Description
Technical field
The utility model belongs to steel-concrete composite beam connector technical field, relates in particular to a kind of spiral stirrup shear connector.
Background technology
Steel-concrete composite beam is, by shear connector, girder steel and concrete slab are linked to be to integral body and cooperative bending resistance component.Shear connector is the critical component of steel-concrete composite beam, and its Main Function has two: the one, be used for bearing and transmitting the longitudinal shear between girder steel and concrete slab; The 2nd, be used for resisting the effect that starts between concrete slab and girder steel.In general, shear connector can be divided into rigid connector and the large class of flexible connecting member two, and concrete can be divided into following four kinds: peg connector, bent-up bar connector, shaped steel shear connector, open pore steel plate connector.
The shortcoming that peg connector exists: peg connector belongs to flexible connecting member, can have larger distortion, along with the progress of distortion, bearing capacity there will be very large reduction.In addition, the head of a nail on peg has and certain anti-ly starts effect (girder steel and concrete slab produce gap between inconsistent causing of distortion under power effect), but slabbing action, and the fracture propagation in head of a nail surrounding concrete is very fast, the outstanding area of the head of a nail is less in addition, and it is limited in one's ability that antagonism is lifted.
The shortcoming of shaped steel shear connector: volume is larger, its steel quantity consumption is large, and large welding capacity makes the larger shortcomings such as residual strain by welding of generation on steel plate.
The shortcoming of open pore steel plate connector: in open pore steel plate connector, be exactly typically FBL connector and Twin-FBL connector, easily there is brittle fracture, and perforated panel connector stress of living in and concreting direction have larger negative effect to its shear stiffness, operational phase shear strength, and steel using amount is very large, moreover, the existence of steel plate also separates concrete some separating, directly affect the globality of concrete slab, make the well collaborative work of concrete and girder steel, finally affect the bearing capacity of combining structure.
The shortcoming of bent-up bar connector: the one-way of Transfer of Shear, can only transmit the shearing of fixed-direction, can not transmit the shearing of alternating direction.Therefore, the setting party of bent-up bar connector is to very tight, to construction require highly, in addition, bent-up bar section is unfavorable for the layout of reinforcement in concrete.
Existing peg connector non-deformability is poor, shaped steel shear connector steel quantity consumption is large and have that welding residual stress, open pore steel plate connector are prone to brittle fracture, bent-up bar connector is high to construction requirement.
Utility model content
The object of the utility model embodiment is to provide a kind of spiral stirrup shear connector, is intended to solve that existing peg connector non-deformability is poor, shaped steel shear connector steel quantity consumption large and exist welding residual stress, open pore steel plate connector to be prone to brittle fracture, problem that bent-up bar connector is high to construction requirement.
The utility model embodiment is achieved in that a kind of spiral stirrup shear connector, and this spiral stirrup shear connector comprises: spiral stirrup connector, girder steel, template, end plate, longitudinal reinforcement, transverse reinforcement;
Spiral stirrup connector is arranged on the top flange of girder steel, and template-setup is on the top of end plate, and spiral stirrup connector is arranged on the centre position of template, and transverse reinforcement is arranged in template, and longitudinal reinforcement arranges between transverse reinforcement.
Further, spiral stirrup connector is arranged on the top flange of girder steel by welding.
Further, spiral stirrup connector is arranged on the centre position of template by colligation.
Further, longitudinal reinforcement, transverse reinforcement and spiral stirrup connector link together by colligation.
The spiral stirrup shear connector that the utility model provides, by spiral stirrup shear connector being welded on to the top flange of girder steel, again with concrete slab in laterally, longitudinal reinforcement colligation gets up, the colligation of the longitudinal reinforcement especially closing on, has improved the overall performance of steel-concrete composite beam; The utlity model has following advantage:
1. spiral stirrup is set, has limited the lateral deformation of concrete slab, improved shear strength and the rigidity of girder steel-concrete combined component, limited and started distortion;
2. by concreting, concrete and girder steel have been realized longitudinal and vertical shearing resistance by this stirrup shear connector;
3. spiral stirrup and longitudinal reinforcement are set auxiliary, have realized the cooperative bearing of concrete and girder steel, young simple, the convenient construction of dog, has reduced cost of labor, has improved throughput rate and duration;
4. spiral stirrup is set, has limited lateral deformation, be conducive to control the distortion of girder steel-concrete combined component, the plasticity that effectively increases girder steel-concrete combined component is deformable ability, has improved stability and reliability.
