Description

[Technical field]

[0001] The present invention relates to a floor plate structure for use on uneven ground. [Background technology]

[0002] In construction works such as civil engineering works and building works, there are sites where it is necessary to pass through uneven terrain such as uneven ground. When working using a self-propelled vehicle such as heavy machinery used in construction works, it is necessary to move the heavy machinery to the construction site through the uneven terrain, but it has been difficult to drive the heavy machinery on the uneven terrain. Even in such cases, it is necessary to move the heavy machinery to the construction site through the uneven terrain, and the heavy machinery is transported by various methods. One example is a method in which the heavy machinery is disassembled into parts and transported, and the heavy machinery is assembled at the destination where the heavy machinery has passed through the uneven terrain. There is also a method in which an iron plate or the like is placed on the uneven ground as a passageway for the heavy machinery to pass through, and the heavy machinery runs on the iron plate to transport it to the construction site.

[0003] When disassembling heavy machinery and reassembling it at the construction site, the disassembled parts must be carried to the construction site by human labor, and when placing steel plates on uneven ground, steel plates that can withstand the weight of the heavy machinery must be placed on the uneven ground by human labor. These methods place a heavy burden on construction workers in terms of labor and time, and there is a problem at construction sites of how to make it easier to pass through uneven ground. One invention that addresses this problem is the floor plate disclosed in JP 9-3026060 A. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 9-3026060 Summary of the Invention [Problem to be solved by the invention]

[0005] In this invention, one floor plate has a first connecting portion facing upward, a second connecting portion facing downward, a third connecting portion facing upward, and a fourth connecting portion facing downward. The first connecting portion and the second connecting portion are provided on opposing sides. The third connecting portion and the fourth connecting portion are provided on a side adjacent to the side having the first connecting portion and the second connecting portion. The third connecting portion is provided on the second connecting portion side, and the fourth connecting portion is provided on the first connecting portion side. Therefore, by arranging a plurality of floor plates in a staggered pattern, the first connecting portion facing upward and the second connecting portion facing downward are meshed and held, and the third connecting portion facing upward and the fourth connecting portion facing downward are meshed and held. In this way, a plurality of floor plates are joined, and by laying this assembly of floor plates on uneven ground, it is possible to allow heavy machinery to pass through.

[0006] However, although such a method exists as an idea, there are no examples of it being put to practical use at actual construction sites, and the current situation is that heavy machinery is transported to construction sites by passing through uneven terrain in a time-consuming and labor-intensive manner. [Means for solving the problem]

[0007] The present invention has been made in consideration of such problems, and its object is to provide a floor plate structure that can be laid lengthwise and widthwise on uneven ground to allow vehicles to pass through, and that can easily transport heavy machinery to a construction site.

[0008] That is, the present invention is a floor plate structure that can be laid lengthwise and widthwise on uneven ground to allow vehicles to pass through, and includes a plurality of floor plate panels having a planar portion and a plurality of regulating protrusions arranged at equal intervals on the underside of the planar portion, with restraining grooves provided between adjacent regulating protrusions, and rod-shaped connecting members that fit into the restraining grooves of the plurality of floor plate panels and are provided across adjacent floor plate panels to hold the floor plate panels together. Effect of the Invention

[0009] According to the floor plate structure of the present invention, the connecting members are fitted into the restraining grooves of the floor plate panels and are arranged across the adjacent floor plate panels to hold the floor plate panels together. Therefore, by simply arranging the connecting members at regular intervals on uneven ground and arranging the floor plate panels from above the connecting members, a passageway along which vehicles such as heavy machinery can travel can be completed. Therefore, even if there is uneven ground on the way to a construction site, the floor plate structure of the present invention can be installed and heavy machinery can be easily transported.

[0011] The floor plate structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0012] 1 is a diagram showing the floor plate structure 100 as viewed from above. The floor plate structure 100 is used in construction work such as civil engineering and building works, and is laid out on uneven ground. This allows self-propelled vehicles such as heavy machinery to travel on the uneven ground, and the self-propelled vehicles can be transported to the construction site.

[0013] The floor plate structure 100 has a plurality of floor plate panels 200 that are laid on the uneven ground, and a plurality of connecting members 300 that connect the plurality of floor plate panels 200. The floor plate structure 100 is formed by combining a plurality of floor plate panels 200 and a plurality of connecting members 300.

[0014] 2 is a perspective view showing one of the plurality of floor panel 200. The floor panel 200 has a flat surface 210 and a plurality of regulating protrusions 220 provided on the lower surface of the flat surface 210. The flat surface 210 has a contact surface 211 for the wheels of the heavy equipment and a lower surface 212 facing the contact surface 211. There is no limitation on the material of the flat surface 210, and examples thereof include elastically deformable resin. In addition, the flat surface 210 may be treated with an anti-slip treatment such as irregular grooves on the contact surface 211.

[0015] The restricting protrusion 220 is formed in a rod shape with a substantially rectangular cross section, and is screwed (not shown) to the flat surface 210. As shown in Figs. 3 and 4, the restricting protrusion 220 is provided on the lower surface 212 so that the longitudinal direction of the restricting protrusion 220 is along the lateral direction of the flat surface 210. The floor plate panel 200 of this embodiment has four restricting protrusions 220, and each restricting protrusion 220 is provided at equal intervals along the longitudinal surface of the flat surface 210. The longitudinal length of the restricting protrusions 220 is substantially the same as the lateral length of the flat surface 210. The floor plate panel 200 is used with the restricting protrusions 220 facing downward, and a part of the restricting protrusions 220 is in contact with the uneven ground 400 when the floor plate structure 100 is in use.

