Building roof structure

The present invention discloses a building roof structure formed by a skeleton, hollow assemblies, a waterproof layer and a heat insulation plate. The hollow assemblies are installed on the skeleton, the waterproof layer is paved on the hollow assemblies and the heat insulation plate is disposed above the waterproof layer. Hot air rising up inside the building and heat accumulated on the roof by being exposed to sun can all be circulated out through cooling spaces formed by the hollow assemblies, which achieves the cooling effect of natural air circulation to reduce temperature inside the building without using external fans or air drafting equipment. Therefore, the green building concept that saves energy and reduces CO2 emission is complied with, thereby improving the living quality of building.

BACKGROUND OF THE INVENTION

a) Field of the Invention

The present invention relates to a building roof structure, and more particularly to an air permeation roof that utilizes an effect of natural air circulation to save energy and reduce temperature inside the building and of the roof.

b) Description of the Prior Art

An ordinary tin house can be built up quickly and therefore is applied to a gathering place, a resident house, a factory, a warehouse or a market that is built temporally. However, under direct exposure to sun, temperature inside the tin house can increase quickly. Therefore, a ceiling fan will be added under the roof of the tin house to reduce primarily the temperature inside the tin house.

Nevertheless, adding the ceiling fan under the roof of the tin house is very dangerous, not implemented easily and not pretty. Furthermore, as the ceiling fan is suspended high, objects or persons underneath the ceiling fan can be injured easily if the ceiling fan drops accidentally. In addition, according to the physical phenomenon that hot air rises up and cold air descends, hot air will be concentrated at a top inside the tin house. As the ceiling fan is installed in proximity to the top inside the tin house, when the ceiling fan is turned on, hot air at the top of the tin house will be blown downward, which only results in convection of the hot air inside the tin house and allows the people inside the tin house to feel like staying in an oven, without actually expelling out the hot air.

Accordingly, there are vendors who have designed a way of adding plural rooftop ventilation fans outside the tin house to achieve the air circulation effect by connecting indoor air with outdoor air. This method utilizes primarily natural wind to drive the ventilation fans, such that an air drafting effect can be formed by the ventilation fans and hot air inside the tin house can be expelled out. Besides that, air convection can be formed inside and outside the tin house.

However, this method can only activate the ventilation fans to rotate if there is natural wind. On the contrary, if there is no natural wind, then the hot air in the tin house is still not able to be expelled out effectively and quickly. In addition, as fan blades of the ventilation fans are not the air drafting blades, the air drafting efficiency is not high.

In addition, the relative terms such as “one,” “two,” “above” used in the specification are for convenience of description only and are not used to limit the range of implementation of the present invention. The change in or adjustment of the relative relationships is also considered as being within the range of implementation of the present invention, if there is no physical change in the technical means.

Referring toFIG. 1andFIG. 2, it shows a first embodiment of the present invention. The present invention provides an air permeation roof of a building, and this air permeation roof1is formed primarily by a skeleton10, hollow assemblies12, a waterproof layer14and a heat insulation plate16. The skeleton10is built on a top of the building and is installed with plural hollow assemblies12. In the first embodiment, the hollow assembly12is formed by plural baffles120, and the baffles120form plural cooling spaces122for air circulation. The waterproof layer14and the heat insulation plate16that are paved orderly on the hollow assembly12insulate primarily most of the heat energy, and also prevent from penetration of rain water or water sprinkled for reducing temperature. It is worth of mentioning that in addition to a roof tile, the heat insulation plate16can also utilize a solar panel that is now usually applied in a green building (in this embodiment, an ordinary roof tile is used as an example). On the other hand, as the hollow assembly12is formed by the baffles120, the way of arranging the baffles120and the orientation thereof can be changed depending upon the actual requirement to improve the entire air convection, thereby achieving the best air circulation effect. Moreover, to avoid birds building nests in the cooling spaces122, isolation nets18are installed at air openings and can also keep foreign objects from entering into the cooling spaces122.

