Problems solved by technology

This leads to an increase in the weight of the gutter of the light steel structure building. The weight of the gutter plus the weight of winter rain and snow can easily cause the roof to collapse
In some projects, in order to solve the self-weight problem of the gutter snow melting system, no cement backfill protective layer is added, so that the heating element will be exposed in the air, the snow melting effect is not ideal, and there are aging problems such as wind and sun in contact with the air, so the service life And the safety of electrical appliances has a great impact, and the existing gutter snow melting products have poor replaceability and complicated construction
When the snow melting project has problems such as aging or leakage, it is not easy to replace
The temperature control system of gutter snow melting products currently on the market is generally not perfect, requiring human participation, and cannot achieve intelligent automatic control

[0064] The heat source layer 2 is a resistive heating plate, and its preparation method is as follows:

[0065] 1) Mix 26 parts of dibutyl diformate, 12 parts of ethylenediamine pentahydrate and 58 parts of polytetrafluoroethylene resin in a proportion by weight, and then coat the template to form a base layer;

[0066] 2) Apply insulating varnish on the base layer and let it dry to form an insulating layer;

[0067] 3) Pour 7 parts of borax, 12 parts of insulating varnish, and 15 parts of graphite into ...

Embodiment 3

[0071] The material of the protective layer 1 is a polymer material, and its preparation method is as follows:

[0072] 1) by weight ratio, 50 parts of EPDM rubber and 15 parts of butyl rubber are masticated;

[0073] 2) Add 30 parts of carbon black, 20 parts of active rubber powder, 15 parts of naphthenic oil, 5 parts of zinc oxide, 5 parts of stearic acid and 5 parts of sulfur, fully mix, and then pour to the horizontal In the template, use it after cooling under pressure.

[0074] The heat source layer 2 is a resistive heating plate, and its preparation method is as follows:

[0075] 1) Mix 30 parts of dibutyl diformate, 14 parts of ethylenediamine pentahydrate and 60 parts of polytetrafluoroethylene resin in a proportion by weight, and then coat the template to form a base layer;

[0076] 2) Apply insulating varnish on the base layer and let it dry to form an insulating layer;

[0077] 3) Pour 11 parts of borax, 15 parts of insulating varnish, and 18 parts of graphite i...

Abstract

The invention relates to a gutter snow melting plate. The gutter snow melting plate is arranged in a gutter of a building with a lightweight steel structure. The gutter snow melting plate has the basic structure that a heat source layer (2) and a creepage protection layer (3) are arranged in a protective layer (1) and respectively connected with a temperature control box (4) through power lines. The gutter snow melting plate has the advantages of light weight, simple construction, convenient operation, energy saving and good snow melting effect, is replaceable, adopts the temperature control system for automatic control, and can effectively prevent snow water from flowing back.

Description

technical field [0001] The invention relates to a gutter snow-melting board, in particular to a building gutter snow-melting system with a light steel structure. Background technique [0002] In light steel structure industrial plant buildings, as the building area increases, the area of ​​the roof gutter is also larger. Ice and snow on the roof in winter accumulate in the gutter. If it is not melted and drained in time, it will not only easily crush the roof, but also cause damage to the internal machinery and equipment if it forms backflow. Therefore, the technical requirements for gutter snow melting are becoming more and more strict. Traditional gutter snow melting projects use heating cables or electric heating cables as heating elements, and cement backfill layers as protective layers. This causes the weight of the gutter of the light steel structure building to increase, and the weight of the gutter plus the weight of winter rain and snow can easily cause the roof t...
