Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hybrid RCB connection structure and a construction method thereof,

The present invention relates to a method of constructing a structure for connecting a wall and a slab of a building to a conventional structure by connecting a conventional wall and a slab to the existing structure using a hybrid rail PC beam, And the other end is connected to a hybrid raman PC beam connection structure for horizontal expansion connected by moment joints and a construction method thereof.

Another aspect of the present invention is to improve the joint between the PC column and the PC beam to realize the moment bonding method by the dry method. In particular, the upper and lower wall type PC column interconnection structure utilizing the mounting bracket mounted on the PC column of the wall type, And a RC or SRC coupling structure of the PC type PC board and the PC board using the same.

In the remodeling process of the building, horizontal expansion is frequent in addition to vertical expansion.

In the case of the conventional horizontal enlargement, most of the existing wall and slab are formed by a wet method by partially or completely removing the enlarged surface or extending the existing wall and slab.

In this case, it is pointed out that the construction period and the construction cost increase as well as the excessive waste material occurrence, and the predetermined construction quality can not be maintained in the case of non-skilled workers.

In addition, the floor height of the conventional wall-mounted apartment is small, so that it is not possible to cope with the existing slab dancing when the horizontal extension is performed with the ramenton. However, since the hybrid self-positioning connection structure of columns and beams for horizontal expansion is composed of a hybrid member of steel and PC concrete, the floor height can be reduced, and horizontal enlargement can be made so that the slab of the existing building can correspond to the floor. In addition, we propose a dry method to overcome the problems of existing wet method.

Accordingly, the present inventors have found that, in the process of building expansion or remodeling, a frame of a part to be horizontally expanded without changing the existing wall and slab is connected to an existing structure by using a hybrid rail PC beam, Has developed a hybrid RC frame connection structure and its construction method for horizontal expansion connected by moment joints.

In recent years, the use of PC (precast concrete) method has been increasing to secure the 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.

Also, it is true that the architectural planning using the existing rectangular frame of the square shape makes it difficult to construct the flat structure which is one of the advantages of the flat type wall house. Recently, it is widely known that some construction companies are making efforts to reshape the existing flat type apartment house despite the disadvantages of the use of form and frequent reconstruction. In order to meet the needs of this market, the synthetic ramen apartment developed through this patent was developed as a ramen precast frame which enables the structural planning to avoid the shape of the wall - like structure. Therefore, it is expected that it will be possible to supply eco - friendly, long - life precast rayman apartment houses with resource saving, sustainable, and economic efficiency while maintaining the advantages of the existing in - situ walled apartment complexes. In this study, we developed an inelastic and nonlinear finite element modeling technique for efficient structural design of composite PC structure system, and developed an animation technique to grasp structure history of structural frame at a glance. This method is expected to be applied not only to apartment houses but also to active applications such as domestic general construction, overseas construction, plant construction, and new expansion.

Therefore, the present inventor proposes a moment-resistant framework capable of eliminating the installation of a lateral shear reinforcement means such as an additional shear wall (formwork and wet construction method) or a brace in addition to a dry construction method. Particularly, , We have proposed RC / SRC coupling structure of wall PC column and PC beam by using the coupling structure of upper and lower wall PC columns.
