Abstract
The utility model discloses a shear connector, which aims to effectively improve the shearing resistance of a steel-concrete combined structure. The shear connector comprises a steel component (10) and through holes (11) for the penetration of reinforced bars, wherein the steel component (10) is provided with 4 facades (10a, 10b, 10c and 10d), the two facades (10a and 10b) are perpendicular to the other two facades (10c and 10d), and the through holes (11) are uniformly formed on the facades (10a, 10b, 10c and 10d). The utility model has the benefits that the shearing resistance of the combined structure can be effectively improved, and the efficiency of the steel-concrete combined structure can be fully achieved; a steel structure and a reinforced concrete structure can be combined together more effectively; and compared with the traditional plate type shear connectors, the shear connector requires less combined reinforced bars for the same effect, thereby facilitating the construction cost reduction.
Description
Technical field
The utility model belongs to technical field of civil engineering, and characteristics relate to a kind of shear connector that is used to connect steel work, reinforced concrete structure.
Background technology
At the bridge shear connector is a kind of member that is used to connect steel work, reinforced concrete structure.At present, many countries have studied multiple shear connector device and have used in the combining structure beam, but different shear connectors all can have certain influence to the economy and the durability of bridge or building structure.
Existing shear connector all is to adopt traditional weldering to follow closely the shear connector in opened round hole on the rectangular steel plates of a formula shear connector or a direction basically, and traditional weldering nail formula shear connector is because the restriction of shear-carrying capacity is used less in longspan structure or in the composite beam bridge.Opening shear connector in the past all is that the steel plate of rectangle is welded on the steel work, because shear connector mainly bears shearing, the rectangular steel plates material uses bigger waste more, and can only consider the stressed of a direction, and is powerless for orthotropic plate.
The utility model content
But technical problem to be solved in the utility model provides a kind of shear connector of bidirectional stress, can improve the shear resistance of steel-concrete combined structure effectively.
The technical scheme that its technical problem that solves the utility model adopts is: shear connector of the present utility model, comprise steel components and the through hole that passes for reinforcing bar, it is characterized in that: described steel components has 4 facades, and wherein two facades are laid with through hole perpendicular to other two facades on each facade.。
The beneficial effects of the utility model are, can improve the shear resistance of combining structure effectively, give full play to the efficient of steel-concrete combined structure, especially can fully play the effect of shear connector bidirectional stress orthotropic plate and concrete combining structure; Can make that steel work and reinforced concrete structure are more effective to combine, thereby improve the binding ability of two kinds of materials; Shear connector self can play the effect of cage of reinforcement, can control concrete thickness between reinforcing bar and steel work accurately; Compare with traditional board-like shear connector, can use combination steel rib still less, and reach same effect, help reducing construction costs.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the stereogram of the utility model shear connector;
Fig. 2 is the user mode schematic diagram of the utility model shear connector.
Component, position and numbering among the figure: steel components 10, facade 10a, facade 10b, facade 10c, facade 10d, through hole 11, reinforced concrete structure 20, longitudinal reinforcement 21, transverse reinforcement 22, steel work 30.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, shear connector of the present utility model comprises steel components 10 and the through hole 11 that passes for reinforcing bar, described steel components 10 has 4 facade 10a, 10b, 10c, 10d, wherein two facade 10a, 10b are laid with through hole 11 perpendicular to other two facade 10a, 10b, 10c, 10d on each facade 10a, 10b, 10c, the 10d.。With reference to Fig. 2, reinforced concrete structure 20 and steel work 30 connect as one by shear connector, the lower end of shear connector and steel work 30 welding, longitudinal reinforcement 21 in the reinforced concrete structure 20, transverse reinforcement 22 pass the through hole 11 on the shear connector and weld with shear connector, longitudinal reinforcement 21 and transverse reinforcement 22 colligations, shear connector is cast among the reinforced concrete structure 20.Because longitudinal reinforcement 21, transverse reinforcement 22 pass same seat shear connector and welding with it, this shear connector is subjected to the effect of bidirectional stress, therefore can make steel work and reinforced concrete structure is more effective combines, and improve the shear resistance of steel-concrete combined structure, give full play to the efficient of combining structure.
With reference to Fig. 1, be convenient construction, described through hole 11 has the opening that communicates with the outside incline of place facade 10a, 10b, 10c, 10d.The quantity of through hole 11 can be determined according to the specific requirement of steel-concrete combined structure, usually respectively lay a through hole 11 on described facade 10a, 10b, 10c, the 10d, if have multilayer longitudinal reinforcement 21, transverse reinforcement 22 in the reinforced concrete structure 20, but the open hole 11 of then described facade 10a, 10b, 10c, the last longitudinal separation laying of 10d equal number.
Described steel components 10 can be welded by the steel plate of two square crossings, and with reference to Fig. 1, for saving rolled steel dosage, this two block plate is trapezoidal, its bottom surface and steel work 30 welding during use.For adapting to the needs of producing in batches and reducing production costs, described steel components 10 also can have been adopted cast steel member.
Some principles of the above the utility model shear connector that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
