Description

Technical Field

[0001] This utility model relates to the field of warehouse building doors and windows technology, and in particular to a window sash with a thermal break structure and a grain warehouse sealing window using the same. Background Technology

[0002] Maintaining a constant temperature within grain storage facilities is a crucial technical measure to prevent insect infestation, condensation, aging, and mold growth in grain, thereby ensuring its storage quality. In this context, the thermal insulation performance of grain storage structures, especially the insulation effect of sealed windows, directly impacts energy consumption and grain storage safety.

[0003] Currently, the most commonly used sealing windows in grain silos are embedded sealing windows. These windows have the following significant drawbacks: Firstly, in terms of structural installation, the window frame is directly embedded into the grain silo window opening. This structure requires the sealed windows to be customized according to the specific dimensions of each window opening, resulting in poor versatility. This not only increases production costs but also causes great inconvenience and low efficiency for on-site installation.

[0004] Secondly, regarding thermal insulation performance, the existing sealed windows in grain silos are primarily made of metal for both the sashes and frames, and no effective thermal break is installed between their internal and external structures. Due to the inherent high thermal conductivity of metal, in hot summer weather, the external structure of the sashes and frames, rapidly heated by sunlight, forms a continuous heat conduction path with the internal structure, creating a significant "thermal bridge" effect. This allows external heat to be quickly and unimpededly conducted into the grain silo through the metal components, severely disrupting the constant temperature environment required for grain storage and greatly increasing the risk of grain damage. Especially in southern regions, refrigeration equipment frequently operates at high loads to maintain a constant temperature, resulting in enormous energy waste.

[0005] Therefore, there is an urgent need in this field for a new type of sealed grain warehouse window that can overcome the above-mentioned defects. It should be easy to install, highly versatile, and have excellent thermal insulation performance. Utility Model Content

[0006] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a window sash with a thermal break structure and a grain warehouse sealing window using the same structure, so as to achieve the goals of easy installation, strong versatility, and excellent thermal insulation performance.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A window sash with a thermal break structure, comprising: The front panel, side panels, and back panel together form a cavity; An insulation layer is filled into the cavity; The connector, which is made of thermal insulation material, is disposed in the peripheral side plate and / or at the junction of the peripheral side plate and the back plate, forming a thermal break structure between the front panel and the back plate.

[0008] As a limitation of this utility model, the window sash is intended for installation on a building.

[0009] As another limitation of this utility model, the connector includes a profile connected between the periphery of the back plate and the peripheral side portion.

[0010] As a further limitation of this utility model, a sealing groove is machined along the length direction on the outer side of the profile; a sealing strip is embedded in the sealing groove, and the sealing strip protrudes from the back plate.

[0011] As a further definition of this utility model, the sealing strip includes an installation portion embedded in the sealing groove and a first sealing portion protruding from the plane of the back plate.

[0012] As a further limitation of this utility model, the sealing strip also includes a second sealing portion extending to the outer side surface of the peripheral side plate.

[0013] As another limitation of this utility model, the insulation layer includes a support frame placed in the cavity and a filling layer filled around the support frame.

[0014] This utility model also discloses a grain warehouse sealing window, including a window frame and a window sash rotatably mounted on the window frame; the window frame and the grain warehouse window opening have a predetermined dimensional relationship, so that the window frame can be externally installed in a way that covers the window opening; the window sash is a window sash with a thermal break structure as described above.

[0015] As a limitation of this utility model, it also includes a frame-shaped base plate and a partition plate. The base plate, the partition plate and the window frame are all provided with mounting holes and are configured to achieve alignment and fixed connection of the three by fasteners passing through these mounting holes. The base plate is used to contact the outer wall of the grain silo; the partition is a heat insulation material and is sandwiched between the window frame and the base plate to form a thermal break structure between the window frame and the base plate; When the window sash is closed, the first sealing part of the sealing strip contacts the partition to seal and thus create a thermal break between the inside of the grain warehouse and the outside.

