The present invention relates to a roof structure having an eaves gutter.

In recent years, as a roofing material such as roofs and eaves of buildings, panels made by increasing the strength of a lightweight aluminum plate with a honeycomb structure or the like, which is excellent in corrosion resistance, have been widely used. For example, in eaves 110 shown in FIG. 12, panels 111 are supported by support beams 115 on wall surfaces 113 of the building. A gutter member 117 is provided at the tip side edge of the panel 111 so as to receive rainwater flowing on the upper surface of the panel 111 with the gutter member 117 .

FIG. 13 is a schematic cross-sectional view of a connecting portion between the panel 111 and the gutter member 117. As shown in FIG. The panel 111 is configured by sandwiching a core member 121 such as a honeycomb core and a frame member 123 surrounding the core member 121 between two face plates (an upper face plate 127A and a lower face plate 127B). Outside the frame member 123, a gutter member 117 is arranged along the longitudinal direction of the frame member 123 (the depth direction in FIG. 13). The gutter member 117 is fixed to the side surface of the frame member 123 with screws 133 . A gap between the upper surface plate 127A and the side wall 131 of the gutter member 117 is filled with a sealing material 137 to prevent rainwater from dripping downward from the gap.

An embodiment of a roof structure with eaves gutters according to the present invention will be described below in detail with reference to the drawings.

<First embodiment>
FIG. 1 is an overall configuration diagram of a roof structure with an eaves gutter according to a first embodiment of the present invention.
A roof structure 100 with an eaves gutter has a panel member 10, a gutter member 30 fixed to the panel member 10, and a frame 13 fixing the panel member 10 in a suspended state. In the panel member 10, a plurality of (two in the illustrated example) panels 11 are connected with their sides facing each other. The frame 13 is formed in an inverted L shape, and one or more (three in the illustrated example) are arranged. In the drawings, the Y direction is the connection direction of the panel 11, the Z direction is the height direction, and the X direction is the direction orthogonal to the Y and Z directions.

The frame 13 is made of, for example, a steel material such as H-section steel, an aluminum alloy, or the like, and includes a leg portion 13a and a beam portion 13b extending substantially horizontally from the upper portion of the leg portion 13a. The illustrated shape of the frame 13 is merely an example, and is not limited to the illustrated shape or arrangement of each part.

The panel member 10 having two panels 11 is supported by the beam portion 13b of the frame 13 and is inclined downward from the horizontal plane in the direction (X direction) extending from the leg portion 13a of the beam portion 13b. Each panel 11 is connected to each other in a direction (Y direction) orthogonal to the tilt direction of the panel 11, with the panel ends facing each other. Further, each panel 11 is provided with an elongated gutter member 30 along the edge on the lower side of the inclination. The panel member 10 is not limited to the two panels 11 shown in the figure, and may have a configuration in which three or more panels 11 are connected.

FIG. 2 is a schematic perspective view of the panel 11 showing the internal structure with a part of the panel 11 cut away.
The panel 11 includes a rectangular plate-shaped core member 14, a frame member 17 arranged to surround the core member 14, and an upper plate 21 and a lower plate 21 that sandwich the core member 14 and the frame member 17 in the plate thickness direction and fix them. A face plate 23 is provided.

The core member 14 has a honeycomb structure as a core material, in which walls made of aluminum or an aluminum alloy are erected in a honeycomb shape. Since the core member 14 is a honeycomb structure, it can be made lightweight and highly rigid.

The frame member 17 is a frame body having the outermost edge at the same position as the outer edges of the upper plate 21 and the lower plate 23 or inside the outer edges, and is made of, for example, an aluminum or aluminum alloy profile, a rectangular bar, or the like. Both ends of the core member 14 and the frame member 17 in the thickness direction are adhered to the upper plate 21 and the lower plate 23 with the adhesive 19 applied to the upper plate 21 and the lower plate 23, respectively.

The upper plate 21 and the lower plate 23 are aluminum or aluminum alloy plates, and may be iron plates, stainless steel plates, resin plates, CFRP plates, etc., or plate materials in which these are appropriately combined.

The thickness of the core member 14 is approximately 3 mm to 300 mm. The thickness of the upper plate 21 and the lower plate 23 is 0.2 mm to 3.0 mm, preferably 1.5 mm to 2.5 mm. A plurality of support bolts 25 such as stud bolts are provided on the side of the top plate 21 fixed to the frame 13 (see FIG. 1). Each support bolt 25 is provided at appropriate intervals according to the frame 13 and fastened to the mounting bracket 12 provided on the beam portion 13b of the frame 13 . As a result, the panel 11 is supported by the beams 13b of the frame 13. As shown in FIG.

Although the details will be described later, the upper plate 21 has a longer side in the X direction than the lower plate 23 on the side of the gutter member 30 .

