DETAILED DESCRIPTION

[0025] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] As Figures 1-4 shown, the utility model provides a novel UPVC rainwater pipe 3 connecting interface, mainly including gutter 1, rainwater head 2, UPVC rainwater pipe 3 and fastening assembly 4. Wherein gutter 1 and rainwater head 2 all adopt steel structure to make, gutter 1 is recessed groove shape, and its bottom is fixedly installed with funnel-shaped rainwater head 2 through welding. One end of UPVC rainwater pipe 3 is equipped with socket 31, and is connected with steel rainwater head 2 through thread. The fastening assembly 4 is sleeved on the outside of socket 31, and includes throat clamp 41 and pipe clamp 42 for radially tightening the interface. The present connecting interface can realize the stable connection between steel rainwater head 2 and UPVC rainwater pipe 3, ensure that the connecting place has good sealing performance, and effectively prevent the loosening phenomenon in the long-term use.

[0027] In the embodiment, one end of the UPVC rainwater pipe 3 is provided with an outwardly expanding socket 31 that is adapted to the steel rainwater head 2. The inner wall of the socket 31 is provided with an internal thread 33, and the outer wall of the steel rainwater head 2 is provided with a mating external thread 34. The UPVC rainwater pipe 3 and the steel rainwater head 2 are threadedly connected into one body. A rubber sealing ring 32 is provided at the interface to prevent water leakage. The UPVC rainwater pipe 3 is made by factory prefabrication. In order to ensure the stability of the connecting interface, the length d of the socket 31 segment is at least 50 mm.

[0028] In this embodiment, the fastening assembly 4 includes a collar 41 and a pipe collar 42 sleeved outside the socket 31. The collar 41 can radially tighten the joint and mainly includes a fastening bolt 412, a fastening nut 411 and a collar band 413. The fastening bolt 412 and the fastening nut 411 are fixedly installed on the collar band 413, and the tightness of the collar band 413 can be adjusted by rotating the fastening bolt 412. When the fastening bolt 412 is tightened, the collar band 413 is tightened and closely fitted to the outer wall of the socket 31, which can effectively prevent the connection interface from loosening. The pipe collar 42 is designed in a cylindrical structure, and its inner diameter is slightly larger than the outer diameter of the socket 31, so it can be sleeved outside the socket 31. It not only limits the outward deformation of the UPVC rainwater pipe 3 interface due to thermal expansion, but also provides all-round protection for the connection interface.

[0029] In this embodiment, considering the impact and corrosion of rainwater in the actual use environment, the collar 41 and the pipe collar 42 are made of corrosion-resistant stainless steel material. In order to improve the stability of the connection interface, two collars 41 are arranged in a spaced manner and sleeved on the upper end and the lower end of the socket 31, and the pipe collar 42 is arranged between the two collars 41. Such arrangement can effectively prevent the pipe collar 42 from falling off. A flexible buffer layer is also arranged between the pipe collar 42 and the outer wall of the socket 31, which is specifically a sponge pad 5. It not only plays a buffering role when the UPVC rainwater pipe 3 expands due to heat, but also prevents the stainless steel pipe collar 42 from directly contacting the surface of the UPVC rainwater pipe 3 and causing scratches. After the collar 41 and the pipe collar 42 are tightened, waterproof glue is applied to the gap of the outer circle of the connection interface to form an outer waterproof sealing layer, further improving the waterproof performance.

[0030] In this embodiment, as shown in Figure 4 , the connection interface structure between the two UPVC rainwater pipes 3 is the same as the connection method between the UPVC rainwater pipe 3 and the steel rainwater hopper 2. Both are first fixed by threaded sleeve connection, and then tightened by collars 41 and pipe collars 42. The construction is very convenient, which can significantly shorten the construction period and greatly improve the construction efficiency.

[0031] In this embodiment, the specific construction process is as follows:

[0032] 1. First, prefabricate the new UPVC rainwater pipe 3 and the steel rainwater hopper 2 in the factory, and process the corresponding threads on the UPVC rainwater pipe 3 and the steel rainwater hopper 2.

[0033] 2. Sleeve the socket 31 of the UPVC rainwater pipe 3 outside the steel rainwater hopper 2, then install two collars 41 and a pipe collar 42 outside the connection interface, and finally apply waterproof glue to the gap of the connection joint to prevent water leakage.

[0034] 3. Continue to sleeve the subsequent pipe section at the tail end of the UPVC rainwater pipe 3 until the drain outlet, and complete the installation and construction of the entire drainage system.

[0035] The embodiments described above are only part of the embodiments of the present application, rather than all the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative labor are within the scope of protection of the present application.
