Abstract

The present invention relates to a flattened reinforcing bar joint used to connect the reinforcing bar used as a skeleton thereof when constructing concrete in construction and civil engineering.

Conventionally, rebars are connected in various ways, and the methods are listed as follows.

1. Method of reinforcing pore joint

Conventionally, the most frequently used method is easy to connect by tying up the reinforcing bars to be superimposed with overlapping iron wires, but it is still used a lot, but the drawback is that the connection part of the reinforcing bar has no tensile force at all. After the construction of concrete, typhoons, heavy rain, earthquakes, or sudden shocks cannot absorb the shocks, which may cause fatigue to accumulate in the reinforcing bars and collapse.

2. Rebar processing connection method

It is widely used as a method of making and connecting couplings after machining both ends of connecting bars.

end. Long rebar must be transported to the processing plant. At this time, the logistics cost is high, causing huge traffic jams and causing problems in other industries.

I. It is very time-consuming and wasteful of rebars because it needs to be processed after calculating and cutting the rebar to be used based on the design drawing.

All. There are many concerns that the construction period may be delayed due to traffic accidents or traffic jams.

The present invention was devised to solve the above problems, and the gist of the present invention is a method of connecting reinforcing bars using a pair of two pieces. The knitting body has a recessed groove so that the inner surface thereof is caught by the protruding jaw of the reinforcing bar, and the outer surface is made of an inclined portion so that the body can be easily and completely connected to the body. When reinforcing bars, assemble the fabric to face the rebar, leaving only one protruding jaw at the end of the reinforcing bar, and then screw it tightly to the inner slope of the end of the joint body. Since the inclination angle of the outer inclined portion and the inner end portion of the inner end portion of the body is the same as the wedge role is formed as a strong reinforcing bar connection. After finishing the reinforcing work, the mortar is used as the mortar inlet in the seam body when the concrete is finished. The inside of the seam body is completely vacuumed and there is no fear of corrosion even if it is embedded in concrete for a long time.

Description

JOINT COUPLER FOR STEEL BAR}

The present invention relates to a reinforcing seam used when connecting the reinforcing bar used as a frame when constructing concrete in construction and civil works.

In the conventional method of connecting reinforcing bars, both ends of the reinforcing bar are processed (swelled or screwed), and then connection couplings are made of reinforcing bars. In order to process the rebar, the long rebar must be transported to the processing plant. At this time

1. Logistics costs are high.

2. Cause traffic jams.

3. You need equipment for processing.

4. Since the rebar should be cut according to the usage of the rebar, the design cost, time waste and rebar waste are generated.

5. If the processing part is damaged due to carelessness (traffic accident, etc.) during transportation, the reinforcing bar may not be connected.

6. Construction period is delayed.

As described above, many problems may occur in the related art.

The present invention was devised to solve the above problems, and the gist of the present invention is that the joint body is made of a stronger material than the reinforcing bar, and the mortar inlet is penetrated at a right angle in the center thereof (penetration). In the center of the seam body, a hole is formed in the longitudinal direction (penetration), and both ends of the seam body are formed with an inclined portion and are formed with a screw portion at the end thereof. Importantly, the connecting body is formed into a recessed groove so that the inner surface is caught in the reinforcing bar, and the outer surface of the body is formed by the inclined portion (an inclination angle is symmetrical with the inclined portion of the inner surface of the seam body), and the two pieces are one set. When connecting the reinforcing bar, assemble the fabric with the end of the reinforcing bar facing each other, and then insert the screw into the inclined part of the inner body of the joint to tighten the reinforcing bar. In the rebar connection process, the recessed groove of the inner surface of the knitting body hangs the jaw of the reinforcing bar, and the outer surface inclined portion of the knitting body slides to the inclined portion of the inner surface of the seam so that the knitting body acts as a wedge and strongly compresses the reinforcing bars and the reinforcing bars are assembled. At this time, the body is separated into two, easy to assemble and easy to act as a wedge makes a strong reinforcing bar connection.

When the concrete is finished after the rebar connection, the concrete mortar fills all the empty space inside the seam through the mortar inlet of the seam.

therefore

1. Because the inside of the joint body is completely vacuumed, there is no fear of joint oxidation (corrosion).

2. The mortar is injected into the empty space inside the joint body to make stronger reinforcing bar connection.

3. Since the inside and outside of the joint body are concrete together, it can be a complete concrete work.

As described above, the flattened reinforcing bar joint of the present invention can be easily and strongly connected to the reinforcing bar assembly, and there is no fear of corrosion even if it is embedded in concrete for a long time.

Referring to the present invention in detail based on the drawings as follows.

Mortar injection hole 1 'is drilled at right angles to the center of the joint body 1 made of a material superior to the reinforcing bar, and a hole 1 "is drilled in the longitudinal direction at the center of the joint body 1; (Penetration) and the inner body of the left and right end ends of the joint body (1) is formed with an inclined portion (2), and the joint body of the threaded portion (4 ") so that the tightening screw (4) can be screwed on the next part ( 1) is formed.

Two pieces of the knitting body 3 were formed into one set, and the outer surface of the knitting body 3 became the inclined part 3 ', and the inclination angle was made to be symmetrical with the angle of the inner inclined part 2 of the joint body 1. A recess 3 'is formed in the inner surface of the knitting body 3 so as to catch the protruding jaw 5' of the reinforcing bar 5. To connect the reinforcing bar, the knitting body 3 is placed at the end of the reinforcing bar 5. After the two are assembled facing each other (6), they are inserted into the inner inclined portion (2) of the joint body (1) and tightened with screws (4). (5 ') and the outer inclined portion (3') of the knitting body (3 ') is tightened while acting as a wedge to the inner inclined portion (2) of the seam body (1) to connect the reinforcement (5) strongly give. After the reinforcing bar is completed, the concrete mortar fills the empty space inside the seam body 1 through the mortar inlet 1 'formed in the seam body 1 during concrete work. The interior is fully vacuumed and can act as a complete reinforcing bar to prevent corrosion.

As described above, the design of the seam body (1) and the knitting body (3) is made of a material stronger than the reinforcing bar, leaving only the reinforcing bar (5 ') of the reinforcing bar (5') of the reinforcing bar (5) to connect two pieces of knitting (3) After assembling (6) to the left and then tightened the screw (4) to the internal inclined portion (2) of the joint body (1), the reinforcing bar connection is completed.

[Characteristic]

1. The hole (1 ") of the seam body (1) is an empty space that allows the rebar end to fit well.

2. The two pieces (3) of one set is easy to work with the reinforcing bar (6) and wedge role.

3. The inclination angle of the inner inclined portion 2 of the joint body 1 and the inclined angle of the outer inclined portion 3 'of the knitting body 3 are symmetrical, so that the knitting body 3 has a wedge action when the final screw 4 is tightened. Strong reinforcing bar connections are formed.

4. The mortar injection hole (1 ') formed in the joint body (1) is filled with the empty space inside the joint body (1) when the concrete mortar is filled in the interior of the joint body (1) is completely vacuum Even if it is embedded in concrete for a long time there is no risk of corrosion and serves to allow the joint body (1) and concrete to be formed integrally.

With the above effects, the concrete works of building and civil engineering are completely done, so it is a very useful design because it is possible to perform a complete reinforcing bar work that can withstand the shock and vibration from typhoon, heavy rain, earthquake, etc.
