  The sagging prevention material 15 is an extruded member having higher rigidity than the closing material 14 and having the width direction of the roof 12 as the extrusion direction. As shown in FIG. 4, the sagging prevention material 15 is sufficiently shorter than the width of the roof 12 and the closing material 14, and a plurality of the dripping prevention materials 15 are provided at appropriate intervals in the width direction of the roof 12.

  Each sag prevention member 15 is provided with a sag prevention member abutting on the outer wall 2a side of the upper projecting portion 16f across the upper projecting portion 16f forming the end of the roof 12 on the outer wall 2a side together with the closing member abutting portion 14a. It has a contact portion 15a and a support portion 15b that is connected to the sag prevention material contact portion 15a and extends toward the outer wall 2a and supports the closing material extension portion 14b from below.

  The support portion 15b is inclined so as to become higher toward the outer wall 2a side in the attached state of the sag prevention material 5 in which the sag prevention material contact portion 15a is in contact with the upper projection portion 16f. The blocking material abutting portion 14a is in contact with the lower surface of the closing material extending portion 14b of the closing material 14 in contact with the anti-outer wall side of 16f.

  A plurality of (two in this embodiment) grooves, so-called notches, are provided at appropriate intervals in the extending direction extending from the sagging prevention material contact portion 15a, that is, in the direction toward the outer wall 2a. 15c is formed along the outer wall 2a. The site | part in which the notch 15c is provided is equivalent to the weak part 15d weaker than the other site | part of the said support part 15b in the support part 15b. For this reason, the sag prevention member 15 can fold off the portion on the distal end side in the extending direction at the fragile portion 15d, and the extension of the support portion 15b from the sag prevention member contact portion 15a by the fold off. It is possible to adjust the output L1.

  The sag prevention member 15 is provided with a projection 15e in which the support portion 15b protrudes on the opposite side of the sag prevention member contact portion 15a, that is, on the side opposite to the outer wall. The protrusion 15e engages and closes the edge 16g of the upper protruding portion 16f of the outer wall side frame member 16 when the sag prevention member abutting portion 15a is brought into contact with the upper protruding portion 16f from the outer wall 2a side. The material 14 enters the groove 14c. Here, the protrusion 15 e of the sag preventing member 15 corresponds to an engaging portion that engages with the edge 16 g of the outer wall side frame member 16.

  The closing material 14 and the sag prevention material 15 of the present embodiment are applied to the sag prevention material 15 while engaging the protrusion 15e of the sag prevention material 15 from the outer wall 2a side of the outer wall side frame material 16 with the edge 16g of the outer wall side frame material 16. The contact portion 15a is brought into contact with the upper projecting portion 16f, and the plugging material 14 is inserted into the groove 14c from the side opposite to the outer wall side of the outer wall side frame member 16 while the projection 15 and the edge portion 16g are inserted. The screw 3 that is brought into contact with the protruding portion 16f and penetrates the blocking material contacting portion 14a and the upper protruding portion 16f from the side opposite to the outer wall is screwed into the drooping prevention material contacting portion 15a to be fixed to the outer wall side frame member 16. At this time, since the protrusion 15e is engaged with the edge 16g of the outer wall side frame member 16, the droop prevention member 15 is rotated together with the screw 3 by the rotation of the screw 3. Never do. For this reason, when attaching the blocking material 14 and the sag prevention material 15, the outer wall side frame material 16 can be securely attached to the blocking material 14 and the sag prevention material 15 by simply tightening the screw 3 from the side opposite to the outer wall without pressing the sag prevention material 15. It is possible to fix to.

  When attaching the closing material 14 and the sag prevention material 15 to the outer wall side frame material 16, when the roof unit 1 is constructed, the tip of the sag prevention material 15 and the outer wall 2a are spaced apart from each other by a larger distance than the predetermined distance. In addition, in the extending direction, the extension L1 of the support portion 15b is adjusted in advance by breaking off the portion on the tip side from any of the weak portions 15d. Here, the predetermined distance between the tip of the sag prevention member 15 and the outer wall 2a is the maximum amount of displacement of the roof 12 toward the outer wall, which is assumed when the roof unit 1 after construction is shaken by wind or the like. is there.

