The prefabricated beam end lower part is equipped with outstanding step, sink the step with outstanding step reservation reinforcing bar hole, prefabricated beam both ends lower part is equipped with outstanding step, sink the step with outstanding step reservation reinforcing bar hole, prefabricated roof beam erects on one side of the prefabricated post, the reservation hole corresponds each other for pass the connecting reinforcement.
And pin plate grooves are reserved at the rear parts of the sunken step and the protruding step, after the connecting steel bars penetrate through the reserved holes, epoxy glue is coated on the part of the pin plate inserted into the pin plate grooves, and then the pin plate is inserted into the reserved pin plate to support the end nuts.
The two ends of the connecting steel bar are provided with thread sections, the precast beam is arranged in the empty groove when not hoisted in place, and after being hoisted in place, the precast beam penetrates through the preformed hole and is tightly propped against the C-shaped anchor on the column side.
And the nut is timely screwed on the thread sections at the two ends of the connecting steel bar after the connecting steel bar penetrates through the preformed hole, and the nut is further screwed after the connecting steel bar is in place and clings to the column side, the sunken step and the protruding step so as to transfer the tension of the connecting steel bar.
The length of the end nut is three times of that of a common nut with the same specification, an end plate slightly larger than the nut is arranged at one end of the end nut, the end nut is tightly screwed on a threaded section at one end of the hollow groove of the connecting steel bar before the bolt plate is inserted into the bolt groove, and after the bolt plate is inserted into the bolt groove, the end nut is unscrewed towards the hollow groove and is tightly attached to the bolt plate in the long hollow groove, so that the pressure of the connecting steel bar is transferred.
Has the advantages that:
compared with the prior art, the invention has the following advantages.
(1) The prefabricated wood structure frame beam column joint is formed by connecting the nuts and the threads, the mounting efficiency is high, and the construction speed is high.
(2) When the precast beam is not installed, the connecting steel bars are not installed, and after the precast beam is installed in place, the connecting steel bars penetrate through the preformed holes and only work for screwing bolts and installing the bolt plates, so that the method is simple, convenient and quick, and high in efficiency.
(3) The connecting reinforcing steel bar can effectively transmit tension and pressure to form rigid connection, so that the stress performance of the beam-column connecting node is ensured, meanwhile, the connecting reinforcing steel bar is not bonded in a pore channel, has good deformability and higher anti-seismic energy consumption capacity, and can effectively ensure the structural performance of the connecting node under the action of seismic load.