As shown inFIG. 2AandFIG. 2B, to cope with a rainy day and avoid a problem that results from accumulation of the rain water on the roof, in this embodiment, a tail end of the heat insulation plate16is installed at least with a flow deflector160. The flow deflector160is formed with plural drain holes1602to expel the rain water downward, thereby achieving the purpose of expelling water on the roof effectively. On the other hand, to achieve the purpose of recycling the water resource, the skeleton10is installed with a collecting trough17that corresponds to the flow deflector160and collects the rain water; whereas, the rain water in the collecting trough17can be stored and used to cool down the heat insulation plate16in the future. In order to sprinkle the rain water on the heat insulation plate16successfully, a center of the air permeation roof, according to the present invention, is equipped with a ridge11; whereas, the ridge11is installed with a water sprinkler19. Therefore, through the water sprinkler19, the rain water collected can be sprinkled on the heat insulation plate16that results in high temperature by heat. This not only achieves the purpose of sprinkling the water to reduce temperature, but also complies with the intention of recycling the water resource, allowing the present invention to be provided with the green building concept that saves energy and reduces CO2emission. In addition to the abovementioned structures, a tail end of the flow deflector160can be installed with plural illuminating lamps1604to increase a visual sense of beauty by projecting light of the illuminating lamps1604on the dripping water jets.

Referring toFIG. 3andFIG. 4, it shows a second embodiment of the present invention. The difference from the abovementioned first embodiment lies in that the hollow assembly12ais formed primarily by plural hollow bricks120awith a cooling space122a, and the hollow bricks120aare arranged beneath the waterproof layer14ain an array. As the hollow bricks120acan use existing specifications and products on the markets, the hollow assembly12acan be formed by installing the hollow bricks420aone by one directly in an array to reduce time of construction. The hollow assembly12ais the same as that of the first embodiment, but the only difference is that the heat insulation plate16ais a solar panel, which will not be described further.

As shown inFIG. 5, it shows a third embodiment of the present invention, wherein the hollow assembly12bis formed primarily by plural long hollow bricks120bwith a cooling space122b, and the long hollow bricks120bare arranged side-by-side above the waterproof layer14b.

This kind of hollow assembly12bis made specifically according to length or width of the roof and the long hollow bricks120bare installed side-by-side on the roof. Therefore, the quantity of long hollow bricks120bcan be reduced significantly, yet still achieving the better air circulation effect. As the hollow assembly12bis the same as that of the first embodiment, further description is not disclosed.

In the present invention, the hollow assembly12is installed on the skeleton10. However, to achieve the best indoor air circulation effect, the skeleton10and the hollow assembly12are connected (whereas, they are not connected in the second and third embodiment). Referring toFIG. 7, it can be clearly understood that the baffles120are all built on the skeleton10, enabling the cooling spaces122among the baffles120to connect with an indoor space. Therefore, when indoor hot air rises up, the hot air will enter into the cooling spaces122directly, and then indoor temperature will be reduced by natural air circulation. It is worth of mentioning that when sun irradiates stronger, the heat convection of air will be more explicit and the rate of air circulation will be higher. In other words, the hotter the weather is, the better the indoor air circulation effect will be. Therefore, the indoor air can be circulated by a natural energy source, without using electricity to dissipate heat.

Besides that,FIG. 6discloses clearly the connection among the bricks. Herein, a hollow brick120awith plural cooling spaces122ais used as an example. In order to fix the hollow bricks120atogether, a side of each hollow brick120ais formed with a connecting unit1202ato combine and fix with the connecting unit1202aon the other hollow brick120a. Therefore, this can facilitate fixing upon assembling the hollow bricks120a, and the hollow bricks120acan be positioned, as well.

Accordingly, following functions can be acquired from the abovementioned structures:1. The effect of natural air circulation can be utilized to reduce temperature of the air permeation roof.2. As there is no need to use the external fans or air drafting equipment, it is not necessary to maintain the external fans or air drafting equipment constantly, thereby reducing the cost of related equipment.3. As indoor temperature is reduced using the effect of natural air circulation provided by the hollow assembly, the green building concept that saves energy and reduces CO2emission is complied with, thereby improving the living quality of building.
