Description

Technical Field

[0001] This invention relates to the technical field of polar architecture, and in particular to an enclosure joint structure for polar architecture and its construction method. Background Technology

[0002] The harsh climate of polar regions limits the effective construction window throughout the year, typically representing only a small percentage of the normal construction cycle. This makes it difficult to allow sufficient time for fine-tuning the on-site installation of structural modules, unlike other construction projects. This presents significant challenges to construction precision control and exacerbates the problem of error accumulation. While the main structure and enclosure components are mostly prefabricated in domestic factories, their rapid temperature drops upon arrival at the polar site alter the physical properties of the materials, causing significant temperature deformation and further amplifying processing deviations. Furthermore, the main and enclosure modules are made of different materials with inherently different coefficients of thermal expansion. Under the extreme temperature variations of the polar seasons, these modules are prone to incompatible deformation, creating additional stress.

[0003] Existing building envelope designs generally lack adaptive measures for the junctions of structural modules, failing to fully consider the combined effects of construction errors, processing tolerances, and thermal deformation, resulting in insufficient stability of the envelope system during long-term use. In actual engineering projects, glass panels in the envelope structure often crack due to continuous compressive stress. Furthermore, due to the unique polar environment, replacing broken glass is extremely complex, requiring coordination of transportation, personnel, and equipment resources, resulting in lengthy replacement cycles, severely disrupting the normal functioning of the building, and significantly increasing subsequent operation and maintenance costs and difficulties. In extreme environments, the building envelope system must simultaneously meet basic performance requirements such as waterproofing and thermal insulation, while effectively accommodating various deformations and errors; existing technical solutions struggle to meet these critical requirements. Summary of the Invention

[0004] The purpose of this invention is to provide an enclosure joint structure for polar architecture and its construction method to solve at least some of the problems mentioned above.

[0005] The first aspect of the present invention provides an enclosure joint structure for polar architecture, including a main structure, an enclosure structure, an elastic thermal insulation structure, and a waterproof structure. An installation gap is formed between adjacent main structures. Adjacent enclosure structures are respectively connected to the main structures. The elastic thermal insulation structure fills the installation gap and is connected to the enclosure structure. The waterproof structure is expandably and sealably connected between the elastic thermal insulation structure and the adjacent enclosure structure.

[0006] Furthermore, the waterproof structure includes a first decorative profile, a second decorative profile, and a first sealing strip. The first decorative profile and the second decorative profile are respectively sealed to the corresponding enclosure structure. The first sealing strip is telescopically connected between the first decorative profile and the second decorative profile. The first sealing strip, the elastic thermal insulation structure, and the adjacent enclosure structure form a first waterproof pressure equalization cavity.

[0007] Furthermore, the first sealing strip includes an inner connecting portion, an outer connecting portion, and an elastic tension portion. The two inner connecting portions of the elastic tension portion are respectively connected to the first connecting groove of the first decorative profile and the second connecting groove of the second decorative profile.

[0008] Furthermore, the opening direction of the first connecting groove is opposite to the opening direction of the third connecting groove, and the opening direction of the second connecting groove is opposite to the opening direction of the fourth connecting groove.

[0009] Furthermore, the waterproof structure also includes a second sealing strip. The first decorative profile is provided with a first extension plate extending toward the second decorative profile, and the second decorative profile is provided with a second extension plate extending toward the first decorative profile. The first extension plate and the second extension plate are offset from each other. One end of the second sealing strip is connected to the first extension plate, and the other end of the second sealing strip is sealed against the second extension plate. A third waterproof pressure equalization cavity is formed between the first decorative profile, the second decorative profile, the first sealing strip, and the second sealing strip.

[0010] Furthermore, the waterproof structure also includes a third sealing strip, the first decorative profile is also provided with a fifth connecting groove, the second decorative profile is also provided with a sixth connecting groove, the two third sealing strips are respectively accommodated in the fifth connecting groove and the sixth connecting groove, and the two third sealing strips are respectively sealed and connected to the corresponding enclosure structure.

The inner side of the main insulation layer is connected to the main structure, the glass veneer layer is disposed on the outer side of the main protective layer, and the elastic insulation structure is disposed between the two main insulation layers.

