DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor plate laid on, for example, a wasteland, a slope, an event site, a vehicle entrance / exit road for a construction site, a temporary road, and the like.

[0002]

2. Description of the Related Art Conventionally, there is a case where a temporary road is installed by laying an iron plate, wood, or the like for a vehicle to pass on a soft place such as a rough terrain or a construction site.

[0003] For example, Japanese Laid-open Utility Model Publication No.
Japanese Unexamined Patent Publication No. 27525 discloses a combination work table with a slope. This worktable has a horizontal base of a square plane and an inclined base as a slope of a rectangular plane. Then, a large number of horizontal bases are connected vertically and horizontally, and an inclined base is connected around the horizontal base group, and adjacent inclined bases are connected together.

A part is formed.

According to the present embodiment configured as described above, each of the slope plates 21 to 24 and the corpus rope plate 25
28 can form a flat square floorboard. And, on the peripheral edge of the floor plate surface, a downward slope 4
1, 72 and 93 are formed, which is convenient for raising and lowering a vehicle or the like. The first to fourth slope plates 21 and 2
4, the first and second connecting portions 32, 33
One of the corresponding connecting portions 12 and 13 is fitted. At this time, each of the slope plates 21 to 24 is connected to the adjacent middle plate 1 at the connecting portions 32 and 33 on the adjacent two or three sides.
The first and second connecting portions 12 and 13 are alternately fitted from above and below. Therefore, even when a vehicle or the like enters or exits the slope plates 21 to 24, for example, even when the vehicle is deformed, a step is not generated in the connecting portion, and the connecting portion does not come off. In this case, the first and the second connected to each other
Since the contact surfaces of the connecting portions 12, 13, 32, and 33 have an arc shape, concentrated stress and unreasonable force are not generated in the connecting portions, and some movement is allowed.

The first and second slope plates 21 and 22 are fitted into the adjacent slope plates 21 and 22 in the convex portions 38 or the concave portions 39 on both sides 31c and 31d in an uneven relationship. Further, the third and fourth slope plates 23 and 24 are fitted to the adjacent middle plate 11 at the concave portion 73 and the convex portion 81 of the inclined surface portion 72. Therefore, each slope plate 21-2
4 can be prevented from shifting.

The slope plates 21 to 28 are reliably connected to each other by U-shaped connecting pins 48. Both ends of the connecting pin 48 are further driven into the laying ground to make the connection between the slope plates 21 to 28 more reliable.
Further, the connecting hole 47 through which the connecting pin 48 is inserted is an elongated hole, so that the connecting positional relationship between the adjacent slope plates 21 to 28 can be finely adjusted. Further, fixing holes 4
The stake 44 inserted into 5 is driven into the laying ground, and the slope plates 21 to 28 are securely fixed. As described above, the floor surface does not shift when the vehicle or the like enters or leaves the floor surface.

In particular, in this floor plate, the connecting line between the group of middle plates 11 and the slope plates 21 to 24 is not a straight line but a staggered triangle or trapezoid. Therefore, it is possible to suppress the formation of a step due to the weight of the vehicle or the like. For this reason, breakage of the middle plate 11 and detachment of the middle plate 11 and the slope plates 21 to 24 can be reliably prevented.

The anti-slip projection 42 projecting over substantially the entire upper surface of each of the slope plates 21 to 24 has a substantially cross shape pointing in four directions. For this reason, there is a slip prevention function in all directions, and the wheels do not slip when the vehicle or the like travels in any direction. Further, the anti-skid ridge 43 protruding in the vicinity of the riding end in parallel with the riding end prevents slipping of the wheel at the time of riding, and facilitates riding of the vehicle or the like.

On the back surface of each slope plate 21-28, each rib 51-
Because of the provision of 58, the overall strength is excellent, and even if a load of a heavy object such as a vehicle is applied, there is no breakage. Moreover, since the outer ribs 59 and the lattice ribs 60 are provided on the back surfaces of the first and second connecting portions 32 and 33, the strength reduction near the connecting portions 32 and 33 can be compensated. And since the strength was ensured by the ribs 51 to 60 in this way, the weight can be reduced and the handling in transportation or the like becomes easy as compared with the case where the plate body is thickened.

The ribs 51 to 58 are connected to each other, so that the load acting on the upper surface of the plate body 31, ie, the stress, can be distributed along the ribs 51 to 58. Furthermore, the linear radiation rib 57 and the annular ribs 51
53, and the strength of the rib itself is also improved.

In addition, a space having a height h is formed between the lower end surfaces of the ribs 52 to 58 and the laying ground. Therefore, the plate main body 31 is elastically deformed by the height h with respect to the load from above, and can absorb the load. In addition, even when the laid ground is in an uneven state such as a rough terrain, the laid ground can be laid without being largely influenced by the unevenness of the laid ground. Therefore,
In combination with the operation of the ribs 51 to 60, not only the load resistance of the slope plates 21 to 28 is further improved, but also the peripheral edges of the slope plates 21 to 28 are not partially lifted. (Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS. 17 to 22, focusing on parts different from the first embodiment.
