Preset slurry grouting sleeve for building, prefabricated member connecting structure and prefabricated member connecting method
A kind of grouting material and technology for construction, which is applied in the direction of building components, building reinforcements, building structures, etc. It can solve the problems that the grouting effect or quality cannot be effectively detected, the assembly rate of prefabricated buildings is affected, and the sleeve and the steel bar are not easy to connect. , to achieve the effect of overcoming the large dispersion of grouting quality, reducing the material of grouting pipe and grouting pipe, and stabilizing the quality of grout with precise ingredients

Example Embodiment
[0038] Example 1
[0039] A kind of preset grouting sleeve for construction, such as figure 1 As shown, a sleeve body 3 is included. The upper part of the sleeve body 3 is provided with a threaded connection hole 2 for threaded connection with the upper reinforcing steel bar 1, and the sleeve body 3 has a slurry cavity in the slurry cavity. A slurry capsule 4, the slurry capsule 4 is encapsulated in the slurry cavity by a sealing tin foil 5. In order to ensure that the sealing tin foil 5 is damaged during transportation, a protective rubber plug 6 is installed at the bottom of the sleeve body 3. The rubber plug is preferably Perforated rubber plug.
[0040] The slurry capsule 4 includes at least two slurry capsules, the slurry in each capsule does not coagulate, but the slurry after the at least two slurry capsules are squeezed and broken by the lower steel bar is mixed together to form a coagulable After the slurry is mixed and solidified, the upper and lower steel bars are fixed...

[0045] Example 2
[0046] A kind of preset grouting sleeve for construction, such as image 3 As shown, a sleeve body 3 is included. The lower part of the sleeve body 3 is provided with a threaded connection hole 2 for threaded connection with the lower steel bar 7, and the sleeve body 3 has a slurry cavity in the slurry cavity. A slurry pouch 4, the slurry pouch 4 is sealed in the slurry cavity by sealing tin foil 5.
[0047] The slurry capsule 4 includes at least two slurry capsules, the slurry in each capsule does not coagulate, but the slurry after the at least two slurry capsules are squeezed and broken by the upper steel bar is mixed together to form a coagulable After the slurry is mixed and solidified, the upper and lower steel bars are fixedly connected together.
[0048] The slurry bladder 4 is preferably a two-material slurry bladder.
[0049] A connection structure for prefabricated parts, such as Figure 4 As shown, it includes an upper prefabricated member 8 with upper...
