Abstract

PURPOSE:To provide a combination mat which can be assembled and disassembled and is convenient for carrying in the mat to be laid on the projecting- recessed ground surface or mud. CONSTITUTION:Holes 6 and claws 5 of mutually adjacent respective mat boards 1 are fitted to each other in a vertically overlapping shape. Since the claws 5 are set below, these claws 5 are pressed down, and the mat boards 1 having these claws 5 are positioned. Since the respective mat boards 1 mutually press down the respective claws 5, these mat boards 1 are positioned. Since to move only one among the respective mat boards 1 is impossible, the whole of this combination mat must be simultaneously moved. Therefore, these mat boards 1 can be reliably positioned as the respective mat boards 1 increase.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combination mat that can be disassembled and carried.

[0002]

2. Description of the Related Art As is well known, at the construction site of a building or a road, the ground is dug up so that the ground becomes uneven.
Mud is also likely to occur. Since such uneven ground and mud obstruct the passage, plywood and iron plates of building materials are often laid on them.

[0003]

However, since these plywood and iron plates are merely scattered appropriately, they are easily misaligned. For passers-by, they often slipped and lacked strength, resulting in unstable walking. Furthermore, these plywood and iron plates are merely diversions of building materials, and are often not suitable size or weight for carrying.

Therefore, an object of the present invention is to provide a mat for laying on uneven ground or mud, which can be assembled and disassembled and is convenient to carry.

[0005]

In order to solve the above-mentioned problems, the combination mat of the present invention comprises a plurality of substantially flat plate-shaped mat boards spread over each other. A downwardly facing concave portion is formed, and the concave and convex portions on the peripheral edges of the mutually adjacent mat disks are vertically overlapped and fitted.

[0006]

According to the present invention, the concave portions and the convex portions of the peripheral edges of the mutually adjacent mat disks are vertically overlapped with each other and are fitted together.
Since the concave portion is on the upper side and the convex portion is on the lower side, the convex portion is pressed down and the mat board having the convex portion is positioned. Since each mat board has both a convex portion and a concave portion, the respective convex portions are pressed against each other to position these mat boards.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of a mat board of the combination mat of the present invention. This mat board 1 is made of polyethylene and has a substantially regular hexagonal shape. One side of this regular hexagon is approximately 60 cm, and the thickness of this mat board 1 is approximately 4 cm.

Although this mat board 1 is hollow, it is lightweight and tough because each concentric rib 2 and each radial rib 3 are formed inside. It weighs several kilograms and can withstand a load of 6 tons.

A large number of small convex pieces 4 are formed on the surface of the mat board 1. These small convex pieces 4 serve as a slip stopper.

Claws 5 facing upward are formed on three sides of the mat board 1, and holes 6 are formed on the other three sides. These claws 5 and holes 6 are alternately arranged on each side of the regular hexagon.

Such a mat board 1 is used as a combination mat formed by laying a plurality of mats as shown in FIG. In this combination mat, as is apparent from FIG. 3, the holes 6 and the claws 5 of the mat disks 1 adjacent to each other are provided.
Are stacked on top of each other and fit together. Since the claw 5 is on the lower side, the claw 5 is pressed and the mat board 1 having the claw 5 is positioned.

Since each mat board 1 presses the claws 5 against each other, the mat boards 1 are positioned. It is impossible to move only one of the mat boards 1, and the whole combination mat must be moved at the same time. Therefore, the more mat boards 1 there are, the more reliably these mat boards 1 can be positioned.

Further, in this combination mat,
One mat board 1 by each of the six surrounding mat boards 1
When the box is surrounded, the central mat board 1 alone cannot be pulled out. Therefore, in order to disassemble this combination mat, each mat board 1 must be sequentially removed from the outer periphery of this combination mat. Therefore, as shown in FIG. 2, one chain 7 is passed through the hole 6 of each mat board 1 on the outer periphery of the combination mat, and this chain 7 is made into a large ring, and both ends of this chain 7 are padlocked (not shown). No)
If it is connected by, the combination mat cannot be disassembled unless the padlock is unlocked. This prevents mischief and theft.

