Description
Technical field
The present invention relates to field of bridge construction, and in particular to a kind of shear connector.
Background technique
Steel-concrete combined structure is that one kind is formed steel construction and concrete structure integrally altogether by shear connector
With the structure type of work, shear connector is the key that steel-concrete combined structure stress performance.This kind of structure type can
The mechanical property of steel and concrete material is given full play to, high, rigidity is greatly, self weight is small, stability is good with good bearing capacity
And the advantages that easy for construction, in the engineering fields extensive application such as bridge, building structure, piping lane.
With the development of engineering technology, requirement of the people to construction technology and construction quality is higher and higher, fabricated construction
The application of technology is further extensive.The construction of Standard formula can be achieved component and all complete in factory, can be improved component quality,
Construction material dosage is reduced, for building energy conservation important in inhibiting.Fabricated construction can greatly reduce site operation workload
And the time, stringent and site operation bad environments engineering important roles are required for the construction period.
The problem of how shear connector is set is faced in the fabricated construction of the mixed composite structure of steel-.At present using the most
Extensive Welded-Stud Conectors need multi-point to coordinate, and reserving point in precast slab can be since concrete be in hardening process
In contraction and change in location occurs, be unable to complete in installation process multi-point matching.Perforated steel plate connector is due to along beam
It is longitudinally continuous and runs through, longitudinal direction can not be reserved in precast slab through seam, and cannot achieve perforated steel plate connector and mix
Effective connection of solidifying soil prefabricated board.Concrete prefabricated board reserves large hole in separate type peg group's connection method existing at present
Hole, longitudinal reinforcement and transverse steel between reserving hole are all truncated, and seriously affect the globality of concrete slab, and peg group with
Power transmission is only carried out by rear pouring concrete between precast slab, Welded-Stud Conectors be unable to give full play effect by steel construction and
Concrete structure is connected to become entirety.
The prefabricated construction of steel-concrete combined structure needs to solve the problems, such as three aspects of connector.First, prefabricated mixed
How reserved hole location in concrete board is accurately docked with the Welded-Stud Conectors on steel construction.Second, how to reduce prefabricated mixed
Concrete board reserving hole reduces its influence to precast slab globality.How third gives full play to shear connector
Effect, is connected to become entirety for steel construction and concrete structure.
Patent CN201120487335 disclose it is a kind of in bridge construction fasten concrete shear key, if including by
The shear key ontology that shear key unit interconnected is constituted is done, the shear key unit includes support plate, the support plate
Both ends are provided with mounting plate, and several groups through-hole is provided on the mounting plate, is provided with support column between every group of through-hole.
Though the patent is using the entirety being interconnected to constitute using shear key unit, since its supporting plate structure is more multiple
It is miscellaneous, cause manufacturing process equally complex；Though being caused between its each shear key using its shear key unit set-up mode simultaneously
Entirety is so formed, but is affected to concrete globality.
Now need a kind of reserved hole location in precast slab that can carry out with the Welded-Stud Conectors on steel construction accurate
Docking；Concrete slab preformed hole is smaller；Steel construction and concrete structure are connected to become to whole shear connector.
Summary of the invention
The present invention is docked precisely to solve the reserved hole location of concrete slab in the prior art with Welded-Stud Conectors on steel construction
The problem of degree reduces the influence to precast slab globality, gives full play to the effect of shear connector, provides one kind and cuts
Power connector, concrete slab globality is high, and preformed hole is smaller, is easy to accurately dock, solves the above problem.
The present invention provides a kind of shear connector, including pin rod iron, pin rod iron mounting plate and perforated steel plate, pin
Installation through-hole is provided on rod iron mounting plate, pin rod iron is set in installation through-hole, and pin steel plate mounting plate is vertically installed in
