In the figure, 1-base course wall; 2-waterproof layer; 3-supporting the keel; 4-an insulating layer; 5-a finishing layer; 6-an anchor member; 7-a resilient gasket; 8-connecting rod structure; 9-waterproof expansion sleeve.
Detailed Description
The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.
As shown in fig. 1, the polyurethane system for thermal insulation spraying inside the building exterior wall of the present invention sequentially comprises a base wall 1, a waterproof layer 2, a plurality of groups of supporting keels 3, a thermal insulation layer 4 and a finishing layer 5 from inside to outside, wherein:
the waterproof layer 2 is directly arranged on the inner wall surface of the base layer wall body 1 and is used for blocking external water vapor from permeating into the heat preservation layer 4 and preventing the heat preservation effect from being influenced; the supporting keel 3 is perpendicular to the base layer wall 1, and one end of the supporting keel is fixed on the wall base layer 1 through an anchoring part 6 and used for supporting the heat insulation layer 4 and the decorative surface layer 5; the heat-insulating layer 4 is a sprayed polyurethane layer, so that the heat-insulating continuity is ensured, and the heat-insulating effect is improved; the decorative surface layer 5 is fixedly arranged at the other end of the support keel 3.
Since the anchor member 6 penetrates the waterproof layer 2, the waterproof performance of the penetrated portion is greatly lowered. As shown in fig. 2, a water-absorbing expansion sleeve 9 is sleeved outside the anchoring member 6, when rainwater or water vapor in the environment permeates into the base layer wall 1, the water-absorbing expansion sleeve 9 absorbs part of water and then expands, so that the anchoring member 6 and the water-absorbing expansion sleeve 9 are in interference fit, and the base layer wall 1, the waterproof layer 2 and the heat-insulating layer 4 at the penetrating position are in interference fit with the anchoring member 6, so that the water vapor is prevented from continuously permeating into the heat-insulating layer 4; furthermore, an elastic gasket 7 is sleeved outside a water absorption expansion sleeve 9 of the anchoring piece 6, and the elastic gasket 7 abuts against the waterproof layer 2, so that the waterproof performance of the anchoring piece 6 at the penetrating point of the waterproof layer 2 is further enhanced.
