  Hereinafter, embodiments of the invention will be described in detail with reference to the drawings.

  FIG. 3 shows a schematic cross-sectional view of an embodiment of the eaves hanger 5 according to the present invention. FIG. 1 shows an eaves edge structure when the eaves hanger 5 is attached to the eaves. A schematic cross-sectional view of the example is shown. The eaves hanger 5 includes a first attachment part 51 for attachment along the upper surface of the rafter 1 and a suspension part 52 for attaching the eaves eaves 6. The eaves-end structure according to the present embodiment includes a rafter 1, a windbreak member 4 installed in the vertical direction adjacent to the outer surface of the rafter 1, a field plate 2 installed above the rafter 1 and the windbreak member 4, A roofing material 3 installed on the upper side of the field plate 2, an eaves anchor 5, and an eaves anchor 6 are provided. The eaves basket 6 is attached to the hanging portion 52 of the eaves hanging tool 5.

  As described above, the conventional eaves hanger 50 as shown in FIG. 2 is fixed to the outer surface of the blast member 4 installed in the vertical direction using the fixing member 8 such as a screw or a nail. . Since the eaves 6 may be subjected to rain, snow, or wind, the windbreak member 4 may be damaged, or the windbreak member 4 is thin, and the windbreak member 4 is thin and cannot fix the screws or nails. The eaves hanger 50 is easily removed from the member 4.

  On the other hand, the eaves hanger 5 according to the present embodiment has a first mounting portion 51 for mounting along the upper surface of the rafter 1, and the first upper portion of the rafter 1 as shown in FIG. The attaching part 51 can be attached. For this reason, it is possible to fix the eaves hanger 5 to the front of the eaves without being affected by the material and thickness of the windbreak member 4. In addition, the rafter 1 is a structural material that forms the roof skeleton, and a member that is thick enough to support the roof is used. Therefore, the fixing effect of the fixing member 8 such as a screw or a nail is also obtained. high. Further, by providing the first attachment portion 51 of the eaves hanger 5 on the upper surface of the rafter 1, there is an advantage that a fixing force due to gravity can be obtained.

  Therefore, the degree of freedom in design including the material and thickness of the windbreak member 4 is increased. For example, the material of the windbreak member 4 can be made of not only wood but also resin or metal without requiring a thick wooden base. In addition, the thickness of the windbreak member 4 can be set without worrying about the attachment strength of the eaves hanger 5.

  Further, in the eaves tip structure according to this embodiment, the first attachment portion 51 of the eaves hanger 5 is sandwiched between the upper surface of the rafter 1 and the lower surface of the field board 2. Since the first mounting portion 51 is concealed from the outside, it is difficult to receive the force of rain, snow, and wind, which also contributes to preventing the eaves-hanging hanger 5 from falling off. Further, since the influence of rain, snow and wind is reduced, the material of the first mounting portion 51 is also advantageous in that it is difficult to cause rust and deterioration. The first mounting portion 51 of the eaves hanger 5 is sandwiched between the upper surface of the rafter 1 and the lower surface of the field board 2 because the first mounting portion 51 is the upper surface of the rafter 1 and the field board 2. It is a concept including not only the aspect directly pinched in the state which contacted the lower surface of this, but the aspect pinched indirectly through another member.

  Since the first mounting portion 51 of the eaves hanger 5 is sandwiched between the upper surface of the rafter 1 and the lower surface of the field board 2, the first mounting portion 51 of the eaves hanger 5 is used as the upper surface of the rafter 1. It is necessary to install the base plate 2 after that. In order to facilitate the installation work on the rafter 1, the first attachment portion 51 further reduces the influence on the construction work of the field board 2 on the rafter 1. It is preferable to have a flat surface that is in contact with each other, and can typically be a flat plate shape. Moreover, when the thickness of the 1st attachment part 51 is thick, since the clearance gap arises in the rafter 1 and the field board 2 in the part which has not installed the eaves hook suspension 5, the thickness of the 1st attachment part 51 is thinner Is desirable. Specifically, the thickness of the first attachment portion 51 is preferably 5 mm or less, more preferably 1 mm or less, and for example, 0.2 to 5 mm.

  The eaves hanger 5 is preferably made of a material that can support the eaves eaves 6 and that does not easily break even when rain, snow, or wind is applied, and has long-term durability. For example, a metal, polycarbonate, ASA resin, AES resin, etc. are mentioned. The material of the eaves hanger 5 may be changed depending on the part. However, when the first mounting portion 51 of the eaves hanger 5 is thinned, considering the tensile strength with respect to the thickness, at least the first mounting portion 51 is preferably made of metal rather than resin, and further has durability such as rust. It is desirable to use a metal such as stainless steel and galvalume, or a metal whose surface is coated with a rust inhibitor.

