鋼筋桁架樓承板施工及安裝驗(yàn)收質(zhì)量控制1. 開卷板探:將鋼板開卷后進(jìn)入生產(chǎn)線,首行全板超聲波檢驗(yàn)。
Quality Control for Construction and Installation Acceptance of Steel Bar Truss Floor Support Plate 1 Uncoiling plate detection: After uncoiling the steel plate and entering the production line, the entire plate is first subjected to ultrasonic inspection.
2. 矯平銑邊:通過壓砧機(jī)使原來卷曲的鋼板平整,再通過銑邊機(jī)對鋼板兩邊緣進(jìn)行雙面銑削,使之達(dá)到要求的板寬、板邊平行度和坡口形狀。
2. Leveling and milling of edges: The originally curled steel plate is flattened by an anvil press, and then the two edges of the steel plate are double-sided milled by an edge milling machine to meet the required plate width, edge parallelism, and groove shape.
3. 剪切成型:在生產(chǎn)線上將鋼板沿外沿螺旋卷曲成管狀。
3. Shear forming: On the production line, the steel plate is spirally coiled along the outer edge into a tube shape.
4. 對焊切割:采用的雙面埋弧焊技術(shù)進(jìn)行預(yù)焊接,內(nèi)焊接,外焊接。將焊接成型的方管使用等離子尺切割成規(guī)范長度。
4. Butt welding and cutting: Advanced double-sided submerged arc welding technology is used for pre welding, internal welding, and external welding. Cut the welded square tube into standard lengths using a plasma ruler.
5. 目視檢查:由專業(yè)技術(shù)人員對一些基本的參數(shù)進(jìn)行檢查。
5. Visual inspection: Professional technical personnel inspect some basic parameters.
6. 超聲波探傷:對內(nèi)外焊縫及焊縫兩側(cè)母材進(jìn)行100%的檢查。
6. Ultrasonic testing: Conduct a 100% inspection of the internal and external welds and the base metal on both sides of the weld.
7. X射線探傷:對內(nèi)外焊縫進(jìn)行100%的X射線工業(yè)電視檢查,采用圖象處理系統(tǒng)以保證探傷的靈敏度。
7. X-ray inspection: Conduct 100% X-ray industrial television inspection of internal and external welds, using an image processing system to ensure the sensitivity of the inspection.
8. 打壓試驗(yàn):在水壓試驗(yàn)機(jī)上對方管進(jìn)行逐根檢驗(yàn)以保證方管達(dá)到標(biāo)準(zhǔn)要求的試驗(yàn)壓力。
8. Pressure test: Conduct a piece by piece inspection on the square tube on the hydraulic testing machine to ensure that the square tube meets the standard test pressure requirements.
9. 倒棱平頭:將檢驗(yàn)合格后的方管進(jìn)行管端加工,達(dá)到要求的管端坡口尺寸
9. Chamfering and flat head: Process the qualified square tube at the pipe end to meet the required pipe end groove size
10. 后檢查:再次進(jìn)行超聲波和X射線探傷以及進(jìn)行管端磁粉檢驗(yàn),檢查是否存在焊接問題及管端缺陷。
10. Final inspection: Conduct ultrasonic and X-ray inspection again, as well as magnetic particle inspection of the pipe end, to check for welding problems and pipe end defects.
11. 涂油打標(biāo):合格后的方管進(jìn)行涂油以防腐蝕,并根據(jù)用戶要求進(jìn)行打標(biāo)。
11. Painting and marking: Qualified square pipes should be coated with oil to prevent corrosion and marked according to user requirements.