FIG. 3 is a cross-sectional view of the panel 11 shown in FIG. 1 taken along line III--III. FIG. 4 is a perspective view showing the support structure of the gutter member 30 shown through the top plate 21. As shown in FIG.
As shown in FIGS. 3 and 4, the top plate 21 of the panel 11 has a top plate extension 41 extending in the X direction, ie, toward the gutter member 30 .

The gutter member 30 is a member having a concave longitudinal (Y-direction) cross-section having a bottom wall 31 and side walls 33a and 33b rising from both side edges of the bottom wall 31 in the Z direction. An opening is provided above the bottom wall 31 of the gutter member 30, and this opening is partially covered by the upper surface plate extension 41. As shown in FIG. The opening 35 between the side wall 33b of the gutter member 30 and the edge of the upper plate extension 41 on the inclined downward side has a Y-direction width of 10 mm to 100 mm, preferably 30 mm to 40 mm. be done. This width dimension does not prevent rainwater from flowing into the gutter member 30 from the extension 41 of the upper surface plate.

Further, the side wall 33 b of the gutter member 30 has its upper end raised to a position higher than the edge of the upper surface plate extension 41 . As a result, when rainwater flows into the gutter member 30 along the upper surface of the panel 11, the flow over the side wall 33b and passing the gutter member 30 can be suppressed, and the rainwater can be surely guided to the gutter member 30.例文帳に追加

The gutter member 30 is supported by the top plate extension 41 of the panel 11 . Support members 43 are attached to a plurality of locations along the longitudinal direction of the gutter member 30 . The supporting member 43 has a shape obtained by bending a rectangular plate into a hat shape, and a raised central portion of the supporting member 43 serves as a fixing portion 45 to be fixed to the upper surface plate extension portion 41 . A bolt insertion hole 45a is formed in the fixing portion 45, and a nut (pop nut) 58 is fixed to the bolt insertion hole 45a. A bolt 47 is attached to the nut 58 .

The side walls 33a and 33b of the gutter member 30 are provided with fixing pieces 49a and 49b on the sides of the side walls 33a and 33b facing each other in the vicinity of the upper edge. The fixed pieces 49a and 49b are formed along the longitudinal direction of the gutter member 30, and both ends of the support member 43 are fixed by bolts 51 and nuts 53. As shown in FIG. As a result, the support member 43 is fixed to the gutter member 30 in a state of being bridged across the opening of the gutter member 30 in the width direction.

A bolt 47 provided at a fixed portion 45 of the support member 43 is inserted into a hole 41a formed in the upper plate extension portion 41, and a nut 56 is fastened from above the upper plate extension portion 41. As shown in FIG. Thereby, the gutter member 30 is fixed to the upper surface plate extension portion 41 .

After fixing the support member 43 to the fixed pieces 49a and 49b of the gutter member 30 in this manner, the support member 43 and the upper plate extension 41 are fastened with the bolts 47 and nuts 56, which is a simple operation. The gutter member 30 can be supported on the top plate extension 41 of the panel 11 .

The frame member 17 of the panel 11 is formed with recesses 17 a and 17 b at the corners of the top plate 21 and the bottom plate 23 . Seal members 18A and 18B are provided in the recesses 17a and 17b. That is, the space between the top plate 21, which is the base end side of the top plate extended portion 41, and the frame member 17 is watertightly sealed by the sealing member 18A. As a result, even if rainwater flows into the back side of the upper surface plate extension portion 41, the rainwater is prevented from entering the panel 11 by the sealing member 18A. Also, the seal member 18B between the lower plate 23 and the frame member 17 prevents rainwater from permeating into the panel 11 along the lower plate 23. As shown in FIG. Thus, in the panel 11, the gaps between the top plate 21 and the bottom plate 23 and the frame member 17 are reliably sealed by the sealing members 18A and 18B. Since these sealing members 18A and 18B are assembled to the frame member 17 when the panel 11 is manufactured, a sealing process is not required when constructing the roof structure.

FIG. 5 is a view of the panel member 10 shown in FIG. 1 as viewed from the direction P1.
A notch portion 61 is formed at a connecting portion between the panels 11 in the upper surface plate extension portion 41 of the two panels 11 of the panel member 10 . The notch portion 61 opens the upper portion of the gutter member 30 widely at the connecting portion between the panels 11 . In addition, a lid member 55 is fitted along the connection side of the panels 11 at the connection point between the panels 11 to close the gap between the upper surface plates 21 in a watertight manner.

