[0018] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.
[0019] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0020] Embodiment 1
[0021] As Figure 1-2As shown in the figure, a casing tool for a roof rainwater outlet includes a first casing 1, a second casing 2, and a connecting plate 3. The diameter of the first casing 1 is larger than that of the second casing 2. One end of the first casing 1 is fixed with a connecting plate 3, and the second casing 2 is fixed to the end of the connecting plate 3 away from the first casing 1. The connecting plate 3 is an annular plate, and the outer diameter of the connecting plate 3 is the same as the outer diameter of the first casing 1, and the inner diameter of the connecting plate 3 is the same as the inner diameter of the first casing 1. Two layers of antirust paint layers 4 are applied to the outside of the connection between the first casing 1 and the connecting plate 3 and the outside of the connection between the second casing 2 and the connecting plate 3. A waterproof layer 5 is applied to the inner wall surfaces of the first casing 1, the connecting plate 3, and the second casing 2.
[0022] Embodiment 2
[0023] Based on the structure of Embodiment 1, in Embodiment 2, as Figure 3 shown, a pouring port 6 is provided at one side edge of the connecting plate 3 where the second casing 2 is connected. Two pouring ports 6 are symmetrically provided, making the pouring of the grouting material more uniform.
[0024] The connecting plate 3 is fixedly installed on the original roof rainwater pipe (not shown in the figure), and the second casing 2 is located inside the original roof rainwater pipe. Grouting material is poured between the second casing 2 and the original roof rainwater pipe.
[0025] A plurality of connecting protrusions 7 are circumferentially fixed on the outer wall of the second casing 2, which can enhance the connection strength with the grouting material.
