Description

  The present invention relates to a gap cover device for closing a gap generated when plates are arranged, and more particularly to a cover device suitable for closing a gap of a lining plate used in road works or the like.

  In places where the ground has been excavated by civil engineering work or the like, a lining plate made of a steel plate is laid to secure traffic temporarily in order to ensure traffic. The lining plate on which the expansion / contraction device cannot be installed has a structure that leaves a gap of about 2 cm, and this gap is dispersed by bending due to the passage of the vehicle or temperature change, but the gap may expand without being dispersed.

  For this reason, accidents may occur when footwear or tires of passing vehicles are caught between passers-by. Women's heels and bicycles with narrow tires are particularly at risk, and bicycles run at a speed of around 20 km / hr and have no means of protecting the driver from external impacts. Because they are equal, a fall can lead to a major accident. Similarly, the number of wheelchair users with narrow tire widths tends to increase with the aging of the population, and some measures are necessary.

  As a conventional countermeasure, a member or a resin agent is filled in the gap of the lining plate to fill the gap. However, when the gap is further expanded, the gap is exposed. In addition, the above-mentioned first-aid treatment makes a difference in quality depending on the skill of the installer. Moreover, the lining plate has standards of each manufacturer, and the actual situation is that the depth of the gap does not correspond to the difference.

  Patent Document 1 discloses a hole closing cap for a cover plate composed of a flat lid portion in which a metal plate is embedded and a locking portion having flexibility. There is room for improvement in that it cannot cope with differences in standards. Furthermore, Patent Document 2 discloses a spacer for a lining board having a main body that increases in the gap width direction when the dimension in the lining board thickness direction is reduced, and an adjustment member that adjusts the thickness direction dimension of the main body. However, in this case, there is room for improvement in workability of attaching / detaching to the gap of the lining plate.

  Accordingly, an object of the present invention is to provide a gap cover device that can cope with a difference in standards such as the thickness of a lining plate in a certain range, can also deal with a change in a gap in a certain range, and is easy to attach and detach. There is.

  The present invention has been made as a result of various investigations on the structure of the gap cover, which is different from the method disclosed in the above-mentioned prior art document, in the method of locking to the lining plate.

  That is, the present invention includes a plate-shaped cover, a gap plate that is attached substantially perpendicularly to the cover, a columnar member that is provided to extend in the same direction as the gap plate, and the cover of the columnar member. A height adjusting plate joined to form an almost same surface as the gap plate in a state where the mounting position can be adjusted within a certain range at the end opposite to the side, and substantially perpendicular to the cover In the direction, it is inserted in a through hole provided in the height adjustment plate in a rotatable state, has a means for pressing against the cover side, and a means for rotating from the outside is provided at the end on the cover side. And a recess that can be fitted to the height adjustment plate in a state of being joined to the other end of the shaft and rotated substantially perpendicular to the height adjustment plate. And having a rotating hook plate that is a gap cover device.

  Further, in the present invention, the gap is characterized in that a through hole for inserting a device for rotating the shaft is provided in a portion of the cover that intersects with an extension line of the shaft. Cover device.

  In the gap cover of the present invention, since the plate-like cover having a certain width is integrally joined in the vertical direction of the gap plate for filling the gap, even if the gap of the lining plate is widened, Thus, the gap is not exposed and road safety can be ensured.

  In addition, since it is structured to lock on the ground side of the lining plate using a rotating hook, the fact that no protrusion is formed on the road surface side can contribute to ensuring safety on the road surface and the rotating hook from the road surface side. Since the structure can be moved, attachment / detachment work to / from the lining plate becomes extremely easy. In addition, since the pivot hook has a structure arranged via a height adjustment plate whose mounting position can be adjusted within a certain range, it can be used for lining plates of various standards.

  The perspective view which shows an example of the clearance gap cover apparatus which concerns on this invention.   The figure which shows the example which installed the clearance gap cover apparatus which concerns on this invention in the clearance gap between lining boards.

  Next, an embodiment of the present invention will be described based on a diagram showing a specific example.

  FIG. 1 is a perspective view showing an example of a gap cover device according to the present invention. In FIG. 1, 1 is a cover, 2 is a cushioning material, 3 is a through hole for inserting a rotating tool, 4 is a gap plate, 5 is a shaft, 6 is a shaft head, 7 is a compression spring receiver, 8 is a compression spring, 9a, 9b is a columnar member, 10 is a height adjusting plate, 11 is a through hole for bolt insertion, 12a and 12b are bolts, 13 is a rotation hook, and 14 is a recess. FIG. 2 is a view showing an example in which the gap cover device according to the present invention is installed in the gap of the lining plate. In FIG. 2, 15 is the lining plate.

  As shown in FIGS. 1 and 2, in the gap cover device according to the present invention, the gap plate 4 is inserted into the gap of the cover plate 15, and the cover 1 closes the gap when the cover plate is laid. Structure. For this reason, even if the gap of the lining plate 15 widens, the gap is not exposed to the road surface unless the width of the gap exceeds the width of the cover. That is, the gap is substantially completely closed.

  Further, in the present invention, the rotating hook 13 is in contact with the ground-side surface of the lining plate, and the rotating hook 13 is connected to the upper end surface of the height adjusting plate 10 when the gap cover device is in use. 1 is pushed upward by the compression spring 8, which is disposed between the compression spring receiver 7 and presses the shaft 5 toward the cover 1, and the recess 14 is fitted to the lower end of the height adjustment plate 10. Fixed. As a result, the state in which the cover 1 is in contact with the surface of the lining plate 15 is secured, and the cover 1 is extremely difficult to be removed from the gap.

  Further, a plurality of female screw holes (not shown) are provided on the left and right end faces of FIG. 1 of the height adjusting plate 10 and are attached via bolt insertion through holes 11 provided in the columnar members 9a and 9b. The height adjustment plate 10 is joined to the columnar members 9a and 9b using bolts 12a and 12b. Therefore, the distance between the height adjustment plate 10 and the cover 1 can be adjusted within a certain range, and the difference in the thickness of the lining plate 15 can be dealt with.

  Then, for example, by providing a hexagonal hole in the shaft head 6, a hexagon wrench is inserted from the through hole 3 for inserting the rotating tool, and the tip of the hexagon wrench is fitted into the hexagonal hole. The rotating hook 13 can be rotated by pushing down the shaft 5 in the downward direction in FIG. 1 against the repulsive force of the compression spring 8. Thereby, the rotation hook 13 can be arranged on the same surface as the height adjustment plate 10, and the gap cover device according to the present invention can be removed from the gap of the cover plate 15.

  When the gap cover device according to the present invention is disposed in the gap of the lining plate 15, an operation opposite to the above may be performed. Of course, the shaft head can be rotated by using an appropriate tool, whether it is provided with the hexagonal hole or a simple groove. In addition, noise and vibration can be suppressed by arranging the cushioning material 2 made of rubber or the like at an appropriate position.

  As described above, according to the present invention, it is possible to provide a device for closing the gap between the lining plates with a relatively simple structure, which contributes to ensuring safe traffic such as a civil engineering work site, It can be said that it is extremely large. Note that, for example, the present invention is not limited to the above-described embodiment so that it can be used to close a gap other than the lining plate if conditions are set, and ordinary knowledge in the field of the present invention. Even if there is a design change within a range that does not depart from the gist of the present invention, including various modifications and corrections that can be conceived by those who have the above, it is obvious that they are included in the present invention.
