Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arched roof having a curved roof surface, and therefore has a long curved arched shape which is excellent in design effect without wrinkles in the roof plate body. The present invention relates to a hanger for fixing a roof shingles to a roof substrate, which can easily fix the arch-shaped roof shing to the roof substrate without rattling.

[0002]

2. Description of the Related Art Conventional building roofs are generally shaped like a combination of flat surfaces, but if a part or the whole of the roof surface is curved, it has an arched shape that enhances the design effect. The requirement for such curved roofs has increased in recent years as it is possible to roof an arched roof.

As the roof plate constituting the roof surface, various ones such as a long plate and a fixed plate formed by bending a metal plate have been manufactured. The roof plate for roofing the arched roof as described above. Since it is difficult to properly connect the rain ends of the ends in the longitudinal direction to each other, the engaging parts are usually formed only on both side edges in the width direction, and the connecting parts are connected to the ends in the longitudinal direction. A long one is used which is curved in the longitudinal direction in the state of not having.

An example of a conventional long roof plate for roofing such an arched roof will be briefly described. As a conventional long roof plate 1a 'for thatching an arch-shaped roof, for example, as shown in Fig. 5, a roof plate main body 1aa' is made up of a rising portion that is upright over the entire length on both side edges. Joint part 1a
A roof plate 1a 'having a flat groove-shaped cross section in which b'is formed and curved in the longitudinal direction with a predetermined radius of curvature can be mentioned.

In order to use that kind of roof plate 1a 'to roof an arched roof, the engaging portions 1ab' of the roof plates 1a 'which are fixed adjacent to each other on the roof base material 6 are predetermined. With the gaps, the suspensions 1b 'are arranged in the gaps and fixed to the roof base material 6, and the engaging portions 1ab' are connected via the suspensions 1b 'as shown in FIG. This connecting portion was hidden by the cap 1c '. That is, the engaging portions 1ab 'of the roof plate 1a' fixed adjacent to the rising portions 1ba 'on both sides of the substantially U-shaped suspension 1b' are butted, and the mated roof plates 1a 'are engaged. Rising part of section 1ab 'and suspension 1b'
Groove-shaped cap body 1 of cap 1c 'on the upper end with 1ba'
A substantially U-shaped fastening portion 1cb 'formed on the side end of ca'
After covering it with a lid, attach the lock portion 1cb 'to the engaging portion 1a of the roof plate 1a'.
The work of bending 180 degrees together with the rising part 1ba 'of the b'and the suspender 1b' and tightening it was performed over the entire length.

Since the roof plate 1a 'is for roofing an arch-shaped roof, it is formed in a shape curved in the longitudinal direction. To manufacture such a roof plate 1a', Both side edges of the flat metal strip are bent upward to engage with both side edges of the roof plate main body 1aa '.
After forming the part to be 1ab ', it was curved in the longitudinal direction.

However, after the portions which become the engaging portions 1ab 'are bent upward at both side edges of the portion which becomes the roof plate main body 1aa', the roof plate 1a 'can be formed by curving in the longitudinal direction. Then, since there is a large difference in elongation due to bending between the upper end edge and the base end portion of the portion that becomes the engaging portion 1ab ′ when bent, an unreasonable force acts on the base end portion of the engaging portion 1ab ′. As a result, wrinkles occur in the roof plate main body 1aa 'and the engaging portion 1ab' near the base end as shown in FIG. 5, and the design effect is significantly impaired.

Further, in order to roof the roof with the above-mentioned roof plate 1a ', the long cap 1 is a member different from the roof plate 1a'.
c'is used, but when manufacturing this cap 1c ', the engaging portion of the roof plate 1a' that is adjacent via the suspension 1b '
The cap 1c 'must be curved in the longitudinal direction with a predetermined radius of curvature corresponding to the roof plate 1a' while maintaining a constant space between the two fastening portions 1cb 'corresponding to the position of 1ab'. Since the cap body 1ca 'is groove-shaped and a substantially U-shaped fastening portion 1cb' is formed on both side edges thereof, the cap body 1ca 'and the fastening portion 1cb when curved in the longitudinal direction. It is difficult to manufacture in a size corresponding to the size of the roof plate 1a ', since there is a portion that is bent upward or downward in each of the' and the difference in elongation due to the bending in these portions becomes large. In addition, in order to fasten the curved fastening portion 1cb 'of the curved cap 1c' over the entire length, bend the long curved curved fastening portion 1cb 'so that it is also bent downward so that it is located below. Since it has to be fastened, Not only is bad change in work efficiency, excessive force to 馳締 Me part 1cb 'distortion there has been a drawback that impair the design effect occurs occurs.

In addition, the above-described fastening work is of course carried out over the entire length of the roofing plate after arranging the roofing plate on the roof surface of the building, and moreover, it is only necessary to carry out the fastening work once. If the water leakage and wind pressure resistance are not sufficient, it is necessary to repeat the tightening process further, which requires time and labor, and the work efficiency is poor, and a special device is required for the tightening process. .

