1、屋面工程卷材鋪貼方向,應(yīng)根據(jù)屋面坡度方向而定,在坡度名≤3%時,卷材平行于屋脊方向鋪設(shè),且卷材搭接縫順流水方向。屋面先遠后近,統(tǒng)一平面內(nèi)先鋪雨水口、伸縮縫、女兒墻轉(zhuǎn)角等細部,然后從屋面較低處開始鋪貼。
1, roofing tiles, roof slope should be based on the direction and, in a slope less than 3% when the coil laying parallel to the ridge direction and the direction of the water flow along the coil lap seam. The roof first distant past, the same plane Xianpu rain, joints, corner parapet and detail, and then from the lower roof start paving.
2、卷材鋪貼前應(yīng)按照卷材的寬度,留出搭接縫尺寸(卷材搭接寬度應(yīng)吻合相干規(guī)范要求,高分子卷材膠粘80mm(北京設(shè)計),單縫焊60mm,改性瀝青卷材膠粘100mm,熱熔及自粘 80mm ),將鋪貼卷材的基準線彈好,以便按此基準線進行卷材鋪貼施工。
2, before the tiles should be in accordance with the coil width, leaving joint size (coil lap width should comply with the relevant specifications, high polymer sheet adhesive 80mm, single seam 60mm, modified asphalt adhesive and hot melt adhesive 100mm, 80mm), the baseline paving material will play, in order to coil paving construction according to the datum line.
3、施工時(河北人事考試),相鄰兩幅卷材短邊搭接縫應(yīng)錯開,且不得小于500mm(九寨溝旅游租車),上下兩層卷材長邊搭接縫應(yīng)錯開,且不得小于幅寬的1/3。
3, the construction, the short side two consecutive coil lap joints should be staggered, and not less than 500mm on the two layer coil long side lap joints should be staggered, and shall not be less than the width of 1/3.
4、熱熔卷材應(yīng)用噴燈充分烤融搭接邊上基層卷材外觀瀝青涂蓋層,邊熱熔邊滾壓粘實,且有熔融瀝青從邊端擠出,形成勻質(zhì)瀝青條。
4, hot coil application fully melt on the edge of the lap a lower surface of membrane asphalt coating, hot melt edge edge rolling stick, and molten asphalt extruded from the edge, forming a homogeneous asphalt.
5、搭接縫采膠粘、自粘時,黏結(jié)后,采用壓輥在上層卷材搭接縫處的頂面均勻滾壓, 使接縫密實黏合。宜在搭接縫100mm寬加涂合成高分子密封膠作增強密封處理。
5, joint production, self-adhesive adhesive, adhesive, the pressure roller in the upper coil lap seam at the top of the uniform rolling, the adhesive joints dense. Suitable for lap joint 100mm wide coated synthetic polymer sealant for strengthening sealing treatment.
