Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure of a roof panel which can regulate a flow path of rainwater and perform a stable drainage treatment on a roof having a dome-shaped roof or the like.

[0002]

2. Description of the Related Art Conventionally, when a roof having a dome-shaped roof shape or the like is constructed using a roof panel, a fixed-shaped material (a cover material made of resin, a metal of the same quality as the roof, etc.) or an irregular-shaped material (such as a cover material made of metal of the same quality as the roof) is used for connecting portions. Raining was performed by disposing a sealing material such as rubber). For example, as shown in FIGS. 18 and 19 of Japanese Patent Publication No. Hei 5-63587, a space between the connecting portions is used as a drain groove 29, and a plate made of a zinc iron plate, a stainless steel plate, aluminum, and a waterproof sheet is provided in the drain groove 29. There has been proposed a structure in which a sealing material 57 (regular shaped material) or a silicone-based sealing material 9 (irregular shaped material) is additionally provided.

[0003]

However, in the above configuration, the roof panel is subject to thermal expansion and contraction and shaking due to an earthquake or the like.
There is a problem in that gaps due to cracks and breaks are generated in the shaped material and the unshaped material, and waterproofness is impaired. That is, in the structure using the plate-shaped sealing material 57 in FIGS. 18 and 19 of Japanese Patent Publication No. 5-63587, since it is fixed to the peripheral frame member 2 with an adhesive, the displacement of the plate-shaped sealing material 57 due to shaking. Problems such as peeling occur. In addition, since the bottom of the drain groove 29 is formed at the same level, the roof panel 1
In the corner gathering portion (for example, FIG. 13 and the like), the connection between the plate-shaped sealing members 57 must be performed in a watertight manner, so that the work is extremely troublesome. Further, in particular, a cover material made of resin and a sealing material such as rubber have a problem of deterioration over time. That is, Japanese Patent Publication No. Hei 5-63587, No. 18,
In FIG. 19, it is necessary to substantially rely on the sealing member 9 for waterproofing. However, if the weather resistance is not sufficient, the deterioration of the material directly leads to the breakdown of the waterproofing property.

The lower horizontal piece 152 is formed of the upper heat insulating material 131. Along the surface. The second frame 16 is provided with a second locking horizontal piece 161 that extends rightward at the lower end of the short fixed vertical piece toward the eaves and whose tip is bent obliquely upward. The second locking horizontal piece 161 is substantially flush with the surface of the upper heat insulating material 131 at an interval,
The ridge end of the water stopping member 5 described later is engaged. The third frame 17 is provided with a third locking lateral piece 171 that extends substantially horizontally from the eave end of the short piece-shaped fixed lateral piece, and laterally draining holes 172 and 173 on the ridge side and the eave side. The third locking lateral piece 171 is substantially flush with the surfaces of the panels 1A and 1B and engages with the eaves edge of the water blocking member 5 described later. Then, in one configuration surface, the panel 1A and the panel 1B
And are alternately arranged in the lateral direction and the flow direction.

FIG. 2 shows a connection structure between panels 1A and 1B which are adjacent to each other in the flow direction. A first gutter member 2 is provided between panels 1A and 1B which are arranged at a fixed interval.
Are provided, and the water blocking member 5 covers the gap. The first gutter member 2 has a cross section larger and deeper than the flowing water member 12. In the illustrated embodiment, the ridge side surface 22 that rises substantially vertically from the flat bottom surface 21 is the heat insulating material 1.
A substantially horizontal fixed portion 2 provided at the tip of the eaves side surface 23 which is almost the same height as the thickness of the eaves 31 and rises in an inclined manner.
4 extends to the upper surface end of the panel 1B. still,
At the upper end of the ridge side surface 22, a water return piece is provided bent toward the eaves side. The water-stopping member 5 is made of resin or metal of the same quality as the roof panel 11, and has a decorative surface portion 51 in which a mountain shape and a flat shape are combined, and a ridge side in which the ridge end of the decorative surface portion 51 is folded stepwise. An eaves side engaging part 53 is formed by folding an eaves edge of the decorative surface part 51 from below. At the tip of the ridge-side engaging portion 52, an engaging piece 521 that is folded substantially horizontally toward the eaves side is provided.

