Steel plate interface connecting structure and method for reinforced concrete beam and column

Abstract

The invention discloses a steel plate interface connecting structure and method for a reinforced concrete beam and column. The connection of a prefabricated column and a prefabricated beam is achievedthrough an auxiliary interface steel sleeve and a steel beam shoe. The interface steel sleeve is formed into a whole by connecting two interface steel plates, two groups of shear keys and two groupsof anchor tie bars, and the interface steel sleeve is embedded on the column; the steel beam shoe is a steel sleeve with openings in the two ends, wherein the steel sleeve is defined by two side plates, a bottom plate and a top plate. After assembly, the prefabricated beam is sleeved with the steel beam shoe. The interface steel sleeve and the steel beam shoe are connected through welding. Duringconnection, the interface steel sleeve and the column are prefabricated into the whole, then the bottom plate and the two side plates of the steel beam shoe are welded to the interface steel plate toform a notch, and the notch and the column are connected into the whole; the beam is seated in the notch of the steel beam shoe, and then the top plate of the steel beam shoe is welded to the interface steel plate and the side plates to form an enclosure; plug welding holes are welded, screws are screwed into the screw holes, and then the assembling connection is completed. The connecting structure provided by the invention has the advantages that the beam and the column are simplified, and the performance is excellent.

Description

technical field [0001] The invention relates to a steel plate interface connection structure and connection method between reinforced concrete beams and columns, and is an assembled structure technology in the field of construction engineering. Background technique [0002] In recent years, with the continuous improvement of people's requirements for living conditions and living environment, the construction industry has developed rapidly. However, the development of the construction industry has caused serious resource consumption and environmental pollution, forcing people to seek a new way out of the construction industry. At present, the industrialization of buildings characterized by prefabricated buildings is one of the key ways to achieve low-carbon and sustainable development in the construction industry. [0003] In prefabricated buildings, the connection of structural components has a crucial influence on the efficiency of prefabricated and assembled construction ...

Problems solved by technology

However, there are still some deficiencies in the connection method of this structure, mainly including: 1. In order to facilitate the tensioning and anchoring operations at both ends of the post-tensioned prestressed beams, the assembled prestressed beams are generally multi-span frame beams that run through the entire horizontal or vertical Then stretch out the side columns to both ends and then carry out tensioning and anchoring operations, which brings great difficulties to the beam penetration, and also leads to excessive loss of tensioning friction prestress; 2. Another kind of existing prestressed assembly steel In the concrete frame structure, in order to facilitate beam penetration, the section of the beam section in the local area on both sides of the beam-column joint is widened to form a local end face, and then the beam is threaded in this range and tensioned and anchored on the local end face to form a local prestressed assembly connection, but this causes the frame beams to be deformed, which brings troubles to its prefabrication and future use
