Description

  The present invention relates to a technique for attaching a vertical gutter with a retaining metal.

  Conventionally, in order to attach a downspout to the outer wall of a building, as shown in Patent Document 1, an arbitrary position in the up-down direction of the downspout is wrapped in an annular shape by a holding part provided in a metal fitting fixed to the outer wall. In general, it was attached to the outer wall by holding it.

  However, in the conventional example as shown in Patent Document 1, since the vertical hook is held in an annular shape by the holding part of the holding metal fitting, the holding part in the vertical direction of the vertical hook is used. There is a problem that a difference in level occurs and an uncomfortable appearance occurs.

  In addition, an annular projection protrudes from the connecting cylinder portion connecting the vertical rod and the vertical rod in a substantially intermediate portion in the vertical direction. And the lower end of the upper vertical gutter and the upper end of the lower vertical gutter are fitted on the lower part, respectively, so that the outer surface of the upper and lower vertical gutters and the outer surface of the annular protrusion are flush with each other, and the outer wall of the building For example, Patent Document 2 proposes that a vertical rod is attached to an outer wall by fitting a fitting connecting portion provided at a front end portion of a holding metal fitting to a mounting projection portion of a connecting cylinder portion. ing.

  In the conventional example shown in this Patent Document 2, the outer surface of the upper and lower vertical shafts and the outer surface of the annular projecting portion are flush with each other, so that the appearance is improved. Since the annular protrusion is exposed, a sense of incongruity occurs at this point. Moreover, in this Patent Document 2, it can be attached to the outer wall of the building with a metal fitting only at the part where the vertical gutter and the vertical gutter are connected by the connecting cylinder part, and it corresponds to the mounting pitch to the outer wall by the metal fitting. It is necessary to cut down the downpipe. In addition, when the upper and lower vertical hooks expand and contract due to heat, the connecting cylinder portion is fixed to the outer wall, so that the vertical hook may be deformed or detached from the connecting cylinder.

  In addition, an inner cylinder portion is integrally formed on the inner side of the back surface portion of the vertical shaft, and a slit communicating with the inner tube is formed on the rear surface portion of the vertical wall in the vertical direction. An enlarged insertion hole for inserting the head of the bracket is formed at an appropriate interval, and the head of the bracket is inserted into the inner cylindrical portion from the insertion hole so that the head of the bracket is shifted vertically from the insertion hole. The vertical gutter or the retainer is moved so as to move relative to each other, and in this state, the vertical member is attached to the outer wall of the building by tightening the fastening member screwed to the shaft portion of the retainer to the back of the vertical gutter. This is known from Patent Document 3.

However, in the conventional example shown in Patent Document 3 above, after attaching a plurality of retainers in a row in the vertical direction on the outer wall, the vertical hook is positioned so as to face the retainers attached in a row. The insertion holes provided at the top and bottom in the slit part on the back of the downspout are opposed to the heads of the respective backends mounted in a row on the outer wall in this state. Insert the head, and then move the vertical rod up and down to position the head of the retainer at a position displaced vertically from the insertion hole, and then tighten the fastening member in advance. If the mounting pitch of multiple retainer brackets mounted in a row in the vertical direction is slightly different from the pitch of the multiple insertion holes provided in the vertical shaft, the insertion holes cannot be inserted into the heads of the respective retainer brackets. There's a problem. In particular, there may be a place where the shaft portion of the metal fittings cannot be fixed for some reason on the vertical part of the outer wall of the building (for example, the shaft portion of the metal fittings may be shot into the horizontal joint portion of the outer wall). In such a case, it is necessary to shoot the bracket in a position shifted up and down avoiding the location where the outer wall cannot be shot. Of course, the mounting pitch of the bracket is different in the field. In the conventional example, it is not possible to attach a downspout. In addition, when the vertical hook expands and contracts due to heat, the insertion hole provided on the back of the vertical hook may face the head part of the buckle due to the expansion and contraction of the vertical hook. There is a problem that the portion comes out of the insertion hole.
