A connection method between a detachable assembled column and a ductile node of the foundation

Abstract

The invention discloses a detachable assembly type column and foundation ductile joint connection mode. A reinforced concrete column and a foundation, a steel structural connection piece with good ductility and hexagonal high-strength bolts are included. The steel structural connection piece is a hoop-shaped component which is manufactured by a steel mold, and vertical reinforcing ribs are weldedto the outer portion of the steel structural connection piece. The steel structural connection piece wraps a concrete block to form a square steel pipe concrete structure, holes corresponding to the positions of longitudinal ribs are formed in an upper end plate and a lower end plate of the square steel pipe concrete structure, and energy-consumable rubber threaded pipes are screwed into the holes; the tail ends of a column longitudinal rib and a column longitudinal rib in the foundation are subjected to tapping treatment, and are screwed into internal thread steel pipes and internal thread steel pipes with end plates arranged at the tail ends; and the three main components are connected through hexagonal screw rods. The joint connection mode is simple and convenient, dismounting is easy,industrialized production of the components can be achieved, the ductility and the energy consumption ability of the structure can be improved, the anti-shear ability of columns can be improved effectively as well, and the anti-seismic bearing ability of the columns is improved accordingly. The joint connection mode has the good disaster resistant ability, and the ideas of environmental protection, duration and sustainable development are reflected as well.

Description

technical field [0001] The invention relates to a connection method between a detachable assembly type column and a ductile node of a foundation, in particular to a connection method between a detachable assembly type reinforced concrete column and a foundation using a steel structure connector with good ductility, and belongs to the technical field of structural engineering. Background technique [0002] In many developed countries, prefabricated reinforced concrete buildings are the most important form of construction industrialization. It has the advantages of fast construction speed, short construction period, improved quality, energy saving, reduced consumption, and clean production. In recent years, my country has also vigorously promoted prefabricated buildings, and made corresponding requirements for the proportion of prefabricated buildings in new buildings. At the same time, with the advent of "urban intelligence" and "restorable functional cities", the industriali...

Problems solved by technology

The traditional prefabricated column and foundation connection methods mainly include plug-in connection, tenon connection and slurry-anchor connection, etc., but the process structure is relatively complicated, the construction is inconvenient, the construction difficulty makes the cost relatively high, and the quality is difficult to be guaranteed. Delivery is not immediate and cannot be replaced if damaged

In addition, in the construction of the connection between the prefabricated concrete column and the foundation, many manual processes cannot be completed by machinery, and these processes cannot be replaced by other methods

The processing method is also inconvenient for construction operations, labor-intensive, time-consuming, and the quality of the process has a great impact on the quality of the structure. The high-altitude operation of this process is easy to cause quality fluctuations
