Description

Technical Field

[0001] This utility model relates to the field of container house technology, and more specifically, to a drainage structure for a container house. Background Technology

[0002] With the widespread application of container houses in the construction industry, their waterproofing and drainage issues have received increasing attention. Traditional container house assembly structures have many shortcomings in drainage. For example, the drainage structure design is complex, construction is difficult, and drainage efficiency is low, easily leading to water accumulation on the roof of the container house. At the same time, the waterproof sealing performance of traditional assembly structures is poor, allowing rainwater to easily seep into the house through the seams, damaging not only items inside but also potentially corroding the container house structure, affecting its service life and safety. Therefore, there is an urgent need for an innovative drainage structure to solve these problems. Utility Model Content

[0003] In view of this, this utility model provides a drainage structure for container houses, which innovatively designs the drainage channel into a structure that integrates drainage and waterproofing functions. Through careful design of the drainage channel geometry and the rational use of sealing materials, the synergistic effect between the two is achieved, thereby simultaneously solving the two major technical problems of drainage efficiency and waterproof sealing, and successfully overcoming the bottleneck problems of complex structure and easy leakage in traditional container splicing drainage structures.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A drainage structure for a container house includes a drainage trough disposed around the perimeter of the top panel of the container house. Two adjacent container houses are joined together through the drainage trough to form a drainage channel. The drainage trough includes a first extension and a second extension. The first extension is connected to the top panel and extends downward at an angle, with its end forming a guide edge lower than the upper surface of the top panel. The second extension bends upward from the guide edge, with its top forming a water-blocking flange higher than the upper surface of the top panel. When two adjacent container houses are joined together, a top drainage gap is formed between the two corresponding water-blocking flanges. The top drainage gap is waterproofed by embedding a sealing gasket. The two first extensions and the corresponding second extensions respectively enclose the guide channel to form a drainage channel.

[0006] The core invention lies in the unique interlocking structure design of the drainage channels. This design not only smoothly forms drainage channels during the assembly of adjacent container houses, but also simultaneously achieves the two key functions of water diversion and waterproofing. Specifically, the ingenious combination of the first and second extensions gives the drainage channels the dual ability to divert rainwater and prevent backflow. The characteristic of the diversion edge being lower than the top surface of the roof provides a smooth path for rainwater to converge into the drainage channels; while the setting of the water-blocking flange being higher than the top surface of the roof greatly reduces the possibility of rainwater seeping through the splicing gaps. Therefore, after adjacent container houses are joined, the two drainage channels work together to precisely guide rainwater out along the pre-set diversion channels, effectively preventing water accumulation on the roof of the container houses. Furthermore, the top drainage gaps are filled and isolated with sealing gaskets, further reducing the possibility of rainwater seeping through the splicing gaps, effectively solving the problem of water leakage that is common in traditional container house splicing structures.

[0007] This design combines structural interlocking (i.e., the first and second extensions enclosing and forming a flow channel) with sealed interlocking (using a sealing gasket to fill the top drainage gap), significantly simplifying the construction process while effectively ensuring the efficiency and reliability of the drainage system. This innovative drainage structure is particularly suitable for applications involving the modular assembly of multiple containers.

[0008] Preferably, the axis of the guide channel forms a drainage slope with the horizontal plane.

[0009] Creating a drainage slope fully utilizes gravity, significantly increasing the flow velocity of rainwater within the drainage channels. Compared to a flat or poorly sloped system, a proper drainage slope ensures that rainwater drains quickly and smoothly along the channels, effectively reducing its residence time. This not only lowers the risk of blockage due to prolonged rainwater accumulation but also further improves the overall drainage efficiency of the system, guaranteeing the timeliness and effectiveness of drainage from the container house's roof. It effectively avoids a series of problems that can be caused by water accumulation, such as roof corrosion and leaks, thereby extending the lifespan of the container house and maintaining its structural integrity and performance.

[0010] Preferably, the sealing gasket is I-shaped, with symmetrical slots on both sides of the central rib and matching snap-fit ​​protrusions on the corresponding water-blocking flange.

