Description

Technical Field

[0001] This utility model relates to the field of ventilated roofing technology, specifically a novel ventilated roofing structure. Background Technology

[0002] In hot-summer and warm-winter regions, traditional roof construction methods involve single-layer concrete slabs. Even with insulation or ventilation layers, heat transfer from the roof to the top floor cannot be prevented. This results in the temperature of rooms on the top floor being much higher than on other floors, increasing air conditioning and electricity loads. Traditional roof construction methods are not conducive to building energy conservation.

[0003] Therefore, those skilled in the art have provided novel ventilated roof structures to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a novel ventilated roof structure to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel ventilated roof structure includes a roof body, characterized in that a roof main body is fixedly connected to the top of the roof body, and multiple cast-in-place slabs are fixedly connected to the top of the roof main body. Ventilation ducts and vents are formed between the multiple cast-in-place slabs, and the middle of the cast-in-place slabs on both sides of the ventilation ducts is filled with thermal insulation material. Atomizing cooling mechanisms are provided on the cast-in-place slabs on both sides of the ventilation ducts to quickly remove heat from the roof, thereby achieving passive cooling, energy saving and emission reduction. Furthermore, this structure can be combined with the atomizing cooling mechanism to further effectively reduce heat, making it suitable for building roofs with special requirements.

[0007] As a further embodiment of this utility model: the ventilation duct is a Venturi channel that is wide at both ends and narrow in the middle, with the ventilation openings located at both ends of the ventilation duct and facing the windward side, so that the airflow enters the ventilation duct through the ventilation openings and accelerates its flow.

[0008] As a further aspect of this utility model: the atomizing cooling mechanism includes a conveying pipe, which is fixedly connected to one side of the cast-in-place slab. Multiple support blocks are snapped onto the outside of the conveying pipe. Multiple insertion holes are opened on the side surface of the conveying pipe, and connectors are fixedly connected inside each of the insertion holes. Atomizing nozzles are inserted into one side of each connector, and clamps are fitted onto the outside of the connectors. The introduction of the atomizing cooling mechanism provides an innovative cooling solution for the roof. By conveying cooling water or atomized liquid to each atomizing nozzle through the conveying pipe, the ambient temperature can be rapidly reduced. Furthermore, the even distribution of the atomizing nozzles ensures that the cooling effect covers the entire roof or a specific area, expanding the cooling area. Simultaneously, the insulation material set in the middle of the cast-in-place slab effectively improves the roof's insulation effect, reduces the impact of external temperature fluctuations on the indoor temperature, and maintains the stability of the indoor environment.

[0009] As a further embodiment of this utility model: a circulation pump is provided on one side of the conveying pipe, a water storage tank is provided at the bottom of the circulation pump, and a flow control valve is sleeved on the outside of the conveying pipe. The coordinated operation of the circulation pump, the conveying pipe, and the flow control valve ensures the stable operation of the cooling spray mechanism. By precisely controlling the flow rate, the flow control valve can also ensure that the flow speed of the water in the conveying pipe is stable, thereby avoiding the problem of uneven atomization caused by excessively fast or slow flow rates, and thus improving the cooling efficiency.

[0010] As a further improvement of this utility model: a cast-in-place reinforced concrete slab is provided at the bottom of the main roof structure, a fine aggregate concrete layer is provided on top of the cast-in-place reinforced concrete slab, a cement mortar leveling layer is provided on top of the fine aggregate concrete, and a base treatment agent is provided on the surface of the cement mortar leveling layer. The combined use of the cast-in-place reinforced concrete slab, the fine aggregate concrete layer, and the cement mortar leveling layer significantly improves the structural strength and stability of the roof, ensuring the safety of the building. At the same time, the impermeability of the fine aggregate concrete layer, the smoothness of the cement mortar leveling layer, and the sealing effect of the base treatment agent together constitute multiple waterproof barriers, effectively preventing water penetration and improving the waterproof performance of the roof.

[0011] As a further improvement of this utility model: a non-curing rubber asphalt waterproof coating is provided on top of the base treatment agent, and a self-adhesive polyester-based modified bitumen waterproof membrane is provided on top of the non-curing rubber asphalt waterproof coating. The combined use of the non-curing rubber asphalt waterproof coating and the self-adhesive polyester-based modified bitumen waterproof membrane forms multiple waterproof barriers. Both waterproof materials have excellent weather resistance and aging resistance, can resist the erosion of the external environment, prevent water penetration, and improve the waterproof performance of the roof.

