Description

Technical Field

[0001] This utility model relates to the field of prestressed beam technology, specifically a prestressed beam for green and energy-saving buildings. Background Technology

[0002] Prestressed concrete structures: To avoid premature cracking in reinforced concrete structures, high-strength steel bars and high-strength concrete are fully utilized. In other words, prestress is generated in the structural members before they are subjected to loads to reduce or offset the tensile stress in the concrete caused by the loads, so that the tensile stress in the structural members is not large, or even in a state of compression.

[0003] Prestressed concrete is mainly used in: structures requiring a high level of crack control; large-span or high-stress components; and components requiring high stiffness and deformation control.

[0004] Currently, prestressed beams used in green and energy-saving buildings are typically used to support roads or bridges. During installation, the beams are connected to the supporting columns for fixation. The beams are moved using cranes, and the installation process requires precise alignment between the beams and the supporting columns. This necessitates repeated repositioning, which affects installation efficiency and presents a challenge in achieving accurate alignment. Furthermore, during use, the connection between the beams and supporting columns is mostly achieved through the insertion and fixing of reinforcing bars. However, with continuous stress on the beams, these reinforcing bars can cause wear at the connection points, leading to beam swaying, safety hazards, and poor stability of the beam connection structure.
