A column plate (120) is attached to an external surface of the PC column (100), wherein the column plate (120) has a beam plate-connecting hole (124) and a beam upper end steel reinforcement-connecting hole (122), which are respectively formed at both ends and at an upper end. A beam plate (220) is installed at both ends of beam concrete (250) of the PC beam (200), wherein stirrups (SR) are exposed from the top of the beam concrete (250), and the beam plate (220) has a height equal to that of the beam concrete (250) and a width greater than that of the beam concrete (250) to expose a column plate connecting hole (224).

Description

Plate-based PC column-PC beam splice structure, PC girder-PC beam beam splice structure, and modular system using the same. {The rigid connection structure between the precast concrete column and the precast concrete column girder and the rigid connection structure between the precast concrete girder and a precast concrete beam using the plate, the modular system using the same}

The present invention relates to a PC column-to-PC beam splicing structure and a PC girder-PC beam splice splicing structure that utilize a plate having improved masonry joining method by improving the joining portion between column and beam, Modular system.

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 thus 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.

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. Therefore, the use of high - rise structures is limited due to the possibility of structural instability in column - beam connections.

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

Recently, the researcher of the "PC method of moment joint method" has actively carried out, but it is not widely used especially in the high-rise structure due to various disadvantages such as complicated construction details, low economic efficiency and poor workability.

Therefore, the present inventor proposed a moment-resisting frame which can eliminate the installation of lateral reinforcement means such as an additional shear wall (formwork and wet method) or a brace while being dry type. Especially, I have come to propose a PC construction method that can be constructed.
