三分PK拾(1)现象:板材表面不平整,厚度不均匀,有明显的压痕、裂纹、砂眼、结疤和锈蚀等情况;风管平面下沉,侧面向外凸起。有明显的变形。

(1) the phenomenon: the plate surface roughness, uneven thickness, obvious indentation, crack, sand hole, scarring and corrosion etc.; duct plane convex side sink. Marked deformation.

(2)原因分析:制作风管前,没有对所用材料进行质量检查,没有测量钢板厚度。

三分PK拾(2) cause analysis: before making the duct, there is no quality check on the material used, and the thickness of the steel plate is not measured。

三分PK拾(3)防治措施:先检查材料出厂合格证书和材料质量证明,然后检查材料外观,测量钢板厚度。

(3) prevention and control measures: first check the materials, the factory certificate and material quality certification, and then check the appearance of the material, measuring steel thickness.

其次,风管翘角、扭曲及弯头角度不准确

Second, the wind pipe angle, distortion and elbow angle is inaccurate

(1)现象:矩形风管两相对平面不平行、两端面不平行,折角不平直,对角线不相等,咬口不严

(1) phenomenon: the rectangular air duct two is not parallel to the plane, the ends are not parallel, the angle is uneven, straight, the diagonal is unequal, and the bite is not strict

(2)原因分析:下料放样不准确,风管相对面两端不平行.相对面的板料长度和宽度不相等。风管的四角处咬口宽度不相等,咬口缝设置部位不对,手工咬口缝用力大小不一样,未采取相应的加固措施。

(2) cause analysis: the lofting of the material is not accurate; the ends of the relative sides of the wind pipe are not parallel; the length and width of the material on the opposite face are not equal. In the four corners of the wind pipe, the width of the bite mouth is not equal, and the setting position of the bite joint is wrong, and the size of the manual bite joint is different, and the corresponding reinforcement measures are not taken.

(3)防治措施:展开下料时,应该对每片板料的长度、宽度严格控制,以及检验对角线,使它们的偏差控制在允许范围内,下料后的板料,应该将风管相对面的两片板料重合起来,检验尺寸的准确性,板料咬口预留尺寸必须正确,以保证咬口宽度一致,咬口缝设在四角部位,手工咬口合缝时,用木锤先将咬口两端中心部位打紧.再沿全长均匀打,执行国标《通风与空调工程施工及验收规范》的有关规定。

(3) prevention measures: when feeding should be strictly controlled for each piece of sheet length, width, and the test of diagonal, so that their deviation controlled within the allowable range, the sheet material, should be relatively the two wind pipe plate material overlap, the size of the inspection accuracy of plate the bite size of material reservation must be correct, to ensure that the width of bite, bite sew in the four corners, hand bite suture, with wooden hammer first bite at both ends of the central part of matter. Then along the length of the uniform, the implementation of the relevant provisions of national standard "ventilation and air conditioning engineering construction and acceptance specification".
