    機械固定(ding)(ding)即采用(yong)專用(yong)固定(ding)(ding)件(jian)，如金(jin)屬墊(dian)片、螺釘、金(jin)屬壓條等，將聚氯(lv)乙(yi)烯（PVC）或(huo)熱塑性(xing)聚烯烴(jing)（TPO）防(fang)水卷材以及其他屋面層(ceng)次的(de)材料(liao)機械固定(ding)(ding)在屋面基層(ceng)或(huo)結構層(ceng)上。機械固定(ding)(ding)包(bao)括(kuo)點式固定(ding)(ding)方(fang)式和(he)線性(xing)固定(ding)(ding)方(fang)式。固定(ding)(ding)件(jian)的(de)布置與承載能力應根據實驗結果和(he)相關規(gui)定(ding)(ding)嚴格設(she)計(ji)。

    聚氯乙烯（PVC）或熱塑(su)性聚烯烴（TPO）防(fang)水(shui)卷(juan)材(cai)的搭接(jie)是由(you)熱風焊(han)接(jie)形成連(lian)續整體的防(fang)水(shui)層。焊(han)接(jie)縫是因(yin)分(fen)子鏈互相滲透、纏繞形成新的內聚焊(han)接(jie)鏈，強度高于卷(juan)材(cai)且(qie)與卷(juan)材(cai)同壽命。

    屋面為壓型(xing)鋼板(ban)(ban)的基(ji)(ji)板(ban)(ban)厚度(du)不(bu)宜小(xiao)于(yu)0.75mm，且基(ji)(ji)板(ban)(ban)最小(xiao)厚度(du)不(bu)應小(xiao)于(yu)0.63mm，當基(ji)(ji)板(ban)(ban)厚度(du)在0.63~0.75mm時應通過(guo)(guo)固定釘拉拔試(shi)驗；鋼筋混凝土板(ban)(ban)的厚度(du)不(bu)應小(xiao)于(yu)40mm，強度(du)等級(ji)不(bu)應小(xiao)于(yu)C20，并應通過(guo)(guo)固定釘拉拔試(shi)驗。
