DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure of a gabled building, and more particularly to a waterproof and drainage structure of a flat-plated metal plate roof.

[0002]

2. Description of the Related Art A wooden building has a structure shown in FIG.
As shown in FIGS. 0 (a) to (c), they can be classified into gables (a), ridges (b), gadgets (c), and the like. These roof shapes are based on geographical conditions (temperature, rainfall, snowfall, history)
It changes variously depending on the size of the house and the house. Similarly, materials and shapes of roof materials (tiles, slate, metal plates, etc.) vary in accordance with geography and climate.

[0003] The present invention mainly relates to a gable roof, which is a flat-plated metal plate (so-called tin roof).
The gable roof is characterized by its simple shape, and is an effective means for reducing construction costs. Especially in snowfall areas, gable roofs are often used because it is necessary to quickly drop roof snow. It is effective to use a metal plate as a roof material in order to balance the weight of the roof and the construction cost according to the amount of snowfall. It is for this reason that wooden buildings in Hokkaido and northeastern Tohoku use gables and tin roofing. The fact that tile roofs are seen in the Hokuriku region, where snowfall is high, is thought to be a result of the historical background of technology transmission.

[0004] On the other hand, there are various types of metal-plated roofs depending on the size and goby shape of the metal plate. In the old days, the processing of goby, which succeeds a flat metal plate, was often done manually by sheet metalwork, and the size was at most about 40 cm on a side. In recent years, however, long metal plates have been used due to advances in machine tools, and tin roofing has become much more efficient.

FIGS. 11 and 12 exemplify the shape of a roof using a long flat metal plate 1. There are two types of roofs depending on the direction in which goby 2 is inherited. On many sloping roofs (gable, single-sided, overtopping roofs, etc.), the goby 2 is run parallel to the gable 3. This is because terminal processing of gables is relatively easy, and there is an advantage that rainfall and snowfall can be quickly dropped to the flat side (Hiragana; direction of arrow H). Goby 2 _-1 in this case, general surface 5 Tin
It often has a stepped shape with a height of several tens of millimeters. Goby 2 _-1 with a high step is because it is easier to machine.

On the other hand, in the case of a joint parallel to the eave 6 as shown in FIG. 12, a goby having a step cannot be used. Metal plate 1 _-2 this case has a shape as shown in FIG. 13 when viewed from the side, parts of goby 2 _-2 downward rain and snow (arrow I
Direction), the flow step is determined according to the gable gradient. Reference numeral 7 denotes a purlin, 8 denotes a rafter, 9 denotes a ridge, 11 denotes a base plate, and 12 denotes a roofing (waterproof sheet; for example, asphalt felt).
Numeral 14 is a Kasagi, and numeral 15 is a ridge package. The cap 14 is a means for fixing the uppermost flat metal plate 1 by surface pressure.

[0007] Such a roof structure is characterized in that rain or snow is simply flown to the flat side. The entrance (entrance) of the gabled building has a flat entrance (arrow T direction in FIG. 10) and a wife entrance (arrow U direction in FIG. 10). However, the conventional roof structure all drops water to the flat side. In particular, it was not necessary to consider drainage, especially for wife's houses. In addition, when dropping water on the flat side, it is only necessary to arrange rain doors parallel to the eaves.

[0008]

However, such a conventional roof structure has a problem that the construction is complicated and it is difficult to reduce the construction cost. The reason is as follows.

First, in order to reduce the cost, it is desirable to use a machined long metal plate. However, even in this case, the gable (keraba) is contained, that is, the caulking ( It is difficult for a so-called amateur carpenter to roof the roof because of the skill required for the folding molding. Inadequate roof waterproofing can have a significant adverse effect on living spaces and houses. For example, recently, various log houses that are easy to assemble have been proposed, and it is known that short-term, small-sized houses can be built on their own. (Sheet metal or carpenter).

FIG. 14 shows an example of the settlement of the kerb.
This shows the simplest structure of the flap,
1 is projected outward from the gable plate 10, and a draining plate 41 is formed at the end of the roofing plate (the flat metal plate 1) via the contact plate 30. The draining plate 41 is formed on site, and caulking of this portion is an operation requiring skill. The symbol K is a caulking material, and F is an eave ceiling. If the construction around the draining plate 41 is insufficient, not only does the appearance of the house become extremely poor, but it also causes gables and early deterioration of the eaves ceiling.

Second, there is a problem of the direction of the splicing of the metal plate and drainage. Even if a long metal plate having a high convexity step is used for the goby for cost reduction, workability is poor if the direction of the goby joint is vertical as shown in FIG. When hitting the vertically arranged metal plate 1 on the ground board, it is necessary to move a person from the lower end (eave side) to the upper end (ridge side), and it is impossible to work alone by leaning the ladder on the eave. Because. In addition, when running vertically in the goby direction, there is a concern that, in winter, snow and ice masses piled on the roof may fall and injure pedestrians and the like under the eaves. For example, if it is assumed that an assembling house such as a log house is sold as a kit, there is a possibility that a product management responsibility (a responsibility based on the PL law) may be questioned when an accident occurs due to a goby running vertically. .
In addition, the problem of the directionality of the roof goby, which has been relatively unprotected in the past, has recently been taken into consideration such as disposing a snow stopper block on the roof for safety against pedestrians. However, snow block is expensive and construction is not easy.

