Description

The rigid connection structure between the PC column and the PC beam using the permanent bracket installed on the PC column is a precast concrete column using a precast concrete column and a precast concrete beam using the permanent bracket,

The present invention relates to a method for improving the strength of a PC column and a PC beam using a permanent bracket installed on a PC column using a permanent bracket with increased workability installed on a PC column, Coupling structure.

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, the collision with the crane caused by the collision of the PC with the PC mounted on the PC column may lead to the collapse of the column - beam connection due to the collapse of many PC members. 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 large-scale logistics structures is limited due to the possibility of structural instability during the air delay and curing period due to concrete curing.

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

Recently, the researchers of the "PC method of 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 proposes a moment-resisting frame which can eliminate the installation of a lateral shear reinforcement such as an additional shear wall (formwork and wet construction method) or a brace while being dry type. Especially, if an inexperienced person learns a manual only by using a permanent bracket, We have come up with a PC construction method that can be applied quickly.