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art, and has a long curved arch-shaped roof roof plate curved in the longitudinal direction which is excellent in design effect without wrinkles on the roof plate body. It is an object of the present invention to provide a hanger for fixing a roof to a roof base material, which can easily fix an arch-shaped roofing board to the roof base material without rattling.

[0011]

As a result of various studies to solve the above problems, the inventor of the present invention has found that a roof plate for roofing an arch-shaped roof is formed in a shape curved in the longitudinal direction and the roof. Since the engaging pieces for connecting the roof plates fixed adjacent to both side edges of the plate body are formed over the entire length of both side edges, when the roof plates are curved in the longitudinal direction, In order to prevent wrinkles from occurring on the roof plate body and the engaging pieces without exerting an excessive force on the roof plate body, the engaging piece should not be a flat rising part, but the roof plate body. Focusing on the fact that wrinkles can be prevented from occurring in the roof plate main body by providing a ridge portion at a height position close to the ridge and absorbing the strain in the ridge portion, Separated from the roof plate to hide the connection part when connecting Not only is the cap easy to fabricate, the cap must be curved in the longitudinal direction with a radius of curvature that approximately matches the radius of curvature that is curved in the longitudinal direction of the roof plate. Since the height corresponding to the height of the piece is required and the width is narrow, the accuracy in the width direction is poor and not only the design effect of the roof surface constructed is impaired but also the cap is engaged with the engaging piece of the roof plate. We paid attention to the fact that rattling tends to occur when it is played.

[0012] As a result of various studies, an arch-shaped roof plate for roofing a curved arch-shaped roof is shown below as engaging pieces formed over the entire length of both side edges of the roof plate body. The first engaging piece with which the second engaging piece of the roof plate to be fixed is engaged with the outer surface of the roof plate main body-side ridge has a convex shape at the height position close to the roof plate main body. Is formed, and a substantially inverted U-shaped portion is formed which is bent upward from the main body side convex portion and then bent to the back surface side to form a substantially inverted U-shaped portion. An edge-side convex ridge is formed on the opposite side of the roof plate main body from the letter-shaped portion, and the second engaging piece is provided at a height position close to the roof plate main body on the center side of the roof plate main body. A main body side convex streak forming a convex portion is formed, and a substantially inverted U-shape that is bent upward from the main body side convex streak and then bent to the back side is formed. Be substantially inverted U-shaped portion is formed,
Further, for a long arch-shaped roof that is curved in the longitudinal direction as long as it has a shape in which an edge-side convex strip that forms a convex on the side opposite to the roof plate body is formed from the substantially inverted U-shaped portion It was first clarified that the roof plate will be highly accurate and excellent in design effect without wrinkles.

As a result of further research based on the above-mentioned investigation results, a short suspension for fixing the arch-shaped roof roof plate to the roof base material is fixed to the roof plate at one end first. A mountain-shaped piece which forms a locking portion on the back surface of the main body side ridge portion of the first engaging piece and the other end of which is brought into contact with the back surface of the edge side ridge portion of the first engaging piece, respectively.

And a fixing portion 3d of the first engagement piece 3 are formed together to form a space.

A roof plate 1 has one end fixed first.
Of the first engaging piece 3 on the rear surface of the main body side convex strip 3a and the other end of the first engaging piece 3 on the rear surface of the edge side convex strip 3c. The chevron piece 5a to be formed and approximately 180 degrees from the locking part 5aa of one of the chevron pieces 5a to the back side.
After being folded back, the rising portion 5b is bent downward from the vicinity of the top of the chevron piece 5a, and the lower end of the rising portion 5b hits the edge-side ridge 3c of the first engaging piece 3 of the roof plate 1. The suspension according to the present invention has a fixed portion 5c that is bent at a right angle to the side of the engaging portion 5aa that is brought into contact with and is fixed to the roof base material 6.

Arch-shaped roof shingles 1 fixed to a roof base material 6 by the hanging members 5 according to the present invention having the above-described shape.
The first engaging piece 3 and the second engaging piece 4 and the roof plate main body 2 are integrally formed of the same member and have a planar shape which is perpendicular to the roof plate main body 2 in a cross section thereof. Since the portions do not exist in the first engagement piece 3 and the second engagement piece 4, when the roof board 1 is curved in the longitudinal direction, it is formed in the first engagement piece 3 and the second engagement piece 4. Protruding ridges 3a, 3c and

It is possible to effectively prevent the generation of wrinkles due to an unreasonable force acting on the main body 2 due to the difference in elongation caused by deformation, which has a high design effect.

Since the suspension 5 according to the present invention for fixing the arch-shaped roofing roof plate 1 to the roof base material 6 has a short length, the portion of the roofing plate 1 that contacts the suspension bar 5 is short.
Although the roof plate 1 is curved in the longitudinal direction, the suspension 5
Is linear and can be engaged with the first engaging piece 3 in the longitudinal direction of the roof plate 1.

Therefore, in order to manufacture the suspension 5, for example, a roll forming method for continuously forming a member having a predetermined cross-sectional shape from a metal strip that has been generally used in the past has been used to form the predetermined cross-section. It can be manufactured accurately and easily by forming it into a shape and then cutting it into an appropriate length.

