Description

Technical Field

[0001] This utility model relates to the field of building drainage and ventilation, specifically to a drainage and ventilation structure for building roof insulation layers based on the chimney effect. Background Technology

[0002] The chimney effect, also known as the stacking effect, refers to the phenomenon that air automatically flows upward within the vertical space of a building (such as a chimney, shaft, or exhaust pipe) when there is a temperature difference between the inside and outside of the building due to changes in air density with temperature.

[0003] In recent years, a three-layer waterproofing system has been widely implemented in building roof designs. This system involves two layers of waterproofing on the structural layer, followed by an insulation layer, and then a top layer of waterproofing on top of the insulation layer. According to relevant standards, ventilation pipes are installed within the insulation layer. Furthermore, to ensure that even if the top layer of waterproofing material is damaged, seepage can still drain through the insulation layer, preventing water accumulation and high water level osmotic pressure, additional drainage pipes are installed within the roof insulation layer.

[0004] Existing roof insulation layer ventilation and drainage systems typically use separate ventilation and drainage pipes. These two systems are independent of each other and have a single function, each only playing the role of ventilation or drainage, resulting in low system utilization.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a drainage and ventilation structure for building roof insulation layer based on the chimney effect, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A drainage and ventilation structure for a building roof insulation layer based on the chimney effect includes: a reinforced concrete roof structure layer, with a first concrete protective layer provided on the sidewall of the reinforced concrete roof structure layer; a waterproof protective layer located at the top of the first concrete protective layer, used to improve the waterproof and thermal insulation effect of the building; a rainwater pipe, interspersed in the first concrete protective layer and the waterproof protective layer, used to improve ventilation efficiency by utilizing the chimney effect; a ventilation and water collection component located at the top of the waterproof protective layer, with the bottom of the ventilation and water collection component penetrating the waterproof protective layer and the first concrete protective layer and connected to the rainwater pipe; and a rainwater collection port provided at the top of the rainwater pipe and at the top of the waterproof protective layer.

[0009] Furthermore, in order to achieve integrated waterproofing, seepage prevention, and thermal insulation, and to effectively prevent rainwater from the roof from seeping into the underlying structure, the waterproof protective layer includes a first waterproof layer placed on top of the first concrete protective layer, a roof insulation layer placed on top of the first waterproof layer, a slope-forming layer placed on top of the roof insulation layer, a leveling layer placed on top of the slope-forming layer, a second waterproof layer placed on top of the leveling layer, and a second concrete protective layer placed on top of the second waterproof layer; the ends of the first and second waterproof layers closest to the reinforced concrete structure of the roof enclose the roof insulation layer, the slope-forming layer, and the leveling layer.

[0010] Furthermore, to facilitate the removal of roof moisture and the collection and discharge of retained water, the venting and water collection assembly includes an vent pipe installed at the top of the waterproof protective layer, with an vent pipe cap at the top; a water collection pipe is horizontally installed between the first concrete protective layer and the waterproof protective layer, with the top of the water collection pipe connected to the bottom of the vent pipe, and one end of the water collection pipe connected to a rainwater pipe via an additional drainage pipe; a frustum-shaped pipe is installed at the top of the vent pipe cap, with a baffle plate at the top of the frustum-shaped pipe, and several vent holes are opened on the side wall of the frustum-shaped pipe; a perforated pipe is installed at the top of the baffle plate, with the bottom of the perforated pipe connected to the frustum-shaped pipe, and a mushroom head at the top of the perforated pipe.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) This utility model connects the exhaust pipe, the water collection pipe and the additional drainage pipe, realizing the function of collecting seepage water and draining the seepage water into the rainwater pipe.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0023] According to an embodiment of the present invention, a drainage and ventilation structure for a building roof insulation layer based on the chimney effect is provided.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4As shown, the roof insulation layer drainage and ventilation structure based on the chimney effect according to an embodiment of the present invention includes: a reinforced concrete roof structure layer 1, with a first concrete protective layer 2 provided on the side wall of the reinforced concrete roof structure layer 1; a waterproof protective layer 3, located at the top of the first concrete protective layer 2, used to improve the waterproof and insulation effect of the building; a rainwater pipe 4, interspersed on the first concrete protective layer 2 and the waterproof protective layer 3, used to improve ventilation efficiency by utilizing the chimney effect; a ventilation and water collection component 6, located at the top of the waterproof protective layer 3, and the bottom of the ventilation and water collection component 6 penetrates the waterproof protective layer 3 and the first concrete protective layer 2 and is connected to the rainwater pipe 4; a rainwater collection port 5 (i.e., roof rainwater collection port) is provided at the top of the rainwater pipe 4 and at the top of the waterproof protective layer 3.

[0025] The first concrete protective layer 2 consists of a 40-unit (e.g., millimeter, centimeter, etc.) thick fine stone concrete waterproof protective layer with steel mesh, a 1.5-unit thick cross-laminated self-adhesive waterproof membrane, a 30-unit thick C25 fine stone concrete protective layer, a 2% cement cinder slope, a 100-unit thick extruded polystyrene board insulation layer (with internal exhaust pipes), a 1.5-unit thick cross-laminated self-adhesive waterproof membrane, a 2mm thick non-curing rubber asphalt waterproof coating, and a reinforced concrete roof slab.

[0026] With the above solution, this utility model realizes the function of collecting seepage water and discharging it into the rainwater pipe 4 through the exhaust water collection component 6. At the same time, the connectivity of the rainwater pipe 4 forms a chimney effect, which significantly improves the exhaust efficiency of the insulation structure.

