Description
Technical field
The utility model relates to heat-insulating technique field in construction work, specifically a kind of building roof heat-proof device.
Background technology
At present, Roofing brick conventional in construction work unit can not play heat insulation effect, and summer, owing to being subject to the irradiation of hot sunlight, temperature can raise, and especially for staying in high-rise resident, it within doors can be scorching hard to bear.
Present roof temperature is approximately 40 degrees Celsius, and traditional mode can not solve effective heat-insulating problem.The heat insulation mode had at present mainly contains: convection-plate is heat insulation, material is heat insulation and water circulation is heat insulation.Except water circulation is heat insulation, other heat insulation mode is not satisfactory.Although convection-plate is heat insulation achieve blocking-up heat trnasfer in theory, in actual applications, undue dependence external ventilation concurrent condition.And on roof, convection-plate, because parapet wall is to the inhibition of wind, makes the air in convection-plate interlayer, can not flow away smoothly.The results showed, have a large amount of hot gas to pile up in convection-plate, thus hot gas still has very strong transmission of heat by contact rate to roof.And the technology of the heat insulation current employing of material is, use porous material, as pearl salt porous ceramics, the cavity mostly flowed downward by obstruction hot air and huge specific heat capacity heat accumulation, slowed down the rising principle of temperature, carry out heat insulation.But the objective physical fact is, general house, before at 9 in the morning, is inevitably heated to 50-60 degrees Celsius, is just slow down heat transfer speed theoretically, still has a large amount of heat to infiltrate within doors.And although the heat insulation effect of water circulation is better, power consumption is comparatively large, and is limited to the reason of building structure condition, and general house is also not suitable for promoting.
Utility model content
The purpose of this utility model is to provide a kind of building roof heat-proof device, by hindering heat radiation, absorbs the heat of the sun, directly for thermal convection current provides stable power, thus hinders the aerial transmission of heat.
The technical solution of the utility model is as follows:
A kind of building roof heat-proof device, include upper and lower plate, it is characterized in that: described lower plate is provided with cavity, the bottom surface of lower plate is provided with the multiple through holes leading to described cavity, described upper plate is fixedly connected in described lower plate, and the middle part of upper plate is provided with the opening be connected with described cavity, and the bottom surface of described cavity is placed with dividing plate, between the bottom surface of described dividing plate and the bottom surface of described cavity, there is gap, between the edge, surrounding of dividing plate upper surface and the interior edge of described opening, there is gap; Surrounding bottom described lower plate is fixedly connected with multiple support respectively, has gap between adjacent two supports.
Described building roof heat-proof device, is characterized in that: the area of described cavity bottom surface is greater than the area of described opening.
Described building roof heat-proof device, is characterized in that: the area of described dividing plate is slightly less than the area of described cavity bottom surface, is greater than the area of described opening.
Described building roof heat-proof device, is characterized in that: the bottom of described multiple support is fixedly connected with base plate.
The beneficial effects of the utility model:
The utility model is simple, efficient, do not limit by concrete material, energy conversion number of times is few, and do not rely on outside concurrent condition, to various types of roof, there is general compliance, convection current effect of heat insulation of the present utility model is much larger than general heat insulating tile, do not need in this process to consume any other energy (only using the heat coming from the sun) simultaneously, and its structure has conjugation to heat leak, namely heat is higher, the heat insulation energy of convection current is stronger, ensure that the roof insulating effect under any condition.

Detailed description of the invention
See Fig. 1,2, a kind of building roof heat-proof device, include upper and lower plate 1,2, lower plate 2 is provided with cavity 3, and the bottom surface of lower plate 2 is provided with the multiple through holes 4 leading to cavity 3, and upper plate 1 is fixedly connected in lower plate 2, the middle part of upper plate 1 is provided with the opening 5 be connected with cavity 3, the bottom surface of cavity 3 is placed with dividing plate 6, between the bottom surface of dividing plate 6 and the bottom surface of cavity 3, there is gap, between the edge, surrounding of dividing plate 6 upper surface and the interior edge of opening 5, there is gap; Surrounding bottom lower plate 2 is fixedly connected with multiple support 7 respectively, has gap between adjacent two supports.
In the utility model, the area of cavity 3 bottom surface is greater than the area of opening 5; The area of dividing plate 6 is slightly less than the area of cavity 3 bottom surface, is greater than the area of opening 5; The bottom of multiple support 7 is fixedly connected with base plate 8.
Below in conjunction with accompanying drawing, the utility model is further described:
Dividing plate 6 intercepts direct solar radiation, and provides thermal source for the air in cavity 3, provides condition for hot air rises to flow away.The effect of multiple through hole 4 makes that air is through enters cavity 3, thus cold air is effectively filled enter cavity 3.The effect of lower plate 2 and multiple support 7 is: intercept the radiation of air indirect thermal, and stops too much hot air accumulation to contact with roof.Multiple support 7 for supporting lower plate 2, and forms non-closed support, and its effect is: maintain admission space.
When solar radiation dividing plate 6 surperficial, dividing plate 6 stop sunlight through and heated, the heat altogether with it of the air in cavity 3.Because buoyancy strengthens, hot air overflows from the gap between edge in the edge, surrounding and opening 5 of dividing plate 6 upper surface, and the inside of cavity 3 forms negative pressure.Now, cool ambient air enters from the gap between adjacent two supports, and it is inner to pour into cavity 3 from multiple through hole 4, and then is heated the above-mentioned circulation of maintenance by dividing plate 6.Its objective is: use dividing plate 6, make air layering, when maximum heat leak rate, also can ensure that hot air does not contact with roof, this, compared with the vertical convection structure announced in other patents, is characterized in: can ensure hot gas all the time not with house top contact, and stop its indirect heat radiation, and air flow process is short, does not rely on the extra powers such as blower fan.
