Description

One-Touch Type Steel Reinforcement Coupler for Concrete Construction}

The present invention relates to a one-touch rebar coupler for interconnecting the reinforcing steel used in the reinforced concrete structure, more specifically, it can accommodate the deformed steel in both sides to connect the two to four deformed reinforcing bar connecting ends in the longitudinal direction. The present invention relates to a one-touch rebar coupler that can improve the construction and reduce the production cost according to the product production by improving the structure and fastening force of the rebar connection device in which the connection of the deformed steel is carried out quickly and easily on the work site. .

In general, concrete is a composite composition in which cement, sand, gravel, water, etc. are mixed at a suitable ratio, and the compressive strength is relatively high, but the tensile strength is very low compared to the compressive strength, and has a property of easily cracking. In order to increase the tensile strength of the concrete, it is installed by binding the reinforcing bars in the formwork where concrete is poured, and then placing concrete to reinforce the strength of the concrete.

This conventional reinforced concrete structure is excellent in compression and tensile strength, and can be used to construct various types of structures, as well as its physical properties are widely used in various construction and civil works.

Rebars used in reinforced concrete are circular rebars and deformed rebars. Circular reinforcement means that there are no nodes on the surface of reinforcing bars. There is). Deformed rebars have greater adhesion to concrete than circular rebars, and when cracks occur in concrete, the width of cracks decreases. Therefore, deformed rebars are generally used for main reinforcing bars.

There are two types of reinforcing bars: SBC and SBD. The length of the rebar is 3.5 ~ 10.0m unless ordered separately, and 6-12m when ordered. Circular reinforcement means that there are no nodes on the surface of the reinforcing bar, and the deformed reinforcing bars have nodes and ribs, ribs formed in the axial direction and nodes formed in the circumferential direction. Deformed steel reinforcement has greater adhesion with concrete than circular reinforcement, and the crack width decreases when the concrete is cracked.

In general, cast rebars are used instead of circular rebars. Deformed steel bars represent the diameter and cross-sectional area of the nominal diameter and nominal cross-section. The nominal diameter is called the nominal cross-sectional area, assuming that the weight per unit length is a circular rebar, such as a deformed reinforcing bar, and this diameter is calculated from the nominal diameter and the nominal diameter. The elastic modulus of the reinforcing bar is 2.4 million kg / cm 2 and the linear expansion coefficient is about 1 × 10 −5 / ° C., which is almost the same as that of concrete.

In order to install the formwork in which concrete is cast in the prior art, the reinforcement work is arranged to arrange the deformed reinforcing bars in a predetermined form. As the deformed reinforcing bars are generally manufactured in a standardized length, the work of interconnecting the deformed reinforcing bars of the predetermined length during the reinforcing work is performed. Necessary, such a conventional method of connecting the reinforcing bar has been proposed, such as lap joint method, welding joint method, screw joint method, connecting device joint method.

The lap joint method is a method of winding wires at the ends of overlapping rebars, which has the advantage that the reinforcement work is relatively easy. Due to its weakness, safety problems have been pointed out.

On the other hand, the welding joint method is a method of welding the ends of the deformed rebars to each other, the strength of the connection portion is good, there is no problem, but the work is very cumbersome and takes a lot of time, the construction is delayed. Screw joint method is a method for connecting the interconnection by processing the screw on the connecting end of the deformed reinforcing bar requires a facility for processing the connecting end, there is a problem that the construction is impossible in a narrow space.

In addition, the connecting device joint method is a method of connecting both ends of the deformed reinforcing bars using the connecting device, the prior art has a problem that the deformed steel is shaken inside the connecting device to reduce the tensile strength of the reinforced concrete There was a large number of parts constituting the connection device and the structure is complicated, the cost was high according to the production of the product, there was a problem that the work is time-consuming, delaying the construction as well as raising labor costs.

The present invention has been made to solve the above problems, it is possible to quickly and simply perform the connection of the reinforcing bars without binding or bending the wires of the reinforcing bar, it is possible to reduce labor costs by the reliability and high construction of the strength of the connection portion In addition, it is possible to shorten the air and finally provide a one-touch rebar coupler of the straight, elbow, tee or cross type that can reduce the construction cost.

The coupler body has a conical columnar shape, and the coupler body has a reinforcement hole in which a deformed steel is inserted in the center, and a coupler lock is inserted in the longitudinal direction from the circumference and the lock insertion opening is equal to the number of the coupler locks. A spring has a first insertion hole into which one end of the spring is inserted, and the lock insertion opening is formed in the lock insertion opening in which the coupler lock is placed in the longitudinal direction and slides, and the coupler lock is formed by cutting a rectangular parallelepiped diagonally. The inclination angle cut by is equal to the inclination angle of the conical column of the coupler body, and the coupler lock is inclined in one direction so that it can be easily inserted when the node of the deformed rebar is inserted in the longitudinal direction and can be caught when it is removed, and the spring The spring is inserted into the second insertion hole is formed, the coupler housing is A plug body and the coupler lock are separated into a mail housing and a female housing inserted therein, and the mail housing and the female housing are inserted into a socket type and are coupled, or separated into the same shape and joined together to be externally welded to each other.
