Next, the soot leakage countermeasures implemented in the predetermined slope lower end section in the eaves ridge direction will be described.
FIG. 7 is a diagram explaining the soot leakage.
When snow is accumulated in a cold region with a lot of snow, warm air from indoors produces snowmelt water on the upper surface of the folded plate 15 and the inner upper surface of the gable 16 in the girder direction. On the other hand, the outer edge in the gable direction, the lower edge in the eaves ridge direction, and the edge of the eaves of the gable 16 are exposed to the wind, so melted snow water is likely to freeze and form ice embankments and icicles. When the ice embankment is formed in this way, snowmelt water stays on the upper surface of the folded plate 15 and the upper surface of the gable 16 inside in the girder direction. The accumulated snowmelt water intrudes into the gable receiving cover 17 through the gap between the gable receiving cover 17 and the gable upper plate portion 51 of the gable 16, and crosses the gable receiving hardware 13 to cause soot leakage.

FIG. 8 is a diagram showing a roof structure for countermeasures against soot leakage.
The gable 16 has a gable standing plate portion 53 .
The gable standing plate portion 53 extends downward from the outer end portion of the gable upper plate portion 51 in the girder direction, with the eaves ridge direction and the vertical direction being the plane directions.
In the predetermined slope lower end section in the eaves ridge direction, the cover clip 18 is omitted, and the gable direction outer end of the gable receiving cover 17 is extended outward in the girder direction along the gable upper plate portion 51, In addition, it is fixed to the outer surface of the gable standing plate portion 53 in the girder direction. Specifically, the gable cover 17 includes a first extension 71 and a second extension 72 .

The first extension part 71 is provided along the upper surface of the gable upper plate part 51 with the eaves ridge direction and the girder direction as the plane direction, and the outer and inner sides of the eaves ridge direction upper end in the girder direction are A round hole (not shown) is formed through each of them in the thickness direction. The lock rivets 25 are inserted into these round holes, and the first extension portion 71 is fixed to the gable upper plate portion 51 by crimping the lock rivets 25 .
The second extension part 72 extends downward from the girder direction outer end of the first extension part 71 with the eaves ridge direction and the vertical direction as the plane direction, and the girder standing plate part 53 has a girder direction outer surface are set along. Round holes (not shown) penetrating in the thickness direction are formed in the second extension portion 72 at predetermined intervals along the eaves ridge direction. The lock rivets 25 are inserted into these round holes, and the lock rivets 25 are crimped to fix the second extension portion 72 to the gable standing plate portion 53 .

FIG. 9 is a perspective view of the roof structure.
In the drawing, the gable cover 17 is hatched with dots. Between the first extension portion 71 and the gable upper plate portion 51 and between the second extension portion 72 and the gable standing plate portion 53, predetermined areas are filled with a sealing material and a caulking agent. In the drawing, the areas to be filled with the sealing material and the caulking agent are hatched. The sealing material is processed into a tape shape and is used by sticking it to the construction part. The caulking agent is in the form of a paste and is applied to the work area using a caulking gun. The sealing material is affixed so as to overlap the round hole, and is penetrated by a lock rivet 25. - 特許庁In FIG. 8, only the tape-shaped sealing material 78 is shown for convenience.

The area to be filled with the sealing material and the caulking agent is the entire circumference of the inner end 73 in the girder direction of the first extension 71 between the first extension 71 and the gable upper plate portion 51 . Further, the entire circumference of the outer end 74 in the girder direction of the first extension 71 and the entire circumference of the upper end 75 in the eaves ridge direction of the first extension 71 . Furthermore, between the second extension portion 72 and the gable standing plate portion 53, the entire circumference of the lower end portion 76 of the second extension portion 72 and the entire eaves ridge direction upper end portion 77 of the second extension portion 72 is around.
FIG. 10 is an enlarged view of the joint portion.
Here, the state where the portion A in FIG. 9 is viewed from above in the eaves ridge direction is shown. Of the gable cover 17, a sealing material and a caulking agent are filled and closed at the upper end in the eaves direction of the section on the lower end side of the gradient and on the inside of the first extension 71 in the girder direction. Only the caulking agent 79 is illustrated here for convenience.