[0012] Furthermore, the main insulation layer includes a main insulation board and polyurethane thermal break keel for supporting the main insulation board, and the elastic insulation structure is disposed between the two polyurethane thermal break keels.

[0013] Furthermore, the enclosure joint structure also includes a fixing plate and a sealant. The fixing plate is used to press the inner side of the waterproof structure to the enclosure structure, and the sealant is used to seal the joint between the outer side of the enclosure structure and the waterproof structure.

[0014] A second aspect of the present invention provides a construction method for the joints of the enclosure of a base building, comprising: A prefabricated modular main structure and enclosure structure, wherein the main structure is connected to the enclosure structure; Adjacent main structures are spliced ​​together, forming installation gaps between adjacent main structures; Fill the installation gap with the elastic insulation structure and connect the elastic insulation structure to the enclosure structure; The waterproof structure is retractable and sealed outside the elastic insulation structure and enclosure structure.

For those skilled in the art, the specific meaning of the terms in this invention can be understood according to the specific circumstances.

[0020] See Figure 1-9 This embodiment discloses an enclosure joint structure for a polar building, including a main structure 10, an enclosure structure 20, an elastic thermal insulation structure 30, and a waterproof structure 40. An installation gap 11 is formed between adjacent main structures 10. Adjacent enclosure structures 20 are respectively connected to the main structures 10. The elastic thermal insulation structure 30 fills the outside of the installation gap 11 and is connected to the enclosure structure 20. The waterproof structure 40 is expandably and sealably connected between the elastic thermal insulation structure 30 and the adjacent enclosure structure 20.

[0021] In polar architecture, the main structure (10) refers to the load-bearing frame of the building, which is generally constructed using a modular prefabrication method to adapt to short construction windows and extreme environments.

[0022] The main function of the building envelope 20 is to separate indoor and outdoor spaces, resist the intrusion of external environmental factors, and provide functions such as heat preservation, heat insulation, and waterproofing.

[0023] Specifically, the enclosure structure 20 includes a main insulation layer 21 and a glass veneer layer 22. The inner side of the main insulation layer 21 is connected to the main structure 10, the glass veneer layer 22 is located on the outer side of the main protective layer, and the elastic insulation structure 30 is located between the two main insulation layers 21.

[0024] The main insulation layer 21 is the core insulation component of the building envelope 20, primarily responsible for providing the thermal insulation performance required by the building structure. The glass cladding layer 22 is the outer layer of the building envelope 20, mainly serving to decorate and protect the main insulation layer 21, as well as provide lighting or views. The glass cladding layer 22 typically uses multi-layer insulated glass or vacuum glass.

[0025] By placing the elastic insulation structure 30 between the two main insulation layers 21, the insulation performance of the enclosure structure 20 itself is effectively utilized, forming a more continuous and efficient insulation system. This arrangement allows the elastic insulation structure 30 to work better with the main insulation layers 21 to jointly resist the extreme cold of polar regions. The elastic insulation structure 30 in this location needs to possess good compression resilience, durability, and insulation performance to accommodate minor displacements between the main structures 10 and maintain the continuity of insulation at the gaps.

[0026] Furthermore, the main insulation layer 21 includes a main insulation board 211 and polyurethane thermal break keel 212 for supporting the main insulation board 211, and the elastic insulation structure 30 is disposed between the two polyurethane thermal break keels 212.

[0027] The main insulation layer 21 of this design is made of 0.8mm fluorocarbon roller-coated steel plate + 50mm rock wool board + 150mm polyurethane + 0.5mm polyester roller-coated steel plate. The polyurethane material in the polyurethane thermal break keel 212 has a low thermal conductivity, thus its use as a keel effectively blocks heat conduction paths and significantly reduces thermal bridging. The polyurethane thermal break keel 212 is typically in strip or profile shape and is fixed to the main structure 10 by bolts, adhesives, or other connection methods, providing a stable mounting base and support for the main insulation board 211.

[0028] The elastic insulation structure 30 is a material or component with certain elasticity and thermal insulation properties, used to fill the gaps between building components to accommodate relative displacement of the components while providing thermal insulation. In this solution, the elastic insulation structure 30 is an integrated elastic polyurethane rock wool panel.

