Herringbone steel plate inner gutter

Abstract

The invention provides a herringbone steel plate inner gutter, which includes a steel plate inner gutter structure, the steel plate inner gutter includes two side walls and a bottom plate, upper flanges are provided on the top of the two side walls, and the two side walls and the bottom plate are formed by cold bending. The longitudinal slope of the bottom plate is 5%, and the two lower ends of the bottom plate are provided with flat plate areas. The distance between them is 1500mm, and the model of reinforced angle steel is L30x3.0. The invention provides a herringbone steel plate inner gutter, which has high structural rigidity and long service life, and solves the problem that the existing steel plate inner gutter structure is easily deformed due to heavy rainwater. The slope is 5%, which improves the drainage performance and solves the corrosion and leakage caused by the accumulated water in the existing steel plate inner gutter structure due to the inability to ensure the slope; it can be widely used in single and multi-storey industrial steel structure buildings. Internal gutter drainage system.

Description

technical field [0001] The invention relates to a steel plate inner gutter structure in industrial steel structure buildings, in particular to a herringbone steel plate inner gutter. Background technique [0002] The application of light portal frame structures in my country began in the early 1980s. After nearly 20 years of continuous development, there are currently tens of millions of square meters of light steel construction projects in China every year, mainly for light factory buildings. , warehouses, gymnasiums, exhibition halls and prefabricated houses, extra-storey buildings, etc. The light portal steel frame is a steel structure widely used at present, especially in the application of industrial plants, it has many advantages such as light weight, environmental protection, energy saving, high efficiency, high degree of industrialization, and convenient construction. [0003] In single- and multi-storey steel structure industrial construction projects, the gutter is...

Problems solved by technology

[0008] The purpose of the present invention is to provide a herringbone-shaped steel plate inner gutter, which can solve the problem of corrosion and leakage caused by water accumulation in the gutter caused by the inability of the existing steel plate inner gutter to ensure the slope, and at the same time, can enhance the overall rigidity of the gutter to solve the inner gutter. The gutter sagging and deflection is large due to the large amount of rainwater
