Internal opposite side, and bend inwards, it is for cement mortar in groove in cast-in-place concrete, prefabricated panel seam.Above-mentioned connection
Wet type connection is fallen within, is come into operation there is presently no dry type connection.
Under the background that China greatly develops building industrialization, the requirement to construction quality, production efficiency and site environment
More and more higher, the dry type connection of precast shear wall becomes particularly important.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of precast shear wall dry type and hung down
The construction method of straight connecting node, comprises the following steps：
1）Precast shear wall is manufactured, includes tongue and groove, hair fastener type connector and the groove of end face, tongue and groove is carried out at dabbing
Reason, using modular mode in factory's manufacturer's standard precast shear wall module；
2）Standard precast shear wall module is hoisted to installation site, the tongue and groove of contiguous prefabricated shear wall connects, and hair fastener
Formula connector is mutually corresponded to；
3）Bolt is penetrated in the bolt hole of relative hair fastener type connector by the groove of both sides；
4）Bolt is tightened by the operating space of groove；
5）Groove is filled and led up using cement mortar.
Specifically, the linkage interface of the precast shear wall is provided with tongue and groove, and the tongue and groove is handled by dabbing, and its is close
The position of alien invasion is embedded with hair fastener type connector in precast shear wall；The hair fastener type connector includes the anchor being welded to each other
Expose the end face of tongue and groove on the outside of plate and dowel, the anchor slab, the dowel is anchored in the precast shear wall on the inside of anchor slab, institute
The center for stating anchor slab is provided with the precast shear wall on the inside of bolt hole, the bolt hole and is provided with groove；The linkage interface both sides
Hair fastener type connector symmetrically, and bolt is installed in a pair of bolts hole, the two ends of the bolt are located in groove.
Preferably, in order that dowel uniform stressed, improves the stability of anchoring, the dowel is symmetrically set along bolt hole
Four put, the angle of the dowel and anchor slab is 45 °.
Preferably, in order that the shear resistance of node is balanced with tensile capacity, the free end of the dowel is away from described
Bolt hole.The two ends of dowel are respectively to be welded in the fixing end of anchor slab and the free end away from anchor slab.
The thickness of the anchor slab is preferably 10mm.
In order to facilitate the arrangement of hair fastener type fixture, the diameter of the dowel and prefabricated shearing when the prefabricated shearing of manufacture is strong
The diameter of distribution bar is identical within the walls.
Beneficial effect：The present invention realizes the connection method of dry type, ring few with situ wet operation substantially at node
Border pollution is small, using factory prefabricated component, with easy construction, production efficiency height, short construction period, use of labor less,
The advantages of quality is easily controlled, meets building industrialization, the requirement of housing industrialization.Moreover, bolt connection hair fastener type connector
The globality of junction can effectively be strengthened, with higher bearing capacity.Due to whole hair fastener type connector be embedded in it is prefabricated
In shear wall, even if exposed anchor slab is also concordant with tongue and groove end face, in transport with special guarantor need not be to it in installing
Shield, and move up and down the alignment for realizing bolt hole after tongue and groove can be close in installation process, compared to existing exposed or
Breech-loading connector has the advantages that to be hardly damaged and is easily installed.The type of attachment can also be used for the level of precast shear wall
Connection.
