A sleeve-type scaffolding engineering safety early warning device using double measurement means

Abstract

The invention relates to a sleeve-type scaffold engineering safety early-warning device employing dual measurement means. A force transfer rod group is welded with a lower end of a scaffold connectionpiece, an upper annular sleeve and a lower annular sleeve wrap an outer side of the force transfer rod group, the upper annular sleeve and the lower annular sleeve are connected by a connection softsleeve, a string-type resistance wire group is arranged on a resistance wire installation plate and is placed in the upper annular sleeve and the lower annular sleeve, a piezoelectric crystal is arranged on a piezoelectric crystal installation plate and is placed in the lower annular sleeve, the string-type resistance wire group and the piezoelectric crystal are connected with a signal input end of a signal processing module by wires, the signal processing module is used for processing an electrical signal and then transferring the electrical signal to a sound-light alarm by a signal output end, the sound-light warning device is used for warning in case of emergency, and the device is prevented from being damaged by a protection bolt during the transportation and installation process.

Description

technical field [0001] The invention belongs to the field of scaffolding engineering, and in particular relates to a sleeve-type scaffolding engineering safety warning device using double measuring means, which is applied to the yielding safety warning of straight rods under pressure of scaffolding. Background technique [0002] Building construction safety is the top priority in construction production. With the emergence of more and more high-rise buildings, the use of scaffolding is increasing, and safety issues are becoming increasingly prominent. On May 21, 2013, the Sichuan Tuojiang No. 3 Bridge collapsed, killing 6 people; on July 24, 2011, Hefei Hefei Hehua Road viaduct jacking accident, killing 1 person; on January 12, 2010, the Kunming Airport stent collapsed, 7 people died; on June 27, 2008, the Yongwen Railway mobile formwork accident killed 7 people. These accidents have seriously endangered the safety of people's lives and property and the progress of engineer...

Problems solved by technology

[0005] At present, domestic scaffolding safety early warning devices mainly include a scaffold safety early warning system such as the authorized publication number CN106840265A, and a safety early warning system for scaffold settlement observation and settlement measurement such as the authorized publication number CN106705933A and other invention patents. These inventions mainly use lasers, infrared sensors, etc. , to monitor the deformation of the scaffold and the settlement of the foundation. The installation and debugging process is complicated, and it is greatly affected by environmental conditions, such as dust, temperature, etc., and the use conditions are limited. At present, for the convenience of installation and disassembly in China, the deformation of the steel pipe of the scaffold is carried out. There are not many devices with direct monitoring and strong anti-interference ability research and development, so it is necessary to propose a sleeve-type scaffolding engineering safety early warning device using dual measurement methods
