Description

The rigid connection structure between the upper precast concrete column and the lower precast concrete column and the rigid connection structure of the precast concrete girder using the same}

The present invention is to improve the connection between the column and the beam to implement the moment bonding method, that is, the steel joint by the dry method, but to increase the workability, the steel joint coupling structure between the upper and lower PC pillars for the steel joint implementation only by the connection of the steel before the joint installation The present invention relates to a rigid joint coupling structure of a PC beam.

In recent years, the use of a precast concrete (PC) method is increasing to secure constructability and to save air.

In the conventional PC method, (1) a method of simply mounting a PC beam on a PC column, (2) a method of integrally placing a PC column-PC beam member, etc. are mainly used.

(1) The method of simply mounting the PC beam to 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-beam connection is a simple joint, and thus the moment cannot be transmitted. . Therefore, it is necessary to install additional shear wall, brace, etc. as a means of lateral reinforcement, so that the construction cost and air increase are inevitable without meeting the advantages of the PC method designed for air reduction.

In addition, the PC beam simply mounted on the PC column may be a cause of safety accident by the separation of the column-beam connection. Therefore, the use of the high-rise structure is limited because of the possibility of causing structural instability at the column-beam connection.

(2) The method of integrally placing the PC column-PC beam member is to cast the joints, because of the air delay caused by the concrete curing and structural instability at the column-beam joint during the curing period may be caused. The use of the high-rise structure is limited.

In order to solve such disadvantages of the conventional PC method, researchers of the PC method of the moment bonding method have been actively made, but it is difficult to be widely used, especially in high-rise structures, because of various disadvantages such as complicated construction details, low economical efficiency, and poor workability. .

Accordingly, the present inventor proposes a moment resisting frame which can eliminate the installation of lateral reinforcement means such as a dry construction method and an additional shear wall (die and wet method) or brace.

The present invention can implement a similar air and workability of the steel frame construction because the frame construction of the precast frame can be progressed, and especially the unskilled construction of steel joints between the upper and lower PC columns that can be safely and quickly construction only if you know the manual and It is a rigid joint coupling structure of PC beam using this.
