[0036] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0037] like Figures 1 to 4 As shown, this application provides a waterproof prefabricated component 1, wherein the waterproof prefabricated component 1 includes a first plate 11 and a second plate 12 connected to each other, and a first included angle is formed between the first plate 11 and the second plate 12; the first plate 11 and the second plate 12 are integrally formed and connected to ensure the connection strength between the two, thereby ensuring the overall structural strength of the waterproof prefabricated component 1.

[0038] The first plate 11 and the second plate 12 are made of metal to ensure good structural strength.

[0039] The first plate 11 has a first surface 111 and a second surface 112 facing away from each other, and the second plate 12 has a third surface 121 and a fourth surface 122 facing away from each other. The first surface 111 and the third surface 121 are connected, and the second surface 112 and the fourth surface 122 are connected.

[0040] For example, the first surface 111 and the third surface 121 form an angle of less than 180°, and during installation, the first surface 111 and the third surface 121 can be fitted together at the external corner of the foundation 2 of the building; the second surface 112 and the fourth surface 122 form an angle of greater than 180°, and during installation, the second surface 112 and the fourth surface 122 can be fitted together at the internal corner of the foundation 2 of the building.

[0041] Optionally, the specific angle of the first included angle can be adjusted according to the external and internal angles existing on the foundation 2 of the building, but this application is not limited to this.

[0042] The prefabricated waterproof component 1 also includes a waterproof layer 13, which covers the first surface 111 and the third surface 121, and / or covers the second surface 112 and the fourth surface 122. Specifically, the waterproof layer 13 is laid on the side of the prefabricated waterproof component 1 away from the foundation 2 of the building. For example, when the prefabricated waterproof component 1 is installed at the external corner of the foundation 2 of the building, the first surface 111 and the third surface 121 are in contact with the surface of the foundation 2 of the building, and the waterproof layer 13 covers the second surface 112 and the fourth surface 122. When the prefabricated waterproof component 1 is installed at the internal corner of the foundation 2 of the building, the second surface 112 and the fourth surface 122 are in contact with the surface of the foundation 2 of the building, and the waterproof layer 13 covers the first surface 111 and the third surface 121.

[0043] The waterproof prefabricated component 1 provided in this application, by setting a first plate 11 and a second plate 12 with a first included angle, can effectively adhere to and contact the two sides of the inside corner or the two sides of the outside corner at the position of the inside corner or the outside corner. It can clamp the waterproof membrane 23 between the surface of the first plate 11 and the foundation 2 of the building and between the surface of the second plate 12 and the foundation 2 of the building, or make the waterproof membrane 23 cover the first plate 11 and the second plate 12 and fix it to the waterproof layer 13 covering the first plate 11 and the second plate 12, effectively ensuring the effective adhesion of the waterproof membrane 23 to the foundation 2 of the building at the inside corner and the outside corner, thereby reducing the risk of water leakage.

[0044] like Figures 1 to 4 As shown, the waterproof prefabricated component 1 provided in this application includes a waterproof layer 13 comprising a covering portion 131 and an extension portion 132. The covering portion 131 covers the first surface 111 and the third surface 121, or the covering portion 131 covers the second surface 112 and the fourth surface 122, so as to achieve waterproofing of the side surface of the first plate 11 facing away from the foundation 2 of the building and the side surface of the second plate 12 facing away from the foundation 2 of the building.

[0045] The extension 132 is connected to the covering 131, and the extension 132 protrudes from the edge of the first plate 11 away from the edge of the second plate 12 or the edge of the second plate 12 away from the edge of the first plate 11. By providing the extension 132, during the assembly of the waterproof prefabricated component 1, the connection between the waterproof layer 13 and the waterproof membrane 23 covering the part of the building foundation 2 other than the area covered by the first plate 11 and the second plate 12 can be improved, thereby reducing the installation difficulty of the waterproof prefabricated component 1.

