Abstract
The utility model discloses a novel bearing beam load tester which comprises a counterforce steel beam and a test beam, wherein two ends of the test beam are respectively fixedly connected with two steel frames, each steel frame is moveably connected with a corresponding end of the counterforce steel beam by a fastener, and the test beam is provided with one or a plurality of jacks; and a maximum load prompt system is also disposed on the counterforce steel beam, the maximum load prompt system comprises a displacement sensor, the displacement sensor is connected with an illumination circuit through an analog switch, and the displacement sensor and the analog switch are connected with a power source. The novel bearing beam load tester has the advantages that the demand of large-scale load tests can be satisfied under the action of a plurality of jacks, and the load test precision can be effectively raised by the maximum load prompt system.
Description
Technical field
The utility model relates to building engineering field, especially a kind of New type weight loading beam loading test device.
Background technology
At building engineering field, need to do situ loading to built good engineering, especially about the loading test of spandrel girder, in order to guarantee the fiduciary level of engineering structure.But existing spandrel girder load test method can only be used in the little situation of load mostly, even can not satisfy the demand of large-scale loading test, in addition, existing load test method precision is also limited.
The utility model content
The utility model technical assignment is for above-mentioned technical deficiency, and a kind of New type weight loading beam loading test device is provided.
The technical scheme that the utility model technical solution problem adopts is: New type weight loading beam loading test device, comprise counter-force girder steel and test beam, described test beam two ends are fixedly connected with respectively a steelframe, described each steelframe is flexibly connected by the two ends of securing member and counter-force girder steel simultaneously, described test beam is provided with one or more lifting jack, also be provided with the peak load prompt system on the described counter-force girder steel, described peak load prompt system comprises displacement transducer, and this displacement transducer is connected with lighting circuit by analog switch.
The beneficial effect that the utility model can bring is:
1, can satisfy the demand of large-scale loading test;
2, Effective Raise the precision of loading test.
Description of drawings
Fig. 1, the utility model one-piece construction schematic diagram;
The structural representation of peak load prompt system in Fig. 2, the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done following detailed description:
As depicted in figs. 1 and 2, the New type weight loading beam loading test device that the utility model is announced, comprise counter-force girder steel 1 and test beam 5, described test beam 5 two ends are fixedly connected with respectively a steelframe 6, described each steelframe 6 is flexibly connected by the two ends of securing member 3 with counter-force girder steel 1 simultaneously, described test beam 5 is provided with one or more lifting jack 4, constantly lifting jack 4 is extended upwardly during measurement, lifting jack 4 upper surfaces and counter-force girder steel 1 lower surface are in contact with one another, counter-force girder steel 1 namely moves up under the effect of lifting jack 4, be subjected to displacement, when lifting jack 4 not when extending upward, counter-force girder steel 1 also no longer moves up, at this moment the power sum of all lifting jack 4 is exactly the peak load of counter-force girder steel 1, because the effect of power is mutual, so the peak load of counter-force girder steel 1 also is the peak load of test beam 5.
In order to improve the precision of loading test, on described counter-force girder steel 1, also be provided with peak load prompt system 2, described peak load prompt system 2 comprises displacement transducer 7, this displacement transducer 7 is connected with lighting circuit 10 by analog switch 9, and displacement transducer 7 is connected with analog switch and is all connected power supply 8, when not reaching peak load, counter-force girder steel 1 will move up under the effect of lifting jack 4, be subjected to displacement, and then displacement transducer 7 sends signal, lighting circuit 10 work; When reaching peak load, counter-force girder steel 1 just can not move up under the effect of lifting jack 4, and displacement transducer 7 just can not send signal like this, and then lighting circuit 10 quits work, and in time reminds people to arrive peak load, has improved the precision of loading test.
