In the present invention, the joint material is installed between the anchor rising pieces of the coupling member so that the interval between the anchor rising pieces is increased.
For this reason, even if the space between the joints between the face materials is widened, by securing the anchor upright piece, the engagement margin between the anchor engaging piece and the face material engaging portion is secured, It is possible to reliably engage the coupling member and the face material.
In addition, the joint material is installed on the coupling member even after the anchor rising piece is expanded. Therefore, after construction, for example, even if an external force acts in a direction to disengage the anchor engaging piece and the face material engaging portion due to strong winds, etc., the joint material restricts deformation that reduces the distance between the anchor rising pieces. The engagement strength can be kept high.

Further, in the case where the joint material is formed in a wedge shape in which the side surface in contact with the anchor upright piece is inclined downward, the degree of expansion of the anchor upright piece can be adjusted according to the degree of downward pressing of the joint material with respect to the coupling member. . Thereby, the engagement margin of the anchor engaging piece of a coupling member and the face material engaging part of a face material can be adjusted.
In addition, the cover part of the joint cover member formed in a curved shape bulging upward that can promote elastic deformation in the expanding direction of the cover side piece is compared with the cover part formed in a flat shape that does not curve. And the elastic deformation margin which expands a cover side piece becomes large.
Therefore, even if the spacing between the face material rising pieces is widened due to the expansion of the joint material or the width dimension of the joint part, the cover side piece can be opened widely, and the joint cover member can be easily attached, improving workability. Excellent.
In the case where the joint material is fixed to the roof material together with the connecting member, the joint material is fixed to the joint portion of the roof material together with the connecting member even after the anchor stand-up piece is expanded. Even if an external force acts in the direction to disengage the anchor engaging piece and the face material engaging portion due to strong winds, etc., the deformation that narrows the distance between the anchor rising pieces is restricted by the joint material, and the engagement strength is increased. Can hold. In addition, since the joint material is fixed to the roof material by the fixing member even after the construction, the fixing strength of the face material is further improved.

Moreover, in the 1st construction method of this invention, even if the space | interval of the joint part between face materials is wide as mentioned above, an anchor engagement piece and a face material are expanded by pushing and spreading an anchor stand-up piece. It is possible to provide a roof structure that secures an engagement margin with the engaging portion and enables the coupling member and the face material to be reliably engaged with each other.
In addition, as described above, the joint material is installed on the coupling member even after the anchor rising piece is expanded. Therefore, after the construction, for example, the engagement between the anchor engaging piece and the face material engaging portion is caused by a strong wind or the like. Even if an external force is applied in the direction of disengagement, the joint material can restrict the deformation that narrows the interval between the anchor rising pieces, and the engagement strength can be kept high.

  Further, even in the second construction method of the present invention, the anchor engaging piece and the face material can be obtained by expanding the anchor rising piece even if the joint portion interval between the face materials is wide as described above. It is possible to provide a roof structure that ensures an engagement margin with the engaging portion and enables the coupling member and the face material to be reliably engaged.

Further, even in the third construction method of the present invention, even if the space between the joints between the face materials is wide as described above, the anchor engaging piece is expanded by expanding the anchor rising piece. It is possible to provide a roof structure that secures an engagement allowance between the face member engaging portion and the joint member and the face member with certainty.
Moreover, since the joint material is fixed to the joint portion of the roof material together with the coupling member even after the anchor rising piece is expanded as described above, after the construction, for example, the anchor engaging piece and the face material are generated by a strong wind or the like. Even if an external force is applied in a direction in which the engagement with the engagement portion is released, the deformation that narrows the interval between the anchor rising pieces is restricted by the joint material, and the engagement strength can be kept high. In addition, since the joint material is fixed to the roof material by the fixing member even after the construction, the fixing strength of the face material is further improved.

A face material engaging portion 11b that is concave in the width direction and opens toward the joint portion 20 described later is formed on the outer side of 11a.

  As shown in FIG. 2, the face material 10 is opposed to the adjacent face material 10 and the face material rising pieces 11 with a space therebetween, and the joint portion 20 is formed between the face material rising pieces 11 and 11. Is formed. In addition, the joint part 20 is arrange | positioned in the position which overlaps with the rafter 32 in the up-down direction.

  The coupling member 40 is formed of a metal plate such as a stainless steel plate having a thickness of about 0.4 mm, an aluminum-plated steel plate, or a vinyl chloride resin-coated copper plate, like the face material 10, and has a hat cross-sectional shape. That is, as shown in FIG. 1, in the coupling member 40, the anchor upright pieces 41 and 41 are raised substantially at right angles from both ends in the width direction of the flat bottom plate portion 40a abutted against the roof material 30. An anchor engaging piece 41a is formed by bending the anchor upright piece 41 outward and obliquely downward from the upper end.

