A kind of precast reinforced concrete structure method of attachment, by the first precast concrete and the second precast concrete structure
Part is linked to be entirety, described first precast reinforced concrete structure has at least one hole, arranges reinforcing bar in described hole, institute
State Bar Anchorage in hole sidewalls concrete；By arranging hole, that can improve between precast concrete and rear pouring concrete is whole
Body；Bar Anchorage in hole sidewalls concrete, improve precast concrete with after pour into the associativity of concrete in hole
Can, can be by improving bar connecting performance with the bar splicing being arranged in rear pouring concrete or be connected etc., power transmission is direct, stress
Reliably, it is to avoid by Bar Anchorage rear pouring concrete in hole in prior art, then by rear pouring concrete and precast concrete
Situation about combining；Described hole cross section is rectangle or circular or polygon, or other shapes.Described reinforcing bar exposed division
It is divided into linear or U-shaped etc..Stretch out anchor on described second precast reinforced concrete structure and connect reinforcing bar.First install first precast reinforced
Concrete component, fill concrete or grouting material in described hole, then the second precast reinforced concrete structure is installed, described
The anchor of two precast reinforced concrete structures connects reinforcing bar and stretches in described hole, and described anchor connects reinforcing bar near the first precast reinforced coagulation
Reinforcing bar in soil component hole, or overlap, link together.By the modes such as prefabricated components side vibration ensure anchor connect reinforcing bar with
Hole inner concrete or grouting material are closely knit.By the first precast reinforced coagulation concrete component and the after concrete or grouting material hardening
Two precast reinforced coagulation concrete components are linked to be entirety.It is precast reinforced that described second precast reinforced concrete structure is arranged on first
Concrete component top, or described second precast reinforced concrete structure is arranged under the first precast reinforced concrete structure
Portion.Hole on first precast reinforced concrete structure is through hole, or is the most through hole.Reinforcing bar in described hole
Parallel with hole, or with hole oblique.In described hole, reinforcing bar stretches out hole, or described reinforcing bar does not extends out hole.
Precast reinforced concrete structure method of attachment of the present invention, described first precast reinforced concrete structure has hole
Hole；When described hole is the most through hole, bottom hole, stretch out reinforcing bar.
Precast reinforced concrete structure method of attachment of the present invention, described precast reinforced concrete structure is vertical member, bag
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.
The present invention compared with prior art has the advantage that.
(1) the hole sidewalls anchoring of first precast reinforced concrete structure of the present invention has reinforcing bar, significantly improves in hole
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 that anchor is connected reinforcing bar reinforcing bar by prior art and be anchored at hole
After in pouring concrete, then pouring concrete and the situation of precast concrete binding ability power transmission after dependence.
(2) the hole sidewalls anchoring of first precast reinforced concrete structure of the present invention has reinforcing bar, after improve in hole
Pouring concrete and precast concrete connection integrity, when in pouring concrete after having other Bar Anchorage in hole, add
Anchoring property.
(3) at hole elder generation fill concrete or grouting material, the convenient construction of the first precast reinforced concrete structure.
(4) in the precast concrete such as wallboard, floor, perforate causes hole sidewall at plate face under load action
Precast concrete be prone to peel off, 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.
