[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a cement mortar. The present invention relates to an eaves side of a tile body placed on a ridge side near a ridge end on the front side surface of a tile body placed on an eave side. The present invention relates to a roof tile that is laid in a state where the rear side surfaces of the ends are opposed to each other.

[0002]

2. Description of the Related Art Generally, when a roof tile is laid on a roof base plate, an end portion of a tile body laid on an eave side (hereinafter, simply referred to as an "eave side tile body"). The roof tile body on the ridge side (hereinafter simply referred to as the “ridge roof tile body”)
Laying from the eaves side of the roof to the ridge side, overlapping the eaves side end of the roof. At this time, the shapes of the surfaces that come into contact with each other,
It is rare that the surface shape of the ridge side end of the front side surface of the eaves tile main body and the surface shape of the eaves side end of the back side surface of the ridge side tile main body completely abut. For this reason, when the tile bodies are placed one on top of the other, the two tile bodies are often in partial contact with each other.

[0003]

The above-mentioned conventional roof tiles have the following problems. In other words, when the eaves-side tile body and the ridge-side tile body are in partial contact with each other, when an operator is placed on the tile body at the time of laying the tile body, or when the upper floor is For example, when snow falls from the roof, an impact force is locally applied to the contact portion between the eaves-side tile body and the ridge-side tile body, and these tile bodies may be damaged. In addition, when the worker slips on the already laid tile body and the position of the tile body shifts, there is a danger that the worker may lose balance and the like.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks of the prior art, to have good crack resistance against an external force applied in a state of being laid on a roof, and to position tile bodies laid vertically on each other. An object of the present invention is to provide a roof tile that is difficult to be shifted.

[Means for Solving the Problems]

(Structure 1) The roof tile according to the present invention is characterized in that a concentrated load distribution member is integrally provided on the back side surface of the eave-side end as described in claim 1. (Operation / Effect) If the load distribution mechanism is provided on the back surface of the tile main body as in the present configuration, the tile main bodies stacked one on the other will not locally contact each other. Therefore, even when an external force such as a worker's weight or snow load acts on the surface of the laid tile body, the external force is dispersed and transmitted to the lower tile body, so that the tile body is damaged. The opportunity to do so is greatly reduced.

(Structure 2) In the roof tile according to the present invention, the concentrated load dispersing member can be formed of a rubber material. (Operation / Effect) In general, since rubber material has excellent elastic deformability, when the roof tile on the ridge side is laid on the front side of the roof tile on the eave side, the rubber is used as the roof tile on the eave side. Make sure it adheres to the front side of As a result, the force acting between the two roof tiles is dispersed, and the chance of the roof tiles being damaged can be reduced. In addition, since the rubber material is excellent in durability, the above effect can be maintained for a long time.

(Structure 3) In the roof tile according to the present invention, the concentrated load dispersing member can be formed of a fiber material. (Function / Effect) Even when a fiber material is used as in the present configuration, the front side of the roof tile on the eave side and the back side of the roof tile on the ridge side can be securely brought into close contact with each other. The force acting between the roof tiles can be dispersed.

(Structure 4) In the roof tile according to the present invention, as described in claim 4, the concentrated load dispersing member can be formed of a moisture-curable resin material. (Operation / Effect) In the case of this configuration, the operation
Similarly to the effect, the front side surface of the roof tile on the eaves side and the back side surface of the roof tile on the ridge side can be securely adhered, and the force acting between both roof tiles can be dispersed. .

(Structure 5) In the roof tile according to the present invention, as described in claim 5, the concentrated load dispersing member can be dispersedly provided at a plurality of locations on the back side surface of the eaves side end. (Function / Effect) In the range where the roof tile has a predetermined crack resistance, it is better to partially provide the concentrated load dispersing member as in the present configuration, because the rubber material, the fiber material, or the moisture-curable resin material is used. The amount used can be reduced, which is economically advantageous.

