济南c型钢施工简便，广泛应用于大型厂房、场馆、超高层等领域。由于使用范围都是人流量非常大的地方，因此安全性方面是要做好的，所以就需要在工程完毕后要厂家提供有关资料证明，有什么呢？

　　Ji 'nan C steel construction is simple, widely used in large plants, venues, super high level and other fields. Because the scope of use is a very large flow of people, so the safety aspect is to do a good job, so it is necessary to provide relevant information to prove the manufacturer after the completion of the project, what is there?

　　济南c型钢工程竣工图和设计文件；安装过程中形成的与工程技术有关的文件；安装所采用的钢材、连接材料和涂料等材料质量证明书或试验、复验报告以及工厂制作构件的出厂合格证；焊接工艺评定报告、焊接质量检验报告；高强度螺栓抗滑移系数试验报告和检查记录、隐蔽工程验收记录、工程中间检查交接记录；结构安装检测记录及安装质量评定资料、安装后涂装检测资料；设计要求的c型钢试验报告。

　　Ji 'nan C section steel project as-built drawing and design documents; Documents related to engineering technology formed during installation; Quality certificates or test and reinspection reports of the steel, connecting materials and coatings used in the installation, as well as factory certificates of manufactured components; Welding process evaluation report and welding quality inspection report; High strength bolt anti-slip coefficient test report and inspection record, hidden engineering acceptance record, project inspection handover record; Structure installation inspection record and installation quality assessment data, coating inspection data after installation; C section steel test report as required by design.

　　济南c型钢的原材料控制要控制住，在两个方面有所体现：

　　The raw material control of Jinan C-section steel should be controlled, which is reflected in two aspects:

　　钢材：应详细检查钢厂出具的质量证明书或检验报告，化学成分、力学性能和其它质量要求须符合国家现行标准的规定。根据钢材质量证明书与尺寸规格表逐张检验、核对，并检查钢材表面质量、厚度、局部平面度，钢材端边或断口处不应有分层、夹渣等缺陷。

　　Steel: the quality certificate or inspection report issued by the steel mill shall be inspected in detail, and the chemical composition, mechanical properties and other quality requirements shall meet the provisions of the current national standards. Inspect and check the steel surface quality, thickness and local flatness according to the steel quality certificate and dimension specification table, steel end or fracture should not be delamination, slag inclusion and other defects.

　　焊接材料：采用的焊接材料须与本工程所使用的钢材相匹配，由于不同的生产批号质量往往存在一定的差异，应按要求分批进行抽查。焊条、焊剂要保管得当，不得受潮，否则不仅影响操作的工艺性能，而且会对接头的理化性能造成不利影响。焊接材料放置时间过长或受潮后要重新进行焊接试验。

　　Welding materials: the welding materials used shall be matched with the steel used in the project. Due to the quality difference of different production batches, spot check shall be carried out in batches as required. The electrode and flux should be kept properly and not be affected by moisture, otherwise it will not only affect the process performance of the operation, but also adversely affect the physical and chemical properties of the joint. The welding test should be repeated after the welding material has been placed for too long or become damp.

　　c型钢工程的验收，是在c型钢的全部或空间刚度单元部分的安装工作完成后进行。这项工作的进行不仅可以检验施工质量，还可以看出施工团队的规范，因此在以后的验收过程中我们应该准备好以上资料。更多内容就来jyjfsj.com咨询吧。

　　Acceptance of c-section steel works shall be carried out after the installation of all or part of the spatial stiffness elements of C-section steel. This work can not only test the quality of construction, but also see the specifications of the construction team, so we should be ready for the above information in the later acceptance process.
