Thermal insulation outer wall structure and construction method thereof

The invention discloses a heat preservation outer wall structure and a construction method thereof.The heat preservation outer wall comprises a wall body, a heat preservation plate and anchor bolts, bonding mortar is arranged between the wall body and the heat preservation plate, a layer of first rendering coat mortar is arranged on the outer side of the heat preservation plate, and first gridding cloth is arranged in the first rendering coat mortar; the anchor bolt sequentially penetrates through the first rendering coat mortar and the bonding mortar to be inserted into the wall body so as to anchor the insulation board on the outer side of the wall body; a layer of second rendering coat mortar is arranged on the outer side of the first rendering coat mortar, and second gridding cloth is arranged in the second rendering coat mortar. The insulation board of the insulation outer wall obtained through the construction method is good in anchoring strength, and the insulation board can be effectively prevented fr
