Heat insulation structure for concrete building

The heat insulation structure for the concrete building comprises a first heat insulation plate and a second heat insulation plate which are connected to the inner wall of a first heat insulation shell and the inner wall of a second heat insulation shell in an inserted mode, a partition plate is fixedly connected to the interior of the first heat insulation plate, and one side of the partition plate is filled with a polyurethane foam layer. The other side of the partition plate is filled with a waterproof heat insulation powder layer. Through cooperative arrangement of a polyurethane foam layer and a waterproof heat insulation powder layer, the heat insulation effect of the first heat insulation plate can be better through the high stability performance of the polyurethane foam layer and the moisture-proof performance of the waterproof heat insulation powder layer, and meanwhile the waterproof and moisture-proof performance of a building can be enhanced; through the cooperative arrangement of the aerogel felt
