Description

The present invention relates to a roof structure and panel members used therefor.

BACKGROUND ART Honeycomb panels, which are lightweight and have excellent corrosion resistance, are widely used as roofing materials such as roofs and eaves of buildings (see, for example, Patent Document 1). The honeycomb panel includes a frame member obtained by combining hollow frame members made of extruded materials in, for example, a rectangular shape, a core member having a honeycomb structure accommodated inside the frame member, and affixed to the front and back of the frame member and the core member. It consists of a face plate and a

Japanese Patent Application Laid-Open No. 2020-66950

In the case of a roof structure in which the honeycomb panel is inclined in one direction and suspended from a frame, the honeycomb panel is supported by the frame by fastening the frame members to the frame with bolts or the like. Fasteners for fastening the honeycomb panel and the frame are attached to the honeycomb panel after waterproofing. In addition, even if the waterproofness of the mounting part of the fastener deteriorates due to deterioration over time, rainwater that has entered the inside of the frame member from the mounting hole of the fastener is guided to the inside of the frame member in the downward slope, It is designed to be discharged from the drain port.

By the way, in a large roof structure, for example, intermediate aggregates are provided between a plurality of frame members, and a plurality of honeycomb panels are provided between the frame members and the intermediate aggregates. In that case, the honeycomb panel is supported by the frame by bolting the frame to the frame member and the intermediate aggregate. However, the ends of the intermediate aggregates are butted against the side walls of the frame member that forms the outer edge of the panel and are joined by welding or the like. There is a risk that rainwater will not be drained smoothly due to damming at the joint of the outer edge of the panel with the frame member. Therefore, it is possible to machine rainwater drainage holes at the manufacturing site of the roof structure, but this takes time and effort and lowers productivity.

Therefore, the present invention provides a roof structure having an excellent drainage function that can quickly and smoothly drain water that has entered the inside of the middle aggregate without reducing productivity, and can maintain high quality for a long period of time. It aims at providing the panel member used for.

As shown in FIGS. 1 and 2, the roof structure 100 has a panel member 10 and a frame 13 that is a supporting member that fixes the panel member 10 in a suspended state. The frame 13 is formed in an inverted L shape when viewed from the side, and one or more (three are illustrated here) are arranged. In the drawings, the Y direction is the longitudinal direction of the panel member 10, the Z direction is the height direction, and the X direction is the width direction of the panel member 10 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 frame 13 has a beam portion 13b provided with a plurality of mounting brackets 12 at intervals. Fasteners 25 such as bolts provided on the panel member 10 are fastened to these fittings 12 . Thereby, the panel member 10 is suspended from the beam portion 13b of the frame 13 and supported.

The panel member 10 is supported by the beam portions 13b of the frame 13 and is inclined downward from the horizontal plane in the direction extending from the tip of the beam portion 13b to the leg portion 13a. Also, the panel member 10 is provided with a gutter member 30 or a decorative material (not shown) along the edge thereof.

FIG. 3 is a schematic perspective view of the panel member 10 showing the internal structure with a part cut away.
As shown in FIG. 3, the panel member 10 includes a rectangular plate-shaped core member 14, a frame member 17 disposed surrounding the core member 14, and sandwiching the core member 14 and the frame member 17 in the plate thickness direction. and a top plate 21 and a bottom plate 23 that are fixed with.

The core member 14 has a honeycomb structure as a core material, in which walls are erected in a honeycomb shape. That is, the core member 14 has a plurality of cells 14a that are formed in a hollow cylindrical shape that is hexagonal in plan view. The cells 14a are formed to have the same thickness and are connected to each other. As a result, the core member 14 has a honeycomb structure having a plurality of cells 14a, thereby forming a lightweight and highly rigid structure.

The core member 14 is made of metal such as aluminum or an aluminum alloy, for example. The core member 14 made of aluminum is resistant to corrosion and excellent in workability. The core member 14 made of aluminum is manufactured, for example, by laminating a plurality of aluminum plates, fixing a part of the laminated aluminum plates with an adhesive, and stretching them in the lamination direction. Alternatively, the core member 14 may be formed by stretching a plurality of aluminum plates partially connected by extrusion molding. Note that the core member 14 may be molded from a resin such as plastic.

The frame member 17 is a frame having an 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. The frame member 17 is made of, for example, an aluminum or aluminum alloy extruded material, and has a hollow or solid cross section.