[0046] like Figure 3 and Figure 4 As shown, the waterproof prefabricated component 1 provided in this application includes a waterproof layer 13 further comprising a fixing part 133, which is connected to the extension part 132, and the fixing part 133 protrudes from the surface of the first plate 11 away from the waterproof layer 13 or the surface of the second plate 12 away from the waterproof layer 13.

[0047] Optionally, the fixing part 133 is formed by extending and bending the extension part 132 away from the edge of the covering part 131. By setting the fixing part 133, the extension part 132 can be effectively connected to the waterproof membrane 23 laid on the foundation 2 of the building, and the connection area between the extension part 132 and the waterproof membrane 23 can be guaranteed to ensure the sealing and waterproofing effect.

[0048] Optionally, the covering part 131, the extension part 132 and the fixing part 133 are integrally formed and connected to ensure the integrity of the waterproof layer 13, thereby ensuring the waterproof effect of the waterproof layer 13.

[0049] like Figures 5 to 8 As shown, this application also provides a waterproof structure, wherein the waterproof structure includes a base 2, a waterproof membrane 23, and a waterproof prefabricated component 1 as described above.

[0050] The base 2 has a first paving surface 21 and a second paving surface 22 that are in contact with each other. A second included angle is formed between the first paving surface 21 and the second paving surface 22: when the second included angle is less than 180°, it forms a negative angle; when the second included angle is greater than 180°, it forms a positive angle.

[0051] The second included angle is equal to the first included angle formed between the first plate 11 and the second plate 12 of the waterproof precast component 1, and the first plate 11 is parallel to the first paving surface 21, and the second plate 12 of the waterproof precast component 1 is parallel to the second paving surface 22; so as to ensure reliable adhesion between the waterproof precast component 1 and the inside or outside corner of the foundation 2 of the building.

[0052] The waterproof membrane 23 is at least partially laid and covers the first laying surface 21 and the second laying surface 22; the waterproof membrane 23 is sealed and fixedly connected to the waterproof layer 13 of the prefabricated waterproof component 1. The waterproof membrane 23 can be sandwiched between the surface of the first slab 11 and the foundation 2 of the building, and between the surface of the second slab 12 and the foundation 2 of the building, or the waterproof membrane 23 can cover the first slab 11 and the second slab 12 and be fixedly connected to the waterproof layer 13 covering the first slab 11 and the second slab 12, effectively ensuring the effective adhesion of the waterproof membrane 23 to the foundation 2 of the building at the inside and outside corners, thereby reducing the risk of water leakage.

[0053] like Figure 5 and Figure 6 As shown, the waterproof structure provided in this application includes a waterproof membrane 23 divided into two parts. One waterproof membrane 23 is laid on the first laying surface 21, and a portion of the waterproof membrane 23 is sandwiched between the first board 11 and the first laying surface 21. The other waterproof membrane 23 is laid on the second laying surface 22, and a portion of the waterproof membrane 23 is sandwiched between the second board 12 and the second laying surface 22. In this case, the waterproof layer 13 covers the surface of the first board 11 facing away from the first laying surface 21 and the surface of the second board 12 facing away from the second laying surface 22. Specifically, if it corresponds to the external corner of the foundation 2 of the building, the waterproof layer 13 covers the second surface 112 and the fourth surface 122. If it corresponds to the internal corner of the foundation 2 of the building, the waterproof layer 13 covers the first surface 111 or the third surface 121.

[0054] like Figure 5 As shown, the extension 132 of the waterproof layer 13 is bonded and fixed to the waterproof membrane 23 with sealant, and / or, as shown in the figure. Figure 6 As shown, the fixing part 133 of the waterproof layer 13 is sealed and welded to the waterproof membrane 23. This achieves a sealed connection between the prefabricated waterproof component 1 and the waterproof membrane 23, ensuring effective waterproofing of the entire surface of the building's foundation 2.

