The warning system of high-supported formwork Real-Time Monitoring
Technical field
The utility model relates to construction project field, especially the warning system of high-supported formwork Real-Time Monitoring.
Background technology
Terminological interpretation:
High-supported formwork: full name high and big die plate support system, according to defining in " the construction project high and big die plate support system construction safety supervision and management guide rule " of house and the issue on Dec 26th, 2009 of town and country construction portion: high and big die plate support system refers to that engineering construction on-site concrete component template bearing height exceedes 8m, or set up span and exceed 18m, or construction total load (TL) is greater than 15kN/ ㎡, or concentration line load is greater than the formwork bracing system of 20kN/m.And each is local for guaranteeing safety, promulgate local severeer limit standard, as built [1998] No. 27 literary compositions of prison according to Guangdong, Guangzhou, high-supported formwork refers to highly be more than or equal to template and the support system thereof of 4.5m.This monitoring system can require difference that corresponding pre-, alert if is set respectively according to each place regulations.
Real-Time Monitoring: the Real-Time Monitoring that native system refers to refers to and adopts sensor to carry out synchronous variation of automatically measuring each parameter to the whole process of pouring concrete, maintenance and form removal on high-supported formwork.
Monitoring parameter: refer to that native system sensor gathers the value that judges use as analyzing, as characterized distortion, amount of deflection, inclination and the vibration of high-supported formwork system, internal force, strain, inclination and the sedimentation of vertical rod, the internal force of cross bar, strain and inclination.Monitoring variable responds for comparing, analyze with the limit value of setting and judging to trigger the corresponding Forecast and Warning of native system.
UPS(Uninterruptible Power System/Uninterruptible Power Supply): i.e. uninterrupted power source, be that accumulator (mostly being plumbic acid maintenance-free accumulator) is connected with main frame, by modular circuits such as main frame inverters, direct current converted to the system equipment of civil power.
High-supported formwork caves in engineering construction accident, occupies higher ratio always.High-supported formwork security incident is mainly that high-supported formwork carries excessive or is out of shape the excessive steel component failure in system of bringing out, and high-supported formwork partial collapse or entirety occurs and topple, and then cause pouring concrete operating personnel injures and deaths.Along with the sustained and rapid development of economic society, being showing improvement or progress day by day of architecture science technology, scale, space and the scale of construction of construction work are progressively rising tendency, plane figure, the structure type of buildings are also more complicated various, and the buildings of large span, heavy in section beam and high spatial is had higher requirement to high-supported formwork Safety Management.
In high-supported formwork construction, mainly carry out artificial deformation's monitoring at present, arrange special messenger at the peripheral optical detection measuring appratus that adopts of the first floor, in casting concrete process, implement Real-Time Monitoring, monitoring frequency be 20 ~ 30 minutes once.In the time that Monitoring Data approaches or reaches alarming value, organize immediately interested party to take emergent or emergency measure, superior relevant department report simultaneously.But for the observation of high-supported formwork inside, because high-supported formwork internal rod is closeer, outside optical instrument is difficult to observation.Manually enter high-supported formwork inside and observed Personal Risk infeasible.In addition, the existing method of high-supported formwork safety does not realize Real-Time Monitoring, and safety monitoring can not cover whole high-supported formwork work progress.The finally contact between three links of construction-observation-emergency measure is slower, the security situation that the workman in construction cannot perception high-supported formwork, once occur that observed reading transfinites, it is slower that the startup of corresponding emergency measure is also reacted.
