[0039] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] like Figure 1 and Figure 2 The present application provides a waterproof structure, wherein the waterproof structure includes a substrate 1 , a waterproof roll 2 , a sealing layer 3 and a backfill layer 4 .

[0041] The substrate 1 can be a plate installed parallel to a horizontal plane, such as a basement floor. The substrate 1 has a first side 11 and a second side 12 disposed opposite each other along a first direction X. When the substrate 1 is installed parallel to the horizontal plane, the first direction X is vertical, the first side 11 is the top of the substrate 1, and the second side 12 is the bottom of the substrate 1.

[0042] A sealing groove 13 is formed on the first side 11 of the substrate 1. The sealing groove 13 has a first groove wall 131 and a second groove wall 132 oppositely disposed along a second direction Y. The first direction X is perpendicular to the second direction Y. When the first direction X is a vertical direction, the second direction Y is a horizontal direction.

[0043] The waterproof roll 2 includes a first part 21, a second part 22 and a third part 23 connected in sequence. The waterproof roll 2 is a whole. The first part 21, the second part 22 and the third part 23 are formed by bending the waterproof roll 2 during laying to ensure the overall waterproof performance of the waterproof roll 2.

[0044] The first portion 21 is laid on the bottom of the sealing groove 13. Specifically, the first portion 21 covers the entire area of ​​the bottom of the sealing groove 13, that is, along the first direction X, the projection of the first portion 21 coincides with the projection of the bottom of the sealing groove 13. The first portion 21 covers the entire bottom of the sealing groove 13, thereby maximizing the connection area between the waterproof membrane 2 and the bottom of the sealing groove 13; the second portion 22 is laid on the first groove wall 131, which can further increase the connection area between the waterproof membrane 2 and the inner surface of the sealing groove 13 while achieving the connection between the first portion 21 and the bottom of the sealing groove 13; the third portion 23 is laid on at least a portion of the surface of the first side 11 of the substrate 1 to achieve waterproofing of a local position of the first side 11 of the substrate 1.

[0045] The sealing layer 3 is filled in the sealing groove 13, and the sealing layer 3 covers the first part 21 along the first direction X. The sealing layer 3 is sealed with the second part 22 and the second groove wall 132 respectively; the first part 21 is reliably pressed and fixed to the groove bottom of the sealing groove 13, and the gap between the first part 21 and the second groove wall 132 of the sealing groove 13 is completely sealed, so that the end of the waterproof membrane 2 is reliably sealed.

[0046] The backfill layer 4 is filled in the sealing groove 13, and the backfill layer 4 covers the sealing layer 3 along the first direction X. The backfill layer 4 is sealed with the second part 22 and the second groove wall 132 respectively. The backfill layer 4 can further compact the sealing layer 3 and the first part 21 to further improve the bonding strength between the waterproof membrane 2 and the sealing groove 13. At the same time, the backfill layer 4 serves as an isolation layer and a base layer on the upper part of the sealing layer 3, thereby improving the waterproof effect at the sealing groove 13. The backfill layer 4 can provide protection for the sealing layer 3 and extend the service life of the sealing layer 3.

[0047] The waterproof structure provided in the present application is provided with a sealing groove 13 on the substrate 1, and the second part 22 of the waterproof membrane 2 is laid on the first groove wall 131 of the sealing groove 13, and the first part 21 is laid on the groove bottom of the sealing groove 13. By sequentially filling the sealing groove 13 and the backfill layer 4 in the sealing groove 13, and making the sealing groove 13 and the backfill layer 4 simultaneously connected to the second part 22 of the waterproof membrane 2 and the second groove wall 132 of the sealing groove 13, the first part 21 and the second part 22 can be effectively fixed and sealed in the sealing groove 13, which is equivalent to fixing the end of the waterproof membrane 2 in the sealing groove 13, and increasing the connection area between the waterproof membrane 2 and the substrate 1, thereby improving the sealing performance between the waterproof membrane 2 and the substrate 1, and ensuring the waterproof performance of the substrate 1.

[0048] like Figure 1 and Figure 2 As shown, the waterproof structure provided by the present application, wherein the first part 21 is fixedly connected to the bottom of the sealing groove 13 by the positioning component 5, so as to pre-position the first part 21 before filling the sealing layer 3, thereby reducing unnecessary displacement of the first part 21 due to external force, and the sealing layer 3 seals and covers the positioning component 5 along the first direction X, and can seal the connection between the positioning component 5 and the first part 21.

[0049] like Figure 1 and Figure 2 As shown, the waterproof structure provided by the present application, wherein the positioning component 5 includes a pressure strip 51 and a positioning member 52.

