[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to solve the problem that the basement roof waterproof structure in the prior art is mainly supported by a fine stone concrete protective layer and a thick cement mortar protective layer, the wrapping by the fine stone concrete protective layer and the thick cement mortar protective layer will make the basement roof thicker, affecting the indoor height of the basement, and on the other hand, the double-layer support structure cannot block the transmission of external noise, which will cause the basement to have weak sound insulation and excessive noise, this embodiment provides the following technical solutions:

[0023] A waterproof structure for a building basement roof, comprising a second lower support layer 11, such as Figure 1 and Figure 4 As shown, when laying the basement top plate, first pour the second lower support layer 11 made of concrete. The second lower support layer 11 is used as the supporting basis. After pouring the second lower support layer 11, the subsequent basement top plate can be efficiently made. The upper end of the second lower support layer 11 is provided with the first lower support layer 10. The first lower support layer 10 is formed by alternatingly arranging the first support sheet 15 and the second support sheet 16. The shapes of the first support sheet 15 and the second support sheet 16 are mirror images. The shapes of the first support sheet 15 and the second support sheet 16 are both S-shaped. The first lower support layer 10 formed by alternately sticking the S-shaped first support sheet 15 and the second support sheet 16 in sequence has a cavity reserved inside. The cavity can effectively prevent the transmission of heat and sound.

[0024] In this embodiment, three second reserved cavities 14 are evenly distributed in sequence at the lower end of the first support sheet 15, and first reserved cavities 12 are arranged on both sides of the upper end of the first support sheet 15. Figure 2 As shown, the second reserved cavity 14 is arranged on both sides of the lower end of the second support piece 16, the first reserved cavity 12 is evenly distributed in sequence on the upper end of the second support piece 16, and the first support piece 15 and the second support piece 16 are provided with a support frame 13 on both sides of the first reserved cavity 12. The support frame 13 supports the S-shaped first support piece 15 and the second support piece 16 to improve the overall anti-bending ability of the first lower support layer 10, and the anti-bending ability is improved while reducing the weight of the basement top plate;

[0025] In this embodiment, the first support sheet 15, the second support sheet 16 and the second lower support layer 11 are an integrated structure, and the integrated structure of the first support sheet 15, the second support sheet 16 and the second lower support layer 11 is used as the main support structure of the basement top plate to avoid collapse. On the other hand, a support net 7 is provided at the upper end of the first lower support layer 10. By laying the support net 7 on the surface of the first lower support layer 10, it can be avoided that the upper concave position of the first lower support layer 10 cannot be normally laid with the remaining structure, and the support of the support net 7 can retain the concave position of the first lower support layer 10 facing the upper end;

[0026] In this embodiment, the first lower support layer 10 has a desiccant applied to the concave position facing the support net 7, such as Figure 2 As shown, the first lower supporting layer 10 is used for support, sound insulation and heat insulation, while ensuring that the first lower supporting layer 10 is dry to prevent moisture from continuously spreading into the basement;

[0027] In this embodiment, if Figure 1 and Figure 2 As shown, the support net 7 is formed by cross-welding of a first transverse support bar 8 and a second transverse support bar 9, and the first transverse support bar 8 and the second transverse support bar 9 are both welded to the upper end of the first lower support layer 10;

[0028] In this embodiment, a crushed stone filter layer 3 is disposed on the upper end of the support net 7, and a geotextile filter layer 2 is disposed on the upper end of the crushed stone filter layer 3. Figure 1 , Figure 2 and Figure 3 As shown, the geotextile filter layer 2 and the crushed stone filter layer 3 filter the liquid in contact with the upper end, filter foreign matter to the outside, and prevent foreign matter from flowing into the top plate along with the liquid. The liquid without foreign matter will evaporate and disappear as time goes by if it stays in the geotextile filter layer 2 and the crushed stone filter layer 3 for a long time. On the other hand, the geotextile filter layer 2 and the crushed stone filter layer 3 can limit the liquid from continuously moving toward the first lower support layer 10 by filtering.

[0029] In this embodiment, a green belt 1 is provided on the upper end of the geotextile filter layer 2, and the soil in the green belt 1 can preferentially absorb the liquid. Figure 1 and Figure 2 As shown, liquid is prevented from flowing into the first reserved cavity 12 at the lower end, and the waterproof capability of the basement top plate and the aesthetics can be improved by the green belt 1;

[0030] In this embodiment, if Figure 1 and Figure 2 As shown, an isolation layer 4 is provided at the lower end of the second lower support layer 11. The isolation layer 4 is a glass fiber cloth. The isolation layer 4 can support and wrap the upper gravel filter layer 3 and the geotextile filter layer 2 to prevent particles from dripping to the lower end of the waterproof structure and prevent the waterproof structure from being dented and causing changes in its appearance.

[0031] In this embodiment, if Figure 1 and Figure 2 As shown, a waterproof roll 5 is provided at the lower end of the isolation layer 4. The waterproof roll 5 is an asphalt waterproof roll. The laying of the waterproof roll 5 can block the liquid left at the upper end and prevent the liquid inside the basement from flowing into the basement roof.

[0032] In this embodiment, if Figure 1 and Figure 2 As shown, a heat-insulating layer 6 for heat insulation is provided between the isolation layer 4 and the waterproof membrane 5. The heat-insulating layer 6 can prevent the temperature at the upper end from being transferred to the basement through the waterproof structure.

[0033] Working principle: When the basement top slab waterproof structure is used for waterproofing and as a support for the basement top slab, the external liquid will first contact the uppermost green belt 1, and the liquid will be absorbed by the soil inside the green belt 1. The liquid that is not absorbed will pass through the geotextile filter layer 2 and the gravel filter layer 3 in turn. The geotextile filter layer 2 and the gravel filter layer 3 will filter the liquid while restricting the flow of the liquid, so that most of the liquid will be retained in the geotextile filter layer 2 and the gravel filter layer 3, and the isolation layer 4 will wrap and restrict the liquid that passes through the geotextile filter layer 2 and the gravel filter layer 3 in turn at the upper end, maintain the shape of the upper structure, and at the same time wrap the flowing liquid to prevent the liquid from continuing to flow. The support of the basement top slab is mainly supported by the second lower support layer 11, and the first lower support layer 10 formed by the first support sheet 15 and the second support sheet 16 is auxiliary supported. The desiccant applied on the surface of the first support sheet 15 and the second support sheet 16 can further ensure that the top slab structure can be further kept dry to prevent liquid from seeping through the top slab from the upper end.
