Connecting structure and method for prefabricated reinforced concrete beam and prefabricated reinforced concrete column

Abstract

The invention discloses a connecting structure and method for a prefabricated reinforced concrete beam and a prefabricated reinforced concrete column. The connecting structure is mainly composed of the prefabricated reinforced concrete column, the prefabricated reinforced concrete beam, pre-buried anchor bars, straight thread standard sleeves, in-beam longitudinal bars, straight thread positive-negative wire different-diameter sleeves, adjustable connecting pieces and secondary grouting material connecting sections. The pre-buried anchor bars and the straight thread standard sleeves are connected and jointly pre-buried into the prefabricated reinforced concrete column. The in-beam longitudinal bars and the straight thread positive-negative wire different-diameter sleeves are connected andjointly pre-buried into the prefabricated reinforced concrete beam. The two ends of each adjustable connecting piece are connected with the straight thread standard sleeves and the straight thread positive-negative wire different-diameter sleeves correspondingly. A secondary grouting material is poured into connecting gaps between the prefabricated reinforced concrete column and the prefabricatedreinforced concrete beam which are connected through the adjustable connecting pieces to form the secondary grouting material connecting sections. According to the connecting structure and method, theon-site mounting process is simplified, the possible influence on exposed steel bars in the transporting and hoisting processes is avoided, and the construction quality is effectively ensured.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a connection structure and connection method of prefabricated reinforced concrete beams and columns. Background technique [0002] Prefabricated concrete structures are connected by prefabricated concrete components or components through steel bars, connectors or prestressing, and usually require on-site pouring of concrete to form an integral structure. It has the advantages of less constraints, short construction period, fast construction speed, labor saving and improvement of construction quality. [0003] In the context of the current era of promoting the theme of green environmental protection and pollution-free, prefabricated concrete structures are developing rapidly in my country. Building Evaluation Standards", JGJ1-2014 "Technical Regulations for Prefabricated Concrete Structures" and other series of standards and specifications regulate the design, construction ...
