Description
Technical field
The utility model relates to pick-up unit field, laboratory, specifically, specially refers to a kind of bolt tension pick-up unit.
Background technology
Along with a large amount of constructions of skyscraper, bridge etc., steel construction is used more and more.Because connecting, bolt has easy construction, the strength of joint advantages of higher, and steel structure node often adopts bolt to connect in the structural design.But research at present is abundant inadequately to bolt group internal force distribution understanding, shortage realizes detecting in real time to bolt strained state and the effective ways of monitoring, and detection and the monitoring with large-scale important structure connection reliability carried out in the correlative study that is unfavorable for the steel structure bolt connected node.How real-time, the accurate and effective bolt strained state of measurement is problem demanding prompt solution in scientific research and the engineering practice.
The utility model content
The purpose of this utility model is at deficiency of the prior art, and the device of the bolt strained situation of quick, the accurate and effective measurement of a kind of energy is provided.
The technical matters that the utility model solves can realize by the following technical solutions:
A kind of bolt tension pick-up unit is characterized in that: it comprises movable part, fixed part and pedestal, and described fixed part is arranged at the below of movable part, and fixed part is fixedly installed on the pedestal that is positioned at its bottom; The end of described fixed part and movable part is equipped with bayonet socket, and the bayonet socket of fixed part and movable part is located along the same line.
Further, described bayonet socket comprises the annulus that is positioned at fixed part or movable part center and the chute that is communicated with annulus, and an end of described chute is communicated with annulus, and the other end of chute is hatch frame.
Further, the side of described movable part and fixed part offers observation panel.
Compared with prior art, the beneficial effects of the utility model are as follows:
Simple in structure, design ingenious, can quick, accurate and effective measurement the device of bolt strained situation.
Description of drawings
Fig. 1 is the structural representation of bolt tension pick-up unit described in the utility model.
Number in the figure explanation: 100. movable parts, 200 fixed parts, 300. pedestals, 400. bayonet sockets, 410. observation panels
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1, a kind of bolt tension pick-up unit described in the utility model, it comprises movable part 100, fixed part 200 and pedestal 300, and described fixed part 200 is arranged at the below of movable part 100, and described fixed part 100 is fixedly installed on the pedestal 300 that is positioned at its bottom; The end of described fixed part 200 and movable part 100 is equipped with bayonet socket 400, and the bayonet socket 400 of fixed part 200 and movable part 100 is located along the same line.
It should be noted that, for the ease of installing and the fixing test bolt, described bayonet socket 400 comprises the annulus that is positioned at fixed part 200 or movable part 100 centers and the chute that is communicated with annulus, and an end of described chute is communicated with annulus, and the other end of chute is hatch frame.By adopting the said structure design, the bolt that need detect can easily be put into the detection position.
In addition, be pointed out that also that the side of described movable part 100 and fixed part 200 offers observation panel 410.By adopting this kind design, can find to test the deformation situation of bolt in testing process intuitively, promptly and accurately obtain experimental data.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
