2A is a perspective view of a fabrication sequence of a high-strength continuous support-type double plate in which steel and concrete are synthesized according to an embodiment of the present invention, and FIG. 2B shows a side view of the double plate shown in FIG. 2A.

Referring to Figures 2a to 2b, a high-strength continuous support type reinforcing plate that synthesizes steel and concrete according to an embodiment of the present invention is located on one side of the uneven plate-shaped steel plate 100 and the steel plate 100 And it is formed to fill the recess 110 on one side of the steel plate 100 and has a specific thickness from the surface of the iron portion 120 on one side of the steel plate, it can be confirmed that the one side surface includes a flat concrete plate 200.

By varying the spacing and depth of the concave portion 110 and the convex portion 120 of the steel plate 100, it is possible to diversify the self-weight and maximum allowable load of the perforated plate 10 itself.

The concrete plate 200 is formed to fill all the concave portions 110 on one side of the steel plate 100 and at the same time to have a height h from the surface of the iron portion 120, and by varying the height h, the weight of the perforated plate 10 itself And the maximum allowable load can be diversified.

In addition, in the state where the concrete plate 200 is not formed, it is disposed on the surface of one side of the steel plate 100, and may further include a reinforcing steel plate 300 that couples a plurality of side portions to each other.

The concavo-convex steel plate 100 is a structure that can prevent the bending or sagging in the longitudinal direction of the concavo-convex shape or improve its performance, and the reinforcing steel plate 300 exhibits the bending or sagging phenomenon in the longitudinal direction of the reinforcing steel plate 300. It is a structure that can prevent or improve its performance.

Also, referring to FIGS. 2A to 2B, steel plate-bolt holes 111 and 121 are formed in the steel plate 100 and the concave portion, and the reinforcement plate 300 has one side convex portion 120 of the steel plate 100. Reinforcing steel plate-bolt hole 310 is formed coaxially with the steel plate-bolt hole 121 formed in), and the concrete plate 200 has a larger diameter than the reinforcing steel plate-bolt hole 310. 210 is formed coaxially with the reinforced steel plate-bolt hole 310 and the steel plate-bolt hole 121.

The steel plate 100 is formed coaxially with the steel plate-bolt 111 formed on one side of the concave portion 110, and is recessed in the direction of one side from the other side of the steel plate 100 to be embedded in the nut 221. A bolt coupling groove 220 including a may be further provided.

Figure 3 shows a side view according to the assembly order of the upper and lower reinforcing plate using a high-strength continuous support-type reinforcing plate composited with steel and concrete according to an embodiment of the present invention.

Referring to FIG. 3, by superimposing and assembling a high-strength continuous support type double plate composited with steel and concrete according to an embodiment of the present invention shown in FIGS. 2A to 2B, it can be constructed in a temporary passage of a vehicle.

As shown in Figure 3a to Figure 3 (b), it is arranged to overlap the perforated plate 10 shown in Figures 2a to 2b, the steel plate 100 of each of the perforated plate is arranged to face each other, each unevenness It is fastened so that the shape is engaged. At this time, by bolting the bolt 222 and the buried nut 221 to each other, the upper perforated plate 10-2 disposed on the upper side and the lower perforated plate 10-1 disposed on the lower side can be structurally combined.

In addition, after the bolt 222 is fastened, a foreign material or the like is inserted into the concrete-bolt hole 210 or the head of the bolt 222 is prevented from wearing, and a safety cap 223 may be further provided to prevent noise when driving the vehicle. .

As can be seen in Figures 3a to 3b, when overlapping and assembling a high strength continuous support type double-sided composite plate of steel and concrete according to an embodiment of the present invention, one side and the other side is exposed to the concrete plate 200, after construction The road surface will form a concrete road surface.

Therefore, when it rains or snows, the sliding phenomenon may be reduced compared to the steel surface of a conventional perforated plate.

In addition, since a plurality of points are fastened to each other between the upper reinforcing plate 10-2 and the lower reinforcing plate 10-1, and the concrete plate 200 of the lower reinforcing plate 10-1 is assembled in contact with the support beam, The noise due to collision and friction of the upper reinforcing plate 10-2, the lower reinforcing plate 10-1, and the support beam may be reduced.

Figure 4a is a side view assembly assembly of the upper reinforcing plate and the lower reinforcing plate using a high-strength continuous support type reinforcing plate composited with steel and concrete according to an embodiment of the present invention, Figure 4b is a steel and concrete according to an embodiment of the present invention It is a plan view of the staggered construction of the upper and lower peritoneal plates using the composite high strength continuous support type peritoneal plate.

