Description

TECHNICAL FIELD The present invention relates to a flat roof tile.

(Prior Art) Conventional flat tiles are known, for example, as described in Japanese Utility Model Laid-Open No. 62-7525.

This conventional flat roof tile is provided on both left and right sides of the main body portion with an engaging portion that serves as a connecting portion with a horizontally adjacent flat roof tile in a roofing state, and the main body portion has a flat surface. A plurality of recesses extending in the front-rear direction were formed on the back surface.

(Problems to be solved by the invention) However, in such a conventional flat tile, the surface of the main body portion is formed flat, and when a plurality of flat tiles are stacked, There was nothing to regulate the deviation movement, so it was a poor stacking property.

Therefore, for example, as shown in FIG. 8, when temporarily stacking the flat tiles when the roof is being roofed, or as shown in FIG. 9, the flat tiles are collectively transported by a transport machine. In some cases, the stacked flat tiles may be displaced from each other and fall from the roof or transport aircraft.

It is an object of the present invention to solve the above-mentioned problems and to prevent the horizontal tiles from shifting in the left-right direction and the front-back direction during stacking, and to provide a flat tile having good stackability.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the flat tile of the present invention has a nail hole having a pedestal at a rear edge portion which is a overlapping portion with a flat tile adjacent to the ridge in a roofing state. A recess having a shape that can be fitted to the pedestal is formed on the back side of the pedestal.
At least the front and rear and the left and right are provided with movement restricting surfaces.

(Operation) When a plurality of flat roof tiles of the present invention are vertically stacked, the recesses and the bases of the vertically adjacent flat roof tiles are fitted to each other.

In this way, the stacked flat tiles prevent the lateral displacement and the longitudinal displacement by the pedestal being sandwiched between the front and rear and the left and right by the movement restricting surface of the recess. Will be.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

First, the structure of the first embodiment shown in FIGS. 1 to 5 will be described.

As shown in FIGS. 1 and 2, the flat roof tile 1 of the present embodiment is a flat roof tile having a flat main body portion. Corrugated engaging portions 11 and 12 that serve as connecting portions with 1 are provided.

In addition, on the surface of the trailing edge part that overlaps with the flat tile 1 adjacent to the ridge side in the roofing state, there are nail holes 14 having circular pedestals 13 at two places on the left and right that divide the width of the flat tile into three equal parts. Has been formed.

A waterproof wall 15 is provided upright on the back surface of the flat tile 1 so as to surround all of the rear edge, the front edge, the left side edge, and the right side edge.
Ribs 16 are erected upright and extending in the front-rear direction at two places on the left and right, which divide the width of each of the parts into three equal parts. The front end of the rib 16 is provided at a position spaced apart from the waterproof wall 15 at the front edge rearward by a predetermined width, and the rear end is provided continuously to the waterproof wall 15 at the rear edge. Further, the rib 16 is formed in a cylindrical shape having an inner diameter larger than the outer diameter of the pedestal 13 at a portion located on the back side of the nail hole 14, and is linearly formed at both front and rear portions thereof. That is, the cylindrical portion 161 of the rib 16 forms a circular recess 17 that can be fitted into the pedestal 13, and the inner peripheral surface 171 of the recess 17 serves as a movement restricting surface.

 Next, the operation of the first embodiment will be described.

As shown in FIG. 3 and FIG. 4, when a plurality of flat roof tiles 1 of this embodiment are vertically stacked, the flat roof tiles 1, 1 vertically adjacent to each other have the recess 17 of the upper flat roof tile 1 on the lower side. It is fitted to the pedestal 13 of the flat tile 1.

Therefore, the stacked flat tiles 1, 1 are prevented from shifting in the left-right direction and the front-back direction by the pedestal 13 being sandwiched by the inner peripheral surface 171 of the recess 17 from the entire circumferential direction including the front-back and left-right directions. Will be.

As described above, the flat tile 1 of this embodiment has a good stacking property. Therefore, for example, as shown in FIG. 8, when the flat tiles 1 stacked when the roof is roofed are temporarily placed on the roof 4, , 9th
As shown in the figure, when the flat roof tiles 1 are collectively transported by the transportation machine 5, there is no concern that the flat roof tiles 1 are displaced and fall from the roof 4 or the transportation machine 5, which is convenient.

Further, as shown in FIG. 5, when the flat tiles 1 are to be laid, each flat tile 1 is fixed by hammering the nail 2 into the small dance (not shown) from the nail hole 14 and fixing it in FIG. As shown, with the front edge of the flat tile 1 adjacent to the ridge on the rear edge, the roof is sequentially moved from the eaves to the ridge. In addition, the overlapping width of the flat tile 1 is set in the wide groove 18 formed between the waterproof wall 15 at the front edge and the rib 16 at the side adjacent to the ridge.
It can be adjusted within the range in which the pedestal 13 is arranged.

Further, since the pedestal 13 is provided, it is difficult for rainwater flowing on the surface of the flat tile 1 to enter the nail holes 14. That is, it is possible to prevent corrosion of the small dance and the base plate 3.

Next, a second embodiment shown in FIGS. 6 and 7 will be described.

In the description of the second embodiment, the same components as those in the first embodiment will be denoted by the same reference numerals with "a" added, and the description thereof will be omitted. Regarding the operation, the description of the same operation as that of the first embodiment is omitted.

The flat tile 1a of the present embodiment has an oval pedestal 13a on the surface of the trailing edge.
A nail hole 14a having a vertical rib 19 extending in the front-rear direction and a horizontal rib 20 extending in the left-right direction is formed on the back surface.
And are erected. Further, the vertical ribs 19 and the horizontal ribs 20 are cut out at the portions intersecting with each other, and the recessed portions 21 having a shape capable of fitting with the pedestal 13a are formed at the cutout portions. The vertical ribs 19 and the horizontal ribs 20 are positioned so that the recesses 21 are located on the back side of the pedestal 13a.

Therefore, the notched surfaces 191 and 192 of the vertical ribs 19 serve as movement restricting surfaces that prevent the vertical tiles 1a and 1a from being vertically displaced from each other, and the notched surfaces 201 and 202 of the horizontal ribs 20 are vertically stacked. The flat roof tiles 1a, 1a serve as a movement restricting surface for preventing a displacement movement in the left-right direction.

The embodiment of the present invention has been described in detail above with reference to the drawings.
The specific configuration is not limited to this embodiment, and the present invention includes a design change and the like within a range not departing from the gist of the present invention.

For example, in the embodiment, the pedestal and the recess are partially formed, but they may be formed continuously over substantially the entire length in the left-right direction.

Further, in the embodiment, among the displacement movement preventing means composed of the pedestal and the concave portion, the pedestal uses the pedestal of the nail hole, but the pedestal as the displacement movement preventing means may be provided independently. Further, in that case, the base of the nail hole may not be provided.

Further, although the nail hole is the bottomed hole in the embodiment, it may be a through hole penetrating the back surface of the flat roof tile.

(Effects of the Invention) As described above, in the flat tile of the present invention,
Since the nail hole with the pedestal is formed, it is difficult for rainwater flowing on the surface of the flat tile to enter the nail hole, and when the flat tiles are vertically stacked, the flat tiles are left and right side by side. It is possible to obtain the effect that the stacking property is good without any displacement in the front-back direction.
