Description

The present invention relates to a long tile that forms a tile roof ridge.

Traditionally, clay-style Japanese tiles have been preferred for the roofs of traditional Japanese wooden houses. In particular, tiled roofs in which roof tiles covered with pier tiles are stacked on top of each other, and roof tiles are placed on top of each other, and tile roofs are placed on both sides have a personality, weather resistance and thermal insulation. Has also been favored by Japanese-style wooden houses. However, clay-style Japanese tiles are heavy, so the center of gravity of the house is high, and in the event of a large earthquake, the possibility of collapse increases, and when the tiles fall due to earthquake motion, the impact is large, When damaged, the edges are sharp, which can cause severe damage when hit. People have been devised in various ways such as building design strength and roof tile construction methods. With regard to the roof tile and its construction method, for example, a resin roof tile formed by molding a resin to reduce the weight has been proposed (see Patent Document 1 and Patent Document 2). In addition, a roof structure (see Patent Document 3) that improves the workability and strength by using a long roof tile that is formed in a series in the vertical direction from the ridge to the eaves and a ridge roof tile that is integrally molded. A roof tile (refer to Patent Document 4) is also proposed in which the surface door tile, the roof tile, and the crown tile to be formed are integrally molded with a resin to reduce the weight and facilitate the construction.

However, in the recent Great East Japan Earthquake, there were many collapses of tile roofs, especially the ridge tiles that form the ridges, despite having little impact on the building itself. This is because a large force was applied to the tall and heavy ridge tiles due to long-period vibration, and a large number of glazed roof tiles with a width of 250 mm to 260 mm were arranged at the same time. It is probable that the strength unbalance tends to occur at the joint of the roof tiles, and when a large force is repeatedly applied, the ridge part partially collapses, which has spread one after another.
Therefore, simply restoring the collapsed ridge tiles may cause them to collapse again due to an earthquake, while it is expensive to renovate the entire roof using metal tiles or lightweight roofing materials. Moreover, the method of partial renovation using the roof tile proposed in Patent Document 3 and Patent Document 4 is different from the heavy roof using Japanese-style tiles, the atmosphere is different, and the entire roof is harmonized. Have difficulty.
In view of the above circumstances, the present invention eliminates the structural weakness of a roof tile against earthquakes while taking advantage of the atmosphere and characteristics of a tile roof in a traditional Japanese house, and is a roof tile that is easy to construct when repairing or newly installing a roof tile. The purpose is to provide.

The long tile for a building of the present invention is a long tile for a building that forms a roof of a tile roof, the main component is resin, and the longitudinal dimension is more than twice the width of the tile, and has a cross section in the short direction. It has a long roof tile with a flat center and bent at both ends, and a long crown roof with a semicircular or chevron cross section in the short direction.
Thus, if the ridge tile is formed of resin, the weight is reduced, and the force acting on the ridge tile is reduced even if long-period vibration occurs during an earthquake. In addition, since the roof tiles are longer than ordinary roof tiles, the number of joints of the roof tiles is reduced, which eliminates the structural weakness of the entire roof tiles, and at the same time shortens the construction time and labor.
In addition, the long roof tile and the long crown tile can be provided with a plurality of reinforcing ribs in the longitudinal direction and the short direction of the back surface, respectively, so that the weight can be further reduced and the strength can be increased.

Here, the long long roof tile has a first long roof tile and a second long roof tile with different widths in the short direction, and the width of the second long roof tile is the first long The width of the first long roof tile is narrower than that of the first long roof tile, and the first long roof tile has a pair of water-stopping ribs in the longitudinal direction of the surface. It is preferable that the width of the pair of water-stopping ribs of the first long glazed roof tile is engaged with both side ends of the second long glazed roof tile. It is preferable to combine them.
In this way, if the roof tile is composed of two types of long tile roof tiles, there will be no sense of incongruity with a heavy roof using Japanese-style tiles, and rainwater intrusion will be prevented by providing a pair of water-stopping ribs. And positioning of the second long roof tile stacked on the first long roof tile becomes easy.
Further, the second long roof tile is wider than the width of the long crown tile in the short direction, and includes two pairs of water stopping ribs in the longitudinal direction of the surface, the two pairs of water stopping The distance between the pair of water-stopping ribs among the ribs is preferably narrower than the width of the long crown tile, and the distance between the two pairs of water-stopping ribs of the second long roof tile is One is preferably engaged with both side ends of the long crown tile, and the other is engaged with both side ends of the second long tile roof stacked on the second long tile roof tile.
If comprised in this way, the penetration | invasion of rainwater will be prevented between the 2nd long glazed roof tiles stacked on the 1st long glazed roof tile and between the 2nd long glazed roof tiles and the long crown roof tiles placed on the 2nd long glazed roof tile be able to. In addition, it is easy to align the second long roof tile and the long crown tile during construction.

