Description

The rigid connection structure between PC columns and PC beams using temporary brackets installed on the PC columns, and the modular system using the rigid connection structures between the precast concrete columns and the precast concrete columns using the modular system using the same}
The present invention relates to a steel joint joining structure of a PC column and a PC beam using a temporary bracket installed on a PC column that improves the jointability by improving the joining portion between the column and the beam and realizing a moment joining method using a semi-dry method, And a modular system 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 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 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 proposes a moment-resisting frame that 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 temporary bracket, We have come up with a PC construction method that can be applied quickly.
