In addition, the outside of outermost layer elastic body water-proof layer 6 is further coated with anti-ultraviolet coating or sealant layer together.

As shown in figure 13, the construction method of above-mentioned waterproof construction, it is further comprising the steps of including above-mentioned waterproof construction,

1) base treatment agent is applied in 2 both sides of seam；

2) after base treatment agent curing, positioning foam rods 3 are filled in into seam 2 with positioning device；

3) after positioning foam rods 3 fix, pasta elastic body water-proof layer 6 is squeezed into seam 2 with positioning Jiao Zui；

4) before elastic body water-proof layer 6 is without surface drying, spacer rod 7 is pressed into seam 2 with positioning device；

5) repeat the above steps 3-4, until outermost elastic body water-proof layer 6 and the outside flush of seam 2.

It is as follows：

High compactness high adhesiveness base treatment agent, curing are coated on 2 both sides porous material 5 of seam.Fill in positioning bubble Foam stick 3 using positioning device, withstands positioning plate 12 (disk, bar) by the edge in 2 outside of seam, positioning foam rods 3 is expressed to The depth specified；Using Jiao Zui, machinable glue mouthpiece 18 is connected on 16 packing tube of glue mouth body, the scraper plate 19 of Jiao Zui is cut Suitable width and height are cut, elastic body water-proof layer 6 is squeezed into 2 bosom of seam, is pushed ahead in seam 2, is beaten real；It scrapes The painting of elastic body water-proof layer 6 is scraped corresponding design thickness by plate 19 as injecting glue promotes.It is most thin not less than 1.0mm, it is most thick must not Higher than 9mm, preferred 3-7mm thickness is preferred.Before elastic body water-proof layer 6 is without surface drying, spacer rod 7 is filled in, is filled using positioning It puts, spacer rod 7 is pressed into seam 2 so that it comes into full contact with elastic body water-proof layer 6, and extra paste glue or sticky Coating is squeezed out by 7 reserved passageway of spacer rod close to 1 part of seam inner wall.Elasticity is injected again according to the above method Body waterproof layer 6, still, glue mouth depth are adjusted to design requirement by glue mouth positioning plate 17 (disk, bar) positioning requirements, then adjust every Depth localization device from stick 7, fills in spacer rod 7 again according to the method described above；It is repeated with this, multiple tracks spacer rod 7 and elastomer 6 alternately operating of waterproof layer；To last one of elastic body water-proof layer 6, with scraper plate 19 by extra elastic body water-proof layer 6 along seam 2 outer walls are wiped off, are struck off or concave-shaped arc surface, are removed at first in the U.S. line paper on 2 outside both sides of seam or other self-adhesion Protection glue bands, most Afterwards in the outermost of elastic body water-proof layer 6 coating together anti-ultraviolet coating or sealant layer.
