Bar member deformation monitoring device and scaffolding monitoring alarm system

Abstract

The invention discloses a bar member deformation monitoring device. The device comprises a rigid rod (1), a power supply (2) and a signal generator (3). Two ends of the rigid rod (1) is respectively provided with a first fixing fastener (4) and a second fixing fastener (5), wherein the first fixing fastener (4) and the second fixing fastener (5) are capable of being fixedly connected to a bar member to be measured respectively; the first fixing fastener (4) and/or the second fixing fastener (5) is provided with a first electrode (6) capable of being electrically contacted with the bar member to be measured; the middle of the rigid rod (1) is provided with a monitoring fastener (7); a monitoring hole (8) is arranged on the monitoring fastener (7), wherein the bar member to be measured can runs through the monitoring hole (8) and keeps a ring gap with the monitoring hole (8); the monitoring fastener (7) is provided with a second electrode (9) in the inner circumference of the monitoring hole (8) along the circumferential direction; the power supply (2) and the signal generator (3) are in series connection between the first electrode (6) and the second electrode (9). The bar member deformation monitoring device can monitor the deformation of the bar member in real time, is simple and convenient to install, and economical and reliable. The invention also provides a scaffolding monitoring alarm system.

Description

technical field [0001] The invention belongs to the technical field of bar deformation monitoring, in particular to a bar deformation monitoring device and a scaffold monitoring and alarm system. Background technique [0002] At present, with the large-scale construction of high-rise buildings, large industrial plants, underground projects, bridges and other buildings, the application of scaffolding formwork engineering has increased day by day. However, some construction companies do not pay attention to the safety role of scaffolding formwork engineering in construction, resulting in scaffolding collapse. Accidents continue to occur, which not only affect the quality of the project, construction progress and project cost, but also affect the safety of people's lives and property. [0003] The main reasons for the collapse of scaffolding are as follows: 1) The material of the scaffold does not meet the requirements of the specification; 2) The erection of the scaffold does ...

AI Technical Summary

Problems solved by technology

[0004] At present, the deformation of the rod is generally monitored by sticking the strain gauge on the rod manually. Although this method can play a monitoring role, the installation workload is heavy due to the relatively high requirements for the mounting of the strain gauge.
