All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] Please refer to Figures 1-5 , the present invention provides a technical solution: a leakage prevention and waterproof structure at the building junction, including:

[0044] A side wall member 1, on the upper end surface of which an embedded support plate 11 is provided;

[0045] A first waterproof coiled material 2, which is coated on the upper end surface of the side wall member 1. One end of the first waterproof coiled material 2 is provided with a first bent portion. A first storage groove for storing the first bent portion is provided on the side wall member 1. The embedded support plate 11 penetrates through the first waterproof coiled material 2;

[0046] An inclined top surface member 3, the bottom of which contacts the upper end surface of the side wall member 1, and the embedded support plate 11 contacts the back surface of the inclined top surface member 3;

[0047] A second waterproof coiled material 4, which is coated on the bottom surface of the inclined top surface member 3. A plurality of second metal support sheets 41 arranged in parallel are provided on the second waterproof coiled material 4. A first step surface is provided on the side wall of the inclined top surface member 3, and a second step surface is provided on the bottom surface of the first step surface. A second bent portion is provided on one side of the second waterproof coiled material 4, and the second bent portion is stored in the second step surface;

[0048] The anti-leakage profile 5 is fixedly installed on the side wall member 1. A bending portion 51 is provided on the upper side of the anti-leakage profile 5, and the bending portion 51 is arranged within the first stepped surface;

[0049] The water collecting trough 6 is arranged below the bending portion 51, and one end of the water collecting trough 6 is connected to the discharge pipe 61;

[0050] The inner support member 7 is fixedly installed on the side wall member 1.

[0051] A backing plate 12 is provided on the back surface of the embedded support plate 11. The first locking bolt 71 passes through the inner support member 7 and the backing plate 12 and is then fixedly installed on the embedded support plate 11. The embedded support plate 11 is fixed to the inner support member 7 and supported by the backing plate 12, effectively supporting the inclined top surface member 3.

[0052] Working principle: At the junction of the side wall member 1 and the inclined top surface member 3, the first waterproof coiled material 2 and the second waterproof coiled material 4 are respectively wrapped on the upper end surface of the side wall member 1 and the bottom surface of the inclined top surface member 3, effectively preventing leakage between the side wall member 1 and the inclined top surface member 3. Taking the second waterproof coiled material 4 as an example, when the second waterproof coiled material 4 wraps the bottom surface of the inclined top surface member 3, on the one hand, through the bending of the second metal support piece 41, it is made to fit the bottom surface of the inclined top surface member 3, ensuring the bonding quality of the second waterproof coiled material 4 to the inclined top surface member 3 through the adhesive. On the other hand, the second bending portion of the second waterproof coiled material 4 is received within the second stepped surface, not exceeding the inclined top surface member 3 and not affecting the installation of the anti-leakage profile 5. Similarly, for the first waterproof coiled material 2, a first metal support piece is provided to improve the bonding quality, and when the first waterproof coiled material 2 is installed, it is positioned by using the embedded support plate 11, further ensuring the installation quality of the first waterproof coiled material 2 and having a good anti-leakage and waterproof effect. The outside of the junction of the side wall member 1 and the inclined top surface member 3 is drained by the anti-leakage profile 5 to prevent rainwater from entering the junction. The rainwater flows down through the metal anti-leakage profile 5 into the water collecting trough 6, and the water flows into the discharge pipe 61 through the drain holes on the bottom surface of the water collecting trough 6 and is then discharged, further improving the waterproof effect.

[0053] Embodiment 2

[0054] On the basis of the above embodiment, the following improved technical solutions are further made in this embodiment: An inner diversion groove 62 is arranged in the water collecting tank 6. The cross-section of the inner diversion groove 62 is arc-shaped, and the inner diversion groove 62 is arranged obliquely. The bottom of the inner diversion groove 62 is arranged in the water collecting tank 6 in a suspended manner through a support block. The water flowing down along the anti-leakage profile 5 first falls into the inner diversion groove 62. When the drainage volume is small, the inner diversion groove 62 with an arc-shaped cross-section can effectively collect and gather the water flow and quickly discharge it. When the water flow is large, the water flow will overflow from the inner diversion groove 62 into the water collecting tank 6, and the inner diversion groove 62 and the water collecting tank 6 drain water at the same time. The height of the inner diversion groove 62 gradually decreases toward the discharge pipe 61, guiding the liquid in the groove body to the discharge pipe 61 for quick drainage and preventing water from accumulating in the water collecting tank 6.

[0055] An extension edge 511 is arranged at the bottom of the bent portion 51, and the extension edge extends above the inner diversion groove 62, so as to better guide the water flow into the inner diversion groove 62 and improve the drainage speed.

[0056] Embodiment 3

[0057] On the basis of the above embodiment, the following improved technical solutions are further made in this embodiment: The inner diversion strip 8 is inserted into the gap between the inner support member 7 and the inclined top surface member 3. An arc-shaped diversion surface is arranged on the inner diversion strip 8, and the bottom end of the arc-shaped diversion surface extends above the inner support member 7. The arrangement of the inner diversion strip 8 can divert the liquid on the inner surface of the inclined top surface member 3 away from the side wall member 1 through the arc-shaped diversion surface to achieve waterproofing. At the same time, the bottom end of the arc-shaped diversion surface extends above and beyond the inner support member 7 to prevent water from flowing onto the surface of the inner support member 7 and causing corrosion of the first locking bolt 71.

[0058] A second locking bolt 72 is arranged on the inner support member 7. The second locking bolt 72 is threadedly connected to the inner support member 7, and the end of the second locking bolt 72 extends into the inner diversion strip 8. The inner diversion strip 8 is detachably installed for easy replacement. At the same time, the inner diversion strip 8 is effectively positioned by the second locking bolt 72 to ensure the diversion effect.

[0059] Embodiment 4

[0060] On the basis of the above embodiment, the following improved technical solutions are further made in this embodiment: An installation groove 13 is arranged on the side wall member 1, and a connection strip 52 corresponding to the installation groove 13 in position is arranged on the back surface of the anti-leakage profile 5. The cross-section of the connection strip 52 is trapezoidal.

[0061] The anti-leakage profile 5 is fixedly installed in the installation groove 13 of the side wall member 1 through the connection strip 52 on the back surface. An adhesive material such as cement mortar can be filled in the installation groove 13. Since the cross-section of the connection strip 52 is trapezoidal, the connection strip 52 can be effectively prevented from detaching from the installation groove 13, improving the installation stability of the anti-leakage profile 5.

[0062] Example 5

[0063] On the basis of the above embodiments, the following technical solutions for improvement are further made in this embodiment: a hanging groove 53 is provided on the anti-leakage profile 5, and the hanging groove 53 extends into the anti-leakage profile 5 to the connecting strip 52. A hanging plate 63 with a shape matching the hanging groove 53 is provided on the back surface of the water collecting tank 6. The hanging plate 63 on the back surface of the water collecting tank 6 is inserted into the hanging groove 53 and fixed by bonding. The hanging groove 53 extends into the anti-leakage profile 5 to the connecting strip 52, so that the depth of the hanging groove 53 is large, improving the connection strength of the water collecting tank 6.

[0064] As mentioned above, only the specific preferred embodiments of the present invention are described, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
