Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertically-roofed roof structure using a vertically-roofed roofing plate made of a metal steel plate in the direction of eaves.

[0002]

2. Description of the Related Art As a conventional thatched roof structure of this type,
The one shown in FIG. 6 is known. In the drawing, 1 is a roof substrate, 2 is a gutter member arranged along the flow direction on the roof substrate 1, and 3 is a roof substrate 1 so as to straddle the gutter member 2.
Suspensions 4 arranged on the roof, 4 are roof plates fixed by the suspensions 3, 5 are cover members fitted to the joints between the adjacent roof plates 4 and 4, 6 is a roof substrate 1 and a roof An inner layer material having a heat insulating or soundproofing function and the like interposed between the board 4 and a foamed polyethylene 7 attached to the back surface of the roof board 4 is shown.

The roof plate 4 is made of a thin metal plate material as a roof plate for a vertical lengthwise roof in the direction of the eaves, and the side edge portions (both ends in the purlin direction) of the cover member 5 are provided. Is formed with a stepped portion 4a for accommodating the upper surface of the stepped portion 4b to be flush with the roof surface, and the lower end of the side edge 4b hanging from the end of the stepped portion 4a is folded back inward. Joint part 4c
Are formed.

On the other hand, diagonally downward engaging claw portions 3a which engage with the roof plate engaging portion 4c are formed opposite to each other in the central portion of the upper surface of the suspension 3, and the pair of engaging claw portions are formed. 3a, 3a
The engaging ends 4c, 4 of the roof panels 4, 4 adjacent to the
After engaging c with each other, the leg portion 5a of the cover member 5 is inserted between the side edge portions 4b and 4b, and the left and right protrusions 5b and 5b are connected to the lower ends of the engaging end portions 4c and 4c. The roof boards 4 and 4 are fixed to the roof substrate 1 via the suspenders 3 arranged so as to be located between them.

[0005]

By the way, according to such a conventional thatched roof structure, the suspension 3, the roof plate 4, and the cover member 5 are engaged with each other by spring back (elastic force). However, if there is an error in the mounting interval between the adjacent hangings 3 or an error in molding the roof plate 4, the interval at which the roof plate 4 should be engaged deviates from the regular size. There is a problem that it becomes difficult to fit them or they cannot be engaged significantly.

Concretely, for example, when the mounting interval of the suspensions 3 is larger than the width of the roof plate 4, the width of the roof plate 4 becomes relatively insufficient, and therefore the engaging end portion 4c thereof. Cannot be engaged with the engaging claw portion 3a of the hanger 3.
On the contrary, when the attachment interval of the suspension 3 is smaller than the width of the roof plate 4, the width of the roof plate 4 is relatively excessive, and therefore the engagement end 4c and the suspension 3 are engaged with each other. If the cover member 5 cannot be brought into a sufficiently engaged state with the mating claw portion 3a and the cover member 5 is forcibly mounted as it is, the flatness of the roof plate 4 is affected by the excess width, which is not preferable in terms of design.

The problem caused by such an error is also the same for the cover member 5, that is, the cover member 5 fitted between the side edge portions 4b, 4b of the roof plates 4, 4 adjacent in the girder direction. Cannot reliably engage unless the distance between the side edge portions 4b, 4b is maintained at a specified value, and particularly when the roof plate 4 is not properly engaged with the hanger 3, the cover member is formed. The mounting state of No. 5 becomes more unstable.

On the other hand, a member such as the roof plate member 4 and the cover member 5 formed by bending and forming a thin metal plate member is apt to be twisted at the time of molding. I am trying to correct it depending on. Therefore, if there is an error in the mounting interval of the suspension 3 or the dimension of the roof plate 4 as described above and a reliable engagement state cannot be provided, such a twist cannot be corrected sufficiently.
In addition, even if a margin is provided in the engaged state in order to absorb the error, the engagement relationship will be loosened accordingly, and the twist cannot be sufficiently corrected.

The present invention has been made by paying attention to such a conventional problem, and the roof plate is surely placed on the roof substrate without being affected by the dimensional error of the roof plate and the error of the mounting interval of the suspension. An object of the present invention is to provide a vertically-roofed roof structure that can be fixed and that can reliably correct the twisting deformation of the roof plate and the cover member during manufacturing.

[0010]

In order to solve the above-mentioned problems, the present invention has a gutter member arranged along the direction of flow of a roof substrate and a suspension fixedly provided across the gutter member. In a vertically-roofed roof structure in which side edges of a vertically-roofed roof board are connected to a child, side edges of both sides of the roof board are bent downward to form a fold lower portion, and outwardly extend from a lower end of the fold lower portion. On the other hand, while forming the projecting portion, the hanging member is fixed to the lower member having a fixing flange portion to the roof underlay, and is fixed to the lower member from above, and the roof plate extending portion is pressed between the lower member and the lower member. And the upper part of the roof that is adjacent to the left and right sides , so that the extension parts of the vertical roofing roof panels adjacent to each other face each other.
While arranging the upper member on the lower member while securing a displacement allowance space around the folded lower portion of the vertical roofing roof plate, the folded lower portion is prevented from being interfered by other members both inside and outside thereof. The roof plate is fixed by being fixed.