  Then, in a state where the coupling member 40 is fixed to the roof material 30, the anchor engaging pieces 41 a and 41 a are respectively inserted into the face material engaging portions 11 b of the face material rising pieces 11 of the face material 10, and the vertical direction The face material 10 is fixed to the roof material 30 by being engaged with each other.

Next, the waterproof structure of the joint part 20 will be described.
For this waterproofing, a joint cover member 50 and a waterproof material 60 are provided.
The joint cover member 50 covers a fixed portion of the face material 10 by the connecting member 40 from above and from the side. Similar to the face material 10 and the connecting member 40, a stainless steel plate or an aluminized steel plate having a plate thickness of about 0.4 mm. Further, it is formed of a metal plate such as a vinyl chloride resin-coated copper plate.

  As shown in FIG. 2, the joint cover member 50 is formed in a substantially Ω cross-sectional shape opened at the bottom, and as shown in FIG. 4, a cover portion 51 that covers the coupling member 40 and the like from above, and this cover Cover side pieces 52, 52 that extend downward from both ends in the width direction of the part 51 and cover the sides of the face material rising pieces 11, 11 are provided.

The cover portion 51 is formed in an upwardly convex curved shape, and this portion is formed with a larger elastic deformation margin that widens the distance between the cover side pieces 52, 52 than that of a planar shape.
The cover side piece 52 is protruded inward in the width direction and is disposed below the face material protrusion 11a of the face material rising piece 11 of the face material 10, and the face material protrusion 11a is arranged in the vertical direction. A cover engaging portion 52a is formed to engage with the cover.

  As shown in FIG. 3, the waterproof material 60 is configured by laminating a foam 61 such as EPDN (ethylene-propylene-diene rubber) and an adhesive material 62 such as butyl rubber. The foam 61 and the adhesive 62 are brought into contact with the inner surface of the joint cover member 50 when the waterproof material 60 is attached to the joint cover member 50. The width of the adhesive material 62 of the waterproof material 60 is narrower than the width of the foam 61.

Furthermore, as shown in FIG. 3, a concave constricted portion 63 is formed over the entire length of the foam 61 at the center in the width direction of the upper and lower surfaces of the foam 61 of the waterproof material 60.
As shown in FIG. 1, the constricted portion 63 is bent in half so that the waterproof material 60 is inserted into the joint cover member 50, with the waterproof material 60 directed downward at the constricted portion 63. It is possible. Therefore, the waterproof material 60 can be easily inserted into the joint cover member 50.

Further, as shown in FIG. 1, a joint material 70 is inserted between the anchor rising pieces 41, 41 of the coupling member 40.
The joint material 70 is made of a hard resin (for example, vinyl chloride, ABS resin, polyethylene, or the like) or a synthetic rubber (EPDM (ethylene propylene rubber), silicon rubber, or the like). The joint material 70 is formed in a wedge cross-sectional shape in which the side surface 71 is inclined obliquely downward and the width of the upper surface 73 is wider than the width of the lower surface 72 as shown in the figure. And the width | variety of the upper surface 73 is formed more widely than the width | variety of the baseplate part 40a of the coupling member 40, and an anchor standing piece is so pushed that this joint material 70 is pushed into between the anchor standing pieces 41 and 41 of the coupling member 40. 41 and 41 are formed so that the space | interval of 41 may spread. In addition, although illustration is abbreviate | omitted, the joint material 70 has the length equivalent to the connection member 40 in a longitudinal direction.

Next, the construction method of the roof structure according to the first embodiment will be described in order.
(Surface material laying process)
First, the face material 10 is laid on the roof material 30 at a predetermined interval. Thereby, the joint part 20 is formed between the face materials 10. At this time, the joint portion 20 is disposed at a position overlapping the rafter 32.

(Face material fixing process)
Next, the face material 10 is fixed to the roof material 30 using the coupling member 40.
In this case, the coupling member 40 is inserted between the face material rising pieces 11, 11 of the joint portion 20, and the bottom plate portion 40 a of the coupling member 40 is fixed to the roof material 30 with the screws 42.
As shown in FIG. 1, the interval between the face material rising pieces 11 in the joint portion 20 is narrower than the interval between the tips of the anchor engaging pieces 41 a of the coupling member 40. Therefore, when the coupling member 40 is inserted between the face material rising pieces 11, 11, the anchor engaging pieces 41 a, 41 a are made to be elastically deformed so as to reduce the interval between the anchor rising pieces 41, 41. The upper end portions 11c and 11c of the material standup pieces 11 and 11 are passed through without being caught. Thereafter, when the anchor rising pieces 41, 41 are restored, as shown in FIG. 4, each anchor engaging piece 41a is inserted into the face material engaging portion 11b of the face material rising piece 11, and the anchor engaging piece 41a is inserted. And the face material engaging portion 11b are engaged in the vertical direction.

