[0002] The glass sash, also known as a glass window sash, is the core component of a thermally broken window that supports the glass. Its structural design directly affects the window's heat insulation, sound insulation, waterproofing, and overall performance. Existing glass sashes typically consist of inner and outer sashes, as well as thermal insulation components connecting them. For example, Chinese utility patent CN215632483U, entitled "A Two-Tone Glass Window Sash Based on Seamless Welding Technology," includes a first glass sash, a second glass sash, and a screen. The first glass sash comprises an outer sash, an inner sash, and a connecting piece. At least one thermal insulation strip is installed between the outer sash and the connecting piece. The second glass sash comprises an outer sash and an inner sash. At least one thermal insulation strip is installed between the outer sash and the inner sash. The installation of thermal insulation strips one and two ensures the heat insulation performance of this two-tone glass window sash. (See attached...) Figure 3 As shown, the grooves of the inner and outer window sashes have an inner wider and outer narrower structure, and the ends of the thermal insulation strip are set wider to allow the thermal insulation strip to be inserted into the grooves of the inner and outer window sashes from the left and right.
[0003] However, the existing technology still has the following drawbacks:
[0004] 1. The existing glass window sash uses a left-right insertion structure with thermal insulation strips between the inner and outer sash frames. This is very inconvenient to install in limited space on both sides, affecting construction efficiency.
[0005] 2. The existing fan frame assembly and sub-frame assembly lack further heat insulation and sound insulation structural design measures on the overlapping side inside, resulting in unsatisfactory heat insulation and sound insulation effect of the fan frame assembly, as well as insufficient strength of the overlapping structure between the fan frame assembly and the sub-frame assembly, which cannot meet the user's higher quality requirements.
[0006] 3. The existing fan frame cavity, which is formed by connecting the internal and external fan frames through heat insulation strips, is usually uneven due to the limitations of the insertion structure between the fan frame groove and the heat insulation strip. This causes many inconveniences in the production and processing of the fan frame and also makes it difficult to fill the fan frame cavity with sound insulation material. Utility Model Content

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0038] like Figure 1-4 As shown, a conveniently installed sash structure is the core component of a thermally broken window that supports the glass, providing functions such as heat insulation, sound insulation, and waterproofing in practical use. This conveniently installed sash structure includes a main frame assembly 10, a sub-frame assembly 20, and a sash frame assembly 30. The main frame assembly 10 is fixedly connected to the building wall using expansion bolts; the sash frame assembly 30 is embedded and connected to the edge of the insulated glass 40 using corner brackets; and the sub-frame assembly 20 is installed between the main frame assembly 10 and the sash frame assembly 30 using a snap-fit structure including thermal insulation components.
[0039] The fan frame assembly 30 has an inner fan frame 301 and an outer fan frame 302, both of which are made of aluminum alloy. At the relative connection ends of the inner and outer fan frames 301 and 302, fan frame connecting grooves 303 of a certain depth (e.g., groove depth 7-12mm) are machined, and the inner walls of the grooves are provided with several trapezoidal grooves 3031. The inner fan frame 301 and the outer fan frame 302 are connected by an embedded first heat insulation member 80. This first heat insulation member 80 is made of PA66+GF25 material, and symmetrical heat insulation counterstrippers 801 (e.g., counterstripper height 2-3mm, inclination angle 15°-20°) matching the grooves 3031 are provided on both sides of the left and right ends of the first heat insulation member 80.
[0040] During installation, one end of the first heat insulation component 80 is pressed into the fan frame connecting groove 303 of the inner fan frame 301. The reverse teeth and groove 3031 are interlocked to form a mechanical lock. Then, the slot of the same structure of the outer fan frame 302 is aligned with the other end of the first heat insulation component 80 and pressed in, so as to achieve quick assembly in the front and back direction (not the traditional left and right plug-in), without the need for left and right adjustment space.
[0041] The inner fan frame 301 has an integrally formed sealed aluminum fan frame cavity 3011 with a rectangular cross-section on the inner side. The cavity wall thickness is 1.2mm. The inner fan frame 301 is connected to the top of the sub-frame assembly 20 through the lower part of the fan frame cavity 3011 via a heat insulation component.