According to this structure, the roof plate is held in such a manner that its extending portion is sandwiched between the lower member of the hanger and the pressing portion of the upper member, so that the roof plate is reliably and firmly stabilized. Can be held. Furthermore, inside and outside of the folded part are
Space that does not interfere, that is,
Due to the error and the error when molding the roof plate,
Displacement allowance space that allows the displacement of the roof plate
Is ensured. Therefore, the roof plate is securely fixed to the hanger regardless of the error of the roof plate dimension caused by the error of the bending angle and the bending position of the folding part and the error of the mounting interval of the hanger, and therefore, the roof plate is not twisted. Even if there is, this is surely corrected.

By the way, in the above structure, by forming a rising part upward from the outer end of the extending part of the roof plate, a groove-like gutter opened upward by the rising part, the extending part and the folded part. parts are formed, of being discharged rainwater came invaded been supplemented in this gutter member in the eaves direction between the roof plate and the retaining clips upper member, the gutter member is provided also on the lower side of the retaining clips In addition to this, it has a double drainage structure, and therefore has excellent rain scavenging performance.

Further, according to the present invention, the lower member of the suspension is provided with the engaging portion for engaging with the folded lower portion of the roof plate, and this engaging portion suppresses the floating of the roof plate, so that the upper member is fixed. The workability can be improved by preventing the roof plate from coming off and scattering due to strong winds.

Further, according to the present invention, the upper member of the suspension is
A cover member may be provided to cover the space between the joints of the adjacent roof plates from the upper surface. In this case, the cover member can be directly engaged with and fixed to the upper member without being affected by the mounting state of the roof plate, so that a mounting defect due to a dimensional error can be avoided and a strong mounting can be performed. Yes, and therefore also corrective of the twist.

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 11 is a base of the roof.
The base 11 is made of, for example, a base material such as a wooden blank board laid on a main material made of C-type steel (not shown) and a waterproof material such as asphalt roofing.

A flat portion 12 is formed on the base 11.
A long gutter member 12 having a substantially U-shaped cross-section, in which standing wall portions 12b are raised at both ends of a, is arranged along the flow direction of the base 11 and straddles the gutter member 12. A hanger 20 is provided that includes a lower member 21 that is disposed and an upper member 22 that is joined to the lower member 21 from above. The lower member 21 and the upper member 22 are each formed of an extrusion mold material such as an aluminum alloy or a hard resin.

22d is formed. Engagement portions 22e and 22e that engage with the cover member 26 are formed at both ends of the upper surface 22a of the upper member 22.

The cover member 26 has a flat surface portion 26a whose both ends overlap the upper surface of a roof plate stepped portion 24a which will be described later,
It is composed of a pair of engaging leg portions 26b formed downward from the vicinity of both ends thereof, and an engaging portion 26c is folded back inward at the lower end portion of the engaging leg portion 26b, and is engaged with the engaging portion 26c. The cover member 26 is fixed to the upper member 22 based on the engagement with the engaging portion 22 e .

Reference numeral 24 denotes a roof plate fixed by the suspension 20. The roof plate 24 has a folded lower portion 25a formed by bending a side edge portion thereof downward, and the folded lower portion 2a.
An extending portion 25b extending outward from the lower end of 5a is provided. In FIG. 1, S is a space for preventing the folded lower portion 25a from interfering with other members in the left-right direction of the folded lower portion 25a of the roof plate 24 as described later . That is, adjacent
Error in the installation interval between the hangings and the error in molding the roof plate
Therefore, the displacement of the roof plate that occurs when the roof plate is fixed is allowed.
It is a displacement allowable space that can The folded portion 25a is
Due to this space S, a portion which is not interfered with by other members is reserved over both the inner side and the outer side, and is disposed on the fixed portion 21a of the lower member 21 of the suspension member 20 . In this embodiment, in order to form the flat roof surface by fixing the flat surface portion 26a of the cover member 26, a stepped portion 24a having a predetermined width and depth is provided at the contact portion of the flat surface portion 26a. It is provided.

In order to use the hangings 20 and the roof plate 24 to make a thatched roof, first, the roof plate 24 is placed on the base 11.
The lower member 21 of the suspender 20 is arranged and fixed at a predetermined interval so as to correspond to the width dimension of the inner layer material 6 and then the inner layer material 6 is laid between the adjacent lower members 21 of the suspenders, and then the roof plate 24 is arranged. To go.

Next, the upper member 22 is attached to the pair of engaging arm portions 2.
2d and 22d are elastically attached to both engaging wall portions 21 of the lower member 21.
It is fitted between c and 21c, engaged and held by the engaging claws 21d and 21d, and finally the cover member 26 is engaged with the upper member 22 as described above.

When the upper member 22 is fixedly engaged with the lower member 21 in this manner, the pressing portion 22b of the upper member 22 clamps and pushes the roof plate extending portion 25b between the lower member fixing portion 21a and the lower member fixing portion 21a. The roof plate 24 is attached to the hanger 20 with sufficient bonding strength to withstand the action of wind pressure. Therefore, even if the roof plate 24 has a twist or the like that is produced during manufacturing, this is reliably corrected by being firmly fixed to the hanger 20 at the roof plate extension portion 26b.

Further, since the cover member 26 is independently fixed to the suspension upper member 22 without being affected by the mounting state of the roof plate 24, the fixing can be surely performed and the cover member 26 can be surely fixed. Even if the twist 26 is present, it can be straightened under the positive fixing structure like the roof 24.

In the vertically-roofed roof structure constructed in this manner, the space S shown in the figure prevents the folded lower portion 25a from being interfered by other members in the left-right direction of the folded lower portion 25a of the roof plate.
