Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roofing material for a sideboard of a long iron plate having a snowfall prevention function.

[0002]

[Prior art]

 The roofing material (utility model registration number No. 3308868) having a snowfall prevention function, which was devised by the same inventor as the present application, has a protrusion part obtained by bending a part of a horizontal thatched iron plate in a triangular shape as shown in FIG. It is a type that prevents snowfall by raising it by 25 to 30 mm.

[0003]

[Problems to be solved by the device]

 The roof material with snowfall prevention function described in the conventional technology is excellent in snowfall prevention function, appearance, and durability, but since it has a structure in which one snow stop is arranged on one roof material, If the vertical width of the roofing material is widened without changing the height of the snow stop, the ability to prevent snowfall will be insufficient for the amount of snow accumulated.

Further, if the insulation of the attic is not perfect, dew condensation may occur inside the snow stop.

Further, in the case of a steep roof, this roofing material is not preferable as a building in which the appearance is generally emphasized, because a snow stop visible from the ground stands out to some extent.

The present invention is intended to solve the above problems of the conventional technology, and its purpose is to achieve a higher economic efficiency than the conventional technology and a structure integrated with a roof iron plate. It aims to provide roofing materials that have further improved advantages such as strong snow protection, roof aesthetics, and durability.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the roofing material for a thatch having the snowfall prevention function of the present invention is a shallow gutter-shaped roofing iron plate between the lower edge contacting part and the upper edge contacting part. It is formed by forming continuous triangular protrusions parallel to the lower edge.

Regarding the shape of the protrusion, the side facing the ridge side of the roof is a substantially right angle with respect to the slope of the roof, and the eaves side is an isosceles triangle that is approximately 3/5 of the ridge side. Is doing.

The protrusion is provided at a position closer to the center of the lower edge of the iron plate by about 1/3 of the vertical width of the iron plate.

Further, the apex portion of the protrusion is not bent at an acute angle, but is somewhat rounded.

The lower edge side of this protrusion is folded back to the upper surface at a position of about 3/5 of the height at an angle of 2 to 3 ° with respect to the horizontal plane to form a roof surface on the lower edge side, and its tip end. The lower edge contacted part is provided on the.

The lower edge side roof surface is formed so as to be higher than the upper edge side roof surface that sandwiches the protrusion, apart from the lower ground of the roof.

[0013] Further, on the roof surface on the upper edge side, a fold line that is folded to the surface side is provided from the lower edge to approximately the center of the vertical width of the iron plate.

The upper edge side roof surface is formed so as to be in close contact with the lower ground of the roof, and an upper edge side contacted portion and a fixing portion following the upper edge side contact portion are provided at the tip end portion thereof.

[0015]

[Action]

 As shown in the side view of the roofing material for horizontal thatching in Fig. 2, the upper side of the high triangular protrusion prevents the snowfall by stopping the sliding of the snow on the roof, and the lower side of the protrusion has the protrusion. Since it supports the received sliding pressure of snow, it is possible to obtain a greater effect of preventing snowfall than the conventional one.

Further, by separating the roof surface on the lower edge side following the protruding portion from the lower ground of the roof, the gap between the protruding portion and the peripheral portion thereof increases.

Further, since the lower edge side roof surface has the above-mentioned structure, the lower edge side roof surface hides the protrusions and looks low when viewed from the ground on the eaves side.

[0018]

【Example】

 Examples will be described with reference to the drawings. 1 and 2, the roofing material A for lateral roofing is a long iron plate for roof having a thickness of 0.35 to 0.4 mm formed in a gutter shape by a sheet metal forming and bending machine.

More specifically, one side edge portion is bent to the back surface side in a hook shape to form the lower edge contacted portion 1.

At a position closer to the center by 70 to 80 mm from the lower edge of the lower edge side roof surface 6 following the lower edge contacted portion, the iron plate is folded and bent toward the surface side to form a protrusion 2 having a triangular cross section. Has been done.

The length of the lower edge side of the protrusion 2 is 20 to 30 mm, and the length of the upper edge side is 35 to 50 mm.

In addition, the protrusion 2 has an opening having a width of 20 to 35 mm, which connects the starting point on the lower edge side and the starting point on the upper edge side, and the surface on the ridge side is substantially perpendicular to the slope of the roof. Has been launched.

On the upper edge side roof surface 7 of the protruding portion 2, a fold line 3 formed by folding the iron plate 3 to 5 ° toward the surface side at a position about 60 mm away from the starting point on the upper edge side of the protruding portion toward the center. Has been formed.

At the other edge of the iron plate, the iron plate is bent into a hook shape to form an upper edge contacted portion 4.

A fixed portion 5 of 25 to 35 mm, which is horizontal to the slope of the roof, is formed at the end of the upper edge contacted portion 4.

[0026]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

[0027] By increasing the height of the snow stop without causing a discomfort in appearance, the number of snow stops per unit area of the roof can be reduced, and the vertical width of the roof material can be kept without impairing the snow stop function. It can be about 20% wider than the mold.

As a result, the number of contacted portions and fixed portions per unit area of the roof is reduced, the material such as the roof iron plate is saved, the efficiency of the forming work and the roofing work is significantly improved, and the sheet metal work is improved. The cost is greatly reduced.

By lowering the height of the lower edge of the snow stopper and separating the roof surface of the lower edge from the lower ground of the roof, the internal space of the snow stopper and its surroundings becomes large, and the dew condensation prevention effect increases due to an increase in the air layer. The fruit can be secured.

Further, when viewed from the ground on the eaves side, the snow stop is hardly noticeable.

Since the lower side surface with a short leg supports the snow pressure received by the upper side surface of the protrusion 2 (hereinafter referred to as snow stopper), it can withstand a large sliding pressure of snow without using a reinforcing material or the like. I can do it.

Therefore, no problem occurs even if the rising portion is raised.

By providing a fold line in the substantially central portion of the roof material, the adhesion between the roof material and the roof base material is enhanced, and the roof material is stored well.

Since the snow stopper has an integral structure with the roof material, it does not fall off, deform, or deteriorate in function.

The structure of the snow stopper is simple and prevents the occurrence of distortion and fine scratches on the surface of the iron plate due to bending.

Since the snow stopper is processed as a continuous operation when forming a roofing iron plate in a sheet metal factory, it is easy to form and is economical.

The sheet metal work for the roof using this roofing material does not differ from the usual horizontal roofing work, and does not require extra labor, special tools or members.

Since the snow stopper is integrated with the roof, there is no discomfort in appearance and the aesthetics of the building are not impaired.
