Description

Composite floor for heating

(1) technical field

The present invention relates to a kind of composite floor for heating, the composite floor for heating that particularly a kind of heat-conductive characteristic is good, deformation resistance is good.

(2) background technology

As everyone knows, China is the country of a forest reserves scarcity, and area of woods only accounts for 4% of whole world area of woods, and population accounts for 22% of whole world population.Along with fast development of national economy, the raising of people's lives standard and the intensification of realty industry, China increases year by year to the demand on various floors.Therefore, be to solve the contradiction of wood raw material imbalance between supply and demand, greatly develop with the using artificial fast-growing woods be one of Basic Ways.

Heating floor is one of artificial fast-growing woods application technology content high product that occurred in recent years.It is a kind ofly by being embedded in underfloor thermal source the floor to be heated to surface temperature 18-32 degree centigrade, reaches the floor of heating effect equably to indoor radiations heat energy.The low-temp radiation heating device is adopted on this floor, and the surface temperature height meets the air flowing law.Because head temperature is low, warmly begin to spread all over whole body from the underfooting, give the cool comfort of the warm head of pin, so heating floor also meets the theory " warm sufficient Liang Ding " of the traditional Chinese medical science.And compare with traditional heating system, geothermal heating system has been cancelled caliduct and the radiator in the room, is easier to the layout in room and attractive in appearance, science and save the energy more, and its application life, maintenance maintenance expense all are lower than the traditional heating mode, and be economical and practical.Therefore this heating system is admitted and is accepted by increasing people.

Be embedded in underfloor thermal source and be generally the water pipe that is connected with hot water, in recent years, also having occurred with heating cable or Electric radiant Heating Film is the heating floor of thermal source.Heat-conductive characteristic is good, thermal stability is good because the particularity of geothermal heating, heating floor must possess, good environmental protection, requirement that deformation resistance is good.The heating floor miscellaneous of Chu Xianing in the market, how with common wooden floor, consolidated floor, the floor that three-layer wood composite flooring and multi-layer solid wood composite floor etc. are used as heating, there are defectives such as coefficient of thermal conductivity is low, distortion is big, surface checking is many, contentedly the demand expanded day by day of heating floor.

(3) summary of the invention

The technical problem to be solved in the present invention is exactly the problem that existing heating floor coefficient of thermal conductivity is low, distortion is big, easily chap in the surface, a kind of composite floor for heating of new structure is provided, and this floor is a kind of aesthetic look of precious timber or bamboo and NEW TYPE OF COMPOSITE heating floor that composite floor board heat conduction is fast, heat stability is better than one of collecting.

Composite floor for heating of the present invention, comprise dash board, inferior dash board, central layer, base plate, be provided with horizontal thermal trough in the central layer, vertical thermal trough is set in the base plate, laterally thermal trough and the vertically mutual vertical and perforation of thermal trough, laterally be filled with heat-conducting medium in thermal trough and the vertical thermal trough, vertically thermal trough is two, distance between two vertical thermal troughs is 20-35mm, laterally thermal trough is many, distance between two adjacent horizontal thermal troughs is 25-40mm, and described heat-conducting medium is aluminium or copper.

Laterally thermal trough and the vertically interior heat-conducting medium of filling of thermal trough can be passed to time dash board, dash board, coefficient of thermal conductivity height fast and effectively with the thermal source heat that is arranged under the composite floor for heating.Simultaneously, this four layers composite construction makes that its distortion is less.

As improvement, dash board is timber or bamboo veneer, and inferior dash board is a fiberboard, and central layer, base plate are the fast growing wood plate.

Dash board adopts timber (especially precious timber, as seeds such as teak, beech, red sandalwoods) or bamboo veneer, and is not only attractive in appearance, and wear-resisting, distortion is littler.Inferior dash board is a fiberboard, mainly is because fiberboard can conduct heat and give dash board more equably more with spread heat.Central layer, base plate employing fast growing wood such as poplar, pine, China fir etc. are made.

As further improvement, the grain direction of central layer grain direction and dash board, base plate is perpendicular.The grain direction vertical interlaced of central layer grain direction and dash board, base plate can effectively increase the floor dimensional stability, has reduced bending, warpage and the flutes deform on floor.And preferably central layer is made by China fir, and base plate is made by poplar, and inferior dash board is a high density fiberboard.

For composite floor for heating recited above, laterally the thermal trough width is 0.5-2.5mm, preferred 0.5-1.5mm; Vertically the thermal trough width is 1-5mm, preferred 2-3.2mm.

For composite floor for heating recited above, dash board thickness is 1-3mm, preferred 2mm; Inferior dash board thickness is 2-4mm, preferred 3mm; Central layer thickness is 6-10mm, preferred 8mm; Base plate thickness is 1-3mm, preferred 2mm.

Beneficial effect of the present invention.This composite floor for heating is a primary raw material with timber (especially precious timber) or bamboo veneer, high density fiberboard, fast growing wood plate etc., the aesthetic look of collection timber (especially precious timber) or bamboo and composite floor board heat conduction are fast, heat stability is better than one, have rationally utilized timber (especially precious timber) or bamboo resource and artificial fast-growing woods resource; On structure design, taken into full account key elements such as heat transfer, distortion and cracking, made that its flexural deformation is little, heat conductivility is good.Therefore the present invention has boundless market development prospect.
