彩鋼屋面板采光板連接節點

采(cai)(cai)光(guang)板(ban)(ban)(ban)(ban)(ban)(ban)根據材料的(de)不同可分為玻璃纖維(wei)增強聚醋采(cai)(cai)光(guang)板(ban)(ban)(ban)(ban)(ban)(ban)、聚碳酸(suan)醋采(cai)(cai)光(guang)板(ban)(ban)(ban)(ban)(ban)(ban)等類(lei)型。由(you)于采(cai)(cai)光(guang)板(ban)(ban)(ban)(ban)(ban)(ban)與(yu)(yu)彩鋼(gang)屋面(mian)壓(ya)型板(ban)(ban)(ban)(ban)(ban)(ban)的(de)熱膨脹(zhang)系數不一(yi)致(zhi)，再加上兩(liang)(liang)種(zhong)(zhong)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)波形不太吻合(he)，很容易使采(cai)(cai)光(guang)板(ban)(ban)(ban)(ban)(ban)(ban)與(yu)(yu)屋面(mian)的(de)交接(jie)(jie)不嚴密、接(jie)(jie)日處(chu)理密封(feng)(feng)(feng)性差，導致(zhi)設有采(cai)(cai)光(guang)帶(dai)的(de)屋面(mian)中出(chu)現(xian)滲漏、滴水現(xian)象(xiang)。在設計中，應選(xuan)擇采(cai)(cai)光(guang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)厚度(du)、剛度(du)與(yu)(yu)彩鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)厚度(du)、剛度(du)協調，使兩(liang)(liang)種(zhong)(zhong)板(ban)(ban)(ban)(ban)(ban)(ban)波形一(yi)致(zhi)，注意兩(liang)(liang)種(zhong)(zhong)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)搭(da)接(jie)(jie)長度(du)與(yu)(yu)接(jie)(jie)縫的(de)密封(feng)(feng)(feng)。在滿足采(cai)(cai)光(guang)、檁條(tiao)要(yao)求條(tiao)件下(xia)(xia)，盡可能(neng)減小(xiao)采(cai)(cai)光(guang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)厚度(du)，避免出(chu)現(xian)由(you)于采(cai)(cai)光(guang)板(ban)(ban)(ban)(ban)(ban)(ban)多(duo)層(ceng)搭(da)接(jie)(jie)而造(zao)成的(de)搭(da)接(jie)(jie)日空隙過大。采(cai)(cai)光(guang)板(ban)(ban)(ban)(ban)(ban)(ban)與(yu)(yu)彩鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)水平搭(da)接(jie)(jie)處(chu)，泛水板(ban)(ban)(ban)(ban)(ban)(ban)下(xia)(xia)日與(yu)(yu)彩鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)搭(da)接(jie)(jie)不低(di)于250mm，且設置擋(dang)水板(ban)(ban)(ban)(ban)(ban)(ban)，并發(fa)泡堵(du)頭。采(cai)(cai)光(guang)帶(dai)與(yu)(yu)彩鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)縱(zong)向(xiang)搭(da)接(jie)(jie)處(chu)，泛水板(ban)(ban)(ban)(ban)(ban)(ban)下(xia)(xia)日與(yu)(yu)彩鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)應搭(da)接(jie)(jie)2個波峰(feng)，且其(qi)端部應下(xia)(xia)彎(wan)至波谷。泛水板(ban)(ban)(ban)(ban)(ban)(ban)上日均應伸人采(cai)(cai)光(guang)帶(dai)內且不低(di)于60mm，其(qi)端部應上彎(wan)5mm左右(you)，并滿封(feng)(feng)(feng)丁基密封(feng)(feng)(feng)膠。
