DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a vertical roof structure.

[0002]

2. Description of the Related Art The conventional structure of a vertical thatched roof is generally one in which the side edges of vertically adjacent thatched roof plates are fixed to the base via suspension members. In this case, in order to waterproof the connecting portion between the adjacent roof plates, the connecting portion is covered with a cover member, or a roof plate integrally formed with the cover portion is used. (Publication documents of this type of exterior structure include, for example, Japanese Utility Model Publication No. 63-28718 and Japanese Utility Model Publication No. 3-31626.
See the issue. ) However, according to this type of thatched roof structure so far, when the connection part of the roof plate is flooded, or when dew condensation occurs on the back surface of the connection part, the water from the connection part falls onto the base, There was a risk of invading the room as it was.

Further, when a constant-sized roof plate is connected in the flow direction to form a roof surface, a waste plate is arranged at the connection portion, but the connection is still made when a strong pressure acts due to strong wind. There was a problem that rainwater entered the part and leaked to the indoor side when it exceeded the allowable amount.

The present invention has been made by paying attention to such a conventional problem, and its main purpose is to prevent rainwater and the like from intruding from the connecting portion of the roof plate in the girder direction and the flow direction, which is unlikely to cause dew condensation. On the other hand, it is to provide a vertical roof structure that can reliably prevent water leakage to the indoor side. In addition, the purpose is to increase the strength of the thatched roof, to improve the heat insulation, and to secure the structural reliability against thermal expansion and contraction.

[0005]

In order to achieve the above-mentioned object, as an invention of claim 1, a support member is arranged on the lower ground of the roof, and a vertically-roofed roof plate is formed on both side edges thereof. A vertically-roofed roof structure fixed to the support member via a portion, wherein the support member is provided with a running water space formed along the flow direction and having an open cross section, and is adjacent in the girder direction. A water leakage prevention plate having a substantially corrugated cross-sectional shape when viewed from the flow direction is provided between the support members, and both side edges of the water leakage prevention plate are made to face the running water space of the support member , and The protection plate is inside the roof
The roof plate shall be held indirectly by abutting through a layer material or the like .

[0006] As the invention of claim 2, the roof substrate

Vertical thatched roof fixed to the support member through the formed engaging portion
A root structure, formed on the support member along the flow direction
A running water space with a cross-sectional shape that is open at the top
And the flow between adjacent support members in the column direction.
Water leakage prevention plate having a substantially corrugated cross-sectional shape when viewed from the
And both side edges of this water leakage prevention plate are
When facing the running water space, the water leakage prevention plate is
The back side is directly contacted and held .

Further, as the invention of claim 3, the support member of each of the above inventions is composed of an upper support member to which a roof plate is attached and a lower support member having a running water space, and the upper support member is a lower support member. It shall be supported so as to be slidable in the flow direction.

[0008]

In each of the first and second aspects of the invention, since the waterproof structure in which the running water space of the support member and the water leakage prevention plate are continuous is formed between the roof plate and the base, the roof plate is temporarily Even if water enters from the connection part or the like, it does not leak to the inside of the room, and the invading water flows toward the eaves by the running water space and is discharged.

Further, since a space is inevitably formed between the roof plate and the base by arranging the corrugated water leakage prevention plate, the outside air passes through the space, so that the space below the roof material is Moisture is removed, thereby suppressing the generation of dew condensation, and at the same time, the existence of the space portion enhances the heat insulating effect.

Further, even when the fixed-length roof plate is connected in the flow direction, even if water enters at the connection part in the flow direction due to the running water space of the support member and the water leakage prevention plate, it is possible to leak water to the inside of the room. This can be prevented, and this eliminates the need for the structure of the connection portion to have a complicated waterproof structure.

In each of the above-mentioned inventions of claim 1 and claim 2,
Water leakage prevention plate is indirectly connected to the back side of the roof plate via inner layer material etc.
Since it abuts or holds directly or directly, stronger roof strength is exerted against the load acting on the roof surface.

According to the third aspect of the present invention, even when the roof plate is directly fixed with a screw or the like, the upper support member is provided with the lower support member by arranging the screw fixing portion on the upper support member side. By sliding against the sheet, thermal expansion and contraction in the flow direction can be absorbed, so that deformation of the roof surface, deterioration of strength, and deterioration of waterproofness due to thermal expansion and contraction of the roof plate and the like can be avoided.

Four
3 and an engaging member 44 formed so as to be elastically engaged therewith from above, and a cover member 45 is fitted from above. On the other hand, what is shown in FIG. 13 is different from FIG. 12 in that the suspension member 43 is directly fastened to the lower support member 41 via the bolt nut 8 without providing the upper support member 42.

Next, the function and effect common to the embodiments having various modes described above will be described.

That is, according to the configuration of each of the above embodiments,
A running water space A (see FIG. 1) opened upward is formed by the gutter member 3 forming a part of the support member 41 between the roof plate 6 and the field material 2 forming the roof base, and this running water is also formed. The space A and the water leakage prevention plate 5 with both edges 5e facing the space A form a waterproof structure that is continuous in the column direction. Therefore, even if water intrudes from the connecting portion of the roof plate 6 or the like, it does not leak to the indoor side, and the invading water flows toward the eaves of the roof in the running water space A and is discharged.

By arranging the corrugated water leakage prevention plate 5, a space is inevitably formed between the roof plate 6 and the field material 2, so that the outside air can pass through the space. Roofing material 6
The lower moisture is removed, which suppresses the generation of dew condensation, and at the same time, the existence of the space portion enhances the heat insulating effect.

