Prefabricated prestressed concrete frame structure connection joint construction method and joint
The invention discloses a prefabricated prestressed concrete frame structure connection joint construction method and a joint, and relates to the technical field of civil engineering, the prefabricated prestressed concrete frame structure connection joint comprises a prestressed prefabricated beam and a cast-in-place column, the bottom of the prestressed prefabricated beam is provided with a prefabricated beam bottom longitudinal bar, and one end of the prestressed prefabricated beam is provided with a key groove; the cast-in-place column and the key groove are combined to form a post-pouring section, a cast-in-place layer is arranged on the upper portion of the prestressed precast beam and the upper portion of the post-pouring section, and reinforcing pieces are arranged at the joint of the cast-in-place column and the top end of the cast-in-place layer and the right-angle joint of the cast-in-place column and the bottom end of the post-pouring section. The beam-column joint has the beneficial effects that the bottom longitudinal bars of the frame beam of the beam-column joint do not need to stretch into the column and are lapped through the U-shaped steel bars, when the prefabricated beam is installed on site, only the U-shaped steel bars need to be flexibly adjusted in the horizontal direction, the site construction difficulty can be obviously reduced, the construction efficiency is improved, the frame beam bottom bars do not need to be lifted up at the end positions, and the construction cost is reduced. The protective layer thickness of the end part of the frame beam can be ensured.
本发明公开了预制预应力混凝土框架结构连接节点施工方法及节点，涉及土木工程技术领域，包括预应力预制梁和现浇柱，所述预应力预制梁的底部设有预制梁梁底纵筋，所述预应力预制梁的一端设有键槽，所述现浇柱与键槽之间组合成后浇段，所述预应力预制梁和后浇段上部为现浇层，所述现浇柱与现浇层顶端的连接处以及现浇柱与后浇段底端的连接的直角处均设有加固件；本发明的有益效果是：梁柱节点框架梁的底部纵筋无需伸入柱内，用U型钢筋搭接，现场安装预制梁时，水平方向仅需灵活调节U型钢筋即可，可以明显降低现场的施工难度，提高施工效率，框架梁底筋在端部位置不需要上抬，可以保证框架梁端部的保护层厚度。
