膜结构看台钢构件裂纹的修复方法
来源:http://www.sdcscp.com/ 发布时间:2022-07-30
膜结构看台作为一种新型膜结构建筑,其跨度较大,想要满足结构的牢固与稳定,就需要保证各个钢构件的强度。下面小编为大家整理了膜结构看台钢构件裂纹的修复方法,以供大家参考。
As a new type of membrane structure building, the membrane structure grandstand has a large span. In order to meet the firmness and stability of the structure, it is necessary to ensure the strength of each steel member. The following Xiaobian sorted out the repair methods of cracks in steel components of membrane structure bleachers for your reference.
当钢构件上出现的裂纹并不严重,还在初始阶段,应优先采用堵焊的方式进行修复,具体操作如下:
When the cracks on the steel members are not serious and are still in the initial stage, the method of plug welding should be preferred for repair. The specific operations are as follows:
1、清洗裂纹两边80mm以上范围,内板面油污至露出洁净的金属面;
1. Clean the range of more than 80mm on both sides of the crack, and the oil stain on the inner plate surface to expose the clean metal surface;
2、用碳弧气刨、风铲或砂轮将裂纹边缘加工成坡口,直达纹端的止裂孔,坡口的形式应根据板厚和施工条件按现行相关要求选用,用碳弧气刨加工坡口时,应用砂轮将坡口表面的渗碳层磨掉;
2. Use carbon arc air gouging, air shovel or grinding wheel to process the crack edge into a groove, directly reaching the crack stop hole at the end of the grain. The form of the groove should be selected according to the plate thickness and construction conditions according to the current relevant requirements. When using carbon arc air gouging to process the groove, use grinding wheel to grind off the carburized layer on the groove surface;

3、将裂纹两侧及端部金属预热至100~150℃,并在焊接过程中保持此温度;
3. Preheat the metal at both sides and ends of the crack to 100~150 ℃, and maintain this temperature during welding;
4、用与钢材相匹配的低氢或超低氢型焊条施焊,并尽可能用小直径焊条分段分层逆向施焊,焊接顺序,每一道焊完后宜立即进行锤击;
4. Use low hydrogen or ultra-low hydrogen type welding rods that match the steel for welding, and use small-diameter welding rods as far as possible for reverse welding in sections and layers. The welding sequence should be hammered immediately after each welding;
5、按设计要求检查焊缝质量;
5. Check the weld quality according to the design requirements;
6、对承受动力荷载的构件,堵焊后其表面应磨光,使之与原构件表面齐平,摩擦痕迹线应大体与裂纹切线方向垂直;
6. For members bearing dynamic loads, the surface of the members shall be polished after plug welding to make it flush with the original member surface, and the friction trace line shall be roughly perpendicular to the tangent direction of the crack;
7、对重要的结构或厚板构件,堵焊后应立即进行退火处理。
7. For important structures or thick plate components, annealing treatment shall be carried out immediately after plugging welding.
如果裂纹性质严重,已发展成为贯穿主要受力构件更界面的裂缝,它对膜结构看台的承载能力就会形成危险,这时就不应采用堵焊的方法了,而是采取加固的措施,甚至是更换整个构件。更多相关内容就来网站http://www.sdcscp.com咨询吧。
If the crack is serious and has developed into a crack through the interface of the main stressed components, it will pose a danger to the bearing capacity of the membrane structure bleachers. At this time, the method of plugging welding should not be used, but reinforcement measures should be taken, or even the whole component should be replaced.
