Description

[Detailed description of the invention] This invention relates to a roof for snowy areas. The purpose is to melt snow that has fallen on the roof and propose a roof for snowy areas that does not require snow removal.

ALC panels (autoclaved lightweight concrete panels) are lightweight and have high thermal insulation properties, making them ideal for roofs in cold regions. However, in snowy regions, the load of snow on the roof is large, and conditions are not favorable for using ALC panels. In addition, it requires a lot of effort to remove snow that has accumulated on the roof, and removing snow from the second or higher floors is dangerous, so a solution was desired. This invention was made in consideration of the above circumstances.

This will be explained below with reference to the illustrated embodiments.

The ends of the H-shaped steel beams are butted together on the ALC plates.
The roof is constructed by laying ALC panels 2,
A long hot water pipe 3 is provided on the upper surface of the 2.
A copper plate 4 is laid on the surface. The hot water pipes 3 are laid in grooves drilled in advance on the upper surface of the ALC plate 2, and mortar 5 is filled in from above to bury them. Both ends of the hot water pipes 3 buried in each ALC plate 2 are
The ALC plate 2 is connected to a hot water circulation system (not shown) disposed on the underside of the plate. The two copper plates 4, 4 have their adjacent edges butted together and raised, and a retaining clip 6 is fixed between them with an anchor bolt 7. The copper plate 4, the retaining clip 6, and the end edges of the copper plate 4 are overlapped and fixed, and a cap 8 is attached.
It is connected by covering it with a

This roof has the above structure, and the ALC board has low thermal conductivity, so the heat radiated from the hot water pipes installed on the top layer is hardly conducted to the bottom layer, and the thermal conductivity is low.
Most of the heat is radiated to the top side through mortar that is approximately 10 times larger than that of the ALC board. Further, since metal plates such as copper plates are laminated on the surface, the heat is transmitted to the metal plates and raises the temperature of the metal plates. Therefore, when snow accumulates on a sloped roof, by passing hot water through the hot water pipe, the lower surface of the snow accumulated on the roof can be melted and allowed to slide off, eliminating the need for snowfall.

ALC board has excellent workability and can be easily processed using cutting tools, so it is easy to drill grooves and install and bury hot water pipes at the construction site. Moreover, if predetermined grooves are drilled in advance at a factory or the like, construction efficiency at the construction site can be further improved.

In addition, the ALC board used for this roof is reinforced with reinforcing steel 9
are placed only on the bottom layer, and there are no reinforcing bars on the top side, making it possible to bury long hot water pipes.

It goes without saying that the ALC plate surface can be selected from a copper plate, a stainless steel plate, a galvanized iron plate, and the like.

This idea is as described above, and brings about the following effects. It has high heat utilization efficiency and uses hot water as a heat source, so it can use inexpensive fuel and is cheaper than heating with an electric heater.
It is easy to bury the hot water pipes in the ALC board and the construction cost is low. This reduces the load on roofs caused by snow, making it possible to use ALC boards on rooftops in snowy areas. In this way, the roof of this invention can take full advantage of the light weight and high thermal insulation characteristics unique to ALC boards in snowy areas.
