Locally a length of 100mm～500mm in the thickened area of thickened area, shear wall local thickened area thickened area height be 300mm～
500mm, along longitudinally reserving multiple bolt hole, adjacent two bolts hole in coupling beam local widening district and thickened area, shear wall local
Between centre-to-centre spacing not less than 50mm, the bolt hole edge distance far from concrete edge is not less than 30mm；
Step 2, stretch-draw prestressing force bolt of long stem: by prestressing force bolt of long stem through bolt hole, then to prestressing force stock
Bolt carries out stretch-draw；
The bolt of long stem that step 3, acquisition coupling beam local widening and shear wall local thicken connects node: reaching design will
After the stretching force asked, with high-strength nut, prestressing force bolt of long stem is anchored on anchor slab, i.e. forms coupling beam local widening and shearing
The bolt of long stem that wall local thickeies connects node.
The present invention compared with prior art has the advantages that
One, dock region due to the present invention with coupling beam at shear wall to be additionally arranged shear wall thickened area, local and coupling beam local and add
Wide district so that at shear wall and coupling beam node, rigidity is big, deforms little, it is not easy to ftracture, shortens the duration.
Two, the method for the present invention makes shear wall more solid and reliable with the connection of coupling beam, compares cast-in-place method bearing capacity and carries
High by more than 50%, the application for fabricated shear wall with coupling beam node provides technical support.
Three, the method construction of the present invention is convenient, speed of application fast, construction quality is easily guaranteed that.
Four, the node of the present invention prefabricated assembled shear wall and coupling beam be applicable to frame shear wall structure connects.
