Description

TECHNICAL FIELD This disclosure relates to roof structures.

BACKGROUND ART Conventionally, a roof of a building is known in which roof panels are arranged side by side to form a roof (for example, see Patent Document 1). In this prior art, the gap between adjacent roof panels is covered with a plurality of vertical covers lined up along the longitudinal direction of the gap.

Moreover, the vertical covers that are adjacent to each other in the longitudinal direction have their edge portions butted against each other, and a gap is created between the vertical covers due to the design clearance. Therefore, this gap is sealed by filling it with caulking material.

JP2015-28288A

However, in the above-mentioned conventional technology, since there is a gap between the vertical covers, there is a risk of water leakage, and there is a possibility of water leakage depending on the accuracy of the caulking material filling operation. In addition, the caulking material may adhere to adjacent members, resulting in a deterioration in construction quality, and avoiding such adhesion to adjacent members may result in insufficient filling of the caulking material, resulting in water leakage as described above. There was a risk that this could lead to the possibility of

Therefore, an object of the present disclosure is to provide a roof structure that can improve the waterproof performance and construction quality of the connection portion of the vertical cover.

In the roof structure of the present disclosure, a plurality of roof panels formed by spanning a roofing material between a pair of roof frames are arranged in parallel in a direction perpendicular to the extending direction of the roof frames to form a roof, A gap is interposed between the roof frames of adjacent roof panels, and a plurality of vertical covers covering the gap and the pair of roof frames sandwiching the gap are provided in succession along the gap and the roof frames. The vertical cover includes a cover top plate that covers the gap and the pair of roof frames sandwiching the gap from above, and a cover top plate that extends downward from both widthwise sides of the cover top plate to cover the pair of roof frames. It is a roof structure that includes a cover side plate that covers from the sides.

In order to achieve the above object, the ends of the vertical covers are vertically overlapped at the joints of the adjacent vertical covers, and the ends disposed on the lower side of the vertical covers are A roof structure is provided in which a slit is formed at the corner of the cover top plate and the cover side plate along the corner from the edge of the vertical cover, and the inside of the slit is filled with caulking material.

In the roof structure of the present disclosure, since the cover top plate and the cover side plate that sandwich the slit can be relatively displaced at the ends arranged on the lower side, even if the ends of the vertical cover have the same dimensions, The ends of the cover can be stacked one on top of the other.

In this way, since the ends of the vertical cover are stacked one on top of the other, there is no gap in the longitudinal direction of the vertical cover unlike in a structure in which the ends of the vertical cover are butted against each other, and the waterproof performance can be improved. Furthermore, since the slit is filled with caulking material from the inside, water leakage from the slit can be prevented. Furthermore, since the caulking material is filled from the inside into the slit covered from above at the end of the vertical cover, it is possible to avoid adhesion to adjacent members and improve construction quality. .

Returning to FIG. 1, the building unit H1 has four steel columns H11, . It includes a frame member formed in the shape of a rectangular parallelepiped frame with steel beams (H12, H13, etc.).

Note that the horizontally extending beam spanned between the upper ends of the columns H11 and H11 is a ceiling beam on the lower floor, and a roof beam on the top floor. Here, the roof beam on the long side (girder side) is defined as the girder roof beam H12, and the roof beam on the short side is defined as the gable roof beam H13. Although FIG. 1 shows only the skeleton of the building unit H1, the building unit H1 includes walls, floors, ceilings, etc. that are not shown.

As shown in FIGS. 1 and 2, on the upper side of the unit building H, a plurality of roof panels 10 each having a vertically elongated rectangular shape are arranged in parallel across a plurality of building units H1 to form a roof LF. .

Here, the long side of the roof panel 10 has a length that projects from the girder side end of the unit building H, as shown in FIG. A plurality of these roof panels 10 ("7" in the first embodiment) are arranged in parallel in the direction along the girder roof beam H12 of the building unit H1 to form the roof LF. Note that the relationship between the length of the roof panel 10 and the number of building units H1, . . . to be spanned can be arbitrarily set. Further, the roof LF is provided with a long eave portion H3 that largely extends from the building unit H1.

The roof panel 10 includes a pair of roof frames 2, 2 and a roofing material 4, as shown in FIG. The roofing material 4 is installed so as to straddle a pair of roof frames 2, 2 that are arranged substantially parallel to each other and to close the space between them.

