Description

  The present invention relates to an eaves rod suspension device provided with an ear portion support portion for fitting and supporting an ear portion of an eaves rod.

  2. Description of the Related Art Conventionally, an eaves rod suspension device having an ear portion support portion for fitting and supporting an ear portion of an eaves rod is known.

  The conventional eaves hanging tool 6 is formed by bending a band-shaped metal plate.

  This conventional eaves rod suspension 6 has a substantially U-shaped ear portion support portion 4 for fitting and supporting the ear portions 3 provided at both upper ends of the eave rod 2 at both ends of the eave rod suspension body 1. And a detachment prevention piece 5 having elasticity facing the inner surface side of the ear 3 of the eaves 2 fitted to the ear support 4 is provided on the eaves hanger body 1.

  The disengagement prevention piece 5 is generally a flat plate shape as shown in FIG. 5, and for this reason, as shown in FIG. 5 to FIG. When the ear part 3 of the eaves 2 is pushed in through a small gap between the tip part and the tip part of the separation preventing piece 5 and the ear part is fitted into the ear support part 4 and supported, it comes off as shown in FIG. There is a case where the prevention piece 5 is plastically deformed so as to face obliquely upward and cannot be restored. In this way, if the detachment prevention piece 5 is plastically deformed so as to face obliquely upward and does not return to its original state, the inner surface of the eaves bowl 2 in which the ear portion 3 is fitted and supported in the substantially U-shaped ear portion support portion 4 When an external force acts such that the ear 3 of the eaves 2 is detached from the ear support 4 due to a strong wind or the like, the gap between the tip of the disengagement prevention piece 5 increases, and the ear from the enlarged gap. 3 may come off.

  Further, in this conventional example, when the eaves rod 2 slides, the edge part of the leading edge of the flat plate-shaped disengagement prevention piece 5 hits the inner surface of the eaves rod 2, and the eaves rod 2 slides smoothly. There is a problem that it is difficult.

  Therefore, in a state where the ear portion 3 of the eaves rod 2 is fitted and supported on the ear support portion 4, the distal end portion of the disengagement prevention piece 5 is bent upward in an L shape so that the eaves rod 2 can be smoothly slid. Japanese Patent Application Laid-Open No. H10-228867 discloses a structure in which a bent portion 7 is provided so that the outer surface of the upward piece 9 of the L-shaped bent piece 7 at the leading edge of the disengagement prevention piece 5 faces the inner surface of the eaves 2. Yes.

However, in this conventional example, since the L-shaped bent piece portion 7 is formed by bending a metal plate, the longitudinal section of the corner portion is rounded. Therefore, when an external force acts on the eaves rod 2 due to a strong wind and the L-shaped bent piece portion 7 is pushed sideways by the inner surface of the eaves rod 2, the round shape of the corner portion of the L-shaped bent piece portion 7 The formed part slides up on the inner surface of the eaves rod 2, and the detachment prevention piece 5 is deformed obliquely upward as shown by the broken line in FIG. 7, so that the ear portion 3 of the eaves rod 2 is easily detached from the ear support portion 4. There's a problem.
Japanese Utility Model Publication No. 7-29163

  The present invention has been invented in view of the above-described conventional problems, and the eaves of the eaves have good sliding properties, and the eaves are not easily detached from the ear support even when a strong wind blows. It is an object to provide a tool.

In order to solve the above-mentioned problem, the eaves-hanging tool according to the present invention has a substantially U-shape for fitting and supporting the ears 3 provided at both upper ends of the eaves-hook 2 at both ends of the eaves-hook main body 1. And a detachment prevention piece 5 having elasticity that opposes the inner surface side of the ear portion 3 of the eaves hook 2 fitted into the ear support portion 4 on the eaves rod suspension body 1. a eaves gutter hangers 6 provided, the L-shaped bent piece portion 7 bent in L shape upwardly the tip portion of the preventing piece 5 above deviates provided, in a part of the corner portion of the L-shaped bent piece 7 Protrusions 8 projecting toward the ear support 4 side are provided , and the upwardly facing piece 9 of the L-shaped bent piece 7 is inclined obliquely upward so as to be positioned on the ear support 4 side as it goes upward. The upward piece 9 is formed in an arc shape projecting toward the ear support portion 4 toward the center in plan view, and the projection 8 is more than the tip of the projection 8 in plan view. Site of the upper edge of the corresponding upward piece 9 is characterized in that the projecting ear portion supporting portion 4 side.

