[0028] The waterproof filling piece 5 can be selected from two-component hard foam polyurethane or single-component polyurethane foam. The heat preservation plate 6 can be selected from graphite polystyrene board, rock wool board, extruded board or polyurethane board.

[0029] The bottom waterproof layer is arranged between the concrete floor and the heat preservation layer, so that the heat preservation layer is prevented from being filled with water due to the moisture return of the concrete floor 1. The top waterproof layer is arranged above the heat preservation layer, so that the water flow above the roof is prevented from flowing into the heat preservation layer. The heat preservation layer is arranged in the form of single-layer heat preservation plates 6, and the gaps between the adjacent heat preservation plates 6 are completely filled by the waterproof filling pieces 5, so that the waterproof performance of the heat preservation layer is ensured.

[0030] In one embodiment, the gaps between the heat preservation layer and the bottom waterproof layer are also completely filled by the waterproof filling pieces 5. The gaps between the heat preservation layer and the bottom waterproof layer are completely filled by the waterproof filling pieces 5, so that the water is prevented from entering the gaps between the heat preservation layer and the bottom waterproof layer, and the heat preservation layer is prevented from being lifted by the water below and being damaged.

[0031] Further, in order to further improve the overall strength of the heat preservation waterproof structure, the waterproof filler 5 between the heat preservation plates 6 is formed in an integral structure with the waterproof filler 5 between the heat preservation layer and the bottom waterproof layer. By connecting the waterproof fillers 5 to each other in contact to form an integral whole, the gaps in the heat preservation layer are completely filled, thereby improving the overall strength of the waterproof filler 5 and avoiding water from flowing into the space between the waterproof filler 5 and the heat preservation layer due to excessive water pressure.

[0032] In one embodiment, in order to enhance the effect of the waterproof filler 5 on isolating water vapor after filling the gaps between the heat preservation layers, a filling groove 9 is provided on the opposite side of the adjacent heat preservation plates 6, and the waterproof filler 5 completely fills the filling groove 9. By providing the filling groove 9, the distance of the water channel when water seeps in can be increased, thereby enhancing the waterproof effect of the waterproof filler 5 in the heat preservation layer. Moreover, the filling groove 9 can also increase the filling space of the waterproof filler 5, avoiding the formation of new gaps between the waterproof fillers 5 and between the waterproof fillers 5 and the heat preservation plates 6.

[0033] In one embodiment, the bottom waterproof layer includes a vapor barrier roll 4 and a non-cured rubber asphalt as a waterproof coating 3 arranged in layers.

During construction, first, the sloping layer 2 is formed on the roofing base according to the design requirements by using fine stones and concrete, which can prevent roof water and drain roof water in time. After the sloping layer 2 hardens to the design requirements, the surface of the sloping layer 2 is cleaned, and then 5mm anti-cracking waterproof mortar is used for leveling treatment, thereby providing a high flatness and non-powder surface matrix for the subsequent waterproof layer construction. Then, the non-cured rubber asphalt is constructed by using heating equipment combined with the ambient temperature, and then the vapor barrier 4 is laid, which is fixed and bonded on the sloping layer 2 by the non-cured rubber asphalt. The vapor barrier 4 is fixed and bonded by the non-cured rubber asphalt, which fills the cavity between the vapor barrier 4 and the matrix and ensures full adhesion. The vapor barrier 4 can prevent indoor moisture from entering the insulation layer and avoid the influence of water vapor on the insulation and durability of the insulation layer. Then, 10mm-thick two-component hard foam polyurethane is sprayed as the bottom waterproof filler 5 according to the material process requirements, and then the insulation board 6 is bonded in sequence, which is fixed and bonded above the vapor barrier 4 by the bottom waterproof filler. After the insulation board 6 is laid, high-density two-component hard foam polyurethane is continuously sprayed and filled in the gap between the insulation boards 6. The two-component hard foam polyurethane can fully fill the joint of the insulation board 6 and the cavity between the insulation board 6 and the vapor barrier 4, and the filling density of the two-component hard foam polyurethane is ensured to be 50kg / m 3 The closed cell rate is ensured to be more than 94%, which can play a good waterproof role. Finally, the self-adhesive modified asphalt waterproof roll and the surface layer modified slate asphalt waterproof roll 8 are constructed, and the slate asphalt waterproof roll 8 is bonded and fixed on the top of the insulation layer by the self-adhesive asphalt waterproof roll 7. By introducing high-density hard foam polyurethane to fill the joint of the insulation board 6 and the bottom layer of the insulation board 6 in the roofing insulation waterproof structure, the vapor barrier 4 is fully adhered to the matrix by the non-cured rubber asphalt, thereby realizing that the entire insulation waterproof system is free of cavity and water leakage gap. At the same time, in order to prevent the poor combination of hard foam polyurethane and the insulation board 6, the shrinkage of the insulation board 6 and other factors from causing vertical through gaps between the polyurethane and the insulation board 6, the filling groove 9 in the form of double concave grooves is designed between the insulation boards 6, which increases the water leakage channel distance, increases the hard foam polyurethane filling space, and avoids the formation of new gaps in the gap between the insulation boards 6 after the deformation of the insulation boards 6.