BEST MODE FOR CARRYING OUT THE INVENTION (Tile Body) The roof tile of the present invention is mainly intended for a so-called thick tile having a predetermined thickness. In the present embodiment, the thick tile is, for example, shown in FIGS. In this case, the case of the flat tile body 1 will be described. The tile body 1 has a substantially rectangular shape, and has two side ends 2 along the gradient direction X of the roof, which are adjacent to a roof in a direction Y parallel to the eaves (hereinafter referred to as a “lateral direction Y”). A jointed portion 3 for overlapping one another is formed. On the other hand, at the ridge side end 4 of the two ends of the tile main body 1 along the left-right direction Y, a hooking ridge S is formed so as to protrude toward the back side surface 6 of the tile main body 1. The hanging ridge S is for fixing the tile main body 1 by hooking the tile main body 1 on the roof ridge 7 provided on the roof surface. And in the vicinity of the eaves side end 8,
A concentrated load dispersing member 9 is attached to the back side surface 5 of the tile body 1. The concentrated load dispersing member 9 is a ridge-side tile main body 1M laid.
And the eaves-side tile body 1N is interposed at the contact portion. Due to the concentrated load dispersing member 9, the load applied to the ridge side tile body 1M placed on the upper side, for example, the weight of the worker or the snow load when laying the ridge side tile body 1M is reduced by the lower eave side tile. The roof tiles 1M and 1N are distributed and transmitted to the main body 1N.
Is effectively prevented from being damaged.

The concentrated load dispersing member 9 is made of, for example, a rubber material, a fiber material, or a moisture-curable resin material. The concentrated load dispersing member 9 may be provided over the entire width along the left-right direction Y on the back side surface 5 near the eaves-side end portion 8 or may be distributed along the same direction as shown in FIG. You may. In order to disperse the load applied to the ridge-side tile body 1M, the area of the concentrated load dispersing member 9 is preferably as large as possible. Is more economically advantageous. Although the thickness of the concentrated load dispersing member 9 can be set arbitrarily, it is preferable that the thickness is such that the tile bodies 1 do not contact each other even in a state where at least the rubber material or the fiber material constituting the concentrated load dispersing member 9 is deformed. Therefore, the thickness of the concentrated load dispersing member 9 is desirably, for example, about several mm to 5 mm.

(Laying of the Tile Body) The roof tile of the present invention is shown in FIG.
As shown in (1), while hanging the hooks S of the tile body 1 on the roof 7 attached to the ground board 10, the tile bodies 1 are first arranged side by side in the left-right direction Y along the eaves. Adjacent tile body 1
The side ends 2 are placed on top of each other. After the completion of the laying in the left-right direction Y, the ridge side tile main body 1M in the ridge side row is laid subsequently. At this time, the eave-side end 8 of the ridge-side tile body 1M overlaps with the front side surface 6 of the eave-side tile body 1N and near the ridge-side end 4,
The concentrated load dispersing member 9 provided on the lower surface of the eaves-side end 8 intervenes in the gap between both the tile bodies 1M and 1N.

Further, the concentrated load dispersing member 9 functions effectively during transportation before laying or during temporary placement.
That is, the concentrated load dispersing member 9 concentrates the upper tile body 1 on the front side surface 6 near the eaves end 8 of the lower tile body 1 among the vertically stacked tile bodies 1 stacked vertically. The load distribution member 9 contacts. Therefore, it is possible to prevent the front side surface 6 of the tile body 1 from being scratched. Further, the thickness of the concentrated load dispersing member 9 is set to a predetermined value so that when the tile bodies 1 are stacked, the front side surface 6 of each tile body 1 is substantially horizontal. This makes it possible to stack a plurality of the tile bodies 1 in the vertical direction with respect to the ground, and obtain a stable temporary placement state. As described above, the concentrated load dispersing member 9 not only prevents the tile body 1 from being damaged, but also the vicinity of the eaves side end 8 of the front side surface 6 of the tile body 1 stacked below, that is, laying. No flaws are formed on the parts constituting the later appearance. Therefore, it is not necessary to repair flaws, and there is no inconvenience that the commercial value of the roof tile is reduced.

(Manufacturing Method) FIG. 4 shows a manufacturing process of the tile body 1 according to the present invention. On the production line, a plurality of lower dies 11 forming the shape of the back side surface 5 of the tile main body 1 are sequentially conveyed by a belt conveyor B or the like. Cement mortar C1 is continuously placed from mortar hopper H1. The lower mold 11 forms the shape of the rear side surface 5 of the tile body 1, and one lower mold 11 is prepared to manufacture one tile body 1. Thereafter, the lower mold 11 and the cement mortar C1 pass below a substantially cylindrical upper mold 13 rotating around a horizontal axis.
The shape of the front side surface 6 is formed. Before placing the cement mortar C1 on the upper surface 12 of the lower mold 11, the concentrated load dispersing member 9 may be made of a rubber material, a fiber material,
A moisture-curable resin material is provided on the upper surface 12. For example, a mixing member G in which a synthetic resin or the like is mixed with rubber powder as a binder is transferred from the mixing member hopper H2 to a corresponding portion of the lower mold 11 in accordance with a timing at which the lower mold 11 is conveyed to a predetermined position. Supply. As the rubber powder, for example, powdered waste tires can be used. The particle size of the rubber powder may be set arbitrarily.
As the binder, for example, an emulsion-type adhesive using acrylic or the like, an epoxy resin, or a hot-melt adhesive using urethane or the like can be used.
Note that a rubber member formed in advance can be used instead of the mixing member G using the rubber powder. For example, similarly to the above, a laminated material or the like using waste tire powder may be arranged on the upper surface of the lower mold 11 and buried in the cement mortar C1 placed later. In addition, for example, a fluid rubber can be used. In this case, the fluid rubber is supplied to a corresponding portion of the lower mold 11, and then the cement mortar C1 is placed.