FIG. 6 is a plan view of the portion of the drop opening 63 provided in the gutter member 30. As shown in FIG. FIG. 7 is a cross-sectional view taken along line VII--VII shown in FIG.
The gutter member 30 has a drop opening 63 formed at an appropriate position for guiding rainwater flowing down the bottom wall 31 downward. A drain 65 extending downward is connected to the drop port 63 . A drain pipe 67 is provided below the drain 65 , and the lower end of the drain 65 is inserted into an opening 69 of the drain pipe 67 . Rainwater accumulated in the gutter member 30 flows into the drain pipe 67 through the drain 65 , and the rainwater that has flowed in is drained through the drain pipe 67 . Here, a notch portion 71 is formed at a position above the drop opening 63 in the upper surface plate extension portion 41 of the panel 11 . The notch portion 71 opens the upper portion of the gutter member 30 widely at the location where the drop opening 63 is formed.

As described above, the upper surface plate extension 41 is formed with a notch 61 above the connection position between the panels 11 and a notch 71 above the drop opening 63 . By providing these notch portions 61 and 71, it is possible to easily take out the dust accumulated in the rainwater flow path in the gutter member 30, thereby improving maintainability.

According to the roof structure 100 with eaves gutters described above, the rainwater that has fallen on the upper surface of the panel member 10 flows on the upper surface plate 21 toward the lower inclined side of the panel, and the upper surface plate extended portion 41 flows toward the lower inclined side of the panel. It flows into the gutter member 30 through the opening 35 opening at the edge. The rainwater that has flowed into the gutter member 30 is sent to a drain pipe 67 from a drop port 63 provided in the gutter member 30 and drained.

Since the opening of the gutter member 30 provided at the edge of the inclined lower side of the panel 11 is partially covered by the upper surface plate extension part 41, dirt such as dead leaves and the like is prevented from entering the flow path of the gutter member 30 along with rainwater. entry is inhibited. As a result, while maintaining the flow of rainwater from the upper surface plate 21 to the gutter member 30, it is possible to prevent the drainage of the gutter member 30 from being blocked by dust or the like. Moreover, according to this configuration, compared with a structure in which the opening of the gutter member 30 is covered with a separate member such as a net to prevent dust from entering, the configuration can be made at low cost and excellent in appearance.

Since the upper side of the gap between the frame member 17 of the panel 11 and the gutter member 30 is covered with the protruding upper surface plate extension portion 41, the space between the frame member 17 of the panel 11 and the gutter member 30 is sealed with a sealing material. eliminates the need for a watertight structure. Therefore, it is possible to eliminate the time-consuming and complicated installation of the sealing material, and complete the assembly and installation of the roof structure with the eaves gutter in a shorter period of time than before. In addition, there is no need to manage the deterioration of the sealing material even after installation, and maintainability can be improved.

Further, since the gutter member 30 is directly supported below the upper surface plate extension portion 41, the structure for supporting the gutter member 30 on the panel 11 can be greatly simplified. Therefore, the number of parts of the connecting portion can be reduced, and the equipment cost and construction cost can be reduced. Moreover, the gutter member 30 can be easily attached to the panel 11 by fixing the gutter member 30 to the upper surface plate extension part 41 via the support member 43 that bridges the opening of the gutter in the width direction (X direction). . Further, since the fixing portion 45 of the support member 43 is fixed to the upper plate extension portion 41, the gutter member 30 can be supported by the upper plate extension portion 41 in a well-balanced manner at its center of gravity.

Further, seal members 18A and 18B are provided at the corners of the frame member 17 and the top plate 21 and the bottom plate 23, which are covered by the top plate extension portion 41. As shown in FIG. Therefore, even if rainwater flows into the inner surface side of the upper surface plate extension portion 41 due to strong winds or the like, the seal members 18A and 18B can reliably prevent water from entering the inside of the panel 11 .

Further, in the gutter member 30, the upper end of the side wall 45b on the side opposite to the panel 11 is higher than the edge of the upper surface plate extension 41 on the inclined downward side. As a result, when rainwater flows along the upper surface of the panel 11 into the gutter member 30, the rainwater is prevented from overflowing from the gutter member 30. - 特許庁

As fixing means for fixing the support member 43 to the upper surface plate extension portion 41, fastening members such as illustrated bolts and nuts may be used, but the fixing means is not limited to this. The fixing means may be fastening by rivets, a well-known snap mechanism, or the like, and can be appropriately selected depending on the fixing position and the fixing target. Further, if the gutter member 30 is configured to be easily attached to and detached from the panel 11, adjustment and replacement work of the gutter member 30 can be easily performed.

Further, the upper surface plate extension portion 41 that supports the gutter member 30 may be thicker than the lower surface plate 23 in order to increase the support strength of the gutter member 30 . Furthermore, a reinforcing metal fitting having an L-shaped cross section may be attached to the edge portion of the upper surface plate extension portion 41 on the inclined lower side. In that case, the reinforcing metal fittings serve as guides for guiding rainwater flowing from the upper surface plate extension 41 to the gutter member 30 .

