Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to a floor for laying on an exposed floor of a concrete building to form a floor base, or in a room in which a computer room or office automation equipment is installed. The present invention relates to a unit type floor panel that is easily installed to reinforce the floor by laying it and to form wiring grooves for power lines, telephone lines, information signal lines, etc. for each device.

[0002]

2. Description of the Related Art A floor in which a rectangular unit floor panel having a stepped portion at the upper end of the peripheral edge is laid on the floor, and electric wires are passed through a groove formed by facing the stepped portions. A structure (Japanese Utility Model Publication No. 54-39304) is known.

In addition, when laying square unit floor panels on the floor, a floor structure is constructed in which a groove lid / spacer plate is placed between the abutting portions of the four panels and adjacent panels while positioning the panels relative to each other ( 62
-38024) is also known.

[0004]

The above-mentioned known unit floor panel is easy to install because it only needs to be laid on the existing floor or the foundation floor. However, if the construction floor area is large, the above-mentioned unit panel can be used. Even if the floor is lined with stains to define a laying line and each panel is fixed with double-sided adhesive tape or the like, the positions of the panels will shift from each other near the end. Also, it may shift due to the placement of heavy objects.

In the case of the latter panel which is laid while placing a spacer plate, the mutual positions of the panels are determined, but the spacer plate also serves as a lid for the wiring groove, so that the wiring work following the panel construction is performed. Is troublesome because the spacer plate must be removed. Laying the panel while mounting the spacer plate, which is a separate member from the panel, is also a very complicated work.

[0006]

SUMMARY OF THE INVENTION The present invention provides a unit floor panel which is easy to construct and in which the positions of the panels are correctly determined by simply laying the unit floor panels in order without using a separate member such as a spacer plate. For the purpose of obtaining, the panel main body is configured as a hollow or solid with a smooth upper surface and side surfaces, and the flange portion is projected outward to the lower end of the side surface of the panel main body or slightly above it. A concave-convex engaging portion for mutual positioning with an adjacent unit floor panel is formed on an edge of the flange portion.

[0007]

When the unit floor panel of the present invention is laid on the floor, the concave and convex engaging portions of the adjacent unit floor panels are engaged with each other while the concave and convex engaging portions are engaged with each other. Positioning is fixed through the joint so that it does not shift.
