Thread-off proof clamp for flexible bell socket cast-iron drain pipe

Abstract

The invention relates to a thread-off proof clamp for a flexible bell socket cast-iron drain pipe, and belongs to a device used for construction cast-iron drain pipelines. By means of the thread-off proof clamp for the flexible bell socket cast-iron drain pipe, the technical problems in the prior cast-iron drain pipes that water leakage is caused by the falling off of pipe conjections, loading capacity is low and high-rise buildings cannot be used are solved. According to the technical scheme, the thread-off proof clamp for the flexible bell socket cast-iron drain pipe comprises a locking bolt, a nut and a thread-off proof clamp, wherein the thread-off proof clamp is composed of at least two single-piece clamps, the single-piece clamp is a circular arc groove-type body with fastening teeth, the fastening teeth are arranged at the upper end and the lower end of the inner side of the circular arc groove-type body, fastening clamping lugs are arranged at two sides of the circular arc groove-type body, and a fixed clamping lug is arranged in the middle portion of the outer side of the circular arc groove-type body. The thread-off proof clamp for the flexible bell socket cast-iron drain pipe has the advantages that the structure is simple, the size is compact, the installation is easy, the installation space is saved, the construction cost is reduced and the safety of the pipe conjections is improved.

Description

technical field [0001] The invention relates to a detachment-preventing clamp for a cast iron drainage pipe with a flexible socket interface, which belongs to a detachment-preventing device for a cast iron drainage pipe joint of a building. Background technique [0002] At present, the most commonly used flexible socket interface cast iron pipe for building drainage is a pipe interface socket, and the pipe is connected by sealing rubber ring, flange and bolt compression interface. This pipe is safe for general building sewer installations. However, in some pressurized rainwater drainage pipes and some joints of pipelines that are subjected to large water flow gravity, impact force and mechanical force, the phenomenon that the pipe joints often fall off often occurs. This not only brings safety hazards to the installation and use of pipelines, but also affects the application of cast iron pipes with flexible socket interfaces on rainwater pipelines in high-rise buildings. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the technical problems of the existing cast iron drainpipes that the pipe joints are easy to fall off, resulting in water leakage, low pressure bearing capacity and unusable high-rise buildings, and to provide a cast iron drainpipe that prevents the cast iron drainpipe from falling off, has high pressure bearing capacity and strong connection strength. Good and can make high-rise buildings use flexible socket interface cast iron drainage pipe with anti-off clamp
