2. Description of the Related Art Conventionally, as shown in FIG.
And the tip portion of the ridge portion a is made to protrude from the head side edge c of the valley portion b, and is formed to protrude obliquely outward on the insertion side located inside the ridge portion a during polymerization. The roof tile e having the embankment d is seen, and the roof tiles e are stacked in the same plane projection, and then tied.
The corner f near the valley b is pushed in contact with the ridge a of the roof tile below, so that the corner f is easily damaged, and the corner f is higher than the shape of the jetty d. Roof tiles e
However, as shown in FIG. 13, there is a disadvantage that the position is shifted to the left side and the height of the jetty d tends to be insufficient, so that the corner f is easily damaged. They had to be shifted and united.

[0003] However, if they are bound in this state, they cannot be placed on the pallet because the head and buttocks cannot be moved up and down. Has a drawback that the projected area on the plane is enlarged and the number of stacked sheets is remarkably reduced even in the same pallet.

[0004]

SUMMARY OF THE INVENTION The present invention prevents the protrusion of the roof tile body from being damaged at the time of binding by the interference prevention projection, and also prevents the tile from being misaligned to the beam side, and also impairs the appearance during roofing. Another object of the present invention is to provide a roof tile in which a projection for preventing interference that is not affected by distortion, shrinkage, and the like during firing is formed in a press molding step.

[0005]

SUMMARY OF THE INVENTION The present invention is based on the prior art and, in view of the problem such as breakage of a corner at a projecting portion of a ridge, prevents interference with the back surface of the apex of the outer peripheral surface of the projecting portion of the ridge. It is intended to provide a roof tile that has a projection and eliminates abutting of the leading edge of the pier portion at the time of stacking, prevents damage, and prevents misalignment to the pier side. is there.

The roof tile has a ridge portion bulging upward and a valley portion continuous with the ridge portion, and a tip portion of the ridge portion has a predetermined size from a head end edge of the valley portion. In the main body of the roof that has been protruded forward to form a protruding part, the outer peripheral surface of the protruding part is gradually
The slope is formed so as to increase the curvature , while the interference prevention projection is located at the inflection point between the valley behind the corner on the insertion side of the projection and the ridge, and the vertex of the outer peripheral surface is formed. It is formed so as to project downward so as to correspond to the circumferential portion on the back surface of the portion.

[0007]

According to the present invention, the projecting portion of the lower roof tile is formed by forming the outer peripheral surface portion of the projecting portion to be inclined and projecting the interference prevention projecting portion below the rear surface of the top of the outer peripheral portion. Since the upper roof tiles are stacked with the protrusions for preventing interference of the upper roof tiles protruding from the apexes on the outer peripheral surface of the lower roof tiles, A gap is provided between the ridge portion and the surface of the protruding portion, and the movement of the upper roof tile to the pier side is restricted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a roof tile which is a clay tile. An arc-shaped ridge portion 3 is formed, and a valley portion 5 which is formed substantially horizontally from the ridge portion 3 to the insertion side 4 on the other side is formed.

The ridge 3 has a protrusion 8 projecting forward by a predetermined distance from the end of the head portion 7 of the valley 5 in the tile body 6, and the width of the protrusion 8 is shifted to the tip. The four side surfaces on the insertion side of the protruding portion 8 are formed as inclined surfaces so that the width becomes narrower according to the following.

The outer peripheral surface 8a of the projection 8 has a generally triangular cut section in a longitudinal sectional view. More specifically, the outer peripheral surface 8a of the projection 8 gradually changes in curvature as it moves from the rear to the front end of the projection 8. It is inclined downward to become large ,
The thickness from the rear portion to the tip portion is gradually reduced.

A vertex portion A of the outer peripheral surface portion 8a, which is a rear portion, is formed.
In the present embodiment, the position of the
In the lateral direction of the head hanging 7 on the head side 7 and the roof tile body 6.

The edge of the ridge portion 3 on the side of the pier 2 is substantially straight.

The bulging radius of the ridge portion 3 may be substantially the same as going from the head side 7 to the butt side 9 or may be gradually decreasing in diameter. When the head side 7 is superimposed on the butt side 9 with a predetermined overlapping margin, the inner diameter of the tip portion of the head side 7 (projection 8) of the ridge portion 3 is changed to the cross The outer diameter of the ridge 3 is slightly larger than or substantially equal to the outer diameter.