By adopting such a configuration, the distal end portion of the detachment preventing piece 5 is the L-shaped bent piece portion 7 so that the ear portion 3 of the eave rod 2 is supported by the ear portion support portion 4. There when slide not hit the tip of the edge portion of the preventing piece 5 out to the eaves gutters 2 internal surface, smoothly eaves gutters 2 Ru can slide. Particularly, the L-shaped bent piece portion 7 is inclined obliquely upward so that the upward piece 9 is located on the ear support portion 4 side as it goes upward, and the upward support piece 9 is at the center portion in plan view as the ear support portion. Since the part of the upper end edge of the upward piece 9 corresponding to the protrusion 8 protrudes toward the ear support part 4 side in a plan view, it is formed in an arc shape protruding to the 4 side. In the state where the ear 3 of the eaves 2 is supported by 4, the inner surface of the eaves 2 is slid while being guided by the upward-facing piece 9 which is arcuate in plan view. Unless the external force other than the external force for sliding acts on the eaves rod 2, the projection 8 does not hit the inner surface of the eaves rod 2, and the sliding property of the eaves rod 2 is further improved. In addition, even if a strong wind acts on the eaves rod 2 and the L-shaped bent piece portion 7 slides upward on the inner surface of the eave rod 2 and the detachment preventing piece 5 tries to deform obliquely upward, the L-shaped bent piece portion 7 When it slides upward, the protrusions 8 slightly bite into the inner surface of the eaves 2 so that the further L-shaped bent piece portion 7 can be prevented from sliding upward, and the ear portion 3 supports the ear portion. It can prevent coming off from the part 4.

  Further, it is preferable that the corner portions on both sides of the projecting tip portion of the projection 8 are rounded in a plan view.

  As a result, when the eaves rod 2 slides, an error such as a construction error or a manufacturing error, or even if an external force acts and the projection 8 hits the inner surface of the eaves rod 2, The inner surface is slid by being guided by the rounded corner portions on both sides of the projecting tip of the protrusion 8, so that the slidability does not deteriorate.

The present invention, as described above, provided the L-shaped bent piece bent in L shape upwardly the tip portion of the disengagement preventing member, the ear support portion in a part of the corner portion of the L-shaped bent piece portion Protrusions projecting inward, and as the upwardly facing piece of the L-shaped bent piece part goes upward, it is inclined obliquely upward so as to be positioned on the ear part supporting part side, and the upwardly facing piece is in the center part in plan view. It is formed in an arc shape projecting to the support part side, and in a plan view, the upper edge part of the upward piece corresponding to the protrusion protrudes to the ear part support part side rather than the tip of the protrusion, so that the ear part slides Further, there is an advantage that the ear part is difficult to come off from the ear part support part even if a strong wind blows.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The eaves hanger body 1 constituting the main body of the eaves hanger 4 is formed by bending a belt-shaped metal plate with a press. As shown in FIG. 1, the eaves hanger body 1 has inclined piece portions 11 in which both end portions of the central piece portion 10 in the longitudinal direction protrude obliquely upward and outward, and the tip portions of both inclined piece portions 11. The ear | edge part support part 4 made substantially U-shaped is formed.

  In addition, the guide piece 13 is integrally formed by bending downward from a portion corresponding to the tip of the lower horizontal piece portion 12 of the one ear portion support portion 4 among the both ear portion support portions 4.

  The lower end portion of the suspension bolt 15 is fixed to the central portion of the central piece portion 10 of the eaves / hanger main body 1 having the above-described configuration by a nut 16.

  Further, the rear end portions of the detachment preventing pieces 5 having elasticity are fixed to both end portions of the lower surface portion of the central piece portion 10 of the eaves hanger body 1 by fixing tools 18.

  The detachment prevention piece 5 is formed of an elastic band-shaped metal plate as shown in FIG. 4, and is provided with an L-shaped bent piece portion 7 whose upper end is bent in an L shape. A protrusion 8 that protrudes toward the ear support 4 side is provided on a part of the corner portion of the piece 7.

  The protrusions 8 are provided at two locations in the width direction of the corner portion of the L-shaped bent piece portion 7, and the protrusions 8 are formed by cutting up a part of the corner portion. Further, the corner portions 19 on both sides of the projecting tip portion of the protrusion 8 in a plan view are formed into a corner shape 19.