A guide portion 3 having a pair of supporting members 31, 31 and a shedding board 32 as a base board is provided inside the pair of roof frames 2, 2. The support material 31 is made of a wooden crosspiece or the like, and is attached to the inside of the roof frames 2, 2 in accordance with the water gradient formed on the upper surface of the roofing material 4. By placing both side edges of the shedding board 32 on the pair of supporting materials 31, 31, the same slope as the slope of the supporting materials 31, 31 is formed on the upper surface of the shedding board 32. Note that the upper surface of the roof board 32 is covered with a waterproof sheet such as polyethylene roofing.

The roofing material 4 is installed on the waterproof sheet of the shedding board 32, and the roofing material 4 is made of, for example, a hot-dip aluminized steel plate having excellent waterproof performance and corrosion resistance.

Furthermore, the solar cell module 1 is provided on the roof panel 10 so as to straddle the roof frames 2, 2 and to be spaced apart upwardly from the upper surface of the roofing material 4.

Receiving metal fittings 11A, 11B are provided on both side edges of the solar cell module 1, and the receiving metal fittings 11A, 11B are fixed to the roof frames 2, 2.

These receiving metal fittings 11A and 11B have different heights, and the solar cell module 1 is attached to the roof frame 2 at an angle.

In addition, as shown in FIG. 1, the roof panel 10 is assembled to the girder roof beam H12 by fastening bolts 21b and nuts 21c that are inserted into the roof frame 2 and passed through holes provided in the girder roof beam H12. is fixed.

As shown in FIG. 4, a plurality of vertical covers 5 are provided between the roof panels 10, 10 along the extending direction of the roof panels 10.

That is, as shown in FIG. 5, a gap SP is provided between the roof frames 2, 2 of the roof panels 10, 10 installed next to each other. This gap SP and the pair of roof frames 2, 2 are covered by a vertical cover 5.

(Vertical cover and its fixing structure)
Next, the vertical cover 5 and its fixing structure will be explained.
As shown in FIGS. 4 and 5, the vertical cover 5 includes a cover top plate 51 and a pair of cover side plates 52, 52 hanging down from both ends of the cover top plate 51 in the width direction.

The vertical cover 5 is installed so that the upper plate is placed over the roof frames 2, 2 of the adjacent building units H1, H1 forming the gap SP, and the side plates are placed along the sides of the roof frames 2, 2. has been done. Moreover, a waterproof tape 53 is adhered to the back surface of the upper plate, and this waterproof tape 53 is adhered to the upper surface of the roof frames 2, 2.

Further, the vertical cover 5 is fixed to a vertical cover fixing fitting 6 fixed to the roof frame 2. As shown in FIG. 6, this vertical cover fixing fitting 6 is installed in the longitudinal direction of the roof frame 2 at a position where a gap 11s is provided between the solar cell modules 1.

As shown in FIG. 7, this vertical cover fixing metal fitting 6 includes a metal fitting top plate 61 and a metal fitting side plate 62. A fixing convex portion 63 is formed on the metal fitting upper plate 61 and is continuously formed above the metal fitting side plate 62 in an upwardly convex shape. Furthermore, a pair of screw insertion holes 65a and 65b shown in FIG. 6 are formed in the plane portion of the upper metal fitting plate 61, through which drill screws 64 for fixing to the roof frame 2 are inserted.

As shown in FIGS. 7 and 8, the vertical cover fixing fittings 6 are made by inserting drill screws 64 into the screw insertion holes 65a, 65b and the roof frame 2 with the fitting upper plate 61 in contact with the upper surface of the roof frame 2. It is fixed to the roof frame 2 by passing through it.

Note that, as shown in FIG. 6, one screw insertion hole 65a is formed in a round hole shape, and the other screw insertion hole 65b is formed in an elongated hole shape. The elongated screw insertion holes 65b are used to fix the pair of vertical cover fixing fittings 6, 6 with the drill screws 24 when there is a misalignment (dimension Ga) in the extending direction of the roof frame 2 at the mounting positions. This is to make it possible to adjust the mounting position by loosening it.