[0012] As a further improvement of this utility model: the top of the self-adhesive polyester-modified bitumen waterproof membrane is provided with an extruded polystyrene foam board, the top of the extruded polystyrene foam board is provided with an isolation layer, the top of the isolation layer is provided with a fine aggregate concrete protective layer, the top of the fine aggregate concrete protective layer is provided with a ventilation channel, and both ends of the ventilation channel are provided with ventilation openings. The extruded polystyrene foam board has an extremely low thermal conductivity, which can effectively prevent heat transfer. The isolation layer is placed on top of the extruded polystyrene foam board, which can prevent the upper fine aggregate concrete protective layer from damaging the extruded polystyrene foam board during construction or use, and at the same time avoid both. The chemical reactions that may occur between the layers ensure the stability of the insulation layer. At the same time, the fine aggregate concrete protective layer protects the underlying waterproof and insulation layers from damage caused by external factors, such as ultraviolet radiation and external impacts. It also improves the durability and weather resistance of the roof. The ventilation duct is set on the fine aggregate concrete protective layer, and the vents at both ends allow air to circulate freely within the duct. Under sunlight, the roof temperature rises, and hot air rises into the ventilation duct and is discharged through the vents. At the same time, fresh, cool air enters the ventilation duct from the other end of the vent, forming air convection. This air convection can remove heat from the roof, reduce the roof temperature, and reduce the transfer of heat to the interior, thereby achieving a cooling effect.

[0013] As a further improvement of this utility model: the interior of the multiple cast-in-place slabs is provided with a cement mortar layer, and the interval between the multiple cast-in-place slabs is 3 meters. This arrangement provides a certain space for ventilation and promotes air circulation under the roof. On the other hand, when the temperature changes, the interval between the cast-in-place slabs can provide expansion and contraction space, avoiding cracks in the cast-in-place slabs due to thermal expansion and contraction, and ensuring the stability of the roof structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The introduction of the atomizing cooling mechanism provides an innovative cooling solution for the roof. Cooling water or atomized liquid is delivered to each atomizing nozzle through the delivery pipe, which can quickly reduce the temperature of the surrounding environment. The atomizing nozzles are evenly distributed to ensure that the cooling effect covers the entire roof or a specific area, thus expanding the cooling area. At the same time, the insulation material set in the middle of the cast slab effectively improves the insulation effect of the roof, reduces the impact of external temperature fluctuations on the indoor temperature, and maintains the stability of the indoor environment.

[0016] 2. The coordinated operation of components such as the circulating pump, delivery pipe, and flow control valve ensures the stable operation of the cooling spray mechanism. By precisely controlling the flow rate, the flow control valve can also ensure a stable flow speed of water in the delivery pipe, thereby avoiding uneven atomization caused by excessively fast or slow flow rates, and thus improving cooling efficiency.

[0017] 3. The 3-meter interval between multiple cast-in-place slabs provides space for ventilation, promoting air circulation under the roof. On the other hand, the interval between the slabs allows for expansion and contraction due to temperature changes, preventing cracks caused by thermal expansion and contraction and ensuring the stability of the roof structure.

[0018] In summary, ventilation ducts can quickly remove heat from the roof, achieving passive cooling, energy saving, and emission reduction. Furthermore, this structure can be combined with atomizing cooling mechanisms to further reduce heat effectively, making it suitable for building roofs with special needs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Reference Figure 1 - Figure 5This embodiment provides a novel ventilated roof structure, including a roof body 1. A roof main body 2 is fixedly connected to the top of the roof body 1. A sealing strip 3 is fixedly connected to the outside of the roof main body 2. Multiple cast-in-place slabs 4 are fixedly connected to the top of the roof main body 2. The middle of each cast-in-place slab 4 is filled with thermal insulation material 5. An atomizing cooling mechanism 6 is provided on one side of each cast-in-place slab 4. The atomizing cooling mechanism 6 includes a conveying pipe 601, which is fixedly connected to one side of the cast-in-place slab 4. Multiple support blocks 602 are snapped onto the outside of the conveying pipe 601. Multiple insertion holes 60 are opened on the side surface of the conveying pipe 601. 3. Each of the multiple insertion holes 603 has a connector 604 fixedly connected inside. Atomizing nozzles 605 are inserted into one side of the connector 604, and clamps 606 are sleeved on the outside of the connector 604. A circulation pump 7 is installed on one side of the delivery pipe 601, and a water storage tank 8 is installed at the bottom of the circulation pump 7. A flow control valve 9 is sleeved on the outside of the delivery pipe 601. The roof body 2 at the top of the roof 1 serves as the main roof load-bearing structure. The external sealing strip 3 can play a sealing role to prevent rainwater, dust, etc. from entering the house. The insulation material 5 installed in the middle of the multiple cast slabs 4 can effectively block In hot weather, the atomizing cooling mechanism 6 can be activated to transfer heat. Water in the water tank 8 is drawn by the circulating pump 7 and transported through the delivery pipe 601. The circulating pump 7 provides the power to circulate the water, ensuring it flows within the delivery pipe 601. Multiple insertion holes 603 are provided on the side surface of the delivery pipe 601. Inserts 604 are fixed within these holes, and atomizing nozzles 605 are inserted into one side of the inserts 604. After water reaches the inserts 604 through the delivery pipe 601, it enters the atomizing nozzles 605. Under these conditions, water is atomized into fine water droplets and sprayed out. The atomized water droplets absorb heat from the surrounding air and vaporize. The vaporization process is an endothermic process, which removes heat from the surrounding environment and achieves the purpose of lowering the roof temperature. Multiple atomizing nozzles 605 can cool the roof over a large area. The flow control valve 9 connected to the outside of the delivery pipe 601 can adjust the flow rate of water in the delivery pipe 601. According to the actual cooling needs, the amount of water sprayed by the atomizing nozzles 605 can be controlled by adjusting the flow control valve 9, thereby controlling the cooling effect and speed.

