Steel plate interface bolt connecting structure and method for reinforced concrete column and foundation

Abstract

The invention discloses a steel plate interface bolt connecting structure and method for a reinforced concrete column and foundation. The column and the foundation are connected through a steel plateassembly and an interlayer assembly. The steel plate assembly is composed of an interface steel plate, a shear key, a set of inner ring round holes and a set of outer ring round holes. The interlayerassembly is composed of a steel pipe hoop and micro-expansion fine aggregate concrete filled in the steel pipe hoop. The connecting method comprises the main steps: manufacturing the column and the steel plate assembly fixed to the bottom face of the column; manufacturing the foundation, and reserving an anchor bar and a foundation top dent; putting the steel pipe hoop in place and filling the steel pipe hoop with micro-expansion fine aggregate concrete; enabling the column and the steel plate assembly to be seated on the top surface of the micro-expansion fine aggregate concrete (without waiting for hardening), then the anchor bars penetrating through the circular holes in the outer ring of the interface steel plate are screwed down through nuts, and completing the connection of the column and a foundation. The connecting structure provided by the invention has the advantages that the column and the foundation are simplified, and the performance is excellent.

Description

technical field [0001] The invention relates to a steel plate interface bolt connection structure and connection method between a reinforced concrete column and a foundation, 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 ...

AI Technical Summary

Problems solved by technology

[0005] There is another dry connection method between the column and the foundation, which is to insert the prefabricated column into the cup of the prefabricated foundation, and then pour fine stone concrete into the gap of the cup. This connection method is very simple, but the connection node can only be Provides the effect of hinged connection, mainly used in structures such as single-layer bent frames, and cannot be applied to structures such as frame structures that need to provide the effect of consolidated connection
