測量放樣步驟介紹:
Introduction to survey and setting out steps:
1.所選用的材料和附件應具有質(zhì)量證書，并符合現(xiàn)行規(guī)定。鋼板和附件應有清晰的產(chǎn)品標識。檢查是否符合設(shè)計要求。鋼板應逐個進行外觀檢查，其質(zhì)量應符合現(xiàn)行的鋼板質(zhì)量標準規(guī)定。鋼板的局部減薄量、劃痕深度和實際負偏差之和不應大于相應鋼板的標準負偏差值。
1. The selected materials and accessories shall have quality certificates and comply with the current regulations. Steel plates and accessories shall have clear product identification. Check whether it meets the design requirements. The steel plates shall be visually inspected one by one, and their quality shall meet the provisions of the current steel plate quality standard. The sum of local thinning amount, scratch depth and actual negative deviation of steel plate shall not be greater than the standard negative deviation of corresponding steel plate.
2.根據(jù)規(guī)格對材料的外觀質(zhì)量和尺寸進行抽查，如發(fā)現(xiàn)不合格產(chǎn)品，加倍抽查。如果復檢不合格，通知供應商退貨。
2. Spot check the appearance quality and size of materials according to the specifications. If unqualified products are found, double the spot check. If the re inspection is unqualified, notify the supplier to return the goods.
3.焊接材料(焊條)的選擇應符合設(shè)計要求并有質(zhì)量證明書，質(zhì)量證明書應符合現(xiàn)行質(zhì)量標準《碳鋼焊條》GB/T5117的要求。
3. The selection of welding materials (welding rods) shall meet the design requirements and have quality certificates. The quality certificates shall meet the requirements of the current quality standard carbon steel welding rods (GB / t5117).
4.鋼板尺寸檢驗:長寬允許偏差1.5m對角線之間的允許偏差為3毫米；；板材兩側(cè)直線度允許偏差為1m。
4. Dimension inspection of steel plate: the allowable deviation of length and width is 1.5m, and the allowable deviation between diagonals is 3mm;; The allowable deviation of straightness on both sides of the plate is 1m.
