Description
Technical field
This utility model belongs to science of bridge building technical field of measuring equipment, it particularly relates to quickly measure bridge to one
Beam support comes to nothing the measuring instrument of degree.
Background technology
Bridge pad is to be set up on pier, the device of end face supporting bridge superstructure.Its function is transmission top knot
The counter support power of structure, counter support power includes vertical force and horizontal force.During building a bridge, it is desirable to girder must be with a seated connection
Touch closely knit, dead in line, it is impossible to occur setting up beam body and bearing break-off.Common at hollow slab bridge, box girder bridge, T beam bridge etc.
In packaged type bridges, every single-beam arranges four bearings, and the seat empty of lesser extent causes partial pressing to increase, anti-at load
Under multiple effect, girder produces vibration, affects the serviceability of bridge, also can reduce the stability of girder.The bearing that degree is serious
Come to nothing, beam body certainly will be caused to be become 3 even 2 supports, the change of beam body restraint condition by four-point supporting, have a strong impact on beam
Body stress performance, long term then can produce beam body failure by shear, damages beam body, shortens bridge whole service life.Bearing takes off
It is impaired that sky further results in bridge floor, pier, expansion joint.
In final acceptance of construction handed over by conventional bridge and routine is made regular check on, only the bearing degree of coming to nothing is done qualitative description,
As: seriously coming to nothing or slightly come to nothing, the degree of depth of not coming to nothing bearing highly carries out quantitatively and accurately judging with coming to nothing.According to
Specification is defined as ensureing the normal work of bearing, beam body, and the bearing come to nothing is answered steel plate or the wedge shape of cushioning respective thickness
Steel plate processes, but the physical dimension of steel plate and wedge-shaped steel plate cannot precisely determine, only does and substantially judges, causes seat empty to process
Poor effect.
