樓(lou)承板(ban)(ban)(ban)(ban)(ban)組合(he)(he)板(ban)(ban)(ban)(ban)(ban)是一種(zhong)十分合(he)(he)理的(de)(de)(de)結構(gou)方式，它能(neng)夠按其各組成部(bu)件所(suo)處的(de)(de)(de)方位和(he)(he)特色(se)，充分發揮(hui)鋼材抗拉和(he)(he)混凝土抗壓功能(neng)好的(de)(de)(de)長(chang)處，并具(ju)有(you)杰出(chu)的(de)(de)(de)抗震功能(neng)、施工功能(neng)。這種(zhong)結構(gou)現在被(bei)廣泛運(yun)用于(yu)國內外修建中，但在國內大都將(jiang)樓(lou)承板(ban)(ban)(ban)(ban)(ban)當(dang)作(zuo)(zuo)模(mo)(mo)板(ban)(ban)(ban)(ban)(ban)運(yun)用，而(er)沒(mei)有(you)充分發揮(hui)樓(lou)承板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)效果。 與一般(ban)鋼筋混凝土樓(lou)板(ban)(ban)(ban)(ban)(ban)比較，樓(lou)承板(ban)(ban)(ban)(ban)(ban)組合(he)(he)樓(lou)板(ban)(ban)(ban)(ban)(ban)具(ju)備(bei)以下(xia)長(chang)處：樓(lou)承板(ban)(ban)(ban)(ban)(ban)能(neng)夠作(zuo)(zuo)為(wei)(wei)現澆混凝土的(de)(de)(de)模(mo)(mo)板(ban)(ban)(ban)(ban)(ban)。這樣(yang)就省掉了施工中裝置和(he)(he)撤除模(mo)(mo)板(ban)(ban)(ban)(ban)(ban)等工序，然(ran)后節約了時刻和(he)(he)勞(lao)動力;當(dang)樓(lou)承板(ban)(ban)(ban)(ban)(ban)裝置好今后將(jiang)能(neng)夠作(zuo)(zuo)為(wei)(wei)施工平臺運(yun)用。

熱鍍鋅鋼管批發樓承板的使用是需要安裝的，那么如果要安裝就要選擇合適的小配件，焊后栓釘高度大于壓型鋼板波高30MM(留意挑選樓板的類型);栓釘頂面混凝土保護層不小于15MM(留意樓板總厚度)直徑不宜大于19MM。寧夏攀華熱鍍鋅鋼管樓(lou)承板栓釘類型有ф8、ф10、ф13、ф16、ф19、ф22、ф25，栓釘一般在鋼(gang)結構修建中,遍及使(shi)用在柱腳(jiao)和樓(lou)板中,一般剛(gang)度(du)要(yao)求高的(de)(de)柱腳(jiao)都選(xuan)用鋼(gang)柱內(nei)伸至混凝土(tu)中，鋼(gang)柱埋入混凝土(tu)的(de)(de)部位四周(zhou)均布(bu)栓釘。樓(lou)承板輕鋼(gang)結構常用厚度(du)為0.8mm,1.0mm，1.2mm,荷載較大的(de)(de)情況下會用到1.5mm。一般需要(yao)用栓釘與(yu)鋼(gang)梁銜接，板中配少量鋼(gang)筋，上面澆混凝土(tu)層(ceng)，總(zong)厚度(du)約在100-200mm之(zhi)間。
