Abstract

PROBLEM TO BE SOLVED: To provide inorganic molding bodies for allowing the stacking of design structural portions without damages, and provide their stacking method. SOLUTION: Roof materials 11a, 11b as inorganic molding bodies have two design structural portions 12a, 12b and joint locking portions 13 to place other roof materials thereon in construction, respectively. A channel 14 is formed between two design structural portions 12a, 12b and a rib is formed opposite the channel 14 on the opposite face of the channel 14. Protruded portions 16a-16d are formed on the surfaces of the joint locking portions and recess portions are formed opposite the protruded portions on the reverses thereof. When the plurality of roof materials are stacked on each other with the gravity centers designed to be located near the joint locking portions, the opposed roof materials are fitted to each other at their recessed portion and at their protruded portions without abutting the design structural portions 12a, 12b and the channels.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment in which an inorganic molded article of the present invention is used as a roofing material. 1 to 4 show a roof material according to the present embodiment. 1 and 2 are a plan view and a bottom view of such a roofing material. FIGS. 3A, 3B, and 3C are respectively AA line and BB in FIG. FIG. 4 is a cross-sectional view taken along the line CC and the line CC, and FIG. 4 is a cross-sectional view taken along the line EE in FIG. 1.

The roofing materials 11a and 11b are plate-like members made of a fiber-reinforced cement molding made of an inorganic material, in particular, cement, a filler, and reinforcing fibers. A tiled component that has a design, and a joint locking portion that is partially formed around the tiled component and that mounts another roofing material that is adjacent to the roofing material at the time of construction in which a plurality of roofing materials are laid to form a roof 13 is provided. In each of the design components 12a and 12b, the roof material surface side protrudes upward, and the back surface side is concave. On the surface side of the roofing material, a vertically extending groove 14 is formed between the two design components in the width direction. on the other hand,
A rib 15 extending in the vertical direction like the groove 14 and having a reinforcing effect is formed in a portion on the back surface side of the roof material facing the groove 14.

At the time of construction, the joining and locking portions 13 are provided by the design components 12a and 12b so that the height of the surface of the design components on the surface side of the roof material becomes uniform when another adjacent roof material is placed. Are also formed one step lower. A plurality of truncated pyramid-shaped protrusions 16a, 16b, 16
c and 16d are formed. The convex portion 16a extends along the vertical edge 17 of the joining and locking portion, and the convex portions 16c and 16d form the side portions 18 in the width direction of the joining and locking portion.
Extends along. Further, the convex portion 17b is formed at the corner portion 20 of the joint locking portion, and has a L-shaped cross section. On the other hand, on the back surface side of the roofing material of the joint locking portion 13, a plurality of concave portions 21a, 21b having a shape to be fitted with the corresponding convex portions are provided in portions facing the convex portions 16a, 16b, 16c, and 16d. 21c and 21d
Are formed.

Next, the plurality of roofing materials 11a and 11b configured as described above are stored or transported during storage, as shown in FIG.
As shown in the figure, the rear surface of the roof material 11a located relatively above and the surface of the roof material 11b located relatively below face each other, and are stacked substantially vertically.

When stacked in this manner, each recess 2 of the roofing material 11a located above, as best shown in FIGS. 6 (a) and 6 (d) and FIG.
The corresponding convex portions 16a, 16b, 16c and 16d of the roof material 11b below are fitted into 1a, 21b, 21c and 21d. On the other hand, as shown mainly in FIGS. 6 (c) and 7 (a), each of the design components 12b of the lower roof material 11b is replaced with the upper roof material 11b.
a depression 21a on the back surface of the corresponding design component 12a
And does not come into contact with the roof material 11a located above. Further, the rib portion 15 of the roof material 11a above does not abut on the groove 14 of the roof material 11b below. That is, the upper roof material 11b does not come into contact with the design component 12b and the groove portion 14 of the lower roof material 11b in the concave portion 22a, and the lower roof material 11b
Are supported by the convex portions 16a to 16d.

Further, the roof material 11a located above is designed such that the position 25 of the center of gravity is designed closer to the joining and locking portion 13 than the apparent center of gravity 24 on the diagonal line of the tile constituting portion.
Without being supported by 2a and the groove 14, the recesses 21a to 21d of the roof material 11a above and the projections 16a to 16d of the roof material 11b below are all fitted, and each of the roof materials 11b below Design component 12b and groove 14
There is no contact with.

Therefore, the roofing material 11a of this embodiment,
11b, when stacked, each roofing material 11
The roof components a and 11b do not come into contact with the opposing roofing material, the projections 16a to 16d and the recesses 21a to 21d are fitted, and the roofing material is displaced vertically in the width direction and the vertical direction. Is prevented, each roofing material 11a, 1
The design components 12a, 12b and the groove 14 of FIG. 1b are prevented from being damaged.

The inorganic molded article of the present invention is not limited to the above-described embodiment, and only one design component of the roofing material may be formed, or three or more design components may be formed. It may be.

Further, the inorganic molded article of the present invention can be applied not only to a roof material but also to a wall material or a floor material of a structure, and can be widely applied to ceramic building materials.
Further, a surface treatment layer such as a coating treatment layer or a cosmetic treatment layer may be formed on at least one of the front surface and the back surface. In this case, the coating layer may be formed by simply applying an inorganic or organic coating material to the surface and curing it by a spray gun or the like, but preferably improves the smoothness and the adhesion of the coating film. For the purpose of this, it is preferable to form a layer by applying an inorganic or organic paint after performing a base treatment by a conventional method. In addition, as a makeup treatment layer, after performing a base treatment and, if necessary, a base treatment, a makeup such as a pattern or a pattern is formed, and a clear coating or the like is applied for the purpose of protecting the makeup and a laminate formation is performed. It was done.

At the time of transportation and storage, as shown in FIG. 8, a plurality of inorganic molded bodies are stacked and fixed by the fixing bands 26a and 26b such as a string or a band, so that the scratches or the like of the design constituent part and the groove part can be more reliably prevented. Damage can be prevented. Further, the same effect can be obtained by wrapping while applying relatively stronger tension to the joining / locking portion side with a plastic film or the like.

As described above, according to the inorganic molded article of the present invention, a convex portion is formed on one of the front surface and the rear surface so as to be located at the joining and locking portion, and a plurality of inorganic molded articles are formed on the other side. When stacked so that the front surface and the rear surface face each other, a concave portion that fits with the convex portion of the inorganic molded body facing each other is formed. By preventing misalignment and designing the position of the center of gravity rather than the joint locking portion, stacking is possible without contacting each design component, and damage to each design component can be prevented.