The vertical cover 5 is fixed to the roof frame 2 by being fixed to the vertical cover fixing fittings 6 fixed to the roof frame 2 as described above.
That is, as shown in FIGS. 7 and 8, the vertical cover fixing fittings 6 are fixed from the cover side plate 52 of the vertical cover 5 installed from above over the adjacent roof frames 2, 2 of the adjacent building units H1. By passing a drill screw 65 through the convex portion 63 and screwing it in, the intermediate portion of the vertical cover 5 is fixed to the vertical cover fixing fitting 6. Note that, as will be described later, both ends 54a and 54b of the vertical cover 5 in the longitudinal direction are fixed to the roof frame 2 with drill screws 201 or the like.

The work of screwing in the drill screws 65 for fixing the intermediate portion of the vertical cover 5 to the vertical cover fixing fitting 6 is performed using a tool 70 from the gap 11s between the solar cell modules 1. Further, when screwing in the drill screw 65, a guide hole 66 (see FIG. 8) is formed in advance from the cover side plate 52 of the vertical cover 5 to the fixing convex portion 63 through the same.

Furthermore, when screwing in the drill screw 65, caulking material 67 such as silicone material is applied to the outer periphery of the drill screw 65, and the drill screw 65, the cover side plate 52 of the vertical cover 5, and the fixing convex are tightened. A caulking material 67 is filled between the parts 63 and 63. Note that FIG. 7 shows a container 67c filled with caulking material 67. Further, after the drill screw 65 is fastened, it is preferable to mark the drill screw 65 to indicate that it has been fastened. This prevents forgetting to drive the drill screw 65.

(Vertical cover joint structure)
The total length of the vertical cover 5 is shorter than the total length of the roof panel 10, and since a plurality of vertical covers 5 are arranged in series in the longitudinal direction, as shown in FIG. A joint SM occurs between the two.

Below, the structure of the joint SM between the vertical covers 5, 5 will be explained.
The vertical cover 5 includes an end 54a on the water side and an end 54b on the water bottom side. At the joint SM, an end 54b on the water side of the vertical cover 5(A) placed on the water side is placed on top of the water side end 54a of the vertical cover 5(U) placed on the water side. It is installed with a cover. In addition, in the description of the vertical cover 5, when distinguishing between above water and below water, the code (A) is attached to the above water side, and the code (U) is attached to the below water side. Moreover, when there is no distinction between above water and below water, it is simply written as vertical cover 5.

As shown in FIGS. 9 and 10, a slit 55 is formed in the water-side end 54a of the vertical cover 5 at a corner between the cover top plate 51 and the cover side plates 52, 52 along the longitudinal direction. has been done.

Then, the lower end 54b of the vertical cover 5 on the upper water side is vertically overlapped with the upper end 54a of the vertical cover 5 on the lower water side by a dimension longer than the length of the slit 55. There is.

Here, since a slit 55 is formed in the water-side end 54a of the vertical cover 5, the cover top plate 51 and cover side plate 52 sandwiching the slit 55 can be relatively displaced and deformed in a direction to reduce the outer circumferential dimension. It becomes. Therefore, even if the above-water side end 54a and the below-water side end 54b of the vertical cover 5 have the same cross-sectional shape, the end 54b can be overlapped from above the end 54a as described above. . Note that the number of vertical covers 5 required to cover the entire length of this gap SP is arbitrary and may be plural.

(Water stop structure and construction procedure for vertical cover joints)
Next, the waterproof structure of the joint SM between the vertical covers 5, 5 will be explained together with the construction procedure.
When installing the vertical cover 5, a waterproof tape 53 is first adhered to the back surface of the cover top plate 51 of the vertical cover 5 before installation. Note that, when installing the vertical cover 5, the waterproof tape 53 comes into contact with the upper surfaces of the roof frames 2, 2, and seals the gap SP.

When installing the vertical cover 5, install it in order from the underwater side as described above. When installing the vertical cover 5 (U) on the underwater side, at the joint SM, apply caulking to cover the inner surface of the slit 55 at the edge 54a on the underwater side, as shown in FIG. Fill 101. Note that in FIG. 9, illustration of the waterproof tape 53 is omitted.

