Concrete component is linked to be entirety, described first precast reinforced concrete structure has at least one groove, fills out in described groove
Fill retarding mortar；Arranging reinforcing bar in described groove, described Bar Anchorage is in recess sidewall concrete；Bar Anchorage is at groove side
In wall concrete, improve the binding ability of precast concrete and retarding mortar, and with the bar connecting stretched in retarding mortar or
Overlap joint improves switching performance, and power transmission is direct, and stress is reliable, it is to avoid pouring concrete after Bar Anchorage is in groove in prior art,
Combined the situation of overlap joint indirectly again by rear pouring concrete and precast concrete；Described channel section is rectangle or circle
Or polygon, or other shapes；Described reinforcing bar exposed portion is linear or U-shaped etc..Described second prefabricated reinforced concrete
Stretch out anchor on component and connect reinforcing bar.First precast reinforced concrete structure and the second precast reinforced concrete structure be installed, described
The anchor of two precast reinforced concrete structures connects reinforcing bar and stretches in described groove, and described anchor connects reinforcing bar near the first precast reinforced coagulation
Reinforcing bar in soil component hole, or overlap, overlap.By the modes such as prefabricated components side vibration ensure anchor connect reinforcing bar with
In groove, grouting material is closely knit.By the first precast reinforced concrete structure and the second prefabricated reinforced concrete structure after retarding mortar solidification
Part is linked to be entirety.
In existing assembled monolithic concrete structure, after prefabricated components arrange groove, the most at the construction field (site) in groove
Insert reinforcing bar, casting concrete.In the present invention, retarding mortar can delay solidify, in factory by slow setting for some hours or some days
Mortar is inserted in groove, and reinforcing bar is inserted retarding mortar by job site, it is to avoid the concrete works of building-site, improves prefabricated knot
Structure easy construction.For avoiding retarding mortar to reveal, described groove ends or top can be provided with the closing closing described groove
Thing, such as metal paper tinsel on groove port surrounding concrete, or filling in rubber stopper etc., or use false form.Installing
During the second precast reinforced concrete structure, the closure of groove top is removed.
Described second precast reinforced concrete structure is arranged on the first precast reinforced concrete structure top, or described
Two precast reinforced concrete structures are arranged on the first precast reinforced concrete structure bottom.On first precast reinforced concrete structure
Groove be through groove, or be the most through groove.Reinforcing bar in described groove is parallel with groove, or with groove oblique.
In described groove, reinforcing bar stretches out groove, or described reinforcing bar does not extends out groove.
Precast concrete method of attachment of the present invention, described bottom portion of groove stretches out reinforcing bar.
Precast concrete method of attachment of the present invention, described recess sidewall arranges hole；The hole of described recess sidewall
For through hole, or it it is the most through hole.
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 recess sidewall anchoring of the precast reinforced concrete structure of the present invention has reinforcing bar, significantly improves slow setting in groove
Mortar and precast concrete connection integrity；The reinforcing bar of rear insertion groove and this reinforcing bar can overlap or be mechanically connected or be welded on one
Rising, power transmission is directly, reliably；After avoiding in prior art the connection Bar Anchorage between prefabricated components in groove in pouring concrete,
Pouring concrete and the situation of precast concrete binding ability power transmission after relying on again.
(2) present invention provides a kind of convenience, carries out the precast reinforced concrete structure company of connection between different component reliably
Connect method.By perforate on precast reinforced concrete structure, and stretch out reinforcing bar in recess sidewall, in groove, pour retarding mortar
Realize the connection between different precast reinforced concrete structure.In groove can with the bar splicing of adjacent members, be mechanically connected, weld
Connect.
(3) present invention provides the prefabricated reinforced concrete method of attachment that a kind of industrialized level is high.Perforate in prior art
During prefabricated components wet connection, building-site is casting concrete in groove；And the present invention, in groove, insert retarding mortar, this
One operation completes in factory, or completes before lifting component is in place, it is to avoid again recessed after precast reinforced concrete structure installation
Casting concrete in groove, reduces the concrete works of building-site；After in-site installation, retarding mortar gradually solidifies, by pre-manufactured steel
Reinforced concrete component connects into entirety；According to condition of construction, the setting time of retarding mortar can be from some hours to some skies.
(4) in the precast reinforced concrete structure such as body of wall, floor, perforate 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.
