Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a door and window mullion profile component and door and window structure. Background Technology

[0002] While aluminum alloy thermal break windows have advantages such as sturdy structure and beautiful appearance, their high heat transfer coefficient makes their thermal insulation performance relatively weak. Especially in cold or hot seasons, they can easily cause fluctuations in indoor temperature, increase the energy consumption of air conditioning or heating systems, and thus affect the comfort of the living environment and energy efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing aluminum alloy thermal break windows, which have a high heat transfer coefficient and therefore relatively weak thermal insulation performance, and to provide a mullion profile component and window structure.

[0004] In a first aspect, this utility model provides a door and window mullion profile assembly, comprising:

[0005] The first profile and the second profile cooperate with each other, and both the first profile and the second profile are glass fiber reinforced polyurethane structural components;

[0006] The first profile and the second profile each form a plurality of profile cavities, and each profile cavity is filled with thermal insulation material;

[0007] The first profile and the second profile are sealed together by a first sealing strip, a second sealing strip, and a third sealing strip. The sealing heads of the first sealing strip and the third sealing strip are both T-shaped. The second sealing strip is disposed in the cavity between the first profile and the second profile, and the second sealing strip divides the cavity between the profiles into two parts. The second sealing strip has a plurality of sealing strip cavities, wherein the sealing strip cavity furthest from the sealing strip mounting cavity is provided with an outward protrusion, which is used to achieve sealing.

[0008] This invention sets both the first and second profiles as glass fiber reinforced polyurethane structural components, and fills the cavity of the profiles with thermal insulation material. The glass fiber reinforced polyurethane structural components have a low thermal conductivity, which can effectively reduce the heat transfer coefficient of the entire window. The combination of glass fiber reinforced polyurethane structural components and thermal insulation material can improve the thermal insulation performance of doors and windows, and improve the comfort of the living environment and energy utilization efficiency.

[0009] Furthermore, this utility model sets the sealing heads of the first and third sealing strips to be T-shaped. The T-shaped sealing head can rebound and fill gaps in doors and windows, and can achieve compression sealing when there are no gaps in doors and windows. This achieves a better sealing effect than conventional sealing heads, improves the water tightness and air tightness of doors and windows, and also helps to improve the thermal insulation performance of doors and windows.

[0010] Furthermore, this utility model places a second sealing strip in the cavity between the first profile and the second profile, and divides the cavity between the profiles into two mutually isolated air chambers by the second sealing strip, which can further improve the heat insulation performance of the doors and windows.

[0011] Furthermore, the second sealing strip of this utility model is also provided with several sealing strip cavities, and an outward protrusion is provided at a distance away from the sealing strip cavities. Through the setting of the sealing strip cavities and the outward protrusion, the sealing connection between the first profile and the second profile can be further realized, thereby improving the sealing performance of the doors and windows, and also helping to improve the thermal insulation performance of the doors and windows.

[0012] Preferably, the second sealing strip has 2-3 sealing strip cavities.

[0013] Preferably, the width of the second sealing strip is less than 1 / 3 of the width of the first profile / second profile. This setting provides better clamping force for the second sealing strip, resulting in better sealing and heat preservation effects.

[0014] Preferably, the protruding part is a strip-shaped structural part.

[0015] Preferably, the elasticity of the outer protrusion is greater than that of the second sealing strip on the side closest to the sealing strip mounting cavity. By providing two strip portions with different elasticities, the sealing performance can be guaranteed by the harder strip portion, while the softer outer protrusion makes opening and closing easier and improves user comfort.

[0016] Preferably, the protruding part is a EPDM foamed structural part, and the side of the second sealing strip near the sealing strip mounting cavity is a solid EPDM structural part.

[0017] Preferably, the two sides of the first profile form a first slot group and a second slot group, and the two sides of the second profile form a third slot group and a fourth slot group, thereby facilitating the installation of glass, hardware, etc.