Then, the vertical cover 5 is installed on the pair of roof frames 2, 2, and fixed with drill screws 65 to the vertical cover fixing fittings 6 fixed to the roof frame 2 as described above (see FIGS. 7 and 8). ). Note that, although not shown, the end 54b on the underwater side of the vertical cover 5 disposed furthest under the water is aligned with the end of the roof frame 2, and then screwed with a drill screw (not shown). Fix it to the roof frame 2.

Next, a caulking material 102 is applied around the edge of the above-water side end 54b of the cover top plate 51 of the vertical cover 5(U) on the below-water side installed as shown in FIG. At this time, a pressing force F1 indicated by an arrow is applied to the cover side plate 52 of the vertical cover 5 (U) to make the outer circumferential dimension smaller than the original dimension.

Next, as shown in FIG. 12, caulking material 103 is applied to the cover top plate 51 and the inner surface of the corner of the end 54b on the underwater side of the vertical cover 5(A) that is installed continuously on the water side. .

Then, as shown in FIG. 10, the end 54b on the water side of the vertical cover 5 on the water side is placed over the end 54a on the water side of the vertical cover 5 on the water side. As a result, the vertical covers 5(U) and 5(A) are in a state in which the upper cover plates 51 are stacked vertically and the cover side plates 52 are stacked horizontally, as shown in FIG.

Next, as shown in FIG. 10, drill screws 201 are screwed in from above the cover upper plates 51 that are stacked one above the other. Note that the position where this drill screw 201 is screwed in is a position below the water than the application position of the caulking material 102 shown in FIG. 11.

Furthermore, as shown in FIG. 14, the tip edge of the cover upper plate 51 on the underwater side of the vertical cover 5 (A) on the underwater side and the cover upper plate 51 of the vertical cover 5 (U) on the underwater side are straddled. At the same time, a caulking material 105 is also applied on the head of the drill screw 201 (not shown in FIG. 14).

Then, waterproof tape 202 is pasted on the cover upper plates 51, 51 of both vertical covers 5(U), 5(A), including the area where this caulking material 104 is applied and the area where the drill screw 201 is screwed. .

Furthermore, as shown in FIG. 15, caulking is applied to both sides of the water-above side and the water-below side of the waterproof tape 202 on the cover upper plates 51, 51 of both vertical covers 5(U), 5(A), respectively. Two strips of material 105 are applied in the width direction.

Next, the connection cover member 80 is placed over the joint SM of both vertical covers 5(U) and 5(A).
The connection cover member 80 is a member having a length of about 30 cm and formed into a U-shaped cross section by a joint upper plate 81 and joint side plates 82, 82. When installing the connection cover member 80, first, as shown in FIG. . Then, the connection cover member 80 is placed over the joint SM. At this time, the longitudinal center position of the connection cover member 80 is aligned with the position of the drill screw 201.

(Effects of Embodiment 1)
The effects of the first embodiment are listed below.
(1) In the roof structure of the first embodiment, a roof panel 10 formed by spanning a roofing material 4 between a pair of roof frames 2, 2 is arranged in a direction perpendicular to the extending direction of the roof frame 2. A roof LF is formed by arranging a plurality of them in parallel. Further, a gap SP is interposed between the roof frames 2, 2 of the adjacent roof panels 10, 10, and the vertical cover 5 covering the gap SP and the pair of roof frames 2, 2 sandwiching the gap SP is arranged to cover the gap SP and the roof frames 2, 2. A plurality of vertical covers 5 are provided continuously along the frames 2, 2, and include a cover top plate 51 that covers the gap SP and the pair of roof frames 2, 2 sandwiching the gap SP from above, and a cover top plate 51 that covers the width direction of the cover top plate 51. This roof structure includes cover side plates 52, 52 that extend downward from both sides and cover the pair of roof frames 2, 2 from the sides.

Further, at the joint SM between adjacent vertical covers 5, the ends 54a and 54b of the vertical covers 5 are vertically overlapped. A slit 55 is formed in the end portion 54a disposed on the lower side of the vertical cover 5 at the corner portion of the cover upper plate 51 and the cover side plates 52, 52 from the edge of the vertical cover 5 along the corner portion. The roof structure is such that the inside of the slit 55 is filled with caulking material 101.

