Abstract
The present invention relates to civil engineering and environment and utilization of resources field, the connection of reinforcing bar suitable for assembled architecture, the reinforcing bar connection being particularly suitable in the precast concrete column of boundling arrangement of reinforcement.Boundling arrangement of reinforcement precast concrete column replaces the more reinforcing bars arranged along column surrounding in column four corners setting tendon, and the every side arrangement of reinforced column is more than 3 reinforcing bars, thus needs at least 8 reinforcing bars.It is size-limited, slurry anchor connection can not be used.According to sleeve connection, it is also desirable at least 8 connection reinforcing bars.The present invention is in the milk using boundling half for the connection of lower prop on boundling arrangement of reinforcement precast concrete and constrains slurry anchor connection method.The connection method is the preformed hole that upper prop is inserted by the tendon that boundling arrangement of reinforcement precast concrete lower prop is reserved, and is then injected into high-strength grout, realizes and connects between boundling armored concrete upper prop and lower prop.The connection can effectively transmit the internal force that vertical and horizontal loading generates on column, reduce the connection quantity and anchorage length of vertical reinforcement.
Description
Technical field
The present invention relates to civil engineering and environment and utilization of resources field, the connection of reinforcing bar suitable for assembled architecture,
It is particularly suitable for the connection of vertical reinforcement in the precast concrete column of boundling arrangement of reinforcement.
Background technique
General constraints slurry anchor connection uses relatively broad, the connection side in prefabricated concrete structure vertically connects at present
Method has many advantages, such as securely and reliably, at low cost.However, current general constraints slurry anchor connection still has following problems: (1) reserving
The quantity of reinforced hole is too many, cause in the construction process assembly difficulty it is larger, efficiency is lower.(2) it if bar diameter is thicker, reserves
Anchorage length of steel bar is longer, leads to the production of component, and installation and difficulty of construction are larger.
Summary of the invention
The present invention proposes a kind of new to reduce the connection quantity of vertical reinforcement and shorten the anchorage length of reserved steel bar
Type connection type, the connection type can replace the more reinforcing bars or thick of column periphery arrangement using the tendon formed compared with fine steel rib
Reinforcing bar, thus reduce the connection quantity of vertical reinforcement and shorten the anchorage length of reserved steel bar, so that assembly is simpler, efficiency
It improves, while also reducing site operation installation difficulty, can preferably be applied in practice in engineering.
The constraint slurry anchor connection method the technical scheme adopted by the invention is that boundling half is in the milk, by upper layer concrete column, under
Slip casting composition between layer concrete column and upper and lower layer precast concrete column；Upper layer concrete column include upper prop boundling reinforcing bar,
The slip casting of the preformed hole, upper prop concrete, tie hoop, the grout outlet of upper prop preformed hole upper end, upper prop preformed hole lower end of upper prop
Mouthful；Lower-layer concrete column includes the reserved boundling reinforcing bar of lower prop, lower prop concrete, tie hoop.Installation method are as follows: mix upper layer
The preformed hole of solidifying earth pillar is directly directed at the reserved tendon of lower prop and falls, using dedicated adjustment device adjustment column position and vertically
Degree, it is fixed after adjustment, and with behind the upper and lower prefabricated dress concrete column gap of layer of high-strength fast hard mortar closure, it is infused in reserved grouting port
Slurry, until grout outlet pulp, the boundling half for finally completing prefabricated post, which is in the milk, constrains slurry anchor connection.
Under normal circumstances, the more reinforcing bars arranged along column periphery are replaced in column four corners location arrangements boundling reinforcing bar.And
The outer diameter of lower prop reserved steel bar beam should be identical as the internal diameter of upper prop preformed hole, and reserved steel bar beam outer diameter tolerance is minus tolerance, in advance
Internal diameter tolerance of boxing out is principal-employment.
The preformed hole upper and lower side of upper prop is respectively provided with grout outlet and grouting port, and uses pvc pipe as the drainage pipe of slurry,
According to the diameter and depth of reserving hole, the grouting port and grout outlet of different-diameter are set；According to the grouting equipment of different model
The rubber sleeve of different-diameter is selected, guarantees the connection of grouting equipment and grouting port.
After adopting the above scheme, 1. precast concrete columns of the invention are had the advantages that compared with prior art
Vertical connection method reinforcing bar replaces more of column periphery arrangement compared with bar reinforcement by the tendon formed compared with fine steel rib, can reduce perpendicular
To the connection quantity of reinforcing bar and the anchorage length of shortening reserved steel bar, the difficulty of installation and construction is greatly reduced.2. needle of the present invention
It is in the milk to boundling arrangement of reinforcement precast concrete column using boundling half and constrains slurry anchor connection method, make boundling reinforcing bar, the spiral hoop of upper prop
The reserved steel bar beam and concrete of muscle, lower prop, form firm effect of contraction, enhance boundling arrangement of reinforcement precast concrete column
Bearing capacity and deformability.

Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention will be further described:
Of the present invention is half grouting constraint slurry anchor connection method of boundling, by upper layer concrete column, lower-layer concrete
Slip casting composition between column and upper and lower layer precast concrete column；Upper layer concrete column include upper prop boundling reinforcing bar, upper prop it is pre-
Box out, upper prop concrete, tie hoop, the grout outlet of upper prop preformed hole upper end, upper prop preformed hole lower end grouting port；Lower layer is mixed
Solidifying earth pillar includes the reserved boundling reinforcing bar of lower prop, lower prop concrete, tie hoop.Installation method are as follows: by upper layer concrete column
Preformed hole is directly directed at the reserved tendon of lower prop and falls, using dedicated adjustment device adjustment column position and verticality, after adjustment
It is fixed, and after blocking the upper and lower prefabricated dress concrete column gap of layer with high-strength fast hard mortar, in reserved grouting port slip casting, up to out
Mouth pulp is starched, the boundling half for finally completing prefabricated post, which is in the milk, constrains slurry anchor connection.
