Description
Technical field
The invention belongs to bridge static loading test, carry out bridge displacement particularly to a kind of static load action appointment position on bridge and measure auxiliary device.
Background technology
Bridge static loading test is that static load action position of specifying on bridge is tested the parameters such as the static displacement of structure, static(al) strain, crack, thus infers bridge structure service behaviour under load action and use ability.Deflection of bridge structure test is one of important parameter to bridge superstructure detection and condition state, by the amount of deflection situation of loading test test bridge structure, reflects the rigidity situation of bridge structure with this, thus judges the health status of bridge.
At present, in bridge static loading test, it is to use dial gauge (displacement transducer) test that displacement structure measures most common method.Under bridge structure, i.e. set up stable support, support is fixed dial gauge (displacement transducer), being contacted with bridge bottom surface by the feeler lever of dial gauge (displacement transducer), the amount of deflection that bridge produces under each load case effect is measured to by the synchronization deformation of feeler lever.When using dial gauge (displacement transducer) to carry out deflection metrology, setting up support needs to expend substantial amounts of human and material resources, especially when under-clearance is higher, set up support and set up difficulty, tester needs in work high above the ground, completes the work such as installation, test, and risk is bigger.Additionally, the stability of support is difficult to ensure that, deflection test result can be caused bigger error, measuring accuracy it cannot be guaranteed that.
Summary of the invention
For setting up the deficiency of stent Methods, it is an object of the invention to provide a kind of do not set up support in the case of use displacement transducer to carry out bridge displacement measurement device.
The technical solution used in the present invention is:
Bridge displacement measures auxiliary device, and this device includes being fixed on rigidity " ┐ " the type fixing device on test girder, rigid cord, well-bucket, displacement transducer；Described rigidity " ┐ " type fixing device is connected with well-bucket by rigid cord and is made rigid cord be in complete straight condition, and described displacement transducer is arranged on the lower section of well-bucket.In the present invention, rigidity " ┐ " type fixing device can use cloud stone glue to stick at displacement measurement, it is possible to use other modes are fixed.It is easy to the installation of whole device and uses and remove.
The operation principle of the present invention: use nonelastic rigid cord outstanding as displacement Transfer Medium, rigid cord upper end uses rigidity rigidity " ┐ " type fixing device to be fixed on bottom bridge at displacement measuring points, one well-bucket of rigid cord lower end lifting, rigid cord can be stretched by the weight of well-bucket completely, the general about 10-50kg (stretching as standard completely with rigid cord) of well-bucket weight, if producing displacement bottom bridge at displacement measuring points, will there is same displacement in well-bucket.Now, only need to measure the displacement that well-bucket produces, i.e. understand the displacement at displacement measuring points bottom bridge.
Further, above-described bridge displacement measures auxiliary device, also includes that well-bucket arrangement for adjusting height, described rigid cord (3) are connected by well-bucket arrangement for adjusting height with well-bucket.The problem need to tied a knot in order to avoid fixing rigid cord in the present invention, use a kind of well-bucket arrangement for adjusting height using frictional force to fix rigid cord, this device adopt can fast and stable fix rigid cord, the most then greatly facilitate the regulation of rigid cord lower end well-bucket height.
Further, above-described bridge displacement measures auxiliary device, also includes displacement transducer fixing device, and displacement transducer is arranged on the lower section of well-bucket by displacement transducer fixing device.Arranging one in the present invention bottom well-bucket can the displacement transducer fixing device of stable holding displacement transducer, displacement transducer is arranged in this displacement transducer fixing device, displacement feeler lever is contacted with ground motionless reference point, when being subjected to displacement at displacement measuring points bottom bridge, it is arranged on the displacement transducer bottom well-bucket to synchronize to be subjected to displacement, now, then displacement can be measured.
Further, above-described bridge displacement measures auxiliary device, and described well-bucket arrangement for adjusting height is provided with rigid cord automatic line receiver.In order to make the repeatable utilization of rigid cord in the present invention, use a rigid cord automatic line receiver storage rigid cord.
Further, above-described bridge displacement measures auxiliary device, and described displacement transducer is provided with displacement feeler lever.
Further, above-described bridge displacement measure auxiliary device, also include with displacement feeler lever with the use of displacement location datum plate.The effect of displacement location datum plate is to withstand displacement feeler lever.Its effect is exactly an indeformable datum mark.
Further, above-described bridge displacement measures auxiliary device, and described displacement transducer is dial gauge displacement transducer.Displacement transducer is the general designation of a kind of equipment measuring displacement, and dial gauge is one therein, and the bridge displacement of the present invention is measured inside auxiliary device, and the displacement transducer of any principle is all available, is not limited to dial gauge.
The method have the advantages that
1. this device uses simple, and cost is relatively set up support and greatly reduced, and needs to carry out work high above the ground, but easily reclaims after having tested, it is not necessary to work high above the ground during installation.
2. the problem need to tied a knot in order to avoid fixing rigid cord in the present invention, use a kind of well-bucket arrangement for adjusting height using frictional force to fix rigid cord, this device adopt can fast and stable fix rigid cord, the most then greatly facilitate the regulation of rigid cord lower end well-bucket height.
3., in order to make the repeatable utilization of rigid cord in the present invention, use a rigid cord automatic line receiver storage rigid cord.
4. in the present invention, rigidity " ┐ " type fixing device can use cloud stone glue to stick at displacement measurement.It is easy to the installation of whole device and uses and remove.
5. arranging one in the present invention bottom well-bucket can the displacement transducer fixing device of stable holding displacement transducer, displacement transducer is arranged in this displacement transducer fixing device, displacement feeler lever is contacted with ground motionless reference point, when being subjected to displacement at displacement measuring points bottom bridge, it is arranged on the displacement transducer bottom well-bucket to synchronize to be subjected to displacement, now, then displacement can be measured.
