DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow-less roof unit for preventing collapse of a house due to the weight of snow and disaster such as personal injury caused by falling snow.

[0002]

2. Description of the Related Art In a snowy area, since the amount of snow covers several meters, a house collapses due to the weight of snow or a disaster such as a personal injury due to falling snow occurs, so that snow removal on a roof is inevitable. Conventionally, snow removal on roofs has first relied on human power, but this requires not only a great deal of labor, time and expense, but also has problems such as poor workability, inefficiency, and danger. Was. Next, as a snow removing means which does not depend on human power, the roof shape was simplified, the gradient was increased, and a material having excellent snow sliding property was selected for the roof material itself. However, since all of these snow removal methods rely on natural snow sliding, it is necessary to dispose of snow falling on the ground to, for example, rivers, vacant lots, and other places, which requires a great deal of labor, time, and There were problems such as costs.

[0003] Recently, a snow collecting apparatus has been proposed which compensates for the disadvantages of the above snow removing means (see, for example, Japanese Utility Model Laid-Open No. 62-187022). Its outline is shown in Figure 6.
The upper end opening d of the snow collecting gutter c is opened at the inclined lower end of the roof structure b in the building a, and the snow collecting gutter c is located substantially at the center of the building a. A vertical snow gutter e and a horizontal gutter f extending from the lower end thereof to the outside of the building a, and furthermore, a snow melting machine g formed by a heater, a boiler or the like at an appropriate position of the gutter c. This melts the snow in the snow collecting gutter c and discharges it from the opening h to the ground and other desired places.

[0004]

However, in the above-mentioned snow collecting apparatus, since a gutter must be provided in the center of the building and sheet metal work is carried out on site, other buildings and roofs are not provided. Higher skills of craftsmen were indispensable, as they required more careful and laborious work than necessary. The present invention has been made in order to solve the above-described problems, and by using a construction method capable of minimizing variation in construction accuracy by manufacturing a unit housing, a snow-free roof with a reliable installation is provided. It is intended to easily realize the unit.

[0005]

SUMMARY OF THE INVENTION A snow-free roof unit according to the present invention.
Units are mounted on top of multiple living room units.
In a unit building equipped with
The units are linked together to form a pair of continuous sloped roof surfaces
And the pair of sloped roof surfaces are M-shaped in side view.
Buildings that are symmetrically arranged facing each other, and whose roof surfaces face each other
A straight gutter is provided at the center of the gutter, and a part of the gutter is provided.
Is provided with a downspout with snow melting means
No snowfall roof unit.

Further, the snow-free roof unit of the present invention is
A gutter is pre-installed in the center of the roof unit,
It has a roof surface into which rainwater flows from the side toward this gutter
It is characterized by using a roof unit,
This gutter is located between the roof units and
It is installed so as to straddle the underwater end
The unit has no snowfall roof.

Further, each of the above-mentioned opposed sloped roof surfaces
The continuous roof surface is a floating roof on the edge of the roof unit under the water.
Adjacent with the ends of the root units covered
A snow-free roof unit characterized by the following features.

[0008]

[0009]

Since the snow-free roof unit according to the present invention is constructed as described above, snow falling from the roof is prevented. In addition, by using a construction method that minimizes variations in construction accuracy by factory production of unit houses, a snow-free roof with a reliable installation can be easily realized.

【Example】

An embodiment of a snowless roof unit according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention. The unit building 1 is configured by mounting six roof units 3 on the upper surface of twelve living room units 2. Each living room unit 2
For example, a frame is assembled from lightweight steel and the frame
Floors, ceilings, walls, and various other equipment are installed as necessary, and the interior and exterior are finished. Each roof unit 3 also
At a factory, a frame such as a truss structure is assembled with, for example, lightweight section steel, roof materials are attached, and both inside and outside are finished. The roof structure is composed of roof units 3a and 3b arranged in the left and right directions and a roof unit 3c arranged in the center, and is inclined down from the left and right ends 1a and 1b of the building 1 to the middle part with a required gradient. . Roof unit 3
c has a gutter-shaped shape 4 at the center, an opening 5 is provided at the center, and a gutter 6 is incorporated in advance.

FIG. 2 is a detailed view of FIG. 1A. A plywood roof surface material 8 is fixed to the frame 7 of the roof unit 3, and a waterproof paper 10 is interposed between the roof surface material 8 and the iron plate roof material 9 to prevent rain and snow from entering. I have. The roofing material 9 is joined with a roofing material joint iron plate 11. A waterproof sheet 13 is adhered to the unit joint portion 12 in order to further complete the rain.

FIG. 3 is a sectional view taken along the line BB of FIG.
The downspout 6 is communicated with the downspout 14 at the opening 5, and a snow melting machine 15 formed by a heater, a boiler, or the like is provided at an appropriate position of the downspout 14, thereby melting the snow in the downspout 14. The snowmelt can be discharged to the desired location. Downspout 1
4 is erected using the gap between the living room units 2. A rising 16 is provided at an end of the underwater roof unit 3c, and an end 17 of the underwater roof unit 3b covers the upper end of the rising 16, so that the underwater roof unit 3c Intrusion of rain and snow from the boundary with the roof unit 3b on the water side can be prevented.

The details are shown in FIG. FIG.
FIG. 3C is a detailed view of a part C. Roofing material 9 for roof unit 3c
A dry type sealing material 14 such as a sealer, which is a dry type waterproofing material, is interposed between the roof unit 8 and the roof surface material 8 of the roof unit 3b. I have.

FIG. 5 shows another embodiment of the present invention. The horizontal gutter 6 is inserted between the roof units 3 and 3, and the vertical gutter 14 is erected using the gap between the living room units 2 and 2. A snow melting machine 15 formed by a heater, a boiler, or the like is provided at an appropriate place of the downspout 14, thereby melting the snow in the downspout 14 and discharging the melted snow to a desired place. This is the same as the previous embodiment.

[0016]

According to the present invention, since a snow-free roof is formed by appropriately combining a plurality of roof units, it is possible to prevent the collapse of a house due to the weight of snow and to prevent a disaster such as a personal injury caused by falling snow. Can be.

In addition, since a construction method of minimizing variations in construction accuracy by using factory production of unit houses is used, sheet metal work requiring skill on site can be avoided, and a snow-free roof unit with a reliable installation can be easily manufactured. Can be realized.

Further, the snow accumulated on the roof is collected by a gutter and dropped, and is melted and discharged to an appropriate place on the ground or the like during the falling process. Is no longer necessary, and the snow on the roof is not immediately melted on the spot, so that the energy for melting the snow is relatively small and economical.

The roof unit joint in the direction of taking the water gradient has a structure in which a rising is provided at an end of the roof unit below the water, and an end of the roof unit above the water covers the upper end of the rising. Since a dry seal material is interposed in the unit joint, rain and snow can be reliably prevented from entering the unit joint.
