                風管板材厚度、表面平整度、外形尺寸等不符合要求,板材有銹斑。

                The thickness, surface flatness, and overall dimensions of the air duct board do not meet the requirements, and there are rust spots on the board.

                選用板材時不按設計要求和施工規范進行。

                Not following the design requirements and construction specifications when selecting boards.

                (1)應按設計要求根據不同的風管管徑選用板材厚度。

                (1) The thickness of the plate should be selected according to the design requirements for different air duct diameters.

                (2)所使用的風管板材必須具有合格證明書或質量鑒定文件。

                (2) The air duct sheets used must have a certificate of conformity or quality identification documents.

                (3)當選用的風管板材在設計圖紙上未標明時,應按照施工規范實施。

                (3) When the selected air duct board is not indicated on the design drawings, it should be implemented in accordance with the construction specifications.

                濟南通風管道咬口拼接不平整,咬口縫不緊密。

                The joint of Jinan ventilation pipeline bite is uneven and the bite seam is not tight.

                風管板材下料找方直角不準確,咬口寬度受力不均勻,風管制作工作平臺不平整,風管咬口線出現彎曲、裂紋。

                The cutting of the air duct board is not accurately aligned with the right angle, the force on the bite width is uneven, the working platform for air duct production is uneven, and the bite line of the air duct is bent or cracked.

                (1)風管板材下料應經過校正后進行。

                (1) The cutting of air duct panels should be carried out after correction.

                (2)明確各邊的咬口形式,咬口線應平直整齊,工作平臺平整、牢固,便于操作。

                (2) Clearly define the bite form on each side, the bite line should be straight and neat, and the working platform should be flat and firm, making it easy to operate.

                (3)采用機械咬口加工風管板材的品種和厚度應符合使用要求。

                (3) The variety and thickness of the air duct board processed by mechanical biting should meet the usage requirements.

                風管不垂直,兩端口平面不平行,管徑變小。

                The air duct is not vertical, the two port planes are not parallel, and the pipe diameter decreases.

                制作同徑圓風管時下料找方直角不準確,制作異徑圓風管時,兩端口周長采用劃線法,直徑變小,其咬口寬度不相等。

                When making circular air ducts with the same diameter, the cutting and right angles are not accurate. When making circular air ducts with different diameters, the circumference of the two ports is marked off, resulting in a smaller diameter and unequal bite width.

                (1)下料時應用經過校正的方尺找方。

                (1) When cutting, a calibrated square ruler should be used to find the square.

                (2)圓風管周長應用計算求出,其計算公式為:圓周長=π×直徑+咬口留量。

                (2) The circumference of a circular air duct should be calculated using the formula: circumference=π × Diameter+bite allowance.

                (3)應嚴格保證咬口寬度一致。

                (3) Strictly ensure that the width of the bite is consistent.

                濟南通風管道表面不平,兩相鄰表面互不垂直,兩相對表面互不平行,兩端口平面不平行。

                The surface of Jinan ventilation ducts is uneven, with two adjacent surfaces not perpendicular to each other, two opposite surfaces not parallel to each other, and two port planes not parallel.

                下料找方不準確,風管兩相對面的長度及寬度不相等;咬口受力不均勻。

                Inaccurate cutting and square finding, resulting in unequal length and width of the two opposite faces of the air duct; Uneven force on the bite.

                (1)板材找方劃線后,須核查每片長度、寬度及對角線的尺寸,對超過偏差范圍的尺寸應以更正。

                (1) After the board is square and marked, the length, width, and diagonal dimensions of each piece must be checked. Any dimensions that exceed the deviation range should be corrected.

                (2)下料后,風管相對面的兩片材料,其尺寸必須校對準確。

                (2) After cutting, the dimensions of the two pieces of material on the opposite side of the air duct must be accurately calibrated.

                (3)操作咬口時,應保證寬度一致,閉合咬口時可先固定兩端及部位,然后均勻閉合咬口。

                (3) When operating the bite, the width should be consistent. When closing the bite, the two ends and the center can be fixed first, and then the bite can be evenly closed.

                (4)用法蘭與風管翻邊寬度來調整風管兩端口平行度及垂直度。

                (4) Use the flange and duct flange width to adjust the parallelism and verticality of the two ports of the duct.
