Description
Technical field
The present invention relates to the floor heating field of engineering technology, also relate to the applied technical field of carbon fiber heating cable.
Background technology
The Along with people's living standard improve constantly the continuous lifting with environmental consciousness, adopt the carbon fiber heating cable to be accepted by people as heater element.
And floor heating also is the technical method that people give indoor large-area heating, and the warm or hot-water heating of electricity is adopted in existing floor heating mostly.
Hot-water heating is at the floor pavement water pipe, makes the recirculated water laggard oral siphon that heats up through electric heater or gas heater.Water floor heating major defect has: 1, road formula coil pipe; Complex-shaped, pipeline is longer, and the variation of supply water temperature can produce calcium ions and magnesium ions dirt (central heating may bring mud rust deposite, bacterium algae etc.); Pipeline scale 1mm every year on average, and the thick incrustation scale of this 1mm can cause water temperature to descend about 6 ℃.In general water floor heating operation needed additional payment in the time of 2～4 years, please professional floor heating clean company, cleaned the elimination incrustation scale with professional equipment, not so directly influenced the heating effect, even caused the floor heating vessel embolization.The place that water quality is bad, wash number are more.Even water quality is good, but the anaerobic bacteria flora in the pipeline also can be bred generation wall dirt voluntarily.2, water floor heating normal preheating time more than 3 hours, ground reached evenly more than at least 4 hours, was fit to run without interruption for a long time, was not suitable for short-term and used, and also was not suitable for repeatedly switch and used.3, be difficult to accomplish locellus control, no matter the heating of several room, whole system and boiler all must move, and so can waste to some extent.4, need 24 hours round-the-clock opening cold winter, in a single day because close, water pipe freezes, the bursting by freezing of water knockout drum parts possibility, and influence is used.5, the toilet coil pipe is limited, because scope little (such as reserving toilet seat, bathtub, the following mouth of a river etc.), therefore trouble are laid in the toilet.6, because temperature is more than 55 ℃ in the water pipe, and the coil pipe spacing is bigger again, so the cold and hot some temperature difference can reach about 10 ℃, the non-homogeneous stress of thermal expansion is bigger, so ground concrete thickness meeting cracking below 3cm, so cement will be thickeied, therefore cost increases.7, boiler needs maintenance, and the critical piece of its bulk life time 10 ~ 15 years, boiler internal is changed (at one's own expense) about 5 years.Be 6 ~ 8 years the service life of water collecting and diversifying device, and the joint of water collecting and diversifying device is because the phenomenons such as causing the gas leakage of leaking easily of expanding with heat and contract with cold.
The metal electric floor heating is at floor pavement metal heating cable, energising back heating, and the resistance value of metal heating cable is changeable, so can do the heating cable of growth, also can make shortly, is easy to be fit to various room areas and uses.Its major defect is: 1,, also be called kelvin effect because the metal heating conductor is easy to generate Kelvin effect when indirect current, so its heating efficiency is low, and power consumption.2, long more metal heating cable, its operating current is just big more, and according to physics, the power frequency magnetic field intensity of its generation is just big more.Even the metal heating cable can coat screen layer, but screen layer can shield power-frequency electric field strength, can't shield power frequency magnetic field intensity.
Summary of the invention
The present invention is the construction method that proposes a kind of not only safety but also energy-conservation carbon fiber underground heat.
The present invention includes following steps:
1) warming plate that on indoor cement blank ground, tiles;
2) on warming plate, lay reflectance coating;
3) on warming plate, excavate counterbore, in counterbore, be bumped into terminal box;
4) with the power line thereto;
5) the carbon fiber heating cable is arranged in above the reflectance coating, and the two ends of every carbon fiber heating cable are penetrated the access hole of terminal box respectively, and link to each other with power line;
6) with the PUR sealed terminal box;
7) lay the cement protective layer.
Easy construction of the present invention, quick when being used for household underground heat with the carbon fiber heating cable, has more advantage than metal heating cable:
1, carbon fiber is unlike the such easy oxidation of metal, so longer service life.
2, nonmetallic carbon fiber wire does not have Kelvin effect; So the heating efficiency of carbon fiber heating cable is a little more than the metal heating cable; If future, large tracts of land was popularized household carbon fiber heating cable, reduce and use the metal heating cable, then can practice thrift much electricity after the accumulation.
3, the idle phenomenon in all fronts that can avoid place's metal heating cable to break down and cause.Because the length of every group of carbon fiber heating cable normally has only about 10～15m, parallel connection is used mutually, even one bad, also can not produce very big influence to system.
4,, reduce the healthy injury of indoor human body because every carbon fiber heating cable length is shorter, and operating current is also less, and the power frequency magnetic field intensity of generation is also little.
For maintenance from now on, also can terminal box be arranged in indoor center, so that search after installing for a long time.
For carbon fiber heating cable and the reflectance coating that prevents to have laid in the work progress is shifted, the present invention is positioned at the carbon fiber heating cable on the warming plate through the card pin in said step 5).
In order to improve the thermal efficiency, also be beneficial to energy savings, in said step 5), the distance between the adjacent carbon fiber heating cable of laying is 5～20cm.
Distance between the preferable carbon fiber heating cable is 8～10cm.The also construction of convenient follow-up cement protective layer, the operative employee can stand in its pin between the adjacent carbon fiber heating cable, and can directly not trample on the carbon fiber heating cable.
Prevent that in order to improve the heat insulating ability of floor heating, also to be beneficial to the carbon fiber heating cable from exempting from destruction, the thickness of cement protective layer of the present invention is 20～35mm.
The specific embodiment
Construction procedure is following:
1, indoor cement blank ground is cleared up.
2, the warming plate that on indoor cement blank ground, tiles.
3, on warming plate, lay reflectance coating.
4, in room area, secure a position near the geometric center, on the warming plate of this position, excavate counterbore, in counterbore, be bumped into terminal box.When being bumped into terminal box, the plane exceeds below the warming plate 2cm on the terminal box.
5,, add the power line gauge tap of protective casing outside the power line outside terminal box until the wall limit with the power line thereto.
6, press the size of careat; With every carbon fiber heating cable is the center with the terminal box; Be the shape of blooming to connecting up by certain rule all around; Each root carbon fiber heating cable is arranged in above the reflectance coating, and the two ends of the carbon fiber heating cable of every parallel connection are penetrated the access hole of terminal box respectively, and links to each other with power line.Distance between the adjacent carbon fiber heating cable is 8～20cm.Through bail each carbon fiber heating cable is positioned on the warming plate then.
7,, make its insulation and waterproof with the PUR sealed terminal box.
8, completely spread the cement protective layer that thickness is 20～35mm.
