A structural steel bar stress coupling connector and method for connecting and continuously monitoring structural steel bar stress

Abstract

The invention discloses a constructional reinforcement stress coupling connector and a method for connecting and continuously monitoring constructional reinforcement stress. The constructional reinforcement stress coupling connector comprises a nut column, two connectors in threaded connection with two ends of the nut column, and locknuts matched with the connectors. The nut column and the left and the right connectors at the two ends are respectively matched through right-hand threads and left-hand threads respectively; the connectors are connected to the constructional reinforcements, then the nut column is screwed to apply pulling stress to the constructional reinforcements; and the locknuts matched with the connectors can lock the constructional reinforcements, so as to realize the stress coupling connection of the constructional reinforcements. When a reinforcement meter arranged on the constructional reinforcements is broken and replaced, the connector can be used to apply the pulling stress to the constructional reinforcements and enables the starting value of the new reinforcement meter to be the original measured value, thereby continuously monitoring the constructional reinforcement stress.

Description

technical field [0001] The invention relates to a structural reinforcement stress coupling connector and a method for connecting and continuously monitoring the structural reinforcement stress, which is mainly used for the stress coupling connection of concrete structural reinforcement, underground cavern reinforcement grid arch frame, etc., that is, after the structural reinforced reinforcement is cut off When reconnecting, the stress of the steel bar is restored to the original level, so that the concrete structure or the steel support structure maintains the original state or stress distribution. Background technique [0002] Due to the complexity of the geological conditions of the surrounding rock of the underground cavern, it must be supported in engineering, including bolt support, reinforced concrete lining support, steel arch support, steel grid arch support and so on. In order to understand the deformation and stability process of the surrounding rock of the cavern...

AI Technical Summary

Problems solved by technology

[0009] In order to overcome the shortcomings of the existing technology that the stress of the original structural steel bars cannot be restored after the steel bar meter is damaged, the present invention aims to provide a structural steel bar stress coupling connector, which is mainly used for engineering structural steel bar stress coupling connections. That is to say, when the reinforced steel bars of the structure are cut off and then connected, the stress of the steel bars can be restored to the original level, so that the concrete structure or steel support structure can maintain the original state or stress distribution.