[0016] As a further limitation of this utility model, the gap formed between the outer frame of the window frame, the outer perimeter of the base plate, and the outer wall of the grain warehouse is filled with a foaming adhesive layer, and a structural adhesive layer is sealed on the outside to form a broken bridge structure between the base plate and the open environment.

[0017] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: (1) Excellent thermal insulation performance of the window sash itself: The window sash disclosed in this utility model innovatively adopts a thermal break structure with low thermal conductivity connectors as the core. That is, by utilizing the extremely low thermal conductivity of thermal insulation materials (such as plastics), connectors made of thermal insulation materials are set at the connection between the back panel and the side panel and / or in the side panel, effectively blocking the heat conduction path caused by direct contact between the panel → side panel → back panel. Combined with the foam filling layer in the cavity, the efficiency of external heat transfer to the interior of the warehouse through the window sash is significantly reduced, achieving excellent thermal insulation performance.

[0018] (2) Multi-layered thermal break structure for comprehensive thermal bridging: The grain storage sealing window disclosed in this utility model constructs a multi-layered and systematic thermal break system. That is: Window sash body thermal break: The window sash itself adopts an innovative thermal break design, connecting the back panel and the perimeter panel through low thermal conductivity connectors (and / or connecting the outside and inside of the perimeter panel through low thermal conductivity connectors), and is filled with high-efficiency thermal insulation material, forming a core thermal break layer that blocks heat transfer. Window frame-base plate partition: The thermal insulation material partition is sandwiched between the window frame and the base plate, forming the first auxiliary thermal break to prevent heat transfer from the window frame to the building structure; Window sash-frame sealing thermal break: When the window sash is closed, its sealing strip is tightly pressed against the partition, effectively sealing the gap between the window sash and the window frame, realizing a reliable isolation between the inside of the grain warehouse and the external environment, forming a second auxiliary thermal break to prevent external heat from being transferred to the inside of the grain warehouse through the gap. Window frame-wall sealing thermal break: The gap between the outer edge of the window frame and the outer perimeter of the base plate and the outer wall of the grain silo is filled with a layer of expanding foam, and a structural adhesive layer is injected on the outside. While ensuring sealing and waterproofing, it also forms a third auxiliary thermal break to prevent heat from being transferred from the installation gap to the inside of the grain silo and from the base plate to the inside of the grain silo.

[0019] This multi-layered design, working synergistically from the inside out and from the core to the periphery, effectively cuts off the main heat transfer channels from the external environment to the interior of the grain warehouse.

[0020] (3) Easy installation and strong versatility: This utility model adopts an external modular design, which does not require precise embedding into the window opening. Only a few standard sizes need to be produced to adapt to window openings of various sizes, which is very versatile. Through the base plate structure, the lightweight base plate can be positioned, leveled and fixed separately at the window opening. Then, the heavy window frame body is installed with the base plate as a reference, which greatly simplifies the installation process, saves time and effort, and reduces the workload and installation cost.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0024] refer to Figures 1 to 8 This utility model provides a window sash 1 with a thermal break structure and a grain warehouse sealing window including the window sash 1.

[0025] Example 1: A window sash with a thermal break structure 1 This window sash 1 is intended for installation on buildings, and is particularly suitable for grain warehouse window openings 10. (Reference) Figure 1 The window sash 1 includes a panel 101, a side panel 106, a back panel 102, an insulation layer 103, a connector 104, and a sealing strip 105.

[0026] In this embodiment, the panel 101, the peripheral side panel 106, and the back panel 102 are all made of metal (such as aluminum alloy or steel plate), and the three together form a closed cavity. As a preferred embodiment, the peripheral side panel is an integral structure formed by bending and extending the periphery of the panel 101 through stamping or other methods, thus forming a box-shaped structure with accommodating space together with the panel 101. Figure 5 or Figure 7 As shown, the back panel 102 is disposed opposite to the front panel 101, and its edge portion is engaged with the end of the peripheral side panel 106 through the aforementioned connector 104, thereby forming a closed cavity together with the front panel 101 and the peripheral side panel 106.

