Description
Technical field
The utility model relates to the non-destructive tests of combining structure, especially relates to a kind of bolt sleeve device realizing combining structure shear connector stiffness variation.
Background technology
Steel-concrete combined structure is as the rational form of structure of one, with its component with the anti-seismic performance that structural-load-carrying capacity is high, rigidity is large, sectional dimension is little and good, and there is many outstanding advantages such as significant technical economic benefit and social benefit, become the important feature form in China's civil engineering in this century gradually.
Shear connection ensures that steel and steel concrete form overall and important means that is stressed and compatible deformation jointly, and to study one of basic problem that steel-concrete combined structure must research and solve be exactly Shear connection problem.
Shear connector is the key of the medium-sized girder steel of combining structure and the collaborative work of concrete slab energy.The performance degradation of connector and the interface damage that causes thereof are by the service behaviour of extreme influence combining structure.If can identify the damage of connector in advance, then can avoid damaging by connector the structural deterioration brought.
The degraded performance of research connector, need to simulate the damage of connector in laboratory conditions, traditional method carries out static loading to compound beam, causes connector damage to a certain degree, recycles existing damage identification technique and identify.
Utilize the method for static loading to make the connector of combining structure produce damage, often need large-scale charger.Because combining structure has good ductility, the position destroyed at first under action of static load might not appear at connector, and the stressed complexity of combining structure under action of static load, carries out control inaccuracy to the degree of injury of connector.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, and provides that a kind of structure is simple, the bolt sleeve device realizing combining structure shear connector stiffness variation of low cost of manufacture.
The utility model solves the technical scheme that its technical problem adopts, a kind of bolt sleeve device realizing combining structure shear connector stiffness variation, comprise bolt and steel bushing, be provided with the screw thread suitable with the screw thread of bolt in described steel bushing, one end of described steel bushing is connected with sleeve enlarged footing.
Further, the preferred steel bushing of described sleeve.
Further, one end of described steel bushing and the affixed mode of sleeve enlarged footing are for welding.
Further, described sleeve enlarged footing shape of cross section be polygon.
Further, described sleeve enlarged footing the preferred hexagon of shape of cross section.
Compared with prior art, the utility model structure is simple, low cost of manufacture; Easy to use, the method of connector damage is manufactured by changing traditional static loading that utilizes, the finite stiffness being realized connector by simple effective method is connected, by the degree of tightness of adjusting bolt, make the never any shear resistance of structure change to shear stiffness maximum, thus realize the connection of its finite stiffness; Control accurately to damage position and degree of injury; Be conducive to the development of connector damage performance research, save the scientific research cost of researcher and reduce equipment requirement.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described further.
With reference to accompanying drawing 1a-1c, the present embodiment comprises bolt 1 and steel bushing 2, is provided with the screw thread 5 suitable with the screw thread 4 of bolt 1 in steel bushing 2, and one end of steel bushing 2 is connected with sleeve enlarged footing 3, prevents sleeve 2 from extracting from concrete slab 6.
One end of steel bushing 2 and the affixed mode of sleeve enlarged footing 3 are for welding.
Sleeve enlarged footing 3 shape of cross section be hexagon.
With reference to Fig. 2, be embedded in by sleeve 2 in concrete slab 6, have the circular hole suitable with bolt in i section steel beam 7 top flange corresponding below the location point embedding to sleeve 2, bolt 1, through the circular hole on girder steel 7, links together with sleeve 2; The welded sleeve enlarged footing 3 above of sleeve 2, thus prevent sleeve 2 from extracting from concrete slab 6.
With reference to Fig. 3, bolt sleeve device is lined up on i section steel beam 7 by certain spacing, make the diameter of bolt 1 identical with the shear connector diameter needing to simulate simultaneously, just can simulate the connection function of Welded-Stud Conectors in compound beam in laboratory conditions; Adopt spanner loose bolts 1, the length of adjustment bolt 1 inside sleeve 2, the degree of injury of simulation Welded-Stud Conectors.
Adopt the socket cap peg for combining structure shear connections that bolt sleeve unit simulation is traditional, when carrying out non-destructive tests test, bolt spanner can be unclamped a part, the contiguity of girder steel and concrete slab is reduced.The criterion of degree of injury can be used as simultaneously by the length measuring bolt looseness, realize the accurate control of simulation degree of injury.Meanwhile, the optional position that this device can be implemented in compound beam manufactures damage, achieves the simulation to connector damage position and degree of injury easily.
Meanwhile, in engineering, this class formation realizes the finite stiffness connection of connector, and its process is the degree of tightness by adjusting bolt, makes the never any shear resistance of structure change to shear stiffness maximum, thus realizes the connection of its finite stiffness.
