Abstract

The invention discloses a prefabricated concrete structure beam column connecting joint, a connecting method and a repairing method. The prefabricated concrete structure beam column connecting joint comprises a joint plate, prefabricated beams connected to the left side and the right side of the joint plate, an upper-layer prefabricated column connected to the upper end of the joint plate and a lower-layer prefabricated column connected to the lower end of the joint plate; connecting blocks and groove-shaped joints are arranged between the joint plate and the prefabricated beams; and the joint plate, the connecting blocks and the groove-shaped joints are connected into a whole through main steel stranded wires. The prefabricated concrete structure beam column connecting joint has the characteristic of self-resetting, residual deformation after an earthquake is small, and it is guaranteed that the building use function of the structure can be rapidly recovered after the earthquake. Meanwhile, the damage to the structure is limited in the connecting blocks which can be easily replaced or repaired, so that repairing after the earthquake is quick and convenient. In addition, the whole structure is composed of detachable parts, and the sustainable development performance of a building can be improved by conveniently disassembling and recycling prefabricated parts.

Description

technical field [0001] The invention is applicable to the technical field of civil engineering, and relates to a beam-column connection node and method of a prefabricated concrete structure. Background technique [0002] Prefabricated concrete frame structure is one of the most common and widely used prefabricated structural systems. It has the advantages of reliable function, high durability, easy repair, rapid construction, reasonable cost and convenient mass production. [0003] In areas where earthquakes are rare, precast concrete structures are gradually replacing traditional cast-in-place concrete systems. [0004] However, the existing precast concrete structures have the disadvantages of poor integrity and weak seismic performance, which limit their use in earthquake-prone areas. In precast concrete structures, the connection mode of columns, beams and floors, especially the connection mode of beam-column joints is the core factor affecting the seismic performance o...
