Connection structure of prefabricated assembly column and reinforced concrete foundation and construction method

Abstract

The invention relates to a connection structure of a prefabricated assembly column and a reinforced concrete foundation. The connection structure is characterized in that the bottom surface of the prefabricated assembly column is provided with a connection tenon, a foundation connection steel body, column side connection ribs and a column bottom reinforcement plate, the top part of the prefabricated assembly column is provided with built-in connection bolts, connecting steps, column inner connecting reinforcement bars and connecting anchor bars, and an interface grid layer is arranged on the outer surface of the prefabricated assembly column; the upper surface of the reinforced concrete foundation is provided with a column bottom connection groove, a reinforcing angle steel arrangement groove and a column side connection rib insertion groove, the interior of the reinforced concrete foundation is provided with a foundation inner anchor plate, foundation connection ribs and post-glue-injection holes; a column bottom shock absorber layer and reinforcing angle steel are arranged at the junction of the reinforced concrete foundation and the prefabricated assembly column; a limiting hoopplate is arranged outside the reinforcing angle steel; the foundation connection bars are connected with the column inner connecting reinforcement bars through a steel bar connection section, and a closed strip is arranged at the intersection of a post-poured concrete layer and the prefabricated assembly column. The connection strength of the structure can be enhanced, and the shock resistance ofthe structure can be improved. The invention also discloses a construction method of the connection structure of the prefabricated assembly column and the reinforced concrete foundation.

Description

technical field [0001] The invention relates to a connection structure between a prefabricated column and a reinforced concrete foundation and a construction method that can effectively improve the stress behavior and seismic performance of the connection structure between the prefabricated column and reinforced concrete, enhance structural integrity, and facilitate on-site construction organization, and belongs to the field of construction engineering . Background technique [0002] In recent years, with the rapid development of my country's economy, the industrialization of construction has been continuously developed. The prefabricated concrete structure is an important structure to realize the development mode of industrialization of construction. Its advantages of economy, convenience and environmental protection have been highly praised at home and abroad. big concern. [0003] The stress of the connection nodes of prefabricated building components is relatively compli...

AI Technical Summary

Problems solved by technology

This connection method is easy to operate and convenient to construct, but the overall stability is poor, the seismic performance is not strong, and the impact resistance, shear resistance and pullout resistance are poor.

[0006] To sum up, some existing connection methods between prefabricated columns and foundation nodes have achieved good results under suitable working conditions, but they are not effective in improving the efficiency of on-site construction, improving the stress behavior of nodes, and improving the quality of on-site construction. room for improvement
