Description
Technical field
The present invention relates to a kind of Bridge Testing Equipment, topple hazards monitoring and alarm for beam bridge more particularly, to a kind of
Equipment.
Background technology
During the use of bridge, in order to avoid bridge topple cause any property loss and life harm, generally to bridge
Structure be improved or reinforce that bridge is avoided to topple.Such as Chinese patent CN103205927A discloses a kind of bridge and resists and inclines
Bridge pier supporting device is covered, Single column pier bridge in the prior art is solved support base is easy to cause using single point supporting beam and come to nothing, even
The problem of capsizing case occurs.Chinese patent CN103452053A discloses a kind of antidumping bracing means of Single column pier bridge,
Include only column bridge pier, widening structure is set in the upper end of only column bridge pier, the top of the widening structure is provided with branch
Seat.A kind of antidumping bracing means for Single column pier bridge that the invention provides, is limited in space under bridge or condition does not allow situation
Under, steel lid beam is added by the way that Single column pier intermediate to continuous box girder is wide, changes on steel lid beam and sets double support, pass through setting for double support
It puts, unbalance loading influence is reduced on straight bridge, twisting moment can be improved effectively for curved, skew bridge, improve bridging apparatus stress,
Reduce security risk.
As described in two patents above, currently in order to bridge is avoided to topple, mainly studied in terms of structure improvement,
And lack to the monitoring of bridge overturning stability and alarm technique.Beam bridge structure in the past since bridge side load is excessively concentrated and
Make the lateral stressed imbalance of structure, bridge beam body is caused to be toppled to side.It is by tying whether to have the danger toppled
What the characteristics of structure itself and external influence codetermined.
The design feature of every beam bridge is different, external influence also constantly changes, the branch that certain methods pass through measurement structure
The modes such as the carload on seat counter-force, beam body displacement, inclination angle and bridge floor obtain structure overturning stability indirectly.For above-mentioned
Measurement method and measuring apparatus not only also need to complicated installation and maintenance by very high request to power supply, are needed after data are obtained
Will after largely analyzing could evaluation structure overturning stability, monitoring cost is high.
Chinese patent CN104034248A discloses the real-time radio monitoring device that a kind of early warning bridge integrally topples, including
Babinet, slide rheostat, fixed protective resistance, the pressure measuring instrument with signal projector part, power supply, beam sides fixed plate,
Girder limiting plate and displacement montant, babinet connect bolt by bridge pier and are fixed on bridge pier, slide rheostat, fixed protective resistance
And the pressure measuring instrument with signal projector part is arranged in babinet, slide rheostat, fixed protective resistance and power supply series connection
Forming circuit, the pressure measuring instrument with signal projector part are connected in parallel on the both ends of slide rheostat, and beam sides fixed plate passes through
Beam sides fixing bolt is fixed on girder, and girder limiting plate is connected with beam sides fixed plate bending, the connection of displacement montant one end
On girder limiting plate, the sliding end connection of the other end and slide rheostat.But above-mentioned real-time radio monitoring device structure compared with
For complexity, cost of manufacture height.
Beam bridge is large number of at present, and with greater need for a kind of monitoring device of convenient practicality, monitoring bridge integrally topples stabilization
Property, and to the equipment that the bridge for being likely to occur the problem of toppling is alarmed, to find Dangerous Bridge in time and to be handled.