The connection structure shown in FIG. 1 can be constructed as follows. First, the panel 1A and the panel 1B having the above-mentioned configuration are fixed to a beam 9 of a building (not shown in the figure, but the upper end thereof is shown in FIG. 4) at a constant interval. Then, the fixing members 182, 18 of the panels 1A, 1B
The L-shaped steel members 7 and 7 are fixed to the upper part of the end face of 2, and a two-layer closing member 8 of a hard wood chip cement plate having the same thickness as the heat insulating material 13 is laid thereon. In this state, the surface of the heat insulating material 132 in the middle stage of the panel 1A, the surface of the closing material 8, and the panel 1B
The surface of the middle heat insulating material 132 becomes flush, and the protruding portion of the waterproof sheet material laid on the surface of the upper heat insulating material 131 of each panel 1A, 1B is polymerized on the closing material 8.
The L-shaped steel member 7 may be integrally attached to the fixing member 182 in advance as a component of the panels 1A and 1B. Next, the first gutter member 2 having the above-described configuration is arranged at the interval between the panels 1A and 1B.
Is inserted into a lateral groove portion surrounded by the upper surface of the middle heat insulator 132, the end surface of the upper heat insulator 131, and the lower surface of the lower horizontal piece 152 of the first frame 15, and the fixed portion 24 of the eave side surface 23 is connected to the third frame 17 Are attached in series when fixing. In the illustrated embodiment, since screws and the like are fixed via the sealing material, water does not enter the back surface of the fixed portion 24, that is, the back surface of the first gutter member 2. After that, the water blocking member 5 having the above-described structure is attached, and the eaves side engaging portion 53 is attached to the third position.
In the state of being engaged with the third locking horizontal piece 171 of the frame 17, while reducing the width of the decorative surface portion 51 against elasticity, the first
The first locking horizontal piece 151 of the frame 15 and the second frame 16
When the ridge-side engaging portion 52 is inserted into the lateral groove portion formed by and, the engaging piece 521 of the ridge-side engaging portion 52 is positioned inside the second locking lateral piece 161 of the second frame 16. To elastically engage. In the illustrated embodiment, a gasket is interposed when the ridge-side engaging portion 52 is inserted so that the ridge-side engaging portion 52 can be stably engaged by the elasticity of the gasket.

In the thus constructed connection structure, the rainwater flowing from between the roof plates 11 constituting the panel 1A on the ridge side flows down the flowing water member 12 and enters the first gutter member 2. Since the one gutter member 2 has a larger cross section and is formed deeper than the flowing water member 12, rainwater does not flow backward. In addition, panels 1A and 1B can be used over time.
Even if the arrangement interval is shifted or the seal material is deteriorated and a gap or the like is generated, rainwater is surely guided to the first gutter member 2 and the waterproof property is not impaired. Then, the rainwater is guided to another gutter member described later. In this way, the rainwater that has flowed down the running water member 12 of the panel 1A on the ridge side does not flow into the first gutter member 2 and does not directly enter the downflow member 12 of the panel 1B on the eaves side. No water leakage or the like will occur in the downflow member 12. That is, if the first gutter member 2 is not provided, the rainwater flows directly from the running water member 12 of the panel 1A on the ridge side to the running water member 12 of the panel 1B on the eaves side, so that an enormous amount of rainwater flows downstream (eave side). Will be concentrated and water will be more likely to leak. Note that the first gutter member 2 is arranged in a direction substantially perpendicular to the flow direction, and has a depth that is not greater than other gutter members described later. Although rainwater may flow in, in the illustrated embodiment, when the amount of rainwater that has entered the first gutter member 2 exceeds a certain amount, excess water is drained from the drain holes 172 and 173 provided in the third frame 17. Rainwater can be discharged (overflow) onto the surface of the panel 1B on the eaves side.

