The gutter is a component of the roof drainage system. The gutter is mainly used to temporarily collect rainwater, which is timely drained through the downpipe.
In large plants, the steel consumption of steel plate gutters is also a large part, but steel plate gutters also have their own advantages, and the wind load in coastal areas is generally large. If the color plate gutter is used, under the strong wind load, the color plate gutter appears weak and vulnerable to being lifted by the wind suction. The design of the steel plate gutter also has a great impact on its durability, so the design and material selection of the steel plate gutter cannot be ignored.
Common gutter materials are 1.2mm, 2mm or 2.5mm thick stainless steel; 3mm or 5mm thick galvanized steel plate; It shall be comprehensively considered according to the importance, cost and grade of other materials used. The gutter depth of general civil buildings shall not be less than 250mm, which shall be reasonably determined according to the clearance between the bottom of the roof panel and the roof truss top, and the space required for gutter slope adjustment shall be considered. When determining the width, consider the following two factors: * First, calculate whether the drainage can pass through* 2、 The commonly used gutter slab is 1.0m, 1.2m and 1.5m wide. The slab shall be reasonably used as far as possible. For buildings with high requirements, the gutter must be designed to be retractable.
