Embodiment 1
[0055] Such as figure 1 , figure 2 , image 3 As shown, an anti-seismic assembled self-locking rolling semi-grouting sleeve, including a sleeve 5, a steel pipe transition section 7, and a self-locking steel skeleton 4;
[0056] The sleeve 5 is made of seamless steel pipe, and the sleeve 5 includes a non-grouting connection section 51 and a grouting connection section 52; the grouting connection section 52 is processed by rolling to form grooves 523 on the outer wall and convex ribs 522 on the inner wall. Both ends of the grouting connection section 52 are provided with a grouting hole 521 and a vent hole 511 respectively, and the vent hole 511 is close to the non-grouting connection section 51. In order to ensure sufficient grouting, the present embodiment can also design the diameter of the vent hole 511 The diameter is smaller than the diameter of the grouting hole 521, so that the grouting amount is greater than the grouting amount, thereby ensuring that the grouting in ...
Embodiment 2
[0063] A method for processing an anti-seismic assembled self-locking rolling semi-grouting sleeve 5: comprising the following steps:
[0064] Step 1) Processing of sleeve 5
[0065] Select a seamless steel pipe with an appropriate wall thickness, generally with a wall thickness of 2.0-5.5mm, and cut an appropriate length to make a sleeve 5. The sleeve 5 includes a non-grouting connection section 51 and a grouting connection section 52; the inner wall of the non-grouting connection section 51 The internal thread is processed, and multiple grooves 523 are provided on the surface of the grouting connection section 52 , and multiple convex ribs 522 are provided on the inner surface, and the circumferential reinforcing ribs 2 are fixed in the grooves 523 . In this embodiment, the preparation method of the circumferential reinforcement rib 2, the groove 523, and the convex rib 522 is as follows: use a steel bar ring to make a C-shape sleeve on the surface of the grouting connection...
Embodiment 3
[0074] A method for processing a prefabricated concrete member, comprising the following steps:
[0075] Step 1. Binding of reinforced skeleton of prefabricated concrete members
[0076] One end of the first steel bar 11 to be connected is bound and fixed with other steel bars to form a reinforced skeleton of the fabricated concrete member. The other end of the first steel bar to be connected is inserted into the rolling section 71 of the steel pipe transition section 7, and the steel pipe transition section 7 is realized by rolling machinery. The connection with the first steel bar 11 to be connected, so that the self-locking semi-grouting sleeve is pre-installed in the reinforced skeleton of the prefabricated concrete member;
[0077] Step 2. Pouring of prefabricated concrete elements
[0078] Connect the plastic pipe 8 to the grouting hole 521 and the vent hole 511 on the side wall of the sleeve 5 and lead it out of the building formwork, then the concrete placing machine ...