In addition, the upper surface plate extension part 41 can be formed in various forms according to the installation form of the roof and the like. For example, the root portion of the top plate extension 41 may be slightly bent so that the top plate extension 41 is horizontal with respect to the panel 11 inclined from the horizontal plane. In this way, the gutter member 30 supported by the upper plate extension 41 can be easily arranged horizontally. In addition, the strength of the upper surface plate extension portion 41 can be improved due to the increase in section modulus due to bending.

Further, the shape of the gutter member 30 is not limited to the concave cross-sectional shape in which the side walls 33a and 33b are erected on both side edges of the bottom wall 31, and the gutter member 30 is not limited to having an arcuate cross-section or a U-shaped cross-section in which the upper side of the gutter member 30 is open. may be of

(Modification)
Next, a modification of the roof structure with eaves gutter described above will be described.
In the following description, members and portions that are the same as the above-described members and portions are given the same reference numerals, thereby omitting or simplifying the description thereof.

FIG. 8 is a cross-sectional view of the panel taken along line III--III shown in FIG. 1 for explaining a modification.
In this modification, a locking piece 75 projecting toward the panel 11 is provided on the side wall 33a of the gutter member 30 on the panel 11 side, and a locking piece 75 projecting toward the gutter member 30 is provided on the side surface of the frame member 17 of the panel 11. A strip 77 is provided. The locking pieces 75 and 77 position the gutter member 30 and the panel 11 by overlapping each other in the vertical direction and being locked.

A side wall 33a of the gutter member 30 on the panel 11 side is provided with an abutment piece 79 projecting toward the panel 11 side below the locking piece 75 . The abutment piece 79 abuts against the side surface of the frame member 17 of the panel 11 and prevents the gutter member 30 from being displaced toward the panel 11 due to the bending of the upper plate extension portion 41 .

Assuming that the total width dimension of the opening of the gutter member 30 in the width direction (X direction) is La, a region with a width dimension Lc larger than a width dimension Lb (=La/2) that is half of the total width dimension La is the extension of the upper surface plate. It is covered by part 41 . As a result, the gutter member 30 can be fixed to the upper surface plate extension 41 at the center of gravity, which is substantially the center of the opening in the width direction. That is, the gutter member 30 is fixed to the upper surface plate extension 41 by the bolt 47 arranged at the center of gravity of the gutter member 30 with respect to the width direction of the opening. Therefore, even when a large amount of rainwater accumulates in the gutter member 30 and the downward load W increases, the applied load W is stably supported by the bolts 47, and the gutter member 30 does not incline.

Further, even if a load W is applied downward to the gutter member 30 to generate a moment M and a force F directed toward the panel 11 is applied, the abutment piece 79 abuts against the core member 14, so that the gutter member 30 A force F applied to is received by the core member 14 . Therefore, the supporting strength of the gutter member 30 with respect to the panel 11 can be easily improved.

Furthermore, in this modification, when the gutter member 30 is supported by the upper surface plate extension portion 41 of the panel 11, the gutter member 30 is supported by placing the locking piece 75 of the gutter member 30 on the locking piece 77 of the panel 11. can be positioned. By positioning the gutter member 30, the bolt 47 can be fixed to the upper plate extension 41 with good workability.

Set along the edge. The inclination of the panel member 10 in the illustrated example is exaggerated and may differ from the actual inclination. The same applies to other embodiments described below.

According to this configuration, the rainwater that has fallen on the panel 11 flows over the upper surface plate 21 of the panel 11 toward the leg portion 13a of the frame 13, which is the inclined lower side, and the edge of the upper surface plate extension portion 41 on the inclined lower side. The water flows into the gutter member 30 from the part and is drained. In this case as well, the same effect as in the first embodiment described above can be obtained, and maintenance can be easily performed by arranging the gutter member 30 on the side closer to the leg portion 13a.

<Third Embodiment>

In this configuration, the substantially L-shaped connecting fitting 83 joined to the frame member 17 of the panel 11 and the fixed pieces 85 protruding from the side walls 33a and 33b of the gutter member 30A are screwed together, whereby the gutter member 30A can be is fixed to the panel 11 . A guide plate 87 having an L-shaped cross section may be fixed to the edge portion of the upper surface plate extension portion 41 on the lower side of the inclination. In this case, the guide plate 87 smoothly guides rainwater to the gutter member 30A disposed below, and suppresses rainwater from flowing into the inner surface side of the upper surface plate extension portion 41 .

According to this embodiment, the rainwater that has fallen on each panel 11 flows on the upper surface plate 21 toward the support 81 side, and flows into the gutter member 30 from the edge portion on the inclined lower side of each upper surface plate extension portion 41. . The rainwater that has flowed into the gutter member 30 is drained from a drop hole or the like (not shown). In this case as well, the gap between the gutter member 30 and the frame member 17 of the panel 11 is covered with the upper surface plate extension 41, so rainwater is prevented from entering the gap.
