Deng.
The present invention compared with prior art has the advantage that.
(1) the recess sidewall anchoring of first precast concrete of the present invention has reinforcing bar, significantly improves after in groove and waters
Concrete and precast concrete connection integrity；The anchor of the second precast concrete connects reinforcing bar and can overlap with this reinforcing bar or machinery
Connecting or weld together, power transmission is directly, reliably；Anchor in prior art is avoided to connect Bar Anchorage rear pouring concrete in groove
In, then pouring concrete and the situation of precast concrete binding ability power transmission after dependence.
(2) the recess sidewall anchoring of first precast concrete of the present invention has reinforcing bar, improve water after in groove mixed
Solidifying soil and precast concrete connection integrity, when in pouring concrete after having other Bar Anchorage in groove, add anchoring
Performance.
(3) in the precast concrete such as body of wall, floor, fluting causes the pre-of sidewall at load action recessed frid face
Concrete processed is prone to peel off, and the anchor bar at this can be greatly enhanced the globality of precast concrete.
Described precast concrete includes but not limited to precast concrete flat board, pillar, body of wall, beam, T-shaped wall column, L-shaped
The element types such as wall column, cross wall column, trough plate.