[0011] The I-beam shaped sealing gasket structure boasts high stability, better adapting to relative displacement and vibration between adjacent container houses in various environments. Symmetrical grooves on both sides of the central rib engage with matching locking protrusions on the water-blocking flange, achieving precise positioning and tight engagement between the sealing gasket and the water-blocking flange. On one hand, this locking method enhances the installation firmness of the sealing gasket, preventing displacement or detachment during long-term use and ensuring consistently reliable waterproofing at the top drainage gap. On the other hand, the symmetrical structure ensures even stress distribution on the sealing gasket in all directions, further improving sealing performance and effectively preventing rainwater leakage from the top drainage gap. This provides reliable waterproof protection for the interior of the container house, preventing damage to items and the structure caused by rainwater seepage.

[0012] Preferably, the top of the water-blocking flange is provided with a waterproof cover, and the top arc surface of the cover covers the top drainage gap to form a double waterproof barrier.

[0013] The waterproof cover acts as an additional protective layer, further enhancing the waterproofing capability at the top drainage gaps. In severe weather conditions, such as heavy rain or strong winds, a single sealing gasket may be subjected to significant pressure and risk leakage. In such situations, the waterproof cover can absorb some of the impact force from rainwater, reducing the direct impact of rainwater on the sealing gasket and lowering the likelihood of gasket failure. Secondly, the curved design of the top conforms to fluid dynamics principles, helping to guide rainwater to slide off quickly and preventing rainwater accumulation at the top drainage gaps. This double waterproof barrier significantly improves the reliability of waterproofing, providing a higher level of waterproof protection for container houses, effectively resisting rainwater intrusion under various complex climatic conditions, and ensuring a dry and safe interior environment.

[0014] Preferably, the waterproof cover is inverted U-shaped and has an elastic clamping part. The water-blocking flange has symmetrical positioning grooves on opposite side walls. When two adjacent container houses are docked, the elastic clamping part is compressed and deformed to form an interference fit with the positioning groove.

[0015] The inverted U-shaped waterproof cover's ingenious design not only allows for a tight fit against the water-retaining flange, but its elastic clamping part also exhibits excellent adaptability and stability when engaging with the symmetrical positioning grooves on the opposite sidewalls of the water-retaining flange. During the docking of adjacent container houses, the elastic clamping part, after compression and deformation, forms an interference fit with the positioning grooves. This fit ensures the waterproof cover's stable installation. Even if the container house is subjected to external impact or experiences minor displacement due to long-term use, the waterproof cover will remain in the correct position and will not easily loosen or detach. Simultaneously, the interference fit further enhances the seal between the waterproof cover and the water-retaining flange, effectively preventing rainwater from seeping in through the gaps between them, further improving the waterproofing performance at the top drainage gaps, and providing a more reliable guarantee for the waterproofing effect of the container house.

[0016] Preferably, the first extension and the second extension are integrally formed.

[0017] The one-piece molding process eliminates the seams between the two components, thus avoiding potential leaks caused by seams. Compared to components connected by splicing, the one-piece structure is more robust and durable, able to withstand greater external forces without easily being damaged. During long-term use, the absence of seams eliminates concerns about the aging or detachment of sealant at seams affecting the overall performance of the drainage system. Furthermore, one-piece molding simplifies the manufacturing process, reduces assembly steps, lowers production costs, and increases efficiency, facilitating large-scale industrial production and enabling the wider application of this innovative drainage structure in the container housing sector.

[0018] Preferably, the first extension is integrally formed with the top plate.

[0019] The one-piece molding design significantly enhances the connection strength and integrity between the drainage channel and the roof panel. The absence of seams effectively prevents rainwater from leaking into the container house from the connection point. In practical use, the one-piece molding structure can better withstand various external forces and environmental factors, such as wind and temperature changes, and is less prone to cracking or loosening. Simultaneously, the one-piece molding process reduces the number of parts and assembly steps, lowers the difficulty of quality control during production, and improves product quality stability. This not only helps improve the overall quality and reliability of the container house but also facilitates later maintenance and repair work, reducing potential repair costs and workload.