In order to fix the arch type roof shingles 1 to the roof base material 6 with the suspensions 5 according to the present invention, the first engaging piece 3 of the shingles 1 to be fixed first is provided with a roof such as wind pressure. Considering the load acting on the plate 1, the engaging portions 5aa at both ends of the chevron-shaped piece 5a of the suspension 5 are spaced apart from each other at a predetermined interval in the longitudinal direction, and the ends of the first-side engaging piece 3 and the main body side ridge portion 3a. As shown in FIG. 1 and FIG. 4, the suspension 5 is fitted inside by contacting it with the back surface of the edge-side convex strip 3c.
Fixing parts 5c of the roof with nails, screws, tapping screws, etc.
Then, the roof plate 1 which is fixed to the roof base material 6 is fixed to the roof base material 6. When the fixing portion 3d is extended further to the edge side of the edge-side convex strip 3c of the first engaging piece 3, the nails, screws, tapping screws, etc. are fixed as shown in FIG. 3d and the fixed portion 5c of the suspension 5 are penetrated and driven.

Next, the second engaging piece 4 of the roof plate 1 to be fixed next is pressed against the first engaging piece 3 of the roof plate 1 previously fixed from above so that the second engaging piece 4 The back surfaces of the main body side ridge 4a and the edge side ridge 4c contact the outer surfaces of the edge side ridge 3c and the body side ridge 3a of the first engagement piece 3, respectively,
The first engaging piece 3 is engaged by the spring action of the second engaging piece 4. At this time, the substantially inverted U-shaped portion 3b of the first engaging piece 3 of the roof plate 1 fixed first and the substantially inverted U-shaped portion 4b of the second engaging piece 4 of the roof plate 1 fixed next. Since it is preferable that a space and a space are formed between them and in order to prevent infiltration of rainwater and the like due to the capillary phenomenon in the engaged state, the above-mentioned substantially inverted U The character portions 3b and 4b may not come into contact with each other.

When the above work is sequentially repeated in the width direction of the roof plate 1 over the entire surface of the arched roof to be constructed,
The arched roof is thatched.

[0030]

As described above in detail, since the suspension according to the present invention is short, it is engaged with a minute portion which can be regarded as a straight line of the roof plate, so that it is sufficient if it has a linear shape. It can be manufactured.

Further, the arch type roof shingles fixed by the suspenders according to the present invention can be curved in the longitudinal direction without causing wrinkles in the shingles main body exposed on the roof surface, so that the design effect is obtained. A cap with poor dimensional accuracy can be used for the first engaging piece and the second engaging piece in the process of connecting the roof boards in the width direction, which allows the arched roof with a high appearance to be roofed Since the roof plate can be roofed without doing so, an arched roof with a high design effect can be roofed.

Then, the first engaging piece and the second engaging piece formed on both side edges of the arch type roofing roof plate both have a similar shape in which ridges are formed. In addition, since the first engagement piece and the second engagement piece are curved at the same time when arched, the relative dimensional error between the first engagement piece and the second engagement piece is small. Therefore, when the first engaging piece of the roof plate that has been fixed first is engaged with the second engaging piece of the roof plate that is fixed next, it is firmly engaged, and the adjacent roof plates are rattled. It can be firmly connected in the absence.

Further, on the base end side where the second engaging piece of the roof plate main body is formed, the fixing portion of the suspension fixed to the roof base material (further end of the ridge portion on the edge side of the first engaging piece). When the fixing portion is extended to the edge side, a step portion is formed to form a space for accommodating the fixing portion of the hanger and the fixing portion of the first engaging piece) with the roof base material. When a step portion having a shape corresponding to the step portion is formed on the base end side where the first engagement piece of the roof plate body is formed, by fixing the fixing portion of the suspension to the roof base material, There is no deformation on the base end side of the roof plate main body on which the other engaging piece is formed, and the parts of the roof board main body on both sides of the roof plate main body have the same shape in a state in which the two engaging pieces are engaged. The design effect will be more excellent.

In order to fix the roof plate having various effects such as the design effect, the roof-side fixed ridges and the main-body-side ridges of the first engaging piece of the roof plate to be fixed first are engaged. After fixing the hanger according to the present invention in which the stopper is brought into contact and fitted in the first engaging piece to the roof base material, it is next fixed to the outer surface of the first engaging piece of the roof plate. Since the second engaging piece of the roof plate is pressed and engaged to connect, the suspender can be easily fixed to the roof base material, and a cap for hiding the connected portion is not required, and the connecting and fixing work can be performed. It's easy and very efficient.

As described above, in the hangings according to the present invention, one end of the first engaging piece of the roof plate, which is fixed first, is on the back surface of the main body side ridge and the other end is the first engaging piece. Since the mountain-shaped pieces that form the two locking portions are respectively brought into contact with the back surfaces of the convex strips on the edge side of the engagement piece, the first engagement piece of the arch-shaped roof roof plate has no rattling. Can be fitted inside,
In addition to the effect that the adjacent roof plates can be firmly connected to each other in a rattling-free state as described above, the roof plate can be easily and reliably fixed to the roof base material in a rattling-free state.

The suspension according to the present invention having various effects as described above has a great industrial value.
