Abstract

A prefabricated assembly grouting sleeve capable of monitoring grouting fullness and stress variation and a manufacturing method thereof. The prefabricated assembly grouting sleeve comprises a grouting sleeve body, a fiber bragg grating sensor and an interrogator. The two ends of the grouting sleeve body are both reinforcing steel bar inserting ends, two end ports of the grouting sleeve body are provided with a sealing ring and a sealing end cover correspondingly, and the sealing end cover and the grouting sleeve body are connected through threads. A grouting opening and a slurry outlet are formed in the side faces of the two ends of the grouting sleeve body. A positioning pin and an aligning pin are arranged in the middle of the grouting sleeve body. The fiber bragg grating sensor is arranged on one side of the slurry outlet, and the fiber bragg grating sensor is in circuit connection with the interrogator through an outgoing cable. According to the prefabricated assembly grouting sleeve, the grouting fullness can be monitored during engineering construction, the bearing condition of the prefabricated assembly building and the environmental temperature and humidity variation can be monitored in real time according to needs in the using and maintaining process, and a reliable basis is provided for maintaining and safety of the building.

Description

technical field [0001] The invention relates to a steel bar connecting device and a manufacturing method thereof, in particular to a prefabricated assembled grouting sleeve capable of monitoring grouting fullness and stress changes and a manufacturing method thereof. Background technique [0002] With the rapid development of the industrialization of my country's construction industry, the prefabricated concrete structure has become the main direction of the industrialization of the construction industry due to its advantages of short construction period, less on-site construction work, energy saving and environmental protection. In prefabricated concrete structures, the connection quality of prefabricated components directly affects the safety of concrete building structures. Therefore, the connection technology of prefabricated components, especially the connection technology of prefabricated steel bars has attracted more and more attention. [0003] Reliable connection of...
