54、鋼筋密無(wú)法下料；二是泮由于鋼筋多容易產(chǎn)生離析；三是振搗不容易進(jìn)行，容易發(fā)生蜂窩、麻面或孔洞等現(xiàn)象。5） 澆搗中要注意柱模不要脹?；蚬亩?；要保證柱子鋼筋的位置，即在全部完成一層框架后，到上層放線時(shí)，鋼筋應(yīng)在柱子邊框線內(nèi)。（ 2）墻體混凝土的澆筑1）墻體混凝土澆筑，應(yīng)遵循先邊角后中部，先外墻后內(nèi)墻的順序，以保證外部墻體的垂直度。2）混凝土灌注時(shí)應(yīng)分層。分層厚度：人工振搗不大于35 cm；振搗器振搗不大于50 cm；輕骨料混凝土有大于 30 cm.3）高度在3m 以內(nèi)的外墻和內(nèi)墻，混凝土可從墻頂向板內(nèi)卸料，卸料時(shí)須在墻頂安裝料斗緩沖，以防混凝土產(chǎn)生離析。對(duì)于截面尺寸狹小且鋼筋密集的墻體，則應(yīng)在側(cè)模上

55、開門子洞，用斜溜槽投料，但高度不得大于 2m。對(duì)于高度大于3m的任何截面的墻體，均應(yīng)每隔2m 開門子洞，裝斜溜槽投料。4） 墻體上開有門窗洞或工藝洞口時(shí)，應(yīng)從兩側(cè)同時(shí)對(duì)稱投料，以防將門窗洞或工藝洞口模板擠變形。5）墻體在灌注混凝土前，須先在底部鋪510 cm厚與混凝土內(nèi)成分相同的水泥砂漿。（ 3）柱節(jié)點(diǎn)混凝土澆筑1）框架梁、柱節(jié)點(diǎn)處的特點(diǎn)：框架的梁、柱交叉的位置，稱梁、柱節(jié)點(diǎn)，由于其受力的特殊性，主筋的連接接頭的加強(qiáng)，以及箍筋的加密造成鋼筋密集，采用一般的澆筑施工方法，混凝土難以保證其密實(shí)度。5） 混凝土中的粗骨料要適應(yīng)鋼筋密集的要求：按施工圖設(shè)計(jì)的要求，采用強(qiáng)度等級(jí)相同或高一級(jí)的細(xì)石混凝土澆

56、筑。6） 混凝土的振搗：用較小直徑的插入式制動(dòng)器進(jìn)行振搗，必要進(jìn)可以人工振搗輔助，以保證其密實(shí)性。stressedt hat prom otingthe com prehe nsiverevitali zation shoul d focus one conomic construction asthe centralfocuswith,payspecialattention tograsp theimplementationoffive developmentconcepts, dee pening reformand promotingthe all-round ope ning up,e