  According to the roof unit 1 of the present embodiment, since the closing material 14 that closes the space between the outer wall 2a of the building 2 and the roof 12 has flexibility, the roof unit 1 provided independently of the building 2 is provided. Even if the gap between the roof 12 and the outer wall 2a changes due to wind or the like, the closing material 14 bends, so that the outer wall 2a is not damaged, and the gap between the roof 12 and the outer wall 2a is blocked by the closing material 14. Can be maintained.

  Moreover, since the sag prevention material 15 which prevents the sagging material 14 having flexibility and is more rigid than the sieving material 14 has the sag prevention material 15, it is assumed that rainwater accumulates or snow accumulates on the sieving material 14. However, it is possible to prevent the closure material 14 from dripping and leaking rainwater, or snow falling under the roof 12.

  Further, the closing material 14 is brought into contact with the upper projecting portion 16f which is the end of the roof 12 on the outer wall 2a side, and the anti-sagging material 15 contacts the upper projecting portion 16f with the closing material contacting portion 14a. In order to attach the closing material 14 to the roof 12, the screw 3 entering the portion 15 a from the closing material contact portion 14 a side is fastened to the roof 12 by being fastened to the sag preventing material 15 having higher rigidity than the closing material 14. It is possible to securely attach the closing material 14 and the sag prevention material 15 to the roof 12 without providing a separate dedicated member.

  The sag prevention material 15 having higher rigidity than the closing material 14 is damaged by contact with the outer wall 2a when the roof unit 1 is shaken if an appropriate distance L2 is not secured with respect to the outer wall 2a of the building 2. There is a risk of doing. For this reason, according to the roof unit 1 of the present embodiment, the support portion 15b of the sag prevention material 15 that supports the closing material extension portion 14b extending to the outer wall 2a side from the bottom is the sag prevention material contact portion. Since the fragile portion 15d has a notch 15c and is more fragile than other parts at a position where the amount of extension from 15a differs, as shown in FIG. It is possible to adjust the space | interval of the dripping prevention material 15 and the outer wall 2a of the building 2 by excising the site | part of the front end side from 15c.

  Moreover, since the dripping prevention material 15 has the protrusion 15e as an engaging part engaged with the edge part 16g along the roof 12 provided in the upper protrusion part 16f by the side of the outer wall 2a of the roof 12, it is a plugging material. Even when the screw 14 is fixed by the screw 3 screwed to the anti-sagging material contact portion 15a, the rotation of the anti-sagging material 15 accompanying the tightening of the screw 3 is restricted. For this reason, it is possible to provide the roof unit 1 excellent in workability.

  In this embodiment, in order to adjust the space | interval of the dripping prevention material 15 and the outer wall 2a of the building 2, the example provided with the weak part 15d which has the notch 15c in the support part 15b of the dripping prevention material 15 was demonstrated. This is not a limitation. For example, as shown in FIG. 6, it is good also as a structure which divided | segmented the dripping prevention material 15 into two members. In this case, with respect to the sag prevention contact member 17 and the sag prevention contact member 17 which fix the sag prevention material contact part 17b from the outer wall 2a side of the outer wall side frame member 16 in contact with the upper projecting part 16f. And a slide member 18 as a support member that is provided so as to be slidable in the extending direction and can be fixed to the sag prevention contact member 17. The slide member 18 is provided with a long hole along the extending direction, and the slide member 18 is slid in the extending direction with respect to the sag preventing contact member 17, whereby the slide member 18 of the sag preventing member 15 and the outer wall 2 a It is possible to finely adjust the interval L2.

  At this time, when the distance between the tip of the sag prevention member 15 and the outer wall 2a is narrow, the closing member 14 is supported only by the sag prevention contact member 17 as shown in FIG. In this way, by making the structure in which the sag prevention member 15 is divided into two members, it is possible to further increase the adjustment allowance for the interval between the sag prevention member 15 and the outer wall 2a.

  Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
