Description
Technical field
This utility model relates to combinative structure field, especially relates to a kind of multiple stress state equivalent loading test device for hanging of glued joint.
Background technology
In combinative structure, bonding connection technology is increasingly being applied in engineering construction.Compared with bolt and Stud connection, bonding connection can reduce the engineering time, reduce fastener to save weight, to transmit more load and provide better long-term behaviour.Bolt connection frequently results in substantial amounts of stress and concentrates, and is therefore easy to produce crack.And bonding connection has better adaptability for materials, because the area of contact is bigger, thus reducing stress.
The test studying glued joint mechanical property at present mainly has beam test and push out test two kinds.Test specimen used by beam test is very big, extremely time-consuming takes a lot of work, and it is complicated to test interior joint stress, causes loading that cost is high, test data measuring accuracy is not enough, so the quantity used is fewer and feweri.Although the size of test specimen has been simplified in push out test, make result of the test more credible, but simple pure shear stress state or simple tension stress state can only be simulated, have significant limitation.And this utility model assay device has, and repeatability is high, simple to operate, the measurement of main experimental parameter is accurate, can simulate the advantages such as multiple stress state on test specimen of the same race, it is possible to make the research of glued joint more accurately and comprehensively.
Chinese patent CN103604621A discloses the charger of a kind of test space structure node Hysteresis Behavior, it includes cushion block, cushion block is provided with chute, first loading disc and the second loading disc parallel interval are arranged, it is fixedly linked by attachment structure between first loading disc and the second loading disc, first loading disc and the second loading disc can be moved along loading direction by the pulley being arranged on bottom two loading discs in chute, the axis direction of pulley and the axis direction of the first loading disc and the second loading disc are vertically arranged, the direction that the axis direction of the first loading disc and the second loading disc applies power with jack is consistent, first loading disc or the second loading disc are provided with the jack attachment structure being connected with jack, first loading disc and the second loading disc are provided with the otic placode connecting scalable drag-line.The stress of this patent two set chargers researchs owing to adopting is different, can only analog node one direction stress, and the application can the multi-direction stress of analog node；Secondly, the content of two set charger tests is different, and this patent is applicable to the test of node Hysteresis Energy, it is necessary to node is back and forth loaded, and the application is applicable to the test of glued joint intensity, only needs single load.Therefore, exist can not the defect of the multi-direction stress of analog node for this patent.
Utility model content
The purpose of this utility model is contemplated to overcome the defect that above-mentioned prior art exists and the multiple stress state equivalent loading test device for hanging of glued joint providing a kind of repeatability high, simple to operate.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of multiple stress state equivalent loading test device for hanging of glued joint, including:
Fixed block group: include fixed block and lower fixed block, above-mentioned fixed block connects glued joint test specimen；
Load plate group: be connected to the both sides of fixed block group, be connected with charger；
Connection group: include the high-strength bolt of high-strength bolt and connection fixing block group and the glued joint test specimen connecting load plate group and fixed block group.
Described upper fixed block and the side of lower fixed block are equipped with the bolt hole being connected with load plate group.
The lower surface of described upper fixed block is provided with the fixture connecting glued joint test specimen.
The upper surface of described lower fixed block is provided with the fixture connecting glued joint test specimen.
Described fixture is the angle steel in strap bolt hole, it is also possible to be other fixture matched with glued joint.
Described load plate group is made up of four pieces of semicircle load plate, and two pieces of load plate match and constitute a plectane, are connected to the side of fixed block group, and other two pieces of load plate match and constitute a plectane, are connected to the opposite side of fixed block group.
Compared with prior art, this utility model has the advantage that
One, this glued joint multiple stress state equivalent loading test device for hanging can simulate multiple stress state, and only need adjustment member bolt position just can change stress state, and there is the advantage that repeatability is high, simple to operate, it is possible to make the research of glued joint more accurately and comprehensively；
Two, relative to other tradition load test form, this assay device significantly reduces glued joint size and material for test consumption, not only increases the precision that test is required, and reduces fabrication and installation cost, accelerates test speed, has significantly high practicality.
