  The eaves member 2 preferably has a structure in which, for example, a polyvinyl chloride resin or a polyvinyl chloride resin layer is covered with a light-resistant resin layer such as AES resin or ASA resin having excellent weather resistance. Molded by a molding method.

  As materials of the first to third core materials 3A, 3B, 3C, for example, fiber reinforced resin (FRP) may be used as long as it has high weather resistance and higher rigidity than the synthetic resin forming the flange member 2. However, it is preferable to use a metal, and in this embodiment, stainless steel is used.

Next, the construction method of the eaves bowl 1 of this embodiment, and the effect | action and function of the eaves bowl 1 are demonstrated.
First, as shown in FIG. 5, before installation of the eaves eaves 1, the eaves member 2 is cut according to the extending dimension of the eaves underside R (see FIG. 1). And it folds according to the shape of the hole 18 of the 3rd hollow wall part W3 formed in the hole 15a of the base end side of the upper protruding item | line 7A of the front ear | edge part 6A, the hole 17 of the back | inner ear part 6B, and the level | step-difference part 27. The bent first to third core members 3A, 3B, 3C are inserted into the holes 15a, 17, 18 corresponding to the shapes.
In this way, the eaves 1 is completed, and the eaves 1 is locked to the eaves support provided in the building to complete the installation of the eaves 1 on the eaves R.

  The eaves bowl 1 installed as described above has a configuration in which the first to third core members 3A, 3B, and 3C can be disposed after the eaves member 2 is cut. The eaves member 2 matched to the dimension of the eaves edge R can be easily cut at the construction site, and the work efficiency of construction can be improved.

  In addition, if the first to third core members 3A, 3B, and 3C are arranged on substantially the entire heel member 2, the ridge member 2 can be prevented from being deformed such as meandering and bending. The first to third core members 3A, 3B, 3C are formed in advance shorter than the installation length of the eaves member 2, thereby cutting the first to third core members 3A, 3B, 3C at the site. The effect that work can be omitted is obtained.

  Furthermore, by cutting the first to third core members 3A, 3B, 3C in advance as described above, the first core member 3A, the third core member 3B, and the third core member 3C can be packed together with the eaves member 2 and are necessary for installing the eaves eaves 1 Can be efficiently transported to the construction site without leakage.

  In addition, the eaves 1 includes holes 15a, 17 and 17 formed in the third hollow wall portion W3 located in the front ear portion 6A, the rear ear portion 6B, and the corner portion 26 that are part of the heel member 2, that is, the upper end. Since the first to third core members 3A, 3B, and 3C are disposed in 18, the strength of the entire eaves 1 can be improved while keeping the eaves 1 as light as possible. Therefore, construction becomes easier and it is possible to effectively prevent the eaves bowl 1 from being deformed or meandering after construction.

  The first to third core members 3A, 3B, and 3C are longitudinal cores that extend in a substantially vertical direction so that a long flat plate member made of stainless steel is brought into contact with the inner surfaces of the holes 15a, 17, and 18. 21e, 22e, 23e and first horizontal cores 21f, 22f, 23f and second horizontal cores 21g, 22g, 23g extending in the same direction from the upper and lower ends thereof (that is, the cross section is substantially U-shaped). It is formed by bending. Therefore, it is possible to prevent the occurrence of rust caused by rainwater and reinforce the eaves member 2 over a long period of time. There is an effect that the strength against deformation such as meandering and bending in a plurality of directions along the plate surfaces of the cores 21g, 22g, and 23g can be increased.

  Further, the first to third core members 3A, 3B, 3C are fitted so as to be in contact with three consecutive inner wall surfaces adjacent to each other in the front ear portion 6A, the rear ear portion 6B, and the hollow wall portion W3. Since it is inserted, the wall portions forming the front ear portion 6A, the rear ear portion 6B, and the third hollow wall portion W3 are firmly supported in the holes 15a, 17, and 18, and meandering in the direction along each surface Thus, it is possible to effectively prevent deformation such as bending.

  In addition, the front ear portion 6A and the rear ear portion 6B, which are the upper ends of the flange member 2, and the first to third hollow wall portions W1, W2, and W3 formed at the corners on the side that is easily exposed to sunlight, are a total of three locations. Since the first to third core members 3A, 3B, 3C are inserted, the eaves rod 1 can be given higher rigidity. Therefore, it can suppress more reliably that the eaves member 2 meanders and deform | transforms at the time of field installation.

  As mentioned above, although embodiment of the eaves bowl 1 of this invention was described, this invention is not limited to the structure shown by the said embodiment, It can change in the range which does not deviate from the meaning of this invention. Specifically, the first to third core members 3A, 3B, 3C are formed in all the holes 15a, 17, 18 of the first to third hollow wall portions W1, W2, W3 formed in the flange member 2. It is not always necessary to be fitted in, for example, to prevent deformation such as meandering even if it is inserted into some hollow wall portions such as the first or second hollow wall portions W1 and W2. The effect of being able to do is obtained. Further, the first to third core members 3A, 3B, 3C may be disposed in hollow wall portions other than the first to third hollow wall portions W1, W2, W3.

  Any or all of the first to third core members 3A, 3B, 3C are arranged across the eaves 2 and 2 connected in one direction with the ends facing each other. Is preferred. That is, as shown in FIG. 6, the first to third core members 3A, 3B, 3C arranged in the hollow wall portions W1-W3 of one eave ridge 2 protrude from the end portions of the eave ridge 2, The core materials 3A, 3B, 3C thus fitted are inserted into hollow wall portions W1-W3 formed at the end portions of the other eaves ridges 2 connected to the one eave ridge 2 via an unillustrated eaves ridge joint. It is preferable that

  In this way, when the first to third core members 3A, 3B, 3C are inserted between one eave ridge 2 and the other eave ridge 2, the ends of the eave ridges 2, 2 It is possible to ensure the strength between the parts (that is, the connecting part) and to ensure the linearity of the eaves 2 and 2.

  Any or all of the first to third core materials 3A, 3B, 3C are preferably arranged over the entire eaves 2 but as long as they do not affect the meandering of the eaves 2. Further, it may be intermittently arranged in the extending direction of the eaves bowl 2.

  In addition, the hollow wall portions W1, W2, and W3 are easy to be formed at the upper end or corner portion 26 of the flange member 2 and are preferable for improving the strength of the flange member 2. It may be formed in the same manner as the ear portion 6A, the rear ear portion 6B, or the hollow wall portion W3 of the corner portion 26, and the core material 3A or the like may be disposed therein.

Moreover, although it is preferable that core material 3A etc. are formed so that it may contact | abut to the inner wall surface of hollow wall part W1, W2, W3, there may be a part which does not contact | abut to an inner wall surface. Furthermore, the core material 3A and the like are substantially U-shaped, that is, the vertical cores 21e, 22e, 23e and the vertical cores 21e, 22e, 23e so as to contact the inner wall surfaces of the adjacent hollow wall portions W1, W2, W3. It is preferably formed in a shape extending in substantially the same direction from both ends in the short direction, but formed so as to contact one or two of the inner wall surfaces of the first to third hollow wall portions W1, W2, W3. It may be what was done.
Further, the surface of the core material 3A or the like has no resistance when inserted with respect to the inner peripheral surface of the abutting hollow wall W1-W3, but becomes a resistance when a force is applied in the pulling direction (not shown). A protrusion may be provided.
