Embodiment

[0032] Embodiment (taking the resistance signal as an example)

[0033] Such as Figure 1 to Figure 4 As shown, the specific embodiment is: a mechanically connected internal steel bar joint spacing monitoring device, including a signal sensor module 3, a signal sensing module 4, a wire 6, a mobile power supply 7 and a monitoring display 5, and the signal sensor module 3 is provided with two One and respectively movably installed on the two outer steel bars of the mechanical connector, the signal sensor is connected with the signal sensing module 4, mobile power supply 7 and monitoring display 5 through the wire 6 and cooperates with the mechanical connector to form a closed loop.

[0034] Wherein, the signal sensor module 3 collects the resistance signal through the area between the two signal sensor modules 3, and the collected resistance can be obtained according to the formula R=ρL / S, (ρ represents the resistivity of the butt steel bar 2, and L represents that electrons pas...

Abstract

The invention discloses a mechanical connection inner reinforcement joint spacing monitoring device and an operation method, and belongs to the field of building construction. A signal sensor module, a signal induction module and a monitoring display are arranged, the signal sensor module is used for conducting signal collection on the connecting sleeve and the butt-joint reinforcing steel bars which are electrified, and if a gap is reserved in the connector, the resistance at the moment can be ideally explained as the distance between the two butt-joint reinforcing steel bars and the corresponding signal sensor module. If no gap exists, the voltage/resistance signals are voltage/resistance values corresponding to the distances between the two butt-joint reinforcing steel bars and the corresponding signal sensor modules, the signal sensor modules can identify, analyze and process whether the voltage/resistance values are set values or not, and then a buzzing alarm mechanism of a monitoring display is used for warning or not. The problem that in the prior art, defects exist in the aspect of monitoring and early warning of the distance between the mechanical connection inner steel bar connectors can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device and an operation method for monitoring the distance between steel bar joints in mechanical connections. Background technique [0002] During building construction, the construction quality of the steel structure plays a very important role in the safety of the overall structure. At present, mechanical connections are mostly used for the lap joints of steel bars, and serious quality problems are likely to occur if the mechanically connected steel bar joints are not properly constructed or improperly operated by workers. Problem, if the concealed project is not properly inspected, it may cause inestimable economic losses. After searching, no patents, books, papers and technical documents related to technical problems have been found. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies in the prior art, so a d...
