Description

[Detailed description of the invention] [Industrial application field] The present invention relates to improvement of a roof structure using a tile as a roofing material, and particularly reliably melts snow on a roof in a snowy area with a simple configuration. It is related to the technology to make it work.

[Conventional technology]

As is well known, a roof structure in a building using a tile as a roofing material is one in which a roof frame (main building) is fixed above a beam and a plurality of tiles are laid above the roof frame.
As a configuration of the 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. Then, when laying the tiles, while placing each tile on the upper surface of the heat insulating material in a predetermined order, driving each tile on the roof upper surface by driving a nail or the like into the field board from above a predetermined location of the tile. It will stop.

In this case, tiles having various shapes and materials have been put to practical use as the above-mentioned tiles, but these are roughly classified into Japanese tiles and Western tiles.

[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.

Then, when Japanese tiles or Western tiles are laid on the upper surface of the heat insulating material as in the above example, the roof structure, particularly the structure between each tile and the heat insulating material, is unique, but in this case, In order to eliminate the snow on the roof reliably without complicating the structure, it is important to consider what measures are best to take.

The present invention has been made in view of the above circumstances, and by effectively utilizing the space below a tile when laying a tile and adding a new configuration, the roof can be securely and securely constructed without complicating the structure. The technical task is to make it possible to deal with snowfall.

[Means for solving the problem]

As a specific means for achieving the above technical problem, in a roof structure using a tile as a roofing material, a space below the tile, a heating element in an inner hole, and a plurality of pieces on a peripheral surface. The blower tube with the through-hole is arranged so as to extend in the vertical direction from the eaves part toward the ridge part.

In this case, as a supplementary means, it is preferable that the lower space is a space extending vertically below the raised portion of the tile in a state where a plurality of tiles are laid.

[Action]

According to the above-described means, as a basic configuration, a heating element is provided in an inner hole in a space below a tile in a laid state, that is, in a gap formed between asphalt roofing or a heat insulating material and a tile above a base plate, and has a peripheral structure. Since the blower tube having the surface and the through hole formed therein is disposed so as to extend in the vertical direction, the heating element is heated, and air is forcibly supplied to the blower tube, so that the inside of the blower tube is formed. Hot air (hot air) warmed by the holes is jetted into the lower space through a plurality of through-holes formed on the peripheral surface thereof, and accordingly, the roof tiles covering the lower space are warmed, As a result, snow melting on the roof is performed well. In this way, in the roof structure using tiles as roofing material, the space under the existing tiles is effectively used as a place for installing the air duct, so that the place for installing the air duct on the roof is separately provided. There is no need to provide such a structure, and it is possible to efficiently perform snow melting on the roof without incurring an increase in the complexity of the structure and the cost, thereby reducing the adverse effects of snow on buildings in a snowy area as much as possible.

Further, as a configuration accompanying the above, if a space extending vertically below the raised portion of the tile in a state where a plurality of tiles are laid on an upper surface of a heat insulating material or the like is the lower space described above, The blower pipes are arranged in the widest space below the space, and even if the blower pipes are relatively thick, they can be reliably housed in the lower space. The amount of heat generated can be greatly increased.

In addition, as the arrangement density of the blower tubes, the blower tubes may be provided for each vertical row of the tile, or one or several rows may be opened and the blower tubes may be provided at predetermined row intervals. It is only necessary to arrange the number of air ducts according to the required total heat quantity, and therefore, it is possible to cope with the difference in temperature and the difference in the amount of snow and the difference in area.