(Bonding member widening process)
The coupling member widening step is performed in order to make the engagement between the anchor engaging piece 41a and the face member engaging portion 11b more reliable in the face member fixing step.
In the connecting member widening step, there is a possibility that the width dimension of the joint portions 20 to be formed may vary, and there may be a portion where the interval between the joint portions 20 is wide depending on the location. In this case, there is a possibility that the engagement allowance between the anchor engaging piece 41a of the coupling member 40 and the face material engaging portion 11b of the face material 10 cannot be secured sufficiently. Therefore, this step is performed at a place where the interval between the face material rising pieces 11 is increased.
Alternatively, even after the construction, in order to ensure the engagement between the anchor engaging piece 41a of the coupling member and the face material engaging portion 11b of the face material 10, this process is performed on all joint portions 20.

In this connecting member widening step, the joint material 70 is inserted between the anchor upright pieces 41 and 41 from above the connecting member 40 as shown by the arrows in FIG. Deformation (either elastic deformation or plastic deformation) that presses in the direction and expands the interval is generated, and the engagement margin between the anchor engagement piece 41a and the face material engagement portion 11b is expanded.
At this time, the distance between the anchor upright pieces 41 and 41 can be adjusted according to the downward pressing amount of the joint material 70 with respect to the coupling member 40.

(Joint cover member installation process)
The joint cover member attaching step is a step of covering the portion of the joint portion 20 where the face material 10 is fixed by the coupling member 40 with the joint cover member 50.
In the joint cover member attaching step, first, the waterproof material 60 is attached to the joint cover member 50. In this case, the waterproof material 60 is bent at the constricted portion 63 and passed between the cover side pieces 52 and 52 in a state of being elastically deformed so as to reduce the dimension in the width direction. Then, when the waterproof material 60 is restored, the waterproof material 60 has a curved shape along the cover portion 51 as shown in FIG. It is mounted without dropping from the member 50.

Thereafter, the joint cover member 50 is placed over the coupling member 40 and the face material rising pieces 11, 11 as shown by the arrows in FIG.
At this time, since the interval between the cover engaging portions 52a and 52a is narrower than the interval between the face material protruding portions 11a and 11a of the face material rising pieces 11 and 11, the interval between the cover side pieces 52 and 52 is set to be smaller. Cover with elastic deformation to expand. Furthermore, when the joint material 40 is pushed into the coupling member 40 and the distance between the anchor engaging pieces 41a and 41a is increased, or due to variation in installation dimensions, the distance between the face material rising pieces 11 and 11 is increased, The joint cover member 50 needs to be elastically deformed so that the distance between the cover-side pieces 52, 52 can be further increased.
In the first embodiment, since the cover portion 51 is formed in a curved shape that swells upward, an elastic deformation margin that widens the space between the cover-side pieces 52 and 52 compared to the case where this portion is formed in a flat shape. Is getting bigger.
Therefore, even when the space between the face material rising pieces 11 and 11 is increased as described above, the joint cover member 50 can be easily elastically deformed and the deformation allowance can be increased, and the workability is excellent.

  In the mounted state of the joint cover member 50 that has completed the above steps, as shown in FIG. 4, the waterproof material 60 is disposed between the cover portion 51 of the joint cover member 50 and the upper end portions of the face material rising pieces 11 and 11. It is interposed in a compressed state and seals between both 52 and 11.

(Effect of Embodiment 1)
In the roof structure of the first embodiment described above, the effects listed below can be obtained.
a) A joint material 70 is provided between the anchor upright pieces 41 and 41 of the coupling member 40 to widen the distance between the anchor upright pieces 41 and 41, and the anchor engaging piece 41a and the face material engaging portion 11b are provided. Increased engagement allowance.
For this reason, even if the space | interval of the face material 10 in the joint part 20 becomes wide by the construction error etc., the anchor engaging piece 41a of the coupling member 40 and the face material engaging part 11b of the face material 10 are ensured. The engagement allowance can be secured. Thereby, the stable fixed intensity | strength of the face material 10 is securable.

