Description
Technical field
The utility model is related to concrete strength inspection instrument, more particularly to a kind of concrete bouncing back instrument.
Background technology
Concrete bouncing back instrument is adapted to detect for common buildings component, bridge and various concrete components(Plate, beam, column, crane span structure)It is strong
Degree, hints on operation are to ensure that reisilometer axis and concrete test face are vertical always, firmly uniformly slowly, righting alignment test
Face, it is slow to promote, it is fast to read.
Such as the patent of Publication No. CN202548023U, a kind of high strength concrete resiliometer is disclosed, there is elastic hammer, bullet
Tension spring, elastic stem, centre pilot are hit, wherein for elastic stem from front end sleeve on centre pilot, elastic hammer quality is 370g, attack
Tension spring rigidity is 785N/m, and elastic tension spring tensile elongation is 75mm, a diameter of 15mm of elastic stem, and nominal impulse energy is
2.207J, described elastic stem is equipped with multiple, and each elastic stem length and diameter is identical and to hit the radius of curvature of end face different.
Above-mentioned high strength concrete resiliometer is when manual operation is detected, it is difficult to the axis of reisilometer be made to be surveyed with concrete
Examination face is vertical always, and measurement can be made to generate larger human error.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of concrete bouncing back instrument, have
The advantages of reducing artificial measurement error.
The above-mentioned technical purpose of the utility model technical scheme is that:
A kind of concrete bouncing back instrument, including reisilometer ontology, be provided on the outer wall of the reisilometer ontology for its with
The vertical supporting rack in concrete test face, support frame as described above include the first mounting plate and the second installation for mutually including an angle setting
Plate and be arranged on the second mounting plate and with the first mounting plate ring stand disposed in parallel, the ring stand is set in reisilometer sheet
On body.
So set, be pushed against on concrete test face by the first mounting plate, i.e. the first mounting plate and concrete test
Face is arranged in parallel, and with closing being arranged in parallel for the first mounting plate and ring stand, then reisilometer ontology is pushed against coagulation across ring stand
On native test surfaces, under the circumferential limit of ring stand so that reisilometer ontology is in vertical state with concrete test face, at this time
As long as pushing against supporting rack and reisilometer ontology on concrete test face, prevent sidesway can guarantee reisilometer ontology axis and
Concrete test face is vertical always, reduces the error artificially measured.
Further preferably:The limitting casing unidirectionally slided for limiting reisilometer ontology is provided on the ring stand, it is described
Limitting casing is oppositely arranged with the first mounting plate.
So set, since reisilometer ontology is in measurement process, to be pushed against with concrete test face always, pass through limit
Frame carries out limitation reisilometer ontology and unidirectionally slides, i.e., along ring stand axially upper unidirectional sliding, when reisilometer ontology and concrete are surveyed
Examination face abuts, and limitting casing can prevent reisilometer ontology under vibration, back falling back, ensure the accuracy of measurement data;And
It need not artificially help reisilometer ontology, survey crew that can push against supporting rack emphatically on concrete test face, reduce
The possibility of supporting rack offset, while the possibility of this solid offsetting of reisilometer is reduced, reduce the error artificially measured.
Further preferably:It is offered on first mounting plate opposite with reisilometer ontology for limiting reisilometer ontology
The limit hole of shake.
So set, since ring stand is limited limitation reisilometer ontology shake, by being arranged on the first mounting plate
Limit hole forms the cooperation of upper and lower ends limitation with ring stand so that the measurement end of reisilometer ontology is not easy inclined because of shake
It moves, ensures that the axis of reisilometer ontology and concrete test face are vertical always, reduce the error artificially measured.
Further preferably:The elastic component for providing reisilometer ontology elastic-restoring force is provided in the limit hole,
The elastic component includes the rubber pad being set in limit hole.
So set, due to that can be detached from limit hole for reisilometer ontology, the ratio that the diameter of limit hole can be arranged is sprung back
More greatly, thus under the position-limiting action of limitting casing, there is reisilometer body ends in limit hole for instrument body end diameter
The case where shake, lead to the inaccuracy of measurement data, and pass through the setting of spring element, i.e. rubber pad so that reisilometer body end
Portion is pushed against in limit hole, and the possibility of this solid offsetting of reisilometer is reduced, and reduces the error artificially measured, while will not shadow
Ring the removal to reisilometer body end.
Further preferably:The elastic component includes along the circumferentially disposed elastomeric spring of limit hole and being set to elasticity
Abutting head on spring for being pushed against with reisilometer ontology, the abutting head is between adjacent rubber pad.
So set, by the way that elastomeric spring is arranged and pushes against the setting of head, in two layers of abutting form, head was pushed against before this to support
Tightly, the shake of reisilometer ontology is consumed;When the shake of reisilometer ontology is larger, then is added by rubber pad and push against capitiform circlewise
Elastic component, improve the deficiency of single rubber pad setting limit and damping, further decrease the possibility of this solid offsetting of reisilometer,
Reduce the error artificially measured.
Further preferably:First mounting plate and the second mounting plate are vertically arranged, and the ring stand is slidably mounted on
On two mounting plates, the locating part for limiting ring stand sliding is provided on second mounting bracket.
So set, due to there are having the case where certain distance between the first mounting plate and concrete test face, cause
DATA REASONING is inaccurate, is slided along the second mounting plate by ring stand so that reisilometer body end is supported with concrete test face
Tightly, measurement error is reduced.
Further preferably:The locating part includes the threaded rod being rotatably installed in the second mounting plate and across ring stand,
The threaded rod is threadedly coupled with ring stand.
So set, by rotating threaded rod, ring stand is circumferentially limited in the second mounting plate so that ring stand is along second
The length direction of mounting plate moves, and is moved towards the first mounting plate direction so that reisilometer body end and concrete test
Face pushes against.
Further preferably:It is provided with sand paper on second mounting plate and ring stand forward surface.
So set, due on concrete test face there is the different situation of carbonizing degree, there is uneven,
During this bulk measurement of reisilometer, the data of this bulk measurement of reisilometer can be caused not correspond to whole, and may be single
The data of point cause measurement data not have effect, or cause measurement error bigger, by the scouring of sand paper so that coagulation
Native test surfaces are smooth, improve the accuracy of measurement data.
In conclusion the utility model having the beneficial effect that in contrast to the prior art:Pass through the setting of supporting rack so that return
Playing instrument ontology can keep vertical with concrete test face, and the limit hole on the first mounting plate, and forming both ends circumferentially limits, drop
The low possibility for leading to this solid offsetting of reisilometer due to the shake of reisilometer ontology;Coordinate the elasticity in upper limit hole simultaneously
Part is further decreased since the shake of reisilometer ontology leads to the influence of DATA REASONING inaccuracy.
