1、下层要求:用切隔机将伸缩缝两边各50cm处切开(防止打錾时损坏相邻的大理石),然后将切隔处和伸缩缝之间的大理石及砂浆层打掉,直到下层(混凝土楼板面)清理干净。
1, basic requirements: cut machine will be open on both sides of the expansion joint at 50cm (adjacent to prevent damage of the marble, hit the chisel) and then cut and the joints between the marble and the mortar layer, until the base (concrete floor) clean.


2、将伸缩缝两边10cm宽打“V”形模垂深5cm。
2, the expansion joint on both sides of the width of the 10cm "V" shape deep 5cm.


3、用水泥砂浆将打成的“V”形两侧找平层。
3, with cement mortar will be labeled "V" shape on both sides of the leveling layer.


4、在伸缩缝底部用50×50cm遇水膨胀止水条嵌底。
4, at the bottom of the expansion joint with 50 * 50cm water expansion sealing strip.


5、用双组份聚氨酯密封膏将止水条与结构层密封、压实。
5, the use of two-component polyurethane sealant to seal the water seal and structural layer, compaction.


6、铺设三元乙丙橡胶屋顶防水卷材。
6, the laying of three ethylene propylene rubber waterproofing membrane.


(1)下层清理。将下层外观突出物等铲平,并将尘土杂物彻底清扫干净。

(4)铺设卷材。涂胶20分钟左右,基本不粘手后,用手一边压一边驱除空气,粘合后应再用压辊滚压一遍(广州礼品公司),粘结牢固不翅边,不起鼓,然后用聚氨酯密封膏封口。
(4) laying of coiled material. Glue 20 minutes or so, the basic non stick hand, while pressing the side of the hand to remove the air, the adhesive should be used after the pressure roller rolling again, firmly bonded to the edge of the wing, can not afford to drum, and then sealed with polyurethane sealant.


7、试水24小时后,做屋顶防水保护层。
7, test the water for 24 hours, do waterproof protective layer.


8、铺设大理石用1:2的水泥砂浆摊平约20毫米(网页设计价格),接着将大理石呈水平状盖上,要轻拿轻放,不要让利器划伤外观,并用手轻压或用橡皮锤轻轻敲击大理石(成都人事考试网首页),务必使之平整,并与地面粘结坚固,不出现闲暇,否则经人踩踏容易断裂。铺设时要随时用棉丝之类的软性布将缝中挤出的浆液擦干净。铺设完后,可在板面定期找蜡,确保其晶亮的光泽。
8, the laying of 1:2 cement mortar with marble paved ca. 20 mm, then the marble horizontal cover, tohandlegentlyand, don't let the scratched surface, and gently press or with a rubber hammer gently tap to make sure the smooth marble, and the ground is not strong bond, void, or by trampled to fracture. Laying at any time with a soft cloth, such as cotton yarn will be squeezed out of the slurry in the seam clean. After the laying of the board can be on a regular basis to find the wax, to ensure its shiny crystal luster.