FIG. 3 shows a connection structure between a panel 1B and a panel 1A which are adjacent to each other in the horizontal direction. A second gutter member 3 is arranged between the panels 1B and 1A which are arranged at a constant interval. The water blocking member 5 covers the gap. Second
The gutter member 3 has a cross section larger and deeper than the first gutter member 2, and an inclined slope 35 and a substantially horizontal receiving surface 36 are interposed between the ridge side surface 32 and the bottom surface 31. The first gutter member 2 has substantially the same shape as the first gutter member 2 except that the eave side surface 33 having a fixed portion 34 at a point and a tip is vertical. The slope 35 has substantially the same height as the thickness of about three layers of the heat insulating material 13, and the ridge side surface 32 has substantially the same height as the thickness of the heat insulating material 131 in the upper stage. Reference numeral 3 has a depth substantially equal to the thickness of about four layers of the heat insulating material 13.

The connection structure shown in FIG. 1 is provided at the end faces of the fixing members 182, 182 of the panels 1B, 1A disposed at a position below the upper end by the thickness of the heat insulating material 13 by about three layers. , 7 are fixed, and the blocking structure 8 is laid thereon. The mounting structure on the ridge side and the eave side of the second gutter member 3 and the engaging structure on the ridge side and the eave side of the water stop member 5 are also described above. Since the connection structure is the same as the connection structure using the first gutter member 2, it can be constructed in the same manner as described above. The L-shaped steel material 7 is the panel 1
B and 1A may be integrally attached to the fixing member 182 in advance as one component.

Even in the connection structure constructed in this manner, rainwater enters the second gutter member 3 from the running water member 12 of the panel 1B on the ridge side. Therefore, the rainwater does not flow backward and does not directly enter the downflow member 12 of the eave-side panel 1A. Rainwater also flows into the second gutter member 3 from the first gutter member 2.
Since the gutter member 3 has a larger cross section and is formed deeper than the first gutter member 2, rainwater can flow down reliably to the eaves side without backflow. That is, when the backflow of rainwater occurs in the first gutter member 2, even if excess rainwater is discharged from the drain holes 172 and 173 provided in the third frame 17 as described above, particularly, in the downstream direction (eave tip) On the side), a large amount of rainwater is concentrated, so that water leakage or the like in the flowing water member 12 is likely to occur. In other words, the second gutter member 3 suppresses the backflow and the overflow of the first gutter member 2 and indirectly prevents water leakage or the like in the flowing water member 12.

FIG. 4 shows a connection structure between panels 1A adjacent to each other on the left and right sides in different configuration planes.
A third gutter member 4 is arranged between the panels 1A, 1A arranged at a fixed interval, and the interval is covered by a water blocking member 5 '. In the figure, the panels 1A, 1
Although A is drawn to form one flat surface, more specifically, the other panel A is constructed and constructed so as to be inclined with respect to one panel 1A. The third gutter member 4 has a larger cross section and is formed deeper than the second gutter member 3, and may be a long continuous material or a fixed-length material. In the illustrated embodiment, a flat bottom surface 41, a side surface 42 that rises substantially vertically from the left and right side edges of the bottom surface 41,
Receiving surface 4 extending substantially horizontally outward from the upper end of the side surface 42
6 and a second rising from the tip of the receiving surface 46 in a substantially vertical shape.
The second side surface 43 is provided with a water return piece that is bent inward at the upper end of the second side surface 43. Since the side surface 42 has substantially the same height as the thickness of about five layers of the heat insulating material 13 and the second side surface 43 has substantially the same height as the thickness of the heat insulating material 131 in the upper stage, the third gutter is used. The member 4 has a depth substantially equal to the thickness of about six layers of the heat insulating material 13. The water-stopping member 5 ′ is formed on the left and right side edges of the substantially flat decorative surface portion 51 by slightly bending upward and extending the upper end outward in a substantially horizontal manner.
4 and 54 are provided.

