Arc self-bearing gutter

Abstract

The invention relates to an arc self-bearing gutter. The arc self-bearing gutter includes an arc wallboard and a flange roll rim which are cold-bending integrated, the flange roll rim is located at the upper end of the arc wallboard, and the flange roll rim and the arc wallboard are surrounded to form a closed rectangular section; and two ends of the arc wallboard are provided with supporting bases which are located at the bottom portions of the arc wallboard and the flange roll rim, the inner side of the arc wallboard is provided with a supporting rod, and a drain gully is formed in the bottom of the arc wallboard and is further connected with a roof drain. The arc self-bearing gutter is simple in structure and high in drainage efficiency, is not prone to store water, and can realize higher span self-bearing. The arc wallboard and the flange roll rim are cold-bending integrated with thin-wall steel plate, are convenient to manufacture, are wide in material selecting, meet the environmental requirement of green building material, and are economical and environmentally friendly. The arc self-bearing gutter possesses high adaptability in large-scale house surface drainage system, concise and attractive appearance, and outstanding economic benefits and wide market application prospects.

Description

technical field [0001] The invention relates to roof drainage facilities, more specifically, to an arc-shaped self-supporting gutter. Background technique [0002] In the organized drainage system of large-scale industrial or civil factory buildings, gutters are an important part of collecting rainwater and connecting ground drainage facilities. Industrial factory buildings have large roof spans and relatively large catchment areas, especially the emergence of multi-span factory buildings, and the drainage gutters on large roofs have a direct impact on the normal production in the factory buildings. Therefore, a gutter with high drainage efficiency, energy saving and environmental protection, and stability and reliability has significant economic benefits and broad market application prospects. [0003] The roof drainage gutter of the prior art has the following disadvantages: [0004] (1) There are many parts and complex structures that make up the gutter, and there are a...

AI Technical Summary

Problems solved by technology

[0004] (1) There are many parts and complex structures that make up the gutter, and there are a lot of factory welding or on-site splicing between the parts, which leads to very cumbersome post-construction production and on-site installation, which consumes a lot of manpower and material resources

[0005] (2) The conventional gutter adopts a rectangular cross-section, which has a large drainage wetted area and a small hydraulic radius, so the drainage efficiency is low, the unit consumption is large, and the overall energy efficiency is low; and the rectangular cross-section gutter is prone to deformation, resulting in the accumulation of Water or debris deposits clogging, causing gutter rust

[0006] (3) Conventional gutters have not taken into account comprehensive factors such as applicability, energy saving, environmental protection, economy and aesthetics
