Method.The method of attachment that the present invention proposes can ensure between precast reinforced concrete structure, interlayer connection integrity, easy construction,
Improve the performance of assembled monolithic concrete structure.
A kind of precast reinforced concrete structure method of attachment, by precast reinforced to the first precast reinforced concrete structure and second
Concrete component is linked to be entirety, described first precast reinforced concrete structure has at least one hole, fills out in described hole
Fill retarding mortar；Arranging reinforcing bar in described hole, described Bar Anchorage is in hole sidewalls concrete；Bar Anchorage is in hole 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 hole in prior art,
Situation about being combined by rear pouring concrete and precast concrete again；Described hole cross section is that rectangle is circular or polygon
Shape, or other shapes；Described reinforcing bar exposed portion is linear or U-shaped etc..On described second precast reinforced concrete structure
Stretch out anchor and connect reinforcing bar.First precast reinforced concrete structure and the second precast reinforced concrete structure be installed, described second prefabricated
The anchor of reinforced concrete member connects reinforcing bar and stretches in described hole, and described anchor connects reinforcing bar near the first precast reinforced concrete structure
Reinforcing bar in hole, or overlap, overlap.Ensure that anchor connects in reinforcing bar and hole by modes such as prefabricated components side vibrations
Grouting material is closely knit.After retarding mortar solidification, the first precast reinforced concrete structure and the second precast reinforced concrete structure are linked to be
Overall.
In existing assembled monolithic concrete structure, after prefabricated components arrange hole, the most at the construction field (site) in hole
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 hole, 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 hole end can be provided with the closure closing described hole, does not passes through
One end of via holes or the two ends of through hole arrange closure, such as metal paper tinsel on hole mouth surrounding concrete, or
Rubber stopper etc. is filled at aperture.When installing the second precast reinforced concrete structure, described closure 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
Hole be through hole, or be the most through hole.Reinforcing bar in described hole is parallel with hole, or with hole oblique.
In described hole, reinforcing bar stretches out hole, or described reinforcing bar does not extends out hole.
In 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 the precast reinforced concrete structure of the present invention has reinforcing bar, significantly improves slow setting in hole
Mortar and precast concrete connection integrity；The reinforcing bar of rear insertion hole 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 hole 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 at hole sidewalls, in hole, pour retarding mortar
Realize the connection between different precast reinforced concrete structure.In hole 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 hole；And the present invention, in hole, insert retarding mortar, this
One operation completes in factory, or completes before lifting component is in place, it is to avoid again in hole after precast reinforced concrete structure installation
Casting concrete in hole, 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 under load action hole 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.
