[0016] Workflow: This utility model provides a salt spray resistant prefabricated concrete beam-column connection component.

The main structure also facilitates integrated grouting of the beam-column connection node 1 with a crossbeam, improving the grouting effect of the beam-column connection node 1. First, the salt spray resistant steel bar kit 6 is prefabricated and grouted. One end of the inner node steel bar 602 and one end of the outer node steel bar 603 are attached to the central partition of the casing 601. A first rubber ring 606 is inserted into the outer side of the first semi-ring 605. Structural adhesive is sprayed onto the first sponge layer 607, and the two symmetrically distributed first... Half-ring 605 is inserted and placed between the inside of one end of the casing 601 and the outside of the inner node steel bar 602. Structural adhesive is used to fill the gap between the inner node steel bar 602 and the first sponge layer 607. A second rubber ring 609 is inserted and placed on the outside of the second half-ring 608. Structural adhesive is sprayed towards the second sponge layer 610. Two symmetrically distributed second half-rings 608 are inserted and placed between the inside of the other end of the casing 601 and the outside of the outer node steel bar 603. Structural adhesive is used to fill the gap between the outer node steel bar 603 and the second sponge layer 610. After the structural adhesive has cured, concrete grout is injected into the interior through the grouting pipe at one end of the casing 601 to provide internal reinforcement. Salt spray grouting protection treatment is applied to the connection positions of the node reinforcement 602 and the outer node reinforcement 603. After the internal concrete grout has cured, a grouting cap 604 is threaded onto the inner wall of the grouting pipe at one end of the sleeve 601. Then, the salt spray resistant reinforcement kit 6 is combined with the grouting beam shell 4. A third rubber ring 612 is inserted into the outer side of the third semi-ring 611. Structural adhesive is sprayed onto the third sponge layer 613. Two symmetrically distributed third semi-rings 611 are inserted between the inner end of the grouting beam shell 4 and the outer side of the outer node reinforcement 603. The structural adhesive is used to fill the gap between the outer node reinforcement 603 and the third sponge layer 613. After the structural adhesive has cured, the beam-column connection node is completed. 1. Annular sealing rings 3 are placed inside the four sides. The connection plate 5 and the four sides of the beam-column connection node 1 are threaded together by bolts. The other end of the inner node steel bar 602 is placed inside the beam-column connection node 1. The grouting beam shell 4 is placed tightly against the annular sealing ring 3. The above-mentioned annular sealing ring 3, first rubber ring 606, second rubber ring 609, third rubber ring 612 and structural adhesive all play a role in preventing leakage of concrete grout. The beam-column connection node 1, grouting beam shell 4 and salt spray resistant steel bar kit 6 are grouted together through the grouting port 2 in a cross beam manner. After grouting is completed, a salt spray resistant coating is sprayed on the surface of the main structure to enhance the protective effect.
