The contribution of floor bearing plate in steel structure engineering is obvious to all, especially the advantages of wide application range and fast construction speed of floor bearing plate, which has established its position in the field of steel structure. Now let's talk about how to solve the quality problems in Jinan floor bearing plate construction.

1.几何尺寸偏差和运输损伤

1. Geometric dimension deviation and transportation damage

这两个问题主要出现在加工过程中，因此，在楼承板开始生产加工之前，安排人员对加工工艺、外观和尺寸进行检测，符合要求之后再开始批量生产。对于尺寸偏差超过要求的，或在运输途中受到损伤的构件，轻微损伤现场维修，损伤严重的，应进行退回返修或换新。楼承板厂家认为，这是一家负责任的企业应该承担的责任。

These two problems mainly occur in the processing process. Therefore, before the production and processing of the floor bearing plate, arrange personnel to inspect the processing technology, appearance and size, and start batch production after meeting the requirements. For components with dimension deviation exceeding the requirements or damaged during transportation, minor damage shall be repaired on site, and those with serious damage shall be returned for repair or replaced. The floor bearing plate manufacturer believes that this is the responsibility of a responsible enterprise.

2.边角板变形

2. Corner plate deformation

在运输过程中没有妥当采取保护措施是造成边角板变形的主要原因。楼承板厂家建议：在楼承板下方铺设垫板，用打包带或专门的角钢包装架捆扎，在周围做好柔性防护并且确保固定稳妥，便可防止构件之间的损伤。

The main reason for the deformation of the corner plate is that the protective measures are not properly taken during transportation. The manufacturer of the floor bearing plate suggests that: lay a base plate under the floor bearing plate, bind it with a packing belt or a special angle steel packing frame, provide flexible protection around it and ensure that it is firmly fixed, so as to prevent damage between components.

3.点焊脱开

3. Spot welding separation

这里说的“点焊脱开”是桁架筋和镀锌板连接的焊接部分，这个问题主要是由于桁架钢筋直径较粗，打弯不到位，导致虚假点焊。避免这个问题，需要从源头出发，会对桁架钢筋弯曲设备进行调试，以确保弯曲成型的准确度。

The "spot welding separation" here refers to the welding part of the connection between the truss reinforcement and the galvanized plate. This problem is mainly due to the thick diameter of the truss reinforcement and the failure to bend it in place, which leads to false spot welding. To avoid this problem, we need to start from the source and debug the truss reinforcement bending equipment to ensure the accuracy of bending and forming.

另外，还应加强焊接部分的质量检查。楼承板厂家通常的处理措施：如果是局部点焊脱开可进行现场复焊；如果情况较为普遍，就须返回处理。值得一提的是：如果点焊处的镀锌板有穿孔现象，应对穿孔部位用胶封堵，另外，考虑到是焊接电流过大的问题，因此应对施焊电流进行调试。

In addition, the quality inspection of welding parts shall be strengthened. Common treatment measures of floor bearing plate manufacturer: if it is local spot welding separation, conduct on-site re welding; If the situation is more common, it must be returned for processing. It is worth mentioning that if the galvanized sheet at the spot welding point has holes, the holes should be sealed with glue. In addition, considering the problem of excessive welding current, the welding current should be adjusted.

按照规定，材料在进场前需要进行再次复核，通常会出问题的地方，以上就是问题的相关解答了，您对此有什么内容就来我们网站http://jyjfsj.com咨询吧！
