鋼筋原材及接頭取樣方法

2021/06/18 分類:行業(yè)論壇 2585

鋼筋送檢

鋼筋原材：同一廠別，同一爐號、同一規(guī)格、同一交貨狀態(tài)，每60t為一驗(yàn)收批，不足60t也按一批計(jì)。閃光焊接接頭：同一臺班內(nèi)由同一焊工完成的300個(gè)同級別、同直徑鋼筋焊接接頭應(yīng)作為一批。試件從成品中隨機(jī)切取6個(gè)試件。其中3根做拉伸試驗(yàn)長約500mm，冷彎試驗(yàn)2根長約350mm。

接頭：工程焊接條件：同接頭型試、同鋼筋級別300個(gè)接頭為一驗(yàn)收批。在現(xiàn)場條件下：每一至兩層樓同接頭型試、同鋼筋級別300個(gè)接頭為一驗(yàn)收批，不足300個(gè)接頭也按一批計(jì)。試件從成品中隨機(jī)切取3個(gè)試件做拉伸試驗(yàn)長約500mm。



電渣壓力焊接頭：每一樓層或施工區(qū)段中同鋼筋級別300個(gè)接頭為一驗(yàn)收批，不足300個(gè)接頭也按一批計(jì)。試件從成品中隨機(jī)切取3個(gè)試件做拉伸試驗(yàn)長約500mm。

氣壓焊接接頭：每一樓層或施工區(qū)段中同鋼筋級別300個(gè)接頭為一驗(yàn)收批，不足300個(gè)接頭也按一批計(jì)。試件從成品中隨機(jī)切取3個(gè)試件做拉伸試驗(yàn)長約500mm。

機(jī)械連接接頭：鋼筋機(jī)械連接對接頭的現(xiàn)場檢驗(yàn)按驗(yàn)收批進(jìn)行。同一施工條件下采用同一批材料的同等級、同型式、同規(guī)格接頭，以500個(gè)為一個(gè)驗(yàn)收批進(jìn)行檢驗(yàn)預(yù)驗(yàn)收，不足500個(gè)也作為一個(gè)驗(yàn)收批。對接頭的每一驗(yàn)收批，必須在工程中隨機(jī)截取3個(gè)接頭試件作抗拉強(qiáng)度試驗(yàn)。
