When forming, comprises
The beam head anti-shearing force transfer barrel is characterized by comprising an oblique cutting line (6-5) and a middle transverse cutting line (6-6), wherein the oblique cutting line (6-5) and the middle transverse cutting line (6-6) are cut along the lateral surface of the beam head anti-shearing force transfer barrel (2) to form a first triangular bending part (6-7) on the left side and a second trapezoidal bending part (6-8) on the upper side and the lower side, and the first triangular bending part (6-7) and the second trapezoidal bending part (6-8) are bent inwards by 90 degrees along a vertical bending line (6-11) and a transverse bending line (6-4) respectively to form a beam head anchoring communication hole (6).
5. The socket-and-spigot precast concrete beam of claim 2, wherein: when the cutting line is X-shaped, the cutting line comprises an X-shaped diagonal oblique cutting line (6-9), the side surface of the beam head shearing-resistant force transmission barrel (2) after the diagonal oblique cutting line (6-9) cuts forms an upper triangular bending part II (6-10), a lower triangular bending part II (6-10), a left triangular bending part II (10), a right triangular bending part II (10), a left triangular bending part II (6-10) and a right triangular bending part II (6-10) are bent inwards for 90 degrees respectively along a vertical bending line (6-11) and a transverse bending line (6-4), and a beam head anchoring communication hole (6) is formed.
6. The socket-and-spigot precast concrete beam of claim 1, wherein: the width of the beam head anchoring communication holes (6) is not more than one third of the width of the side surfaces of the beam head shearing-resistant force transmission barrel (2), and the beam head anchoring communication holes (6) on the adjacent two side surfaces are arranged in a staggered mode.
7. The socket-and-spigot precast concrete beam of claim 1, wherein: the beam head shearing-resistant force-transmitting barrel (2) is made of steel plates and section steel materials, the section size and the material thickness of the beam head shearing-resistant force-transmitting barrel are determined by calculation according to the section size of a column and the borne internal force, and the section is in a shape like a Chinese character 'kou' or a shape like a Chinese character 'tian' or a shape like a Chinese character 'jing'.
