Description

Technical Field

[0001] The invention relates to the technical field of pipe body fastening, and in particular to a supporting pipe body fastening device for municipal building construction engineering. Background Art

[0002] Municipal construction projects refer to construction projects led or supervised by the government with urban infrastructure as the core content. Its scope covers the planning, construction and maintenance of urban public facilities and municipal supporting facilities, aiming to improve urban service functions and the quality of life of residents. The water supply and drainage systems, gas pipelines, heat pipe networks, communication lines, etc. in municipal construction projects need to be connected through pipelines, and the installation of the pipe body requires fastening equipment to support the pipe body.

[0003] A Chinese patent with the announcement number CN116792567B discloses a supporting pipe body fastening device for road construction engineering. It includes a supporting ring body and a fastening ring body, wherein the fastening ring body is arranged on the top of the supporting ring body, and a connecting mechanism is arranged at the connecting position between the supporting ring body and the fastening ring body, and the supporting ring body and the fastening ring body are connected by the connecting mechanism to form an opening and closing structure. In the present invention, the inner diameter of the fastening ring body is set to be larger than the inner diameter of the supporting ring body to ensure that the pipe body has enough adaptability space after being offset in the supporting ring body, and multiple adaptability mechanisms are arranged on the fastening ring body. When the opening and closing structure is closed, the adaptability mechanism is used to adapt to the outer wall contour of the pipe body in the slide groove, so as to ensure that the deformed part can be compensated by the active adaptability mechanism, thereby improving the stability of the fastening.

[0004] However, the above technical solution has the following shortcomings: the self-tightening mechanism pushes the bonding plate to limit the tube body through the connecting spring. On the one hand, it is impossible to adjust the pre-tightening force of the bonding plate on the tube body. If the pre-tightening force is too tight, it will cause inconvenience to the installation. If the pre-tightening force is too loose, the stability of the fastening of the pipe fitting cannot be guaranteed. On the other hand, the setting of the connecting spring has a very limited limiting ability for the tube body. When the tube body vibrates due to the fluid being transported in the tube body, the entire adaptation mechanism will also vibrate with the vibration of the tube body, and the tube body cannot be fastened.
