Embodiment 1
[0023] Example 1: as figure 1 , 2 As shown, a prefabricated concrete is connected to prefabricated parts with vertical longitudinal reinforcement, including prefabricated upper truncated column 1, prefabricated lower truncated column 2, and prefabricated composite beam 5. The prefabricated composite beam 5 is divided into two sections, and the two sections are prefabricated The joint area 4 is formed between the composite beam 5 and the prefabricated upper sectional column 1 and the prefabricated lower sectional column 2, and the two sections of the prefabricated composite beam 5 are provided with horizontal reserved longitudinal reinforcement 5.1 running through its length direction and protruding from its two ends , the horizontal reserved longitudinal reinforcement 5.1 between the two sections of prefabricated composite beams is connected through the steel connection sleeve 6, and the connection sleeve 6 can be selected according to the actual situation during the connectio...
Embodiment 2
[0024] Embodiment 2: When carrying out construction work, after splicing the prefabricated lower section column 2 and the two sections of prefabricated composite beams 5, a spliced node area 4 is formed, and the spliced node 4 area is filled with concrete pouring; The semi-grouting steel bar joint 3 used for steel bar connection is screwed on several reserved longitudinal reinforcements 2.1 protruding from the upper end surface of the prefabricated lower column 2; the prefabricated upper column 1 is hoisted directly above the prefabricated lower column 2, and then Grouting is carried out in the connecting sleeve 3.1 of the semi-grouting steel bar joint 3 for vertical steel bar connection. After the grouting is full, several upper reserved longitudinal bars 1.1 protruding from the lower end surface of the prefabricated upper section column 1 are inserted into the connecting sleeve 3.1, and the upper prefabricated When the longitudinal reinforcement 1.1 is inserted into the c...
