Gap avoids reinforcing bar from occurring loosening in filling process, tilt.Bonding adjacent reinforced concrete structure can also be played after aging simultaneously
The effect of part.
Referring to Fig. 3 and Fig. 4, it is described in detail below with the construction procedure of the spliced grout sleeve:
(1) prefabrication produces: when production prefabricated components, by the embedded bar and first sleeve in the first prefabricated components 13
2 first connecting pins 16 are detachably connected, and install the first sealing ring 18 in the first connecting pin 16, and then whole be put into mold is poured
It builds concrete production and goes out the first prefabricated components 13；Same mode is by the embedded bar and second sleeve in the second prefabricated components 12
1 second connection end 10 is detachably connected, while installing the second sealing ring 9, then whole to be put into casting concrete life in mold
Produce the second prefabricated components 12.
(2) connection 3 one sections of grafting of reinforcing bar now live Primary Location: are mounted on to the first prefabricated structure for offering grouting mouth 8
In first sleeve 2 in part 13.
(3) be in the milk preparation: determine grouting mouth 8 and thick liquid discharge mouth 7 it is unobstructed, check whether pollution, moisten prefabricated components and
Grouting material contact surface, smears epoxy resin mortar contact surface, and hoisting prefabricated component adjusts verticality.
(4) dock prefabricated components: the second prefabricated components 12 of lifting dock the first prefabricated components 13, keep connection reinforcing bar 3 another
Section insertion second sleeve 1, guarantees that first sleeve 2 and second sleeve 1 are spliced accurately, forms complete grout sleeve.
(5) mixing grouting material 14: in strict accordance with proportions grouting material 14, after mixing evenly by proportioned grouting material 14
Grouting equipment is poured into, guarantees the slump of grouting material 14.
(6) it is in the milk: the high-strength grout 14 mixed being imported into grouting pump, starts grouting pump, to the outflow of grouting pump mouth
When grouting material 14 is linear, using grouting method from bottom to top, grout pipe is inserted into the grouting mouth 8 on the first prefabricated components 13, from
Sleeve cavity 11 of the mouth 8 into grout sleeve of being in the milk injects high-strength grout 14, until overflowing grouting material 14 immediately from thick liquid discharge mouth 7
Thick liquid discharge mouth 7 is blocked, quickly extracts grout pipe plugging grouting mouth 8 out when then grouting material 14 overflows grouting material 14 from grouting mouth 8, at this time
High-strength grout 14, other grouting mouths 8 successively same grouting of the first prefabricated components 13 are filled with inside grout sleeve.
(7) after the completion of grout sleeve cementing operations, using high-strength concrete to the first prefabricated components 13 and the second prefabricated structure
12 junction of part is smoothed out, i.e. the connection of completion assembled in situ formula component node.
Embodiment 2
The present embodiment 2 provides a kind of building prefabricated components, including load main body, sliceable grout sleeve, sliceable filling
The embedded bar of one end and load main body for starching sleeve is detachably connected, and the other end of sliceable grout sleeve is open end, can
Splice grout sleeve and is equipped with slurry mouth.Load main body can be shear wall, can also be prefabricated post.
In construction projects, shear wall is primarily subjected to horizontal loading caused by wind load or geological process and vertical load,
Prevent structure shear from destroying, so shear wall is particularly important in earthquake-prone region and other regions.Top and the bottom prefabricated components can
To be shear wall, referring to Fig. 3 and Fig. 4, spliced grout sleeve are used for precast shear wall component, due to that can will connect reinforcing bar 3
Individually transport storage is separated with precast shear wall, when assembly passes through first sleeve 2 again and second sleeve 1 carries out splicing assembling, institute
To simplify the transport and storage of precast shear wall component well, avoid shear wall in the handling process because reinforcing bar is excessively too long
Lead to member impacts deformed damaged, also avoid the exposed outdoor of reinforcing bar, the not contaminated corrosion of reinforcing bar can be effectively protected.And pass through
Spliced grout sleeve can effectively improve construction efficiency and building structure overall performance, simplify construction technology, be also suitble to right
Construction environment requires high and earthquake to take place frequently area application.
Above-mentioned sliceable grout sleeve is applicable not only to shear wall, the connection being also applied between prefabricated post, referring to Fig. 5,
Spliced grout sleeve is used for prefabricated post, solves during transport storage and connection prefabricated post, because of prefabricated components
The problem of security risk existing for the too long excessive caused construction personnel of middle reinforcing bar, working environment and the operation of worker can be improved
Risk, the influence to periphery traffic and environment is smaller, and can reduce prefabricated post in the construction time because transporting and storing improper institute
Caused by loss, improve construction efficiency.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode.Even if to the present invention, various changes can be made, if these variations belong to the model of the claims in the present invention and its equivalent technologies
Within enclosing, then still fall within the protection scope of the present invention.
