Include pillar, body of wall etc..
Precast reinforced concrete structure method of attachment of the present invention, described precast reinforced concrete structure is horizontal member, example
Such as beam or plate etc..
The present invention compared with prior art has the advantage that.
(1) the recess sidewall anchoring of first precast reinforced concrete structure of the present invention has reinforcing bar, significantly improves in groove
Rear pouring concrete and precast concrete connection integrity；The anchor of the second precast reinforced concrete structure connects reinforcing bar and can take with this reinforcing bar
Connecing or be mechanically connected or weld together, power transmission is directly, reliably；Avoid anchor in prior art connect Bar Anchorage in groove after water
In concrete, then pouring concrete and the situation of precast concrete binding ability power transmission after dependence.
(2) the recess sidewall anchoring of first precast reinforced concrete structure of the present invention has reinforcing bar, after improve in groove
Pouring concrete and precast concrete connection integrity, when in pouring concrete after having other Bar Anchorage in groove, add
Anchoring property.
(3) in the precast reinforced concrete structure such as body of wall, floor, fluting causes load action low groove at plate face
The precast concrete of sidewall is prone to peel off, and the anchor bar at this can be greatly enhanced the globality of precast concrete.
Described precast reinforced concrete structure includes but not limited to precast concrete flat board, pillar, body of wall, beam, T-shaped wall
The element types such as post, L-shaped wall column, cross wall column, trough plate.
