Description

Technical Field

[0001] The utility model relates to the field of doors and windows, and particularly relates to a door and window profile assembly and a door and window. Background Art

[0002] As an opening component in the enclosure structure, doors and windows are weak links in sound insulation and heat transfer. The sound insulation of traditional ordinary broken bridge aluminum alloy doors and windows is small, and it is difficult to meet the high sound insulation requirements of noise-sensitive buildings such as educational and medical buildings.

[0003] The profile of ordinary broken bridge aluminum alloy has a low melting point. The system is difficult to meet the fire resistance requirement of fire resistance integrity for 1 h. Steel liners must be added in the cavity. However, the steel liners are prone to rusting after being penetrated by screws or having drainage holes opened. Moreover, after the fireproof expansion strips are stuffed into the cavity of the broken bridge aluminum alloy, heat preservation treatment cannot be carried out, and heat bridges are easily formed, so the heat preservation performance is also poor. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the sound insulation, fire resistance, and heat preservation performance of traditional ordinary broken bridge aluminum alloy doors and windows, and to provide a door and window profile assembly and a door and window.

[0039] Embodiment 1

[0040] Such as Figures 1 - 3As shown, a door and window profile assembly includes a window frame profile 1 and a window sash profile 2 that are connected in cooperation. Both the window frame profile 1 and the window sash profile 2 are glass fiber reinforced polyurethane structural members. The profiles made of glass fiber reinforced polyurethane material itself has a relatively low thermal conductivity, about 0.33 - 0.36 W / m·K. The profiles made of glass fiber reinforced polyurethane material have good fire resistance. There is no need for steel liners or fireproof grouting, and fire expansion strips can be equipped to achieve better fire resistance. The profiles made of glass fiber reinforced polyurethane material can be integrally produced and designed. Under the condition permitted by the specification, strictly control the length-width ratio of the frame to achieve better mechanical properties. That is, the glass fiber reinforced polyurethane composite material has a lower k value compared with traditional window profiles (aluminum alloy broken bridge windows); it has better fire integrity compared with plastic steel windows, and its mechanical properties are much higher than those of traditional window profiles (aluminum alloy broken bridge windows, plastic steel windows, wooden keel windows, etc.), which is safe and reliable.

[0041] As Figure 2 shown, the window frame profile 1 is formed with a plurality of window frame cavities 13, preferably at least 3 window frame cavities 13, and more preferably 3 - 6 window frame cavities 13. The window frame cavities 13 are filled with a heat insulation material 3, and the heat insulation material 3 can be a foamed polyurethane material or rock wool, etc. Due to the filling of the heat insulation material 3, it can thus have good heat insulation performance.

[0042] As Figure 3 shown, the window sash profile 2 is formed with a plurality of window sash cavities 23, preferably at least 3 window sash cavities 23, and more preferably 3 - 6 window sash cavities 23. Each window sash cavity 23 is filled with a heat insulation material 3, and the heat insulation material 3 can be a foamed polyurethane material or rock wool, etc. Due to the filling of the heat insulation material 3, it can thus have good heat insulation performance.

[0043] A rubber strip installation groove 11 is provided in the middle of the window frame profile 1. An intermediate rubber strip 4 is fixedly installed in the rubber strip installation groove 11, such as by snap connection. The other end of the intermediate rubber strip 4 can abut against the window sash profile 2. Further, the width of the intermediate rubber strip 4 can be greater than 1 / 3 of the width of the window frame profile 1, so as to form more and wider contact surfaces with the window frame profile 1 and the sash frame profile 2, enhancing the sealing performance of the profiles to achieve better sound insulation performance.

[0044] Further, a plurality of outward convex points 43 are provided on the intermediate rubber strip 4, and the outward convex points 43 are used to contact the window sash profile 2. The outward convex points 43 may have an arc-shaped outer surface or a smooth irregular curved surface, etc. For example, the outward convex points 3 may be hemispherical, semi-elliptical, or other smooth irregular bodies. The number of the outward convex points 43 is at least 2, and further preferably 2-6. By providing the outward convex points 43, on the basis that the main body of the intermediate rubber strip 4 abuts against the window sash profile 2, the outward convex points 43 further contact and tightly abut against the window sash profile 2 to form an effect of multiple contacts, thereby improving the sealing performance.

[0045] As Figure 4 shown, in an optional embodiment, the intermediate rubber strip 4 may include a first rubber strip portion 41 and a second rubber strip portion 42 integrally formed, the elasticity of the second rubber strip portion 42 is greater than that of the first rubber strip portion 41, and the outward convex points 43 are provided on the outer surface of the second rubber strip portion 42. The outward convex points 43 and the second rubber strip portion 42 may be an integrally formed structural member. For example, the intermediate rubber strip 4 is an ethylene propylene diene monomer (EPDM) structural member, the first rubber strip portion 41 is an EPDM solid structural member, and the second rubber strip portion 42 and the outward convex points 43 are both EPDM foamed structural members. By providing two rubber strip portions with different elasticities, on the basis of ensuring the sealing performance through the harder first rubber strip portion 41, by providing the softer second rubber strip portion 42, it is more convenient to open and close, and the comfort of use is improved.

[0046] Further, at least three rubber strip cavities 44 are formed in the intermediate rubber strip 4, and further preferably 3-6. By providing the rubber strip cavities 44, on the basis of improving the sealing performance and sound insulation performance of the profile, the convenience and comfort of opening and closing the doors and windows are also improved.

[0047] The installation and cooperation method of the window frame profile 1 and the window sash profile 2 may be:

[0048] A first clamping groove 12 is formed at the upper end of the window frame profile 1, the upper end of the window sash profile 2 is clamped with the first clamping groove 12 through a first clamping member 5, and the first clamping member 5 may include a sealing rubber strip.

[0049] A second clamping groove 22 is formed at the lower end of the window sash profile 2, the lower end of the window frame profile 1 is clamped with the second clamping groove 22 through a second clamping member 6, and the second clamping member 6 may include a sealing rubber strip.

[0050] For the sound insulation and fire-resistant door and window profile assembly of the present utility model, through the selection of glass fiber reinforced polyurethane composite material, the design of the profile and the design of the intermediate rubber strip, under the same glass configuration, the k value is reduced by about 0.4W / m compared with the aluminum alloy door and window 2k can also achieve a fire resistance performance with a fire integrity of 1 h in terms of fire resistance. Through the optimization of profiles and intermediate rubber strips, the sound insulation performance can reach up to 40 dB. On the premise of maintaining high performance, the problem of a significant increase in cost caused by high-performance requirements is also solved.

Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
