Arrangement at gutters in roofs for slope to the sides of the gutters, which have outlets in the form of sinks and spouts. The object of the invention is to produce a gutter of the aforesaid kind, which renders it possible to assemble a gutter corresponding to the special roof requirements with respect to the number of sinks, overflows etc. and to provide a gutter, which can be repaired without therefore requiring the entire gutter to be dismantled. The invention further renders possible an accurate horizontal positioning irrespective of possible differences in height in the carrying structure or the roof. Differences in height in this context are to be understood to refer to the small variations possibly prevailing in height position from one truss to the other and lying within permissible construction tolerances. The invention further ensures by simple means the prevention of ice formation at the gutter edges. The invention implies that at least one section (1) at the outer edge of the roof (outer section) is provided with at least one sink (6) having its inlet in the same plane as the bottom (2) of the section, a first outflow (8) connected to a second sink (7), and a second overflow (10) of higher location connected to a spout (9). |