[0029] Example 2

[0030] Reference Figure 3 , Figure 6This embodiment is based on the previous embodiment, but differs in that the bottom of the roof body 2 is provided with a cast-in-place reinforced concrete slab 10, the top of the cast-in-place reinforced concrete slab 10 is provided with fine stone concrete 11, the top of the fine stone concrete 11 is provided with a cement mortar leveling layer 12, the surface of the cement mortar leveling layer 12 is provided with a base treatment agent 13, the top of the base treatment agent 13 is provided with a non-curing rubber asphalt waterproof coating 14, the top of the non-curing rubber asphalt waterproof coating 14 is provided with a self-adhesive polyester-based modified bitumen waterproof membrane 15, the top of the self-adhesive polyester-based modified bitumen waterproof membrane 15 is provided with an extruded polystyrene foam board 16, and the top of the extruded polystyrene foam board 16 is provided with an isolation layer 17. A fine aggregate concrete protective layer 18 is provided on top of the roof, and a ventilation duct 19 is provided on top of the fine aggregate concrete protective layer 18. Ventilation openings 20 are provided at both ends of the ventilation duct 19. A cement mortar layer 21 is provided inside the multiple cast-in-place slabs 4. The interval between the multiple cast-in-place slabs 4 is 3 meters. The cast-in-place reinforced concrete slab 10 has high strength and stability and can bear the weight of the upper structural layers and the external loads that the roof may bear. Fine aggregate concrete 11 is laid on the cast-in-place reinforced concrete slab 10. It can further level the foundation, enhance the integrity and waterproof performance of the roof, and also help to distribute the upper load and reduce the local pressure on the cast-in-place reinforced concrete slab 10. The cement mortar leveling layer 12 finely levels the surface of the fine aggregate concrete 11, making the surface smoother. The slippery surface creates favorable conditions for the subsequent waterproofing layer construction. The primer 13 is applied to the surface of the cement mortar leveling layer 12, enhancing the adhesion between the primer and the waterproofing layer. This allows the subsequently applied non-curing rubber asphalt waterproof coating 14 and self-adhesive polyester-modified asphalt waterproof membrane 15 to better adhere to the primer, forming a continuous and complete waterproofing layer. The extruded polystyrene foam board 16 has extremely low thermal conductivity, effectively preventing heat transfer. The isolation layer 17 is placed on top of the extruded polystyrene foam board 16, preventing damage to the extruded polystyrene foam board 16 during construction or use by the upper fine aggregate concrete protective layer 18, and also avoiding any potential chemical reactions between the two, ensuring... The insulation layer has stable performance, and the fine stone concrete protective layer 18 can protect the underlying waterproof and insulation layers from damage by external factors, such as ultraviolet radiation and external impact. It can also improve the durability and weather resistance of the roof. The ventilation duct 19 is set on the fine stone concrete protective layer 18. The ventilation duct 19 is a Venturi channel that is wide at both ends and narrow in the middle. The vents 20 at both ends allow air to circulate freely in the ventilation duct. Under sunlight, the roof temperature rises, and hot air rises into the ventilation duct and is discharged through the vents 20. At the same time, fresh cold air enters the ventilation duct from the other end of the vent 20, forming air convection. This air convection can remove heat from the roof, reduce the roof temperature, and reduce the transfer of heat to the room, thereby playing a role in cooling.
