DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the range of protection of the utility model.

[0023] Example 1: a drainage pipe fitting for building settlement joint, including straight pipe with socket and telescopic sleeve, as shown in Figures 1 to 4 Telescopic sleeve 8 includes telescopic sleeve main body 81, sealing rubber ring 82 and locking flange 83, one end of telescopic sleeve main body is provided with socket with flange head 84, the other end is provided with integrated structure flange 85 and socket short pipe 86;One end of straight pipe with socket 7 is inserted into telescopic sleeve 8, sealing rubber ring 82 is installed in the middle of locking flange 83 and the upper part of flange head 84 of telescopic sleeve main body, and is fixed by bolt locking, to seal and connect straight pipe with socket 7 and telescopic sleeve 8, the distance between the bottom of straight pipe with socket and the bottom of telescopic sleeve has displacement;The other end of straight pipe with socket is used for connecting other drainage pipe fittings, and the socket short pipe of telescopic sleeve can be inserted into other flange socket pipe fittings and fixed and sealed.

[0024] Straight pipe with socket can be extended to the distance 5mm from the bottom of telescopic sleeve in telescopic sleeve, and the bottom of straight pipe with socket and telescopic sleeve has displacement of 5mm-300mm or even more, to facilitate the telescopic length adjustment of telescopic sleeve. The pipe diameter of socket short pipe of telescopic sleeve is equal to the pipe diameter of the straight pipe with socket, to facilitate drainage. The other end of straight pipe with socket is provided with straight pipe flange head, to facilitate the connection of other drainage pipe fittings.

[0025] The flange head and the flange plate of the telescopic sleeve 8 are provided with a bevel, which is beneficial to the arrangement of the sealing rubber ring and helps to seal the socket straight pipe and the telescopic sleeve by the sealing rubber ring. The flange plate at the other end of the telescopic sleeve is provided with a bevel, which can support the pipe.

[0026] Embodiment 2: A drainage system for a building settlement joint as shown in Figures 1 to 3 The drainage system is arranged between a vertical wall 2 with a settlement joint 1 and a building plane 3. The vertical pipe 4 of the drainage system is connected to the discharge horizontal pipe 6 through a 90-degree elbow 5. The drainage pipe is connected between the discharge horizontal pipe 6 and the elbow 7 at the building settlement joint. The socket straight pipe 7 of the drainage pipe is fixed to the vertical wall 2. The telescopic sleeve is fixed to the building plane 3. The socket short pipe 86 of the telescopic sleeve 8 is inserted into the socket of the discharge horizontal pipe 6 of the flanged socket pipe and is sealingly connected.

[0027] In Embodiment 2, the socket straight pipe 7 of the drainage pipe and the telescopic sleeve 8 can also be arranged on the discharge horizontal pipe. The socket straight pipe is fixed to the vertical wall, and the telescopic sleeve is displaced along with the socket straight pipe due to settlement. The displacement of the building plane is large during settlement, and the displacement of the vertical wall is small and can be ignored.

[0028] In Embodiment 2, the settlement joint generates a horizontal settlement force, which stretches the discharge horizontal pipe. The discharge horizontal pipe is fixed to the building plane 3, and the pulling force is greater than the sealing force between the telescopic sleeve and the socket straight pipe. The telescopic sleeve is displaced along the socket straight pipe, and the sealing rubber ring is always sealed on the socket straight pipe and moves along it. This can resist the damage of the settlement joint and prevent damage to the drainage system. The length of the socket straight pipe inserted into the telescopic sleeve can be designed according to requirements.

[0029] Embodiment 3: A drainage system for a building settlement joint as shown in Figure 1 and Figure 4 The drainage system is arranged between a vertical wall 2 with a settlement joint 1 and a building plane 3. The vertical pipe 4 of the drainage system is connected to the discharge horizontal pipe 6 through a 90-degree elbow 5. The drainage pipe is connected between the vertical pipe 4 and the elbow 7 at the building settlement joint. The socket straight pipe 7 of the drainage pipe is fixed to the vertical wall. The socket short pipe 86 of the telescopic sleeve 8 is inserted into the socket of the elbow 5 of the flanged socket pipe and is sealingly connected. At the same time, the drainage pipe is connected between the discharge horizontal pipe 6 and the elbow 7 at the building settlement joint, and the connection method is the same as that in Embodiment 2.

[0030] In the embodiment 3, the drainage system can resist the vertical and horizontal damage of the settlement joint. The settlement joint produces a downward force to pull the vertical pipe 4, and the straight pipe 7 with the socket joint connected to the vertical pipe is fixed on the vertical wall 2 and cannot move. The downward force is greater than the sealing force between the straight pipe 7 with the socket joint and the expansion sleeve 8 of the vertical drainage pipe, and the expansion sleeve is pulled to move. The sealing rubber ring is always sealed on the straight pipe with the socket joint, which can resist the damage of the settlement joint, prevent the damage of the drainage system, and maintain the sealing property of the drainage system. The horizontal settlement force produced by the settlement joint can pull the horizontal drainage pipe, and the horizontal drainage pipe and the expansion sleeve are fixed on the building plane 3 and sink. The pulling force is greater than the sealing force between the expansion sleeve and the straight pipe with the socket joint, and the horizontal expansion sleeve is displaced along the straight pipe with the socket joint. The horizontal expansion sleeve can resist the damage of the horizontal settlement force, prevent the damage of the drainage system, and maintain the sealing property of the drainage system. The length of the straight pipe with the socket joint inserted into the expansion sleeve can be designed according to the requirement.

[0031] The straight pipe with the socket joint 7 and the expansion sleeve 8 of the drainage pipe can also be separately arranged between the vertical pipes, or separately arranged between the vertical pipe 4 and the elbow 7 at the building settlement joint. The above embodiments are partial embodiments.

[0032] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
