Description

The rigid connection structure between precast concrete column and precast concrete beam of steel plate -

The present invention relates to a steel-concrete hybrid PC column and a steel-concrete hybrid PC column using a movable plate for realizing a steel-jointed connection only by joining a steel material before a joining portion by implementing a moment joining method, that is, a steel joining by improving a joining portion between a column and a beam, The present invention relates to a rigid joint structure of a PC beam.

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 proposed a moment-resisting framework capable of eliminating the installation of the lateral shear reinforcement means such as an additional shear wall (formwork and wet construction method) or a brace while being dry type, and after the column- The frame construction of the precast frame can be carried out without the pouring and the like, so that the similar air and the constructability of the steel frame construction can be realized. Especially, the unskilled workers have come to the proposal of the PC construction method of the rigid joint structure of the steel - concrete hybrid PC column and the PC beam using the movable plate which can be constructed safely and quickly when only the manual is known.
