The beam structure damage monitoring device provided by the utility model is simple in structure, low in cost and easy to operate and can be used for monitoring the normal working condition of the beam structure for a long time.
Description
Technical field
The utility model relates to a kind of structure damage monitoring device, is specifically related to a kind of girder construction damage monitoring device, belongs to civil engineering work checkout equipment technical field.
Background technology
Girder construction is modal a kind of member in industry and the covil construction, as highway, railroad bridge, and Vierendeel girder, canopy beam etc.Because be subjected to the influence of long duration load and environmental corrosion etc., crackle equivalent damage situation will inevitably appear in girder construction, must these degree of impairments be monitored accurately, so that the on-call maintenance reinforcing, thereby the consequence of averting a calamity property takes place.
Traditional damage monitoring method such as ultrasonic method, methods of magnetic field, temperature field method etc., all require probably to know in advance damage position, and require detected position equipment to arrive, so anticipation is relatively poor, workload expends height greatly, so be not suitable for the damage monitoring of large scale civil engineering structure.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel girder construction damage monitoring device, to overcome described defective of the prior art.
The utility model content
For addressing the above problem, it is a kind of simple in structure, with low cost that the purpose of this utility model is to provide, and easy operating is implemented, and can make the girder construction damage monitoring device of long term monitoring to the working healthily situation of girder construction.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of girder construction damage monitoring device, and it is used for the degree of impairment of monitoring beam, and it comprises mass, no linear movement pick-up, data acquisition instrument and damage monitoring device; Wherein, described mass is arranged on the beam and can moves at beam; Described no linear movement pick-up is arranged on the beam, itself and the wireless connections of data acquisition instrument; Described damage monitoring device is connected with the data acquisition instrument.
Girder construction damage monitoring device of the present utility model further is set to: the weight of described mass be beam weight 1/10 ~ 1/20.
Girder construction damage monitoring device of the present utility model further is set to: described beam is specially semi-girder, and described no linear movement pick-up is arranged on the free end of semi-girder.
Girder construction damage monitoring device of the present utility model also can be set to: described beam is specially free beam, and described no linear movement pick-up is arranged on the span centre position of free beam.
Compared with prior art, the utlity model has following beneficial effect: girder construction damage monitoring apparatus structure of the present utility model is simple, with low cost, and easy operating is implemented, and it can make long term monitoring to the working healthily situation of girder construction.

Embodiment
See also shown in the Figure of description 1, it is first embodiment of girder construction damage monitoring device of the present utility model, it is used for the degree of impairment of monitoring beam 9, and it is made up of several parts such as mass 1, no linear movement pick-up 2, data acquisition instrument 3 and damage monitoring devices 4.In the present embodiment, described beam 9 is specially a free beam 9.
Wherein, described mass 1 is arranged on the beam 9 and can moves at beam 9.The weight of described mass 1 be beam 9 weight 1/10 ~ 1/20.
Described no linear movement pick-up 2 is arranged on the beam 9, itself and 3 wireless connections of data acquisition instrument.Specifically, described no linear movement pick-up 2 is arranged on the span centre position of free beam 9.
Described damage monitoring device 1 is connected with data acquisition instrument 3.
The principle of work of girder construction damage monitoring device of the present utility model is as follows:
At first, by placing a movably mass 1 at beam 9, utilize the gravity of this mass 1 that beam 9 is carried out the static(al) loading, move this mass 1 one by one according to certain movement law then, realize that beam 9 is carried out repeatedly static(al) to load; Secondly, utilize no linear movement pick-up 2 and data acquisition instrument 3 to gather the amount of deflection parameter that each mass 1 moves the back rest 9 key position places, regularly (as every month once) repeated said process and gathered the amount of deflection parameter; At last, the amount of deflection parameter that will gather every adjacent two phases can be monitored out beam 9 whether to damage the position of damage and the order of severity by damage monitoring device 4 successively.
See also shown in the Figure of description 2, it is second embodiment of girder construction damage monitoring device of the present utility model, it is used for the degree of impairment of monitoring beam 9 ', it also is made up of several parts such as mass 1 ', no linear movement pick-up 2 ', data acquisition instrument 3 ' and damage monitoring devices 4 ', the difference of itself and first embodiment is: described beam 9 ' is specially semi-girder 9 ', and described no linear movement pick-up 3 ' is arranged on the free end of semi-girder 9 '.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
