A precast concrete beam with high-strength joints

Abstract

The invention relates to the technical field of building nodes and discloses a precast concrete beam with high-strength connecting nodes. The precast concrete beam comprises a concrete longitudinal beam, wherein the concrete longitudinal beam is internal provided with erection ribs, transverse stress ribs are arranged in the concrete longitudinal beam, longitudinal stress ribs are arranged in theconcrete longitudinal beam, and the erection ribs, the transverse stress ribs and the longitudinal stress ribs are connected in a staggered way. According to the precast concrete beam with high-strength connecting nodes, the concrete longitudinal beam can bear outside pull forces, shear forces and bending forces under the joint effects of the erection ribs, the transverse stress ribs and the longitudinal stress ribs so that the concrete longitudinal beam can bear the effect of a force of a concrete transverse beam, the frictional forces between arc-shaped clamp-connecting grooves and arc-shaped clamp-connecting plates are increased under the joint effects of upper clamping teeth and lower clamping teeth, and thus the arc-shaped clamp-connecting grooves and the arc-shaped clamp-connecting plates are difficult to separate under external forces.

Description

technical field [0001] The invention relates to the technical field of building nodes, in particular to a prefabricated concrete beam with high-strength connecting nodes. Background technique [0002] Reinforced concrete beams are beams made of reinforced concrete materials. Reinforced concrete beams can be made as independent beams, beam-slab floors integrally formed with reinforced concrete slabs, or single-layer or multi-layer integrally formed with reinforced concrete columns. Frames and reinforced concrete beams have various forms, and are the most basic load-bearing components in engineering structures such as housing construction and bridge construction, and have a wide range of applications. [0003] There is a kind of concrete beam that is prefabricated beam. Prefabricated beam is a kind of concrete beam component that is molded, mixed and poured at the concrete component factory or construction site. After the strength reaches the design requirements, it is transpo...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a prefabricated concrete beam with high-strength connection nodes, which has the advantages of high connection strength and high load-bearing strength, and will not be unable to support the concrete beam due to the settlement of the concrete longitudinal beam. The simple structure of the connection node of the beam leads to the problem that the bearing capacity is not good enough
