Assembled framework beam-column joint adopting cover plate connection and construction method thereof

Abstract

The invention relates to an assembled reinforced-concrete framework beam-column joint adopting cover plate connection. The joint comprises a corbel of a precast column and a precast beam, wherein the end face of the corbel and the end face of the precast beam are respectively provided with a concave groove and a convex block which are matched with each other and are used for carrying out embedded fixing, steel plates are pre-buried in facades of the two sides of the connection part between the corbel and the precast beam, and steel cover plates are arranged at the outer sides of the steel plates pre-buried in facades of the two sides of the corbel and the precast beam and are fixedly welded to the steel plates pre-buried in the facades of the two sides of the corbel and the precast beam after the corbel and the precast beam are fixed in an embedding manner. A corresponding construction method comprises the steps of precasting, mounting and filling mortar in gaps. The joint and the corresponding construction method have the advantages that the strength of an assembled segment is enabled not to become a weak link of a structure under the action of a load, and the assembled segment has adequate earthquake resistance; the assembled segment is enabled to smoothly carry out internal force transmission and exert a connecting function; and the on-site assembling time is minimized, and the construction process is simple, convenient, fast and safe.

Description

technical field [0001] The invention relates to an assembled reinforced concrete frame beam-column node connected by a cover plate and a construction method. Background technique [0002] The prefabricated reinforced concrete frame structure has many advantages such as convenient construction, fast construction speed, short construction period, high production efficiency, high component quality assurance rate, and high degree of industrialization of production. Therefore, it has broad application prospects in the construction industry. The connection structure of the prefabricated reinforced concrete frame beam-column joints is the key link of the whole structure. If there are defects in the joint connection, it will cause structural cracks and other problems in the slightest, and it will affect the force transmission of the components, causing problems in bearing capacity and safety. , and even cause serious consequences such as structural disintegration and collapse.
