(2) the drain gully structure of gutter is unreasonable, and downpipe is directly accessed cell body, is unfavorable for draining.
(3) control of gutter span is the most rigorous, and particularly industrial premises local post is away from relatively big or take out at post, owing to span is excessive, overall collapse deformation easily occurs, causes the generation of security incident.
(4) gutter material generally uses ordinary carbon steel, and the environment residing for gutter is more severe, for rainwater submergence environment, belong to medium erosion degree, ordinary carbon steel is susceptible to the corrosion phenomena at corrosion, especially welding position and splicing position in such a case and generally exists, and causes the later stage to leak.
Utility model content
The purpose of this utility model is to overcome the existing self-supporting easy buckling deformation of formula gutter to cause security incident, and the problem that corrosion and causing leaks easily occurs.
For this, this utility model provides a kind of cold bending thin wall type self-supporting formula gutter, including draining cell body, described draining cell body includes one-body molded base plate, web, flange plate and the edge of a wing crimping being sequentially connected with, described web is arranged on the dual-side that base plate is relative and upwardly extends, and flange plate is arranged on web and extends to web outside, and edge of a wing crimping is extended on the downside of flange plate, being provided with drain gully on described base plate, described base plate bottom surface connects roof drain at drain gully.
Further, above-mentioned base plate, web, flange plate, edge of a wing crimping junction angle two-by-two is 90 degree.
Further, the thickness of above-mentioned base plate, web, flange plate and edge of a wing crimping is 2~6mm.
Further, the depth-width ratio of above-mentioned base plate, web, flange plate and each plate of edge of a wing crimping is 1:5~1:2.
Further, above-mentioned roof drain includes the funnel on top and the straight tube of bottom.
Further, above-mentioned drain gully is positioned at the center of bottom end.
Further, a diameter of the 250~300mm of above-mentioned drain gully.
Further, the span of above-mentioned draining cell body is 6~12m.
Further, above-mentioned draining cell body and roof drain are prepared by weathering steel or stainless steel.
The beneficial effects of the utility model:
(1) this cold bending thin wall type self-supporting formula gutter simple in construction that this utility model provides, reasonable stress, there is good draining usefulness, gutter uses light-gauge steel section clod wash one-body molded, simple for production, it is easy to install, the span of 6~12m can be realized, without ad hoc support frame structure, it is achieved the self-supporting of gutter.
(2) this cold bending thin wall type self-supporting formula gutter that this utility model provides uses weather-proof steel or stainless steel, antiseptic effect in erosion environment is more preferable, service life is longer, the corrosion caused when being prevented effectively from ordinary carbon steel weld or deform excessive, causes the phenomenon leaked.
(3) this cold bending thin wall type self-supporting formula gutter strong adaptability in the engineering design of building surface in big industrial factory roof drainage system that this utility model provides, meet green building material requirement, more energy efficient environmental protection, has significant economic benefit and wide market application foreground.
Below with reference to accompanying drawing, this utility model is described in further details.
