Description

  The present invention relates to a tile installed on the upper surface of a roof base plate.

  Conventionally, the top and bottom surfaces of the tiles are placed on top of the base plate that is made of timber and is the base material of the roof. The roof tiles were laid out in order in order by hooking a locking projection provided to project to a predetermined dimension. In order to prevent most of the raised tiles from being moved or blown away by large winds such as typhoons or vibrations such as earthquakes, nails are placed in nail holes provided in the tiles beforehand. To fix the roof tiles. In this way, the fired tile was prevented from being moved or blown away by wind or vibration.

  However, when fixing a roof tile by placing a nail in a nail hole provided in the roof tile, the user had to drive the nail with a nail in one hand and a hammer in the other hand. For this reason, the construction work of the roof tile was very complicated. In order to eliminate such complicated construction work of tile roofing, a lightweight metal material with corrosion resistance, a reference piece formed slightly higher than the height of the tile, and a lower end portion of this reference piece in the horizontal direction A position restricting member formed integrally with a fixing piece formed at a right angle to the upper end of the reference piece, a locking piece bent to the left and a locking piece bent to the right of the locking piece. It was configured to be attached to the tile rail and to prevent the tile from being lifted by a large wind or the like by pressing the upper surface of the tile insertion side with a locking piece provided on the position regulating member (see Patent Document 1).

In this case, since the position restricting members were attached to the roof tiles corresponding to the respective roof tiles, it is possible to prevent the roof tiles from being lifted by a large wind, etc. turn into. Therefore, a method that can eliminate the complexity of the work of attaching the roof tile and the position regulating member is also conceivable. In this case, an elastic tile locking bar extending substantially parallel to the roof eave is formed in a substantially U-shaped cross section, and the tile locking bar protrudes downward from one side of the tile. A holding portion with which the protrusion is engaged is provided, and the holding protrusion of the roof tile is held on the holding portion, and the upper surface of the roof tile is engaged with a locking piece provided on the roof tile locking bar. As a result, a plurality of tiles can be simultaneously held on the tile locking bars extended substantially parallel to the eaves of the roof, so that it is possible to eliminate the complicated work of attaching the tiles and the position regulating members. become able to.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a roof tile 23 showing an embodiment of the present invention, and FIG. 2 is an enlarged side view of a main part of the roof tile 23 of FIG.

  The tiles 23 have a plurality of shapes such as corrugated tiles (corrugated tiles such as J-shaped tiles and F-shaped double tiles) or flat tiles (substantially flat tiles such as F-shaped tiles and F-shaped disaster prevention tiles). The J-shaped roof tile (hereinafter referred to as a roof tile 23) has a main body 24 formed in a substantially rectangular shape on the upper surface as shown in FIG. It has a curved shape curved downward. At the upper end 24C (lower side in FIG. 1) of the main body 24, two locking projections 25 having a predetermined thickness are provided at predetermined intervals. Projecting to a predetermined dimension. A superposed portion 26 having a predetermined width extending from the lower end 24D (upper side in the figure) to the upper end 24C is provided on one side 24A (right side in the figure) of the main body 24.

  A locking groove 28 having a predetermined width is formed in a substantially straight line on the surface of the upper end 24 </ b> C that is one side end surface of the main body 24, and the locking groove 28 is formed with a predetermined size recess in the direction of the lower end 24 </ b> D of the main body 24 ( 2 and extends from one side 24A of the upper surface 24C in the direction of the other side 24B (in the horizontal direction in the figure). One side in the width direction of the locking groove 28 (in the direction of the lower surface 23B of the roof tile 23) is formed in contact with the upper surface 23A of the roof tile 23 at the substantially central portion of the cross section of the main body 24, and the other side in the width direction is substantially cross section. It is formed at a predetermined distance from the upper surface 23A of the central portion.

  The locking groove 28 is formed in a substantially straight line on the upper end 24C surface of the roof tile 23 in which the main body 24 is formed in a curved shape, and this locking groove 28 is an upper surface 23A of the roof tile 23 between the locking projections 25, 25. While opening the side, the both sides penetrate the main body 24, penetrate the lower surface 23B side of the roof tile 23 and open there. Further, the roof tile 23 is provided with a nail hole 27 (shown in FIG. 1) for driving and fixing a nail to a conventional roof tile locking bar (not shown) made of wood. That is, the locking groove 28 is provided on the upper end 24C surface which is one end surface of the main body 24, and the locking groove 28 is configured to be insertable into a locking piece 14 formed on the tile locking bar 10 described later. .

  The tile locking bar 10 is fixed to the upper surface of the field plate 21 of the roof 20 (shown in FIG. 7), engages the locking protrusion 25 of the tile 23 and locks the locking groove 28. It is provided substantially parallel to the eaves 20A of the roof 20, and extends from one end of the eave 20A to the other end. 3 and 4, the tile locking bar 10 is inserted into the holding portion 12 where the locking protrusion 25 of the roof tile 23 is engaged with the bottom portion 13 and the locking groove 28 of the roof tile 23. The engaging piece 14 is constituted.