Therefore, at the end portion 54a of the vertical cover 5 disposed on the lower side, the cover upper plate 51 and the cover side plate 52 that sandwich the slit 55 can be relatively displaced, so that the end portions 54a and 54b have the same dimensions. You can also stack the two on top of each other. In this way, since the ends 54a and 54b of the vertical cover 5 are overlapped vertically, there is no gap in the longitudinal direction of the vertical cover 5 unlike in the structure where the edges of the vertical cover 5 are butted against each other, and waterproofing is achieved. Performance can be improved. Further, since the slit 55 is filled with caulking material 101 from the inside, water leakage from the slit 55 can be prevented. Since the caulking material 101 is filled from the inside into the slit 55 covered from above by the end 54b of the vertical cover 5, adhesion to adjacent members can be avoided and construction quality can be improved. can be achieved.

(2) In the roof structure of the first embodiment, the roofing material 4 is provided with a water gradient in the direction along the roof frame 2. At the joint SM of the vertical cover 5, the vertical cover 5(A) placed on the water side is placed on the water side end 54a of the vertical cover 5(U) placed on the water side of the water slope. The ends 54b on the underwater side are overlapped.

In this way, since the above-water side end 54a of the below-water side vertical cover 5(U) and the below-water side end 54b of the above-water side vertical cover 5(A) are overlapped vertically, both ends 54a , 54b, and water resistance can be further improved.

(3) In the roof structure of the first embodiment, caulking materials 102 and 103 as sealing members are interposed between the ends 54a54b of the vertical covers 5 and 5 at the joint SM between the adjacent vertical covers 5 and 5. ing.
Therefore, the waterproofness between the ends 54a54b can be further improved.

Furthermore, in the first embodiment, the caulking materials 102 and 103 are provided in parallel at two locations in the longitudinal direction of the vertical cover 5, and the drill screw 201 is screwed in between. Therefore, waterproofness can be ensured even in a structure in which the vertical covers 5, 5 are fixed by passing the drill screws 201 through the ends 54a, 54b.

(4) In the roof structure of the first embodiment, the tip edge of the end portion 54b located on the upper side of the joint SM is covered with the caulking material 104 and the waterproof tape 202 as an edge sealing member.
Therefore, it is possible to reliably prevent water from entering through the gap between the tip edge of the end portion 54b and the end portion 54a, thereby further improving waterproof performance.

In addition, in the first embodiment, since the drill screw 201 that fixes the ends 54a and 54b is covered with the caulking material 105 and the waterproof tape 202, water intrusion from the penetrating portion of the drill screw 201 is more reliably prevented. The waterproof performance can be further improved.

(5) In the roof structure of Embodiment 1, the portion where the ends 54a and 54b of the joint SM are overlapped is the joint side plate 82 that covers the cover side plate 52 and the joint upper plate 81 that covers the cover upper plate 51. It is covered by a connection cover member 80 having a.

Therefore, water leakage from the joint SM due to deterioration of the caulking materials 104 to 106, the waterproof tape 202, etc. can be more reliably prevented.

Furthermore, since the caulking material 106 and the caulking material 107 are filled between the connection cover member 80 and the ends 54a and 54b of the vertical cover 5, water does not flow from the connection cover 80 to the joint SM between the ends 54a and 54b. It is possible to prevent the infiltration of water and further improve waterproof performance.

Although the embodiment of the roof structure of the present disclosure has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes can be made without departing from the gist of the present invention. are included in the present invention.

For example, in the embodiment, an example is shown in which the solar cell module 1 is provided on the roof panel 10, but a shielding material other than the solar cell module 1 may be provided, or no shielding material such as the solar cell module 1 is provided. It may also be a structure.

In addition, in the embodiment, at the joint SM, the water of the vertical cover 5 (A) placed on the water side is placed on the water side end 54a of the vertical cover 5 (U) placed on the water side. Although the example in which the lower end portions 54b are overlapped is shown, the present invention is not limited thereto. In particular, in this embodiment, as a flat roof type roof, the roofing material 4 has a water slope, but the roof frame 2 does not have a roof slope. It is also possible to place the end 54a of the vertical cover 5 on top. Note that the roof frame 2 may also have a roof slope, and in this case, as shown in Embodiment 1, it is preferable to overlap the vertical covers 5 on the water side with the ends 54b facing upward.

In the embodiment, the caulking materials 102 and 103 are provided as the sealing materials, and are provided on both the water side and the water bottom side at the position where the drill screw 201 is screwed.
