提高冷弯薄壁钢檩条的施工质量,首先须使用合格的原材料。通过采取实用的工艺方法,来消除檩条制作的质量通病,檩条成孔位置、除锈防腐、变形校正是关键。檩条出厂运输装卸和堆存保管,采取简易包装箱形式的措施,达到成品保护。采取提高墙架柱、屋面梁安装位置的精度,达到提高檩托板与檩条连接孔的准确性,安装火割扩孔成因及后果分析,揭示其危害性。设计应考虑檩条安装简便、质量可靠和适合国情的连接方式,做好檩条安装上道工序质量,来消除安装质量通病。完善上述方面的措施,即可最大限度减少施工质量通病,达到理想的檩条施工效果。
To improve the construction quality of cold-formed thin-walled steel purlin, first of all use qualified raw materials. By adopting a practical process, to eliminate the general quality of purlin production, purlin position into the hole, rust corrosion, deformation correction is the key. Sliver factory shipping unloading and storage custody, take the form of a simple box to achieve the finished product protection. To improve the accuracy of wall column and roof girder installation position, to improve the accuracy of pallet and purlin connection holes, fire reaming causes and consequences of installation to reveal the dangers. Design should take into account the purlin installation is simple, reliable and suitable for the national conditions of the connection, do purlin installation procedure quality, to eliminate installation quality problems. Improve the above measures, you can minimize the common problems of construction quality, to achieve the desired effect of purlin construction.
