樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)組合板(ban)(ban)(ban)是一種十分合理的(de)(de)結構(gou)方式，它能(neng)夠按其各組成部件所處(chu)的(de)(de)方位和(he)特色，充分發(fa)揮(hui)鋼材抗拉和(he)混(hun)凝土抗壓功能(neng)好的(de)(de)長處(chu)，并具(ju)有(you)(you)杰出的(de)(de)抗震(zhen)功能(neng)、施(shi)(shi)工功能(neng)。這(zhe)種結構(gou)現在被廣泛運(yun)用于國內外修建中(zhong)，但在國內大(da)都將樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)當作(zuo)模板(ban)(ban)(ban)運(yun)用，而沒有(you)(you)充分發(fa)揮(hui)樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)的(de)(de)效果。 與一般鋼筋混(hun)凝土樓(lou)板(ban)(ban)(ban)比較，樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)組合樓(lou)板(ban)(ban)(ban)具(ju)備(bei)以下長處(chu)：樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)能(neng)夠作(zuo)為現澆(jiao)混(hun)凝土的(de)(de)模板(ban)(ban)(ban)。這(zhe)樣就省掉了施(shi)(shi)工中(zhong)裝置(zhi)(zhi)和(he)撤(che)除模板(ban)(ban)(ban)等工序，然后節約了時刻(ke)和(he)勞動力;當樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)裝置(zhi)(zhi)好今后將能(neng)夠作(zuo)為施(shi)(shi)工平(ping)臺運(yun)用。

鍍鋅管批發樓承板適應主體鋼結構快速施工的要求，能夠在短時間內提供堅定的作業平臺，并可采用多個樓層鋪設壓型鋼板，分層澆筑混凝土板的流水施工。永川鍍鋅管在使(shi)用(yong)階段樓(lou)(lou)承(cheng)(cheng)板作為(wei)混(hun)(hun)凝土樓(lou)(lou)板的(de)(de)(de)受拉鋼(gang)筋，也提高(gao)了(le)(le)樓(lou)(lou)板的(de)(de)(de)剛度(du)(du)，節(jie)省了(le)(le)鋼(gang)筋和(he)混(hun)(hun)凝土的(de)(de)(de)用(yong)量。樓(lou)(lou)承(cheng)(cheng)板上(shang)面可以鋪設保溫，隔音(yin)，隔熱，隔振等材料。樓(lou)(lou)面性能充分(fen)發揮鋼(gang)的(de)(de)(de)良好(hao)的(de)(de)(de)抗拉強(qiang)度(du)(du)和(he)延性及混(hun)(hun)凝土優良的(de)(de)(de)抗壓強(qiang)度(du)(du)和(he)較大的(de)(de)(de)剛度(du)(du)。壓型(xing)板表面壓紋使(shi)樓(lou)(lou)承(cheng)(cheng)板與(yu)混(hun)(hun)凝土之(zhi)間產生大的(de)(de)(de)結(jie)(jie)合(he)力(li)，使(shi)二(er)者形(xing)成整體，配(pei)(pei)以加勁肋，使(shi)樓(lou)(lou)承(cheng)(cheng)板系統具有高(gao)強(qiang)承(cheng)(cheng)載力(li)。在懸(xuan)臂條(tiao)件下，樓(lou)(lou)承(cheng)(cheng)板僅作為(wei)性模(mo)板。懸(xuan)挑的(de)(de)(de)長度(du)(du)可根據樓(lou)(lou)承(cheng)(cheng)板的(de)(de)(de)截面特性來定。為(wei)了(le)(le)防(fang)止懸(xuan)挑板的(de)(de)(de)開裂，需在支座處(chu)依結(jie)(jie)構工程師的(de)(de)(de)設計配(pei)(pei)上(shang)負筋。
