Description

[0001] The present invention relates to a rigid connection structure between upper and lower PC columns having a plate, and a rigid connection structure between the PC and the PC using the same, and more particularly to a rigid connection structure between the upper precast concrete column and a lower rigid connection structure, the same}

The present invention improves the joining of column and beam to realize a moment bonding method, that is, a strong joining by a dry method. However, the present invention improves the workability and provides a strong joining bond between upper and lower PC columns Structure and a rigid joint structure of a PC beam 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 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 proposes a moment-resisting framework capable of eliminating the installation of the lateral shear reinforcement means such as the additional shear wall (formwork and wet construction method) and the brace while being a dry type construction method.

Since the frame construction of the precast frame can be progressed, it is possible to realize similar air and workability of the steel frame construction. Especially, even if the lessee is familiar with the manual, the upper and lower PC columns having the plate And a rigid joint structure of PC beams using the same.