[0029] In this embodiment, the polar building envelope joint structure utilizes an elastic insulation structure 30 to fill the installation gaps 11 between adjacent main structures 10. Simultaneously, a retractable, sealing waterproof structure 40 connects the elastic insulation structure 30 and the envelope structure 20. This allows the entire envelope system to effectively accommodate the relative displacement and deformation of the main structure 10 and the envelope structure 20 caused by construction, processing errors, and temperature changes in the polar environment. Therefore, this structure helps prevent damage to the envelope system components due to compression, ensuring the airtightness, watertightness, and thermal insulation performance of the building envelope system under extreme climatic conditions, thereby reducing the difficulty and cost of later maintenance. See Figure 3 The waterproof structure 40 includes a first decorative profile 41, a second decorative profile 42, and a first sealing strip 43. The first decorative profile 41 and the second decorative profile 42 are respectively sealed to the corresponding enclosure structure 20. The first sealing strip 43 is telescopically connected between the first decorative profile 41 and the second decorative profile 42. The first sealing strip 43, the elastic thermal insulation structure 30, and the adjacent enclosure structure 20 form a first waterproof pressure equalization cavity 401.

[0030] This solution constructs a waterproof system with good flexibility and adaptability, effectively coping with the structural thermal expansion and contraction caused by the drastic temperature differences in the polar environment, and avoiding the cracking or failure problems caused by stress concentration in traditional sealing materials. More importantly, by forming a first waterproof pressure equalization cavity 401 between the first sealing strip 43, the elastic insulation structure 30, and the adjacent enclosure structure 20, the driving force of external wind pressure on rainwater penetration is effectively reduced by utilizing the principle of wind pressure balance. This significantly improves the waterproof performance and durability of the enclosure joints, ensuring the long-term stable operation of polar buildings under harsh climatic conditions and the comfort of the internal environment.

[0031] See Figure 4-6 The first sealing strip 43 includes an inner connecting portion 431, an outer connecting portion 432, and an elastic tension portion 433. The two inner connecting portions 431 of the elastic tension portion 433 are respectively connected to the first connecting groove 411 of the first decorative profile 41 and the second connecting groove 421 of the second decorative profile 42. The two outer connecting portions 432 are respectively connected to the third connecting groove 412 of the first decorative profile 41 and the fourth connecting groove 422 of the second decorative profile 42. The inner connecting portion 431, the outer connecting portion 432, the elastic tension portion 433, the first decorative profile 41, and the second decorative profile 42 form a second waterproof pressure equalization cavity 402.

[0032] The elastic stretching part 433 is a part of the first sealing strip 43 specifically designed to absorb and adapt to relative motion caused by temperature changes, structural displacement, etc. It typically adopts a wavy, U-shaped, V-shaped, X-shaped or other deformable geometric shape to provide sufficient elastic deformation space to ensure the continuity and effectiveness of the seal.

[0033] The inner connecting part 431 and the outer connecting part 432 are both provided with first teeth, and the first connecting groove 411, the second connecting groove 421, the third connecting groove 412 and the fourth connecting groove 422 are all provided with second teeth. The first teeth are pressed against the second teeth to achieve a better sealing effect.

[0034] By designing the first sealing strip 43 to include an inner connecting portion 431, an outer connecting portion 432, and an elastic tension portion 433, and connecting the inner connecting portion 431 and the outer connecting portion 432 to the first connecting groove 411, the second connecting groove 421, the third connecting groove 412, and the fourth connecting groove 422 of the first decorative profile 41 respectively, a more robust and redundant sealing connection is constructed. This dual-point connection method significantly enhances the fixing strength and anti-detachment ability between the first sealing strip 43 and the decorative profile, effectively resisting stress concentration and displacement caused by drastic temperature changes and wind pressure fluctuations in polar environments. More importantly, this structure ingeniously forms a second waterproof pressure equalization cavity 402 between the inner connecting portion 431, the outer connecting portion 432, and the elastic tension portion 433 of the first sealing strip 43 and the second decorative profile 42. This second waterproof pressure equalization cavity 402, together with the existing first waterproof pressure equalization cavity 401, constitutes a dual pressure equalization waterproof system. When external wind pressure acts on the joint, the pressure can enter the second pressure equalization chamber through the external gaps, causing the pressure inside and outside the chamber to tend to balance. This significantly reduces the direct damaging force of wind pressure on the sealing strip and effectively prevents rainwater or snowmelt from seeping in under wind pressure. Even if there are minor defects in the external sealing layer, the second pressure equalization chamber can act as a buffer layer to further prevent moisture from entering the interior. Through its internal pressure equalization mechanism, the infiltrated moisture is discharged, thereby greatly improving the waterproof reliability, durability, and wind pressure resistance of the entire enclosure joint structure, ensuring the long-term stable operation of polar buildings in extreme environments.