The upper plate 21 and the lower plate 23 are attached to the front and back surfaces of the core member 14 and the frame member 17, respectively. The upper plate 21 and the lower plate 23 are made of a plate material such as an acrylic resin plate, an aluminum plate, a steel plate, or a fiber-reinforced plastic plate, and are fixed to the core member 14 and the frame member 17 with an adhesive.

FIG. 4 is a plan view of the panel member 10 showing the internal structure by notching the top plate 21 and the frame member 17 in order.
The frame member 17 has horizontal frame members (first frame members) 31 , vertical frame members (second frame members) 33 , and intermediate aggregates 35 .
The frame member 17 is formed in a rectangular shape by joining both ends of two vertical frame members 33 to the ends of two horizontal frame members 31 arranged parallel to each other by welding or the like so as to intersect each other at right angles. there is Thereby, the internal spaces of the hollow horizontal frame member 31 and the hollow vertical frame member 33 are communicated with each other.

The middle aggregate 35 is provided in the center of the frame formed by the horizontal frame members 31 and the vertical frame members 33 . The middle aggregate 35 is arranged in parallel with the vertical frame member 33, and both ends thereof are abutted against the horizontal frame member 31 and joined to the horizontal frame member 31 by welding or the like. The frame member 17 provided with the intermediate aggregate 35 has two accommodation spaces S defined therein, and the core members 14 are provided in each of these accommodation spaces S. As shown in FIG.

Although the rectangular panel member 10 is shown here as an example, the shape of the panel member 10 is not limited thereto. For example, it may be a polygonal shape such as a triangle, a shape other than a rectangle such as a circle or an ellipse, or a shape in which shapes other than a rectangle are partially combined. In that case, the horizontal frame member 31 and the vertical frame member 33 have a portion that intersects at an angle other than a right angle. That is, the shape of the panel member 10 is arbitrary.

A plurality of through holes 37 through which the fasteners 25 are inserted are formed in the vertical frame member 33 and the intermediate aggregate 35 . The horizontal frame members 31 on the lower side of the inclination (upper side in FIG. 4) are provided with drainage ports 41 between the vertical frame members 33 and the intermediate aggregates 35, respectively. The drain port 41 is provided on the horizontal frame member 31 on the lower side of the panel member 10, but may also be provided on the upper side of the horizontal member 31 in order to obtain symmetry of the panel member 10. FIG.

FIG. 5 is a perspective view of the joint between the horizontal frame member 31 and the intermediate aggregate 35 on the lower side of the inclination.
In FIG. 5, the top plate 21 and the core member 14 are omitted. A side portion of the horizontal frame member 31 is composed of an inner plate portion 31a and an outer plate portion 31b arranged to face each other. The horizontal frame member 31 is composed of a pair of end plate portions 31c arranged facing each other and connecting the upper and lower edges of the inner plate portion 31a and the outer plate portion 31b. The inner plate portion 31a of the horizontal frame member 31 has a smooth outer surface on the housing space S side.

A lower end plate portion 31c, which is the bottom portion of the horizontal frame member 31, is partially cut out in the width direction (X direction) to form a drain port 41. As shown in FIG. The drain port 41 communicates the accommodation space S, the internal space 31s of the horizontal frame member 31, and the outside of the horizontal frame member 31 with each other. That is, the drain port 41 forms a flow path between the accommodation space S and the outside of the horizontal frame member 31 .

The middle aggregate 35 has a pair of side plate portions 35a facing each other, and a pair of end plate portions 35c arranged to face each other by connecting upper and lower edges of the side plate portions 35a. A pair of side plate portions 35a of the intermediate aggregate 35 are arranged to face the housing space S, and the ends thereof are butted against the inner plate portions 31a of the horizontal frame members 31 and joined by welding or the like. A through hole 37 through which the fastener 25 is inserted is formed in the end plate portion 35c arranged on the upper side of the intermediate aggregate 35. As shown in FIG.

In the horizontal frame member 31 shown in FIG. 5, a pair of upper and lower groove portions 45 are continuously formed along the longitudinal direction (Y direction) in the inner plate portion 31a to which the end portion of the intermediate aggregate 35 is joined. . These grooves 45 are provided near the corners formed between the intermediate aggregate 35 and the end plate portions 35c. Of the pair of grooves 45, the lower groove 45 constitutes a water conduit R, the details of which will be described later.