[0042] Thus, in this embodiment of the application, the inner fan frame 301 and the outer fan frame 302 are fastened together by a fan frame connecting groove 303 and a first heat insulation member 80 with heat-insulating reverse teeth 801, enabling rapid assembly in the front-to-back direction. This allows for fan frame assembly to be completed in narrow spaces without lateral movement, which is more convenient than left-to-right insertion, free from space limitations, and improves installation efficiency by more than 40%. Furthermore, the reverse-locking structure of the heat-insulating reverse teeth 801 ensures a tensile strength of 300 N / mm² between the inner fan frame 301 and the outer fan frame 302. 2 Furthermore, by providing an inner cavity 3011 for the inner sash frame 301 facing the interior, it facilitates assembly with the sub-frame assembly 20, improves the structural strength of the connection between the frames, and reduces the overall window heat transfer coefficient to 1.2 W / (m²) through the sealing design of the inner cavity 3011. 2 ·K), reducing the thermal bridging effect, resulting in a 25% reduction in heat transfer coefficient compared to traditional structures.
[0043] The first heat insulation component 80 has heat insulation protrusions 802 with a certain height and width on both sides of the middle part (e.g., the height of the protrusion is 8mm and the width is 15mm). The material is the same as the main body. The two sides of the heat insulation protrusions 802 are tightly fitted to the connecting end faces of the inner fan frame 301 and the outer fan frame 302, respectively.
[0044] When necessary, the thermal insulation protrusion 802 is embedded with a polyurethane foam layer to reduce the thermal conductivity. The thermal insulation protrusion 802 creates a 3mm air gap between the profiles, increasing the thermal resistance by 35% and effectively blocking the heat conduction path. When the fan frame deforms due to temperature, the thermal insulation protrusion 802 can generate ±1.5mm of elastic deformation compensation. The elastic compensation structure ensures that the airtightness of the connection is maintained at ≥IP5X level.
[0045] Alternatively, the heat-insulating protrusion 802 has a honeycomb-like microporous structure inside, with a pore diameter of 0.5mm and a pore density of 20 pores / cm³. 2 The honeycomb structure reduces the thermal conductivity of the material to 0.28 W / (m·K), improving the thermal insulation performance by 18% compared to the solid structure.
[0046] The inner fan frame 301 and the outer fan frame 302 are connected and assembled through the first heat insulation member 80 to form a fan frame cavity 304 with a rectangular or circular cross-section, wherein the flatness error of the inner wall 3041 is ≤0.2mm. The end of the heat insulation protrusion 802 of the first heat insulation member 80 is processed into a flat-head structure, and the end of the heat insulation protrusion 802 extends to be flush with the inner wall 3041 of the central cavity of the fan frame cavity 304, ensuring the flatness of the inner wall 3041 of the central cavity of the assembled fan frame cavity 304, improving the filling effect of the sound insulation material, and the flush design of the heat insulation protrusion 802 and the inner wall 3041 of the central cavity avoids the formation of sound bridges, reducing the mid-to-high frequency sound insulation loss by 15dB.
[0047] In this embodiment, centrifugal glass wool and other sound insulation cotton 50 (density 32kg / m³) are used. 3 The filling rate of the fan frame cavity 304 and inner cavity 3011 is ≥95%. Therefore, the smooth inner wall 3041 of the fan frame cavity 304 increases the density of the sound insulation cotton 50 by 30%, achieving an airborne sound insulation of 42dB; moreover, the combined double-cavity structure reduces the overall heat transfer coefficient to 0.9W / (m²). 2 •K); An outer cavity 3021 is also provided on the outer fan frame 302 to further improve the heat insulation and sound insulation effect.
[0048] The inner fan frame 301 of the fan frame assembly 30 has a fan frame positioning cavity 3012 installed on its top. This fan frame positioning cavity 3012 is spaced a certain distance from the top protrusion of the outer fan frame 302, thus forming a glass mounting groove 305 on the top of the assembled inner fan frame 301 and outer fan frame 302. The glass mounting groove 305 is approximately 15mm deep, and a buffer pad 60 made of EPDM material (Shore 70±5 hardness) is placed at the bottom of the groove. The pad has a U-shaped cross-section and a 2mm thick shock-absorbing rubber layer at the bottom, forming a surface contact with the 12mm tempered glass edge of the insulated glass 40. In addition, equidistant buffer teeth 601 with a height of 1.5mm, a tooth pitch of 4mm, a tooth tip angle of 60°, and a stress relief groove of a certain width is formed at the root of the teeth.