[0035] Furthermore, the opening direction of the first connecting groove 411 is opposite to the opening direction of the third connecting groove 412, and the opening direction of the second connecting groove 421 is opposite to the opening direction of the fourth connecting groove 422.

[0036] By setting the opening direction of the first connecting groove 411 to be opposite to that of the third connecting groove 412, and setting the opening direction of the second connecting groove 421 to be opposite to that of the fourth connecting groove 422, the inner connecting portion 431 and the outer connecting portion 432 of the first sealing strip 43 can be snapped into or fixed to the corresponding decorative profile in different directions during installation. This design creates differentiated and multidirectional constraints on the first decorative profile 41 and the second decorative profile 42 for the first sealing strip 43, effectively enhancing the connection stability between the first sealing strip 43 and the decorative profile. Under the complex conditions of extreme temperature changes, wind pressure loads, and minor structural displacements faced by polar buildings, this interlocking connection method can significantly reduce the risk of the first sealing strip 43 falling off the connecting groove, thereby ensuring the long-term sealing reliability of the waterproof structure 40, avoiding water ingress or a decrease in thermal insulation performance inside the enclosure structure 20 due to sealing failure, and thus improving the durability and safety of the entire polar building enclosure joint structure.

[0037] In one embodiment, the waterproof structure 40 further includes a second sealing strip 44. The first decorative profile 41 is provided with a first extension plate 414 extending toward the second decorative profile 42, and the second decorative profile 42 is provided with a second extension plate 424 extending toward the first decorative profile 41. The first extension plate 414 and the second extension plate 424 are offset from each other. One end of the second sealing strip 44 is connected to the first extension plate 414, and the other end of the second sealing strip 44 is sealed against the second extension plate 424. A third waterproof pressure equalization cavity 403 is formed between the first decorative profile 41, the second decorative profile 42, the first sealing strip 43, and the second sealing strip 44.

[0038] The first extension plate 414 and the second extension plate 424 are structural extensions of the first and second facing profiles 41 and 42, respectively, and are integrally formed with the facing profiles. These extension plates are designed to provide a stable mounting base and sealing contact surface for the second sealing strip 44. The staggered arrangement of the first extension plate 414 and the second extension plate 424, rather than being directly aligned, forms a meandering path. This staggered layout not only increases the length and difficulty of moisture penetration but also creates the necessary space for the installation and effective sealing of the second sealing strip 44. One end of the second sealing strip 44 is firmly connected to the first extension plate 414 by mechanical fixing, bonding, or embedding, ensuring its stable position. The other end is sealed against the second extension plate 424 in a compressible and expandable manner, forming a tight contact and thus establishing an effective sealing line between the two. The third waterproof pressure equalization chamber 403 is a closed space formed by the first decorative profile 41, the second decorative profile 42, the first sealing strip 43, and the second sealing strip 44. This chamber further reduces the driving force for water vapor penetration by balancing the pressure with the external environment, thereby enhancing the overall waterproof performance.

[0039] By introducing a second sealing strip 44 and the staggered fit of the first extension plate 414 and the second extension plate 424, this application further constructs a third waterproof pressure equalization cavity 403 based on the original waterproof structure 40. This multi-seal and multi-level pressure equalization cavity design significantly enhances the waterproof performance of the enclosure joints. When external moisture attempts to penetrate the first sealing strip 43, the third waterproof pressure equalization cavity 403 can effectively block further penetration of moisture through an internal pressure balance mechanism. At the same time, the second sealing strip 44, as an independent sealing barrier, provides an additional line of defense, ensuring the dryness of the interior of the enclosure structure 20 even if the first seal is affected under extreme conditions. This effectively solves the potential penetration risk of a single waterproof layer in polar environments, greatly improving the overall waterproof reliability, durability, and thermal insulation stability of the building envelope structure 20.

