Benefits of technology

[0010]Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide to a rigid connection structure between an upper PC column and a lower PC column and a rigid connection structure of a PC beam using the same that impro

Problems solved by technology

The method for simply mounting the PC beam onto the PC column is one of methods widely used currently, which is capable of somewhat reducing the construction period, but since a column and beam connection in the method is made through simple jointing, a moment cannot be transferred in this method when a lateral force like an earthquake is applied.
Accordingly, lateral force reinforcing means like shear walls, braces and so on should be additionally located, thereby failing to provide the advantages of the PC method planned for reducing the construction period and unavoidably increasing construction cost and period.
When the PC beam is simply mounted on the PC column, further, the escape of the column-beam connection may be generated to cause safety accidents.
Accordingly, the structural instability in the column-beam connect

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to a rigid connection structure between an upper precast concrete column and a lower precast concrete column and a rigid connection structure of a precast concrete beam using the same that improve a column-column connection and a column-beam connection, while performing moment connection, that is, rigid connection, in a dry construction method, thereby enhancing the constructability thereof to allow the rigid connection to be achieved only by the connection of reinforcing bars before concrete is cast on the connections.Background of the Related Art[0002]So as to ensure good constructability and reduce a construction period, recently, a precast concrete (hereinafter, referred to as “PC”) method has been increasingly adopted.[0003]Examples of the conventional PC method include a method for simply mounting a PC beam onto a PC column and a method for unitarily casting a PC column and a PC beam.[0004]The...
