Description
Technical field
The present invention relates to a kind of dowel embedded part, and in particular to a kind of bow formula dowel of assembly concrete superstructure plate face buries
Part, belongs to technical field of civil engineering.
Background technology
The assembly concrete superstructure that prefabricated components are formed is used, it is necessary to take connection measure to protect between each prefabricated components
Building cover structure rigidity is demonstrate,proved, makes its overall work.At present, frequently with plate face connection method mainly have two kinds, one kind is in component
After assembly between each component preset slot, reinforcing bar is targetedly arranged using direct perfusion pea gravel concreten or high-intensity earthquake fortification zone
And the method for pouring coincidence surface plate；Another kind is to arrange built-in fitting to edge in each prefabricated components length, and in component assembly rear cover
Plate is welded to connect.Though the problem of this two classes measure alleviates assembly concrete superstructure globality poor to a certain extent, superstructure
Flat in-plane stiffness is still relatively low, and under severe earthquake action, superstructure may occur in larger plane and deformity out of plane, causes building cover structure
Seismic Damage, be also easy to cause because of prefabricated components and its bearing dockingundocking, so as to cause structural system to be destroyed, it is difficult to ensure
Structure safety.
To sum up, existing superstructure plate face connection method superstructure under severe earthquake action may occur in larger plane and plane
Outer deformation causes because of prefabricated components and its bearing dockingundocking.
The content of the invention
To solve existing superstructure plate face connection method superstructure under severe earthquake action larger plane may occur for the present invention
Interior and deformity out of plane causes because of prefabricated components and the problem of its bearing dockingundocking, and then provides a kind of assembly concrete
The bow formula dowel embedded part of superstructure plate face.
The present invention adopts the technical scheme that to solve above-mentioned technical problem：
The bow formula dowel embedded part of the assembly concrete superstructure plate face of the present invention includes dowel 1-1, connection end plate 1-2, pin
Keypad 1-3 and pin key reinforcing bar 1-4, the dowel 1-1 is arched, is welded on connection end plate 1-2 and connects in the middle part of dowel 1-1
End plate 1-2 is located on the forearm of dowel 1-1, and pin key plate 1-3 is welded on the middle part of connection end plate 1-2 and the two is vertically arranged, and sells
Key reinforcing bar 1-4 is welded on the middle part of pin key plate 1-3 and pin key reinforcing bar 1-4 is vertically arranged with being connected end plate 1-2, dowel 1-1, pin key
Plate 1-3 and pin key reinforcing bar 1-4 is the bow formula dowel embedded part and 3 plate face of precast floor slab on the same side for connect end plate 1-2
After reinforcing bar is bound, cast forms precast floor slab, is connected between two neighboring precast floor slab by two connection end plate 1-2 welding
Connect.
Further, dowel 1-1 and pin key reinforcing bar 1-4 are in the same plane.
Further, it is vertically arranged between dowel 1-1 and pin key plate 1-3.
Further, the consistency of thickness of the width of connection end plate 1-2 and the width of pin key plate 1-3 with precast floor slab 3 is set
Put.
Further, it is welded as a whole between two neighboring connection end plate 1-2 by connecting reinforcing bar 2.
The present invention has the advantages that compared with prior art：
The bow formula dowel embedded part of the assembly concrete superstructure plate face of the present invention is embedded in precast floor slab, contiguous prefabricated building
Plate connects to form Assembled Building cover board by bending formula dowel embedded part and connection reinforcement welding, and the present invention effectively increases assembled and mixes
The globality peace in-plane stiffness of solidifying Tulou cover board, greatly reduces under geological process in the plane of assembly concrete building cover board
Deformation, improves Assembled Building Strap joint ultimate bearing capacity more than 50%, effectively alleviates welding temperature stress to assembled
The influence of building cover board joint behavior.