[0018] Preferably, the first sealing strip and the third sealing strip are one or two of the following: EPDM rubber strip, silicone rubber strip, thermoplastic vulcanized rubber strip, plasticized polyvinyl chloride strip, modified PVC strip, and vulcanized EPDM rubber strip.

[0019] Preferably, the thermal conductivity of the glass fiber reinforced polyurethane structural component is 0.33-0.36 W / m•k.

[0020] In a second aspect, the present invention provides a door and window structure, including any of the door and window mullion profile components described above.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. In this utility model, both the first profile and the second profile are set as glass fiber reinforced polyurethane structural components, and the cavity of the profile is filled with thermal insulation material. The glass fiber reinforced polyurethane structural component has a low thermal conductivity, which can effectively reduce the heat transfer coefficient of the entire window. The glass fiber reinforced polyurethane structural component and the thermal insulation material work together to improve the thermal insulation performance of the doors and windows, and improve the comfort of the living environment and energy utilization efficiency.

[0023] 2. In this utility model, the sealing heads of the first and third sealing strips are both T-shaped. The T-shaped sealing heads can rebound and fill gaps in doors and windows, and can achieve compression sealing when there are no gaps in doors and windows. This provides a better sealing effect than conventional sealing heads, improves the water tightness and air tightness of doors and windows, and also helps to improve the thermal insulation performance of doors and windows.

[0024] 3. This utility model places the second sealing strip in the cavity between the first profile and the second profile, and divides the cavity between the profiles into two mutually isolated air chambers by the second sealing strip, which can further improve the heat insulation performance of doors and windows.

[0025] 4. The second sealing strip of this utility model is further provided with several sealing strip cavities, and an outward protrusion is provided at a location away from the sealing strip cavities. Through the arrangement of the sealing strip cavities and the outward protrusion, the sealing connection between the first profile and the second profile can be further achieved, improving the sealing performance of the doors and windows, and also contributing to improving the thermal insulation performance of the doors and windows.

However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0033] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.

[0038] Example 1

[0039] like Figure 1 As shown, a mullion profile assembly for doors and windows includes a first profile 1 and a second profile 2 that cooperate with each other. Both the first profile 1 and the second profile 2 are glass fiber reinforced polyurethane (GFRP) structural components. GFRP profiles have a low thermal conductivity, approximately 0.33-0.36 W / m•K. They also possess excellent fire resistance, requiring no steel lining or fireproof grouting, and can be equipped with fire-resistant expansion strips for even better fire resistance. GFRP profiles can be manufactured and designed in an integrated manner, with strict control over the length-to-width ratio of the frame, within the limits of regulations, to achieve superior mechanical properties. Specifically, GFRP composite materials have a lower k-value compared to traditional window profiles (aluminum alloy thermal break windows); better fire resistance integrity compared to PVC windows; and significantly higher mechanical properties than traditional window profiles (aluminum alloy thermal break windows, PVC windows, wooden frame windows, etc.), making them safe and reliable.

[0040] like Figure 2-3 As shown, the first profile 1 and the second profile 2 each form a plurality of profile cavities 3, and each profile cavity 3 is filled with thermal insulation material. The specific number of profile cavities can be designed according to actual needs. More preferably, the first profile 1 and the second profile 2 can each form 1-4 profile cavities 3, and the thermal insulation material can be polyurethane foam or rock wool, etc. Due to the filling with the thermal insulation material, it can have good thermal insulation performance.

[0041] In an optional embodiment, the two sides of the first profile 1 respectively form a first slot group 10 and a second slot group 11, and the two sides of the second profile 2 respectively form a third slot group 12 and a fourth slot group 13. The first slot group 10, the second slot group 11, the third slot group 12 and the fourth slot group 13 can be used to install glass, hardware, etc. The size, position and quantity of the first slot group 10, the second slot group 11, the third slot group 12 and the fourth slot group 13 can be designed according to specific needs to make them more adaptable to more application scenarios.