b) The joint material 70 is formed in a wedge shape in which the side surfaces 71, 71 in contact with the anchor rising pieces 41, 41 increase the distance between the anchor rising pieces 41, 41 as the joint material 70 is pushed downward.
Therefore, the degree of expansion of the anchor rising pieces 41 and 41 can be adjusted according to the degree of downward pressing of the joint material 70 with respect to the coupling member 40.
Thereby, the engagement margin of the anchor engaging piece 41a of the coupling member 40 and the face member engaging portion 11b of the face member 10 can be adjusted.
Further, when forming the joint material 70 in a wedge shape, the width dimension of the lower surface 72 is slightly shorter than the width dimension of the bottom plate portion 40a of the coupling member 40, and even if the joint material 70 is pushed down to the bottom, It is preferable that the rising pieces 41, 41 are not bent. Moreover, it is preferable that the width dimension of the upper surface 73 is the maximum dimension within a range where the anchor rising pieces 41 and 41 do not expand beyond the maximum required dimension.

c) The cover portion 51 of the joint cover member 50 is formed in a curved shape that swells upward so as to promote the expansion elastic deformation of the cover side pieces 52, 52.
Therefore, the elastic deformation allowance for expanding the cover side pieces 52 and 52 is larger than that formed in a flat shape that does not curve the cover part, and due to the expansion by the joint material 70 and the error of the width dimension of the joint part 20, Even if the interval between the face material rising pieces 11 and 11 is widened, the cover side pieces 52 and 52 are opened wide, so that the joint cover member 50 can be easily attached and the workability is excellent.

  d) The joint material 70 is left installed in the joint member 40 even after the joint material 70 is deformed to expand the anchor rising pieces 41, 41 of the joint member 40. Therefore, after the construction, for example, even if an external force acts in a direction to disengage the anchor engaging piece 41a and the face material engaging portion 11b due to strong wind or the like, the distance between the anchor rising pieces 41 and 41 is reduced. It is regulated by the joint material 70 and the engagement strength can be kept high.

(Embodiment 2)
Next, the roof structure of Embodiment 2 of the present invention will be described.
The roof structure of the second embodiment is different from the first embodiment in the shape of the joint material.
As shown in FIG. 5, the joint material 270 includes a hard portion 273 and a soft portion 274.
The hard portion 273 is formed of a hard resin similarly to the joint material 70 used in the first embodiment. On the other hand, the soft portion 274 is formed of a soft material such as resin or rubber.

  The hard part 273 has inclined side surfaces 271 and 271 for pushing and spreading the anchor rising pieces 41 and 41 of the coupling member 40. Further, as shown in FIG. 6, flanges 273f and 273f for pushing down the upper end portion of the face material rising piece 11 at the time of construction are formed on the upper portions of the side surfaces 271 and 271 so as to protrude in the width direction.

  Therefore, in the second embodiment, when the space between the anchor rising pieces 41, 41 is increased by the joint material 270 in the connecting member widening step, the upper end portion 11c of the face material rising piece 11 is simultaneously shown in FIG. Is pushed downward by the flanges 273f and 273f, the anchor engaging piece 41a is sandwiched between the face material engaging portion 11b and the upper end portion 11c of the face material rising piece 11, and the face material rising piece 11 is The engaged state is maintained more firmly.

Therefore, the fixing strength of the face material 10 by the connecting member 40 after construction is improved. In addition, when the joint material 270 is pushed into the coupling member 40, the joint material 270 is prevented from being inclined to the left and right by the flanges 273 f and 27 f, and the anchor rising pieces 41 and 41 can be evenly widened on the left and right.
Moreover, since the soft part 274 is provided, the impact input to the roof material 30 side when the joint material 70 is attached to the bottom plate part 40a of the coupling member 40 can be reduced.

(Embodiments 3 to 5)
Embodiments 3 to 5 are modifications of the joint material.
A joint material 370 used in the third embodiment shown in FIG. 7 is a modification of the joint material 270 used in the second embodiment, and is an example in which the soft portion 274 is omitted.
That is, the joint material 370 has inclined side surfaces 371, 371 for expanding the anchor rising pieces 41, 41 of the coupling member 40, and a flange for pressing down the upper end portion 11c of the face material rising pieces 11 during construction. 373f and 373f.
Therefore, even in the third embodiment, the same operational effects as those of the second embodiment can be obtained except for the operational effects obtained by the soft portion 274 of the second embodiment.

A joint material 470 used in the fourth embodiment shown in FIG. 8 is a modification of the joint material 70 used in the first embodiment, and is an example in which a hollow portion 472 is formed therein.
