Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roof snow melting device with excellent thermal efficiency.

[Conventional technology]

Roof snow melting devices that have been implemented in the past can be roughly divided into (a) those with a heating plate attached to the back side of the roof (b) heating pipes that pass warm air or hot water over the roof or under the attic. (c) There are some types that have a double roof structure and blow hot air, but the major drawback of these is that they require a lot of fuel such as electricity and oil required for thermal energy. It was hot.

Therefore, it has been a technical challenge to provide a snow-melting roof device that does not waste heat, has excellent thermal efficiency, and does not require fuel costs.

[The problem that the idea attempts to solve]

The present invention solves this problem by installing a net member on the snow melting roof surface with a gap between the roof surface and the roof surface to create a heated air layer between the roof surface and the net member. To provide an economical roof snow melting device which improves the snow melting ability of melting snow adhering to a net member and can save fuel cost accordingly.

[Means to solve the problem]

The gist of the present invention will be explained with reference to the accompanying drawings.

A net board 2 is attached to a rectangular surrounding frame 2a, and a net member a with a support fitting 3 hanging down from the lower part of this surrounding frame 2a is placed on the top surface of the roof 1 with a gap between the top surface of the roof 1 and the net board 2 by the support fittings 3. A plurality of convection promoting plates 6 are disposed in a row in the vertical and horizontal directions through the net member a, and are formed of a top plate part 4 and a downward plate part 5 at the lower part of one side of each net member a. This relates to a roof snow melting device characterized in that convection promoting plates 6 adjacent to each other in the horizontal direction parallel to the row direction of the roof are arranged in a straight line in the length direction of the convection promoting plates 6. be.

〔Example〕

In the drawing, the upper surface of the roof 1 is left undisturbed, and a plurality of net members a each having a net board 2 attached to a rectangular surrounding frame 2a are combined to form a structure in the vertical direction (the slope direction of the roof 1) and the horizontal direction (the row direction of the roof 1). ) are arranged in a grid pattern and attached to the upper surface of the roof 1.

Supporting metal fittings 3 are provided on both sides of the surrounding frame 2a to form a parallel distance between the upper surface of the roof 1 and the net board 2 when attached to the upper surface of the roof 1.

This supporting metal fitting 3 uses a corrugated plate 3a, and this corrugated band plate 3a is attached to a long tile bar 7.

Further, an anti-promoting plate 6 consisting of a top plate part 4 and a downward plate part 5 for promoting convection of heated air is provided below one edge of the net board 2.

Each of these convection promoting plates 6 is attached to the lower part of the net board 2 facing in the row direction, and the convection promoting plates 6 adjacent to each other in the row direction of the roof 1 are arranged in a straight line in the length direction of the convection promoting plates 6 and are connected to each other. (In the drawing, the net members a are arranged in three rows in the slope direction, so the convection promoting plates 6 are arranged in three rows in a straight line in the row direction.) Also good.

The net board 2 is preferably a perforated board, a slatted board, an expanded metal board, or the like, which has air permeability and can withstand snow loads.

[Effect of idea]

Since the present invention is constructed as described above, snow falling on the net member a does not fall from the net hole onto the roof, but is accumulated on the net member a due to the adhesive property of the snow.

The snow that completely covers the top of the net member a acts as a heat insulator, keeping the space between one side of the roof and the net member a warm, and the air that has no place to escape during this time is transferred to the attic's waste heat. The heated air is heated by a heat source such as a surface heating plate or a heating pipe on one side of the roof, and this heated air is well convected by the convection promotion plate 6, and for example, it is heated according to the roof slope. Since it penetrates into the snow from the net hole while moving upward, the heat energy is used to effectively melt the snow, and since no heat is wasted, the snow melting ability is greatly improved.

In this case, as shown in Figure 2, if the net member a is installed leaving a small area around one side of the roof, the remaining area of snow will block the area around the net member a, preventing heat from escaping to the outside. This results in more effective snow melting.

Therefore, there is no waste of thermal energy, so even if a roof heating device is used, fuel costs can be saved and it is economical.

In addition, the presence of the gap between the net member a and the upper surface of the roof 1 separates the snow melt from the snow melt water, so that the snow melt water drains smoothly, and the upper surface of the roof 1 is heated even late at night. Therefore, it is possible to provide an excellent roof snow melting device that prevents snow melting water from freezing and maintains a good snow melting state at all times.
