the first prefabricated part is provided with a plurality of first horizontally extending reinforcing steel bars which are distributed at intervals in the vertical direction, and one part of each first horizontally extending reinforcing steel bar is positioned in the corresponding first groove; the second prefabricated part is provided with a plurality of second horizontally extending reinforcing steel bars which are distributed at intervals in the vertical direction, and one part of each second horizontally extending reinforcing steel bar is positioned in the corresponding second groove; prefabricated component connected node still includes the spiral stirrup that vertical direction set up, the spiral stirrup twines simultaneously and is located in the cavity first level stretches out the reinforcing bar and the reinforcing bar is stretched out to the second level.
Adopt above-mentioned technical scheme, the spiral stirrup that utilizes vertical direction to set up stretches out the reinforcing bar with the level of first prefabricated component and second prefabricated component and connects, can strengthen the joint strength of first prefabricated component and second prefabricated component. Simultaneously, above-mentioned technical scheme can avoid the problem of the mutual overlap joint of the connecting reinforcement of prefabricated component tip among the prior art well, and the level in first prefabricated component and the second prefabricated component stretches out the reinforcing bar and can only be located corresponding first recess and second recess, need not be outstanding outside the recess, is favorable to the prefabricated component transportation.
Further, the first prefabricated component and the second prefabricated component are both prefabricated wall boards. The first prefabricated part and the second prefabricated part are connected in a straight line shape, in a T shape or in an L shape.
Furthermore, the parts of the first horizontally extending reinforcing steel bar and the second horizontally extending reinforcing steel bar in the cavity are arc-shaped.
Further, the cast-in-place portion is formed by casting concrete or cement-based grout in place.
The utility model discloses a prefabricated component connected node is favorable to full prefabricated component's improvement joint strength, simplifies the construction process, improves the efficiency of construction.
