Building gutters play an important role in the diversion of rain and ice and melt water falling on the roof, and are an important part of the roof drain system. However, in the northern part of my country, the timely discharge of ice and melt water from the gutters is even more important during the periods of the autumn-winter and winter-spring seasons, as it directly affects the reliability of the roof drain system, building safety and personal safety.

Drain System Engineers collect rainwater and melt snow and preserve them in orderly drainage channels. In parts of the northern part of my country, when the weather is cold, rainy and snowy, because of the large temperature difference between day and night, the sun is enough at noon, the snow on the roof begins to melt and the snow slowly drains. Flows into the roof chute The remains of melted ice and snow will gradually freeze, forming an ice dam in the chute, making it difficult to rank the subsequent melted ice and snow. Chute.

In order to ensure smooth water removal from ice and snow melting in the roof chute, roof leakage and structural safety caused by freezing and thawing of the ice trough and gutter, the current rainwater drainage structure has a roof trough. The melting system, which is due to the electricity distribution system, the snow melting system and the control system.

Electric power distribution system: mainly includes junction boxes and distribution cables that provide 220 V, 50Hz power for the snow melting system and is the power source for the system.

Snow melting system: Mainly includes electric heating cables, matching connecting accessories and fasteners. The heating cable uses electricity as energy to convert heat to heat to melt ice and snow in the gutters and gutters. It is an important part of the snow melting system. Melting system; the connecting elements themselves are insulating materials for the connection between the heating cable and the distribution cable, between the heating cable and the heating cable; the fastener serves to fix the heating cable in the chute.

Control system: mainly includes control system and sensors.

As the gutter is a conduit for rainwater, as well as melting ice and snow, the heating cable should be laid along the bottom of the gutter, and the number of cables to be laid depends on local climatic conditions and the width of the gutter. The distance between heating cables in some areas of the northern part of my country can be 100-200mm. Combined with environmental conditions, the distance in areas with large dimensions can be smaller, and the distance in areas with low dimensions can be longer. Each rainwater bucket in the trough has an independent connecting pipe. These rainwater buckets and connecting pipes are also heating elements that cannot be ignored. These parts and chute can be combined into one system when designed. The specific method may be to prevent the heating cable from entering the rainwater bucket mouth into the rainwater connecting pipe, and the number of heating cables installed in the connecting pipe depends on the minimum ambient temperature.

The gutter snow melting system has become a new design area faced by the designers of the water supply and drainage systems and the electrical engineering of the buildings. Its working interface and distribution of responsibilities have not yet been clarified. In terms of engineering design, the roof snow melting system can also be widely used in stations, airports, industrial enterprises, large public buildings, sports facilities, etc. D., which should gradually become important design configurations to improve the level of building safety.