  The first attachment portion 51 of the eaves hanger 5 may be linear up to the suspension portion 52, but it is preferable that the first attachment portion 51 be bent in a substantially letter shape in consideration of the construction of the windbreak member 4 and the design properties. And it is more preferable that the eaves hanger 5 further includes a second attachment portion 53 for attachment along the outer side surface of the windbreak member 4. As a result, the eaves hanger 5 can be further fixed along the outer surface of the windbreak member 4, so that the mounting strength of the eaves hanger 5 is improved. Further, the second mounting portion 53 of the eaves hanger 5 may have a flat surface that is in contact with the outer surface of the windbreak member 4 so as to easily withstand the force applied from above the eaves 6 such as snow and snowfall. Preferably, it can typically be substantially flat.

  The eaves hanger 5 may be an integrally molded product. However, as shown in FIG. 1, the base plate 2 and the roofing material 3 are constructed on the first mounting portion 51, so that the first mounting portion 51 can be simplified. Since it cannot be removed, it is desirable that the suspending portion 52 be a separate part that can be detached so that the suspending portion 52 can be easily replaced when there is a problem. The structure of the hanging part 52 is not particularly limited as long as the eaves 6 can be attached, and may be either an inner hanging type or an outer receiving type, but the inner hanging type is preferable from the viewpoint of design.

  FIG. 4 is a schematic view for explaining an embodiment of the eaves hanger 5 to which the suspending portion 52 is detachable. The eaves hanger 5 according to the present embodiment includes a first attachment portion 51 for attachment along the upper surface of the rafter 1, a suspension portion 52 for attachment of the eave cage 6, and a windbreak member installed in the vertical direction. 4 has a second mounting portion 53 for mounting along the outer side surface of 4. The second attachment portion 53 extends from an outer portion 53a connected to the suspension portion 52, an inner portion 53b that can be attached to and detached from the outer portion 53a, and one end of the first attachment portion 51, and is formed by the outer portion 53a and the inner portion 53b. And an insertion portion 53c to be sandwiched.

  Further, the eaves anchor hanging tool 5 according to the present embodiment includes parts that constitute the outer part 53a of the hanging part 52 and the second attachment part, parts that constitute the first attachment part 51 and the insertion part 53c, and a second part. It has three parts which constitute the inner part 53b of the attachment part.

  There is no particular limitation on the structure that allows the outer portion 53a and the inner portion 53b to be detachable. For example, a structure that can be engaged by providing a convex portion on one side and a concave portion on the other side can be adopted. In the present embodiment, the outer portion 53a of the second mounting portion 53 has a rectangular plate 53a1 installed in a positional relationship parallel to the outer surface of the windbreak member 4, and two erected from the left and right edges of the rectangular plate 53a1. An engaging portion 53a3 having a frame structure having a side wall 53a2 and configured by a concave portion (or a convex portion) or the like that can be attached to and detached from the inner side portion 53b is installed on the side wall 53a2. In addition, the inner portion 53b of the second attachment portion 53 corresponds to the inner surface shape of the frame structure of the outer portion 53a and has an outer surface shape that can be accommodated in the frame structure of the outer portion 53a. The engaging portion 53a3 is configured by a concave portion (or convex portion) or the like of the side wall 53a2, and the engaging portion 53b2 is configured by a detachable convex portion (or concave portion) or the like. In contrast to the present embodiment, the inner portion 53b may have a frame structure, and the outer portion 53a may be accommodated in the frame structure of the inner portion 53b.

  In FIG. 4, the hidden portion of the outer portion 53a is indicated by a dotted line. In the present embodiment, the inner surface of the rectangular plate 53a1 of the outer portion 53a has one or more protrusions 53a4 extending toward the inner portion 53b, and faces the inner surface of the rectangular plate 53a1 of the outer portion 53a. The rectangular surface 53b1 of the inner portion 53b that has a recess portion 53b3 that can be fitted to the protrusion portion 53a4 of the outer portion 53a. On the other hand, the flat insertion portion 53c extending from one end of the first attachment portion 51 has a hole 53c1 through which the protrusion 53a4 of the outer portion 53a can be inserted, and the protrusion 53a4 of the outer portion 53a is inserted. The insertion portion 53c is sandwiched and fixed by the outer portion 53a and the inner portion 53b by being inserted into the hole 53c1 of the portion 53c and fitting into the recess portion 53b3 of the inner portion 53b. In contrast to the present embodiment, the portion 53a4 can be a recessed portion and the portion 53b3 can be a protruding portion.