Therefore, it is desirable that the convex goby of the tin roof run horizontally parallel to the eaves. This makes it easier to strike the metal plate safely, and there is no disadvantage in cost. However, when a convex goby runs parallel to the eaves, rainwater and snowmelt water cannot flow straight down, but instead flow down to the wife side (gable plate side / keraba side) and fall.

If the entrance of the house has a flat entrance structure,
Raindrops may flow down to my wife. However, in order to secure a large space habitability in a small site area like an assembling house, it is required to adopt a wife-in-house structure with an entrance on the wife side. In this case, a wife with an entrance door is required. If raindrops or snow water run down to the side, the comfort of life can be significantly impaired, and in the case of kit products in particular, the quality itself can be a basic defect.

Therefore, an object of the present invention is to provide a gable building (inclined roof; including one-sided, overtopping, inviting, and sawing), while ensuring the simplicity of the roof and the safety of construction, and at the same time, ensuring that rain on the This is to prevent snowfall.

[0015]

In order to achieve the above-mentioned object and to solve the problem, a roof structure according to the present invention comprises a flat plate portion covering a top surface of a side edge portion of a roof having a field board stretched over a predetermined width. A drainage plate having a substantially L-shaped cross section having a rising portion that rises substantially perpendicularly from the edge of the flat plate portion on the gable plate side is installed on both sides of the roof, and the rising portion is fixed to the upper portion of the gable plate. A covering plate for covering the drainage plate and the drainage by placing the end of the metal plate on the flat portion of the drainage plate and abutting the drainage plate while contacting the rising portion with the end of the metal plate. Is arranged on the wife's face.

[0016]

In the roof structure of the present invention, in order to facilitate the work of hitting the metal shingle and to ensure the safety during construction, the roof of the roof ridge runs parallel to the eaves (sideways) from the eaves. Laying metal sheets sequentially toward. On the other hand, if the convex goby runs parallel to the eaves, rainwater and snowmelt water will not easily flow downward, but will flow toward the wife side (gable plate side / keraba side).

Therefore, in the present invention, rainwater is prevented from flowing down to the wife's face by installing drainage plates having a substantially L-shaped cross section on both sides of the roof. The drainage plate is provided with a rising portion which is flush with the stiffness fixed on the top of the gable plate, and the rising portion dams the water flowing to the wife side and quickly flows down to the flat side. The drainage plate further has a flat plate portion covering the end of the base plate (roof base) over a predetermined width, and water can enter the lower surface of the metal plate from between the rising portion and the edge of the metal plate. Even if it does, the water that has penetrated flows down the flat plate upper surface toward the eaves, and rainwater does not enter the roof base.

When the metal plate is to be roofed, the drain plate may be installed on both sides of the roof, and then the metal plate end may be placed on the flat plate portion of the drain plate and placed in contact with the rising portion. No complicated processing of the roof edge is required, such as caulking (bending) the edge of the metal plate at the gable (gust).

After the metal plate is further laid, a wrapping plate is provided for the gable. This wrapper wraps the drainage plate fixed on the top of the gable plate and the drainage plate from the wife side. By providing such a wrapper plate, it is possible to prevent rainwater from entering the lower surface of the drainage plate (roof base) from the wife's side. Can be done.

[0020]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 9 show an example of a metal plate roof structure according to the present invention. As shown in the figure, the roof structure is such that a long metal plate 21 is sequentially roofed from the eaves 6 to the purlin 9 so that the convex goby 2 of the metal roofing plate 21 runs parallel (sideways) to the eaves. In the figure, reference numeral 17 denotes an eave (eave) that is installed above the fascia, 22 denotes an eaves board that covers the eaves 17, and 18
Is a dod (gable dod) fixed on the upper part of the gable plate 10. Eaves plate 22, together comprise the upper engaging portion 22a to apply a lower goby 2 _-0 lowermost Fukiita, hook-shaped turned-back portion 22
b is provided at the lower end. Note that a waterproof sheet (for example, asphalt felt) is attached to the upper surface of the base plate 11.

The length of the roofing plate 21 is set substantially equal to the width of the eaves. A drainage plate 23 having a substantially L-shaped cross section is installed on both sides of the roof, and the roofing plate 21 is placed between the drainage plates 23. Distribute.
The roof 2 has a stepped shape with a height of several tens of mm (for example, 30 to 40 mm) from the general surface 5 of the zinc. This is because a goby having a high step is easy to machine and can reduce the cost of forming a roof. In addition, it is possible to prevent ice and snow that has accumulated on the roof from sliding down during the winter season, and it is possible to ensure safety for pedestrians under the eaves without arranging snow stoppers or the like on the roof.

