Assembling type concrete column base node structure and construction method thereof

Abstract

The invention discloses an assembling type concrete column base node structure and a construction method thereof. The assembling type concrete column base node structure comprises a reinforced concrete foundation and a prefabricated reinforced concrete column, wherein the part of the top surface of the reinforced concrete foundation, corresponding to the connection of the prefabricated reinforcedconcrete column, is provided with a rough surface; the parts in the reinforced concrete foundation, corresponding to vertical reinforcements in the prefabricated reinforced concrete column, are provided with foundation anchoring reinforcements; vertical grouting sleeves sheath the upper parts of the foundation anchoring reinforcements; the top parts of the grouting sleeves are level to the top part of the reinforced concrete foundation; a circle of externally-wrapping steel plates are arranged at the lower part of the prefabricated reinforced concrete column; exhausting holes and grouting holes are formed in the externally-wrapping steel plates; corresponding to the externally-wrapping steel plates in position, a top plate, cross partitioning plates, vertical partitioning plates, groutingpipes and exhausting pipes are also embedded in the prefabricated reinforced concrete column. The assembling type concrete column base node structure and the construction method disclosed by the invention have the beneficial effect that the technical problem of damage of the column base due to poor deformation capability and mechanical property of the column base node with the assembling type structure is solved.

Description

technical field [0001] The invention belongs to the field of prefabricated structural buildings, in particular to a prefabricated concrete column base node structure and a construction method thereof. Background technique [0002] At present, in the prefabricated frame structures commonly used at home and abroad, the column foot nodes are mainly connected by grouting sleeves. The column foot connected by the grouting sleeve bears a large force, and the longitudinal reinforcement in the column bears the largest force at the joint between the column foot and the foundation, and the remaining longitudinal reinforcement is relatively small due to the concrete wrapping, which leads to concentrated deformation of the longitudinal reinforcement at the seams. Under the rare earthquake load, the longitudinal reinforcement at the joint is easy to break due to excessive deformation, resulting in structural damage of the prefabricated building. At the same time, grouting sleeves gener...