In the ridge, the first long roof tile was fixed to a predetermined base member, and the second long roof tile was stacked and fixed in order on the fixed first roof tile. The long crown roof tile is placed on and fixed to the uppermost stage of the second long roof tile, and the base member is a resin or wooden member that is locked in parallel to the purlin by the engaging member. Thus, it is preferable that the separation distance from the purlin is adjusted so as to be flush with the upper edge of the clay-like roof tile forming the tile roof.
In this way, the entire tile roof can be harmonized while taking advantage of the characteristic of the heavy tile roof in traditional Japanese houses. In addition, it is easy to eliminate the structural weakness of the roof tiles against earthquakes, repair the roof tiles, and construct new buildings.

Since the long roof tile for building of the present invention is molded from resin, it is lightweight and has sufficient strength. In addition, it is longer than conventional tiles, and can be cut to the required length according to the length of the tile roof ridge. In particular, the structural weakness of the roof tile against long-period vibration can be eliminated. In addition, construction is easy, shortening the construction period and labor when renovating or newly constructing roof tiles.

As shown in FIG. 1 to FIG. 4, the first long glazed tile 10 of the present embodiment is a glazed roof tile used for a ridge portion of a tile roof, and a resin whose length is set to 1820 mm is a main component. It is a long and lightweight roof tile. In the cross section in the short direction, the center 1 is flat and the side edges 2 are bent. The gradient of the side edges 2 is slightly larger than the gradient of the flow of the tile roof (3.5 / 10 to 5.5 / 10) sprinkled with clay pier tiles. In addition, the flat part of the center 1 and the bent part of the both side ends 2 may be continuous, or a curved part may be provided therebetween.
On the surface of the first long roof tile 10, a pair of parallel water-stopping ribs 3 are provided at symmetrical positions in the longitudinal direction, and the distance D1 between the pair of water-stopping ribs 3 is shown in FIG. It is narrower than the width W2 in the short direction of the second long glazed roof tile 20 described based on FIG.

Furthermore, since it has a length several times the normal roofing width X of the tile (here, set to 1820 mm), depending on the length of the roof of the tile roof, it can be used as it is. It can also be used by cutting to the required length. Therefore, it is possible to reduce the number of tiles in the ridge part that is formed and to reduce the weight, so that the structural weakness of the ridge tiles against earthquakes such as long-period vibrations can be eliminated, and when the ridge tiles are repaired or newly installed The construction period can be shortened and labor can be reduced. In addition, since the slope of the bent two end portions 2 is larger than the slope of the flow of the roof tile, it is possible to prevent rainwater from entering from the gap between the first long roof tile 10 and the roof tile. Furthermore, since the pair of water-stopping ribs 3 is provided on the inner side of the both side ends 12 of the second long-sized roof tile 20 placed on the first long-sized roof tile 10, It is possible to prevent rainwater from entering through the gap between the two long roof tiles 20. Then, if the distance D1 between the pair of water-stopping ribs 3 is adjusted so that the water-stopping ribs 3 are engaged with both side ends 12 of the second long roof tile 20, the rainwater can be infiltrated more reliably. In addition, it is easy to align the second long roof tile 20 during construction. Moreover, if a shallow groove 6 matching the width X is provided outside the pair of water-stopping ribs 3, the appearance will be the same as when using clay-like roof tiles, and Japanese-style roof tiles will be used. It can be harmonized with the heavy roof.
