Description
Technical field
The present invention relates to field of civil engineering, the preparation dress of specifically a kind of prefabricated connecting hole suitable for fabricated construction
Put and its using method.
Background technology
In the today for advocating sustainable development and energy-saving and emission-reduction, assembled architecture due to energy-conserving and environment-protective low in the pollution of the environment and into
This is relatively low and advocated energetically.In assembled architecture, means of structural connection is various, wherein grouting anchor connection because easy to connect,
It is aesthetic in appearance, little being widely adopted is affected by space enrironment.And it is current, grout hole is reserved in grouting anchor connection be mostly interior spiral shell
Stricture of vagina or round straight hole.Female thread pre-manufactured hole needs the pre-buried corrugated tubing before concreting, but deposits between corrugated tubing and concrete
In certain bond-anchorage problem.The anchorage effect between back-grouting body and former concrete in round straight hole is unreliable, therefore many
The accessory such as Cast-steel Sleeve of additional configuration reinforced joint connection in the grout hole, not only complex manufacturing technology, and involve great expense,
Steel quantity consumption is big.
In view of this, inventor is had made intensive studies to the connecting hole preparation method of grouting anchor precast construction, then
There is this case to produce.
The content of the invention
It is an object of the invention to provide a kind of structure is novel, the preparation facilitiess of prefabricated convenient prefabricated connecting hole.
It is a further object of the present invention to provide a kind of using method of the preparation facilitiess of the prefabricated connecting hole of simple operation.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of preparation facilitiess of prefabricated connecting hole, including thimble assembly, described sleeve pipe component include hollow pipe and have bullet
The plastic casing-pipe of property, the plastic casing-pipe is placed on outside the hollow pipe, and the plastic casing-pipe is connected with the hollow pipe, institute
State, the hollow pipe is connected with a water injection valve.
A plurality of permeable holes are offered on the tube wall of the hollow pipe, the plastic casing-pipe is provided with a plurality of described first about
Beam ring, the permeable hole is corresponding with first confinement ring to distribute alternately.
Along each described permeable hole and each first confinement ring of the axial direction of described sleeve pipe component, difference is equally
Distribution.
Also include that the top closure of the hollow pipe has a cover plate, described for fixing the fixed plate of described sleeve pipe component
The nose end of plastic casing-pipe extends the installation portion to form shade shape, and the cover plate of the hollow pipe and the fixed plate offer peace
Dress hole, the hollow pipe, the plastic casing-pipe and the fixing pipe are locked by the cooperation of the installing hole and locking member respectively
Together.
The water injection valve is on the cover plate of the hollow pipe；The middle part of the installation portion forms and penetrates for the hollow pipe
Through hole, the external diameter phase close-fitting of the through hole and the hollow pipe.
First confinement ring is non-elastic structure or low elasticity structure.
It is provided near the position of the installation portion in the plastic casing-pipe and avoids the connection end generation of the plastic casing-pipe swollen
The second swollen confinement ring.
A kind of using method of the preparation facilitiess of prefabricated connecting hole, comprises the steps：
1) releasing agent is coated on the lateral wall of the plastic casing-pipe；
2) water injection valve is opened to water filling in the hollow pipe, water injects the plastic casing-pipe by the permeable hole,
The plastic casing-pipe produces expansion, and due to the effect of contraction of first confinement ring, the plastic casing-pipe after water filling is in concavo-convex
Shape, closes the water injection valve after the completion of water filling, water under high pressure is filled with the plastic casing-pipe；
3) to casting concrete in the template of prefabricated components, and molding is conserved, then opens water injection valve, water under high pressure is banished
Fall, plastic casing-pipe natural shrinking, be rapidly separated concrete, and then the inside concrete for pouring forms prefabricated concavo-convex connection
Hole.
A kind of preparation facilitiess of prefabricated connecting hole of the present invention, its can before prefabricated components casting concrete processing and fabricating,
Structure manufacture batch production and standardization are realized, and it is simple and convenient.Carried out by hollow pipe in prefabricated components casting concrete
Support, prevent plastic casing-pipe because intensity is not enough integrated deflection.After pressure water injection, water injection valve can cut out, it is ensured that construction quality, prevent
Only the water under high pressure inside plastic casing-pipe flows out, and produces deformation.
Preparation facilitiess in the present invention when in use, can expand to form a-circle-by-a-circle bulge loop and groove after water filling pressurization
The convex-concave shape for distributing alternately, and then prefabricated connecting hole is concavo-convex, can increase the machinery between grouting body and former concrete
Gmatjpdumamicss, the shearing resistance increased after pre- slurrying anchor component connection is anti-pull-out property.
Plastic casing-pipe lateral wall scribbles releasing agent, and water injection valve is opened, and the water under high pressure in plastic casing-pipe releases.Treat garment bag
After managing automatic retraction original-shape, plastic casing-pipe is disengaged automatically with peripheral concrete, and the demoulding is simply efficient.
When needing to prepare multiple prefabricated connecting holes simultaneously, can be by pre-aligned fixed plate, with bolt hollow
Pipe and plastic casing-pipe are tightened against in fixed plate, you can be accurately positioned.
