Description
Technical field
The invention belongs to prefabricated reinforced concrete structure technical field.
Background technology
The production efficiency of precast concrete is high, quality is good, saves resource, beneficially sustainable development.Use prefabricated
Xoncrete structure is building industrialization developing direction.
In prior art, precast reinforced concrete structure has hole, and it is real to be inserted into reinforcing bar casting concrete at hole
Connection between existing prefabricated components, connects Bar Anchorage in hole in rear pouring concrete, between rear pouring concrete and precast concrete
Connect together by conjunction old and new concret power, switching performance Shortcomings.
Summary of the invention
It is an object of the invention to improve the switching performance between precast concrete, particularly in hole after pouring concrete with
The globality of precast concrete, improves the globality of cast in place and precast construction.
For reaching above-mentioned purpose, the present invention proposes a kind of precast reinforced concrete structure, and it has at least one hole,
Hole is through hole, or the most through hole, arranges reinforcing bar in hole, and Bar Anchorage is in hole sidewalls concrete.By setting
Put hole, the globality between precast concrete and rear pouring concrete can be improved；Bar Anchorage, in hole sidewalls concrete, improves
Precast concrete and the binding ability of rear pouring concrete, and improve and the bar connecting performance in rear pouring concrete, power transmission is direct,
Stress is reliable, it is to avoid pouring concrete after Bar Anchorage is in hole in prior art, then by rear pouring concrete and concrete
The situation that soil combines.Described hole cross section is rectangle or circular or polygon, or other shapes.Described reinforcing bar exposes
Part is linear or U-shaped etc..
Described precast reinforced concrete structure has the hole intersected with described hole, and this hole is through hole or does not passes through
Via holes；After so, pouring concrete is interlocked with precast concrete, it is ensured that the binding ability between prefabricated components.When using not
During through hole, extended reinforcing bar bottom hole.
Reinforcing bar in described precast reinforced concrete structure is parallel with hole, or with hole oblique；Or reinforcing bar is with pre-
The part of concrete processed connection and hole oblique, remainder is parallel with hole.When reinforcing bar and hole oblique, can first make reinforcing bar
The precast reinforced concrete structure parallel with hole, bends reinforcing bar the most again.
The described reinforcing bar length being anchored in bottom precast reinforced concrete structure hole is not less than hole depth, or described
Reinforcing bar length is less than hole depth.
The manufacture method of precast reinforced concrete structure of the present invention, it is characterised in that comprise the following steps: that (1) is prefabricated
On reinforced concrete member production site, use bed die, backform, side form and for making steel pipe or the fiber-reinforced composite of hole
In material (FRP) pipe, mould makees template, wherein has the hole equivalently-sized with internal mold shape on backform or side form, and inner mould surface has
Conduit, the reinforcing bar being anchored in hole sidewalls concrete is placed in conduit；(2) layer concrete is smeared at inner mould surface when needing
Surface retarders；Concrete surface retarders can delay concrete curing；(3) side form, backform and bed die are combined, cloth
Putting other reinforcing bars, mould in arranging, interior mould passes backform or the hole of side form；(4) in the space of side form, backform and bed die composition
Casting concrete；(5) in extracting out after concrete reaches some strength, mould forms hole.When inner mould surface smears a layer concrete
During surface retarders, the concrete contacted with interior mould, due to the effect of concrete surface retarders, does not the most solidify, convenient extraction
Interior mould, other concrete have cured, and prevent reinforcing bar to be drawn out of or disturbance；If now rinsing hole surface with water, can be formed
Undisguisedly expect matsurface, significantly improve the binding ability of new-old concrete；(6) treat that concrete reaches to expect that intensity removes bed die, top
Mould, side form, form precast reinforced concrete structure.In order to improve fabricating quality, in step (1), the conduit of inner mould surface can be used
Space beyond reinforcing bar is filled up by dry discrete material, such as, add a small amount of cement mortar in sand, make sand can with molding,
But intensity is the lowest, outer force-disturbance is had i.e. to scatter.
When making precast concrete, interior mould includes mould in three stacked sons, mould bottom surface or top in middle son
There is conduit in face, and the reinforcing bar being anchored in hole sidewalls concrete is placed in conduit；Mould in two Aconitum carmichaeli Debx. is first extracted during mould out in extracting out,
Mould in son in the middle of extracting out again.
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 after in hole and waters
Concrete and precast concrete connection integrity；Reinforcing bar in rear pouring concrete can overlap or be mechanically connected with this reinforcing bar or weld
Together, power transmission is directly, reliably；After avoiding in prior art Bar Anchorage in hole in pouring concrete, then water after relying on mixed
Solidifying soil and the situation of precast concrete binding ability power transmission.
(2) the precast reinforced concrete structure hole surface of the present invention can be matsurface, significantly improves new-old concrete knot
The stress performance in conjunction face, improves the performance of cast in place and precast construction.When smearing concrete surface slow setting at inner mould surface concrete
During agent, retarder has delayed the final setting time of concrete, has reached higher intensity at other part concrete of prefabricated components, interior
Concrete not yet final set in mould surface concrete retarder coverage, after washing away with water, can form matsurface；The most also keep away
Collapse hole, well table surface concrete damage etc. when exempting to extract out interior mould, it is ensured that the quality of precast hollow component hole, significantly facilitate and execute
Work.
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.
