Description

Connect Rebar Coupler {Coupler For Rebar Connect}

[001] The present invention is intended to connect the bars with each other. Rebar with strong force

      It is about the connection rebar coupler that can be connected and fixed.

[002] Connecting reinforcing bars for use in concrete structures at construction sites

      In order to double the reinforcing bars,

      Fixed, but the work is cumbersome and the rebar center is not vertical

      Not only can it be penetrated, but because the strength of the wire is weak,

      There was a problem that the connection state is released.

 Most of the conventionally developed rebar couplers are structurally produced

       It is complicated and difficult to connect the reinforcing bar.

       There is a cost problem.

 In order to solve this problem, by placing the reinforcing bar in the same line

       Rebar couplers that can be easily connected are emerging.

         The present invention is connected to the reinforcing bar and the reinforcing bar and the binding force between the rebar and the coupler

               Reinforcement to prevent the rebar from separating from the coupler.

               In addition, the rebar is connected to the coupler by a simple rebar fitting method.

               Greatly improve work efficiency and improve working time

               Can be shortened and can be supported by poured concrete

               The purpose is to provide an improved rebar coupler.

Connected rebar according to the present invention for achieving the above object

      The coupler has an inlet through which rebars are inserted at each of the upper and lower ends thereof.

      The inner diameter gradually increases from the entrance to the other side.

      The tapered part is formed and supported by the bar of bar

      As the plurality of pieces are retracted, the locking protrusions of the pieces are placed on the outer surface of the rebar.

      It is characterized in that the compression.

 According to the present invention, before the reinforcing bar is inserted into the coupler body

       The knits stay open when they are joined to the ribs,

       When inserted, the knitting body is moved and contracted by the elastic force of the spring

       Strongly compresses the outer surface of the rebar, so that it can be firmly fixed

       do. Therefore, the configuration and operation is simpler than before, and the assembly is easy.

       It works.

 In addition, the receiving groove is formed at the end of each piece by the spring

       Fixed to prevent derailment and maintain multiple gaps

       Therefore, when the reinforcement is inserted afterwards,

       The knits will be able to fix the bars with uniform force at about the same time.

 In addition, the inner surface of the outer cover ribs protruding at the entrance adjacent to each other

       Including but not limited to adjacent gaps between ribs

       And the knitting pieces which are inserted into the outer cover and combined by shape fitting

       It is desirable to prevent derailment.

 The present invention is a structural production is different from the conventional developed coupler

        According to the easy coupling method, the user can use as a coupler

        Time consuming, of course, has the effect of bringing economic advantages.

 Connect rebar coupler according to the present invention with reference to the accompanying drawings

        (Hereinafter, simply referred to as 'coupler') will be described in detail.

 First, the coupler according to the present invention shown in Figure 1 and the outer cover 10 and

        Inner configuration 20, the elastic body 30, the connector 40,

        Is done.

 Connector 40, as shown in Figure 2, the outer cover 10 and each other

        Body and configuration to ensure a tight connection

        It consists of a configuration including a receiving groove (41,).

 Connector 40 is the outer surface of the screw thread for coupling with the outer cover (10)

        It is formed on the outer surface, the connector receiving groove 41 and the outer diameter of the elastic body 30

        Formed to have the same diameter, the coupling coupling groove 21 and the connector

        Stable support within the receiving groove 41 and elasticity of the inner cover 20

        Is to be able to restore.

 Elastic body 30 is as shown in Figure 1, the reinforcement into the outer cover 10

        The outer cover 10 through the elastic force after being drawn or drawn in

        The inner piece 20 provided therein to move stably,

        It is a configuration to be able to be placed in place.

 The elastic body 30 is to be restored elastically in the connector receiving groove 41

        When the rebar is drawn in, the rebar is in the outer cover (10)

        After the elastic body can contract maximum in the advancing direction,

        The inner piece 20 is pushed out by moving the inner piece 20 moved by the elastic force.

        It is a configuration to be able to be placed in its position.

 The outer diameter of the elastic body 30 has the same diameter as the receiving groove 41 in the connector

        Formed and provided to have no flow in the connector receiving groove (41)

        The inner piece coupling groove 21 can be supported by the elastic force,

        The coil spring is used for the elastic body 30 in the design.

 The outer body 10 is inserted through the reinforcing bars are the reinforcing bars are connectors

        A cylinder with both sides open to be introduced into the partition groove 42

        It consists of a shape, the inside of the tube shape with a hollow portion

        It is formed to have.

 Rib 11 has an inverted triangular prism shape to the outer surface of the inlet (10)

        Protruding radially adjacent to each other.

 Neighboring spacing of the ribs 11 may be inserted into the inner piece 20 fixed

        It should be spaced apart, but its length (10mm) is easy to rebar

        At the same time it can be combined with the inner body 20 to be fitted

        Make sure

 And, the inner piece 20 is combined to fit the inside of the outer body (10)

        To prevent the inner piece 20 drawn into the interior from being separated

        In addition, the locking projection 22 formed on the inner surface of the inner piece 20 is

        Reinforcing bars introduced into the outer body 10 do not interfere but

        The rebar is formed to have a shape that cannot be retracted back

        To increase the fixing force between the rebar and the inner piece 20.
