Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is called a "Minokou" roof, and is used for a roof plate and a Minoko shell for a Mino-ko that is applied to a roof with a curved shape at the end on the gable side of a shrine or temple. The present invention relates to a tie board, and a roof made of the mine and thatched roof.

[0002]

2. Description of the Related Art Conventionally, buildings of shrines and temples have been manufactured based on traditional shapes from ancient times, and many roofs and the like have a shape in which complicated curved surfaces are combined. And it is difficult for a skilled worker to carefully install a roof plate such as a copper plate on such a roof surface because of problems in appearance and difficult work such as removing and allocating the plate during the installation. It was a task that could not be carried out. FIG. 16 is a side view of such a roof, showing the completed construction. However, since the central part of the roof is almost flat, a normal single-character thatched roof has been installed, and the single-character thatched roof. The material A is divided from the central portion in the left-right direction and successively constructed.

By the way, near the gable side F of the side end of the roof,
The end of the ordinary one-character roofing plate is set as a base line G, and the roofing plate having a concentric curve is centered around the apex portion H of the roof in the flow direction of the roof slope. This part is usually called Minoko, and when you go to such a place with the ordinary single-letter roofing board A, you can bend the flat roofing board into a curved shape according to the building shape. It will be raised, and as the roofing work is continued, it will gradually lower to the eaves side from the beginning of the curved surface toward the wife side. Therefore, in such a place, the roof plate must also be roofed along the curved surface, and therefore, the shape is suitable for the curved surface shape of the instep part, and the one-letter roofing material in the center part and the curved surface part feel uncomfortable. There is a need for a roofing material with a special shape that is naturally continuous and does not descend downward. In other words, it is necessary that the end part of the gable side in which such curved surfaces are combined intricately is not a normal single-letter roofing board but a roofing board shape that conforms to the curved surface. In addition, if the boundary between the single-letter roofing material and the pearl roof part in this central part is unnaturally continuous, problems such as rain will occur and the appearance after construction will be unsightly. Was also needed.

Conventionally, when constructing such a minnow part,
For example, in order to make a full-scale shaped plate, the top part H with the boundary between the flat part and the curved part on the roof side of the roof as the base line G is set as the center, and a concentric circular arc is drawn around that point to make a layout. To obtain the curvature of the allocating line or measure the curved surface, and then take the material according to the shape plate, to manufacture a shinko roof plate with a different curvature and curved surface one by one. It was done. It takes skill and time to manufacture the curved shape of the roof plate while matching the curvatures of the upper and lower sides of the roof plate.
In addition, it is actually difficult to complete the rain lining work, and such roofing of the pits requires a great deal of labor and time.

In addition to the above, considering the continuity with the one-character roofing boards as described above, the one-character roofing boards near the center are separated by half the width of the horizontal roofing boards so that vertical vertical ridges do not overlap. Since the construction is carried out by shifting, there is also a problem that in a place related to a curved surface, a roof plate that extends over both the horizontal portion and the curved portion is required at a step interval in the roof flow direction. The roof board used in such a place is a member that requires a mortar tie plate, and this mortar tie board, like the awning roof board, requires skill in manufacturing and construction work.

[0006]

As described above, in the construction of the conventional pit roof, it is necessary to dimension each pit roof plate that is suitable for the curved shape of the roof and to bend the curved roof plate in accordance with the curved shape. It is necessary to manufacture a thing with a shape, such work requires many years of skill and labor, and at the time of installation, one by one, all the roof plates with different shapes must be correctly installed at a fixed position. However, this has a problem that it takes a lot of labor and time. In addition, work such as dimensioning is performed especially at a high place on the roof of a shrine and temple where the slope is steep, and there is a problem in terms of safety as well, which makes accurate dimensioning difficult and increases the accuracy of dimensioning. There is a problem that if it lacks, it will affect the rain finish and the appearance after construction.

The present invention has been made for the purpose of solving the above-mentioned problems in the prior art. Therefore, an object of the present invention is to provide a pit roof panel capable of performing construction work quickly and easily on a pit roof having a complicated curved surface. Another object of the present invention is to provide a mortar tie plate used for constructing the mortar roof plate. Still another object of the present invention is to provide a Minoko roof that is constructed using the above-mentioned roof plate.