[0049] Therefore, by setting a buffer pad 60 in the glass mounting groove 305 at the top of the sash frame assembly 30 to support the installation of the insulating glass 40, the buffer pad 60 absorbs more than 90% of the installation impact force, reducing the glass breakage rate from the traditional 5% to 0.3%. The U-shaped structure ensures uniform stress on the glass edge, improving wind pressure resistance to 2500Pa, thus achieving vibration damping installation of the insulating glass 40. Furthermore, equidistant buffer teeth 601 are set on the contact surface between the buffer pad 60 and the insulating glass 40. Through optimized design of the tooth pitch, tooth tip angle, and stress relief groove of the buffer teeth 601, the service life of the pad is effectively extended, cracking is avoided, and vibration damping installation of the insulating glass 40 and the sash frame assembly 30 is further improved.
[0050] When installing the insulated glass 40 on the glass mounting groove 305, EPDM rubber seals 110 are respectively installed on the inner side of the sash frame positioning cavity 3012, and silicone foam sealing strips are installed on the top protrusion of the outer sash frame 302. Then, the seals 110 on the sash frame positioning cavity 3012 and the top protrusion are tightly installed on both sides of the insulated glass 40, so that the seals 110 and the contact surface of the insulated glass 40 are subjected to a pre-tightening force of 2N / mm, which improves the installation and sealing effect of the insulated glass 40 and the sash frame assembly 30, and ensures the heat insulation and sound insulation effect.
[0051] The sub-frame assembly 20 of this embodiment adopts a thermal break design and can be made of 6063-T5 aluminum alloy. The sub-frame assembly 20 has an inner sub-frame 201 and an outer sub-frame 202. A sub-frame connecting groove 203 is provided at the connection end between the inner sub-frame 201 and the outer sub-frame 202. The inner sub-frame 201 and the outer sub-frame 202 are assembled approximately by a second thermal insulation component 90 (20mm wide) with a dovetail groove. The inner sub-frame 201 has a rectangular inner cavity 2011 filled with polyurethane foam; the outer sub-frame 202 has a rectangular outer cavity 2021 filled with rock wool.
[0052] Therefore, by using the dovetail groove structure of the second heat insulation component 90 to assemble and connect the inner sub-frame 201 and the outer sub-frame 202 from left to right, the size of the assembly can be reduced. The dual-cavity structure of the inner cavity 2011 and the outer cavity 2021 of the sub-frame, along with the heat insulation filling, reduces the heat transfer coefficient of the sub-frame to 1.0 W / (m²). 2 ·K).
[0053] A screen fan 70 is installed on the inner sub-frame 201. A slot and a sealing element 110 are provided on the inner sub-frame 201 to seal the screen fan 70, further improving the heat and sound insulation effect. Alternatively, the screen fan 70 can be fixed with stainless steel spring clips. The clips are spaced 200mm apart, with a clamping force of 15N / clip. The spring clips increase the efficiency of screen fan assembly and disassembly by 5 times and provide a deformation resistance of 500N / m.
[0054] The main frame assembly 10 in this embodiment adopts a thermal break design and can be made of 6063-T5 aluminum alloy. The main frame assembly 10 has an inner main frame 101 and an outer main frame 102. The inner main frame 101 and the outer main frame 102 are connected by a second thermal insulation component 90 (20mm wide) with a dovetail groove, approximately assembled together. The inner main frame 101 has a rectangular inner cavity 1011 filled with polyvacuum insulation board or urethane foam; the outer main frame 1022 has a rectangular outer cavity 1021 filled with aerogel felt or rock wool, reducing the heat transfer coefficient of the main frame to as low as 0.8 W / (m²). 2 ·K).
[0055] Therefore, the main frame assembly 10, as the main load-bearing structure, is equipped with stainless steel reinforcing ribs (1.5mm thick) at the connection between the inner main frame 101 and the outer main frame 102, increasing the bending stiffness to 4500 N·mm. 2 / mm, thereby strengthening the reinforcing bars to enable the main frame to bear a load of 300kg / m, suitable for super high-rise buildings.
[0056] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
