Description
Technical field
The utility model relates to construction steel structure fields, are a kind of inverted plug type shear connector structures more specifically.
Background technique
All kinds of cantilever rod structures (such as single-pipe tower, single-column overpass etc.) and other various needs are two-way by curved steel knot
Structure column, frequently with large-sized square steel tube or round steel pipe, suspension column must just be able to satisfy structure stress and want column section with basic just connect
It asks.Prestressed bolt connection suspension column and basis can reach and preferably just connect effect, and anti-fatigue performance is good, and opposite embedded column base subtracts
The small mutation of stiffness and strength, avoids the repetition configuration of reinforcing bar, and utilization is more and more extensive.But it is sheared in extra reception
When, due to the surface layer steel plate of basic surface layer setting, there are problems that shear key can not be arranged.
Utility model content
Since the prior art is there is above-mentioned technical problem, the application proposes a kind of inverted plug type shear connector structure, purpose
It is to solve the difficult point of shear key setting of the steel pipe column heel foundation with surface layer steel plate in existing engineering.
To reach above-mentioned technical problem, the application uses following technological means:
A kind of inverted plug type shear connector structure, comprising: cushion cap, the cushion cap upper surface are equipped with a shearing resistance keyhole；Base surface steel
Plate and column root-plate, the upper surface for being set to the cushion cap from top to bottom, and the base surface steel plate and the suspension column
Bottom plate is fixed on the cushion cap by high-strength bolt, is offered on the base surface steel plate and the column root-plate and is resisted with described
Cut the corresponding perforation of keyhole；Shear key is embedded in the shearing resistance keyhole, and passes through the base surface steel plate and suspension column bottom
Plate, the buried depth of the shear key is twice of shear key cross section numerical value, and the shear key exposes the height of the surface layer
It spends consistent with buried depth；Steel pipe column is set on the column root-plate, and expansive concrete is filled in the steel pipe column.
It is preferred that the exterior bottom of the steel pipe column is equipped with outside column foot of putting more energy into, put more energy into outside the column foot and the suspension column
Bottom plate connection.
It is preferred that the medial surface of the steel pipe column is equipped in column foot of putting more energy into, put more energy into the column foot and the suspension column bottom
Plate connection.
Inverted plug type shear connector structure due to using above-mentioned technological means, the application can not cancel basic surface layer steel plate
Shear key can be successfully arranged in setting on suspension column.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
It is shown in Figure 1, it is the structural schematic diagram of the utility model.Inverted plug type shear connector structure in the present embodiment, comprising:
The structures such as cushion cap 1, base surface steel plate 2, column root-plate 3, steel pipe column 4, shear key 5.
1 upper surface of cushion cap is equipped with a shearing resistance keyhole 11.Base surface steel plate 2 and column root-plate 3 setting from top to bottom
Be placed in the upper surface of the cushion cap 1, and the base surface steel plate 2 and the column root-plate 3 be fixed on by foundation bolt 6 it is described
On cushion cap 1.Under the future for not influencing base surface steel plate purposes, opened up on the base surface steel plate 2 and the column root-plate 3
There is perforation corresponding with the shearing resistance keyhole 11.When pouring cushion cap, the foundation bolt, shear key and base surface steel plate one
And buried foundation.
Shear key 5 is embedded in the shearing resistance keyhole 11, and passes through the base surface steel plate 2 and column root-plate 3.It is assumed that mixed
Solidifying soil stress strain is linear relationship, and the moment of flexure EQUILIBRIUM CALCULATION FOR PROCESS of the bearing capacity of concrete-filled of shearing and distribution is born according to shear key 5,
The shear key 5 buried depth in cushion cap is twice of the 5 cross section numerical value of shear key, and the shear key 5 exposes the face
The height of layer is consistent with buried depth.
Steel pipe column 4 is set on the column root-plate 3, fills expansive concrete 7 in the steel pipe column 4.Compensation is shunk
Concrete seven level-one higher than the concrete grade for pouring cushion cap, and it is aided with outer concrete vibrator vibration compacting.Shear key passes through
Expansive concrete is closely connect with the steel pipe column, thus Transfer of Shear；Coagulation is shunk in filling compensation in the steel pipe column
Soil also reduces stress mutation caused by cushion cap to the steel pipe column material, changes of section.
The exterior bottom of the steel pipe column 4 is equipped with column adding rib 41, the column adding rib 41 and the column root-plate 3
And the column outer wall welding.The medial surface of the steel pipe column 4 is equipped with ribbed stiffener 42 in column, and the effect of ribbed stiffener 42 is to reduce stress
It is mutated, ribbed stiffener and the column wall weld in the column.
It is connected as it appears from the above, the application is successfully solved using prestressed bolt, fixing steel plate is set in basic surface layer
Or the problem of secondary grout layer can not be set, cause shear key that can not be arranged after junction steel plate.
Embodiments described above is merely to illustrate the utility model rather than limitation the scope of the utility model.This
The equivalent changes and modifications that field technical staff does the utility model all should belong to the utility model the attached claims
The covering scope of book.
