Description

  The present invention relates to a drainage structure of an inclined floor surface portion, and more particularly, to at least one drainage drain provided on an inclined floor surface portion having a drainage gradient on the surface and disposed at a downstream edge portion of a main drainage gradient of the inclined floor surface portion. It is related with the drainage structure of the inclined floor surface part for flowing down surface water toward.

  For example, a balcony or veranda provided in a detached house or the rooftop of a building is an outdoor area exposed to wind and rain, so drainage gradients are provided on these floors to smooth out surface water such as rainwater. Various ideas have been made to enable the discharge to be performed (see, for example, Patent Document 1). For example, a side groove is provided in an edge portion along the sleeve wall or handrail on the floor surface of a balcony, veranda, or the like that is partitioned by a sleeve wall or a handrail, etc., and for example, by a gentle inclination of about 1 to 2 °. By forming a drainage gradient on the floor surface, the surface water flows down toward the side groove, and the surface water is discharged through a drainage drain provided in communication with the side groove.

Also, the work of providing drainage gradients on floors and side grooves such as balconies and verandas was generally done by plastering using mortar, etc., but such plastering requires skill and labor. This is an operation. For this reason, for example, a technique for forming a sloped floor surface portion having a drainage gradient by laying a plurality of sloped floor panel members made of a foamed resin material provided with a slope on the surface in a vertical and horizontal direction (for example, Patent Document 2). And a technique (for example, refer to Patent Document 1) in which a plurality of unit gradient bottom members made of a foamed resin material having a predetermined gradient are continuously arranged to provide a gradient in the side groove.
