[0003] Publication number CN218149266U discloses a reinforcement fixing structure within a building beam, comprising upper longitudinal reinforcement, lower longitudinal reinforcement, stirrups, beam side structural reinforcement, tie bars, and mounting plates. By installing a plurality of mounting plates on the upper longitudinal reinforcement, onto which are mounted a plurality of longitudinally evenly spaced beam side structural reinforcements, this prevents the structural reinforcements from tilting downward due to gravity during the fixing process, ensuring that the height of each section of the beam side structural reinforcement is consistent. Furthermore, the spacing between two adjacent beam side structural reinforcements is fixed, ensuring precise positioning of the beam side structural reinforcements.