However, as a countermeasure against leakage, the gable cover 17 is provided with the first extension 71 and the second extension 72 only in the slope lower end section.
FIG. 11 is a diagram explaining the setting of the slope lower end section.
(a) in the figure is a diagram explaining the length L in the eaves ridge direction in the slope lower end section. The slope lower end section depends on the roof slope θ, the height d of the gable bracket 13, and the maximum assumed depth H when snowmelt water stays on the upper surface of the gable 16 and the upper surface of the folded plate 15 due to the ice embankment. A slope lower end section is set. The slope lower end section is set as the length L from the lower end in the eaves ridge direction according to the following formula. The maximum assumed depth H is an empirical value.
L={H×√(1+tan ² θ)−d}×(1/tan θ)

(b) in the figure is a table showing the length L of the section on the lower end side of the gradient. The height d of the gable bracket 13 is, for example, 0.037 m. The maximum assumed depth H of snowmelt water is a value based on empirical values, and is, for example, in the range of 0.10 to 0.15 m. The roof slope θ is, for example, in the range of 1/10 to 1/50. According to this embodiment, when the roof slope θ is 1/50 and the maximum assumed depth H of snowmelt water is 0.14 to 0.15 m, the length L of the slope lower end section exceeds 5 m, Other than that, the length L of the slope lower end side section is less than 5 m. Since the roof slope θ is generally greater than 1/50 in a snowy cold region, it can be seen that the length L of the slope lower end section of 5 m is sufficient. Therefore, the slope lower end section is set in a range of 5 m from the lower end in the eaves ridge direction.

《Effect》
Next, main effects of one embodiment will be described.
The folded plate 15 thermally expands and contracts in the longitudinal direction due to temperature changes. A gable 16 is provided on the gable side of the roof, and since the gable 16 is fixed to the wall, it absorbs the thermal expansion and contraction of the folded plate 15 between the gable 16 and the folded plate 15 at the end of the girder direction. measures are required.
Therefore, the roof structure 11 includes a Z-clip 12 , a gable bracket 13 , a seam tab 14 , a folded plate 15 , a gable cover 16 and a gable cover 17 . According to this, the folded plate 15 is fixed to the seam tab 14 which can advance and retreat in the direction of the eaves ridge, and the gable 16 is fixed to the gable bracket 13 . Therefore, when the folded plate 15 thermally expands and contracts, the seam tab 14 follows, and the advance and retraction of the seam tab 14 can absorb the thermal expansion and contraction of the folded plate 15 between the folded plate 15 and the gable 16 .

Specifically, the Z clip 12 is formed to have a substantially "Z" shape when viewed from above in the eaves ridge direction, and the folded plate receiving upper plate portion 33 has an elongated hole 35 along the eaves ridge direction. is formed. The gable receiving hardware 13 is formed to have a substantially “C” shape when viewed from above in the direction of the eaves ridge, and the upper end of the gable 16 is fixed to the gable receiving standing plate portion 37 . The seam tab 14 is formed to have a substantially inverted "T" shape when viewed from the upper side in the eaves ridge direction, is inserted into the elongated hole 35, and is clamped above the folded plate receiving upper plate portion 33. A portion 43 protrudes. Both the girder-direction outer end of the folded plate 15 and the girder-direction inner end of the gable receiving cover 17 are tightened with respect to the seam portion 43 . As a result, the seam tab 14 can be allowed to advance and retreat, and thermal expansion and contraction of the folded plate 15 can be absorbed between the folded plate 15 and the gable 16 .

