Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to the edge structure of floor plates for buildings, typified by raised floors.

<Prior Art> FIG. 5 shows an example of a free access floor. A large number of floorboards 1 used here are supported on the floor by support legs 6 from below. Each floorboard 1 is provided with trim edges 4 along the edges of the floorboard panel 2 for finishing the ends of the top and bottom plates of the panel. The material used is ABS resin, hard PVC, etc. If such resin trim edges are not available, the edges of the metal floorboard panels may touch each other.
A metallic sound is generated when walking, etc., giving an unpleasant feeling, and it also causes damage to the edges of panel surface materials such as tiles and melamine decorative boards when installing and removing floorboard panels. Therefore, trim edges play an important role in floorboard panels.

Conventionally, the trim edge 4 has been simply fitted onto the edge of the floorboard panel 2 or fixed using an adhesive or the like.

<Problems that the invention aims to solve> If the trim edge is simply fitted as in the past, it will easily come off, and if adhesive is applied,
At the construction site, it was difficult to apply it evenly within the narrow gap of the trim edge, and sufficient adhesion was not obtained, resulting in the problem that it could easily come off due to impact, etc.

<Means for solving the problem> Therefore, in the present invention, at least one locking recess 3 is provided along the edge of the floorboard panel 2 on both the front and back surfaces or on one side, and a trim edge covering the panel edge is provided. The structure is such that a locking protrusion 5 is provided at a position corresponding to the locking recess 3 on the panel contact side of No. 4.

The locking recess 3 of the panel 2 referred to here means cutting,
It refers to a recess formed by pressing, roll forming, etc., and includes, for example, a concave groove, a plurality of mortises, and the like. In addition, the locking convex portion 5 is the trim edge 4.
These are protrusions, protrusions, tenons, etc. provided at positions corresponding to the locking recesses 3 on the panel contacting side.

<Function> With such a structure, the locking convex portion 5 of the trim edge 4 locks into the locking recess 3 on the edge of the floorboard panel, and functions to prevent the trim edge from coming off.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view showing an example of a building floor plate according to the present invention, and FIG. 2 is an enlarged sectional view taken along line A-A in FIG. 3 and 4 are cross-sectional views showing other structural examples of the trim edge.

In the building floor board 1 shown in FIG. 1, trim edges 4 having a U-shaped cross section are provided at the four edges of a rectangular floor board panel 2. A soft protruding material 7 is provided on the trim edge 4 to maintain contact between the abutting edges 8 and the mating panel so that no gap is created between the trim edge 4 and the mating panel. This prevents dust from falling, air leakage when air conditioning is done from under the floor, dust from under the floor being sent into the room, and metal reflections from below being visible depending on the viewing angle, improving sealing performance. In addition, when walking on the floorboards, it is possible to prevent the floorboards from rubbing against each other and causing abnormal noise.

Projections are provided as locking convex portions 5 on the panel contact sides above and below such trim edges 4. This protrusion is provided at a position corresponding to a concave groove as a locking recess 3 provided on the front and back sides of the edge of the panel 2.

As a structure for preventing the trim edge 4 from coming off, it is also good to make the panel fitting side narrower as shown in FIG. Further, the locking convex portions 5 provided on the panel contact side may have a plurality of locking projections 5 on the upper or lower side as shown in FIG.

<Effects of the invention> By adopting the structure of the floorboard for a building as described in detail above, it has become possible to fix the trim edge with one touch, and it has become possible to eliminate the possibility of the trim edge coming off.
