1 is a view for explaining the configuration of the device according to the invention on the top plate of the piers
2 is an enlarged view of another embodiment of the main part of FIG.
3 is an enlarged view illustrating main parts of FIG. 1;
4 and 5 are diagrams for explaining the operation of the present invention.

1 is a view for explaining the present invention.

As shown in the figure, a concave groove is dug in the end of the upper plate 1 installed on the pier 2, and a plate 3 made of iron plate is integrally installed therein, and a link piece 10 is provided on the upper plate between the two piers. do. The upper plate 1 is a concrete structure in which the reinforcing bar is reinforced, and the plate 3 is integrally formed with the upper plate 1.

A lower plate 11 is installed at the lower end of the link piece, and the pin 12 is coupled to the link piece 10, but a pressing plate 13 is further installed above the installation position of the pin 12, and the pressing plate 13 is different. It is fixed by the fixing piece 17 to the plate 3 of the upper plate 1

The end of the link piece 10 is provided so that the lower plate 11 is accommodated in the stepped portion 35 by giving the stepped portion 35 to the lower portion thereof. Such a configuration is constituted symmetrically of the link piece 10.

FIG. 2 is another embodiment of FIG. 1.

As shown in the drawing, the lower plate 11 is installed on the plate 3 and the link piece 10 is installed thereon.

1 is different from the structure of the lower plate 11 is installed by digging the link piece 10 in Figure 1, Figure 2 is a link piece 10 is fixed to the upper surface of the lower plate 11 with a pin 12.

An elastic body 15 is provided on the end of the link piece 10. The elastic body 15 can provide a spring, rubber | gum, etc. things. The role of the elastic body 15 is to prevent the breakage caused by frequent contact and a rattling sound at the contact portion of the pressing plate 13 and the link piece 10 by the pressing force when the vehicle passes over the upper plate 1.

3 is an enlarged view illustrating main parts of FIG. 1, and is another embodiment.

The embodiment of FIG. 3 shows that in the embodiment of FIG. 1, the position of the elastic body 15 can be in front of or behind the pin 12 as shown in FIG. 2.

4 is a schematic view for explaining the installation and operation of the link piece 10, with the pressing plate 13 removed.

As shown, the link piece 10 according to the present invention is fixed on one side by a fixing pin 20 coupled to the plate 3, the link piece 10 is pivotable around the fixing pin 20. . The link piece 10 is fixed to the opposite side of the link piece 10 so as to be able to pivot about the pin 12. When both ends of the link piece 10 are fixed, the link piece 10 cannot be folded, so that the lower plate 11 can slide left and right.

If the outside air temperature rises in summer, the tops of the bridges increase, so the ends of the tops of the bridges are narrowed. Then, as the link piece 10 is inclined in the horizontally lying direction in FIG. 5, the gap between the two upper plates may be narrowed. At this time, the lower plate 11 is slid horizontally.

Referring to Fig. 5, the interval indicated by "A" is when the bridge is increased and the top plate is narrowed, and B is the opposite phenomenon. In FIG. 5, the upper end of the link piece 10 has no positional change by the fixing pin 20, but the opposite side of the link piece 10 is fixed by the pin 12, and is moved left and right as the lower plate 11 moves. .

On the other hand, the pressure spring 30 is installed on one side of the lower plate 11 which is slidingly moved.

The reason for installing the pressure spring 30 is as follows.

After the link piece 10 is laid down in the state of FIG. 5 and the two upper plates are narrowed, the distance between the two upper plates is increased because the upper plate contracts when the outside temperature is occupied in winter. The link piece 10 is then unfolded at an angle perpendicular to the lying state.

The lower plate 11 will then move in the " a " direction without the pin 12 rotating and engaging the plate 3. In order to prevent this, the pressing spring 30 is always kept in a pressurized state. Then, since the bottom plate 11 always moves to the side, the force is moved to the side without moving in the "a" direction, and the link piece 10 can be pivoted about the pin 12.

More preferably, there is also a method of providing the protruding jaw 31 at the end of the plate 3 to prevent the lower plate 11 from moving in the "a" direction.

For reference, in FIG. 5, the two top plates are narrowed at an A interval in a form in which the link piece 10 is operated by the moving force of the top plate 1 such that the pressure spring 30 receives a large compressive force. In the widened position of the spring, the spring force of the pressure spring 30 acts on the lower plate 12 in the form of receiving less compressive force due to the opposite phenomenon.

According to the present invention as described above, it is very well adapted to the stretching of the top plate by the link movement of the link piece 10 to accommodate the stretching action, the structure is simple and the operation is accurate.

In addition, by the configuration of the link piece 10 and the elastic body 15 installed in the pressing plate 13 which are installed side by side, there is no noise during the movement of the vehicle, even if there is a partial damage, easy replacement and repair, very convenient in terms of maintenance and maintenance Cost-effective

In addition, since the link piece 10 is installed in a diagonal form in the longitudinal direction and the width direction of the upper plate, the noise is less at the connecting portion of the link piece 10.

In addition, since the link piece 10 of the upper plate is formed at a very gentle angle in the width direction, the operation in the stretching direction is very natural and there is almost no failure.
