Technical solution is used by the utility model solves its technical problem：A kind of prefabricated reinforced concrete column connection
Construction, it is characterised in that
On the basis of cross-section prefabricated stand column, taken in prefabricated stand column end and expand head processing, formed and expand head section at the top of column
Expand head section with column bottom；
Column bottom expands head section bottom end face and sets groove, stretches out embedded bar in groove, makes its pre-buried steel with cushion cap
Muscle mutually overlaps, and pours into a mould the concrete in groove, prefabricated stand column is linked to be overall structure with cushion cap or prefabricated bent cap；
Expand head section at the top of column or/and prefabricated bent cap bottom set groove, stretch out embedded bar in groove, make its with it is prefabricated
The embedded bar of bent cap or/and prefabricated stand column mutually overlaps, and pours into a mould the concrete in groove, prefabricated stand column is connected with prefabricated bent cap
Integral structure.
Further, grout hole and slurry outlet are set in the groove, it is ensured that concrete cast is closely knit in groove.
Further, prolong the lower end of the longitudinally disposed grout hole of the prefabricated bent cap and slurry outlet, grout hole and slurry outlet
The groove for expanding head section or prefabricated bent cap bottom at the top of column is extended, upper end then extends to preform lid top surface of the beam.
Further, the column bottom, which expands, sets inclined-plane linkage section between head section and column, the inclined-plane linkage section is oblique
To setting grout hole and slurry outlet, the lower end of grout hole and slurry outlet extends to column bottom and expands head section groove, and upper end then extends
To the side of the inclined-plane linkage section.
Further, the concrete is ultra high performance cementitious.
Compared with prior art, the beneficial effects of the utility model are：
First, the prefabricated reinforced concrete post end of the utility model, which is taken, expands head processing, increases column sectional dimension,
When prefabricated stand column or prefabricated bent cap are installed, simple interim auxiliary fixation need to be only taken, improves prefabricated stand column installation
Structure homeostasis on to cushion cap or when prefabricated bent cap is installed on prefabricated stand column.
2nd, the prefabricated reinforced concrete column expansion head section of the utility model takes groove to design, and pre-buried steel is stretched out in groove
After muscle, prefabricated stand column or the lifting positioning of prefabricated bent cap, pour into a mould the ultra-high performance concrete in groove, make prefabricated stand column and cushion cap or
Prefabricated bent cap is linked to be overall structure, avoids the template that prefabricated stand column is poured into a mould with cushion cap or the concrete of prefabricated bent cap junction and takes
Rhetoric question is inscribed, and accelerates component connection speed.
