樓承板批發樓承板組合板是一種十分合理的結構方式，它能夠按其各組成部件所處的方位和特色，充分發揮鋼材抗拉和混凝土抗壓功能好的長處，并具有杰出的抗震功能、施工功能。這種結構現在被廣泛運用于國內外修建中，但在國內大都將樓承板當作模板運用，而沒有充分發揮樓承板的效果。樂山樓承板 與一般(ban)鋼筋混凝土(tu)樓(lou)(lou)(lou)(lou)板比較(jiao)，樓(lou)(lou)(lou)(lou)承板組合樓(lou)(lou)(lou)(lou)板具備以下(xia)長處：樓(lou)(lou)(lou)(lou)承板能夠作(zuo)為(wei)現澆混凝土(tu)的(de)模板。這樣(yang)就省掉了(le)施(shi)工中(zhong)裝(zhuang)置和撤除模板等工序，然后節約了(le)時刻(ke)和勞(lao)動力(li);當樓(lou)(lou)(lou)(lou)承板裝(zhuang)置好今后將能夠作(zuo)為(wei)施(shi)工平臺運用。

樓(lou)(lou)承(cheng)板(ban)(ban)(ban)鍍(du)(du)(du)鋅(xin)(xin)(xin)首要起到防(fang)腐(fu)的(de)效果，按(an)標準組(zu)(zu)合(he)樓(lou)(lou)板(ban)(ban)(ban)與(yu)非(fei)組(zu)(zu)合(he)樓(lou)(lou)板(ban)(ban)(ban)壓型鋼板(ban)(ban)(ban)應(ying)選(xuan)(xuan)用(yong)熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)，不(bu)(bu)該選(xuan)(xuan)用(yong)電鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼板(ban)(ban)(ban)，其雙(shuang)面鍍(du)(du)(du)鋅(xin)(xin)(xin)層總含量要滿足在使用(yong)期間(jian)不(bu)(bu)致銹損的(de)要求。當作為(wei)(wei)非(fei)組(zu)(zu)合(he)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)時(shi)，鍍(du)(du)(du)鋅(xin)(xin)(xin)層含量可選(xuan)(xuan)用(yong)較(jiao)低值(zhi);當為(wei)(wei)組(zu)(zu)合(he)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)時(shi)，鍍(du)(du)(du)鋅(xin)(xin)(xin)層含量不(bu)(bu)該小于(yu)150g/m2。當為(wei)(wei)組(zu)(zu)合(he)樓(lou)(lou)板(ban)(ban)(ban)且使用(yong)環境條件較(jiao)為(wei)(wei)惡劣時(shi)，鍍(du)(du)(du)鋅(xin)(xin)(xin)層含量應(ying)選(xuan)(xuan)用(yong)上限值(zhi)或更高值(zhi)。更高的(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)要求，如(ru)雙(shuang)面鍍(du)(du)(du)鋅(xin)(xin)(xin)量為(wei)(wei)300g/m2、350g/m2或鍍(du)(du)(du)鋁鋅(xin)(xin)(xin)(5%鋁)275g/m2、300g/m2等，較(jiao)高的(de)鍍(du)(du)(du)層量使組(zu)(zu)合(he)樓(lou)(lou)板(ban)(ban)(ban)有(you)更長耐(nai)久性，同等量的(de)鍍(du)(du)(du)鋁鋅(xin)(xin)(xin)的(de)防(fang)銹蝕才能(neng)大約(yue)兩倍(bei)于(yu)一般(ban)熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)。鍍(du)(du)(du)鋅(xin)(xin)(xin)量也不(bu)(bu)是越厚越好，當鍍(du)(du)(du)鋅(xin)(xin)(xin)量較(jiao)厚時(shi)，抗剪(jian)連接件栓(shuan)釘的(de)焊(han)接質(zhi)量就很難保證，焊(han)接時(shi)，宜選(xuan)(xuan)用(yong)局部除鋅(xin)(xin)(xin)處理(li)措(cuo)施。

首先，在(zai)鋼結構樓層板(ban)(ban)(ban)(ban)中要(yao)達到(dao)耐火1.5小時，總(zong)(zong)的來說可(ke)以(yi)(yi)選擇開(kai)(kai)口(kou)板(ban)(ban)(ban)(ban)、縮口(kou)板(ban)(ban)(ban)(ban)、閉口(kou)板(ban)(ban)(ban)(ban)三(san)大類(lei)。規范上混凝(ning)土要(yao)高于(yu)開(kai)(kai)口(kou)板(ban)(ban)(ban)(ban)肋(lei)頂之上80mm，并且板(ban)(ban)(ban)(ban)底需(xu)配置板(ban)(ban)(ban)(ban)底受力(li)筋。還有一種就(jiu)是(shi)再開(kai)(kai)口(kou)板(ban)(ban)(ban)(ban)底部刷防火涂(tu)料(liao)，涂(tu)料(liao)厚度(du)大于(yu)等(deng)于(yu)15,這樣的話，只要(yao)達到(dao)構造要(yao)求高于(yu)肋(lei)頂5公分就(jiu)可(ke)以(yi)(yi)了。而縮口(kou)板(ban)(ban)(ban)(ban)和閉口(kou)板(ban)(ban)(ban)(ban)，只需(xu)要(yao)總(zong)(zong)的樓板(ban)(ban)(ban)(ban)厚度(du)大于(yu)等(deng)于(yu)110即(ji)可(ke)，但(dan)是(shi)縮口(kou)板(ban)(ban)(ban)(ban)雖(sui)然在(zai)防火方面比(bi)開(kai)(kai)口(kou)板(ban)(ban)(ban)(ban)要(yao)好。但(dan)是(shi)底部還是(shi)需(xu)要(yao)加(jia)板(ban)(ban)(ban)(ban)底受力(li)筋，而閉口(kou)板(ban)(ban)(ban)(ban)則不(bu)需(xu)要(yao)。

近期(qi)(qi)鋼(gang)價(jia)(jia)延續低迷(mi)，隨著通國規模的酷暑和旱季到(dao)來，熱鍍鋅(xin)(xin)卷(juan)(juan)板價(jia)(jia)格商(shang)場(chang)(chang)逐(zhu)漸(jian)進入需要旺(wang)季，海內(nei)鋼(gang)鐵(tie)商(shang)場(chang)(chang)或將窄幅調整。在決策層(ceng)(ceng)兩手抓制度(du)措施(shi)落實(shi)狀況、貨銀本位(wei)度(du)定向(xiang)寬松力度(du)加大的直觀層(ceng)(ceng)面利好(hao)牽(qian)動(dong)下，商(shang)場(chang)(chang)信念逐(zhu)漸(jian)趨(qu)穩(wen)(wen)，短(duan)期(qi)(qi)海內(nei)鋼(gang)價(jia)(jia)無望止(zhi)跌(die)(die)企(qi)穩(wen)(wen);另一上面，以(yi)后鋼(gang)價(jia)(jia)殺(sha)跌(die)(die)電能(neng)有余，而上漲(zhang)也仍(reng)然屏障重重。熱鍍鋅(xin)(xin)卷(juan)(juan)板價(jia)(jia)格價(jia)(jia)錢(qian)或將長期(qi)(qi)在于低位(wei)運行場(chang)(chang)面。
