Description

The hybrid structure of column and beam, the hybrid structure of girder and beam,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hybrid bonding structure of a column and a beam and a hybrid bonding structure of a girder and a beam in a steel-reinforced hybrid PC including a pillar steel frame and a general PC not including a pillar steel frame.

For a steel-reinforced hybrid PC with a pillar steel frame and a general PC without a pillar steel frame,

When constructing the connecting portion between the column and the beam, conventionally

The following two methods are mainly used.

(1) It is a wet laying method of joining part where the general PC beam and column are installed and then the joint part is poured into concrete. This requires a lot of preparatory processes for casting the concrete such as formwork in the joint, and it can cause serious safety problems by exposing the reinforced concrete until the concrete is cured. In fact, there have been instances where the collapse of a joint has led to a loss of life.

(2) Simply place the PC beam member on a pedestal such as a cobell placed on a column. In this method, it is possible to reduce the construction period to some extent. However, since a separate lateral load resistance system must be provided to support the lateral load such as an earthquake, additional processing is required and the construction cost and construction period are increased again. In addition, since the both ends of the frame are simply joined, a large amount of structural reinforcement is required in the center of the beam where the moment is applied to support the vertical load.

However, the present invention can provide the following advantages by providing a structure detailing a column and a beam plate and connecting them with a bolt.

(1) In the present invention, a plate joint joined with a bolt to a column and a beam is configured to effectively support tension and compression forces due to moments. Therefore, it is possible to convert the conventional simple joint into moment joint, and it is not necessary to reinforce the structure required in the center of the beam where the additional transverse resistance system or the longitudinal moment, which is required in the conventional PC joint, is required. In the present invention, since the beam ends are rigidly connected, the load can be supported even at the beam ends, and thus the structure reinforcement at the center of the beam where the longitudinal vibration acts can be drastically reduced.

(2) In addition, this joint is dry connection using mechanical connection method, and it is possible to improve not only the air saving but also the safety at the construction site since the water such as water is not used at the time of joining part construction . Especially, it is possible to realize the simplification and standardization of the process as well as the reduction of the construction cost by making the form and the wet concrete unnecessary which are essential elements of the concrete pouring. Design standardization will organically link the entire design process and the construction process, enabling a systematic construction plan, which will contribute significantly to air reduction and cost reduction.

(3) The joining part of the present invention is a dry joining method composed of a plate and a bolt, so that not only the structure but also the disassembly can be easily performed, and the concept of DFD (Design For Dismantle) can be realized. It is not a dismantling of lifesaving structures by explosives, but it provides a breakthrough technology that can be easily disassembled and reassembled in other areas as needed. This makes it possible to realize an economical, sustainable construction method that is easy to construct and dismantle. It is a breakthrough method that can meet the global environmental conservation policy.