On the other hand, when the concentrated load dispersing member 9 is formed of a fiber material, for example, short fibers formed in a needle shape are supplied to the upper surface 12 of the lower mold 11 together with various binders, or A nonwoven fabric or the like is placed on the lower mold 11 and then the cement mortar C1 can be placed. As the binder, the same one as in the case of the rubber member can be used. When the concentrated load dispersing member 9 is made of a moisture-curable resin, for example, a moisture-curable hot melt that is used for siding or the like to be attached as a finishing plate to an outer wall of a building can be used. In this case, the moisture-curable hot melt is supplied to the upper surface 12 of the lower mold 11 in a fluidized state, and the cement mortar C1 is placed thereon. It reacts with the moisture in the cement mortar and hardens.

The cement mortar C1 continuously placed on the upper surface 12 of the lower mold 11 is then separated individually using a cutter 14, and the front side surface 6 is pre-painted, and then the lower surface 11 Dry curing is carried out while being placed on the side mold 11. In a so-called post-process after the completion of the drying curing, the roof tile body 1 is separated from the lower mold 11, subjected to post-coating, and then dried again to complete a roof tile.

In the above-described example, the method of mounting the cement mortar C1 after mounting a rubber member or the like on the upper surface 12 of the lower mold 11 to mount the concentrated load dispersing member 9 is used. However, the present invention is not limited to this method, and a rubber member or the like may be attached in the post-process of the tile body 1. For example, between the so-called stripping die separation step of separating the tile body 1 from the lower die 11 and a post-coating step of performing a top coating, or between a post-coating step and a drying step, Etc. may be attached. When a rubber member or a moisture-curable resin material is attached, the tackiness or adhesiveness of these materials themselves can be used, or they can be separately attached using an adhesive. On the other hand, the fiber material can be attached using various adhesives. The rubber member itself, or an adhesive or the like for attaching the rubber member, the fiber material, or the like is dried in a subsequent drying step. The attachment of the rubber member or the like may be performed after the drying step. In this case, when the rubber member or the like is adhered to the tile main body 1 using an adhesive, it is convenient to use an adhesive of a quick-drying type or a moisture-curing type that does not need to be dried. However, in a subsequent step, the concentrated load dispersing member 9 is used.
In order to attach the concentrated load dispersing member 9, usually, the rear side surface 5 of the tile body 1 faces downward, so that a device for inverting the tile body 1 or a rubber member or the like from below is used. It may be necessary to provide a hopper that can supply.

Since the roof tile according to the present invention has an excellent load distribution function, there is no possibility of breakage even during laying work or snow accumulation, and the roof tile body 1 is stacked upon transportation or temporary placement. The front side 6 of the tile body 1 when placed
Scratches are unlikely to occur. As described above, according to the present invention, it was possible to obtain a roof tile that has little chance of needing repair and has little loss of commercial value.

[Other Embodiments] <1> In the above embodiment, an example was shown in which the roof tiles were formed in a flat plate shape. However, as shown in FIG. 5, the tile body 1 may have a corrugated shape. . In this case, the concentrated load dispersing member 9 may be provided partially on the eaves-side end 8 of the tile body 1A, or may be provided over the entire length of the eaves-side end 8 although not shown. .

<2> In the above embodiment, the concentrated load distribution member 9 is provided only in the vicinity of the eaves-side end 8. However, for example, it may be provided over the entire back side surface 5 of the tile body 1. . With this configuration, it is possible to expect a soundproofing effect by absorbing the micro vibration of the roof tile body 1 at the time of rainfall or the like.

In the description of the appended claims, reference is made to the drawings and, in order to facilitate comparison with the drawings, reference numerals are used. However, it is not intended that the invention be limited to the configuration shown in the accompanying drawings. Absent.
