should be provided.