In the connection structure shown in the figure, first, the panels 1A, 1A having the above-mentioned configuration are arranged at predetermined intervals on a beam 9 of a building, and an L-shaped steel material is provided at the lower end of the side surface of the fixing members 182, 182. 7, 7 are fixed, and the closing material 8 is laid thereon. Next, the third gutter member 4 having the above-described configuration is disposed at the facing interval between the panels 1A and 1A, in which case the bottom surface 41 is received by the upper surface of the closing member 8 and the second side surface 43 is heat-insulated in the middle stage. It is attached so as to be inserted into a lateral groove portion surrounded by the upper surface of the material 132, the end surface of the upper heat insulating material 131, and the lower surface of the flowing water member 12. It has been described that the third frame 17 is attached to the two sides of the panel 1A on the ridge side when the roof is constructed. However, as shown in FIG.
It is not necessary to attach the third frame 17 to the end of A. Thereafter, the water-stopping member 5 'having the above-described configuration is applied. The side portions 54, 54 are overlapped with the upper surface ends of the panels 1A, 1A, and screws or the like are attached via a sealing material. Fix by doing.

Even with the connection structure thus constructed, rainwater flows from the first gutter member 2 into the third gutter member 4, but the third gutter member 4 is formed to have a larger cross section and a greater depth than the first gutter member 2. As a result, rainwater can reliably flow down to the eaves without backflow. In addition, since the third gutter member 4 has a larger cross section and is deeper than the second gutter member 3, rainwater flowing down in the third gutter member 4 may flow into (branch into) the second gutter member 3. It is possible to surely make it flow down to the eaves side. That is, when rainwater flowing down in the third gutter member 4 flows (branches) into the second gutter member 3, the second gutter member 3
In some cases, rainwater exceeding the allowable amount may be concentrated, which may easily cause a backflow or an overflow in the first gutter member 2 before that, a water leak in the flowing water member 12, or the like. In other words, the third gutter member 3 includes the second gutter member 3 and the first gutter member 2.
In this way, backflow and overflow of the water flowing member 12 are suppressed, and water leakage in the flowing water member 12 is indirectly prevented.

The eaves gutter member 6 arranged along the eaves of the roof
Has a larger cross section and is formed deeper than the third gutter member 4, and its structure is not particularly limited. For example, the right half portion of the first gutter member 2 in FIG. The left half may have a structure and may be simply a vertical side wall surface. Rainwater enters the eaves gutter member 6 from each of the flowing water member 12, the second gutter member 3, and the third gutter member 4. The cross section is larger and deeper than any of these members 12, 3, and 4. Since it is formed, rainwater can be reliably guided to a not-shown downspout or the like and discharged downward without flowing backward.

FIG. 5 shows a connecting portion of the first gutter member 2, the second gutter member 3 and the third gutter member 4, and the construction of each of the gutter members 2, 3 and 4 is simplified and drawn. There is. The connection of the gutter members 2, 3, 4 is carried out by cutting out a part (upper part) of the side wall of the large gutter, and specifically, the third gutter member 4.
The second gutter member 3 is placed by being cut downward from the upper end of the side wall of the second gutter member 3 by the depth of the second gutter member 3, and by the depth of the first gutter member 2 from the upper end of the side wall of the second gutter member 4. Notch down first
The gutter member 2 is placed. The first gutter member 2 and the second gutter member 3
Guide pieces 27, 37 in the form of short pieces inclined downward from the bottom surfaces 21, 31 are provided at the edges in the flow direction of the guide pieces 27, 3
7 is located inside the third gutter member 4. still,
Second gutter member 3, third gutter member 4, eave gutter member 6 at the eaves
Is the same as above.

The present invention has been described above based on the embodiments of the drawings, but the present invention is not limited to the above embodiments and can be carried out in any manner as long as the configuration described in the claims is not changed. be able to. For example, in the above-described embodiment, the roof panel 1 has a regular triangular shape. However, the present invention is not limited to this, and may be, for example, a square shape. In the above-described embodiment, the waterproof members 5, 5 'are of a fixed shape made of resin or metal of the same quality as the roof panel 11, but for example, a roof having a double structure in which a cover material is provided above the roof. For example, an irregular shaped material such as a silicone rubber may be used.

[0021]

As described above, the connection structure of the roof panel according to the present invention has a gutter member at the connection portion, so that the roof panel is displaced due to use over time, the sealing material is deteriorated, and a gap is generated. However, since the rainwater is surely guided to the gutter member, the waterproofness is not impaired. Moreover, since the cross section and the depth of the gutter member arranged at the connection portion are different, it is possible to regulate the rainwater flow path and perform stable drainage treatment.