[0020] Preferably, when two adjacent container houses are joined together, a side drainage gap is formed between the side panels of the corresponding two container houses, and the sealing gasket extends continuously from the top drainage gap to the side drainage gap.

[0021] This continuous design effectively solves the waterproofing problem at different parts of the container house's joints, forming a comprehensive, seamless waterproofing system. In practical use, rainwater may leak not only from the top drainage gaps but also seep into the interior of the house through the gaps between the side panels. The continuous extension of the sealing gasket ensures that both the top and side joints are effectively sealed. This not only improves the overall waterproofing performance of the container house but also prevents the spread of leaks caused by localized waterproofing failures. Furthermore, this integrated sealing design reduces the types and quantities of sealing materials used, lowers construction difficulty and costs, and also improves the stability and reliability of the sealing effect, providing more comprehensive and durable waterproof protection for the container house.

[0022] Preferably, the end of the drainage channel is provided with a transition section that connects to the side plate, and the transition section is provided with a downwardly inclined water guiding slope and a lateral drainage hole.

[0023] The downward-sloping guide ramp directs rainwater smoothly into the transition section, preventing water accumulation at the end of the drainage channel. Upon reaching the transition section, the ramp allows the rainwater to rush towards the side drain holes at a faster speed, further improving drainage efficiency. The side drain holes provide an additional drainage path, especially in situations with large water volumes in the drainage channel or blockages in the main drainage channel. These side drain holes can promptly drain accumulated water, preventing rainwater from flowing back into the container house. This transition section design optimizes the overall drainage system's performance, enhances the drainage structure's ability to handle various complex drainage conditions, ensures good drainage for the container house under different environmental conditions, and effectively protects the house structure and internal facilities from rainwater damage.

[0024] The advantages of this utility model compared to the prior art are:

[0025] This utility model discloses a drainage structure for container houses, which innovatively designs the drainage channel into a structure that integrates drainage and waterproofing functions. Through careful design of the drainage channel's geometry and the rational use of sealing materials, the two functions work synergistically, thereby simultaneously solving the two major technical challenges of drainage efficiency and waterproof sealing. This successfully overcomes the bottleneck problems of traditional container splicing drainage structures, such as structural complexity and easy leakage. Attached Figure Description

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0041] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0042] This embodiment provides a drainage structure for a container house, including a drainage trough 1 disposed around the periphery of the top plate 2 of the container house. Two adjacent container houses are connected to each other through the drainage trough 1 to form a drainage channel. The drainage trough 1 includes a first extension 11 and a second extension 12. The first extension 11 is connected to the top plate 2 and extends downward at an angle, with its end forming a guide edge 111 lower than the upper surface of the top plate 2. The second extension 12 bends upward from the guide edge 111 and its top end forms a water-blocking flange 121 higher than the upper surface of the top plate 2. When two adjacent container houses are connected, a top drainage gap 3 is formed between the two corresponding water-blocking flanges 121. The top drainage gap 3 is waterproofed by embedding a sealing gasket 5. The two first extensions 11 and the corresponding second extensions 12 respectively enclose and form a guide channel 4.

[0043] The core invention lies in the unique interlocking structure design of the drainage channel 1. This design not only smoothly forms a drainage channel during the assembly of adjacent container houses, but also simultaneously achieves the two key functions of water diversion and waterproofing. Specifically, the ingenious combination of the first extension 11 and the second extension 12 gives the drainage channel 1 the dual ability to divert rainwater and prevent backflow. The characteristic of the diversion edge 111 being lower than the upper surface of the top plate 2 provides a smooth path for rainwater to converge into the drainage channel 1; while the setting of the water-blocking flange 121 being higher than the upper surface of the top plate 2 greatly reduces the possibility of rainwater seeping through the splicing gaps. Therefore, after the adjacent container houses are connected, the two drainage channels 1 work together to precisely guide rainwater out along the pre-set diversion channel 4, effectively preventing water accumulation on the top of the container houses. Furthermore, the top drainage gap 3 is filled and isolated by the sealing gasket 5, further reducing the possibility of rainwater seeping through the splicing gaps, effectively solving the problem of water leakage that is common in traditional container house splicing structures.

