The invention discloses a multi-story and high-rise frame space joint core area PC steel bar reinforcing device. The multi-story and high-rise frame space joint core area PC steel bar reinforcing device comprises a space joint column beam, and a left reinforcing seat is mounted on the left side of the space joint column beam. A first connecting groove is formed in the upper end of the left reinforcing seat. A steel bar is mounted in the left reinforcing seat, and a square block is arranged at the left end of the steel bar. A right reinforcing seat is mounted on the right side of the space joint column beam. A second connecting groove is formed in the upper end of the right reinforcing seat. According to the multi-story and high-rise frame space joint core area PC steel bar reinforcing device, the left reinforcing seat and the right reinforcing seat are designed to reinforce the space joint column beam, and mainly the steel bar is mounted for connecting; during connecting, a square groove is designed in the left reinforcing seat and is matched with a square block of the steel bar, and therefore the steel bar cannot rotate; and a fastening nut is mounted at the right end of the steelbar, an elastic sheet and a clamping block are designed on the nut, the clamping block is matched with the clamping groove in the right reinforcing seat, the fastening nut is prevented from rotating,and therefore threaded connection of the steel bar and the nut is stable and reliable, and loosening is not likely to happen.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a PC steel bar reinforcement device for the core area of a multi-high-rise frame space node. Background technique [0002] In construction engineering, reinforced concrete frame structures are widely used for their superior seismic performance. Among them, the main beam joint is an important part of the frame structure, which plays the role of transmitting and distributing internal forces and ensuring the integrity of the structure. [0003] At present, reinforcement measures have been adopted many times to reinforce the core area of the frame space node. The patent announcement number "CN102518315 B" proposes a PC steel bar reinforcement device for the core area of the multi-high-rise frame space node, and assembles the support members through the thread cooperation of the steel bars. However, the thread lacks stabilization measures, and there is a risk ...
