Setting beam widens area, precast beam connect with prefabricated post the back rest widen area end face outside be arranged there are one anchor slab, multiple prestressing force
Bolt of long stem widens area and prefabricated post through beam, and each prestressing force bolt of long stem both ends are fastened with high-strength nut, and multiple stirrups are equal
Cloth is arranged on the upper surface in precast beam local widening area.
The bolt of long stem of the present invention widens the bean column node connection method in area through beam side, and the method is by following step
Suddenly it realizes：
Step 1: beating bolt hole on precast beam and prefabricated post：The beam of precast beam is widened into area and beats multiple beam spiral shells along longitudinal direction
Keyhole beats multiple stud bolt holes in the region that prefabricated post is connect with precast beam, and multiple stud bolt holes and multiple beam bolt holes are one by one
It is corresponding；
Step 2: connection precast beam and prefabricated post：Precast beam is lifted into the join domain of prefabricated post, and is made on precast beam
Multiple beam bolt holes be aligned one by one with multiple stud bolt holes in prefabricated post, prestressing force bolt of long stem pass through beam bolt hole and column
Bolt hole, and the reserved last-cost joint between precast beam and prefabricated post；
Step 3: smearing silicone weather resistant glue：At last-cost joint between precast beam and prefabricated post silicon will be smeared along edge circumferential direction
Ketone weather-resistant glue, there are openings at the silicone weather resistant glue that top edge is smeared；
Step 4: cast mortar：Hollow light wall pipe is inserted between prestressing force bolt of long stem and beam bolt hole and stud bolt hole,
Mortar is continuously noted into last-cost joint from opening, and is filled；
Step 5: installation high-strength nut：After body condensation, high-strength spiral shell is installed at prestressing force bolt of long stem both ends
Mother, and tighten；
Step 6: installing multiple stirrups：Multiple stirrups are uniformly arranged on the upper surface in precast beam local widening area, and
Stirrup is fixed on precast beam by casting concrete, and so far, the node for completing precast beam and prefabricated post connects.
The present invention has the advantages that compared with prior art：
One, node of the invention is to be additionally arranged beam in precast beam and prefabricated post join domain to widen area, passes through bolt of long stem
Beam through beam side widens the beam-column connection in area, reduces existing difficulty of construction and working strength, it is easier to structural elements
Installation positioning, and then reduce project cost, accelerate speed of application.
Two, method of the invention is to devise last-cost joint in precast beam and prefabricated post junction, by noting sand to last-cost joint
Slurry comes reinforced cementitious so that the connection of precast beam and prefabricated post is more solid and reliable, strengthens the globality of beam-to-column joint.
Three, method construction technology of the invention is simple, does not need complicated construction machinery.
