屋面找坡应满足设计排水坡度要求,结构找坡不应小于3,材料找坡宜为2,檐沟、天沟纵向找坡不应小于1。
The roof slope making shall meet the design drainage slope requirements, the structural slope making shall not be less than 3, the material slope making shall be 2, and the longitudinal slope making of eaves gutter and gutter shall not be less than 1.
找平层应抹平、压光,不得有酥松、起砂、起皮现象。
The leveling layer shall be troweled and calendered without looseness, sanding and peeling.
混凝土表面应密实、平整,不得有蜂窝、麻面、露筋等缺陷。
The concrete surface shall be dense and flat without honeycomb, pitted surface, exposed reinforcement and other defects.
防水层的基层与突出屋面结构的交接处,以及基层的转角处应做成圆弧形,且整齐平顺。
The joint between the base course of the waterproof layer and the protruding roof structure and the corner of the base course shall be made into a circular arc shape, which shall be neat and smooth.
防水施工前,基层应坚实、平整、干净原因分析土建或装修单位与屋面防水公司没有对防水基面进行专项交接验收。
Before waterproof construction, the base course shall be solid, flat and clean. Cause analysis: the civil engineering or decoration unit and the roof waterproof company did not conduct special handover and acceptance of the waterproof base surface.
施工时未按施工要求对基层抹平压光,养护不当。找坡前未认真进行标高测量和设置控制点,结构施工时排水坡向设计不当。
During construction, the base course is not troweled and calendered according to the construction requirements, and the maintenance is improper. Elevation measurement and control points are not carefully set before slope making, and the drainage slope direction is not designed properly during structural construction.
基层灰尘、浮浆等未清理千净,导致防水层与基层粘接不牢、涂膜表观存在针眼孔洞且厚度不均、粘结不牢。
The dust and laitance of the base course are not cleaned, resulting in poor adhesion between the waterproof layer and the base course, needle holes in the surface of the coating film, uneven thickness and poor adhesion.
平立面交接处未抹成圆角或倒角,造成防水卷材折角或防水涂料涂刷不均匀、堆积。
The plane and facade joints are not plastered with rounded corners or chamfers, resulting in uneven corner folding of waterproof coiled materials or uneven and accumulation of waterproof coatings.
基层含水率不满足防水材料施工要求。
The moisture content of the base course does not meet the construction requirements of waterproof materials.
突出屋面的楼梯间、排烟风道、设备基础、女儿墙等构筑物未做现浇混凝土反坎梁。
The staircase, smoke exhaust duct, equipment foundation, parapet and other structures protruding from the roof are not provided with cast-in-situ concrete inverted sill beam.
找坡前未认真进行标高测量和设置控制点,结构施工时排水坡向规划不当预防措施土建或装修单位应该选择屋面防水施工单位,施工前应做好基面交接验收和技术交底,明确基面平整度及排水坡度、坡向等要求。
The elevation measurement and control points are not carefully set before slope making. The drainage slope direction planning is improper during structural construction. The civil engineering or decoration unit should choose the roof waterproof construction unit. Before construction, the foundation surface handover acceptance and technical disclosure should be done to clarify the requirements of foundation surface flatness, drainage slope and slope direction.
找平砂浆应在初凝前完成抹平工序,压光工序应在终凝前完成,终凝后应进行养护。
The leveling mortar shall be troweled before the initial setting, the calendering process shall be completed before the final setting, and the curing shall be carried out after the final setting.
基层表面平整度允许偏差为±3mm(2m靠尺)。
The allowable deviation of base course surface flatness is ± 3mm (2m guiding rule).
防水施工前应将基层灰尘、浮浆等清理干净。
Before waterproof construction, the dust and laitance of the base course shall be cleaned.
基层阴阳角应抹成半径为50mm圆角或尺寸为50x50mm倒角。
The internal and external corners of the base course shall be plastered into a fillet with a radius of 50mm or a chamfer with a size of 50X50mm.
应根据防水材料施工时对基层含水率的要求,处理好基层含水率。
The moisture content of the base course shall be treated according to the requirements for the moisture content of the base course during the construction of waterproof materials.
突出屋面的构筑物墙体部位应设置现浇混凝土反坎梁,高出终完成面不宜小于200mm。
Cast in situ concrete inverted sill beam shall be set at the wall part of the structure protruding from the roof, which shall not be less than 200mm higher than the finished surface.
根据屋面排水平面图确定水落□位置及排水走向,测量和确定高点标高和水落口的标高控制点。
According to the roof drainage plan, determine the water drop position and drainage direction, measure and determine the elevation of the high point and the elevation control point of the water drop.
优先采用结构找坡,不应采用吸水量大的材料找坡。
Structural slope making is preferred, and materials with large water absorption shall not be used for slope making.
屋面结构板小于120mm厚时不宜预埋线管及线盒
When the thickness of roof structural plate is less than 120mm, it is not suitable to embed conduit and junction box