[0055] like Figure 7 As shown, the waterproof structure provided in this application includes a portion of the waterproof membrane 23 laid on the first laying surface 21 and spaced apart from the first board 11, and a portion of the waterproof membrane 23 laid on the second laying surface 22 and spaced apart from the second board 12; that is, similarly, the waterproof membrane 23 includes two pieces, one of which is laid on the first laying surface 21, and the other is laid on the second laying surface 22. Figure 5 and with Figure 6Unlike the embodiments shown, in this embodiment, the waterproof membrane 23 is spaced apart from the first board 11 and from the second board 12, so that the first board 11 and the first laying surface 21 and the second board 12 and the second laying surface 22 are reliably bonded. The waterproof membrane 23 is not laid at the external or internal corners, which can avoid the waterproof membrane 23 from being laid unevenly at the internal or external corners or from being broken or damaged due to bending.

[0056] In this embodiment, the waterproof structure further includes a sealing layer 24. The gaps between the waterproof membrane 23 and the first plate 11, as well as the gaps between the waterproof membrane 23 and the second plate 12, are sealed by the sealing layer 24. The sealing layer 24 is sealed and fixedly connected to the waterproof layer 13 of the waterproof membrane 23 and the first plate 11, or the sealing layer 24 is sealed and fixedly connected to the waterproof layer 13 of the waterproof membrane 23 and the second plate 12, so as to achieve a sealed connection between the waterproof membrane 23 and the waterproof prefabricated component 1.

[0057] like Figure 8 As shown, the waterproof structure provided in this application also includes a method for laying a prefabricated waterproof component 1. Specifically, the first plate 11 is in contact with the first laying surface 21, the second plate 12 is in contact with the second laying surface 22, the waterproof layer 13 covers the surface of the first plate 11 facing away from the first laying surface 21 and the surface of the second plate 12 facing away from the second laying surface 22, and the waterproof membrane 23 is directly laid on the surface of the foundation 2 and covered with the waterproof layer 13, so that the prefabricated waterproof component 1 is embedded between the waterproof membrane 23 and the foundation 2 of the building, and the waterproof membrane 23 and the waterproof layer 13 are sealed and welded together. While ensuring the sealing and waterproofing effect, the integrity of the waterproof membrane 23 and the flatness and integrity of the building appearance are improved.

[0058] like Figures 5 to 8 As shown, in the waterproof structure provided by this application, the first plate 11 and / or the second plate 12 are connected to the foundation 2 through the connector 25. The connector 25 penetrates the first plate 11 or the second plate 12 and is inserted and fixed to the inside of the foundation 2. The waterproof prefabricated component 11 and the foundation 2 of the building are positioned and connected through the connector 25.

[0059] Sealing elements 26 are provided on the surface of the first plate 11 facing away from the foundation 2 and on the surface of the second plate 12 facing away from the foundation 2. The sealing elements 26 cover the connector 25 at the penetration position of the first plate 11 and the second plate 12 to seal the position and prevent the installation of the connector 25 from causing water leakage in the waterproof prefabricated component 1.

[0060] like Figure 9As shown, the waterproof structure provided in this application includes a sealing element 26 comprising a first sealing part 261, a second sealing part 262, and a connecting part 263. The connecting part 263 connects the first sealing part 261 and the second sealing part 262. The first sealing part 261, the second sealing part 262, and the connecting part 263 are integrally formed to ensure structural strength. The first sealing part 261 connects to the first plate 11 and covers the position where the connecting part 25 penetrates the first plate 11. The second sealing part 262 connects to the second plate 12 and covers the position where the connecting part 25 penetrates the second plate 12. Thus, a single sealing element 26 can seal two penetration positions. The connecting part 263 limits the movement of the first sealing part 261 and the second sealing part 262, reducing the possibility of seal failure due to movement between them.

[0061] Optionally, the area of ​​the connecting part 263 is smaller than the area of ​​the first sealing part 261 and the area of ​​the second sealing part 262, so as to reduce its material cost while realizing the connecting function of the connecting part 263.