In addition, a head hanging of a predetermined hanging dimension X1 is provided at an edge of the head side 7 on the back surface 10 of the valley 5 and the ridge 3 (projecting part 8).
11 are provided continuously, and the inner diameter refers to the lower edge of the head hanging 11.

Numeral 12 denotes an interference preventing projection. The interference preventing projection 12 is a corner 13 on the insertion side 4 of the projecting portion 8 of the ridge 3.
The position corresponding to the inflection point portion between the rear valley portion 5 and the ridge portion 3 and the circumferential position on the back surface 10 of the apex portion A of the outer peripheral surface portion 8a. It is substantially the same as the hanging dimension X1 and is formed to project downward.

The interference preventing projection 12 may be formed continuously with the head hanging 11 as shown by a broken line B in FIG.

In the figure, reference numeral 14 designates 2 provided on the butt side 9 of the pier section 3.
A stepped cut, 15 is a water return provided continuously on the edge 9 on the tail side of the surface 16 of the tile body 6, and 17 is a dike provided on the side edge of the insertion side 4 and protruding diagonally outward. The valley 5 in front of the jetty 17 has a step 18 having a predetermined step.

In the figure, reference numeral 19 denotes a hook provided at the edge of the bottom side 9 of the heavy surface 10 of the tile body 6, and reference numeral 20 denotes a jetty 17 for eliminating inclination in the width direction when the roof tiles 1 are stacked. The pedestal provided on the back, 21 is the edge of the head side 7 on the back 10 of the tile body 6 (the valley 5 side)
These are ridges formed in parallel with a predetermined interval from the head droop 11.

Next, the operation of the roof tile according to the present invention will be described. ), A predetermined number of sheets are stacked, and then tied using a tying material such as a PP band.

That is, the outer peripheral surface 8a of the projecting portion 8 is formed to be inclined, and the interference preventing projection 12 is formed so as to project below the vertex A back surface 10 of the outer peripheral surface 8a. Since the protrusions 8 are stacked with the interference prevention protrusions 12 of the upper roof tile 1 abutting on the vertices A of the outer peripheral surface portion 8a of the protrusion 8, the insertion of the protrusion 8 in the ridge portion 3 of the upper roof tile 1 is performed. A gap can be provided between the lower end portion of the corner 13 of the side 4 and the outer peripheral surface 8a of the protruding portion 8 of the ridge portion 3 of the lower roof tile 1.

When the upper roof tile 1 is moved to the crosspiece side 2, since the interference prevention projection 12 is in contact with the curved portion of the insertion side 4 of the crosspiece 3, the roof tile 1 is not moved. The positional deviation to the left side (crossing side 2) when stacking is restricted.

[0022]

According to the present invention, the present invention has a ridge 3 which bulges upward and a valley 5 which is continuous with the ridge 3. The tip of the ridge 3 is located on the head side of the valley 5. In the tile main body 6 formed by projecting forward from the end edge by a predetermined distance to form the projecting portion 8, the curvature of the outer peripheral surface portion 8 a of the projecting portion 8 gradually increases as the position moves from the rear portion of the projecting portion 8 to the front end portion. The interference prevention projection 12 is positioned at the inflection point between the valley 5 and the ridge 3 behind the corner 13 on the insertion side 4 of the projection 8, and the outer peripheral surface 8a is formed. Is formed so as to correspond to the circumferential portion of the back surface 10 of the vertex A of the upper roof tile 1, so that the lower end portion of the insertion side quadrangular portion 13 of the projecting portion 8 in the ridge portion 3 of the upper roof tile 1 and the lower roof tile The first ridge 3 is stacked with a gap between the ridge 3 and the outer peripheral surface 8a of the protrusion 8. In addition, the concentration of stress applied to the corners 13 of the protruding portion 8 at the time of binding can be eliminated, and the protruding portion 8 can be reliably prevented from being damaged. Since the roof tiles 1 are in contact with the curved portions, it is possible to prevent displacement of the roof tiles 1 on the left side (the side of the crossbar 2) when the roof tiles 1 are stacked. , So that the appearance at the time of roofing is not impaired at all, and it is only necessary to protrude from the periphery of the lower end of the head side 7 of the back surface 10 of the ridge portion 3. The practical effect is extremely large, for example, the interference prevention projection 12 which is not affected can be surely formed in the press molding stage.