[0008]

Means for Solving the Problems The inventors of the present invention have made extensive studies to solve the above problems, and as a result, have produced a mortar roof plate and a mortar joint plate having a predetermined curvature and curved shape in advance. Then, it was found that the above problems in the conventional technique can be solved by constructing a minnow roof using them, and the present invention has been completed.

Referring to FIG. 1 which is an embodiment of the present invention, and FIG. 2 which is a development view thereof, the mortar roof plate of the present invention has the four corners of a fan-shaped metal thin plate 1 in the pit roof plate of the present invention. The right engaging piece 11 and the left engaging piece 12 on both side edges are notched in a triangular shape and are bent with a gap provided on the upper surface side or the lower surface side to form the right and left engaging portions, and The upper engaging piece 13 is bent to the upper surface side with a gap to form an upper engaging portion, and the lower engaging piece 14 of the lower edge is bent to the lower surface side with a gap to form the lower engaging portion. It is characterized in that the curved surface is formed from the central portion of the thin metal plate toward both ends. In addition, the mortar tie plate of the present invention, the one side end direction from the central portion is a quadrangular shape, the other side end direction is a fan-shaped thin metal plate is notched in four corners in a triangular shape, engaging pieces of both side edge. To form the right and left engaging portions by forming a gap on the upper surface side or the lower surface side respectively, and bending the upper engaging piece on the upper end edge to the upper surface side by forming a gap to form the upper engaging portion. Formed, the lower engaging piece at the lower edge is provided with a gap and bent to the lower surface side to form the lower engaging portion,
A curved surface is formed on the fan-shaped portion of the thin metal plate. Minoo roof of the present invention, using a plurality of types of different curvature of the above-mentioned roof plate, a small curvature roof plate is arranged upward, a large curvature roof plate is arranged below It is characterized by being done. In that case, using a plurality of types of different curvature of the above-mentioned koukou tie plate, arranged every other step in the flow direction of the roof slope, the koukou tie plate is engaged in combination with the kou roof plate in order. do it.

In the present invention, a copper plate is preferably used as the thin metal plate used for the roof and the roof tie board. Further, the shape thereof is a fan shape, but the right and left engaging pieces at both end edges are bent in close contact at the upper and lower ends, and an engaging portion having a gap is formed in the central portion.

[0011]

The present invention has the above-mentioned structure for the mortar roof plate and the mortar tie plate, so that the upper and lower portions of the engaging pieces on the side portions between the adjacent mortar roof plate or mortar tie plate. It is possible to change the engagement depth of the mat, and therefore, even if the curvature of the part of the pit does not correspond to the curved surface of the pit roof, the angle and depth of the engagement can be adjusted. Will be able to respond. In other words, if the engaging ranges of the right and left engaging portions formed on the side edges of the pit roof are adjusted and appropriately adjusted, it can be widely applied to roofs bent into various shapes, and the rain pattern is also perfect. The appearance after construction is also very good. Therefore, a plurality of types having a predetermined curvature and curved shape in advance, for example, two types or three types
It is only necessary to form a kind of Mino roof shingles and Mino shingles tie plates, and if necessary, select and construct one with a suitable curvature shape, thereby making it possible to bend most of the roof regardless of size. You will be able to adapt to the minnow part.

For example, R1300mm, R3000m
m, R 4000 mm, etc. 2 or 3 types of mortar roof plates with curvatures are prepared in advance, and a wide range of lengths and curvatures can be obtained by combining mortar roof plates and mortar joint plates with different curvatures. It can be easily installed by adapting to a curved curved roof. Further, when a single-character roofing board is continuously constructed on a curved surface, it is possible to more completely construct the construction by using a sewage joining board which is flat on one side with the base line G as a boundary as described above. In addition, since the four-cornered roof plate having a fan shape is notched at the four corners and bent to form the engaging piece, both ends of the engaging piece are notched. And as a result,
The engaging work can be performed smoothly, and the work can be performed safely without damaging other roof boards at the tip.