[0040] In one embodiment, the waterproof structure 40 further includes a third sealing strip 45, the first decorative profile 41 is provided with a fifth connecting groove 413, and the second decorative profile 42 is provided with a sixth connecting groove 423. The two third sealing strips 45 are respectively accommodated in the fifth connecting groove 413 and the sixth connecting groove 423, and the two third sealing strips 45 are respectively sealed and connected to the corresponding enclosure structure 20. By providing the fifth connecting groove 413 and the sixth connecting groove 423 on the first decorative profile 41 and the second decorative profile 42, and accommodating the third sealing strips 45, this application adds an independent sealing barrier to the original waterproof structure 40.

[0041] In this design, the first decorative profile 41 and the second decorative profile 42 are made of aluminum alloy, and the first sealing strip 43, the second sealing strip 44 and the third sealing strip 45 are all low-temperature resistant EPDM rubber strips.

[0042] In one embodiment, the enclosure joint structure further includes a fixing plate 50 and a sealant 60. The fixing plate 50 is used to press the inner side of the waterproof structure 40 to the enclosure structure 20, and the sealant 60 is used to seal the joint between the enclosure structure 20 and the outer side of the waterproof structure 40.

[0043] The fixed pressure plate 50 provides continuous mechanical clamping force, firmly pressing the waterproof structure 40 to the enclosure structure 20, thereby ensuring the structural stability of the connection and the tightness of the initial seal, effectively resisting loosening that may be caused by external wind loads and structural displacement. Simultaneously, the sealant 60 fills any tiny gaps that the fixed pressure plate 50 cannot completely eliminate, forming a flexible and continuous waterproof barrier, further preventing the penetration of moisture, air, and cold air. This dual protection mechanism, combining mechanical pressing and flexible sealing, significantly improves the long-term sealing performance and durability of the enclosure joints in harsh environments such as polar cold and large temperature differences, effectively avoiding the decline in insulation performance and structural damage caused by seal failure, thus ensuring the overall functionality and service life of the polar building. See further Figure 7-9 Another embodiment of the present invention discloses a construction method for the joint of the enclosure of a base building, comprising: prefabricating a modular main structure 10 and an enclosure structure 20, wherein the main structure 10 and the enclosure structure 20 are connected; splicing adjacent main structures 10, forming an installation gap 11 between adjacent main structures 10; filling the installation gap 11 with an elastic insulation structure 30, and connecting the elastic insulation structure 30 and the enclosure structure 20; telescopically installing the inner side of a waterproof structure 40 on the outer side of the elastic insulation structure 30 and the inner side of the enclosure structure 20 through a fixing plate 50, and then sealing the outer side of the enclosure structure 20 and the outer side of the waterproof structure 40 with adhesive.

[0044] By combining the prefabricated modular main structure 10 and enclosure structure 20 with the elastic thermal insulation structure 30 and the expandable waterproof structure 40 in a specific construction sequence, construction and processing errors and temperature deformation can be effectively accommodated in the enclosure joints, thereby achieving the effect of maintaining waterproof and thermal insulation performance and reducing later maintenance in extreme environments.

[0045] Specifically, the prefabrication and modularization process ensures the precision of components processed domestically, avoiding deviations caused by low temperatures during on-site processing in polar regions. The elastic insulation structure 30 fills the installation gap 11 and connects to the enclosure structure 20, utilizing its elastic properties to absorb relative displacement between the main structure 10 and the enclosure structure 20 while providing insulation. The waterproof structure 40 is retractably sealed outside the elastic insulation structure 30 and the enclosure structure 20, adapting to gap changes through its retractable design to maintain airtightness and watertightness during deformation. Based on these technical solutions, the enclosure system can dynamically adapt to temperature fluctuations in different polar seasons, preventing damage to the glass cladding layer 22 due to compression, and significantly improving the long-term stability and maintainability of the building envelope system.

[0046] This invention ensures the airtightness, watertightness, and thermal insulation performance of the maintenance system by setting three equal pressure chambers in its structure, setting thermal insulation materials, and aligning the isotherm and waterproof line with the main surface, while accommodating expansion and contraction.

[0047] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