6 to 10 are cross-sectional views in FIG. 4 showing the water conduit of the panel member 10, FIG. 6 is a cross-sectional view along the VI-VI line, FIG. 7 is a cross-sectional view along the VII-VII line, and FIG. FIG. 9 is an enlarged cross-sectional view showing the P portion of 7, FIG. 9 is a cross-sectional view of the lower end in the section taken along line IX--IX, and FIG. 10 is an enlarged cross-sectional view of the lower end taken along line XX.

As shown in FIG. 6, the groove portion 45 is formed above the height of the lower end plate portion 35c of the intermediate aggregate 35 and below the height of the upper end plate portion 35c. That is, even if the horizontal frame member 31 is turned upside down, the groove portion 45 has the same positional relationship as the end plate portion 35c. Therefore, by providing the above-described drain port 41 and through hole 37 at corresponding positions in the vertical direction, there is no need to worry about the direction of the horizontal frame member 31 when assembling the roof structure at the manufacturing site.

As shown in FIG. 7, the end plate portion 35c of the intermediate aggregate 35 is abutted against the inner plate portion 31a of the horizontal frame member 31 and joined thereto. Then, as shown in FIG. 8, at the lower joint between the horizontal frame member 31 having the groove 45 and the intermediate aggregate 35, the height Hu of the upper edge of the groove 45 is the height of the hollow space of the intermediate aggregate 35. It is higher than the bottom surface, that is, the inner surface height position Hn of the lower end plate portion 35c. As a result, the water conduit R communicates with the internal space 35s of the intermediate aggregate 35 . Further, the height position Hd of the lower edge portion of the water conduit R is set to a height equal to or lower than the inner surface height position Hn of the lower end plate portion 35 c of the intermediate aggregate 35 . In this configuration example, the height position Hd of the lower edge of the water conduit R is equal to the inner surface height position Hn of the end plate portion 35c of the intermediate aggregate 35, and the water conduit R and the end plate portion 35c are flush with each other. It's becoming

Further, as shown in the cross section in FIG. 9, between the intermediate aggregate 35 and the drain port 41, the water conduit R similarly communicates with the accommodation space S in which the core member 14 is accommodated. 10, the water conduit R communicates with the drain port 41 at the position where the drain port 41 is formed.

By the way, a portion where the fastener 25 is attached to the panel member 10 is waterproofed to prevent water from entering the inside of the panel member 10 . However, in the roof structure 100 of this configuration, even if water enters the vertical frame member 33 and the intermediate aggregate 35 of the frame member 17 from the through hole 37 through which the fastener 25 is inserted, Equipped with a drainage function that can drain water that has been soaked.

Next, the drainage function of the roof structure 100 will be described in detail.
(Infiltration of water from vertical frame member 33)
As indicated by arrow A in FIG. 4 , the water that has entered the vertical frame member 33 through the through holes 37 flows through the vertical frame member 33 toward the downward slope of the panel member 10 . Further, this water passes through the interior of the horizontal frame member 31 and is discharged from the drain port 41 and sent to the gutter member 30 .

(Infiltrated water from middle aggregate 35)
As shown by arrows B in FIGS. 4 and 5 , the water that has entered the interior of the intermediate aggregate 35 from the through holes 37 of the intermediate aggregate 35 flows downward in the slope and flows through the intermediate aggregate 35 . It abuts against the inner plate portion 31 a of the frame member 31 . Then, as shown in FIG. 5, the water hitting the inner plate portion 31a of the horizontal frame member 31 enters the groove portion 45 formed in the inner plate portion 31a.

As shown in FIG. 8, the groove portion 45 has a height position Hu of the upper edge at the joint with the intermediate aggregate 35, which is higher than an inner surface height position Hn of the end plate portion 35c of the intermediate aggregate 35. The height position Hd of the lower edge portion is equal to or lower than the inner surface height position Hn of the end plate portion 35 c of the intermediate aggregate 35 . Therefore, the water that hits the inner plate portion 31 a of the horizontal frame member 31 smoothly flows into the groove portion 45 without stagnation within the intermediate aggregate 35 .

