二、 作業(yè)條件
1、 基層應(yīng)進行檢查，并辦理交接驗收手續(xù)。基層表面應(yīng)平整光滑，不得有起砂、裂縫、松動等現(xiàn)象，突出部位應(yīng)平滑過渡。
2、 基層與屋面突出部位（如女兒墻、墻體、管道等）相連接處，應(yīng)做成半徑為100～150㎜的圓弧形。
3、 施工溫度在5℃以上。下雨或雨后尚未干燥或有四級以上大風天氣，不得施工�；鶎討�(yīng)基本干燥，含水率不大于15%。
4、 備齊機具設(shè)備，搭設(shè)好材料垂直運輸井架，安裝好卷揚提升系統(tǒng)設(shè)備。
三、 施工操作工藝
1、 工藝流程
清理基層→刷第一遍膠料→表干后，刷第二遍涂料，同時鋪第一層玻璃布→實干后，刷第三遍膠料→表干后，刷第四遍膠料，同時鋪第二層玻璃布→實干后，刷第五遍膠料→表干后，刷第六遍膠料→閉水試驗。
2、 清理基層
將基層表面的突出物、砂漿疙瘩等異物清除干凈，不得有
End of roofing and technology exchange
Project Name: Luoyang Opera House (People's Hall)
Content:
1, material requirements
1, SBS asphalt waterproof rubber elasticity
Water-soluble, odorless, viscous black liquid, solid content of greater than 50% of its main technical performance indicators should be consistent with the provisions of product standards, and should the factory certification.
2, the main tool
Cheung Ping-large brush, small brush with short Bing, scythes scraper, a small scraper, a small trowel, small drum, the size of broom, scissors, rolling brush and so on.
Second, the operating conditions
1, grass-roots should be checked, and go through the transfer of inspection procedures. Primary surface should be smooth, do not have sand, cracks, loosening phenomenon, highlighting parts of the transition should be smooth.
2, primary and roof protruding parts (such as the parapet, wall, piping, etc.) are connected, he shall be made for the 100 to 150 mm radius of the arc-shaped.
3, the construction temperature above 5 ℃. Rain or rain with four more yet to dry or windy weather, not construction. Grass-roots level should be the basic drying, water content not more than 15%.
4, get ready machinery equipment, vertical transportation derrick erection of good material, installed hoist system equipment.
Third, the construction operation process
1, process
Clean-up grassroots → → rubber brush the first pass is dry, paint brush a second time, while laying the first layer of glass cloth → hard work, the brush rubber → third time is dry, brush over the fourth rubber, laying the same time The second layer of glass cloth → hard work, the brush all over the compound → Fifth is dry, brush the sixth time → closed water test compound.
2, cleaning up the grassroots
The primary surface protrusions, mortar and other foreign body cleanse pimple may not have
