The utility model discloses interval arrangement channel-section steel connecting piece and the curved steel bar connecting piece on the girder steel for curved steel bar connecting piece shears with channel-section steel connecting piece jointly, guarantees girder steel and concrete floor collaborative work, reaches the purpose that improves the structure bearing capacity.
Description
Technical field
The utility model relates to civil engineering work technical field of structures, is specifically related to a kind of mixing shear connector.
Background technology
Peg is flexible connecting member, and stressed do not have a directionality, and volume is little, and flexible arrangement is convenient but shear-carrying capacity is little, and bending rigidity is little, and pressure-bearing surface is little, and Root Stress concentration degree is large, and too much welding has produced too much residual stress.Although have good deformability, bearing capacity is lower.And need special-purpose welding machine and porcelain ring, construction technology is comparatively complicated.
The in the situation that of conditions permit, most of meeting adopts peg connector, and lower bearing capacity makes, in opposing shearing, can use a large amount of pegs.Although the supporting capacity of the actual bearer energy force rate current Chinese code of practice of peg the inside regulation is much bigger, the design formulas of shear capacity of studs is relatively conservative, thereby it is further on the high side to cause calculating needed peg quantity, and spacing is less than normal.Except being unfavorable for design structure, increased cost, also brought trouble also to follow-up construction simultaneously, affected the speed of engineering.
The inclined to one side rigidity of channel-section steel connector, in the situation that not possessing welding of peg equipment, the connector of channel-section steel is a kind of effective alternative, the easy construction of channel-section steel connector also has the stronger anti-ability of starting simultaneously.Although compared with general flexible connecting member, bearing capacity is higher, deformability is poor, and brittle fracture easily occurs during destruction.
Except the connector of above two kinds, the PBL connector rising again in recent years.That a kind of transverse reinforcement by concrete and perforated holes forms whole common opposing shearing, although it has fatigue behaviour to be better than peg, bearing capacity is high, the advantage such as the good and construction method of anti-fatigue performance is simple, but the discreteness of the ultimate bearing capacity of PBL connector, much larger than peg, is therefore not easy to simulate reliable design formulas, does not also have standard to make regulation to the size of PBL connector and supporting capacity both at home and abroad at present, therefore, inconvenience application.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of mixing shear connector that has rigid connector and flexible connecting member advantage concurrently is provided, this connector is interval arrangement of grooves steel fastener and bent-up bar connector on girder steel, make bent-up bar connector and the common shearing resistance of channel-section steel connector, guarantee girder steel and concrete floor collaborative work, reach the object that improves structural bearing capacity.
The technical solution adopted in the utility model is: a kind of mixing shear connector, comprise channel-section steel connector and bent-up bar connector, described channel-section steel connector and bent-up bar connector are arranged in floor, channel-section steel connector and bent-up bar connector alternate layout on girder steel, at beam-ends, described channel-section steel connector should be set, the web of channel-section steel connector is provided with preformed hole, and the reinforcing bar in described floor in reinforced mesh is through described preformed hole.
As preferably, described bent-up bar connector place sets up additional transverse steel bars, and fastening with bent-up bar connector.
Novel mixing shear connector of the present utility model is jointly to consist of the channel-section steel connector of inclined to one side rigidity and partially flexible bent-up bar connector.This novel mixing shear connector jointly being formed by rigid connector and flexible connecting member, both reduced the brittle behavior of simple rigid connector structure, increased the ductility of structure, strengthened the anti-fatigue performance of structure, overcome again the larger defect of distortion of simple flexible connecting member structure, make its more reasonable stress, performance is more superior.
When the utility model is arranged shear connector, channel-section steel connector and bent-up bar connector are answered alternate layout, and the suitable arrangement of grooves steel fastener of beam-ends, to utilize its stronger anti-ability of starting.Reinforcing bar in floor in reinforced mesh, when meeting with channel-section steel connector, passes the channel-section steel connector web of drilling, and both convenient construction, had strengthened again reinforcing bar and shear connector connection function.In order further to increase the connection function of reinforcing bar and shear connector, at bent-up bar connector, place sets up transverse reinforcement, and connects jail.Reinforced mesh in floor (containing the transverse reinforcement of setting up) is firmly connected with shear connector like this, also just means the adhesion stress having strengthened between shear connector and concrete, thereby has increased combined effect.
Shear connector in the utility model (containing channel-section steel connector and bent-up bar connector) is connected by weld seam with girder steel, only needs conventional machining and welding equipment, without need special welding equipment as peg connector.
Beneficial effect: the utility model, with respect to the rigid connector structure of traditional form, has reduced the brittle behavior of structure, has increased the ductility of structure, has strengthened the anti-fatigue performance of structure.
The utility model, with respect to the flexible connecting member structure of traditional form, has reduced the moderate finite deformation of combining structure, makes its more reasonable stress, and performance is more superior.
The utility model, with respect to the peg connector of traditional form, does not need special welding equipment, can reduce fielding welding workload, reduces fabrication and installation cost, accelerates the speed of application of engineering, reduces the total cost of engineering.
The anti-ability of starting of the utility model structure is strong.
Shear connector of the present utility model is drawn materials easily, and cost is low; Easy to connect, construction is fast; Adhesion stress is strong, and combined effect is good; There is good overall economic efficiency.
The utility model proposes the new approaches of stud connector design, expanded the range of application of combining structure, there is good social benefit and conversion prospect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model mixing shear connector.
The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of mixing shear connector, comprise channel-section steel connector 1 and bent-up bar connector 2, described channel-section steel connector 1 and bent-up bar connector 2 are arranged in floor, channel-section steel connector 1 and bent-up bar connector 2 alternate layout on girder steel 3, at beam-ends, described channel-section steel connector 1 should be set, the web of channel-section steel connector 1 is provided with preformed hole, and the longitudinal reinforcement 4 in described floor in reinforced mesh is through described preformed hole.