[0050] The pressure strip 51 is provided on the side of the first portion 21 facing away from the bottom of the sealing groove 13 and is pressed against the surface of the first portion 21 along the first direction X. A positioning member 52 extends through the pressure strip 51 and the first portion 21 along the first direction X, with a portion of the positioning member 52 extending through the bottom of the sealing groove 13 and connected to the base plate 1. Optionally, the positioning member 52 may be a bolt. The positioning member 52 positions the first portion 21, and the pressure strip 51 increases the area between the pressure strip and the first portion 21, thereby evenly applying pressure to the first portion 21 and reducing the risk of damage to the first portion 21 due to concentrated force.

[0051] Optionally, the waterproof structure provided in the present application is characterized in that the distance between the pressure strip 51 and the edge of the first part 21 away from the second part 22 is 10 mm to 20 mm, so as to ensure that the positioning member 52 has a certain distance from the edge of the first part 21, which is conducive to the dispersion of the force when subjected to external force, and reduces the possibility of the first part 21 breaking at the position penetrated by the positioning member 52.

[0052] like Figure 2 As shown, the waterproof structure provided by the present application, wherein, along the first direction X, the sum of the thickness of the sealing layer 3 and the thickness of the first part 21 is greater than or equal to half the depth of the sealing groove 13, so that the sealing layer 3 has a certain filling thickness to ensure the connection area between it and the second groove wall 132 and the second part 22, thereby ensuring the sealing effect.

[0053] like Figure 2 As shown, the waterproof structure provided by the present application, wherein, along the first direction X, the surface of the backfill layer 4 facing away from the sealing layer 3 is flush with the surface of the first side 11 of the substrate 1 to fill the sealing groove 13, so that the surface of the first side 11 of the substrate 1 is flat.

[0054] Optionally, the present application provides a waterproof structure, wherein the sealing layer 3 is a solidified sealing paste, which is formed by filling the sealing paste to a specified depth in the sealing groove 13 and then curing the sealing paste to form the sealing layer 3, which has a good sealing effect. The backfill layer 4 is a solidified polymer waterproof mortar, and the fluid polymer waterproof mortar is filled into the sealing groove 13 until it is flush with the surface of the first side 11 of the substrate 1, and the backfill layer 4 is formed after the polymer waterproof mortar is cured. The backfill layer 4 is formed by curing the polymer waterproof mortar, which has good structural strength and a relatively rough surface after curing, which can effectively improve the bonding strength between the sealing layer 3 and the waterproof coating 7 described below, so that the backfill layer 4 is reliably combined with the sealing layer 3 and the waterproof coating 7 described below.

[0055] like Figure 1As shown, the waterproof structure provided by the present application, wherein the substrate 1 has a side surface 14, and the side surface 14 is connected between the first side 11 surface of the substrate 1 and the second side 12 surface of the substrate 1; according to the use requirements, the substrate 1 has a certain thickness, and the greater the thickness of the substrate 1, the larger the area of ​​its side surface 14.

[0056] The waterproof membrane 2 also includes a fourth portion 24 and a fifth portion 25. The fourth portion 24 is connected to the edge of the third portion 23 away from the second portion 22, and the fifth portion 25 is connected to the edge of the fourth portion 24 away from the third portion 23. That is, the first portion 21, the second portion 22, the third portion 23, the fourth portion 24 and the fifth portion 25 are connected in sequence to form the entire waterproof membrane 2; the fourth portion 24 covers the side surface 14, and the fifth portion 25 covers the second side 12 surface of the substrate 1, so as to completely cover the second side 12 surface and the side surface 14 of the substrate 1, thereby realizing overall waterproofing of the substrate 1.

[0057] like Figure 1 As shown, the waterproof structure provided by the present application further includes a wall 6 and a waterproof coating 7.

[0058] The wall 6 is vertically connected to the base plate 1.

Along the second direction Y, the wall 6 has an outer side 61 and an inner side 62, corresponding to the outside and inside of the building.

[0059] Since the waterproof membrane 2 is laid on the outer side 61 of the building, the sealing groove 13 is located on the outer side 61 of the wall 6. After the waterproof membrane 2 is folded upward from the second side 12 surface of the substrate 1 and the side surface 14 of the substrate 1 to the first side 11 surface of the substrate 1, it is positioned in the sealing groove 13.

[0060] The waterproof coating 7 is applied to the outer surface 61 of the wall 6 and a portion of the first side 11 of the substrate 1 located on the outer side 61 of the wall 6 to form a continuous waterproof coating 7, and the waterproof coating 7 is sealed with the waterproof membrane 2 to achieve external waterproofing of the entire waterproof structure.

[0062] The connection between the waterproof coating 7 and the waterproof coiled material 2 is sealed by a sealing member 8 , which is formed by curing the sealing paste to ensure the sealing of the connection between the waterproof coating 7 and the waterproof coiled material 2 .