[0027] The insulation layer 103 fills the aforementioned cavity, and its function is to significantly reduce heat conduction through the window sash 1. Specifically, the insulation layer 103 includes a support frame 107 placed within the cavity and a filling layer 108 surrounding the support frame 107. The support frame 107 can be composed of a metal or plastic frame and a "star" or "grid" shaped support structure connected inside the frame, mainly used to maintain the basic shape of the cavity and provide structural strength. The filling layer 108 is a foamed insulation material. In this embodiment, the filling layer 108 is rigid polyurethane foam, which, after foaming and curing, forms an insulation core layer with extremely low thermal conductivity and certain structural strength, i.e., the filling layer 108. Flame retardants can be mixed into the filling layer 108 to give it flame-retardant properties, depending on the actual situation.

[0028] The connector 104 is made of a low thermal conductivity insulating material (such as PVC, nylon, polytetrafluoroethylene, hard rubber, carbon fiber, etc.). It is a profile that connects the periphery of the back plate 102 to the end of the peripheral side plate 106 via mechanical connection or snap-fit, achieving a contactless connection between the back plate 102 and the peripheral side plate 106. Because the thermal conductivity of the connector 104 (i.e., the profile) is much lower than that of metal, it effectively blocks the direct heat conduction path between the metal panel 101, the metal peripheral side plate 106, and the metal back plate 102, forming a highly efficient "broken bridge" structure. In this embodiment, the profile is connected between the periphery of the back plate 102 and the end of the peripheral side plate 106 via snap-fit. The cross-sectional shape of the profile is referenced. Figure 5 It has a right-angle portion on one side for abutting against the end of the peripheral side plate 106, and a slot portion on the other side for inserting into the periphery of the back plate 102.

[0029] Furthermore, a sealing groove is machined along the length of the outer side of the profile (i.e., the side facing the inner side of the window sash 1). The sealing strip 105 is tightly fitted into this sealing groove, and the sealing strip 105 protrudes from the plane of the back panel 102, as shown in the reference section. Figure 5 or Figure 7 This ensures that when the window sash 1 is closed, it forms a tight, sealed contact with the corresponding part (i.e., partition 4) on the window frame 2. In this embodiment, the sealing strip 105 is made of EPDM rubber (or silicone depending on the situation), and includes an installation part 109 for embedding in the sealing groove and a first sealing part 110 protruding from the plane of the back plate 102.

[0030] As another optional implementation, the structure of the sealing strip 105 can be found in [reference needed]. Figure 9 In this structure, in addition to the mounting portion 109 embedded in the sealing groove and the first sealing portion 110 for sealing the gap between the window sash 1 and the partition 4, the sealing strip 105 also has a second sealing portion 111. The second sealing portion 111 extends from the mounting portion 109 and covers part of the outer side surface of the peripheral side plate 106, and is used to seal the gap between the window sash 1 and the window frame 2, thereby working with the first sealing portion 110 to achieve multiple seals on the window sash 1.

[0031] Example 2: A window sash with a thermal break structure 1 This embodiment discloses another window sash 1 with a thermal break structure, whose basic structure is the same as that of Embodiment 1, including a panel 101, a peripheral side panel 106, a back panel 102, an insulation layer 103, and a thermal break structure formed by a connector 104 and a sealing strip 105. The difference lies in the configuration of the peripheral side panel 106 and the way the thermal break structure is set.

[0032] Specifically, in this embodiment, the peripheral side panel 106 is a split structure, including a first frame and a second frame. The first frame is integrally formed by bending and extending the periphery of the panel 101 through stamping or other methods; the outer end of the second frame (i.e., the end closer to the panel 101) is connected to the end of the first frame through a first connector, which is a non-contact connection; the inner end of the second frame (i.e., the end closer to the back panel 102) is connected to the edge of the back panel 102 through a second connector, which is a non-contact connection.

