天津/北京车间环氧防腐地坪漆施工技术要求多,中科京工地坪公司这里只简单介绍对混凝土基层要求:
1、基层地面在浇注混凝土前必须铺设防水层,工程施工不能因为超出报价(格)就省去不做,这样不可以!
2、天津/北京中科京工环氧防腐地坪漆施工公司要求混凝土强度等级须达到C30或以上。
3、基层须用抹平机抹光,平整度不超过±2mm/2m。
4、浇注混凝土并同时一次性找平,以避免空鼓,脱层,起砂等质量问题。
5、混凝土必须养护28天以上,在深度为20mm的厚度层时,含水率不应大于6%;
6、混凝土地面不允许有任何脂肪,油迹,油漆及水泥残渣等物。
7、 基层坡度必须进行检测并应符合设计要求,其允许偏差应为坡度长的±0.2%,最大偏差不得大于30mm。
8、所有裂缝和坑洼必须以中科京工环氧树脂砂浆材料修补,才能进行之后的施工安排!
9、 天津/北京中科京工环氧防腐地坪漆施工公司要求承重及结构件等重要混凝土浇筑宜采用大型清水模板一次制成。当采用钢模板时,选用的脱模剂不应污染基层。
10、地面抗拉强度大于1.5。
1, the ground should be laid waterproof layer in the pouring of concrete,construction can not because it is beyond price won't do, so can not!
2, the general strength of concrete is required to achieve C30 or above.
3, the basic use smoothing machine finishing, flatness is less than 2mm/2m.
4, concrete pouring and one leveling, in order to avoid hollowing,delamination, sand and other quality problems.
5, concrete need maintenance 28 days above, in the depth of layer thickness is 20mm, the moisture content should not be greater than 6%;
6, concrete surface is not allowed to have any fat, grease, paint and cement residue.
7, the slope must be detected and should comply with the design requirements, the deviation should be allowed to slope length + 0.2%, the maximum deviation of not more than 30mm.
8, all the cracks and potholes in Beijing, must be based on epoxy resin mortar materials to repair, to the construction of the arrangement!
9, bearing and other pieces of the structure concrete pouring should be adopted in large water main template made at one time. When using thesteel formwork, mould release agent selection should not be the pollution level.
10, the tensile strength is more than 1.5.
以上是针对天津/北京车间环氧防腐地坪漆工程混凝土基层施工要求,价格虽然略高,但是中科京工地坪公司认为非常重要!