[0013]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 2 is a plan view showing the developed Mino roof plate of the present invention in FIG. In the figure, the broken lines along the four edges of the fan-shaped thin metal plate 1 represent folding lines, and the four corners have triangular notches 15, which are outside the intersection of the folding lines. It is formed by cutting one side at an angle. As the fan-shaped thin metal plate, for example, a copper plate having a thickness of about 0.4 mm is preferably used. The triangular notch is preferably formed by cutting the fold line at a position crossing two lines.
The notch 15 has a shape in which the end of the bent engaging piece shown below is cut in, which facilitates the engaging work and allows the degree of freedom of the engaging portion as described later. Fine adjustment is possible after the engagement. next,
The right engaging piece 11 at the right end edge is bent by a fold line with a gap on the lower surface side of the main body to form a right engaging portion, and the left engaging piece 12 at the left end edge is formed by a fold line in the upper surface of the main body. The left engaging portion is formed by bending with a gap provided on the side. FIG. 3 is a plan view showing this state. It is necessary to make the gap between the engaging portions larger than the thickness of the metal thin plate, but when using a copper plate having a thickness of 0.4 mm, about 1.5 mm to 2 mm is good for work.

Next, the upper engaging piece 13 of the upper edge is bent and raised toward the upper surface side with a gap provided between the upper engaging piece 13 and the lower engaging piece 1 of the lower edge.
It is preferable that 4 is bent to the lower surface side with a gap provided so as to hang down, and the rising and hanging engagement pieces 13 and 14 are subjected to wavy knurling over substantially the entire length. FIG. 4 is a perspective view showing this state, and FIG. 5 is a partially enlarged view thereof. In this knurling process, the engaging piece is bent along a curved bending line.
The material is left on the upper side, and the lower engaging piece is stretched on the lower side. Also, by knurling,
It becomes possible to change and adjust the curvature of the curved surface portion of the roof plate, and it becomes easy to adapt the construction to the curved surface portion of the roof base of the building. The length and depth of the knurling may be appropriately determined, and in the case of this embodiment, a length of 12 mm and a depth of about 1 mm were adopted.

The knurled upper and lower engaging pieces are further bent to form the upper and lower engaging portions. In the case of the upper engaging piece, the left side of the upper edge has a slightly large curvature. It is preferable that the lower engaging piece 14 is bent so that the right side has a slightly smaller curvature on the right side and the lower engaging piece 14 has a slightly larger curvature on the right side and a slightly smaller curvature on the left side. It is preferable to bend the lower surface side with a curvature. The reason is that, when the upper and lower engaging pieces are bent with the right and left curvatures changed as described above, the engagement can be smoothly performed when the roof plates are fitted and engaged with each other. At this time, in each of the right-side and left-side engaging portions, the upper and lower ends of the right and left engaging pieces are crushed to be in a tight contact state with no gap, and the upper engaging portion 13a and the lower engaging portion 13a, respectively. The engaging portion 14a is formed. FIG. 6 is a view for explaining this state, and is a cross-sectional view taken along the line B1-B1 of FIG. As shown in FIG. 1, the thin metal plate having the engaging portions formed as described above is curved so as to form curved surfaces from the central portion toward both ends, as shown in FIG. A plate is formed. FIG. 7 is a view for explaining that state, and is a sectional view taken along line B2-B2 of FIG. As shown in FIG. 7, the horizontal cross section of the pit roof panel of the present invention is curved in an arc shape.

In the mortar roof plate of the present invention, the corners E (see FIG. 1) of the upper engaging piece 13 and the lower engaging piece 14 around the thin metal plate are triangularly cut at their tips by the notches 15. Because of this, the engaging work can be carried out smoothly without being caught and the work can be done safely. Further, as will be described later, since the degree of freedom of the engaging portion can be provided, fine adjustment can be made after the engagement.

8 and 9 show another embodiment of the pit roof panel of the present invention. FIG. 8 is a developed view and FIG. 9 is a perspective view. This embodiment shows an example in which the right and left engaging pieces on both end edges are gradually widened toward the center from the upper and lower ends. In the drawing, the width of the side engaging pieces 11 and 12 of the fan-shaped thin metal plate 1 is widened in an arcuate shape at the central portion so that the adjustment at the time of engaging can be performed more effectively.
In the case of this instep roof plate, when engaged, it becomes possible to engage by inclining the wide part of the central part at the apex.
It becomes easy to change the state when engaged.

