Multidirectional rotation structure node for reinforced concrete column and construction method for multidirectional rotation structure node

Abstract

The invention discloses a multidirectional rotation structure node for a reinforced concrete column. The structure node consists of a core reinforced concrete column and an external reinforced concrete column, wherein the core reinforced concrete column and the external reinforced concrete column consist of concrete and a reinforcement framework which are sleeved with each other from inside to outside respectively. A construction method comprises the following steps of: preparing the core reinforced concrete column; embedding the core reinforced concrete column at a preset position, and welding a core column reinforcement framework at the periphery of a prefabricated pipe after the core reinforced concrete column is arranged in position; binding an external column reinforcement framework at the preset position; casting outer column concrete on site; mounting matched constraint materials and filling materials; and binding an upper member of the reinforced concrete column, and erecting a mold to cast the concrete so as to form the integral multidirectional rotation structure node of the reinforced concrete column. The multidirectional rotation structure node has the characteristics of saving manufacturing cost, along with definite design concepts and the like, is easy to construct, is safe and reliable, is durable in use, brings great benefits to the development of economy and society in China, and has a wide application prospect.

Description

technical field [0001] The invention relates to a structural node in the technical field of civil engineering and combined structures, in particular to a reinforced concrete column multi-directional rotating structural node and a construction method thereof. Background technique [0002] In recent years, the frequency of earthquakes has become higher and higher, and people's requirements for the earthquake resistance of buildings have also been higher. various. At present, there are many connection forms of structural nodes, such as slab-column structure, beam-column structure, etc. There are various connection methods, but some connection structures require a large number of additional components, which not only increases the capital investment of construction, but also The process is cumbersome and seriously affects the construction progress. Contents of the invention [0003] The present invention is aimed at the deficiencies of the prior art. Firstly, it provides a r...
