Description

A metal roof siphon internal drainage system

technical field

The invention relates to a metal roof siphon internal drainage system, which belongs to the technical field of drainage.

Background technique

With the continuous development and application of steel structure buildings in recent years, it has benefited from its advantages of light weight, high rigidity, and good durability (Huang Wei, Dong Weiming. Development overview and application classification of metal roofs [J]. Building Technology, 2015,46(12):1103-1107.), it has been widely used in large-span and large-area building roofs. However, the current buildings often have strange shapes and different shapes, which makes the drainage design of special-shaped roofs very complicated (Liu Zhizhong. Discussion on the design method of rainwater drainage on special-shaped roofs[J]. Water Supply and Drainage, 2016,52(03):91-93 .). Organized drainage and unorganized drainage are commonly used at present, and the most widely used form of roof drainage is organized drainage (Liu Yan. Research on the optimization design of organized drainage of civil building roofs in severe cold areas [D]. Harbin Institute of Technology, 2015.). The commonly used unorganized drainage method is that rainwater falls to the ground along the eaves under the action of gravity, which causes great inconvenience to pedestrians. In addition, in cold winter, due to the low temperature, it is easy to form ice cones at the eaves. And there is a risk of falling at any time, which poses a great safety hazard. When there is a large amount of snow on the roof, there is also the risk of the snow falling off in a large area. Organized external drainage, in cold areas, will face a series of freezing damage problems such as ice condensation at the drain outlet, blocking the drain outlet and affecting drainage (Zhai Peng. Analysis of roof drainage in severe cold areas [J]. Building Materials and Decoration, 2020, (09 ):8-9.), and the rainwater pipe peripherals will affect the appearance of the building. For some buildings that require no rainwater pipes on the facade of the building, it is difficult to meet their design requirements.

In view of this, those skilled in the art urgently need to develop a kind of drainage system in the roof.

Contents of the invention

In order to overcome the deficiencies and defects existing in the existing metal roof drainage system, the present invention provides a novel metal roof siphon internal drainage system, which is a brand new organized drainage scheme.

The principle of the present invention is mainly that by setting an L-shaped retaining wall on the edge of the eaves, when it rains, the rainwater on the roof will converge to the vicinity of the eaves along with the slope of the roof. , under the action of the siphon rainwater bucket fairing, it will prevent the air from flowing into the rainwater bucket with the rainwater. The automatic water valve in the present invention will fill the rainwater pipe arranged on the roof when it rains (the automatic water valve is closed after the rainwater pipe is filled with water), and under the joint action of the siphon rainwater bucket and the automatic water valve, the rainwater bucket and There is no air mixed in the rainwater pipe, forming a closed space, and then producing a siphon effect, and under this effect, the rainwater gathered by the eaves is continuously pumped into the rainwater bucket under the action of atmospheric pressure, thereby achieving the purpose of drainage.

The invention provides a metal roof siphon internal drainage system, which includes a metal roof panel, a T-shaped support, a suspended ceiling, an I-shaped steel beam on the roof, and a thermal insulation cotton layer; the suspended ceiling is fastened to the I-shaped steel beam on the roof through screws, The T-shaped support is installed on the suspended ceiling, and the T-shaped support and the contacting ceiling are fastened and connected by screws. The metal roof panels of each layer are laid on the T-shaped support, and are connected by buckling at the lock head of the T-shaped support. , the insulating cotton layer is filled in the gap between the metal roof panel and the suspended ceiling; it also includes the outer retaining wall of the roof; the waterproof layer; the waterproof rubber strip; the rainwater pipe; the siphon rainwater bucket; the automatic water valve; the I-shaped support;
