Abstract

PROBLEM TO BE SOLVED: To provide a floor covering for an evacuation center which is strong against a load in a vertical direction with respect to a surface and can be provided at low cost. SOLUTION: A large number of substantially strip-shaped corrugated cardboard pieces 5 are arranged side by side between an upper corrugated cardboard sheet and a lower corrugated cardboard sheet 3 formed in a substantially square shape in a plan view, and each corrugated cardboard piece is arranged in an upright state. The side surface is fixed to the side surface of another adjacent corrugated cardboard piece, the upper edge of each corrugated cardboard piece is fixed to the upper corrugated cardboard sheet, the lower edge of each corrugated cardboard piece is fixed to the lower corrugated cardboard sheet, and the lower corrugated board sheet. The evacuation shelter floor rug is characterized in that each side of the evacuation shelter floor rug is provided with connecting means 7 for separably connecting to the lower corrugated cardboard sheet in the other evacuation shelter floor rug.

Description

  The present invention relates to floor coverings for evacuation shelters, and in particular, to floor coverings for evacuation shelters that are laid on the floor of shelters such as gymnasiums for temporary evacuation in the event of an earthquake, tsunami, typhoon, or fire. Is.

  As a floor covering for an evacuation shelter, a blanket, a plate-like body formed by laminating a plurality of cardboard sheets, and the like are used.

However, since blankets are expensive, they are not necessarily suitable for spreading a large number of blankets on the floor of a large shelter such as a gymnasium.

On the other hand, although a plate-like body formed by laminating a plurality of corrugated cardboard sheets is inexpensive, it is weak against a load in a direction perpendicular to the surface of the plate-like body, so that dents are easily formed on the surface. A plate-like body with dents on the surface is uncomfortable for a user who lives on the plate-like body.

In view of the circumstances as described above, the present invention has been made to provide a floor covering for an evacuation shelter that is strong against a load in the vertical direction with respect to the surface and can be provided at a low cost.

In order to solve the above problems, the present invention provides the following refuge floor coverings.

(1) Between each of the upper and lower cardboard sheets formed in a substantially square shape in plan view, a plurality of substantially strip-shaped cardboard pieces are juxtaposed, and the side surfaces of the cardboard pieces are adjacent to each other. Fixed to the side surface of the other cardboard piece, the upper edge of each cardboard piece is fixed to the upper cardboard sheet, the lower edge of each cardboard piece is fixed to the lower cardboard sheet, and each side of the lower cardboard sheet The refuge floor covering is provided with a connecting means for detachably connecting to a lower cardboard sheet in another refuge floor covering (Claim 1).

(2) As the connecting means, convex portions are formed on two sides of the lower cardboard sheet, and concave portions corresponding to the convex portions are formed on the other two sides of the lower cardboard sheet. Item 2).

[Convention of claim 1]
In the invention of claim 1, between the upper cardboard sheet and the lower cardboard sheet, a plurality of substantially strip-shaped cardboard pieces are juxtaposed in parallel, and the side surface of each cardboard piece is adjacent to another corrugated cardboard. The floor for an evacuation shelter according to claim 1, wherein the corrugated cardboard piece is fixed to the side surface, the upper edge of each corrugated cardboard piece is fixed to the upper cardboard sheet, and the lower edge of each cardboard piece is fixed to the lower cardboard sheet. The rug is extremely rugged and resistant to loads perpendicular to the surface. Therefore, there is no risk of dents on the surface. In addition, each side of the lower cardboard sheet is provided with a connecting means for detachably connecting to the lower cardboard sheet in other evacuation floor coverings, so by connecting a large number of shelter floor coverings A wide sheet can be formed. Furthermore, since the floor covering for an evacuation shelter is formed only of cardboard, it can be provided not only at a very low price, but also can be recycled after use.

[Convention of claim 2]
As a means for connecting the floor coverings for evacuation shelters, convex portions are formed on two sides of the lower cardboard sheet, and concave portions corresponding to the convex portions are formed on the other two sides of the lower cardboard sheet. Therefore, the refuge floor coverings can be connected to each other very easily by fitting the convex portions into the corresponding concave portions of the lower corrugated cardboard sheet in the other refuge floor coverings. Moreover, the floor covering for a refuge can be separated very easily by removing the convex portion from the corresponding concave portion.

FIG. 1 is a bottom view showing a connected state of a plurality of shelter floor coverings according to the present invention. FIG. 2 is a plan view showing a part of the upper corrugated cardboard sheet in the above refuge floor covering. FIG. 3 is a front view of the refuge floor covering. FIG. 4 is a perspective view showing a substantially strip-shaped cardboard piece in an upright state. FIG. 5 is a front view showing a substantially strip-shaped cardboard piece in an upright state.

  Between the upper cardboard sheet 1 and the lower cardboard sheet 3 formed in a substantially square shape in plan view, a plurality of substantially strip-shaped cardboard pieces 5, 5.

As an example, the upper corrugated cardboard sheet 1 and the lower corrugated cardboard sheet 3 are made of double-sided corrugated board in which a core is fixed between the liner and the liner, respectively.

The substantially strip-shaped cardboard piece 5 is formed by cutting a cardboard such as a double-sided cardboard, a double-sided cardboard, and a double-sided cardboard into a substantially strip shape. As shown in FIGS. 4 and 5, the “upright state” of the corrugated cardboard piece 5 means a state in which the corrugated board piece 5 is disposed horizontally so that the side surfaces 5 a and 5 b of the corrugated cardboard piece 5 are vertical.

The side surfaces 5 a and 5 b of each cardboard piece 5 are fixed to the side surfaces 5 a and 5 b of the other adjacent cardboard pieces 5, the upper edge 5 c of each cardboard piece 5 is fixed to the upper cardboard sheet 1, and the lower edge of each cardboard piece 5 5 d is fixed to the lower cardboard sheet 3.

Each side of the lower cardboard sheet 3 is provided with connecting means 7 for detachably connecting to the lower cardboard sheet 3 in another refuge floor covering.

As the connecting means 7, for example, convex portions 7 a are formed on two sides of the lower cardboard sheet 3, and concave portions 7 b corresponding to the convex portions 7 a are formed on the other two sides of the lower cardboard sheet 3. Form. In the example shown in FIG. 1, each convex part 7a and each concave part 7b are each formed in the substantially trapezoid shape in planar view.

Claims (2)

Between the upper cardboard sheet and the lower cardboard sheet each formed in a substantially square shape in plan view, a plurality of substantially strip-shaped cardboard pieces are laid in parallel, and the side surfaces of each cardboard piece are adjacent to each other. Adhering to the side surface of the cardboard piece, the upper edge of each cardboard piece is fixed to the upper cardboard sheet, the lower edge of each cardboard piece is fixed to the lower cardboard sheet, and the other side of the lower cardboard sheet is other A refuge floor covering comprising a connecting means for detachably connecting to a lower corrugated cardboard sheet in the refuge floor covering.   As the connecting means, convex portions are formed on two sides of the lower cardboard sheet, and concave portions corresponding to the convex portions are formed on the other two sides of the lower cardboard sheet. The floor covering for an evacuation shelter according to claim 1.
