Description

  The present invention relates to a simple structure having a down-gradient roof with a roof panel placed on a rafter, and more particularly to an improvement of a rainwater drainage structure of such a simple structure.

In conventional simple structures such as terraces and carports, rain gutters are provided to prevent rainwater from falling from the eaves of the roof. A rain gutter is usually constructed by installing a horizontal gutter on the front frame of the roof, attaching a vertical gutter made of PVC pipe on the side of one pillar with a saddle fitting, and connecting the gutter and gutter with a bellows-like connecting pipe etc. is there. The downspout sticks out as if attached to the periphery of the pillar, which detracts from the beauty of the simple structure. Therefore, as described in Patent Document 1 and Patent Document 2, a structure in which a hollow vertical rod portion is provided inside a column and an external vertical rod is eliminated has been proposed.
