Description

TECHNICAL FIELD [0001] The present invention relates to a reinforced concrete member reinforcing method using a multi-purpose coupler of a reinforced concrete member. [0002]

The present invention relates to a reinforcement method for a reinforced concrete member using a multi-purpose coupler of a reinforced concrete member. More specifically, the present invention relates to a multi-purpose coupler that is easily installed at both ends of a main beam installed at the periphery of a reinforced concrete column, And reinforcing concrete columns or beams or foundations.

Generally, in the vertical expansion and seismic reinforcement works for building structures, it is necessary to intensively reinforce the columns and foundation members in accordance with the increase in the load of the structure.

FIG. 1 shows a reinforced concrete column reinforced by a conventional reinforced concrete column reinforcing method.

1, the main bars (r 1) as part of the cross section expansion method on a pole 10 and the base member before the reinforcement provided so as to penetrate the upper and lower layers of the structure, and, on the other band in the same main bars (r 1) reinforced Or the reinforced concrete column 1 having been reinforced by the process of pouring the concrete 20 after the reinforced concrete column 1 is subjected to the transverse reinforcement with the transverse reinforcement r 2 such as the wire rope.

However, in such a conventional column reinforcing method, it is difficult to carry out a transverse strength to the main r 1 passing through the upper and lower layers because of the use of a band reinforcing bar or a wire rope. Particularly, it is difficult to carry out the transverse direction at a position close to the slab because the workability is high and the reinforcement can not be performed properly.

2 is a perspective view showing a head reinforcing bar 50 used in another conventional reinforced concrete column reinforcing method.

The head reinforcing bar 50 includes a reinforcing bar 52 and a head portion 54 provided at both ends of the reinforcing bar 52. A plurality of head reinforcing bars (50) are arranged between the main bars when the columns are transversely stacked. Then, when the concrete is laid, the restraining force of the concrete is increased and the strength of the column is increased.

However, since the head reinforcing bar 50 is easy to install, it is difficult to transmit tensile force to the main body because it is simply buried between concrete, and thus there is a problem that the degree of improvement of the strength of the column is greatly lowered compared to the installed amount.

Also, since the cost of the head reinforcing bar 50 is high, there is a problem in that the cost of reinforcing construction is increased.

Therefore, a method for solving such problems is required.

12 to 14, after the member r 2 is inserted into the first rotation part 150 and the second rotation part 170, the first rotation part 150 is inserted into the hinge of the connection part 140, A desired connecting angle of the member r 2 inserted into the first rotating part 150 and the second rotating part 170 can be formed by rotating the first rotating part 150 toward the second rotating part 170.

Alternatively, the first rotation part 150 and the second rotation part 170 may be directly connected to each other by a hinge 130 without a separate connection part.

In the case of such a two-stage hinge, the member r 2 and the member r 2 are connected on the same plane via the coupler 100.

The cap 400 described with reference to FIG. 11 can be used in the grip portion 300 of the coupler 100 of FIGS. 12 to 14 as well.

15 to 18 show a reinforced concrete column reinforcing method for reinforcing the multi-use transverse torsional steel (r 2 ) of the reinforced concrete column to the main shaft by using the couplers 100 and 1000 of the present invention.

First, FIG. 15 shows a view of a conventional reinforced concrete column 10 installed on a building. As shown in FIG. 15, the existing reinforced concrete column 10 is positioned between the slabs 30 of each layer to provide a supporting force.

In this state, a plurality of main rods r 1 are installed around the reinforced concrete column 10 as shown in Fig. In this step, the main rudder r 1 is arranged in a shape corresponding to the periphery of the reinforced concrete column 10.

Next, Fig plurality of main bars, such as 17 (r 1) is done by a step of installing the transverse anterior (r 2) around the use of this transverse anterior (r 2), the coupler (100, 1000) of the invention both ends of the .

In this step, both ends of the transverse torsion bar r 2 can be connected by using the couplers 1000 and 100 of FIGS. 3 to 10 or 12 to 14.

Next, as shown in FIG. 18, a step of placing the reinforcing member 20 around the reinforced concrete column is performed. As the reinforcing material 20, various materials may be used. In this embodiment, concrete, which is the same material as the conventional column, is used as the reinforcing material 20.

The reinforcement of the reinforced concrete column is performed through the above process.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
