  However, in the above prior art, with the passage of time, a large pressure acts on the side surface of the wooden beam against which the rear surface of the flange abuts due to the load of the roofing material or the veranda member hanging on the arm, and the side surface of the beam It is easy to promote sinking and thinning of the wood, and the lower part of the flange, which is heavily loaded, inclines in the direction of the wooden beam. As a result, the tip of the roofing material such as firewood supported by the arm hangs down, and the building looks bad In addition, there are problems such as structural instability.

  In order to solve such problems, a stiffener is provided between the lower part of the support hardware that supports and fixes the base of the arm and the frame structure such as a pillar of the building to disperse the load applied to the flange of the support hardware. Therefore, measures are taken to prevent indentation and thinning of trees. However, when the stiffener is provided, it interferes with the outer wall, so that it is necessary to form an opening through which the stiffener is passed through the outer wall, and there is a problem that the work is troublesome. Furthermore, there is a problem that a sealing process is required to close the gap between the opening and the stiffener in order to improve the appearance.

  Therefore, the present invention has been made for the purpose of solving the above-described problems and making it possible to adjust the hanging of roof members such as fences over the years, and to maintain the appearance of the building at all times. Is.

  According to this invention, the drooping restraint brace structure of the present invention has an indoor side surface of the mounting plate of the arm main body having a mounting plate to which the arm is fixed on the outdoor side surface, which is in contact with the outdoor side surface of the wooden eaves. The arm main body is configured such that the outdoor side surface of the backing plate of the backing member having a backing plate provided with an overhang adjustment tool capable of moving the pressing member in contact with the outdoor direction comes into contact with the indoor surface side of the wooden eaves beam And the backing member are clamped and fixed by a clamp fixing member with the wooden eaves sandwiched therebetween.

  The overhang adjustment tool is characterized in that the backing plate is provided with a female screw portion that is screwed with a male screw portion formed on the pressing member.

  Further, the tightening fixing member includes a through hole formed in the mounting plate and the backing plate and a bolt inserted into a through hole provided in the wooden eaves beam, and the backing plate of the bolt. The nut is to be screwed into the protruding thread portion.

  Furthermore, a reinforcing material is provided on the indoor side surface of the backing plate.

  The drooping restraint arm bracket is in contact with an outdoor side surface of a wooden eaves beam, an arm body having an arm plate fixed to the outdoor side surface of the mounting plate, and an indoor side surface of the wooden eaves beam The backing plate, a backing member provided with an overhang adjustment tool that allows the pressing member that contacts the indoor side surface of the mounting plate to be moved in the outdoor direction, the arm main body and the backing member are attached to the wooden eaves board. And a fastening member that is fastened by clamping. In addition, the overhang adjustment tool has an internal thread portion that engages with an external thread portion formed on the pressing member on the backing plate, and an engaging portion that can rotate the pressing member at a position protruding from the backing plate. It is to be provided. Further, the tightening fixing member includes a through hole formed in the mounting plate and the backing plate and a bolt inserted into a through hole provided in the wooden eaves beam, and the backing plate of the bolt. The nut is to be screwed into the protruding thread portion. Furthermore, a reinforcing material is provided on the indoor side surface of the backing plate.

  According to the armrest restraining brace structure of the present invention, the load of the corrugation, which is also the roofing material on the armrest, is often applied under the outdoor side of the wooden eaves from the mounting plate. Since dents and thinning of trees occur downward, the pressing member abuts below the indoor side surface of the mounting plate and the load acting on the lower side of the mounting plate is received by the pressing member. It is possible to prevent intrusion and thinning of the tree from occurring due to the load being concentrated and not being applied downward. As a result, the drooping of the heel supported by the arms can be suppressed, the loss of the appearance of the building can be prevented, and the durability of the wooden eaves can be improved. Moreover, when the drooping of the heel further occurs with the passage of time, it can be easily adjusted with the overhang adjustment tool. In addition, since there is no protrusion such as a support material from the outdoor side surface of the wooden eaves beam, it is only necessary to provide a hole through which the arm tree passes on the outer wall, so that the construction is simple. Furthermore, not only in a newly built building, but also in the reinforcement construction of a hanging dredge, this drooping restraint brace structure can be adopted. As a result, it is possible to reinforce the wooden eaves beam that has already been dented or thinned.

  The load acting on the pressing member of the overhang adjusting tool acts to move the backing plate to the indoor side, but the arm main body and the backing member are clamped with the wooden eaves in between. Since the load applied by being fixed by the fixing member acts on both side surfaces of the wooden eaves beam from the entire area of the backing plate and the mounting plate, only the lower part of the outdoor side surface of the wooden eaves beam is recessed. You won't be able to thin the trees. When a load is applied to the backing plate via the pressing member, a force to the indoor side acts below the backing plate, so that the force is distributed over the entire backing plate on the indoor side surface of the backing plate. It is desirable to provide the reinforcing plate so as to act. Then, when the angle of drooping of the heel starts to become anxious, it is only necessary to rotate the pressing member so that the pressing member is applied to the indoor side surface of the mounting plate and protrudes to the outdoor side.

