Abstract
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...
Examples
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.
[0047] 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 crushed and broken by the upper steel bar to form a condensable capsule. After various kinds of slurry are mixed together and solidified, the upper steel bar and the lower steel bar are fixedly connected together.
[0048] The slurry bladder 4 is preferably a double slurry bladder.
[0049] A prefabricated connection structure, such as Figure 4 As shown, it includes an upp...