  The upward-facing piece 9 of the L-shaped bent piece 7 is formed in an arc shape protruding toward the ear support 4 toward the center in plan view, and further, as shown by the solid line in FIG. It inclines toward diagonally upward so that it may be located in the support part 4 side.

  Here, in a plan view, the upper end edge portion of the upward piece 9 corresponding to the protrusion 8 is displaced from the tip of the protrusion 8 toward the ear support 4 side.

  Further, a semicircular bent portion 20 is provided at the rear portion of the detachment preventing piece 5 so as to be more easily elastically deformed.

  The eaves hanger 4 having the above-described configuration is used to suspend and support the eaves 2 on the eaves of the roof of the building. In particular, it is used for hanging and supporting large eaves.

  The eaves cage 2 that is suspended and supported by the eaves implement hanger 4 of the present invention has a substantially U-shaped cross section that opens upward, and is configured by providing ears 3 at the upper ends of both side pieces (FIG. In this embodiment, ears 3 projecting outward are provided at the upper ends of both side pieces).

  At the time of construction, the suspension bolt 15 of the eaves anchor 4 is attached to the eaves of the roof of the building (for example, the end of the folding roof), and the ear 3 on one side of the eaves 2 is attached to the eave anchor. 4 by pushing in from between the tip of the lower lateral piece 12 of the lower side piece 12 and the tip of the elastic detachment prevention piece 5 and deforming the detachment prevention piece 5. The ear 3 on one side is fitted into the ear support 4 having a substantially U shape.

  Next, a guide in which the ear 3 on the other side of the eaves 2 is suspended below the tip of the lower lateral piece 12 of the other substantially U-shaped ear support 4 of the eaves hanger 4. While pushing upward along the piece 13 and deforming the other elastic detachment prevention piece 5 upward, the tip of the detachment prevention piece 5 and the tip of the lower lateral piece 12 of the ear support 4 The other ear portion 3 is pushed into the other ear support portion 4 having a substantially U-shape by pushing upward from a small gap therebetween.

  Thus, the both ear portions 3 of the eaves rod 2 are fitted and supported in the both ear portion support portions 4, so that the eave rod 2 is supported by being suspended from the eaves rod suspension 4.

  By the way, a strong wind blows after construction, and the eaves bowl 2 may be deformed so as to be pushed from the position of the solid line in FIG. 3 to the position of the broken line. In this case, at first, the upward piece 9 of the disengagement prevention piece 5 is pushed by the inner surface of the eaves bowl 2, and the upward piece 9 is inclined obliquely while sliding up the inner surface of the eaves bowl 2. When the tip of 8 hits the inner surface of the eaves rod 2 and the tip of the protrusion 8 hits the inner surface of the eaves rod 2 and the eaves rod 2 is further pressed by a strong wind, the tip of the protrusion 8 slightly bites into the inner surface of the eaves rod 2 Thus, the deformation prevention piece 5 is not further deformed, and the eaves 2 is prevented from being detached from the eaves hanger 4.

  When the eaves rod 2 is slid during construction, or when the eaves rod 2 is slid due to expansion and contraction of the eaves rod 2 after construction, the tip portion of the disengagement prevention piece 5 is made an L-shaped bent piece portion 7. Thus, when the eaves rod 2 slides while the ear portion 3 of the eaves rod 2 is supported by the ear support portion 4, the edge portion of the tip of the disengagement prevention piece 5 does not hit the inner surface of the eave rod 2, and the eave rod 2 smoothly The heel 2 can slide. In this case, the upward piece 9 is further formed in an arc shape that protrudes toward the ear support 4 in the plan view, and the upper end of the upward piece 9 corresponding to the protrusion 8 rather than the tip of the protrusion 8 in plan view. Since the edge portion protrudes toward the ear support 4, the upward piece 9 in which the inner surface of the eaves 2 is arcuate in plan view with the ear 3 of the eaves 2 supported by the ear support 4. In this case, the protrusion 8 does not hit the inner surface of the eaves 2 unless an external force other than the external force for sliding acts on the eaves 2 Even more, the easiness of the eaves 2 is improved.

  In addition, when the eaves rod 2 slides, even if an error such as a construction error or a manufacturing error or an external force acts and the projection 8 hits the inner surface of the eaves rod 2, the plan view Since the corner portions on both sides of the protruding tip portion of the protrusion 8 are rounded, the inner surface of the eaves 2 is guided and slid by the rounded corner portions on both sides of the protruding tip portion of the protrusion 8. The slide performance does not deteriorate.
