Description

[Detailed description of the invention] [Industrial application field] The present invention relates to the improvement of a roof structure in which tiles are used as a roofing material and each of the tiles is locked to a tile bar, particularly in a snowy area. The present invention relates to a technique for reliably melting snow on a roof with a simple configuration.

[Prior Art] As is well known, a roof structure in a building using a tile as a roofing material is to fix a roof frame (main building) above a beam and lay a plurality of tiles above the roof frame. However, as a configuration of an intervening member interposed between the plurality of tiles and the roof frame, for example, the following one has been put to practical use.

That is, a field board is fixed directly above the roof frame (main building), a waterproof asphalt roofing is pasted directly above the roof board, and a heat insulating material is further covered immediately above the roofing frame. A plurality of roof tiles are laid directly above. When laying the tiles, the tiles are placed on the top surface of the heat insulating material in a predetermined order, and the tiles are driven into the roof top by driving nails and the like from above a predetermined location into the roof plate. It will stop.

In this case, a locking projection is integrally formed on the lower surface of each tile, and a tile crosspiece extending in a lateral direction (substantially horizontal direction) is fixed at regular intervals on the upper surface of the heat insulating material on the roof. Usually, the locking projections of the roof tiles are locked to the roof of the roof to ensure that each tile is prevented from sliding down.

[Problems to be solved by the invention]

By the way, in the above-mentioned conventional roof structure, although a heat insulating material is arranged directly below the roof tile, the method of using the heat insulating material alone can merely obtain a heat retaining effect, Aggressive heating cannot, of course, be performed. For this reason, in a snowy area, a large amount of snow remains on the roof, and various troubles are caused unless troublesome and complicated snow removal work such as snow removal is performed.

When a roof structure is used in which each tile is locked to a roof tile as shown in the above example, the roof structure becomes unique, but in this case, the complicated structure is unnecessarily complicated. In order to eliminate the snow on the roof without inviting and surely, it is important to consider what measures are best to take.

The present invention has been made in view of the above-described circumstances, and by adding a suitable new configuration to each of the tiles and the roof tiles, it is possible to surely reduce the snow on the roof without complicating the roof structure. The technical task is to make it possible to deal with it.

[Means for solving the problem]

A specific means for achieving the above technical problem is that, in a roof structure using a tile as a roofing material, a heating element that generates heat based on an electric signal is incorporated inside the tile, and the tile is mounted. A lead wire is incorporated into the roof tile to be locked, and a heating element incorporated in one of the tiles adjacent to the other and a heating element incorporated in the other tile are electrically connected via the lead wire. It is configured to be connected to.

More specifically, in a roof structure using a tile as a roofing material, a heating element that generates heat based on an electric signal is incorporated in the inside of the tile, and electric power is applied to both ends of the heating element on the back surface of the tile. A male terminal or a female terminal to be electrically connected is attached, an internal passage is formed in a tile bar for locking a tile, and a lead wire is housed in the internal passage. A female terminal or a male terminal which is electrically connected to both ends of the wire, respectively, and a male terminal or a female terminal at one end of a heating element incorporated in one of the tiles arranged adjacently. To the female terminal or the male terminal at one end of the lead wire so that the male terminal or the female terminal at one end of the heating element incorporated in the other tile can be connected to the other terminal of the lead wire. Female terminal or male end Lies was allowed Hamada' can fit held in.

[Action]

According to the above-described means, as a basic configuration, a heating element is incorporated in the inside of the tile and a lead wire is incorporated in the tile rail, and the heating element of one of the adjacent tiles and the heating element of the other tile are connected to each other. Since the electrical connection is made via the lead wire, a predetermined electric signal is transmitted from the heating element of one tile to the heating element of the other tile via the lead wire, and is adjacent to the other tile. Similarly, for a tile, a predetermined electrical signal is transmitted from the heating element of one tile to the heating element of the other tile via a lead wire, and thus a predetermined electrical signal is generated to the heating elements of all the tiles via a lead wire. An electric signal will be transmitted. As a result, the heating element of each tile generates heat based on the predetermined electric signal, and as a result, each tile itself is directly heated, and snow melting on the roof is performed well.
As described above, in a roof structure using a tile as a roofing material, by effectively using an existing component, a tile bar, as an installation point of a lead wire and, as a result, an electric signal transmission path, effective use of the tile bar is achieved. It is possible to reliably melt snow on the roof without causing layout problems, etc., and to reduce the number of parts as much as possible despite the addition of a snow melting configuration. Become.

As a detailed configuration, female terminals (or male terminals) electrically connected to both ends of the heating element are attached to the back surface of the tile, and male terminals electrically connected to both ends of the lead wire, respectively. Since the mold terminal (or female terminal) was attached to the surface of the tile bar, when the tile was locked to the tile bar, the back surface of the tile was placed above the surface of the tile bar. At this time, the female terminal (or male terminal) at one end of the heating element incorporated in one of the adjacent tiles becomes the male terminal (or female terminal) at one end of the lead wire. The female terminal (or male terminal) at one end of the heating element that is fitted and held and incorporated into the other tile is fitted and held at the male terminal (or female terminal) at the other end of the lead wire. It will be. As a result, one heating element of the adjacent tile and the heating element of the other tile are electrically connected to each other through the lead wire. Only by sequentially locking the roof tiles, that is, it is only necessary to place the back side of the roof tiles above the front side of the roof tiles, thereby facilitating on-site work and improving workability. Will be done.

[Effect of the invention]

Since the snow-melting roof structure according to the present invention is configured as described above, it has the following effects.

That is, according to the snow-melting roof structure of the present invention, the heating element incorporated in one of the adjacent tiles and the heating element incorporated in the other of the tiles are incorporated in the tile beam. Since the electrical connection is made via the lead wire, a predetermined electrical signal is sent to the heating element of each tile on the roof via the lead wire, so that each heating element of each tile generates heat simultaneously. Accordingly, the tiles are directly heated at once, so that the snow on the roof is melted well, and various adverse effects caused by snow in a heavy snow area are reduced as much as possible. In the roof structure using tiles as a roofing material, the existing structural elements, such as the roof tiles, are used as the installation points of the lead wires and, as a result, the electric signal transmission paths, so that the roof tiles can be effectively used. This makes it possible to reliably melt the snow on the roof without causing a layout problem or the like, and to suppress an increase in the number of parts.