[0044] This design combines structural fitting (i.e., the first extension 11 and the second extension 12 enclose and form the flow channel 4) with sealing fitting (using the sealing gasket 5 to fill the top drainage gap 3), which significantly simplifies the construction process while effectively ensuring the efficiency and reliability of the drainage system. This innovative drainage structure is particularly suitable for application scenarios involving the modular assembly of multiple containers.

[0045] In this embodiment, the axis of the guide channel 4 forms a drainage slope with the horizontal plane.

[0046] Creating a drainage slope fully utilizes gravity, significantly increasing the flow velocity of rainwater within the drainage channel 4. Compared to a flat or improperly sloped surface, a suitable drainage slope ensures that rainwater drains quickly and smoothly along the drainage channel 4, effectively reducing the time rainwater remains within it. This not only reduces the risk of blockage caused by prolonged rainwater accumulation but also further improves the overall drainage efficiency of the system, ensuring the timeliness and effectiveness of drainage from the container house's roof. It effectively avoids a series of problems that may be caused by water accumulation, such as corrosion and leakage of the roof panel 2, thereby extending the service life of the container house and maintaining its structural integrity and performance.

[0047] In this embodiment, the sealing gasket 5 is I-shaped, with symmetrical slots 52 on both sides of the central rib 51, and matching snap-fit ​​protrusions 123 on the corresponding water-blocking flange 121.

[0048] The I-shaped sealing gasket 5 boasts strong structural stability, enabling it to better adapt to relative displacement and vibration between adjacent container houses under varying environments. The symmetrically arranged grooves 52 on both sides of the central rib 51 engage with matching engagement protrusions 123 on the water-blocking flange 121, achieving precise positioning and tight engagement between the sealing gasket 5 and the water-blocking flange 121. On one hand, this engagement method enhances the installation firmness of the sealing gasket 5, preventing displacement or detachment during long-term use and ensuring consistently reliable waterproofing at the top drainage gap 3. On the other hand, the symmetrical structure ensures uniform stress distribution on the sealing gasket 5 in all directions, further improving sealing performance and effectively preventing rainwater leakage from the top drainage gap 3. This provides reliable waterproof protection for the interior of the container house, preventing damage to interior items and structure due to rainwater leakage.

[0049] In this embodiment, a waterproof cover 6 is provided on the top of the water-blocking flange 121, and the top arc surface of the cover covers the top drainage gap 3 to form a double waterproof barrier.

[0050] The waterproof cover 6, acting as an additional protective layer, further enhances the waterproofing capability at the top drainage gap 3. In severe weather conditions, such as heavy rain or strong winds, the individual sealing gasket 5 may be subjected to significant pressure and risk leakage. In such cases, the waterproof cover 6 can distribute some of the rainwater impact, reducing the direct impact of rainwater on the sealing gasket 5 and lowering the likelihood of its failure. Secondly, the curved design of the top conforms to fluid dynamics principles, helping to guide rainwater to slide down quickly and preventing rainwater accumulation at the top drainage gap 3. This double waterproof barrier significantly improves the reliability of waterproofing, providing a higher level of waterproof protection for the container house, effectively resisting rainwater intrusion under various complex climatic conditions, and ensuring a dry and safe interior environment.

[0051] In this embodiment, the waterproof cover 6 is inverted U-shaped and has an elastic clamping part 163. The water-blocking flange 121 has symmetrical positioning grooves 161 on opposite side walls. When two adjacent container houses are docked, the elastic clamping part 163 is compressed and deformed to form an interference fit with the positioning groove 161.