If such a combination mat is laid on the construction site, anyone can pass with peace of mind. When disassembling and collecting this combination mat, the chain 7 is pulled out, and each mat board 1 is sequentially removed from the outer periphery of this combination mat.

Further, as described above, since the load capacity of the mat board 1 is 6 tons, this combination mat can be laid not only on the passage for people but also on the traveling path of the vehicle. In addition, it can be used as an alternative to pavement at event venues and temporary parking lots, setting emergency transportation roads in the event of a disaster, improving snowy roads and bad roads, and reinforcing ridges in tabata. Also, instead of hardening the ground in the warehouse with asphalt or concrete,
By using this combination mat, the cost can be reduced and the construction period can be significantly shortened. Alternatively, if several mats are put on the car, even if the tires of the car are spinning, the mats can be connected and sandwiched between the tires and the ground so that the car can escape. You can

FIG. 4 shows another embodiment of the mat board according to the present invention. The mat board 11 shown in FIG.
Like the mat board 1 of No. 1, it is made of polyethylene and has a substantially regular hexagonal shape. Also, this mat board 11
It is hollow and has concentric ribs and radial ribs formed inside.

Claws 12 facing upward are formed on three sides of the mat board 11, and the concave portions 1 are formed on the other three sides.
3 are formed.

Compared with the mat board 1 of FIG. 1, this mat board 11 has a square periphery and no roundness, and instead of the holes 6 penetrating vertically, the mat board 11 is opened on the lower surface side. The difference is that each recess 13 is closed on the upper surface side.

FIG. 5 shows a state in which each mat board 11 of FIG. 4 is laid. As is clear from FIG. 5, there is no gap between the mat boards 11. This is because the periphery of the mat board 11 is square and each recess 13 is closed on the upper surface side.

By using such a mat board 11, even if a small article is dropped, the small article will not overflow from the gap between the mat boards to the ground and be lost. Therefore, this mat board 11 is suitable for a place where a large number of people gather, such as an event venue or a plaza.

FIG. 6 shows another embodiment of the mat board according to the present invention. The mat board 21 of FIG. 6 is made of aluminum and has a substantially regular hexagonal shape. Since the mat board 21 is made of aluminum, the load capacity thereof is superior to that of the polyethylene board shown in FIGS. 1 and 4, and it can withstand a load of 13 tons. Therefore, this mat board 21 is suitable for paving the road of a vehicle to improve the road.

Claws 22 facing upward are formed on three sides of the mat board 21, and holes 23 are formed on the other three sides.
Are formed.

A non-slip layer 24 is formed on the surface of the mat board 21. This non-slip layer 24 is
A large number of fine particles formed by crushing acrylic resin are adhered to the surface of the mat board 21 with an adhesive.

Further, the mat board 21 is provided with three drain holes 25. These drain holes 25
Is for draining the water contained in the ground onto the mat board 21, which prevents the mat board 21 from rising and slipping.

In each of the above-mentioned embodiments, a regular hexagonal mat board is exemplified, but other shapes may be used. For example, there are regular triangles, squares, diamonds, regular polygons, circles, and the like. In any case, the holes and the claws on the peripheral edges of the mutually adjacent mat plates may be vertically overlapped and fitted. The shapes of these holes and claws can be appropriately changed, and any shape may be used as long as they are convex portions and concave portions that fit with each other.

Further, as the material for the mat board, not only polyethylene and aluminum but also various other synthetic resins and other various metals can be applied.

[0028]

As described above, the combination mat of the present invention is formed by laying a plurality of mat boards, and the mat boards are engaged with each other and pressed against each other to position the combination mat.

By laying this combination mat on uneven ground or mud, anyone can pass with peace of mind. This is just one example, and the applications of this combination mat are numerous.

Further, this combination mat is easy to assemble and disassemble, and by appropriately determining the size and weight of the mat board, it becomes easy to carry, lay and collect the work.
