Problems solved by technology

[0003] In addition to the traditional grouting sleeve, there are many installation procedures, the grouting is not easy to control, the sleeve and the steel bar are not easy to connect, the insertion is difficult, and the installation efficiency is extremely low.
Although the principle of the traditional grouting sleeve is feasible, the grouting quality cannot be guaranteed because the grouting quality is easily affected by the level, quality, sense of responsibility of the grouting workers, the quality of the grouting material, and external conditions such as weather. The most terrible thing is the grouting effect Or the quality cannot be effectively detected
The consequence is that designers either dare not use the grouting sleeve connection technology, or use the grouting sleeve connection technology cautiously with more safety reserves, and it is difficult or impossible to bypass the sleeve connection technology for prefabricated buildings, so it restricts The development of prefabricated buildings
Also, due to the high cost of traditional sleeve connection, everyone deliberately uses less parts and components that require grouting sleeve connection, which seriously affects the improvement of the assembly rate of prefabricated buildings

Embodiment 1

[0039] A kind of preset grouting material sleeve for construction, such as figure 1 As shown, it includes a sleeve body 3, the upper part of the sleeve body 3 has a threaded connection hole 2 for threaded connection with the upper steel bar 1, the sleeve body 3 has a slurry cavity, and the slurry cavity is provided with multiple A slurry bag 4, the slurry bag 4 is packaged in the slurry chamber by a sealed tin foil 5, in order to ensure that the sealed tin foil 5 is damaged during transportation, a protective rubber plug 6 is installed at the bottom of the sleeve body 3, and the preferred rubber plug is Perforated rubber stopper.

[0040] The slurry capsule 4 includes at least two types of slurry capsules. The slurry in each capsule does not coagulate, but at least two slurry capsules are mixed together with the slurry that is crushed and ruptured by the lower steel bars to form a coagulable capsule. After various kinds of slurry are mixed together and solidified, the upper s...

Embodiment 2

[0046] A kind of preset grouting material sleeve for construction, such as image 3 As shown, the sleeve body 3 is included, the bottom of the sleeve body 3 has a threaded connection hole 2 for threaded connection with the lower steel bar 7, the sleeve body 3 has a slurry cavity, and the slurry cavity is provided with multiple A slurry bag 4, the slurry bag 4 is packaged in the slurry cavity by a sealed tin foil 5.

Abstract

The invention discloses a preset slurry grouting sleeve for a building, a prefabricated member connecting structure and a prefabricated member connecting method. The preset slurry grouting sleeve for the building comprises a sleeve body, wherein a screw thread connection hole is formed in one end of the sleeve body, the sleeve body is connected with a first reinforcing steel bar in a threaded manner through the screw thread connection hole, a slurry chamber is arranged at the other end of the sleeve body, and extends towards the inside of the sleeve body, a plurality of slurry bags are arranged in the slurry chamber in a sealed manner through sealing sheets, and slurries in the respective slurry bags are mixed with one other uniformly and coagulate to fixedly connect the sleeve body with a second reinforcing steel bar when the plurality of slurry bags are squeezed to crack by a second reinforcing steel bar. The preset slurry grouting sleeve for the building disclosed by the invention has the advantages of increased construction efficiency, reduced cost and capability of producing enormous economic benefits.

Description

technical field [0001] The invention relates to a pre-installed grouting material sleeve for construction, a prefabricated part connection structure and a connection method, and is especially suitable for the field of prefabricated buildings. Background technique [0002] At present, the upper steel bar and the lower steel bar of the building industrialization prefabricated components are connected by sleeves, and the sleeves are installed in the prefabricated components, and have been connected with the sleeve screws when the upper steel bars are prefabricated. The lower reinforcement is inserted into the sleeve, and then grouted through the reserved holes to connect the upper reinforcement and the lower reinforcement through the sleeve. [0003] In addition to the traditional grouting sleeve, there are many installation procedures, the grouting is not easy to control, the sleeve and the steel bar are not easy to connect, the insertion is difficult, and the installation eff...
