The sleeve grouting material 13 that grouting port flows into, grout outlet flows out is crossed, the grouting port and grout outlet are blocked by plug,
The reinforcing bar grout sleeve of the grout outlet obliquely in the prefabricated components of upside be equipped with two rows, respectively inner barrel 1a and
The grout outlet of outer barrel 1b, the inner barrel 1a are directly connected to the outer wall of upper layer prefabricated components 9 with grouting port, described outer
The grout outlet of side sleeve 1b is connected to upper layer prefabricated components 9 by pulp extension tube 14 with slip casting extension tube 15 respectively with grouting port
Outer wall, slip casting extension tube 15 is horizontally disposed, and pulp extension tube 14 is arranged obliquely along the setting direction of grout outlet.
The construction method of the connection structure of the reinforcing bar grout sleeve of this grout outlet obliquely, construction procedure are as follows：
Step 1, according to the diameter of lower layer's reinforcing bar 12 and top bars 11 determine reinforcing bar be in the milk the diameter of branch sleeve, wall thickness and
Then length is molded in factory process.
Step 2, it is by design requirement that lower layer's reinforcing bar 12 and top bars 11 is pre- in lower layer's prefabricated components 10 and upper layer respectively
It processes and binds in component 9 processed, one group of reinforcing bar is then in the milk branch sleeve and the corresponding extension tubes of outer barrel 1b 14 are fixed
At the position preset to upper layer prefabricated components 9, the direction of pulp extension tube 14 and grout outlet is in alignment to install obliquely,
Simultaneously using the length of linear measure longimetry steel ruler record grout outlet 3 and pulp extension tube 14.

Enter in the reinforcing bar grouting branch sleeve in upper layer prefabricated components 9, and is sealed using rubber plug.
Step 5 prepares sleeve grouting material 13, from grouting port 2 and slip casting extension tube 15 be injected separately into inside and outside set
Cylinder, after filling sleeve grouting material in sleeve, sleeve grouting material is overflowed from the grout outlet 3 and pulp extension tube 14 of corresponding sleeve,
Then grout outlet and pulp are extended into duct occlusion, slip casting terminates.
Depth measuring ruler 16 10-30 minutes after slip casting, is inserted into grout outlet 3 or pulp extension tube by step 6 one by one
In 14, measurement probes into depth and registered depth A, if depth A is more than the corresponding grout outlet measured or pulp in step 2 and prolongs
The length of long tube should repeat step 2 immediately and carry out benefit slurry, and 10min reuses depth measuring ruler measurement and remembers again after mending slurry
Depth A is recorded, until the length that the depth A that 10min after slurry is measured is less than grout outlet or pulp extension tube is mended, but slip casting total time
2h is must not exceed, slip casting is completed.
Step 7 completes the construction of this connection structure after sleeve grouting material hardens and reaches design strength.
Step 8 tests to slip casting plumpness in sleeve after the hardening of sleeve grouting material.
The method of inspection is：Depth measuring ruler 16 is set to be inserted into grout outlet 3 or pulp extension tube 14 one by one, measurement probes into depth simultaneously
Registered depth B proves that slip casting is full in sleeve if depth B is less than the length of grout outlet or pulp extension tube, if deep
The length that B is more than grout outlet or pulp extension tube is spent, then slip casting plumpness needs subsequently to be located there are problem in sleeve
Reason.

It is characterized in that, construction procedure is as follows：
Step 1：According to lower layer's reinforcing bar（12）And top bars（11）Diameter determine reinforcing bar grouting branch sleeve diameter, wall
Then thick and length is molded in factory process；
Step 2：By design requirement by lower layer's reinforcing bar（12）And top bars（11）Respectively in lower layer's prefabricated components（10）The upper layer and
Prefabricated components（9）Middle processing is bound, then by one group of reinforcing bar grouting branch sleeve and outer barrel（1b）Corresponding extension tube
（14）Fixed to upper layer prefabricated components（9）At the position preset, pulp extension tube（14）It is straight at one with the direction of grout outlet
Line is installed obliquely, while recording grout outlet using linear measure longimetry steel ruler（3）With pulp extension tube（14）Length；
Step 3:Check it is errorless after, pour the concrete of prefabricated components and conserve to qualification；
Step 4:Prefabricated components are transported to construction site, by lower layer's prefabricated components（10）In lower layer's reinforcing bar（12）Top insert
Enter upper layer prefabricated components（9）In reinforcing bar grouting branch sleeve in, and sealed using rubber plug；
Step 5：Prepare sleeve grouting material（13）, from grouting port（2）With slip casting extension tube（15）Set inside and outside being injected separately into
Cylinder, after filling sleeve grouting material in sleeve, grout outlet of the sleeve grouting material from corresponding sleeve（3）With pulp extension tube（14）It overflows
Go out, grout outlet and pulp are then extended into duct occlusion, slip casting terminates；
Step 6：10-30 minutes after slip casting, by depth measuring ruler（16）It is inserted into grout outlet one by one（3）Or pulp extension tube
（14）In, measurement probes into depth and registered depth A, if depth A is more than the corresponding grout outlet or pulp measured in step 2
The length of extension tube should repeat step 2 immediately and carry out benefit slurry, mend 10min after slurry and reuse depth measuring ruler and measure and again
Registered depth A, until mend the length that the depth A that 10min after slurry is measured is less than grout outlet or pulp extension tube, but when slip casting is total
Between must not exceed 2h, slip casting is completed；
Step 7:After sleeve grouting material hardens and reaches design strength, the construction of this connection structure is completed；
Step 8：After the hardening of sleeve grouting material, test to slip casting plumpness in sleeve；
The method of inspection is：Make depth measuring ruler（16）It is inserted into grout outlet one by one（3）Or pulp extension tube（14）, measure and probe into depth
And registered depth B proves that slip casting is full in sleeve if depth B is less than the length of grout outlet or pulp extension tube, if
Depth B is more than the length of grout outlet or pulp extension tube, then slip casting plumpness needs subsequently to be located there are problem in sleeve
Reason.
