A prefabricated frame beam-column joint adopting vertical connection and its construction method

Abstract

The invention relates to an assembled reinforced-concrete framework beam-column joint adopting vertical bolt 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 respectively provided with a vertical corbel bolt hole and a vertical precast beam bolt hole; and the corbel is matched with the precast beam along the length direction of the precast beam in an embedded fixing manner, bolt cushion plates are arranged at the upper and lower sides of the corbel and the precast beam after the corbel and the precast beam are fixed in an embedding manner, and a bolt vertically penetrates through the bolt cushion plates, the corbel bolt hole and the precast beam bolt hole so as to carry out fixing. 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 smoothness of force transmission between the precast beam and the precast column is achieved, the joint is reliable in connection and simple in structure, the construction process is simplified, the on-site assembling time is saved, and the production efficiency can be effectively increased.

Description

technical field [0001] The invention relates to an assembled reinforced concrete frame beam-column node connected by vertical bolts and a construction method. Background technique [0002] With the acceleration of my country's construction industrialization process, the development of prefabricated structural systems is the only way to realize the green and low-carbon requirements of buildings and promote the structural adjustment and sustainable development of my country's construction industry. [0003] For the prefabricated reinforced concrete frame structure system, the beams, slabs, and columns of the main structure can be processed in the factory, and they only need to be spliced ​​together on site. Factory processing can objectively guarantee the quality of prefabricated structural components, while on-site splicing requires simpler construction procedures while ensuring structural quality. In the past, the connection reliability of beam-column joints of prefabricate...