[0027] In one embodiment, the waterproof protective layer 3 includes a first waterproof layer 301 disposed on top of the first concrete protective layer 2, a roof insulation layer 302 disposed on top of the first waterproof layer 301, a slope-forming layer 303 (cement cinder slope-forming layer) disposed on top of the roof insulation layer 302, a leveling layer 304 (fine aggregate concrete leveling layer) disposed on top of the slope-forming layer 303, a second waterproof layer 305 disposed on top of the leveling layer 304, and a second concrete protective layer 306 (fine aggregate concrete leveling layer) disposed on top of the second waterproof layer 305. The first waterproof layer 301 and the second waterproof layer 305 wrap around the roof insulation layer 302, the slope layer 303 and the leveling layer 304 at the end near the reinforced concrete structure layer 1 of the roof. The first waterproof layer 301 and the second waterproof layer 305 adopt a combination of waterproof membrane and coating, or other common waterproof structures. By utilizing the multi-layer structure of the waterproof protective layer 3, waterproofing, seepage prevention and insulation are effectively integrated, effectively preventing rainwater from the roof from seeping into the lower structure and reducing the impact of temperature difference on the structural layer, thereby improving the overall durability and service life of the roof.

[0028] In one embodiment, the venting and water-collecting assembly 6 includes an vent pipe 601 disposed at the top of the waterproof protective layer 3, with an vent pipe cap 602 at the top of the vent pipe 601, and the vent pipe 601 and the vent pipe cap 602 connected by fasteners; a water-collecting pipe 603 is transversely disposed between the first concrete protective layer 2 and the waterproof protective layer 3, with the top of the water-collecting pipe 603 connected to the bottom end of the vent pipe 601, and one end of the water-collecting pipe 603 connected to the rainwater pipe 4 via an additional drainage pipe 604; the top of the vent pipe cap 602 is provided with... A frustum-shaped pipe 605 is provided with a baffle plate 606 at its top and several vent holes 607 are provided on the side wall of the frustum-shaped pipe 605. A perforated pipe 608 is provided at the top of the baffle plate 606, and the bottom end of the perforated pipe 608 is connected to the frustum-shaped pipe 605. A mushroom head 609 is provided at the top of the perforated pipe 608, thereby realizing the discharge of air moisture from the roof and the collection and discharge of retained water. Through the combined use of the vent holes 607, the perforated pipe 608, and the mushroom head 609, the exhaust efficiency is improved and rainwater backflow is prevented.

[0029] The collected water vapor and moisture are effectively guided through the water collection pipe 603, with some being discharged to the rainwater pipe 4 through the auxiliary drainage pipe 604. The gas is further discharged through the exhaust pipe 601, and then through the exhaust cap 602, the frustum-shaped pipe 605, the exhaust hole 607, the perforated pipe 608, and the mushroom head 609 in stages. The design of the exhaust passage ensures smooth exhaust, while the structure of the baffle plate 606 and the mushroom head 609 effectively prevents rainwater backflow and debris from entering the roof, avoiding roof bubbling, mold, and structural damage.

[0030] A PVC (polyvinyl chloride) vent pipe 601 with a diameter of 50 units is concealed on the water inlet pipe 603. The longitudinal and transverse spacing of the water inlet pipe 603 is less than 6m. A 5mm vent hole is made every 200mm, which also serves as a seepage collection hole. The vent pipe cap 602 has a diameter of 50 units and is made of stainless steel.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] The connectivity of the rainwater pipe 4 creates a chimney effect, improving indoor ventilation efficiency. The first waterproof layer 301 and the second waterproof layer 305 effectively prevent rainwater infiltration. The roof insulation layer 302 reduces heat loss and conduction, improving roof energy efficiency. The slope-forming layer 303, through its slope design, creates a drainage flow on the roof, preventing water accumulation. The leveling layer 304 provides a stable foundation for construction and the first and second waterproof layers 301 and 305, and corrects minor slopes.

[0033] Due to temperature changes, structural breathing, and construction moisture, water vapor or dampness generated in the roof structure will move to the top of the waterproof protective layer 3 between roof layers due to air pressure differences. The moisture is then directed outdoors through the vent pipe 601. The accumulated moisture is collected by the water collection pipe 603, guided through the additional drainage pipe 604, and finally discharged into the rainwater pipe 4, achieving timely removal of excess water from the roof.

[0034] The continuous waterproofing, insulation, and ventilation and water absorption process not only eliminates potential hazards such as structural damage, mold, hollowing, and corrosion, but also extends the overall service life and safety performance of the roof structure, achieving long-term protection and energy-saving goals for the roof structure.

[0035] In summary, this utility model connects the exhaust pipe 601, the water collection pipe 603, and the additional drainage pipe 604, realizing the function of collecting seepage water and draining it into the rainwater pipe 4. Simultaneously, the connectivity of the rainwater pipe 4 creates a chimney effect, significantly improving the exhaust efficiency of the insulation structure. By setting the first concrete protective layer 2 and the waterproof protective layer 3, waterproofing, seepage prevention, and insulation are effectively integrated, effectively preventing rainwater from seeping into the lower structure and reducing the impact of temperature differences on the structural layers, thereby improving the overall durability and service life of the roof. By setting the exhaust and water collection component 6, the exhaust of roof moisture and the collection and discharge of retained water are realized. The combined use of the exhaust hole 607, the perforated pipe 608, and the mushroom head 609 improves exhaust efficiency and prevents rainwater backflow.