The water that has entered the groove 45 flows along the longitudinal direction (Y direction) of the horizontal frame member 31 toward the drain port 41 through the water conduit R along the groove 45 . At this time, even during the flow between the intermediate aggregate 35 and the drain port 41, the water in the water conduit R flows forward without being blocked by the core member 14 in the housing space S (see FIG. 9). After that, the water in the water conduit R flows to the water outlet 41 communicating with the water conduit R and is discharged downward from the water outlet 41 (see FIGS. 10 and 5). In addition, since the inner plate portion 31a of the lateral member 31 in which the groove portion 45 is formed has a smooth outer surface on the housing space S side, the inner wall surface of the formed groove portion 45 is smooth. Therefore, the flow resistance of water in the groove portion 45 is lowered, and this also enhances the drainage performance.

As described above, according to the roof structure 100 according to the present embodiment, even if water enters the vertical frame member 33 and the central aggregate 35, the water that has entered is quickly and smoothly discharged from the drain port 41. can. In particular, since the ends of the intermediate aggregates 35 are abutted against the horizontal frame members 31 , the water inside the intermediate aggregates 35 is temporarily blocked, but the water inside the intermediate aggregates 35 is discharged to the drain port 41 . Drainage efficiency can be enhanced by providing the conduit R for guiding. As a result, the water entering the inside of the intermediate aggregate 35 is reliably discharged to the outside, and high quality can be maintained for a long period of time without deteriorating the adhesive for bonding and fixing the upper surface plate 21 and the lower surface plate 23 due to moisture. In addition, it is possible to eliminate the need for processing at the manufacturing site, such as processing the horizontal frame member 31 to form drainage holes, etc., thereby suppressing an increase in installation cost.

In addition, the water conduit is composed of a groove portion 45 continuously formed in the longitudinal direction (Y direction) of the inner plate portion 31a of the horizontal frame member 31 to which the intermediate aggregate 35 is joined. The water inside can smoothly flow to the drain port 41 along the groove portion 45 . Further, when the horizontal frame member 31 is manufactured by extrusion molding, it is only necessary to provide a projection or the like for forming the groove portion 45 in a part of the existing extrusion mold without newly manufacturing an extrusion mold, thereby reducing the manufacturing cost. suppressed.

Further, in the horizontal frame member 31, groove portions 45, which serve as water conduits R, are formed at positions near the corners of the inner plate portion 31a and the end plate portions 35c. Therefore, even if the horizontal frame member 31 is turned upside down at the time of assembly, any of the grooves 45 can be made to function as the water conduit R, and the assembly work will not be complicated.

In the above embodiment, the case where one central aggregate 35 is provided between the vertical frame members 33 is illustrated, but two or more central aggregates 35 may be provided between the vertical frame members 33. . Moreover, the structure which arranged the vertical frame material 33 of multiple pairs may be sufficient.

Further, in the above embodiment, the groove 45 is formed in the inner plate portion 31 a of the horizontal frame member 31 and the groove 45 is used as the water conduit R, but the water conduit R is not limited to the groove 45 .

FIG. 11 is an enlarged cross-sectional view showing a modification of the P portion of FIG.
For example, as shown in FIG. 11, the lower end (corner) of the horizontal frame member 31 to which the middle aggregate 35 of the inner plate portion 31a is joined is formed to be recessed inward, and the longitudinal direction (Y direction) is provided. The recess 47 and the bottom plate 23 constitute the water conduit R. As shown in FIG. Also in this modification, the height position Hu of the upper edge of the water conduit R is set higher than the height position Hn of the inner surface of the end plate 35c of the intermediate aggregate 35, and the height of the lower edge of the water conduit R The height position Hd is set to a height equal to or lower than the height position Hn of the inner surface of the end plate portion 35c of the intermediate aggregate 35 .

That is, the position of the lower edge portion of the water conduit R is the upper surface position of the lower surface plate 23 below the height position Hn of the inner surface of the end plate portion 35 c of the intermediate aggregate 35 .

In the case of this modification, the water inside the intermediate aggregate 35 can be guided to the water conduit R formed by the recess 47 of the horizontal frame member 31 and the lower surface plate 23 and can be smoothly discharged to the drain port 41 . Further, when the horizontal frame member 31 is manufactured by extrusion molding, it is only necessary to provide a protrusion or the like for forming the recess 47 in a part of the existing extrusion mold without newly manufacturing an extrusion mold, thereby reducing the manufacturing cost. suppressed.