The roof structure 11 also comprises cover clips 18 . The cover clip 18 is formed to have a left-right reversed substantially “L” shape when viewed from above in the eaves ridge direction, and includes a clip lower plate portion 56 . The lower surface side of the clip lower plate portion 56 is hooked to the outer edge of the gable cover 17 in the row direction. The gable receiving cover 17 is fixed to the seam tab 14 together with the folded plate 15 at its inner end in the girder direction, but the outer end in the girder direction is hooked to the cover clip 18 so as to be able to move forward and backward in the eaves ridge direction. be done. As a result, when the folded plate 15 thermally expands and contracts, the seam tab 14 and the gable cover 17 follow. It can absorb expansion and contraction.

In a cold region with a lot of snow, snowmelt water may accumulate on the upper surface of the folded plate 15 and the inner upper surface of the gable 16 in the girder direction due to the ice embankment. Over 13 could have caused a leak.
Therefore, in the predetermined slope lower end section, the cover clip 18 is omitted, and the gable direction outer end of the gable receiving cover 17 is extended outward in the girder direction along the gable upper plate portion 51, and It is fixed to the outer surface of the gable standing plate portion 53 in the girder direction. As a result, it is possible to prevent snowmelt water from entering the gable receiving cover 17 and leaking over the gable receiving hardware 13. - 特許庁In addition, since countermeasures against sill leakage are not performed in the entire eaves ridge direction, an increase in cost can be suppressed. In the slope lower end side section, the seam tab 14 is restricted from advancing and retreating by fixing the gable cover 17 to the gable 16, but the thermal expansion and contraction of the folded plate 15 is prevented above the slope lower end side section in the eaves ridge direction. can be absorbed.

Specifically, the gable cover 17 includes a first extension 71 and a second extension 72 . The first extension portion 71 is provided along the upper surface of the gable upper plate portion 51 and is fixed to the gable upper plate portion 51 . The second extension portion 72 is provided along the outer surface of the gable standing plate portion 53 in the girder direction and is fixed to the gable standing plate portion 53 . As a result, leakage of dust can be prevented without degrading the design.
Between the first extension portion 71 and the gable upper plate portion 51 and between the second extension portion 72 and the gable standing plate portion 53, predetermined areas are filled with a sealing material and a caulking agent. Specifically, between the first extension portion 71 and the gable upper plate portion 51, the entire circumference of the inner end portion 73 in the girder direction of the first extension portion 71, and the outer side of the girder direction of the first extension portion 71 and the entire periphery of the end 75 of the first extension 71 on the upper side in the eaves ridge direction. Furthermore, between the second extension portion 72 and the gable standing plate portion 53, the entire circumference of the lower end portion 76 of the second extension portion 72 and the entire eaves ridge direction upper end portion 77 of the second extension portion 72 is around. As a result, it is possible to effectively prevent snowmelt water from entering the gable cover 17 through the fixed portion by the lock rivet 25 and the joint portion on the upper side in the eaves ridge direction.

Further, of the gable cover 17, a sealing material and a caulking agent are filled and closed at the upper end in the eaves ridge direction of the section on the lower end side of the gradient and on the inside of the first extension 71 in the girder direction. As a result, it is possible to effectively prevent snowmelt water from entering the gable receiving cover 17 from the joint portion on the upper side in the eaves ridge direction.
In addition, in the slope lower end section, the eaves A length L from the lower end in the ridge direction is set. This makes it possible to easily and accurately determine the length L required to prevent soot leakage.

Specifically, the slope lower end section is set to have a length L of 5 m from the lower end in the eaves ridge direction. This will prevent soot leakage in most buildings in cold, snowy areas. If the length exceeds 5 m, a special bending machine is required. Therefore, an increase in cost can be suppressed. In addition, in the slope lower end side section, the gable cover 17 is fixed to the gable 16 to restrict the advance and retreat of the seam tab 14, but if the slope lower end side section is 5 m or less, the slope lower end side section The thermal expansion and contraction of the folded plate 15 can be sufficiently absorbed above.
