Description

A kind of novel stirrup shear connector
Technical field
The utility model belongs to steel-concrete composite beam connector technical field, relates in particular to a kind of novel stirrup shear connector.
Background technology
Steel-concrete composite beam is, by shear connector, girder steel and concrete slab are linked to be to entirety 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 certain anti-effect (under power effect girder steel and produce gap between concrete slab inconsistent causing of distortion) that starts, but slabbing action, 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 shortcomings such as the residual strain by welding that on steel plate, generation is larger.
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.
Utility model content
The object of the utility model embodiment is to provide a kind of novel 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 novel stirrup shear connector, and this novel stirrup shear connector comprises: stirrup shear connector, stirrup, longitudinal reinforcement, girder steel, template, end plate, transverse reinforcement;
Longitudinal reinforcement is placed on stirrup inner side, and stirrup is arranged on the top flange of girder steel, and template-setup is on the top of end plate, and stirrup shear connector is arranged on the centre position of template, and transverse reinforcement is arranged in template, the setting of staggering of transverse reinforcement and stirrup.
Further, stirrup cross section is set to rectangle.
Further, longitudinal reinforcement is placed on stirrup inner side by colligation.
Further, stirrup is arranged on the top flange of girder steel by welding.
Further, stirrup shear connector is arranged on the centre position of template by colligation.
Further, transverse reinforcement and the stirrup setting of staggering.
The utlity model has following advantage:
1. outer load is done the used time, stirrup is set has limited the lateral deformation of concrete slab, effectively improves shear strength and the rigidity of girder steel-concrete combined component;
2. by concreting, concrete and girder steel are realized longitudinal and vertical shearing resistance by this stirrup shear connector, and concrete and connector interweave mutually, have improved overall performance and vertical shear resistance;
3. longitudinal reinforcement and stirrup setting, has realized the cooperative bearing of concrete and girder steel, simple structure, convenient construction;
4. the setting of stirrup, has limited lateral deformation, is beneficial to the distortion of controlling whole concrete and girder steel element, has limited and has started distortion;
5. the plasticity that has effectively increased concrete and girder steel is deformable ability, has improved stability and the reliability of concrete and girder steel;
6. transform on original basis, it is very general that longitudinal reinforcement and stirrup are used in concrete and girder steel engineering, is easy to obtain, convenient making.