The drainage plate 23 has a flat plate 23a covering the side edge of the roof base, and a rising portion 23b which stands substantially perpendicularly from the gable side edge of the flat plate 23a to close the end of the roofing plate 21b.
The rising part 23b is positioned so as to be flush with the gable dust 18. Further, a wrapping plate 24 is provided on the wife's face. The wrapping plate 24 includes the rising portion 23a of the drainage plate 23 and the
Is wrapped from the wife side, and the end of the roof plate 21 (the contact portion of the roof plate 21 to the rising portion 23b) is covered like an eave. It is possible to prevent infiltration of rainwater into the lower surface (base of the roof) and prevent rain from directly blowing into the roof from the end of the roofing plate 21 abutted on the rising portion 23b. In addition, the eaves board 22, the drainage board 23, and the wrapping board 24 are formed of a metal plate (for example, a tin) similarly to the roofing board 21.

The construction procedure of this roof structure is as follows. A waterproof sheet is stuck on the surface of the base plate 11. As shown in FIGS. 4 and 5, the eaves plate 22 is attached to the dovetail 17. At this time, the folded portion 22b is brought into contact with the lower surface of the dodge 17 without any gap, and the nail is hit and fixed from the eaves surface. As shown in FIG. 6, drain plates 23 are attached to both ends of the gable. In this embodiment, the drain plate 23 is formed by joining two plates 23 _-1 and 23 _-2 at one gable end to facilitate construction. Incidentally, considering that the greater the amount of water down the more downward flow, compared to the upper plate 23 _-2, the lower plate 23 _-1
The width of is increased. When installing, the lower plate 23
_-1 is attached first, and then the upper plate _23-2 is fixed to the lower plate by overlapping a predetermined length (reference numeral 23c). In addition, as shown in FIG. 7, the rising portion 23b is positioned flush with the gable dust 18.

The metal plates 21 are sequentially goby-jointed and roofed from the eaves to the purlin. The nail S for fixing is hit from the upper surface of the metal plate, and is used for the slack 8. The topmost roofing plate is fixed by a cap 14 (FIG. 2), and the ridge 15 is attached. The wrapper 24 is placed on the wife's face. The wrapping plate 24 is the drain plate 23
Similarly, two plates 24 _-1 and 24 _-2 for one gable end
The tip is aligned with the eaves surface (the tip of the bottom roofing plate), and the lower plate _24-1 is first installed. Next, the upper plate _24-2 is attached with its upper end aligned with the ridge surface. Note that a caulking material may be interposed between the drainage plate 23 and the wrapping plate 24 in order to achieve more complete waterproofing.

According to the present roof structure, there is no need to perform complicated on-site processing such as caulking a metal plate at the roof edge.
Even a person who does not have a special technique regarding a metal roof can easily roof the roof. Since the work only needs to be nailed and attached to each of the above members in order, it is possible to efficiently construct a metal roof even with a small number of people. For example, if this roof structure is applied to a house that can be built on its own, such as a log house that is easy to assemble, the entire process including the roof formation can be performed by itself without relying on professionals such as sheet metal work and carpenters. It becomes possible.

Also, unlike a roof that runs a convex goby in the vertical direction (at right angles to the eaves), it is not necessary for an operator to move the roof up and down when hitting a metal plate on a field board, thereby ensuring safety during work. The nature is also high. In addition, since the convex goby of the roofing plate is formed parallel to the eaves, it is possible to prevent accidents in which ice and snow on the roof fall in winter and damage pedestrians under the eaves. Furthermore, since the drainage plate and the wrapping plate can reliably prevent rainwater from flowing to the wife's side and inundation into the roof foundation, there is no inconvenience caused by providing an entrance opening on the wife's side, and it is limited. A large and comfortable living space can be formed in the site area.

In the above-described embodiment, a roof plate having substantially the same length as the eave is used. However, for example, when the eave is long, a plurality of the roof plates may be connected in a horizontal direction (parallel to the eave) to be roofed. Absent. Further, in the embodiment, the drainage plate (23) and the wrapping plate (24) are formed by joining two plates for one construction part (gable end), but one continuous piece from the eave to the ridge is formed. The drainage plate or the wrapping plate can be constituted by a plate, or three or more plates can be connected and formed. Furthermore, the gabled building referred to in the present invention includes sloped roofs such as one-sided, overtopping, inviting, and sawing, and the present invention is applicable to these roof shapes.

[0028]

As described above, according to the metal plate roof structure of the gabled building according to the present invention, the roof of the gabled building can be secured to the gable side while the simplicity of the roof and the construction safety can be ensured. Rainfall can be reliably prevented.