Further, even in a vertically-roofed roof structure in which a plurality of fixed-size roof plates 6 are connected to each other to secure a roof size in the flow direction, the flowing water space A and the water leakage prevention plate 5 prevent the flow direction from changing. Even if water invades at the connection part, it can be surely prevented from leaking to the inside of the room, and it is not necessary to make the structure of the connection part into a complicated water resistant structure. A simple connection structure as illustrated in 15 can be used.

In the figure, reference numeral 11 denotes a gutter-shaped joint waste plate arranged along the girder direction so as to be located at the connection portion of the standard length roof plate 6 in the flow direction, and an end 11a in the girder direction is a gutter. It is provided so as to face the flowing water space A of the member 3. A fixing member 12 made of an elastic material such as rubber and provided with two adjacent holding portions 12a is attached to the bottom surface of the central portion of the joint discarding plate 11 in the row direction. On the other hand, the roof plate 6 has a folded portion 6e formed at the front and rear ends of the flat portion 6a in the flow direction, and the eaves side and ridge side folded portions 6 of the roof plate 6 adjacent to the flow direction in the flow direction.
By holding the holding member 12 with the holding portion 12a of the fixing member 12, a plurality of fixed-size roof shingles 6 are connected in the flow direction.

In such a structure, even if rainwater intrudes from the connecting portion B (see FIG. 14) in the flow direction, the rainwater is received by the joint wasteboard 11 and the end portion 11a thereof is received. It is discharged into the running water space A of the gutter member 3. Also, even if rainwater overflows from the joint waste plate 11 or dew condensation water is generated on the back side of the roof plate 6, these waters are received by the water leakage prevention plate 5, After all it is discharged to the eaves direction. Therefore, even with such a simple connection structure, it is possible to reliably prevent water leakage to the indoor side.

On the other hand, the roof plate 6 is directly held by the upwardly convex holding portion 5a provided on the water leakage prevention plate 5, or indirectly by the inner layer material 7 and the backing material 10. Since the load acting from the upper surface side of the roof plate 6 can be supported by the roof substrate (in this case, the field material 2 and the main material 1) via the water leakage prevention plate 5, the load bearing strength of the roof is further improved. Can be made. In each embodiment, the holding portion 5a has a trapezoidal shape with a flat upper surface, but the holding portion 5a is not limited to this, and the holding portion 5a may have a curved waveform shape.

Further, as in the embodiment shown in FIG. 1 and FIGS. 3 to 12, the upper support member 42 with respect to the lower support member 41.
When the structure is configured to support slidably in the flow direction,
Even when the roof plate 6 is directly fixed with screws or the like, the upper support member 42 slides with respect to the lower support member 41 by locating the screw fixing point on the upper support member 42. Since the heat expansion and contraction in the flow direction is allowed, the deformation and strength decrease of the roof surface due to the heat expansion and contraction of the roof plate 6 and the like,
It is possible to avoid deterioration of waterproofness.

By the way, in each of the above-described embodiments, the running water space A is formed by the gutter member 3 forming a part of the lower support member 41, but by forming the lower support member 41 itself as a long member. The groove 41a can be used as the running water space A, whereby the gutter member 3 can be discarded. As shown in FIGS. 2, 11, and 13, in the structure in which the lower support member 41 is penetrated to fasten a fixture such as a bolt, intruding water may leak downward from the penetrating portion. In this case, it is desirable to provide the gutter member 3. However, when the bolt or the like as the fixture does not penetrate the support member 41 and is erected by welding or welding, there is no risk of water leakage, and therefore the gutter member 3 can be omitted.

Also, as the roof substrate of the embodiment, the main material 1
Although the field material 2 is laid on the roof, the present invention is not limited to this, and the field material 2 can be configured on a roof foundation such as an RC structure.

According to each of the first and second aspects of the invention, there is provided a support member having a running water space formed along the flow direction and having a cross-sectional shape with an open upper part, as a trough member or integrally. A water leakage prevention plate having a substantially corrugated cross-sectional shape when viewed from the flow direction is provided between support members adjacent to each other in the girder direction in addition to being arranged on the roof base, and both side edges of the water leakage prevention plate are supported by the above-mentioned support. By facing the running space of the member, a continuous waterproof structure including the supporting member and the water leakage prevention plate is formed between the roof plate and the base,
Even if water enters from the connecting portion of the roof plate or the like, the water can be discharged to the outside through the running water space and can be reliably prevented from leaking to the indoor side.

Further, since the space between the roof plate and the base is secured by the corrugated water leakage prevention plate, the generation of dew condensation is suppressed by the outside air flowing through the space, and the heat insulating effect is enhanced. To be

Further, even when the fixed-length roof plates are connected in the flow direction, the waterproof structure by the support member and the water leakage prevention plate can reliably prevent water leakage to the indoor side, and the structure of the connection portion is simple. Can be converted.

In each of the first and second aspects of the present invention,
Is the water leakage prevention plate on the back side of the roof board through the inner layer material, etc.
Since it holds this by contacting it indirectly or directly,
Stronger roof strength against the load acting on the roof surface
Is done.

Further, according to the invention of claim 3, since the upper supporting member having the roof plate mounting portion is slidable in the flow direction with respect to the lower supporting member having the running water space, Even when it is stopped directly with a screw or the like, the structural reliability can be improved by avoiding the deformation of the roof surface, the reduction in strength, and the reduction in waterproofness due to the thermal expansion and contraction of the roof plate and the like.
