[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a support structure for a bent joint at a corner of an eaves of a house.
[0002]
[Prior art]
Conventionally, in a dormitory type roof, a water collector has been installed at the eaves edge, and the ends of the eaves on both sides are fitted into the eaves fitting part of this water collector. The eaves eaves are arranged around the roof by connecting eave eaves on both sides using eaves bend joints. This eaves bending joint is, for example, an eaves connection that matches the outer surface shape of the eaves to be connected to both ends of the L-shaped joint body in plan view as described in Japanese Utility Model Publication No. 4-98932. A part is provided.
[0003]
[Problems to be solved by the invention]
However, the vertical cross-sectional shape of the above-mentioned joint body where the eaves connecting portion and the eaves are not fitted is almost the same as that of the eaves, and the curvature radius of the lower end corner of the entrance corner is small and square. Therefore, due to the expansion and contraction caused by the temperature change of the eaves, especially the shrinkage of the eaves, tensile stress concentrates on the lower corner of the joint corner of the joint body. There was a problem of cracking or breakage.
[0004]
In addition, when attaching the eaves and the bend joint to the eaves, it is not designed to be installed with a predetermined gap between the bend joint and the nose cover plate. When it was constructed close to the hidden plate side, there was a problem that the bent heel joint hit the nose cover plate due to the shrinkage of the eaves, causing cracks or breaking.
[0005]
An object of the present invention is to provide a support structure for a bent seam joint that does not cause cracks or breakage in the bent seam joint even if the eaves is thermally expanded and contracted.
[0006]
[Means for Solving the Problems]

The bent-fitting joint supporting structure in which the locking part of the bent-fitting joint is supported by the outdoor-side end of the hanging fixture with the indoor end fixed to the eaves corner of the building corner Because
A bent hook joint in which a protrusion is provided at an end portion on the outdoor side of the hanging tool, and a locking piece protruding downward from the locking portion is brought into contact with and locked to the protrusion. This is a support structure.
[0007]
According to a second aspect of the present invention, in the support structure for the bent joint according to the first aspect, an inverted L-shaped locking piece is erected at the outdoor end of the hanging tool, and the joint body is attached to the locking piece. The locking part is abutted and locked.
[0008]
(Function)
In the support structure according to the first aspect of the present invention, the protrusion provided at the end portion on the outdoor side of the hanger protrudes downward from the engaging portion provided on the inner surface of the corner portion on the protruding corner side of the joint body. Since the locking piece is locked by abutment, even if a compressive force or tensile force is applied to the bent joint body due to the expansion and contraction of the eaves rod, the compressive force or tensile force is When the locking piece of the locking part comes into contact with and locks the protrusion of the hanging tool, the absorption is reduced. For this reason, it is possible to prevent the bent joint from approaching the eaves side of the protruding corner of the building due to the shrinkage of the connected eaves, and cracking or breaking of the bent joint main body side There is nothing to do.
[0009]
In the support structure of the present invention according to claim 2, an inverted L-shaped locking piece is erected on the outdoor end of the hanging tool, and the locking portion of the joint main body comes into contact with the locking piece for locking. Even if the joint body tries to protrude to the outdoor side due to the compression force acting on the joint body due to the eaves being stretched, the joint body's locking part is the locking piece at the tip of the hanger Since it is hooked and locked, excessive overhanging can be prevented.

The upper surface slides and is displaced inward. At this time, since the protrusions 24 exist on both sides of the suspension part 22, both locking pieces 64 suspended from the lower surface of the locking part 62 are brought into contact with the protrusions 24 when the joint body 1 is displaced to some extent. Will be in touch.
[0030]
And since both the locking pieces 64 are the forms which are easy to deform | transform, the tensile force which acts on the coupling main body 1 is absorbed and relieved when both the locking pieces 64 deform | transform or break. For this reason, the joint body 10 is not cracked or broken on the corner side.
[0031]
In addition, the joint corner 1 is formed with an arcuate wall that swells toward the exit corner, so that the gap between the joint body 1 and the nose cover plate 4 is wider than other portions. ing. For this reason, even if the joint body 1 is deformed due to the shrinkage of the two eaves rods 3, the corner 12 of the joint body 1 does not abut against the corner 41 of the nose cover plate 4 and is not destroyed.
[0032]
【The invention's effect】
In the support structure of the bent joint of the present invention according to claim 1, the compressive force or the tensile force acting on the bent joint main body due to the expansion and contraction of the eaves is caused by the locking piece of the locking portion of the joint main body protruding from the suspension tool. As a result, for example, bent joints can be prevented from approaching the eaves side of the bent joints due to the shrinkage of the eaves, and the corners of the bent joints can be prevented. There is no crack or breakage on the part side.
