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 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 through hole, arranges steel in described hole
Muscle, described Bar Anchorage is in hole sidewalls concrete；By arranging hole, can improve between precast concrete and rear pouring concrete
Globality；Bar Anchorage in hole sidewalls concrete, improve precast concrete with after water the knot of concrete in hole
Closing performance, and can improve switching performance together with the bar connecting in rear pouring concrete, power transmission is direct, and stress is reliable, it is to avoid
Pouring concrete after Bar Anchorage is in hole in prior art, then combined by rear pouring concrete and precast concrete
Situation；Described hole cross section is rectangle or circular or polygon, or other shapes.Described reinforcing bar exposed portion be linear or
U-shaped etc..Having concrete protruding on described second precast reinforced concrete structure, protruding end is stretched out anchor and is connected reinforcing bar；Install first
Precast reinforced concrete structure, fill concrete or grouting material in described hole, then the second prefabricated reinforced concrete structure is installed
Part, the projection of described second precast reinforced concrete structure completely or partially stretches in described hole；It is close that described anchor connects reinforcing bar
Reinforcing bar in first precast reinforced concrete structure hole, or connect, overlap；By the after concrete or grouting material hardening
One precast reinforced coagulation concrete component and the second precast reinforced coagulation concrete component are linked to be entirety.Described second precast reinforced
Concrete component is arranged on the first precast reinforced concrete structure top, or described second precast reinforced concrete structure is installed
In the first precast reinforced concrete structure bottom.Reinforcing bar in described hole is parallel with hole, or with hole oblique.Described hole
In 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, stretches out reinforcing bar bottom described 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 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 anchor in prior art connect Bar Anchorage in hole after water
In 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) second precast reinforced concrete structure of the present invention arranges projection, extend into the first prefabricated reinforced concrete structure
In the hole of part, add shear behavior and the tensile property of junction.
(4) at hole elder generation fill concrete or the grouting material of the first precast reinforced concrete structure, pre-relative to by first
Reinforced concrete member processed and the second precast reinforced concrete structure install after casting concrete in hole again, more convenient execute
Work.And when installing the second precast reinforced concrete structure, projection stretches in hole, compacted concrete or grouting material, can be no longer
Vibrate can ensure between concrete or grouting material and the second precast concrete (including that anchor connects reinforcing bar or concrete) closely knit
Property；The concrete being simultaneously extruded or grouting material are filled in the first precast reinforced concrete structure and the second precast concrete
Between, add the globality between component..
(5) in the precast concrete such as body of wall, 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.
