(1)現(xiàn)象：板材表面不平整，厚度不均勻，有明顯的壓痕、裂紋、砂眼、結(jié)疤和銹蝕等情況；風(fēng)管平面下沉，側(cè)面向外凸起。有明顯的變形。

(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：制作風(fēng)管前，沒有對(duì)所用材料進(jìn)行質(zhì)量檢查，沒有測量鋼板厚度。

(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.

(3)防治措施：先檢查材料出廠合格證書和材料質(zhì)量證明，然后檢查材料外觀，測量鋼板厚度。

(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，風(fēng)管翹角、扭曲及彎頭角度不準(zhǔn)確

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

(1)現(xiàn)象：矩形風(fēng)管兩相對(duì)平面不平行、兩端面不平行，折角不平直，對(duì)角線不相等，咬口不嚴(yán)

(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：下料放樣不準(zhǔn)確，風(fēng)管相對(duì)面兩端不平行．相對(duì)面的板料長度和寬度不相等。風(fēng)管的四角處咬口寬度不相等，咬口縫設(shè)置部位不對(duì)，手工咬口縫用力大小不一樣，未采取相應(yīng)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：展開下料時(shí)，應(yīng)該對(duì)每片板料的長度、寬度嚴(yán)格控制，以及檢驗(yàn)對(duì)角線，使它們的偏差控制在允許范圍內(nèi)，下料后的板料，應(yīng)該將風(fēng)管相對(duì)面的兩片板料重合起來，檢驗(yàn)尺寸的準(zhǔn)確性，板料咬口預(yù)留尺寸必須正確，以保證咬口寬度一致，咬口縫設(shè)在四角部位，手工咬口合縫時(shí)，用木錘先將咬口兩端中心部位打緊．再沿全長均勻打，執(zhí)行國標(biāo)《通風(fēng)與空調(diào)工程施工及驗(yàn)收規(guī)范》的有關(guān)規(guī)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".