Next, the pearl tie connecting plate of the present invention will be described. FIG. 10 is a development view of the Minoko connecting plate. The Mino Kou tie board is used to connect the above-mentioned Mino roofing material and the one-character roofing plate, and one side end direction is a quadrangular shape from the central part, and the other side end direction is a fan shape. Metal sheet 2
Is used. The four corners of this thin metal plate are notched in a triangular shape to form notches 25. The right and left engaging pieces 21 and 22 at both end edges are bent with a gap provided on the upper surface side or the lower surface side to form the right and left engaging portions. (See FIG. 11) Next, the upper engaging piece 23 of the upper edge is bent and raised to the upper surface side with a gap provided between the upper engaging piece 23 and the lower engaging piece 2 of the lower edge.
Bend 4 by making a gap and bending it to the lower surface side. It is preferable that the wavy knurling is applied to almost the entire length of each of the raised and hung parts of the engaging piece having a curvature (see FIG. 12). Next, the upper and lower engaging pieces are further bent to form the upper and lower engaging portions. At this time, in each of the right-side and left-side engaging portions, the upper and lower ends of the right and left engaging pieces are crushed to be in a close contact state with no gaps, and the upper engaging portion 23a and the lower engaging portion 23a, respectively. The engaging portion 24a is formed (see FIG. 14). In this example, the gap of the upper engaging portion is wide at the right end (for example, about 4 mm), and the gap at the left end is narrow (for example, 2 m).
m)). This is for facilitating the fitting of the roof plates. On the contrary, the gap of the lower engaging portion is wider at the left end portion than at the right end portion.

The thin metal plate having the engaging portions formed as described above is curved so that a curved surface is formed in its fan-shaped portion. FIG. 13 is a perspective view of a mortar board connecting plate of the present invention manufactured as described above. The left half has a flat rectangular shape to be continuous with the one-letter roofing plate, and the right side has a curvature and is curved. It is also curved downward.
The cross section in the horizontal direction is curved in an arc shape from the central portion toward one side. FIG. 15 shows the state and is a sectional view taken along the line D2-D2 of FIG. In addition, you may form a pearl tie board in a relationship contrary to the above. That is, the right half is formed into a flat prismatic shape so as to be continuous with the one-letter roof panel, and is curved downward with a curvature on the left side.

Next, a case will be described in which the above-mentioned roof and roof board of the present invention and the roof and tie board are used for construction on the roof and the roof of the roof is constructed. FIG. 17 shows a side view of a MINKO roof of the present invention constructed using the above MINKO roof plate. The usual single-letter roofing material A is applied near the center of the roof, but the roof shape near the gable F has a curved shape that swells inward of the building, and this part is usually called Minoko. This is what is called. The Mino roof plate and the Mino tie board of the present invention are applied to this Mino roof. That is, the mortar roof plate B of the present invention is applied to the mortar portion, but the size of the mortar roof plate B is almost the same as the one-letter roofing material A, and particularly the length in the flow direction of the roof is used. Those having the same size are preferable. This Mino roof plate B is continuously constructed in the horizontal direction. Since the upper and lower edges of the Mino roof plate B are formed so as to substantially match with the roof, the side portions have a V shape toward the center of curvature and the whole is substantially fan-shaped.

When arranging the mortar roof plate B of the present invention, the mortar roof plates B are engaged with each other at the pit part,
In that case, a relatively small curvature of the roof of the instep (FIG. 18 (a)) is used for the relatively upper part of the roof of the instep, and construction is performed for several steps. For example, the curvature of the upper edge is about R1300mm
The minuko shingles that were molded into 1300m from the top of the roof
Install at a distance of about m. At that time, the curvature does not match at the front and rear distances, but in that case, the engagement state of the side engaging pieces may be adjusted to make it suitable as described later. Next, a few steps of construction are performed so that the Mino roof material (FIG. 18 (b)) having a larger curvature than that described above is arranged under the lower part. For example, if the curvature is molded to R3000mm,
Install using the same method. If the roof is larger, it may be constructed by using a pit roof plate (for example, R4000 mm) having a larger curvature, if necessary. As described above, the minnow roofing material of the present invention has a structure in which the engaging portion formed by the engaging pieces on the side portions is adjustable,
If you prepare two or three types of mortar roof panels with different curvatures, you can adapt to any roof.

In the boundary area between the roof part and the flat part of the roof, the roof plate of the present invention is directly connected to the single roofing plate A, or the roof plate D referred to as "kasuga" or the roof panel of the present invention. It is constructed by connecting with the instep connecting board C.

