Description

  The present invention relates to a draining material for a corner.

Conventionally, the foundation corner drainer installed in the corner portion of a building is formed by sheet metal processing of one steel plate.
Patent Document 1 proposes a structure in which a single steel plate is bent and assembled without using a fixing member such as a rivet.

  Specifically, the foundation corner drainer of Patent Document 1 includes a base portion and a rising surface, and cuts both sides of the center overlap margin while leaving the center overlap margin of the upper surface of the base. Then, when the bases on both sides are bent from this cut portion, the center overlap margin and the top surfaces of the bases on both sides are overlapped. Furthermore, it is arranged on the central side surface of the rising surface that is continuous from the upper surface of the rising surface that is continuous with the upper surface of the rising surface that is continuous from the upper surface of the base surface that is stacked on the upper side, and on the central side surface of the rising surface that is continuous from the upper surface of the base material that is stacked below The engaging piece is engaged with the lower end of the engaging piece and the upper end of the engagement overlap margin.

  As a result, the rise of the upper surface of the base is suppressed, and the force for trying to return to the horizontal direction when folding and assembling is suppressed by engaging the engagement overlap margin and the locking piece with the surface side of the rising surface. Thus, the assembled state is maintained.

JP 2009-52321 A

  However, in the above conventional corner draining for protruding corners, the stacking allowance and the locking piece must be engaged with the surface side (outside) of the rising surface. During work such as installing a water drainer for the foundation, the stacking allowance and the locking piece get caught by the operator's hand or clothes and get up, loosening the engagement and creating a gap between the left and right rising surfaces. There was a risk of injury.

  In addition, since the bent state is to be maintained by engaging only the rising surface located at the upper part, the bent state of the bottom surface of the base part located at the lower part is loosened, and it is difficult to maintain a predetermined assembled shape. Therefore, in the conventional example, it is necessary to provide an overlap margin so that no gap is generated on the bottom surface.

  Further, as disclosed in Japanese Patent Application Laid-Open No. 2009-197451, when a double-sided tape for attaching a moisture permeable sheet is attached to the surface side (front surface) of the rising surface of the base corner drainer, it is engaged. Since the overlap margin and the locking piece are located on the surface side of the rising surface, a gap is easily generated due to the unevenness, and there is a risk of hindering the role of the moisture-permeable sheet.

  In the present invention, a single steel plate can be bent and assembled without using a fixing member such as a rivet, and an engagement overlap margin and a locking piece arranged on the center side surface of the left and right rising surfaces are provided. An object of the present invention is to provide a draining material for a protruding corner which is not disposed on the front surface (front surface side) of the rising surface and does not have irregularities on the front surface of the rising surface.

The plurality of through holes 40 are formed at intervals along the fold line 41. Each through-hole 40 has a rectangular shape that spans the bending line 41 and extends to the first bottom surface 23a and the second bottom surface 23b.

  According to the protruding corner drainer 10, when the one steel plate 11 is bent and assembled, the first projecting piece 47 and the second projecting piece 49 are engaged with each other on the bottom surface 23 of the base 20. Accordingly, the force acting in the horizontal direction can be regulated, and the force acting in the vertical direction can be regulated by the engagement of the third projecting piece 37 and the fourth projecting piece 39 of the rising surface 30. Without being used, the assembled shape of the draining material 10 for the exit corner can be suitably maintained, and the front surface of the rising surface 30 with the third protruding piece 37 and the fourth protruding piece 39 positioned on the rear side of the rising surface 30 Can be a smooth surface without irregularities.

A double-sided tape (not shown) is affixed to the front surface of the rising surface 30 of the draining material 10 for protruding corners, and a sheet such as a moisture permeable sheet or an airtight sheet is installed by the double-sided tape. In FIG. 1, reference numeral 60 denotes an area (tape application area) where a double-sided tape is applied.
In the protruding corner drainer 10, since the front surface of the rising surface 30 is a smooth surface without unevenness, when a double-sided tape is applied to the tape application region 60, there is a gap between the rising surface 30 and the double-sided tape. Not likely to occur. Therefore, it is possible to prevent the function of the sheet such as the moisture permeable sheet or the airtight sheet from being damaged by the gap. The position of the tape application region 60 is not limited to this example, and can be arbitrarily set as long as it is the front surface of the rising surface 30.
