Description
Technical field:
The present invention relates to a kind of heat-insulation and heat-preservation constructional materials, specifically a kind of light heat insulation ground heating brick.
Background technology:
The northern China building uses the heating system of ground heat pipe generally to be adopted now, and the trend that replaces the fin heating system is arranged very much.Yet the existing work progress of laying the ground heat pipe does not generally carry out according to the operating technology standard of national regulation, and its main cause one is that technical requirements height, difficulty are big, the 2nd, and cost height, material complexity.And present manufacture of materials producer is for catering to market, it is more and more simpler and easy to lay the ground hot material, the simplification that becomes of original very strict tecnical regulations, when laying the ground heat pipe, only lay very thin one deck foam heat-insulating film at basal layer, establish steel wire grid on it, re-lay the ground heat pipe, then, perfusion rubble and cement mortar are filled to fix and are promptly finished construction, so just several problems occurred: the one, and effect of heat insulation is poor, because generally the foam heat-insulating film that uses only has about 1 centimeter, foam is very soft again, after the ground heat pipe is spread, under the pressure of rubble and cement mortar, get the foam mould thinner, although one deck reflective membrane is arranged on the foam film, can reduce the radiation loss of heat energy, its thermal energy conduction loss can be very big; The 2nd, general work progress is directly to establish the ground heat pipe watering the build floor upper berth, because it is relatively poor to water the build floor levelness, most floors exist four jiaos of height, middle low phenomenon, therefore, the ground heat pipe of being laid is also uneven, and the inserts uneven distribution on it directly arrives the uniformity that influences radiating effect; The 3rd, the trend and the density of laying the ground heat pipe are random big, not only bondage underground heat pipe construction is wasted time and energy on the steel wire grid, and often cause ground temperature inequality, also can cause the situation of whole heating effect difference sometimes because certain single-column ground heat pipe laying length is unreasonable; The 4th, inserts weight is big, and general rubble of filling and cement mortar have about 120gk/m2, to the load bearing requirements height of floor; The 5th, after construction was finished, the ground heat pipe promptly was cast in together by rubble and cement mortar, in case occur that the ground heat pipe is damaged to be leaked, searched and repair very difficult, lost very big.
Use special-purpose geothermal energy brick to lay the ground hot pipe technique now and occur, but the geothermal energy brick that is adopted generally all has been to use heavier materials such as part cement or flyash to make, heat insulation effect is general, and weight is big.
Summary of the invention:
Problem based on the heat construction existence of above-mentioned laying ground, the present invention aims to provide a kind of light heat insulation ground heating paver that can solve problems such as effect of heat insulation is bad, inserts weight is big, the technical scheme of taking is: a kind of light heat insulation ground heating brick, it is protruding to be arranged with equidistant location above the tabular brick body of square in length and breadth, locate protruding height and spacing greater than ground heat pipe diameter, its raw material is formed and percentage by weight is: magnesia 40-48%, magnesium chloride 18-25%, sawdust 3-5%, rice husk 11-15%, land plaster 11-15%, calcium hydroxide 2-5%.
And preferred raw material forms and percentage by weight is: magnesia 46%, magnesium chloride 24%, sawdust 4%, rice husk 11%, land plaster 11%, calcium hydroxide 4%.
Normally used geothermal energy brick is generally that to be arranged with equidistant location above the square tabular brick body in length and breadth protruding, locatees protruding height and gap ratio ground heat pipe diameter is big, and locatees the protruding six rib types that are, so that the ground heat pipe is back and forth laid betwixt.
Raw materials such as employed magnesia, magnesium chloride, land plaster, calcium hydroxide were commercially available commerical grade during raw material was formed, and land plaster is commonly called as the plaster of paris, and calcium hydroxide is commonly called as hydrated lime.
The production method of light heat insulation ground heating brick and step:
1, supplementary materials such as magnesia, sawdust, rice husk, land plaster and calcium hydroxide is extracted in proportion, mix, fully stir with mixer;
2, extract magnesium chloride in proportion, add the thick slurry of suitable quantity of water furnishing;
3,1,2 liang of step raw material is mixed and fully stirring;
4, moulding is smash in the injection molding after shock;
5, demoulding, piling;
6, health is dried, and makes finished product.
The using method of light heat insulation ground heating brick:
1, at first laying light heat insulation ground heating brick on the super flat floor with cement mortar;
2, between the reference column of light heat insulation ground heating brick, move towards to lay the ground heat pipe by the ground heat pipe;
3, laying floor or floor tile on light heat insulation ground heating brick.
Beneficial effect:
1, good heat-insulation effect.Because sawdust, rice husk that the present invention adopts belong to lightweight, heat-barrier material, behind other raw and auxiliary materials stirrings, casting, chemical compositions such as magnesia, magnesium chloride, land plaster, calcium hydroxide react, sawdust, rice husk are condensed into firmer brick laying structure, thereby made a kind of lightweight and be heat the non-conductor material, therefore, can stop the conduction of heat well, the effect of heat insulation that plays.
2, in light weight, reduce the building carrying.Because materials such as the sawdust that light heat insulation ground heating brick is selected for use, rice husk, magnesia, magnesium chloride, land plaster, calcium hydroxide are light, the weight of laying after finishing only is 30gk/m
2About, lay the ground heat pipe well below conventional method and fill sandstone material 120gk/m
2Weight, therefore, can significantly reduce the carrying of building.
3, helping the ground heat pipe evenly lays.Because light heat insulation ground heating brick specification unanimity guaranteed that ground heat pipe levelness is higher, and the ground heat pipe is beneficial between reference column evenly distributed, therefore, the ground heat pipe is laid evenly, heat radiation is consistent, avoids occurring phenomenon uneven in temperature.
4, easy construction.Light heat insulation ground heating brick uniform specification of the present invention, generally using specification is 300 * 300 * 60mm, every brick face has 36 posts, between the reference column and aspect ratio ground heat pipe diameter is big, when laying the ground heat pipe, at first with the smooth ground that is laid on of light heat insulation ground heating brick, then, base area heat pipe trend, the ground heat pipe is embedded between the reference column, because reference column evenly distributes, the ground heat pipe can be arranged arbitrarily, very convenient, can greatly improve operating efficiency.
5, easy to maintenance.Because it is very smooth, firm to adopt light heat insulation ground heating brick to lay the ground heat pipe, its top re-lays floor tile or floating shop mode can be adopted in the floor, promptly is cast in together without cement mortar, in case the damaged leakage of ground heat pipe occurs, search and repair just very simple, can not cause very big loss.
