Description
Technical field
The invention belongs to prefabricated reinforced concrete structure technical field, it is adaptable to assembled monolithic concrete structure system.
Background technology
Precast concrete is to be suitable for industrialized version.Prefabricated structure in assembly integrated precast concrete structure
Connecting structure between part determines integrality performance of the structure.In existing precast concrete, the connection node between component is usually
The weak link of structure, affects stress performance；Bar connecting between the upper and lower prefabricated components of precast construction uses reinforced bar sleeve at present
Grouting connection, slurry anchor connection etc., work progress is complicated, construction quality is difficult to ensure.
Connection between existing prefabricated components is usually at lower member reserved steel bar, is inserted in upper component, such as steel
The technology such as muscle sleeve grouting connection, slurry anchor connection are by lower wall body Bar Anchorage in upper wall body, and grouting needs pressure, grouting
Quality is difficult to ensure, constructs complex.
Summary of the invention
The present invention provides the connection between the prefabricated components of the good precast concrete of a kind of easy construction, stress performance
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 groove, fills out in described groove
Fill retarding mortar (retarding mortar fills up groove or is partially filled with groove as required)；Reinforcing bar is set in described groove, described
Bar Anchorage is in recess sidewall concrete；Bar Anchorage, in recess sidewall concrete, improves precast concrete and slow setting sand
The binding ability of slurry, and switching performance can be improved with the bar connecting in rear pouring concrete or overlap joint, power transmission is direct, and stress can
Lean on, it is to avoid pouring concrete after Bar Anchorage is in groove in prior art, then be combined with precast concrete by rear pouring concrete
Situation together；Described channel section is rectangle or circular or polygon, or other shapes.Described reinforcing bar exposed portion is
Linear or U-shaped etc..There is concrete protruding on described second precast reinforced concrete structure.First prefabricated reinforced concrete is installed
Component and installation the second precast reinforced concrete structure, the projection of described second precast reinforced concrete structure is completely or partially stretched
Entering in described groove, in can ensureing groove by modes such as prefabricated components side vibrations, grouting material is closely knit；After retarding mortar solidification
First precast reinforced concrete structure and the second precast reinforced concrete structure are linked to be entirety.Described second precast reinforced coagulation
Soil component is arranged on the first precast reinforced concrete structure top, or described second precast reinforced concrete structure is arranged on the
One precast reinforced concrete structure bottom.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.
In existing cast in place and precast construction, after prefabricated components arrange groove, it is inserted at groove the most at the construction field (site)
Reinforcing bar, casting concrete.In the present invention, retarding mortar can delay solidify, in factory by retarding mortar for some hours or some days
Inserting in groove, reinforcing bar is inserted retarding mortar by job site, it is to avoid the concrete works of building-site, improves precast construction and executes
Work convenience.For avoiding retarding mortar to reveal, described groove top or two ends are provided with the closure closing described groove, such as
Metal paper tinsel etc. on groove port surrounding concrete, or template is set, or at aperture, fill in rubber stopper etc..Installing second
During precast reinforced concrete structure, the closure of groove top is removed.
Precast reinforced concrete structure method of attachment of the present invention, the protruding end of described second precast reinforced concrete structure
Stretching out anchor and connect reinforcing bar, anchor connects reinforcing bar length and meets force request.After projection stretches into groove, it is precast reinforced near first that anchor connects reinforcing bar
Reinforcing bar in concrete component hole, or overlap, link together.
Precast reinforced concrete structure method of attachment of the present invention, bottom described first precast reinforced concrete structure upper groove
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 recess sidewall anchoring of first precast reinforced concrete structure of the present invention has reinforcing bar, significantly improves in groove
Retarding mortar and precast concrete connection integrity；The anchor of the second precast reinforced concrete structure connects reinforcing bar and can overlap with this reinforcing bar
Or be mechanically connected or weld together, power transmission is directly, reliably；Avoid anchor in prior art connect Bar Anchorage in groove after water mixed
In solidifying soil, 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
Retarding mortar and precast concrete connection integrity, when there being other Bar Anchorage in retarding mortar in groove, add anchor
Solidity energy.
(3) second precast reinforced concrete structure of the present invention arranges projection, extend into the first prefabricated reinforced concrete structure
In the groove of part, add shear behavior and the tensile property of junction.
(4) 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.
(5) groove at the first precast reinforced concrete structure fills retarding mortar, installs the second prefabricated reinforced concrete
During component, projection stretches in groove, compacted concrete or grouting material, can no longer vibrate and can ensure concrete or grouting material and
Density between two precast concretes (including that anchor connects reinforcing bar or concrete)；The concrete or the grouting material that are extruded are filled out simultaneously
Fill between the first precast reinforced concrete structure and the second precast concrete, add the globality between component.
(6) 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.
