測(cè)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(yīng)具有質(zhì)量證書，并符合現(xiàn)行規(guī)定。鋼板和附件應(yīng)有清晰的產(chǎn)品標(biāo)識(shí)。檢查是否符合設(shè)計(jì)要求。鋼板應(yīng)逐個(gè)進(jìn)行外觀檢查，其質(zhì)量應(yīng)符合現(xiàn)行的鋼板質(zhì)量標(biāo)準(zhǔn)規(guī)定。鋼板的局部減薄量、劃痕深度和實(shí)際負(fù)偏差之和不應(yīng)大于相應(yīng)鋼板的標(biāo)準(zhǔn)負(fù)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(duì)材料的外觀質(zhì)量和尺寸進(jìn)行抽查，如發(fā)現(xiàn)不合格產(chǎn)品，加倍抽查。如果復(fù)檢不合格，通知供應(yīng)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(yīng)符合設(shè)計(jì)要求并有質(zhì)量證明書，質(zhì)量證明書應(yīng)符合現(xiàn)行質(zhì)量標(biāo)準(zhǔn)《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(yàn):長寬允許偏差1.5m對(duì)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.
