BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure for preventing snow from rolling down. More specifically, the present invention relates to a snow roll-over phenomenon and a large amount of snow occurring at the eaves of a snow-covered roof, especially above a front entrance or a valley of a roof. The present invention relates to a roof structure for preventing snowfall.

2. Description of the Related Art As is well known, various phenomena occur in a snow layer on a roof in a snowy area depending on environmental conditions such as temperature, humidity, solar radiation, and wind speed. A phenomenon referred to as curling may occur. As shown in FIG. 7, this undulation is accompanied by icicles B1 generated at the tip of the roof A of the building without the snow layer B on the top of the roof A being cut off at the eave tip A1.
This is a phenomenon of being bent so as to be wound toward the vertical wall surface A2 of the building. Such a phenomenon occurs not only in a building having a sloped roof A as shown in the figure, but also in a building having a flat roof.

[0003]

[Problems to be solved by the invention] By the way, if the snow layer rolls as described above, the eaves are broken, the gutter falls, the vertical wall is broken, the glass is broken, the shed is damaged, and personal injury is caused. In addition to causing adverse effects, such as shown in FIG.
An ice levee C is formed on the upper surface of the eaves tip A1 of the roof A, and a water reservoir D is generated directly above the eaves C. This causes so-called spillover E to occur. For this reason, it is essential to prevent the occurrence of the slop in advance in avoiding snow damage in a snowy area. However, in order to avoid the above-mentioned problems, simple measures such as dropping the rolled part from below are usually taken.In this case, a large amount of snow falls during the work of dropping. This causes a secondary disaster, such as the worker being underneath. In this case, falling icicles and ice blocks are particularly dangerous, and may cause a serious injury. In particular, regarding the adverse effects of personal injury caused by heavy snowfall, it is easy to occur in places where the frequency of traffic is high, such as entrances, and it is necessary to prevent the danger of such accidents occurring beforehand. This is a very important issue in the architectural design field. Therefore, conventionally,
As shown in FIG. 8, in consideration of the direction of the slope of the roof, the sliding direction of snow (the direction indicated by the arrow in FIG. 8) is prevented from reaching above the entrance, so that the traffic of the pedestrian around the entrance is reduced. In order to protect the roof, the roofing material was taken into consideration, or a snow stopper was added, and further, a snow split was provided. However, according to such means, it is necessary to take into account the roof main body, so that the cost must be increased, and the appearance is uniquely determined, and furthermore, there is a problem that it is not suitable for a wide range. In addition to this, there is also a problem that a large amount of snow falls in other parts because only the direction in which the snow falls is changed. In addition, the occurrence of rolling and a large amount of snow fall are likely to occur in a portion where a snow layer is stored, such as a valley of a roof, and it is also necessary to prevent such a situation from occurring in the same manner as described above. This is an important issue.

[0004] The present invention has been made in view of the above circumstances, and causes the roof to roll over in a snowy area or a large amount of snowfall, especially above a location where the frequency of traffic is high or a location where the amount of snowfall increases. Provide an inexpensive roof structure that can prevent dripping and mass snowfall beforehand and that can be easily installed without significantly affecting the appearance, and eliminate various adverse effects caused by rolling and mass snowfall. Avoidance is a technical task.

[0005]

The roof structure for preventing snow from rolling down according to the present invention, which has been made to solve the above technical problems, has the following features. That is,
At least an end portion of the roof located above the passage frequent large portion of the human, or to attained partial snow winding sagging end of the roof of a portion at least amount of snow increases
At the end of the roof at the overlap of the roofing material
When the extension at the lower end of the standing post is inserted and fastened
In addition, the effects of solar radiation and temperature extending laterally between the
Stretch multiple stretched struts made of material that can be received and warmed
It was passed .

[0006]

According to the above-mentioned means, when a snow layer is formed on the upper surface of the roof, the snow layer grows and protrudes outward from the edge of the roof. It is cut by a plurality of tension strips stretched between the upright supports above the ends and falls early. In other words, when the snow layer protrudes as described above, a shear force is generated on the arrangement surface of the tension strip by the own weight of the protruding portion,
As a result, the protruding portion is cut and dropped.
In addition, since the stretched strip itself is heated under the influence of solar radiation and temperature, snow melting occurs at the contact point between the snow layer and the stretched strip, which promotes the early cutting of the protruding part. You. Therefore, the roll-up of the snow layer disappears at the initial stage of its occurrence. And especially at the edge of the roof, which is located above places where people
Is at least at the edge of the roof where the amount of snow is large
As it is possible to prevent the snow from falling down,
The configuration minimizes the possibility of personal injury caused by the occurrence of rollover, and also prevents the occurrence of rollover and, consequently, the large amount of snowfall in areas where the amount of snow is large, such as the valleys of roofs. Will be done.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the appearance of a first embodiment of a snow-melting roof structure according to the present invention. A pair of eaves tips 2a of a roof 2 located above an entrance 3 of a building 1 are spaced apart from each other. The upright supports 4 and 4 are fixedly provided.
A plurality of wires (stretched strips) 5... 5 are stretched between the four. In this embodiment, the entrance 3 is selected as a place where the frequency of traffic is high. However, in the same manner as described above, the erecting pillar 4 is located above a place where the frequency of traffic is high, such as the entrance. 4 and wires 5... 5 may be provided.

