The present invention relates to a horizontal drainage drain structure for draining rainwater .

Water generated in common corridors and verandas of condominiums (hereinafter abbreviated as “veranda etc.”) is generally drained through a drainage opening in the corner of the bottom wall. A box-shaped box is installed on the veranda or the like, and a drainage mounting hole is formed in the vertical wall at the corner between the bottom wall and the vertical wall of the box-shaped box, and the box is attached to the drainage mounting hole. There is known a horizontal drainage drain device for draining rainwater collected in a ridge (see, for example, Patent Document 1).

  4 is an exploded perspective view showing such a conventional horizontal drainage drain device 200. FIGS. 5 (a), 5 (b), 6 (c), and 6 (d) are horizontal views shown in FIG. It is a longitudinal cross-sectional view which shows the drainage drain apparatus and the horizontal drainage drain structure which uses this.

  That is, a box-shaped ridge 100 formed in a box shape with an open top is installed on the veranda or the like, and the vertical wall 102 side in the corner 110 between the bottom wall 101 and the vertical wall 102 of the box-shaped ridge 100 is provided. The drainage attachment hole 103 is opened, and the horizontal drainage drain device 200 is attached to the established drainage attachment hole 103 to drain the water generated on the veranda or the like.

  Specifically, the horizontal drainage drain device 200 is disposed outside the vertical wall 102 via the drain main body 201 installed inside the vertical wall 102 of the box-shaped bowl 100 and the vertical wall 102 of the box-shaped bowl 100. The support plate 202 is installed, and the drain main body 201 and the fixing screw 203 that sandwiches the support plate 202 are configured.

  Then, the mounting hole 212 opened in the support plate 202 is superposed on the outside of the drainage mounting hole 103, and the support plate 202 is brought into contact with the outer surfaces of the bottom wall 101 and the vertical wall 102, and the superposed drainage mounting hole 103. And the drain pipe insertion cylinder part 211 which protruded toward the outer side of the drain main body part 201 toward the attachment hole 212 penetrates from the inner side of the vertical wall 102 [refer Fig.5 (a). ].

  Further, if the fixing screw 203 is inserted and screwed into the penetrating drain pipe insertion cylindrical portion 211 from the tip of the drain pipe insertion cylindrical portion 211, the support plate 202 is vertically moved as shown by an arrow in the figure. The drain tube insertion tube portion 211 is pulled outward from the outside of the wall 102 and the drain main body portion 201 is crimped from the inside of the vertical wall 102 (see FIGS. 5B and 6C). ].

  That is, when the horizontal drainage drain device 200 is attached to the drainage attachment hole 103 of the box-shaped bowl 100 as described above, the drain main body 201 and the support plate 202 are pressure-bonded in a direction in which the vertical wall 102 is sandwiched. However, it could not be pressure-bonded in the vertical direction that sandwiches the bottom wall 101.

  Therefore, as shown in the enlarged view of FIG. 6D, a joint portion between the bottom wall 101 of the box-shaped bowl 100 and the drain main body 201, specifically, the drain main body 201 joins the bottom wall 101. As shown by the arrow in the figure, the crimping force between the extension piece 221 and the bottom wall 101 is weakened, and the water w accumulated in the vicinity of the joint portion passes through a slight gap t or by capillary action. There was a risk of leaking to the outside of the box-shaped basket 100 through the end of the extended piece 211 or between the support plate 202 and the fixing screw 203.