  Further, as the fastening fixing member, a bolt is inserted through a through hole of the wooden eaves beam into a through hole provided in the mounting plate of the arm main body and the backing plate of the backing member, and the backing plate If a nut is screwed into the threaded portion of the bolt projecting from the bolt and fastened, the mounting is simple and can be reliably fixed. Conversely, the thread portion of the bolt may protrude from the mounting plate and be fastened and fixed with a nut.

  The above-described drooping-suppressing arm bracket is a fitting used for the above-described drooping-suppressing brace structure. By changing the area and shape of the mounting plate and the backing plate according to the size of the wooden eaves, the load of a roofing material such as a fence on the arm, etc., it is possible to cope with various arm structures. . In addition, by using the heel drooping suppression metal fitting, as described above, it is possible to prevent the mounting plate from being sunk into the wooden eaves beam and to thin the wood, and to improve the durability of the wooden eaves beam. Furthermore, the above-described drooping restraint brace can be used not only in a newly-built building but also in the case of construction for newly replacing a dredged fence. And since the inclination degree of a ridge can be freely adjusted with an overhang adjustment tool, the appearance of the whole building can always be improved.

  An embodiment of the drooping restraint brace structure 1 of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the sagging restraining arm bracket 2 constituting the droop restraining arm structure 1 includes an arm main body 4 and a backing member attached to the wooden eaves beam 3 with the wooden eaves beam 3 interposed therebetween. 5, the wooden eaves beam 3, the arm main body 4, the tightening fixing member 6 for tightening and fixing the backing member 5, and the pressing member 7 for pressing the arm main body 4 away from the outdoor side surface of the wooden eaves beam 3. The overhang adjusting tool 8 is used as a main component.

  The arm main body 4 has a long arm 10 for fixing a roof material such as the eaves unit 9 extending in the direction of the eaves and a base end of the arm 10 fixed to an outdoor side surface by welding at a right angle. The mounting plate 11 is provided. The arm 10 has a gentle slope upward so that its tip is lowered, but the present invention is not limited to this. The arm 10 is fixed at a position below the center of the outdoor side surface 11 a of the mounting plate 11 so that the load of the saddle unit 9 is applied to the center below the mounting plate 11. A plurality of through holes 12 are formed at equal intervals in the vertical direction above both sides of the mounting position of the arm 10. Further, the arm 10 is provided with the required number of through holes 12 for fixing members extending in the eaves direction.

  The size and shape of the mounting plate 11 are not particularly limited, but when attached to the outdoor side surface of the wooden eaves beam 3, the lower side fixing the base portion of the arm 10 is from below the wooden eaves beam 3. It is preferable that the height is approximately equal to or slightly longer than the height of the wooden eaves beam 3 so that it protrudes and the indoor side surface 11b of the mounting plate 11 faces the outdoor side surface of the wooden eaves beam 3. There is no particular limitation. The width in the horizontal direction is not particularly limited, but if the area of the mounting plate 11 is increased, the load receiving area is increased, so that the occurrence of indentation and wood thinning is reduced, and other circumstances are allowed. If so, the larger one is desirable.

  The backing member 5 is provided with reinforcing plates 14 on the indoor side surfaces 13b on both sides of the through-hole 12 of the backing plate 13 in which the through-hole 12 is formed at a position opposed to the through-hole 12 formed in the mounting plate 11. Become. Although the size and shape of the backing plate 13 are not particularly limited, the wooden eaves beam 3 is paired with the mounting plate 11 and clamped and fixed from both sides, so that it abuts the wooden eaves beam 3. It is desirable that the length be the same. In this embodiment, two sets of backing plates 13 having a small width are used, but a single plate material having the same width as the mounting plate 11 may be used.

  The overhang adjustment tool 8 is a pressing member 7 made of a bolt or the like having a male screw threadedly engaged with a screw hole 15 formed below the backing plate 13, as shown well in FIG. The front end of the pressing member 7 passes through the through hole 16 of the wooden eaves beam 3 so as to contact the lower side of the indoor side surface 11 b of the mounting plate 11. Then, by rotating the bolt head 7a protruding from the backing plate 13 with a wrench or the like, the pressing member 7 presses the mounting plate 11 in the outdoor direction, and a load applied to the wooden eaves beam 3 from the mounting plate 11 is applied. Suppress. In FIG. 4, a nut 19 is a nut fixed to the indoor side surface 13 b of the backing plate 13 in order to increase the screwed portion with the bolt 7 a, and a nut 20 is a nut for preventing the pressing member 7 from loosening.

