寿县合兴浅谈钢结构制作质量未达到要求

发布时间:2015-11-13 13:42:09 浏览次数:479
两倍翼缘板及腹板玫瑰焊缝必须错开200毫米以上腹板玫瑰路600毫米。但实际往往未达到上述要求。
针对以上问题,我们提出的几点改革措施:整理
板系统的H型钢尺寸必须严格控制在一个相应的H型钢最。防止牛腿备注。
严格工艺。H型钢组装时装配夹具。如果系统组立装配机器也随时检查调整。
钢板应电池很宽的玫瑰,采用埋弧焊焊接焊缝质量改善并节省时间。又省料。
断提高操作功能和参数正确的防止割缝、啃边、倒边、停止、粗糙度过大等。
除锈质量,尽量采用抛丸或冲砂处理。对照检查,油漆后接合,完成合适的摩擦系数的保证。严格控制涂料厚度不厚薄,突然突然防止背面构件<标准油漆厚度,油漆厚厚的行为拍摄过多的原因,大型m比较大的费用增加,白白浪费了。
构件排版玫瑰时闪烁的规范要求,控制好玫瑰路太短,尽量避免构件玫瑰,面板拼缝缝隙。
拼制H型钢矫正注意质量,控制角变形值和平也。
构件油漆后应显示构件中心线表示,构件20万吨以上。重点符号表示。

构件运输及地点堆放的事件时垫平,防止构件变形、损坏和污染。



Two times of flange and web weld must be staggered over 200 mm Rose Rose 600 mm web road. But the fact is often not meet the above requirements.
In view of the above problems, we put forward some reform measures: Finishing
The H type steel size of the plate system must be strictly controlled in a corresponding H type steel. Prevent bracket remarks.
Strict process. H type steel assembly fixture. If the system set up the assembly machine is also at any time to check the adjustment.
The steel plate should be used in a wide width of the rose, and the quality of submerged arc welded seam is improved and the time is saved. And save material.
Continuously improve the operation function and correct parameters, cutting edge, prevent chamfering, stop, rough etc..
Derusting quality, as far as possible the use of blasting or sand processing. Control check, after the paint is engaged, complete the appropriate friction coefficient. Strict control of coating thickness thickness, suddenly all of a sudden to prevent rear member < standard paint thickness, paint thick behavior filmed many reasons, large M is relatively large increase in the cost, wasted.
Flashes when the component layout rose specification requirements, control the rose road is too short to avoid component rose, the panel seam gap.
The system of H type steel quality control angle correction, the deformation value of peace.
Component paint should be displayed on the central line of the component, the structure of more than 200000 tons. Key symbol representation.
Material transport and storage locations when the incident pad, prevent deformation, damage and contamination.
