Steel - Concrete Hybrid Using Upper Column Plate and Lower Column Plate Steel - Concrete Hybrid PC Column and PC Beam Steel Joint Connection Structure Using Upper and Lower PC Columns with Concrete Beam - to - a rigid connection structure between the upper precast concrete column and the lower precast concrete column and a rigid connection structure between the precast concrete column and the precast concrete beam,

The present invention improves the joining between the upper and lower columns and the column and the beam to improve the workability by implementing the moment bonding method, that is, the strong joining by the dry method, so that the upper column plate and the lower This paper describes a steel jointed joint structure of steel - concrete hybrid PC columns and PC beams using column - to - column joints of steel - concrete hybrid upper and lower PC columns.

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 simple method of mounting the PC beam on the PC column is one of the methods that are widely used at present, but the air is somewhat reduced, but when the lateral force such as an earthquake acts, the column-to- . 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.

(2) The method of integrally installing the PC column-PC beam member causes the concrete to be laid on the joint, which may cause structural instability in the column-beam joint during the air delay and curing period due to concrete curing The use of high-rise structures is limited.

In order to solve the drawbacks of the conventional PC method, researchers of the PC method of the moment bonding method have been actively carried out, but it is difficult to use it widely in the high-rise structure in particular 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. Steel-concrete hybrid, which can be constructed safely and quickly when only the less experienced users are familiar with the manual. Steel-Concrete Hybrid PC Columns and PC Beam Steel Joints by Using Concrete Beam-to- Joint coupling structure.
