In order to achieve the above object, according to the present invention, a floor plate having a non-slip function has a plurality of holes formed on a surface thereof, and a peripheral portion of each of the holes has a peripheral portion. A plurality of anti-slip claw portions arranged at intervals in the direction are formed so as to be bent upright on the surface side.

[0008] In this floor plate material, mud, dust, snow, rainwater, and the like that have accumulated on the surface fall through a plurality of holes formed on the surface and are discharged. As a result, the problem that mud, dust, snow, rainwater, and the like accumulate on the surface of the floorboard material and make it slippery can be solved. Furthermore, since the plurality of anti-slip claw portions bent at the peripheral portion of each hole are arranged at intervals in the circumferential direction, both in the length direction and the width direction of the floor plate material. It can exhibit the anti-slip effect. In addition, by forming these claw pieces in a complicated shape, the anti-slipping action can be easily improved, so that even a slippery environment such as a snowy or rainy weather can be used for an object such as a loaded vehicle or a worker. Can surely stop slipping.

According to the method for manufacturing a floorboard having a non-slip function according to the present invention, a lower surface having a plurality of anti-slip claw portions which are arranged on a surface at a peripheral edge of the floor plate at intervals in a circumferential direction and protrude inward. After the hole is formed, the claw piece is bent upright to the front side by performing burring on the prepared hole.

In this method of manufacturing floorboards, since the pilot hole on which burring is performed has a plurality of anti-slip claw portions projecting inward at the peripheral edge thereof in advance, the pilot hole is formed by By performing the burring process, a plurality of claw pieces bent upward in the front surface side can be efficiently formed. Further, by processing the peripheral edge of the pilot hole into a complicated shape in advance, a nail piece having a complicated shape can be easily formed.

[0011] In the above-mentioned method of manufacturing a floor board,
It is preferable that the hole is formed by punching using a punch in which a concave portion for forming each of the claw pieces is formed on the outer peripheral surface of the tip.

In this case, the claw piece can be efficiently formed on the periphery of the prepared hole.

[0013]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 to FIG. 3 show a floor panel having an anti-slip function according to an embodiment of the present invention.

This floor plate (1) is used as a guide plate provided in a vehicle carrier, and has a predetermined length and a predetermined width as shown in FIGS. 1 (a) and 1 (b). Aluminum (including its alloys, the same applies hereinafter) plate. In this floor plate material (1), the length dimension is set, for example, in the range of 1500 to 2500 mm, the width dimension is set, for example, in the range of 500 to 800 mm, and the wall thickness is set, for example, in the range of 3 to 6 mm. The material is, for example, A5083-H32.

On the surface of the floor plate (1), a large number of oval through holes (2) are formed. These holes (2) are arranged in the length direction of the floor plate (1) and arranged in four rows in the width direction.

At the periphery of each hole (2), FIG.
