Description

Description: TECHNICAL FIELD The present invention relates to a fastening method for laminating a long, rectangular ceramic plate on a wooden base of a building.

[Conventional technology]

Conventionally, as shown in FIGS. 14 (a) and (b), a long wooden piece,
The rectangular plate material 1 is arranged in the horizontal direction, the lower edge of the upper plate material is overlapped with the upper edge of the lower plate material, and the outer wall is attached to the wooden base 2 in order from below to above. Is widely used. However, recently, in order to prevent the spread of fire and the like in buildings, ceramic-based non-combustible plate bodies have come to be used instead of wooden plate materials when armoring is performed.

In the case where the ceramic base plate is used for the wooden base 2 to be tensioned, as shown in FIG. 15, a notch 4 is provided along the edge at the top of the long side of the plate 3, and FIG. As shown in (b), the notch 4 is engaged with the upper surface of the lower plate body 3 ′ or the lower rear surface of the upper plate body 3 ″, and is fastened to the base by nails or screws 5.

[Problems to be solved by the invention]

However, according to this method, not only the thickness of the upper and lower plate bodies 3 ', 3 "superposed on each other becomes thin, resulting in poor design, but also the strength of the cutout 4 is reduced. There was a defect that the heads of the nails, screws 5, etc. appeared on the surface and spoiled the appearance.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an armored fastening method that can be easily and strongly attached to a wooden base and that the heads of nails, screws 5, etc. do not appear on the surface. .

(Means for Solving Problems) The present invention has been made to achieve the above object, and the gist thereof is as follows.
A long and rectangular plate made of ceramic material is set in the horizontal direction, the lower edge of the upper plate is overlapped with the upper edge of the lower plate on the wooden base of the building, and it is attached from top to bottom. In the fastening method, at least in the vicinity of one longitudinal edge which is the lower edge of the plate, a through hole penetrating the plate parallel to the edge is provided, and the through hole and the plate are provided on the back surface near the edge of the plate. A hook metal fitting having a hook portion is attached by a stopper inserted between the back surface and the armor plate, and the upper edge of the lower armor plate is engaged by using this armor plate. There is an armoring fastening method in which a holding metal fitting having a joint portion is attached to a base and held, and the hooking portion of the hooking metal fitting of the upper armoring plate is hooked on the engaging portion of the above-mentioned holding metal fitting to armor.

[Specific Structure and Action of Invention]

 The method of the present invention will be described below with reference to the drawings.

In the method of the present invention, as shown in FIG. 1, a plate body 12 having one or a plurality of through holes 11 parallel to an edge is used in the vicinity of one longitudinal edge of a long and rectangular shape. However, as shown in FIG. 2, a ceramic-based outer wall plate made by extrusion molding of cement mortar or the like generally has a large number of through holes 11 in the longitudinal direction in order to reduce its weight and improve heat insulation. …
However, it is needless to say that such a hollow molded plate body can be used in the method of the present invention.

3 (a) and 3 (b) show an example of the armoring plate 13 used in the method of the present invention, in which reference numeral 14 is a plate.
It is a hook fitting to be attached to 12. The hooking metal fitting 14 is composed of a flat plate portion 16 having a stop hole 15 that is locked to the back surface of the plate body, and a hooking portion 17 that is hooked to an engaging portion of a holding metal fitting described later,
On the back surface of the plate body 12, the stop hole 15 and the back surface of the plate body 12,
It is fixed by a stopper 18 that is inserted through the through hole 11.
An armoring plate 13 is formed. The stopper 18 may be anything that can firmly fix the hooking metal fitting 14, but in particular, the thread cutting screw 18a blind blind 18b
Etc. are suitable.

Further, in order to further firmly fix the hooking metal fitting 14 to the plate body 12, as shown in FIG. 4, a reinforcing member 19 having a U-shaped cross section is inserted into the through hole 11 and fixed by a thread cutting screw 18a. Alternatively, as shown in FIGS. 5 (a), (b) and FIG. 6, the stopper hole of the flat plate portion 16 of the hooking metal fitting 14 is an elongated hole 20, and the stopper insertion hole 21a is formed on the surface of the flat plate portion 16. It is also possible to fix the plate-shaped reinforcing member 21 that has been drilled by the blind blindpet 18b. In addition, as shown in FIG.
The fixing force may be increased by increasing the wall thickness t between the back surface of the and the through hole 11. As a matter of course, the method of increasing the fixing force may be used alone, or may be used in combination. Further, as shown in FIG. 8, in the factory, a flat plate reinforcing member 22 may be previously attached to the back surface of the plate body 12 with respect to the through hole 11, and the hooking metal fitting 14 may be attached on site. The reinforcing material is usually made of metal, synthetic resin, or the like.

Further, the shape of the holding metal fitting for hooking the hook metal fitting 14 of the armoring plate body 13 differs depending on the type of the hook metal fitting 14 used.

As shown in FIG. 9, the holding metal fitting 31 for hooking the hooking metal fitting 14 described above holds the holding portion 32 for holding the wooden base 2, and the holding portion 33 for holding the upper edge of the lower armoring plate 13 '. , And an engaging portion 34 for hooking the hooking portion 17 of the upper armoring plate 14
It is composed by.

In order to carry out armoring using the above-mentioned holding metal fittings 31 and armoring plate body 13, as shown in FIG. After holding and fixing the locking portion 32 to the wooden base 2 with the screw 35, the hooking portion 17 of the upper armoring plate 14 is hooked on the engaging portion 34. Then, the upper edge of the upper armoring plate 13 ″ is held down by the metal fitting 31. By repeating this, the tensioning work can be done easily. 36 is a sealing material for preventing intrusion of rainwater and the like. .

Further, FIGS. 11 to 13 (a) and (b) are views showing other examples of the armoring plate body 13 and the holding metal fitting 31 used in the method of the present invention, and the same parts are designated by the same reference numerals. The description thereof will be omitted, and the same reference numerals will be used for the same functional parts of each metal fitting.

The engaging portion 34 of the retainer fitting 31 shown in FIG. 11 is formed by protruding a part of the retainer portion 33 upward, and the upper armor tensioning plate body 13 'is formed.
The hook portion 17 of the hook metal fitting 14 is bent upward at the boundary with the flat plate portion 16 and can be easily hooked to the engaging portion 34.

The holding metal fitting 31 shown in FIGS. 12 (a) and 12 (b) has a locking portion 32 and an engaging portion 34 integrated with each other, and the upper surface thereof is open to form a bag shape. Following the flat plate portion 16, the tip of the hooking portion 17 of the hooking metal fitting 14 having a crank-shaped bent cross section is inserted into this opening. .

FIGS. 13 (a) and 13 (b) have substantially the same structure as FIGS. 12 (a) and 12 (b), but the screw 35 does not pass through the plate body. In this case, a hollow molded plate was used as the plate,
Even if other metal fittings are used, the hollow molded plate body can be used for armoring.

〔effect〕

As described above, the armoring fastening method of the present invention is
Economical construction is possible without requiring labor and time, and each member such as metal fittings and fasteners that are used does not appear on the surface, and it can be fastened without reducing the thickness of the overlapping parts. Therefore, it is a very excellent construction method with many advantages such as good appearance.
