In addition, the road paving concrete panel 100 using the expansion pressure of the present invention, as shown in the plan view and bottom view in Fig. 3a and 3b, respectively, one side edge of the concrete body 110 is four of the four-sided concrete body 110 Two edges are adjacent to each other, and the other edge is composed of the other two edges. Therefore, through such a structure, each of the concrete pavement panels 100 for paving roads using a plurality of adjacent expansion pressures are inserted into the fixing slots 130 formed at the other two edges of the fixing member 120 protruding from the edges of the two sides. 160 can be integrally coupled through.

As described above, when the road paving concrete panels 100 using the expansion pressure of the present invention are inserted into and disposed in the fixing slot 130 of the adjacent concrete panel 100, the fixing member 120 of the adjacent concrete panel 100 is disposed. As the fixing member 120 secures a space that can be moved up and down inside the fixing slot 130, the concrete panels 100 adjacent to each other can be individually adjusted in height.

In addition, the road paving concrete panel 100 using the expansion pressure of the present invention, as shown in Figure 4, the groove 112 is formed in the center of the upper surface of the concrete body 110 to form a cross section of the concrete panel 100 It can be made of a line-shaped concrete panel 100b for bimodal tram can be reduced.

That is, the road paving concrete panel 100 using the expansion pressure of the present invention shown in FIG. 1 is a general road paving general concrete panel 100a having a flat top surface, but the structure shown in FIG. Groove 112 is formed in the center of the upper surface is a line-shaped concrete panel 100b for bimodal tram with a reduced cross section of the concrete panel 100.

Even in the structure of the track-type concrete panel 100b for bimodal tram, a concave chamfer 140 is formed on the lower surface of the concrete body 110, for example, on the lower surface of the four corners 110a, and the height adjusting means 150 is formed. It can be mounted.

Even in such a structure, the chamfer 140 may be installed at a number of places, for example, two places, four places, or six places, depending on the size, weight, and shape of the concrete body 110.
