Prefabricated concrete ring beam based on PBL connection

Abstract

The invention discloses a prefabricated concrete ring beam based on PBL connection. The ring beam comprises a longitudinal ring beam, a transverse ring beam, a longitudinal ring beam pre-embedded part, a ring beam-upper shear wall pre-embedded part A, a ring beam-lower shear wall pre-embedded part A, a ring beam bracket A, a transverse ring beam pre-embedded part, a ring beam-upper shear wall pre-embedded part B, a ring beam-lower shear wall pre-embedded part B, and a ring beam bracket B. The prefabricated concrete ring beam based on PBL connection has the beneficial effects that PBL shear transfer plates are pre-buried in the ring beams, so that the stress performance is good; the ring beams are factory-like prefabricated parts and can be directly installed on a construction site, so that the construction efficiency is improved; dry-type connecting joints are adopted, so that on-site wet operation is completely abandoned, installation is easy and fast, the advantages of saving resources, protecting the environment and reducing pollution of a prefabricated building technology are played to the maximum extent; and concrete materials are adopted, so that the durability is good, the installation is convenient, turnover can be achieved, and the ring beam is suitable for projects which are long in construction period and high in requirement for durability of temporary engineering houses.

Description

technical field [0001] The invention relates to a ring beam, in particular to a prefabricated concrete ring beam based on PBL connection, and belongs to the technical field of construction engineering applications. Background technique [0002] The application of prefabricated technology for middle and low-rise buildings is mainly reflected in temporary buildings, light steel villas, etc. For prefabricated buildings with concrete structures, beam structures such as ring beams are usually constructed by cast-in-place construction, which seriously affects the construction speed and easily causes environmental damage and resources. Waste, affecting the development of prefabricated structures. Most of the beam connection positions adopt wet connection, which cannot maximize the advantages of prefabricated building technology to save resources, protect the environment and reduce pollution. Based on this, the present application proposes a precast concrete ring beam based on PBL c...
