Description

This paper describes a rigid connection structure between a steel column and concrete hybrid PC column and PC beam with joints placed thereon, and a rigid connection structure between the rigid connection structure and a rigid connection structure using the same}

The present invention relates to a steel-concrete hybrid PC column and a PC beam with a joining portion selectively installed using a PC beam mounting plate installed on a PC column to implement a moment bonding method by improving a joining portion between a column and a beam And a method of constructing a steel joint structure using the same.

In recent years, the use of PC (precast concrete) method has been increasing in order to secure workability and to save air.

Conventional PC method is mainly used for (1) simple installation of PC beams on PC columns, and (2) construction of PC columns and PC beams in one body.

(1) The method of simply mounting the PC beam on the PC column,

Although the air is somewhat reduced as one of the currently used methods, when a lateral force such as an earthquake acts, the column-to-beam connection is simply connected, and the moment can not be transmitted. Therefore, it is necessary to install a shear wall, brace, etc., which is a lateral reinforcement means, so that it is inevitable to increase the construction cost and air without meeting the merit of the PC method planned for air saving.

In addition, a PC mounted on a PC column may cause a safety accident due to the deviation of the column-to-beam connection. Therefore, the use of high - rise structures is limited due to the possibility of structural instability in column - beam connections.

The above-mentioned (2) method of integrally installing the PC column -PC beam member,

The use of concrete in the high-rise structure is limited due to the possibility of structural instability in the column-beam connection during the air delay and curing period due to concrete curing.

In order to solve the drawbacks of the conventional PC method,

Recently, researchers of the PC method of the moment joint method have been actively carried out, but it is difficult to use it widely, especially in high-rise structures due to various disadvantages such as complicated construction details, low economic efficiency and poor workability.

Therefore, the present inventor proposed a moment-resisting framework capable of eliminating the installation of the lateral shear reinforcement means such as an additional shear wall (formwork and wet construction method) or a brace while being dry type, and after the column- The frame construction of the precast framing can be carried out without piling, so that similar air and workability of the steel frame construction can be realized. Especially, unskilled workers have come to propose a PC construction method that can be done safely and quickly when only the manual is known.