[0033] Both the first and second connectors are made of thermally insulating materials with low thermal conductivity (such as PVC, nylon, polytetrafluoroethylene, hard rubber, carbon fiber, etc.). The specific structure of the first and second connectors can be the same as that of connector 104 in Embodiment 1, and the first frame and the second frame, the second frame and the back plate 102 are fixed by snap-fit. Furthermore, sealing strips 105 are tightly embedded in both the first and second connectors.

[0034] In this configuration, the first connector effectively blocks the heat conduction path from the panel 101 and the first frame to the second frame, while the second connector 1 effectively blocks the heat conduction path from the second frame to the back panel 102. Thus, through the combined action of the two connectors 104, a more thorough multi-segment thermal break structure is formed on the window sash 1, further improving the overall thermal insulation performance.

[0035] Example 3: A window sash with a thermal break structure 1 This embodiment discloses another window sash 1 with a thermal break structure, whose basic structure is the same as that of embodiment 2. The peripheral side panel 106 also adopts a split structure composed of a first frame and a second frame.

[0036] The difference between this embodiment and Embodiment 2 lies in the simplified arrangement of the thermal break structure. Specifically, in this embodiment, the first connecting member is only provided inside the peripheral side plate 106 (i.e., between the first frame and the second frame) to form the core thermal break structure. Simultaneously, the second connecting member provided between the second frame and the back plate 102 in Embodiment 2 is eliminated, allowing the inner end of the second frame to be directly connected to the edge of the back plate 102. In this embodiment, the second frame can be integrally formed by bending and extending the periphery of the back plate 102 through methods such as stamping.

[0037] This design, through a single first connector, can still effectively block the main heat transfer from the panel 101 and the first frame to the second frame and the back panel 102.

[0038] Example 4: A grain warehouse sealing window refer to Figures 1 to 3 The sealed window of the grain warehouse includes a window frame 2, a window sash 1, a base plate 3, and a partition 4.

[0039] Window frame 2 is typically made of metal profiles. For convenient external mounting, refer to... Figure 8 The outline dimensions of window frame 2 are configured to be greater than or equal to the dimensions of grain silo window opening 10. This allows window frame 2 to completely cover the exterior wall of grain silo window opening 10 and be directly fixed with fasteners such as expansion bolts, avoiding the drawbacks of traditional recessed installations that require precise dimensional customization of window frame 2, and achieving modular production and universal installation.

[0040] Window sash 1 is the window sash with a thermal break structure described in Embodiment 1, which is rotatably mounted on window frame 2. In this embodiment, window sash 1 is rotatably mounted to window frame 2 through a rotating connection mechanism. Specifically, the rotating connection mechanism includes a rotating shaft 6, at least a pair of bearings 7, and at least one connecting angle iron 8. The rotating shaft 6 is rotatably supported on window frame 2 via bearings 7, and the connecting angle iron 8 is fixedly connected to both the rotating shaft 6 and the frame of window sash 1, thereby converting the opening and closing action of window sash 1 into the rotational motion of rotating shaft 6. This rotating connection mechanism is prior art and ensures the smooth and stable opening and closing operation of window sash 1.

[0041] Both base plate 3 and partition plate 4 are frame structures, see reference. Figure 2 The base plate 3 (usually a metal plate) is used for direct contact with the outer wall of the grain silo. The partition 4 is made of a low thermal conductivity insulating material (such as PVC, nylon, polytetrafluoroethylene, hard rubber, carbon fiber, etc.) and is a frame-type component. In this embodiment, its shape and size are exactly the same as the base plate 3. It is understood that in other alternatives, the shape or size of the two may also be different, the core being to ensure that when the window sash 1 is closed, the first sealing part 110 of the sealing strip 105 can reliably contact the surface of the partition 4 and form an effective seal.

[0042] The base plate 3, partition plate 4, and window frame 2 are all pre-drilled with precisely corresponding and compatible mounting holes, and the three are aligned and securely fixed by fasteners (such as expansion bolts) passing through these mounting holes. In this structure, the partition plate 4 is sandwiched between the metal window frame 2 and the metal base plate 3. Utilizing its low thermal conductivity, it forms a thermal break structure between the window frame 2 and the base plate 3, preventing heat from the window frame 2 from being transferred to the base plate 3 and the wall.

