LIU SHUNXIN

The invention discloses a precast beam with cable-stayed holes and a beam-column connecting structure of the precast beam. The precast beam with the cable-stayed holes comprises a precast beam body; a cable-stayed hole channel is formed from the end surface to the bottom surface of the precast beam body; the cable-stayed ducts are divided into two groups by taking the middle point of the precast beam body as the center and are symmetrically arranged at the two ends of the precast beam body. The beam column connecting structure comprises main body structural parts and the precast beam with the inclined pulling hole, wherein the precast beam is connected between the main body structural parts. One end of the prestressed tendon is fixed to the bottom face of the precast beam body, and the other end of the prestressed tendon penetrates through the main body structural part to be tensioned and fastened.

本发明公开了一种带斜拉孔的预制梁及其梁柱连接结构，带斜拉孔的预制梁包括：预制梁本体；预制梁本体的端面至其底面形成有斜拉孔道；斜拉孔道以预制梁本体的中点分为两组，对称布置在预制梁本体的两端。梁柱连接结构包括主体结构件，以及连接在主体结构件之间的上述的一种带斜拉孔的预制梁；斜拉孔道内穿射有预应力筋，预应力筋一端固定在预制梁本体的底面，另一端穿过主体结构件进行张拉紧固。