[0052] The inverted U-shaped waterproof cover 6 features a cleverly designed structure that not only fits tightly against the water-blocking flange 121, but also exhibits excellent adaptability and stability when its elastic clamping part 163 engages with the symmetrical positioning grooves 161 on the opposite sidewall of the water-blocking flange 121. During the docking of adjacent container houses, the elastic clamping part 163, after being compressed and deformed, forms an interference fit with the positioning grooves 161. This fit ensures the stable installation of the waterproof cover 6. Even if the container house is subjected to external impact or undergoes slight displacement due to long-term use, the waterproof cover 6 will always remain in the correct position and will not easily loosen or fall off. At the same time, the interference fit further enhances the sealing between the waterproof cover 6 and the water-blocking flange 121, effectively preventing rainwater from seeping in through the gaps between them, further improving the waterproof performance at the top drainage gap 3, and providing a more reliable guarantee for the waterproof effect of the container house.

[0053] In this embodiment, the first extension 11 and the second extension 12 are integrally formed.

[0054] The one-piece molding process eliminates the seams between the two components, thus avoiding potential leaks caused by seams. Compared to components connected by splicing, the one-piece structure is more robust and durable, able to withstand greater external forces without easily being damaged. During long-term use, the absence of seams eliminates concerns about the aging or detachment of sealant at seams affecting the overall performance of the drainage channel 1. Furthermore, one-piece molding simplifies the manufacturing process, reduces assembly steps, lowers production costs, and increases production efficiency, facilitating large-scale industrial production and enabling this innovative drainage structure to be more widely applied in the container housing sector.

[0055] In this embodiment, the first extension 11 is integrally formed with the top plate 2.

[0056] The one-piece molding design greatly enhances the connection strength and integrity between the drainage channel 1 and the roof panel 2. The absence of seams effectively prevents rainwater from leaking into the container house from the connection point. In practical use, the one-piece molding structure can better withstand various external forces and environmental factors, such as wind and temperature changes, and is less prone to cracking or loosening. Simultaneously, the one-piece molding process reduces the number of parts and assembly steps, lowers the difficulty of quality control during production, and improves product quality stability. This not only helps improve the overall quality and reliability of the container house but also facilitates later maintenance and repair work, reducing potential repair costs and workload.

[0057] In this embodiment, when two adjacent container houses are connected, a side drainage gap 6 is formed between the side panels of the corresponding two container houses, and the sealing gasket 5 extends continuously from the top drainage gap 3 to the side drainage gap 6.

[0058] This continuous design effectively solves the waterproofing problem at different parts of the container house's joints, forming a comprehensive and seamless waterproofing system. In actual use, rainwater may leak not only from the top drainage gap 3 but also seep into the interior of the house through the gaps between the side panels. The continuous extension of the sealing gasket 5 ensures that both the top and side joints are effectively sealed. This not only improves the overall waterproofing performance of the container house but also prevents the spread of leakage problems caused by localized waterproofing failures. Furthermore, this integrated sealing design reduces the types and quantities of sealing materials used, lowers construction difficulty and costs, and also improves the stability and reliability of the sealing effect, providing more comprehensive and durable waterproof protection for the container house.

[0059] In this embodiment, the end of the drainage channel 1 is provided with a transition section 13 that connects with the side plate. The transition section 13 is provided with a downwardly inclined water guiding surface 131 and a lateral drainage hole 132.

[0060] The downward-sloping guide slope 131 guides rainwater in the drainage trough 1 smoothly to the transition section 13, preventing rainwater from accumulating at the end of the drainage trough 1. When rainwater reaches the transition section 13, the design of the guide slope 131 allows the rainwater to rush towards the side drainage holes 132 at a relatively fast speed, further improving drainage efficiency. The side drainage holes 132 provide an additional drainage path for rainwater, especially in special circumstances such as a large volume of water in the drainage trough 1 or blockage of the main drainage channel. The side drainage holes 132 can promptly drain accumulated water, preventing rainwater from flowing back into the container house. This design of the transition section 13 optimizes the drainage performance of the entire drainage system, enhances the drainage structure's ability to cope with various complex drainage situations, ensures that the container house maintains good drainage under different environmental conditions, and effectively protects the house structure and internal facilities from rainwater damage.

[0061] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