  Further, as shown in FIG. 5, instead of forming the screw holes 15 in the backing plate 13, a pressing member 7 such as a bolt is attached to a cylindrical screw 17 in which a screw is formed on the inner periphery embedded in the wooden eaves beam 3. As shown in FIG. 4, the backing plate 13 is provided with a passage hole 18 of the pressing member 7 and the bolt head 7a protruding from the passage hole 18 is rotated using a wrench or the like. In addition, the amount of overhang may be adjusted by operating the pressing force on the mounting plate 11 at the tip of the pressing member 7. In this embodiment, the through hole 16 formed in the wooden eaves beam 3 is passed, but instead, the lower part of the backing plate 13 shown in FIG. 4 is extended to form the screw hole 15 in the extended part. It may extend outward through the wooden eaves beam 3. In this case, the through hole 16 is not passed.

  Bolt holes 12 are formed in the backing plate 13 at positions corresponding to the through holes 12 provided in the mounting plate 11, and bolts 6 a constituting the fastening member 6 are formed in the mounting plate 11. The nut 21 is screwed into the threaded portion 6b protruding from the through-hole 12 through the through-hole 12 and the through-hole 16 of the wooden eaves beam 3 and tightened, whereby the arm main body 4, the wooden eaves beam 3, and the backing member 5 is integrally tightened and fixed. As a result, the load of the heel unit 9 on the arm 10 is transmitted from the mounting plate 11 to the backing plate 13 via the pressing member 7, so that the load pressure on the outdoor side surface of the wooden eaves beam 3 is large. To be reduced. Since the load pressure applied to the backing plate 13 is transmitted to the lower side of the backing plate 13 via the pressing member 7, the reinforcing plate 14 which is long in the vertical direction is provided on the indoor side surface of the backing plate 13. The force is distributed over the entire surface of 13. Further, as shown in FIG. 2, if the reinforcing members 14 are provided on both sides of a row of through holes 12 arranged in the vertical direction, the reinforcement is more effective. The force acting on the backing plate 13 plays the role of receiving not only the pressing member 7 but also the pulling force to the outdoor side acting above the mounting plate 11 via the bolt 6a.

  In this embodiment, the example in which the bolt 6a and the nut 21 are used as the fastening member 6 has been described. Instead, the mounting plate 11 of the arm main body 4 and the wooden eaves beam 3 are sandwiched. The backing plate 13 may be fastened and fixed with a long fastening member such as a rope in a direction perpendicular to the longitudinal direction of the wooden eaves beam 3.

  The above-described drooping restraint arm structure 1 attached to the wooden eaves beam 3 using the above-described drooping restraint arm bracket 2 is as shown in FIG. 1, but in FIG. Although only the metal fitting 2 can be seen, two sets of two sets are used as shown in FIG. On the outdoor side of the inner wall 22 and the mounting plate 11 attached to the wooden eaves beam 3, an outer wall 23 is provided with a slight gap. The outer wall 23 is formed with a slit-like opening 23a through which the root portion of the arm 10 passes, and from the gap between the opening 23a and the roof material such as the eaves unit 9 installed above the arm 10. A drainer 24 is provided to prevent rainwater intrusion. Further, an auxiliary attachment member 27 for attaching an eaves-back ceiling member 26 to the lower side of the C-shaped steel 25 which is a framework of the arm unit 10 and the anchor unit 9 fixed to the through hole 12 provided in the arm 10 with bolts. Is provided. Further, the eaves end of the eaves unit 9 is provided with a eave 28, and the decorative attachment 29 is attached to the eaves end of the auxiliary attachment member 27.

  According to the drooping restraint brace structure 1 of the present invention having the above-described configuration, even if the load of the roof material such as the raft unit 9 is applied to the wooden eaves beam 3 via the mounting plate 11 over time, The pressing member 7 receives and is transmitted to the backing plate 13. Since the backing plate 13 is fastened and fixed to the wooden eaves beam 3 and the mounting plate 11 by the fastening fixing member 6, the force is distributed to these members, so that the force is applied to specific parts of the wooden eaves beam 3. It does not act, and as a result, digging and thinning of the wood occur, and the tips of the roofing material such as the arm 10 and the eaves unit 9 do not hang down. In addition, since the overhang adjustment tool 8 can be adjusted each time the degree of sag increases, roof materials such as fences can always be kept in an appropriate position, and the appearance of the building can be improved.

  The drooping restraint brace structure 1 using the drooping restraint brace 2 can be applied not only to newly built buildings but also to repairing existing buildings with drooping roof members such as fences. Many demands can be expected.