The above roof structure will be described in detail with reference to FIG.
As shown in FIG. 7, a field board 8 is stretched over roof frame members (main building) 7 ... 7 fixed to the climbing beams 6, and an asphalt roofing 9 is stretched over the field board 8. In addition, roofing materials 11... 11 made of tiles and color vests are laid above the asphalt roofing 9. The mounting structure of the upright support column 4 is not particularly limited, but has, for example, the following structure.

That is, the upright support 4 is attached to the overlapping portion of the roofing materials 11, 11 vertically adjacent to each other at the eave tip 2 a of the roof 2.
The extension portion 4a connected to the lower end of the base 4 is inserted, and the extension portion 4a of the upright support 4 and the roofing material 11 are integrally fastened to the base plate 8 using fastening members 12 and 12 such as nails. It was made. In this way, not only can the upright supporting columns 4 be securely fixed using the existing fastening members 12, 12 for fastening the roofing board 11, but also problems such as water leakage can be prevented and Deterioration of appearance can be avoided.

Next, the operation of the first embodiment will be described.
As shown in FIG. 3, when a snow layer X is formed on the top surfaces of the roofing materials 11... 11, the snow layer X is affected by its own weight, wind, and the like. 11 ... 11 grows along the upper surface, and as a result, the snow layer X
Will protrude outward from the wires 5. In this case, a shear force is generated at the portion indicated by the imaginary line Z where the wires 5... 5 are disposed due to the weight of the protruding portion X1 of the snow layer X, and due to this, the protruding portion X1 is generated.
Is cut and dropped as shown in FIG. This is because the characteristics of the snow layer X do not have sufficient strength against the shearing force, and mainly due to the characteristics that snow is soft and brittle. Also,
Since the wires 5... 5 themselves are heated under the influence of solar radiation, temperature, and the like, snow melting occurs at the contact portion between the snow layer X and the wires 5.
The early cutting of 1 is encouraged. Therefore, even if the snow layer X attempts to grow outward from the wires 5... 5, there is a limit to this growth, and when the slight protruding portion X1 is generated, it is protruded by the cutting action of the wires 5. The portion X1 does not fall and does not grow until the occurrence of the curling as shown in FIG. 7 described above. In particular, in the above-described embodiment, there is no occurrence of hanging over the entrance, and therefore, even if a person frequently enters and exits the entrance, there is a problem that the hanging part having icicles falls on the person. Is avoided, and the occurrence of personal injury due to the roll-up is reduced as much as possible. In addition, as shown in FIG. 5, there is also obtained an advantage that a large amount of snowfall can be prevented from reaching the approach 3a, which is a passage leading to the entrance 3. In the above embodiment, the present invention is applied to a gable roof, but the present invention can also be applied to a ridge roof and a flat roof.

FIG. 6 shows a second embodiment of the snow melting roof structure according to the present invention.
The exterior of the embodiment is shown, and a plurality of upright supports 4 are provided at the tip of the eave around the valley 2x of the roof 2 where snow tends to accumulate.
.. 4 are fixed, and wires 5... 5 are stretched over these upright supports 4. According to this,
The valley 2x of the roof 2 due to the snow blocking action of the wires 5 ... 5
In addition to avoiding the problem that a large amount of snow that has accumulated on the ground falls at once, the occurrence of roll-up does not occur in the same manner as described above.

Incidentally, the wires 5...
The method is not limited to using a simple metal wire, a resin wire, a glass fiber wire, or the like. For example, the snow layer X may be heated and cut or melted by using a heating wire. A provision means may be added to cut and drop the protruding portion X1 of the snow layer X earlier.

[0013]

[Effects of the Invention] As described above, according to the roof structure for preventing snow from rolling down according to the present invention, the snow layer formed on the upper surface of the roof grows outward from the tension strip between the upright supports. In the case of protruding, the protruding portion is cut and dropped by the action of the tension strip, and does not grow until the occurrence of curling. In particular, it is possible to prevent the occurrence of drooping above a place where people frequently pass, such as an entrance, and the likelihood of a dripping part having icicles falling onto a person is reduced as much as possible. The probability of occurrence is reduced, safety is improved, and a large amount of snow falling from a place where snow easily accumulates, such as a valley of a roof, is prevented. Further, since the structure is simple, it is inexpensive, does not impair the appearance, and can be retrofitted, so that it can be widely applied. Furthermore, between the upright columns
Stretched and stretched to the sun and temperature
Made of material that can be heated under the influence of
Snow melts at the contact point between the tension strut and the snow layer and protrudes.
Early cutting of the part is promoted.