Referring to FIG. 4A, one lower perforated plate 10-1 and one upper perforated plate 10-2 may be arranged such that some areas overlap each other.

That is, as can be seen in Figure 4a, one upper perforated plate (10-2) is superimposed on the two lower perforated plates (10-1), at this time using the same size of the perforated plate (10) upper perforated plate (10-2) When constructing the upper and lower perforated plates 10-1, one upper perforated plate 10-2 or lower perforated plate 10-1, as shown in FIG. 4B, has four lower perforated plates 10-1 or upper perforated plates, respectively. (10-2).

As described above, in the conventional perforated plate, since the flat rectangular parallelepiped-shaped perforated plates are arranged horizontally, even if they are combined, they cannot be combined so that there is no gap between the opposite end faces of each of the perforated plates. Therefore, there is no choice but to be in contact with friction between the two perforated plates, and the resulting noise, as well as wear and tear, are inevitable.

3A to 3C and FIGS. 4A to 4B, a high strength continuous support type perforated plate obtained by synthesizing steel and concrete according to an embodiment of the present invention includes an upper perforated plate 10-2 and a lower perforated plate 10 during construction. It is separated by -1) and is combined with a plurality of other perforated plates 10 where one perforated plate 10 overlaps, and is fastened in a plurality of bolt holes 111, 121, 210, 310, so that continuous support is possible. , Has the advantage of minimizing noise and friction.

That is, since the upper and lower reinforcing plates 10-2 and 10-1, the concave-convex shape is zigzag-fitted and fastened with a plurality of bolts 222, the upper reinforcing plate 10-2 and the lower reinforcing plate 10-1 ) Up and down and lateral collision or friction can be significantly reduced.

In addition, if the position of the lateral end face of the perforated plate 10 is adjusted, at the time of construction, the upper perforated plate 10-2 and another upper perforated plate 10-2 adjacent to the side and the lower perforated plate 10-1 Another lower perforated plate 10-1 adjacent to the side may be spaced apart from each other, and since the spaced state can be easily maintained, there is no collision or friction, and thus noise and vibration can be minimized.

In particular, the lifting phenomenon of the perforated plate shown in FIG. 1 may be improved.

The accident due to the lifting phenomenon of the peritoneal plate shown in FIG. 1 is a phenomenon that may occur in a state in which the individual peritoneal plates separated from each other are transversely arranged. This may be caused by poor or lateral pressure acting on the perforated plate when the vehicle is suddenly stopped.

That is, as described above, in the conventional perforated plate and its construction method, since a plurality of perforated plates are horizontally assembled and disposed on the support beam, local buckling occurs in a specific single perforated plate, or each other on a path through which lateral pressure is transmitted. When a step is formed between adjacent perforated plates, there is a possibility that a lifting or bending phenomenon of the perforated plate as shown in FIG. 1 occurs.

However, as can be seen in Figure 4, in the staggered construction method of the upper and lower reinforcing plates using a high-strength continuous support type reinforcing plate in which steel and concrete are synthesized according to an embodiment of the present invention, the vertical direction and the transverse direction generated from the passing vehicle The upper reinforcing plate 10-2 to which a load is applied is not directly fastened to another adjacent upper reinforcing plate 10-2, but is indirectly coupled through the lower reinforcing plate 10-1.

At the same time, a plurality of coupling parts, that is, a combination of a plurality of bolts 222 and a buried nut 2210 and an uneven shape of the steel plate 100, the upper reinforcing plate 10-2 and the lower reinforcing plate 10-1. All of these overlapping faces are joined up and down.

Particularly, as shown in FIG. 4B, the perforated plate according to an embodiment of the present invention includes one upper perforated plate 10-2 or one lower perforated plate 10-1, or a plurality of lower perforated plates 10-1, or It will be combined with a plurality of upper perforated plates (10-2).

Accordingly, the vertical and transverse loads applied to the specific upper reinforcing plate 10-2 are all adjacent lower reinforcing plates 10-1 and another adjacent upper reinforcing plate 10-1 coupled to the lower reinforcing plate 10-1. By dispersing in -2), it not only provides the function of a continuous support type perforated plate, but also distributes the load applied from a traffic vehicle evenly among a number of adjacent perforated plates, thereby minimizing the fatigue accumulation of individual perforated plates and withstanding the same load. There is an advantage that can be applied to a more lightweight double plate.

In addition, in manufacturing a single perforated plate 10, unlike a conventional double plate, by excluding the welding process, the production and economic efficiency can be improved, and the uneven shape of the steel plate 100 and the material or thickness of the concrete plate are varied. By forming, there is an advantage that can produce a double plate (10) with a variety of deflection bending load and self-weight.