[0016] Between the regulating protrusions 220, a restraining groove 230 is formed to hold the connecting member 300 described later by sandwiching it between the regulating protrusions 220. The restraining groove 230 is for regulating the position of the connecting member 300, and has a shape substantially identical to the cross section of the connecting member 300. The floor plate panel 200 of this embodiment has four regulating protrusions 220, but as long as the restraining groove 230 of the connecting member 300 can be formed, the number, shape, arrangement interval, etc. of the regulating protrusions 220 can be appropriately designed and changed. For example, as shown in FIG. 5, the regulating protrusions 220, which are substantially rectangular parallelepipeds, are arranged at equal intervals in three columns and four columns. In addition, in the floor plate panel 200 of this embodiment, each regulating protrusion 220 is screwed to the flat portion 210, but the flat portion 210 and the regulating protrusions 220 do not necessarily need to be separate members, and these members may be molded integrally.

[0017] The connecting member 300 is formed with a substantially rectangular cross section, and is arranged on the uneven ground 400 for use. As shown in Figs. 2, 6 and 7, the connecting member 300 is held in a restraining groove 230 formed between the regulating protrusions 220. As shown in Fig. 8, the connecting member 300 is fitted into the restraining groove 230 of the plurality of floor panel 200, and is provided across the adjacent floor panel 200. This allows the connecting member 300 to integrally hold the plurality of floor panel 200, and the movement of the floor panel 200 in a direction perpendicular to the longitudinal direction of the connecting member 300 (the left-right direction on the paper in Fig. 1) is restricted. As shown in the figure, by arranging the plurality of floor panel 200 in a staggered manner, the movement of the floor panel 200 in the longitudinal direction of the connecting member 300 (the up-down direction on the paper in Fig. 1) is restricted. In this way, the floor plate structure 100 can hold each floor plate panel 200 integrally and firmly by offsetting adjacent floor plate panels 200 from each other along the longitudinal direction of the connecting member 300.

[0018] The height A of the connecting member 300 in the fitting direction relative to the restraining groove 230 of the floor panel 200 coincides with the height B of the regulating protrusion 220 relative to the planar portion 210 of the floor panel 200. The connecting member 300 contacts the lower surface 212 of the planar portion 210 and the uneven ground 400 in the use state of the floor plate structure 100. This allows the connecting member 300 to bear the load of heavy equipment traveling on the planar portion 210 via the planar portion 210. In the floor plate structure 100 of this embodiment, the height A of the connecting member 300 and the height B of the regulating protrusion 220 are approximately the same, so that the load of heavy equipment traveling on the planar portion 210 is applied to the regulating protrusion 200 in addition to the connecting member 300. From the viewpoint of the strength of the floor plate structure 100, it is preferable that the height A of the connecting member 300 and the height B of the regulating protrusion 200 are substantially the same, but this is not limiting, and the height A may be at least equal to or greater than the height B. This allows the connecting member 300 to bear the load of heavy machinery.

[0019] Next, a method of using the floor plate structure 100 of this embodiment will be described.

[0020] First, a plurality of connecting members 300 are laid out on the uneven ground 400 at regular intervals. The arrangement interval of each connecting member 300 is approximately the same as the thickness C of the regulating protrusion 220 (left and right direction of the paper surface in FIG. 4). The number and orientation of the connecting members 300 are appropriately adapted according to the condition and size of the uneven ground 400. Next, a plurality of floor plate panels 200 with the regulating protrusion 220 facing downward are arranged from above the connecting member 300 so that each connecting member 300 arranged on the uneven ground 400 is fitted into the restraining groove 230 of the floor plate panel 200. As shown in FIG. 1, the plurality of floor plate panels 200 may be arranged in a staggered pattern and used in combination with a half-sized floor plate panel 200a depending on the situation. As a result, the multiple projections and recesses formed by the multiple connecting members 300 arranged on the uneven ground 400 engage with the regulating protrusions 220 of the floor plate panel 200, completing the floor plate structure 100 laid out on the uneven ground 400. Heavy machinery travels while contacting the flat surface portion 210 of the floor plate panel 200, and the load of the heavy machinery is borne by the regulating protrusions 220 and connecting members 300 of the floor plate panel 200.

[0021] As described above, according to the floor plate structure 100 of the present invention, the connecting members 300 are arranged at regular intervals on the rough ground 400, and a plurality of floor plate panels 200 are arranged from above the connecting members 300, thereby completing a runway for heavy machinery that cannot pass through the rough ground 400 to be able to run on its own. Therefore, by using the floor plate structure 100, a runway for heavy machinery can be easily completed. In addition, since the floor plate panels 200 of the floor plate structure 100 have the regulating protrusions 220 provided at equal intervals on the lower surface 212, the two floor plate panels 200 can be stacked by facing the lower surfaces 212 of the two floor plate panels 200 and making the regulating protrusions 220 of each floor plate panel 200 enter the restraining grooves 230. Therefore, the floor plate structure 100 can save space during transportation, and is also easy to carry to the rough ground. In this way, the floor plate structure 100 allows heavy machinery to travel over the rough ground 400 and allows for efficient transportation, so that the heavy machinery can be easily transported to the construction site.
