The shear connector used in structure has the advantages that simple for production, joint efficiency is higher, durability is more preferable.
The object of the invention can be achieved through the following technical solutions：A kind of shearing used in steel-concrete combined structure
Connector, including a steel plate, it is characterised in that perforate is set on the steel plate, and the opening hole wall edge sets chamfering, the steel
Plate is connected with steel construction by twin fillet wolt, and through reinforcing bar in hole, by pouring into a mould the concrete steel plate bag
It is rolled in concrete structure, so that concrete tenon is formed in the perforate of the steel plate, steel construction is tight with concrete structure
It is close to combine.
Further, reinforcing bar is run through in the steel plate perforate in providing holes.
Further, the steel plate perforate is single perforate or multiple perforates.
Further, the steel plate perforate is circular hole, elliptical aperture or slot.
Further, the steel plate perforate is equidistant or non-be equally spaced.
Further, the steel plate hole shape and size can be single specification or plurality of specifications.
Further, the unilateral side of the steel plate all or part perforate or both sides of the edge chamfering.
Further, the hole edge chamfering form of the perforate can be bevelling（Equilateral or inequilateral oblique angle）Or rounding
Angle.
Further, perforate side chamfer dimesion R or a scope be 0 ~ t/3, R be hole edge rounded corner when chamfer radius,
Bevelling size in thickness of slab direction when a is hole edge bevelling, t are open pore steel plate thickness of slab.
Compared with prior art, the present invention overcomes existing perforated plate connector hole edge concrete tenon stress to there is stress collection
The shortcomings that middle phenomenon；The concrete tenon shear resistent area at steel-concrete interface is increased after steel plate perforate hole edge chamfering, from
And improve the shear-carrying capacity and shear stiffness of connector；Concrete tenon is avoided due to stress collection after steel plate perforate hole edge chamfering
In caused premature harm cracking, improve the durability of connector and stress ductility；The invention need not increase connector
Structure size, verge of opening chamfering easy construction is easy, has the advantages that safe, economical, durable, construction is convenient.The present invention's
The technical issues of advantage is the perforated plate connector hole edge concrete stress concentration for overcoming existing form, to improving perforated panel
Concrete tenon cracking destruction has remarkable effect in the shear-carrying capacity and shear stiffness of connector, delay perforate；Perforated panel hole edge
Chamfer machining is simple and practicable, has the advantages that safe, economical.

Specific embodiment
The feature of the present invention is described in further detail by embodiment below in conjunction with attached drawing, in order to technology of the same trade
The understanding of personnel：
Such as Fig. 1 ~ 4, figure acceptance of the bid note is respectively：Through reinforcing bar 4, steel plate in shear connector 1, steel construction 2, concrete structure 3, hole
Perforate 11, hole edge chamfering 12.Chamfer radius when R is hole edge rounded corner, bevelling ruler in thickness of slab direction when a is hole edge bevelling
Very little, bevelling size in plate plane when b is hole edge bevelling, t is open pore steel plate thickness of slab.
Embodiment：
The shear connector used in a kind of steel-concrete combined structure, structure is as shown in Figure 1, and the shear connector 1 is by one
Block steel plate sets single or multiple steel plate perforates 11 to form, it is characterised in that at the hole wall edge of steel plate perforate 11 hole edge is set to fall
Angle 12.The shape of perforate 11 can be circular hole, elliptical aperture or slot；Perforate 11 on steel plate can be equidistantly arrangement or
Non- equidistant arrangement.Hole edge chamfering 12 can be bevelling or rounded corner, chamfer dimesion（R or a）Scope is 0 ~ t/3.In addition, steel
It can set through reinforcing bar, can not also be set through reinforcing bar in plate perforate 11.
The service condition of the present invention is as shown in Figure 2.Shear connector 1 is connected with steel construction 2 by twin fillet wolt, according to
Stress and construction needed to decide whether in providing holes through reinforcing bar 4, then by pouring into a mould the perforate of concrete hole edge chamfering
Plate connector 1 is wrapped in concrete structure 3, and the steel plate after concrete hardenings in the perforated plate connector 1 of hole edge chamfering is waited to open
Concrete tenon is formed in hole 11, steel construction and concrete structure are combined closely.
The perforated plate connector of hole edge chamfering of the present invention is applied in steel-concrete combined structure, can be effectively by steel
Structure is connected with concrete structure, and operation principle is as follows：First, the perforated plate connector 1 and steel construction of hole edge chamfering
Connected by twin fillet wolt, the weld seam can transfer steel construction along open pore steel plate length direction cutting parallel to bead direction
Power, while the horizontal force perpendicular to bead direction can be undertaken, it ensure that steel construction 2 and the perforated panel of hole edge chamfering connect by weld seam
Effective connection of fitting 1.Secondly, the perforated plate connector 1 of hole edge chamfering three aspects main with the connection of concrete structure 3 are real
It is existing：First, the concrete of cast can be undertaken by forming concrete tenon after the hardening of steel plate perforate 11 in open pore steel plate plane
Shearing between steel construction and concrete structure；Second, concrete contacts pressure-bearing with open pore steel plate and can transfer perpendicular to perforate steel
The horizontal force in plate direction；3rd, in providing holes after reinforcing bar 4, cutting in 1 plane of open pore steel plate can be undertaken through reinforcing bar 4
Power simultaneously forms constraint to the concrete of 11 both sides of steel plate perforate, enhances connection.There is provided hole edges at the edge of steel plate perforate 11 to fall
Behind angle 12, increase the concrete tenon shear resistent area at steel-concrete interface, so as to improve the shear-carrying capacity of connector and
Shear stiffness；Concrete tenon premature harm caused by stress concentration is avoided to crack after steel plate perforate hole edge chamfering, is improved
The durability of connector and stress ductility.It should be noted that hole edge chamfer dimesion（R or a）No more than open pore steel plate plate
Thick 1/3rd（t/3）, the hole wall plane width otherwise between verge of opening chamfering is narrow, the shearing in open pore steel plate plane
New region of stress concentration is easily formed under effect, forms slabbing action to concrete tenon, shear-carrying capacity to connector and
Durability is unfavorable.
Therefore, when shear connector of the invention is applied to steel-concrete combined structure, joint efficiency is opened than traditional
Orifice plate connector higher, in the case where bore size is identical, the perforated plate connector of hole edge chamfering has higher shearing strength
And shear stiffness, it avoids concrete tenon premature harm caused by hole-edge stress concentration in hole and cracks, improve connector
Durability and stress ductility, have the advantages that it is safe, economical, durable, construction it is convenient.
