Description

Technical Field

[0001] This utility model relates to the field of building waterproofing technology, specifically to a roof drainage and ventilation structure. Background Technology

[0002] Currently, during roof waterproofing construction, a waterproof layer is typically installed on the roof, along with drainage channels or outlets. Several vertical vent pipes connected to these drainage channels or outlets are also installed to expel moisture from the structural layer. However, in the roof structure, the drainage channels / outlets and vertical vent pipes form the only ventilation and drainage channel. These channels and outlets are prone to partial blockage, losing their ventilation function. Therefore, over long-term use, if the drainage channels or outlets become blocked, the vertical vent pipes will be unable to drain the accumulated water from the roof structure, leading to a gradual worsening of roof seepage problems year after year. Utility Model Content

[0017] The following detailed explanation illustrates the specific implementation methods:

[0018] like Figures 1 to 3 As shown:

[0019] A roof drainage and ventilation structure includes a roof 1 and a parapet wall 2. The parapet wall 2 is arranged around the roof 1. The parapet wall 2 and the roof 1 constitute the basic structure of the roof. It also includes a drainage and ventilation component and a waterproof component. The waterproof component is attached to the surface of the roof 1 and the parapet wall 2 to waterproof the roof 1 and the parapet wall 2. The drainage and ventilation component is installed on the surface of the waterproof component to drain the water accumulated on the roof 1 and the water vapor that may exist inside the roof 1.

[0020] The drainage and venting assembly includes a drainage module and a venting module. The drainage module is installed on the roof 1 for drainage and venting of the roof 1, and the venting module is installed on the parapet wall 2 for auxiliary venting of the roof 1.

[0021] The drainage module is installed above the waterproof components on the roof 1 through a cement mortar layer 4, allowing the drainage module to be embedded within the cement mortar layer 4 and thus fixed to the roof 1. Simultaneously, the cement mortar layer 4 provides protection and enclosure for the drainage module. The drainage module includes several guide channels 6 and several drainage and ventilation mechanisms. The guide channels 6 are crisscrossed and evenly installed above the roof 1, ensuring interconnection and forming a drainage network for the roof 1. Drainage pipes 11, passing through the parapet wall 2, are installed at the ends of the guide channels 6 and are connected to the guide channels 6. Water in the guide channels 6 can be discharged through the drainage pipes 11. When there is no water residue in the drainage pipes 11, external vapor can enter through each drainage pipe 11. The water flows into the guide channel 6 to assist in venting steam. The guide channel 6 is equipped with a drainage and venting mechanism for water and steam permeability. The drainage and venting mechanism includes a permeable plate 7 and permeable columns 8. The permeable plate 7 covers the guide channel 6, and several permeable columns 8 are evenly arranged on the permeable plate 7. The surface of the permeable columns 8 is flush with the surface of the cement mortar layer 4, so that the water accumulated on the surface and inside of the cement mortar layer 4 can be guided into the permeable plate 7 through the permeable columns 8, and then drip into the guide channel 6 through the permeable plate 7. The water vapor in the guide channel 6 and the cement mortar layer 4 can also be discharged to the outside through the permeable plate 7 and the permeable columns 8. Through the synergistic effect of each permeable column 8, multiple venting channels are formed, which can efficiently vent steam from the roof 1.

[0022] The venting module is installed on the surface of the waterproof components of the parapet wall 2 through the cement mortar layer 4. The venting module is embedded in the cement mortar layer 4. The venting module includes several venting channels 10 and several drainage and venting mechanisms. Each venting channel 10 is evenly installed on the surface of the parapet wall 2. The surface of the drainage and venting mechanism at the venting module is flush with the cement mortar layer 4 at the parapet wall 2. The venting channel 10 is connected to the guide channel 6, so that water vapor from the guide channel 6 and the roof 1 can enter the venting channel 10. The top of the venting channel 10 is separated from the eaves 3 at the top of the parapet wall 2 to form a permeable channel 5. Then, the water vapor in the venting channel 10 can be discharged to the outside through the permeable channel 5 and the drainage and venting mechanism at the venting channel 10.

[0023] Both the permeable plate 7 and the permeable column 8 are made of sintered material, which creates fine through holes in the permeable plate 7 and the permeable column 8. While allowing water and air to pass through, they also have a certain strength to support items on the roof 1.

[0024] The permeable columns 8 of the drainage module are connected by fiber rope nets 9, which are embedded in the cement mortar layer 4. The limiting rope nets can guide the water in the cement mortar layer 4 to the permeable columns 8, which facilitates the permeability of the cement mortar layer 4 to water and air.

[0025] The waterproofing components include a waterproof membrane 12 and a waterproof resin layer 13. The waterproof membrane 12 is laid on the surface of the roof 1 and the parapet wall 2, and the waterproof resin layer 13 is coated on the surface of the waterproof membrane 12 to form a waterproof structure of the roof 1 and reduce water seepage into the roof 1.

[0026] The specific implementation process is as follows:

[0027] When using this roof drainage and ventilation structure, firstly, waterproof membrane 12 and waterproof resin layer 13 are laid on the surfaces of roof 1 and parapet wall 2. Then, the drainage and ventilation components are installed on the surface of the waterproof resin layer 13. Next, cement mortar layer 4 is laid on the surfaces of roof 1 and parapet wall 2, so that the surface of cement mortar layer 4 is flush with the surface of the permeable column 8 of the drainage and ventilation components. This completes the construction of the roof drainage and ventilation structure. If there is water accumulation on roof 1, the water seeps into the permeable column 8, which guides the water to the permeable plate 7. The permeability of the structure allows water to seep into the drainage channel 6, which then drains the water out of the roof 1 through the drain pipe 11. The water seeps into the cement mortar layer 4 and is guided to the permeable columns 8 via the fiber rope net 9. After the water in the roof 1 is drained, water vapor remains in the cement mortar layer 4. Some of the water vapor is discharged to the outside under the guidance of the permeable columns 8, while some water vapor is guided to the steam pipes through the drainage pipes and discharged into the permeable channel 5 between the permeable channel 5 and the top eaves 3 of the parapet wall 2, and then discharged to the outside.

[0028] This roof drainage and ventilation structure can drain and vent air from the roof 1 through drainage modules and ventilation modules. The drainage and ventilation mechanisms at the drainage and ventilation modules facilitate the entry of accumulated water into the guide channel 6, and then discharge it from the roof 1. At the same time, it can facilitate the dissipation of water vapor in the drainage channel, reduce the water vapor content of the roof 1, and thus improve the leak-proof performance of the roof 1.
