[0002] The waterproof structure of the outer thermal insulation outer wall grid gap is a very important part in building, which can effectively prevent water penetration and protect the performance of the wall and thermal insulation material. Currently, the grid gap between the building thermal insulation outer wall is usually sealed directly by sealant. Due to the slight vibration phenomenon of the building wall, the building thermal insulation outer wall in the grid gap area is affected by vibration and is prone to corresponding displacement between them, which causes the sealant in the grid gap to be squeezed off and unable to prevent water. At the same time, the structure and strength of the waterproof structure in the grid gap of the building thermal insulation outer wall are not reasonable, which causes rainwater or water vapor to accumulate in the grid gap and leads to leakage over a long period of time. On the other hand, the strength is not enough, which causes the waterproof structure to crack and deform, especially in the case of temperature change and material expansion and contraction, which seriously affects the waterproof effect of the building thermal insulation outer wall grid gap.