  When the first attachment portion 51 of the eaves hanger 5 is attached to the upper surface of the rafter 1, it is necessary to provide a distance between the rafter 1 and the suspension portion 52 in consideration of the thickness of the windbreak member 4. In providing this distance, it is desirable to provide an index of the attachment position on the first attachment portion 51. As an example of the index of the attachment position, an example in which the scale line 51a is provided in the parts constituting the first attachment portion 51 and the insertion portion 53c of the eaves hanger 5 shown in FIG. An example in which 51b is provided is shown in FIG. FIGS. 5A and 5B are schematic views when the component is observed from the direction of the arrow.

  In the past, when attaching eaves suspensions after construction of breezes, the leveling of the eaves was performed to determine the linearity of the eaves, and the attachment position of the eaves suspension was determined. Thus, the mounting position can be determined without leveling.

  As long as the eaves hanger 5 is attached to the rafter 1 as long as the eaves hanger 5 is an attachment method that does not fall off due to rain, snow or wind, the method is not limited, but the simplest attachment method is nail or FIG. 6 is a schematic view showing a mounting method using screws. The fixing member 7 to the upper surface of the rafter 1 is preferably fixed at two or more points in order to increase the attachment strength. In addition, a nail, a screw, or the like that fixes the eaves anchor 5 is collectively referred to as a fixing member.

  In FIG. 6, the suspending portion 52 is illustrated, but when the suspending portion 52 is detachable, the first mounting portion 51 is attached to the upper surface of the rafter 1 with the suspending portion 52 removed, and then the suspending portion 52 is attached. May be.

  In consideration of the case where the eaves anchor suspension 5 is attached to the upper surface of the rafter 1 using the fixing member 7, as shown in FIGS. 4 and 5, the first attachment portion 51 has a fixing hole for the rafter 1. It is desirable to provide 51c.

  In this way, the construction period can be shortened by attaching the eaves suspension 5 simultaneously with the construction of the rafters 1 before the construction of the field board 2, the roofing material 3, and the windbreak member 4.

  Further, from the viewpoint of increasing the attachment strength of the eaves hanger 5, it is preferable to provide an attachment portion on the outer surface of the windbreak member 4, and in this case, as shown in FIGS. 4 and 5, It is desirable to provide a fixing hole 54 for the windbreak member 4 in the attachment portion 53. FIG. 7 shows that the fixing member 7 and the fixing member 8 are respectively inserted into the first mounting portion 51 disposed along the upper surface of the rafter 1 and the second mounting portion 53 disposed along the outer surface of the windbreak member 4. The example which fixed the eaves-hanging tool 5 to the eaves end is shown. By fixing the eaves hanger 5 to the wind breaker member 4 with the fixing member 8, the strength against the force of the blowing air from below the eaves eaves 6 increases. As with the fixing member 7 on the upper surface of the rafter 1, the fixing by the fixing member 8 to the outer surface of the windbreak member 4 is performed at two or more points if space for attaching the fixing member 8 allows to increase the attachment strength. Fixing is desirable. Furthermore, it is preferable in terms of securing the mounting strength that the fixing member 8 penetrates through the second mounting portion 53 and the windbreak member 4 and the tip is stopped inside the rafter 1.

  In particular, when the hanging part 52 of the eaves hanger 5 has a detachable structure shown in FIG. 4, when the rain, snow or wind force is applied, the engaging parts 53a3 and 53b2 are released. Since there is a possibility that the suspension part 52 may come off, the attachment along the outer surface of the windbreak member 4 of the eaves hanger 5 is performed by the outer part 53a, the insertion part 53c, and the inner part of the eaves hanger 5 It is preferable that the fixing is performed by one or more, preferably two or more fixing members 8 penetrating 53b. In this case, the outer portion 53 a, the insertion portion 53 c, and the inner portion 53 b each have a fixing hole 54 that penetrates to the windbreak member 4.

  The height position of the fixing hole 54 for inserting the fixing member 8 into the windbreak member 4 penetrates the windbreak member 4 when the fixing member 8 is horizontally inserted into the windbreak member 4 and is 10 mm or more in the rafter 1. It is preferable to set the position where the tip can be inserted and stopped inside the rafter 1. When the fixing member 8 is pierced by 10 mm or more into the rafter, the fixing effect of the fixing member is manifested. Therefore, the material and thickness of the windbreak member 4 do not affect the fixing effect.
