Abstract
A flexible stud shear connecting component for a steel and concrete composite structure aims to effectively optimize the stud arrangement scheme, and greatly facilitates the design and construction of the steel and concrete composite structure. The flexible stud shear connecting component comprises a steel component (10), a concrete component (20) and a stud (30) which is welded and fixed on the steel component (10) and is embedded in the concrete component (20), wherein a flexible rubber sleeve (40) is externally sleeved and arranged at the root part of the stud (30).
Description
Technical field
The utility model belongs to technical field of structural engineering, particularly a kind of flexibility weldering nail shearing connecting elements that is used for steel and concrete combined structure.
Background technology
In steel and the concrete combined structure, steel member and concrete component adopt common weldering nail connector to link to each other usually, promptly after the weldering of laying welding with it on the steel member is followed closely, and concrete perfusion on the steel member again.Under effects such as permanent mobile load, concrete shrinkage and temperature, when the weldering of several kinds of very limited diameters of on adopting design specifications, stipulating nail carries out layout design, the stressed mutual restriction of weldering nail shear stiffness, shear-carrying capacity and weldering nail and inharmonious usually appears.As weld nail and arrange overstockedly, possibly cause tensile stress bigger in the concrete, arranged like the weldering nail rare, then the bonding surface shear strength a little less than, weld that nail itself is stressed more also possibly to be caused self fatigue failure even directly cut off.Adopting the diversified joint construction of rigidity, to optimize weldering nail arrangement, is the technical barrier that the present technique field is not resolved for a long time.
The utility model content
The utility model technical problem to be solved provides a kind of flexibility weldering nail shearing connecting elements that is used for steel and concrete combined structure, can optimize weldering nail arrangement effectively, greatly facilitates the design and construction of steel and concrete combined structure.
It is following that the utility model solves the technical scheme that its technical problem adopted:
A kind of flexibility weldering nail shearing connecting elements that is used for steel and concrete combined structure of the utility model; Comprise steel member, concrete component; And be weldingly fixed on the steel member and imbed the weldering nail in the concrete component, it is characterized in that: the root overcoat of said weldering nail is provided with flexible rubber lagging.
The beneficial effect of the utility model is, allows the slippage that takes place between concrete component and the steel member to a certain degree, reduced the relative shear stiffness of steel member and concrete component bonding surface, guaranteed reliable shear strength; Effectively reduced the concrete pulling stress that causes by concrete shrinkage, variations in temperature in steel and the concrete combined structure; Effectively increased the pre-applied force effect of prestressed concrete bridge panel in steel and the concrete combined structure; The improvement that is used in compound beam tensile region concrete slab stress performance is arranged; Effectively reduced the suffered shearing of unit area weldering nail self, the possibility that has reduced weldering nail fatigue failure even directly cut off has significantly reduced the quantity of weldering nail on the unit area; Can obtain the diversified flexible weldering nail shear connector of rigidity, optimize weldering nail arrangement; Easy construction does not influence the duration.
Description of drawings
This manual comprises following three width of cloth accompanying drawings:
Fig. 1 is a kind of sectional view that is used for the flexibility weldering nail shearing connecting elements of steel and concrete combined structure of the utility model.
Fig. 2 is the local enlarged diagram of A among Fig. 1;
Fig. 3 is a kind of flexibility weldering nail shearing connecting elements weldering nail of steel and concrete combined structure and connected mode sketch map of flexible rubber lagging of being used for of the utility model;
Component shown in the figure, toponym and pairing mark: steel member 10, concrete component 20, weldering nail 30, flexible rubber lagging 40, longitudinal opening 41, fixture 42.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
With reference to Fig. 1; A kind of flexibility weldering nail shearing connecting elements that is used for steel and concrete combined structure; Comprise steel member 10, concrete component 20, and be weldingly fixed on the steel member structure 10 and imbed the welderings nail 30 in the concrete component 20 that the root overcoat of said weldering nail 30 is provided with flexible rubber lagging 40.In the construction; To weld nail 30 and be welded on the steel member, at weldering nail 30 roots flexible rubber lagging 40 will be installed then, on steel member 10, build concrete component 20 again; After treating that concrete component 20 reaches design strength, can transmit the internal force between steel member and the concrete component through this shear connector.With same specification but do not compare with the weldering nail of flexible rubber lagging, this connector shear stiffness is less, and shear-carrying capacity is identical, is a kind of flexible weldering nail shearing connecting elements.Allow the slippage that takes place between concrete component and the steel member to a certain degree, reduced the relative shear stiffness of steel member and concrete component bonding surface, guaranteed reliable shear strength; Effectively reduced the concrete pulling stress that causes by concrete shrinkage, variations in temperature in steel and the concrete combined structure; Effectively increase the pre-applied force effect of prestressed concrete bridge panel in steel and the concrete combined structure, and the improvement that is used in compound beam tensile region concrete slab stress performance has been arranged, and effectively reduced the suffered shearing of unit area weldering nail self; The possibility that has reduced weldering nail fatigue failure even directly cut off; Significantly reduce the quantity of weldering nail on the unit area, therefore can obtain the diversified flexible weldering nail shear connector of rigidity, optimized weldering nail arrangement; And easy construction, do not influence the duration.
Weldering nail 30 specifications can adopt any one specification of regulation in " electric arc stud welding is with socket cap weldering nail " (GB/T 10433-2002).Flexible rubber lagging 40 adopts the bridge pad of good springiness, good endurance to process with rubber, and its hardness, length and thickness can be done any adjustment according to requirement of engineering.Since the variation of weldering nail 30 specifications, flexible rubber lagging 40 types, the flexibility weldering nail shear connector that therefore can obtain to have various rigidity.
With reference to Fig. 2 and Fig. 3, be convenient construction, said flexible rubber lagging 40 has longitudinal opening 41, can be processed into circular tube in advance, it is cut off along short transverse form longitudinal opening 41 again, is inserted on weldering nail 30 roots again.Said flexible rubber lagging 40 is bonding with weldering nail 30, perhaps is fixedly connected with weldering nail 30 through fixture 42, and fixture 42 can adopt iron to prick silk, nylon cable tie or anchor clamps etc. usually.Flexible rubber lagging 40.
The above the utility model that just explains through diagrams is used for some principles of the flexibility weldering nail shearing connecting elements of steel and concrete combined structure; Be not be to the utility model be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