19 to 21 are views for explaining the structure of the glazing D. FIG. 19 is a perspective view of the glazing, FIG. 20 is a developed view, and FIG. 21 is a plan view. The engaging pieces 31 to 34 at the peripheral edge of the substantially quadrilateral metal thin plate 3 provided with the elongated triangular notches 35 at the four corners are bent to provide the engaging portions, but the right end of the metal thin plate 3 is the lower surface side. Is bent to form a right engaging portion, and the left end is bent to a lower surface side to form a left engaging portion. Next, while maintaining the gap between the engaging pieces on the side portions, the engaging pieces 33 on the upper edge are provided with a gap to bend to the upper surface side to form the upper engaging portion, and the engaging pieces 34 on the lower edge are formed. To form a lower engaging portion by bending the lower surface side with a gap. The width of each of the engaging pieces is preferably about 15 mm, but even if it is about 20 mm, a sufficient effect can be obtained, so that the engaging piece may be designed to have an appropriate width. At this time, the gap of the upper engagement piece 33 is widened from the right direction to the left direction in the illustrated example, because this is to fit and engage the side portion of another roof plate in this gap. On the contrary, the joint piece 34 widens from the left direction to the right direction, which is a natural shape for engagement.

As described above, the Mino roof plate B is constructed by combining it with the scintillator D and the Mino shell tie plate C. In the gap of the right engaging portion bent to the lower surface side with a gap provided. Then, insert the left engaging piece of the Minoko roof plate B to be constructed next and construct horizontally. In the case of using the mincoin tie plate, it may be arranged every other stage in the flow direction of the roof slope, and combined with the mincoin roof plate to sequentially engage with the construction. In addition, the braces D may be arranged and installed every other stage.

In construction, the depth of the engaging portion is changed when the curvature needs to be adjusted. 22 and 23 are diagrams for explaining the case. The mortar roof plate of the present invention has the engaging portion having the above-mentioned structure, and therefore, the left-hand engagement of the right-hand mortar roof plate to be inserted into the right-hand engaging portion 11a of the left-hand pit roof plate. It is possible to freely change and adjust the depths of the upper part and the lower part of the piece 12 within a certain range.
Therefore, in FIGS. 22 and 23, when the width of the upper engaging portion is wide W1, the width of the lower engaging portion is narrow W3, and conversely when the upper engaging portion is narrow W2, the lower portion is wide W4. It can be installed by changing the curvature to suit the roof.

It should be noted that although the horizontal engagement of the roof has been described so far, in the vertical direction, which is the flow direction of the roof,
It suffices to engage the upper engaging piece 13 of the roof plate located at the lower part and the lower engaging piece 14 of the roof plate located at the upper part for construction. Although not shown when constructing, it is the same as a normal single-letter roof that is appropriately fixed to the roof plate of the roof with a suspender. Further, in the present embodiment, the roofing material of the right-handed roof is shown, but in the case of the left-handed roof, its shape may be symmetrical.

[0027]

As described in detail above, the pit roof panel of the present invention has various shapes if the engaging ranges of the right and left engaging portions formed on the side ends thereof are appropriately shifted and adjusted. It can be widely applied to curved roofs, has a perfect rain finish, and has an extremely good appearance after construction. In addition, by preparing a plurality of types of roofs having different curvatures, for example, two types or three types, the mortar roof plate of the present invention can be applied to almost any roof having a complicated curved surface. That is, the upper and lower edges of the pit roof panel of the present invention have a gentle curve, but for a roof of which the roof has an upper part, for example, R1300 mm, and a roof of which the lower part has a roof Is R3000 mm, and in some cases even R4000 mm or the like having a curvature can be prepared so that it can be used for almost any roof-shaped curved surface by preparing only two or three types. become. Therefore, according to the present invention, there is no need for complicated and difficult dimensioning and board cutting as in the prior art,
Work can be performed safely and quickly. Also,
Since the corners are notched in a triangular shape, the tip of the engagement piece is cut into an obtuse angle when bent, so that the engagement work can be prevented. There is also an effect that it can be installed without getting caught during work, and that it does not damage other roofing boards at the tip, and that work safety can be achieved. And, the Minoko-roof roof that is roofed using the Minou-ko tie board of the present invention has an extremely good appearance after construction because the horizontal lines of the roof are smoothly continuous, and the rain-finish Moreover, it is not easy to expect with a traditional hand-made pearl tie board because of its excellent workability.