  The tile locking bar 10 is formed of a metal plate material having elasticity that does not easily rust, such as a stainless steel plate or a linseed copper plate, and the holding portion 12 and the locking piece 14 are formed of a bent metal plate material. It is configured integrally. The holding portion 12 includes a bottom piece 12B fixed to the base plate 21, a rear piece 12C that is erected by bending one side of the bottom piece 12B, and a front piece 12A that is erected by bending the other side of the bottom piece 12B. Are formed in a substantially U-shaped cross section. Although not shown, the bottom piece 12B is provided with a nail hole for fixing the bottom piece 12B to the base plate 21.

  The space between the front piece 12A and the rear piece 12C is formed at an interval substantially equal to the thickness of the locking projection 25 of the roof tile 23, and the gap between the front piece 12A and the rear piece 12C is formed by this gap. The 23 locking projections 25 can be engaged with each other without backlash. The front piece 12 </ b> A has a short dimension that does not come into contact with the lower surface 23 </ b> B of the roof tile 23 in a state in which the locking projection 25 is held by the holding unit 12.

  The rear piece 12C extends to a locking groove 28 provided in the main body 24 in a state where the holding protrusion 12 holds the locking protrusion 25 of the roof tile 23, and the upper end of the rear piece 12C is connected to the engagement piece 28C. A stop piece 14 is provided. The upper end of the rear piece 12C is bent at a substantially right angle and extends to the front piece 12A side with a predetermined dimension, and the locking piece 14 extends substantially parallel to the bottom piece 12B. The length of the locking piece 14 is substantially the same as the depth of the locking groove 28. Specifically, the length dimension of the locking piece 14 is substantially the same as the depth of the locking groove 28 or is slightly shorter.

  Then, the tile locking bar 10 configured in this manner is used as a base plate 21 as a base material of the roof 20 as shown in FIG. 5 (in this case, a waterproof sheet is provided on the upper surface of the base plate 21 although not shown). ) Arranged on the upper surface and the tile locking bar 10 is arranged substantially parallel to the eaves 20A. The tile locking bar 10 is laid at a predetermined interval with respect to the tile 23 to be lifted in the rain flow direction of the roof 20.

  In this case, the tile locking bar 10 is laid with the front piece 12A of the holding portion 12 positioned on the eave 20A side and the rear piece 12C positioned on the opposite side of the eave 20A. Then, a nail 35 (shown in FIG. 6) is driven into a nail hole (not shown) provided in the bottom piece 12B of the holding portion 12. Thereby, as shown in FIG. 7, the roof tiles 10 are fixed to the upper surface of the base plate 21 at a predetermined interval. At this time, since the tile locking bar 10 is configured so that the size of the locking piece 14 is smaller than the size of the bottom piece 12B, when the nail 35 is driven into the nail hole, the locking piece 14 hardly interferes with the bottom piece. The nail 35 can be driven into the 12B nail hole.

  Then, after fixing the tile locking bar 10 to the upper surface of the field plate 21 by hitting the nails 35 at predetermined intervals, the roof 23 is engaged with the tile locking bar 10. In this case, the locking projection 25 protruding from the lower surface 23B on the upper end 24C side of the roof tile 23 is engaged with the holding section 12 provided on the bottom 13 of the roof tile locking bar 10. The locking piece 14 is pushed in the separating direction of the front piece 12A on the upper end 24C surface. As a result, the locking piece 14 is elastically deformed in the direction of the separation side of the front piece 12A as shown by the arrow in FIG. At this time, the rear piece 12C is elastically deformed while being careful not to elastically deform the gap between the rear piece 12A and the front piece 12A more than the dimension capable of inserting the locking projection 25. In this case, since the tile locking bar 10 is made of a metal plate having elasticity, the locking piece 14 can be easily elastically deformed.

  Then, when the gap between the upper end of the front piece 12A and the rear piece 12C is opened to a width where the locking protrusion 25 can be inserted, the locking protrusion 25 is inserted into the gap between the front piece 12A and the rear piece 12C. As a result, the locking projection 25 of the roof tile 23 is held by the holding section 12 of the roof tile locking bar 10, and the locking piece 14 is positioned in the locking groove 28 of the main body 24. When the locking piece 14 is positioned in the locking groove 28 of the main body 24, the locking piece 14 is elastically returned in the direction of the front piece 12A as shown in FIG. When the locking piece 14 is elastically restored, the locking piece 14 is inserted into the locking groove 28 provided in the upper end 24C of the roof tile 23 and locked. That is, the locking projection 25 of the roof tile 23 is held by the holding section 12 of the roof tile locking bar 10 and is locked by the locking piece 28 in the locking groove 28, so that the roof tile 23 is subjected to external forces such as vibration and wind.