[0043] Furthermore, the inner frame dimensions of the base plate 3 and partition plate 4 are smaller than the inner frame dimensions of the window frame 2, and the outer frame dimensions are smaller than the outer frame dimensions of the window frame 2. That is, after the base plate 3, partition plate 4, and window frame 2 are connected, a portion of the structure of the base plate 3 and partition plate 4 extends into the inner frame of the window frame 2, as shown in the reference section. Figure 5 and Figure 7 This forms a base for supporting the sealing strip 105 of the window sash 1.

[0044] When the window sash 1 is closed, the sealing strip 105 of the window sash 1 is tightly pressed against the part of the partition 4 that extends into the inner frame of the window frame 2, thereby effectively sealing the gap 5 between the window sash 1 and the window frame 2, reliably isolating the inside of the granary from the outside environment, and ensuring the overall airtightness and heat insulation effect.

[0045] As another alternative implementation method, such as Figure 9As shown, a groove 11 adapted to the first sealing part 110 of the sealing strip 105 can be provided on the partition 4 and the base plate 3. When the window sash 1 is closed, the first sealing part 110 can be tightly pressed into the groove 11. The mating structure of this groove 11 and the first sealing part 110 constitutes an effective anti-detachment mechanism, which can significantly improve the sealing stability and prevent the sealing strip 105 from shifting or detaching due to long-term use or vibration.

[0046] After the window frame 2 is fixed at the grain warehouse window opening 10, the gap formed between the outer edge of the window frame 2 and the outer perimeter of the base plate 3 and the outer wall of the grain warehouse (i.e. Figure 5 and Figure 7 Area A (9) as indicated in the label is filled with a foam layer and sealed with a weather-resistant structural adhesive layer (such as silicone structural adhesive) on the outside. This structure provides excellent rainproof and waterproof sealing. On the other hand, as it is also a poor conductor of heat, it forms a thermal break between the base plate 3 and the open environment outside the grain silo, blocking the path of heat transfer from the installation gaps to the inside of the grain silo and from the base plate 3 to the inside of the grain silo.

[0047] As a preferred embodiment, the inner periphery of the base plate 3 and partition plate 4 is also filled with a foamed adhesive layer between itself and the outer wall of the grain silo, and a weather-resistant structural adhesive layer is then sealed on the outside. This preferred embodiment achieves a more comprehensive airtight seal. Its key function is to effectively resist the static pressure load generated by the pressure difference between the inside and outside of the grain silo (especially the positive pressure formed inside the silo), preventing gas from forcibly penetrating or damaging the outer structural adhesive layer due to excessive internal pressure, thereby ensuring the long-term integrity and reliability of the sealing system.

[0048] It should be further explained that, to achieve the locking and opening of the window sash 1 relative to the window frame 2, the grain warehouse sealed window typically also includes a window sash locking structure and a window sash opening and closing actuator structure. The window sash locking structure is used to lock the window sash to the window frame 2 after it is closed, and the window sash opening and closing actuator mechanism is used to control the opening or closing of the window sash 1, i.e., to enable the window sash 1 to rotate relative to the window frame 2. Both the window sash locking structure and the window sash opening and closing actuator mechanism are mature technologies in the prior art and are not shown in the accompanying drawings; their structures will not be described in detail in this embodiment.

[0049] The installation process of the grain warehouse sealing window provided by this utility model is greatly simplified compared to traditional sealing windows: First, the lightweight base plate 3 is placed at the grain silo window opening 10. After adjusting its level and verticality, it is individually fixed to the wall using expansion bolts. Then, the partition plate 4 is installed, aligned with the base plate 3. Finally, the heavy window frame 2, with the window sash 1 already assembled, is hoisted to the predetermined position, aligning its mounting holes with the mounting holes on the partition plate 4 and the base plate 3, and then secured with expansion bolts. This process eliminates the need for repeated adjustments to the heavy window frame 2 at height, significantly reducing the difficulty and intensity of the installation work.

[0050] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
