Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a partition wall on a double floor formed by supporting and arranging a number of rectangular floor panels at a constant height on the floor base of a building room. The present invention relates to a locking metal fitting used to fix a floor rail member, which fits and supports a lower end edge of the partition wall when the wall is erected, to a floor panel surface.

[Conventional technology]

It is generally practiced to form a double floor by adjoining a large number of rectangular floor panels adjacent to each other through supporting metal fittings on the floor material. A method is adopted in which a C-channel type floor rail is extendedly fixed on the floor surface, and the lower edge of the partition wall is fitted and supported by this floor rail.

As means for extending and fixing the floor rail to the double floor surface, a method of directly screwing to the floor panel surface, or an anchor bolt erected on the floor ground through a notch usually provided on the side edge of the floor panel By means of a screw member directly or indirectly via a lid member or the like fitted in the cutout portion and fixed by the anchor bolt (for example, Japanese Utility Model Publication No. 1-61
No. 338) is used.

[Problems to be solved by the device]

The partition is to change the installation position so as to adapt to changes in the usage conditions of the room.Therefore, in the method of fixing the floor rail directly to the double floor panel surface by screws, the floor panel surface is screwed by changing the position. There is a problem that the screw holes remain and the strength of the floor panel deteriorates, and the service life is shortened.With the method of erected the anchor bolt on the floor base, it is necessary to embed the anchor nut each time. Not only that, there is a problem that bolt holes are formed in the cutout lid of the floor panel and the floor rail surface, and the work of aligning them is very troublesome.

[Means for Solving the Problems]

The present invention is a metal fitting that can easily and easily fix a floor rail by screwing it by fitting it into a notch that is usually formed on the side edge of a floor panel for forming a double floor. This solves the problem of the floor rail fixing means.

That is, the present invention is a metal plate metal fitting formed with upper and lower plate pieces that are bent at right angles from the upper and lower edges of the side wall and face each other in parallel, and the upper plate pieces are notches on the side edges of the floor panel. A size that can be fitted into the recessed step provided on the upper peripheral edge of the section, a size that the lower plate piece can engage with the lower surface of the floor panel at the peripheral edge of the cutout,
The gist of the partition locking fitting for a double floor is characterized in that the side wall has a size capable of fitting and fitting into the opening width of the cutout portion.

As floor panels for double floors, square plates with a side of 50 to 90 cm, such as metal, synthetic resin, concrete, and wood, are mainly used. Usually, a rectangular cutout is provided at the center of the opposite side edge. Is used as a handhold for handling, and as an underfloor communication port when a double floor is formed, such as wiring and piping outlets.

The notch provided on the side edge of the floor panel is usually recessed along the upper surface of the peripheral edge in order to engage the edge of a fitting such as a wiring pipe or to fit and engage the lid plate flush with the floor surface. A step is formed.

The metal fitting of the present invention is fitted into the cutout portion of the floor panel for a double floor from the side surface of the floor panel, so that the upper plate side of the metal fitting fits and engages with the upper surface of the concave step portion of the upper peripheral edge of the cutout portion. ,
The lower plate piece engages with the lower peripheral edge of the cutout portion, and the side wall fits and fits into the cutout opening so that its outer surface is substantially flush with the side surface of the floor panel. By arranging at the required location of the double floor, the metal fitting is irremovably upward from the floor surface and is prevented from moving in the surface direction and is held firmly and stably, and is located on the upper plate piece of the metal fitting and is a partition. A partition wall can be easily formed by placing a floor rail, fixing it with screws, and fixing it with tapping screws.

Therefore, the upper plate piece and the lower plate piece of the metal fitting of the present invention face each other in parallel with each other at a distance slightly larger than the floor panel thickness of the cutout portion of the floor panel, and the front edge and both side edges of the upper plate piece are recessed in the cutout portion. The size is preferably such that it can be brought into contact with the peripheral side wall of the stepped portion, but the front edge of the upper plate piece is bent downward to make the width of the hanging piece equal to the opening width of the notch, and the front surface of the hanging piece is notched. It may be possible to make contact with the front wall surface of the part, and by doing so, it is possible to increase the strength of the metal fitting and prevent the metal fitting from tilting upward, and the lower plate piece is attached to the lower surface of the floor panel around the notch. It is preferable that the metal fittings come into contact with each other, but the metal fittings that can engage at least the lower surfaces on both sides of the cutout portion can prevent the metal fitting from being detached upward.

[Action]

The metal fitting of the present invention is fitted to the side edge cutout portion of the floor panel before laying, and the double floor formation prevents the metal fitting from being disengaged in the upward direction and moves in the plane direction, thereby forming a stable and firm floor rail fixing surface. The floor rail can be easily fixed by screwing a tapping screw from the top surface, or by drilling or screwing.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a locking metal fitting of the present invention, and FIG. 2 is a perspective view of a notch formed in a side edge of a floor panel into which the locking metal fitting is fitted.

The notch C formed on the side edge of the floor panel P has a rectangular shape having an opening width A and a depth B, and a concave step D having a predetermined width is provided on the upper peripheral edge thereof, and the width A ′ and the depth B are provided. It forms a rectangle of '. H is the floor panel thickness, and H'is the panel thickness of the concave step portion D.

The locking metal fitting is a steel plate molded product in which an upper plate piece 1 and a lower plate piece 3 each bent at a right angle from the upper and lower edges of the side plate 2 are opposed to each other.
