Description

[Detailed description of the invention]

[0001]

The present invention relates to a hollow extruded plate,
In particular, the present invention relates to a hollow extruded plate suitable for a case where a plurality of sheets are erected with their side faces abutting each other.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional hollow extruded plate (for example, a cement plate) 1 has a plurality of cavities 2 extending in the extrusion direction (perpendicular to the plane of FIG. 3). The rib 3 is provided perpendicular to the plate surface 1a.

Recently, as shown in FIG. 4, the use of a hollow extruded plate 5 having a rib 4 inclined with respect to the plate surface has been considered. With this hollow extruded plate 5,
A notch 6 is provided so as to communicate the cavity 2 with the outside, and a binding metal fitting 7 is engaged with the notch 6 so that adjacent hollow extrusion molded plates 5 of the same shape can be connected.

[0004]

In the hollow extruded plate 5 shown in FIG. 4, since the notch 6 extends from the upper end to the lower end of the hollow extruded plate 5, the binding metal 7 However, there is a problem that the material slips down to the lower end of the formed plate 5.

[0005]

The hollow extruded plate of the present invention is provided with such a cutout part so that the binding metal does not slip down to the lower end.

That is, the hollow extruded plate of the present invention is provided with a plurality of hollow portions extending in the extrusion direction, and each of the hollow portions is separated by a rib.
The rib near the side edge along the extrusion direction is inclined with respect to the thickness direction of the plate, and the plate surface is partially removed on the side opposite to the side edge with the inclined rib interposed therebetween, whereby the hollow is formed. The present invention is characterized in that an insertion opening of a binding fitting for connecting the extruded plates is formed.

[0007]

A plurality of hollow extrusion-molded plates of the present invention are erected, and the side surfaces of adjacent hollow extrusion-molded plates are abutted to each other and connected by a bind fitting. In this case, the binding fitting is inserted into the insertion opening of the hollow extruded plate.

[0008] When the binding metal is slipped downward, it stops against the lower edge of the insertion opening, so that it does not slip to the lower end.

1 is a perspective view of a main part of a hollow extruded plate according to an embodiment, and FIG. 2 is a horizontal sectional view of the hollow extruded plate (first embodiment).
FIG. 2 is a cross-sectional view taken along a line II-II in FIG.

The hollow extruded plate 8 is provided with a plurality of hollow portions 2. Each cavity 2 has a rib 3 perpendicular to the plate surface.
And a rib 4 inclined with respect to the plate surface.

The rib closest to the side surface of the hollow extruded plate 8 is an inclined rib 4, and a cavity 2 (2a) divided by the rib 4 is provided with an insertion opening 9 for a binding metal. ing. The insertion openings 9 are provided at the upper end and the lower end of the hollow extruded plate 8 in this embodiment. One or a plurality of insertion ports 9 are also provided in the middle part of the vertically formed hollow extrusion molded plate 8 in the height direction. The insertion port 9 in the height direction may be omitted.

In such a hollow extruded plate 8, the first
As shown in the figure, the hollow extruded plates 8 are joined together by abutting the side surfaces of the vertically formed hollow extruded plates, inserting the binding fitting 7 into the insertion opening 9 and hooking the inclined ribs 4. Can be connected. Even if the binding metal 7 slips downward, it hits the lower edge 9a of the insertion opening 9 and does not fall below it. Therefore, the hollow extruded plates 8 can be firmly connected.

In the present invention, the length of the insertion opening 9 in the vertical direction may be about 5 to 10 cm, but it is obvious that it can be appropriately selected according to the size of the binding metal 7.

The insertion opening 9 may be formed at the time of manufacturing the hollow extruded plate, or may be formed at a construction site.

[0015]

[Effect] As described above, when a plurality of hollow extruded plates of the present invention are erected and connected with the binding metal, the binding metal does not slip off, and the connection between the hollow extruded molding plates is stabilized. It will be.
