Description
Technical field
The invention belongs to steel-concrete composite beam connector technical field, relate in particular to a kind of novel stirrup shear connector and prepare mounting method.
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 the peg connector exists: the peg connector belongs to flexible connecting member, and larger distortion can be arranged, and 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 the 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, and 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 the open pore steel plate connector, be exactly typically FBL connector and Twin-FBL connector, brittle fracture easily appears, 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, the bent-up bar section is unfavorable for the layout of reinforcement in concrete.
Summary of the invention
The purpose of the embodiment of the present invention is to provide a kind of novel stirrup shear connector and prepares mounting method, 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 the bent-up bar connector is high to construction requirement.
The embodiment of the present invention 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 the stirrup inboard, and stirrup is arranged on the top flange of girder steel, and template-setup is on the top of end plate, and the stirrup shear connector is arranged on the centre position of template, and transverse reinforcement is arranged on template, the setting of staggering of transverse reinforcement and stirrup.
Further, the stirrup cross section is set to rectangle.
Further, longitudinal reinforcement is placed on the stirrup inboard by colligation.
Further, stirrup is arranged on the top flange of girder steel by welding.
Further, the stirrup shear connector is arranged on the centre position of template by end plate.
Further, transverse reinforcement and the stirrup setting of staggering.
Another purpose of the embodiment of the present invention is to provide a kind of mounting method for preparing of novel stirrup shear connector, and the mounting method for preparing of this novel stirrup shear connector comprises the following steps:
Make girder steel and stirrup welded unit, longitudinal reinforcement is placed on inboard four jiaos of stirrup and completes colligation;
Structure hoisting;
The assembling reinforcement of floor plate support template;
Concreting;
The normal maintenance of concrete form removal again.
Further, the diameter of the spacing of stirrup and diameter and longitudinal reinforcement and spacing are all determined according to the actual conditions of engineering.
Further, the assembling reinforcement of floor plate support template is the layer cloth muscle, has between two-layer reinforcing bar and supports to guarantee maintaining distance between two-layer reinforcing bar.
Novel stirrup shear connector provided by the invention and prepare mounting method, reinforcing cage and the girder steel top flange of by longitudinal reinforcement and stirrup colligation, getting up weld, then with concrete slab in laterally, the longitudinal reinforcement colligation gets up, and forms an integral body;
The present invention has the following advantages:
1. outer load is done the used time, and the lateral deformation that stirrup has limited concrete slab is set, and effectively improves shear strength and the rigidity of girder steel-concrete combined component;
2. by concreting, concrete and girder steel are realized vertical 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, realized the cooperative bearing of concrete and girder steel, simple structure, convenient construction;
4. the setting of stirrup, limited lateral deformation, is beneficial to the distortion of controlling whole concrete and girder steel element, limited and 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. on original basis, transformed, it is very general that longitudinal reinforcement and stirrup are used in concrete and girder steel engineering, is easy to obtain, the convenient making.
