钢结构施工中,一个是要提高设计质量,一个是要严格施工质量标准,结合钢结构工程施工的要求,重点描述钢结构工程施工中容易出现的问题。加工制作过程中较易发生质量问题且发生后处理起来很棘手的主要是特殊工序和重要工序。一般工序发生质量问题所占的比率很小。用钢材建造的工业与民用建筑设施被称为钢结构,湛江钢结构公司认为,钢结构工程容易出现以下问题: 
    1、整体坍塌;该工序在构件加工的质量中占有重要的地位,其质量受上道工序的影响较大,所以在装配前加强过程的监控是非常的重要。 
解决方法:注意安装顺序、临时支撑务必装好; 
    2、焊缝质量不过关;该工序属于隐蔽工程,也是比较易发生质量问题的工序之一,从2010年某公司的产品质量报表统计显示,发生该工序的质量问题中:因为焊接质量导致的焊缝返修率高达80%以上,其次是由于上道工序操作不当和操作人员的技术问题而导致焊缝质量问题约占10%,这样问题属于直接影响工程质 量的主要问题,所以此类型的问题必须通过专业的检测公司运用专业的检测工具才可以检测、评判出来,一般根据焊缝内的缺陷类型分为夹渣、未溶合、气孔等。 
解决方法:需要探伤的焊缝必须由技术过硬的焊工焊接 
    3、柱脚锚栓的预埋不准确,安装不上; 
解决方法:准确测量,浇灌混凝土时固定牢固。 
    4、涂装工序。该工序也是属于隐蔽工序,对钢结构的影响小于对于建筑功能的影响。也是较易发生质量问题的工序。工序的质量问题主要表现在:构件表面的漆膜大面积脱落和局部脱落,构件表面的漆膜脱落、产生流挂现象,漆膜的厚度不够,漆膜厚度分布不均,漆膜的颜色色差较大。

In the construction of steel structure, one is to improve the quality of the design. One is to strictly control the quality of the construction, and in combination with the requirements of the construction of the steel structure, the problems which are easy to occur in the construction of the steel structure are described. In the process of manufacturing, the quality problems are easy to occur, and the main problems are the special processes and important processes. The rate of quality problems in general processes is very small. The industrial and civil building facilities built of steel are called steel structures. The Zhanjiang steel structure company believes that the following problems are likely to arise in steel structure projects.
1, the whole collapse; the process plays an important role in the quality of the component processing, its quality is greatly influenced by the upper process, so it is very important to monitor the strengthening process before the assembly.
Solution: pay attention to installation order and temporary support.
2, the quality of the weld is not to pass through; this process belongs to the concealed project and is one of the most easy to take place in the quality problems. From the statistics of the product quality report of a company in 2010, the quality problems of the process have occurred, because the welding quality caused by the weld rework rate is up to 80%, and the next is due to the improper operation of the upper process. The technical problems of the operators lead to about 10% of the quality of the weld, so the problem is the main problem that directly affects the quality of the project. So the problem of this type must be detected and judged by professional testing companies. Dissolution, stomata, etc.
Solution: welds with defects must be welded by highly skilled welders.
3. The embedment of the anchor bolt is not accurate and can not be installed.
Solution: accurate measurement. When pouring concrete, it is firm and firm.
4. Coating process. This process is also a concealed procedure, and its influence on steel structure is less than that of building function. It is also a process that is more prone to quality problems. The quality problems of the process are mainly manifested in the large area falling off and partial falling off of the surface of the component, the film falling off of the surface of the component, the phenomenon of flow, the inconsistency of the thickness of the paint film, the uneven thickness distribution of the film, and the larger color difference between the paint film.
