BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

As shown in Figs. 1 to 3, the index plate connecting structure of the present invention is used to continuously connect the index plate 1 embedded in concrete.

In this case, the index plate 1 is briefly examined, and the extension ends 3 are formed at both sides of the core 2 having a cylindrical shape in the center thereof.

In addition, a plurality of engaging projections 4 are formed in a single shape on both sides of the extension end 3 along the longitudinal direction at equal intervals.

Such, the core member portion 43 is formed to be raised in the center of the hollow body 42 so that the core member 2 formed in the center of the index plate 1 is inserted.

At this time, the body 42 is a rectangular band shape when projecting the cross-section, the core member 43 is formed to protrude outward from the center portion.

In addition, a plurality of ribs 41 are formed on the outer circumferential surface of the body 42 along its length.

Referring to the manufacturing method, operation, and effects of the present invention configured as described above are as follows.

As shown in Figure 4 to 6, the manufacturing method of the connecting structure 50 for inserting and connecting the opposite ends of the continuous index plate (1) is a polyvinyl chloride powder (10) Prepare.

Thus, the prepared polyvinyl chloride powder 10 is added to the melting tank 20 to melt in the range of 150 ~ 200 ℃.

Thereafter, the molten polyvinyl chloride powder 10 is passed through the extrusion mold 40 while flowing by the flow means 30 to be extruded into a hollow rectangular cylindrical shape in which a plurality of ribs 41 are formed on the outer circumferential surface thereof. .

Here, the flow means 30 may be manufactured in the form of a transfer screw.

Thus, the extrusion is molded at the same time using the cutting knife (5) to the length to be used after room temperature cooling to complete the connection structure (50).

In this case, in order to use the connector structure 50, the manufacturing is completed, first, it is used in the process of pouring concrete when building the outer wall made of reinforcement and concrete at the construction site.
