Description

本発明は、屋根面材が取り付けられた樋により排水する屋根構造体に関する。 The present invention relates to a roof structure that drains water by a gutter to which a roof surface material is attached.

屋根構造体は、一般に、屋根面に設けられた屋根面材と、溝状の樋を備えている。雨天時に、屋根構造体は、屋根面材で雨水を受けて、樋により雨水を排水する。また、従来、フレーム体の奥行方向梁に沿って雨樋（樋）を設け、屋根体（屋根面材）の縁部を雨樋に取り付けた屋外構造体が知られている（特許文献１参照）。 The roof structure generally includes a roof surface material provided on the roof surface and a groove-shaped gutter. When it rains, the roof structure receives rainwater from the roof surface material and drains the rainwater from the gutter. Further, conventionally, an outdoor structure in which a rain gutter (gutter) is provided along a beam in the depth direction of a frame body and an edge of a roof body (roof surface material) is attached to the rain gutter is known (see Patent Document 1). ).

特許文献１に記載された従来の屋外構造体では、雨樋は、屋根体から受ける雨水を排水するため、水勾配を有しており、奥行方向梁の長手方向に対して傾斜した状態で、奥行方向梁に取り付けられる。そのため、雨樋と奥行方向梁が平行ではなく、雨樋の両端部で、奥行方向梁に対する取付位置にズレが生じて、奥行方向梁に取り付けた雨樋の意匠性が低下することがある。また、屋根体は、雨水を雨樋に向かって流すため、水勾配を有しており、水下側に位置する雨樋に取り付けられている。雨樋と屋根体のそれぞれが水勾配を有することで、屋根体が捻じれるように２つの水勾配の方向に傾き、屋根体の意匠性が低下することもある。 In the conventional outdoor structure described in Patent Document 1, the rain gutter has a water gradient in order to drain the rainwater received from the roof body, and is inclined with respect to the longitudinal direction of the depth beam. It is attached to the depth direction beam. Therefore, the rain gutter and the depth direction beam are not parallel, and the mounting position with respect to the depth direction beam may be displaced at both ends of the rain gutter, and the design of the rain gutter attached to the depth direction beam may be deteriorated. In addition, the roof body has a water gradient to allow rainwater to flow toward the rain gutter, and is attached to the rain gutter located on the underwater side. Since each of the rain gutter and the roof body has a water gradient, the roof body is tilted in the directions of the two water gradients so as to be twisted, and the design of the roof body may be deteriorated.
