樓(lou)(lou)承(cheng)板(ban)(ban)組(zu)合板(ban)(ban)是一(yi)種十分(fen)合理的(de)(de)結構(gou)方式，它能(neng)夠按其各(ge)組(zu)成部件所處的(de)(de)方位和特色，充分(fen)發(fa)揮(hui)鋼(gang)材抗拉和混(hun)凝土(tu)抗壓功(gong)能(neng)好的(de)(de)長(chang)處，并具(ju)有(you)杰出的(de)(de)抗震(zhen)功(gong)能(neng)、施(shi)(shi)工功(gong)能(neng)。這種結構(gou)現在被(bei)廣泛運(yun)用于國內外(wai)修建中，但(dan)在國內大都將(jiang)(jiang)樓(lou)(lou)承(cheng)板(ban)(ban)當作(zuo)(zuo)模(mo)板(ban)(ban)運(yun)用，而沒有(you)充分(fen)發(fa)揮(hui)樓(lou)(lou)承(cheng)板(ban)(ban)的(de)(de)效果。 與一(yi)般鋼(gang)筋混(hun)凝土(tu)樓(lou)(lou)板(ban)(ban)比較，樓(lou)(lou)承(cheng)板(ban)(ban)組(zu)合樓(lou)(lou)板(ban)(ban)具(ju)備以下(xia)長(chang)處：樓(lou)(lou)承(cheng)板(ban)(ban)能(neng)夠作(zuo)(zuo)為現澆混(hun)凝土(tu)的(de)(de)模(mo)板(ban)(ban)。這樣就(jiu)省(sheng)掉(diao)了施(shi)(shi)工中裝置和撤除(chu)模(mo)板(ban)(ban)等工序(xu)，然后節約了時刻和勞動力(li);當樓(lou)(lou)承(cheng)板(ban)(ban)裝置好今后將(jiang)(jiang)能(neng)夠作(zuo)(zuo)為施(shi)(shi)工平臺運(yun)用。

近期鋼(gang)價(jia)(jia)(jia)延續低(di)迷，隨著(zhu)通國規模的酷暑和旱季(ji)到來(lai)，熱鍍鋅卷板(ban)價(jia)(jia)(jia)格商(shang)場逐漸進入(ru)需要旺季(ji)，海(hai)內鋼(gang)鐵商(shang)場或將窄幅調整(zheng)。在決(jue)策層兩(liang)手抓制(zhi)度(du)措施落實狀況(kuang)、貨銀本位度(du)定向寬松力度(du)加大的直觀層面利(li)好(hao)牽動(dong)下，商(shang)場信念逐漸趨穩，短期海(hai)內鋼(gang)價(jia)(jia)(jia)無望止跌企穩;另一上面，以后(hou)鋼(gang)價(jia)(jia)(jia)殺跌電能有余，而(er)上漲也仍(reng)然屏障重重。熱鍍鋅卷板(ban)價(jia)(jia)(jia)格價(jia)(jia)(jia)錢或將長期在于低(di)位運行場面。
