[0015] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further described in detail below in combination with the drawings and specific embodiments.It should be explained that the embodiment of the present application and the features in the embodiment can be combined mutually without conflict.

[0016] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description, therefore, the protection scope of the utility model is not limited by the following disclosed specific embodiments.

[0017] The following will be combined Figs. 1-2 The building concrete prefabricated slab of the embodiment of the utility model is specifically explained.

[0018] As Fig. 1 , Fig. 2As shown, the present invention proposes that the present invention is implemented through the following technical solution: a building concrete precast panel, comprising a plurality of transversely spliced ​​precast panels and a waterproofing tape 6 bonded between each pair of precast panels. The precast panel comprises a precast panel body 1, wherein the precast panel body 1 comprises a mixture of foamed cement and polystyrene particles in a ratio of 1:4-5, which provides a soundproofing effect. Calcium silicate board layers 2 are fixedly bonded to the upper and lower ends of the precast panel body 1. The provision of the calcium silicate board layers 2 provides thermal insulation, thereby achieving excellent thermal insulation and broadening the application range of the device. The other side of the calcium silicate board layer 2 is fixedly bonded to a first waterproof layer 4, and the other side of the first waterproof layer 4 is fixedly bonded to a second waterproof layer 5. The material of the prefabricated board body 1 is a mixture of foamed cement and polystyrene particles. The calcium silicate board layer 2 and the first waterproof layer 4 are the same width, and the second waterproof layer 5 is narrower than the calcium silicate board layer 2 and the first waterproof layer 4. The left and right ends of the second waterproof layer 5 are both 2 cm shorter than the first waterproof layer 4. The first waterproof layer 4 is made of polyvinyl acetate, and the second waterproof layer 5 is made of polyurethane. The provision of the waterproof layer protects the prefabricated board from water seepage and other problems that affect the performance of the prefabricated board. In addition, the two layers of waterproof layer greatly enhance its waterproof performance, thereby improving the practicality of the device to a certain extent.

[0019] The waterproof sticker 6 includes an integrally formed arc-shaped solid long plate 61 and a solid long plate 62. The solid long plate 62 is located at the bottom center of the arc-shaped solid long plate 61. The width of the arc-shaped solid long plate 61 is 6 cm, and the width of the solid long plate 62 is 4 cm. The material of the waterproof sticker 6 is made of TPO waterproof membrane. TPO waterproof membrane refers to thermoplastic polyolefin waterproof membrane, which is a sheet-shaped thermoplastic rubber elastic waterproof material with ethylene resin as the base material, using advanced polymerization technology and a specific formula. TPO waterproof membrane not only plays a waterproof role, but also can isolate water vapor, control humidity, and reduce the impact of ambient temperature and humidity on the insulation layer. Using TPO waterproof membrane as the waterproof layer material is more advanced than traditional waterproof membrane in terms of waterproof performance, material mechanical properties, green environmental protection, and recyclability. The lower surface of the waterproof tape 6 is bonded with an adhesive layer. The waterproof tape 6 is symmetrically bonded to the left and right ends of the two prefabricated panels. The lower surface of the solid long panel 62 is bonded to the first waterproof layer 4, and the lower surface of the curved solid long panel 61 is bonded to the second waterproof layer 5. The use of hot-press lamination technology allows the waterproof surface layer 3 and the waterproof main layer 4 to be glued and bonded simultaneously, achieving a stronger composite. The waterproof tape 6 is therefore applied to the joints of the prefabricated panels, preventing dirt and water from accumulating in the joints, further preventing water ingress and effectively improving production efficiency.

[0020] Working process: When in use, the upper and lower layers of calcium silicate board layers 2 of the prefabricated board body 1 have a heat preservation effect, and the two waterproof layers on the other side of the calcium silicate board layer 2 make it waterproof, avoiding water seepage and thus extending the service life of the prefabricated board. The waterproof sticker 6 is affixed to the joints of the prefabricated board to avoid dirt and water retention in the joints, further preventing water ingress and effectively improving production efficiency.
