Background
The construction quality of major structure beam column node plays very important effect to overall structure's security, at present in concrete placement construction, meets very easily and leads to the problem that the concrete is difficult to the pouring because of structural reinforcement is intensive, if the treatment is improper, very easily causes the not closely knit consequence of concrete in the intensive region of main structural reinforcement.
In the prior construction process, measures such as reducing the particle size of coarse aggregate, properly improving the slump of concrete, prying off dense reinforcing steel bars, vibrating by using a small first vibrating rod, vibrating for the second time before the initial setting of the concrete and the like are also adopted. However, once the concrete blocks in the dense area of the reinforcing steel bars at the beam-column joint which is not easy to be touched by people, the coarse aggregate is deposited on the upper part of the dense reinforcing steel bars, and the cement and the fine aggregate in the concrete flow to the bottom of the column in the form of slurry, so that the concrete is separated, and the pouring construction quality is influenced.