[0042] The first profile 1 and the second profile 2 are sealed together by a first sealing strip 5, a second sealing strip 6, and a third sealing strip 7.

[0043] The first sealing strip 5 is installed at the end of the first profile 1 near the second profile 2, achieving a sealed connection between the first profile 1 and the second profile 2 at one end. The third sealing strip 7 is installed at the end of the second profile 2 near the first profile 1, achieving a sealed connection between the first profile 1 and the second profile 2 at one end. Both the first sealing strip 5 and the third sealing strip 7 have T-shaped sealing heads. The T-shaped sealing heads can spring back and fill gaps in the doors and windows, and can achieve compression sealing when there are no gaps. This provides a better sealing effect than conventional sealing heads, improving the water tightness and air tightness of the doors and windows, and also enhancing their thermal insulation performance. In optional embodiments, the first sealing strip 5 and the third sealing strip 7 are one or two of the following: EPDM rubber strips, silicone rubber strips, thermoplastic vulcanized rubber strips, plasticized polyvinyl chloride strips, modified PVC strips, and vulcanized EPDM rubber strips.

[0044] The first profile 1 and the second profile 2 form a cavity 4 between the profiles. The second sealing strip 6 is disposed within the cavity 4 formed by the first profile 1 and the second profile 2, and the second sealing strip 6 divides the cavity 4 between the profiles into two parts. Specifically, the second sealing strip 6 divides the cavity 4 between the profiles into two mutually isolated air chambers, which can further improve the thermal insulation performance of the doors and windows.

[0045] like Figure 4 As shown, the second sealing strip 6 has a plurality of sealing strip cavities 9. The number of sealing strip cavities 9 can be 2-3. The sealing strip cavities 9 can be arranged side by side (e.g., in a row) or in combination (e.g., in two or three rows). The arrangement of the sealing strip cavities 9 can further improve the heat insulation and thermal insulation performance of doors and windows.

[0046] Furthermore, the width w2 of the second sealing strip 6 is less than 1 / 3 of the width w1 of the first profile 1 / second profile 2. Through experiments and calculations, it can be seen that with this setting, the clamping force of the second sealing strip 6 is better, and it can achieve better sealing and heat preservation effects.

[0047] Furthermore, the second sealing strip 6 is also provided with an outward protrusion 8. The outward protrusion 8 can be a strip-shaped structural component, and its cross-section is typically hemispherical, semi-elliptical, or other smooth irregular shape. By providing the outward protrusion 8, better sealing and heat insulation can be achieved. Specifically, the outward protrusion 8 is located at the end of the second sealing strip 6 furthest from the sealing strip mounting cavity 14. That is, if the second sealing strip 6 is installed on the first profile 1, the outward protrusion 8 of the second sealing strip 6 is located at the end closest to the second profile 2; if the second sealing strip 6 is installed on the second profile 2, the outward protrusion 8 of the second sealing strip 6 is located at the end closest to the first profile 1.

[0048] Furthermore, to achieve better sealing and insulation effects, the elasticity of the protruding member 8 is set to be greater than that of the second sealing strip 6 on the side near the sealing strip mounting cavity 14. For example, the protruding member 8 is a EPDM foam structure, and the side of the second sealing strip 6 near the sealing strip mounting cavity 14 is a solid EPDM structure.

[0049] like Figure 1 As shown, the second sealing strip 6 may include an integrally formed first strip portion (without a filled area) and a second strip portion (with a filled area). The elasticity of the second strip portion is greater than that of the first strip portion. The protruding member 8 is disposed on the outer surface of the second strip portion. The protruding member 8 may be an integrally formed structural component with the second strip portion. For example, the second sealing strip 6 is a EPDM structural component, the first strip portion is a solid EPDM structural component, and both the second strip portion and the protruding member 8 are EPDM foam structural components. By providing two strip portions with different elasticities, the sealing performance can be guaranteed by the harder first strip portion, while the opening and closing are easier and the user comfort is improved by providing the softer second strip portion and the protruding member 8.
