example 1

[0026] Example 1 There are train rails under the edge of the roof of a large railway station hall. In order to prevent the icicles formed under the gutter on the edge of the roof from causing harm to driving vehicles, a curved metal cover plate is used to prevent the icicles from falling. Electric heating system, the number of heating cables n 1 =2.

[0027] Step 1 Arrange the metal cover plate 1-1 on the building where the icicle falling hazard is likely to be formed on the lower edge of the gutter at the edge of the roof (see figure 2 , image 3 ), the heat tracing cable 2-1, the metal cover plate 1-1 is fixed on the building with the fixing bolt 3-1 penetrated into the bolt hole 4-1, forming an electric heat tracing system to prevent the hazard of falling icicles, Such as figure 1 . After the construction acceptance is passed, an electric heating system to prevent the hazards of falling icicles will be built.

[0028] Step 2 When the ice and snow melt in winter, the s...

example 2

[0029] Example 2 On the edge of the roof of an airport terminal building in a cold area, icicles are easy to form after snow in winter. Falling icicles may threaten the safety of passengers passing by and the facilities below. In order to solve the above problems, a broken-line metal cover plate is used to prevent the electric heating system from falling icicles. The number of heating cables is n 2 =3.

[0030] Step 1 Arrange metal cover plates 1-2 at the edge of the airport terminal roof in cold regions where icicles are likely to form (see Figure 5 , Image 6 ), heat tracing cables 2-2, use fixing bolts 3-2 to penetrate the bolt holes 4-2, and fix the metal cover plate 1-2 on the building to form an electric heat tracing system that prevents icicles from falling. Such as Figure 4 . After the construction acceptance is passed, an electric heating system to prevent the hazards of falling icicles will be built.

[0031] Step 2 When the ice and snow melt in winter, the s...

example 3

[0032] Example 3 The cantilevered edge of a civil building in a cold area is prone to icicles after snow in winter. Falling icicles may threaten the personal safety of passing residents. In order to solve the above problems, a U-shaped metal cover plate is used to prevent the electric heating system from falling icicles. The number of heating cables is n 3 =5.

[0033] Step 1 Arrange metal cover plates 1-3 on buildings where the overhanging edge of the rain-shielding overhang is likely to cause the hazard of falling icicles (see Figure 8 , Figure 9 ), heat tracing cables 2-3, use fixing bolts 3-3 to penetrate the bolt holes 4-3, and fix the metal cover plate 1-3 on the building to form an electric heat tracing system that prevents the hazard of falling icicles, Such as Figure 7 . After the construction acceptance is passed, an electric heating system to prevent the hazards of falling icicles will be built.

Abstract

The invention relates to an electric tracer heating system capable of preventing icicle falling hazards and an implementation method of the electric tracer heating system. The electric tracer heating system comprises metal cover plates, heat tracing cables, set bolts and bolt holes. The electric tracer heating system capable of preventing the icicle falling hazards is characterized in that the curved-line-shaped metal cover plates or the broken-line-shaped metal cover plates or the U-shaped metal cover plates and the heat tracing cables are arranged on a building where the icicle falling hazards are likely to be caused, the set bolts penetrate into the bolt holes to fix the metal cover plates on the building, and the electric tracer heating system capable of preventing the icicle falling hazards is formed. Icicles are made to be formed on the metal cover plates, when the icicles achieve a certain scale, the electric tracer heating system is turned on to melt the icicles, and the hazards caused by icicle falling can be prevented.

Description

technical field [0001] The invention relates to an electric heat tracing system and a realization method for preventing icicle falling hazards, which are applied to industrial and civil construction, stations, airports, canopies and other places in cold areas that need to prevent icicle falling hazards. Background technique [0002] On industrial and civil construction, stations, airports, canopies and other buildings in cold regions, icicles are easily formed by rain and snow in winter. Falling icicles will cause harm to people, vehicles and equipment below. [0003] The utility model patent "Gutter Snow Melting Plate (Authorized Notification No. CN 101851988 A)" involves an electric heat tracing snow melting device, but does not explain the problem of melting icicles. [0004] The utility model patent "Roof Ice and Snow Melting System (Authorized Notification No. CN 202359748 U)" involves an ice and snow melting electric heating system arranged in the gutter, which is arr...
