Description

Technical Field

[0001] The present invention belongs to the technical field of energy-saving building doors and windows, and particularly relates to a composite material door and window profile and a micro-side pressure door and window system processed by using the door and window profile. Background Art

[0002] China has promised to the world to implement the "3060" goal. Building energy consumption accounts for about 30% of the total national energy consumption. Among them, the energy consumption of building doors and windows accounts for about 50% of the total building energy consumption. Converting, the energy consumption of building doors and windows accounts for about 15% of the total national energy consumption. Therefore, reducing the energy consumption of doors and windows is the most direct and efficient way to "save energy and reduce carbon". And the heat preservation performance (characterized by the heat transfer coefficient K value) and air tightness are two important physical properties of building doors and windows, which are related to each other and complement each other. That is, poor air tightness will seriously affect its heat preservation performance.

[0003] Currently, as shown in the attached Figure 1 The existing aluminum alloy broken bridge profile 1 is shown. The visible surface aluminum alloy profile body 101 on the indoor and outdoor sides is a high thermal conductivity material with a thermal conductivity coefficient of about 160 (W / (m•K)). The middle part is a thermoplastic composite material component 102 composed of nylon PA66 plus about 25% short glass fiber, and is composite by a strip-piercing and roll-pressing method; since the aluminum alloy broken bridge material needs to be provided with a metal transmission rod 103 around the middle of the profile to connect the translation execution component 104 after being made into doors and windows, such as: pulleys of a metal base, etc. Therefore, after the profile with a broken heat bridge is installed with metal hardware around, a continuous heat bridge is formed again. In fact, it does not achieve energy saving of doors and windows and cannot guarantee the heat insulation performance of doors and windows. Therefore, combined with the requirements of continuously increasing the heat transfer coefficient of doors and windows in various places, the aluminum alloy broken bridge system cannot be competent for triple-glazed insulating glass and large-span sliding doors and windows systems due to the too high thermal conductivity coefficient of the material and the insufficient stiffness of UPVC (plastic steel).

[0004] In addition, according to the different layouts and usage functions of buildings, doors and windows have opening methods such as inward opening, outward opening, sliding and pushing, etc. The space separation facilities between the building interior and the balcony mostly adopt the sliding and pushing method. In addition, in public places such as hospitals, nursing homes, kindergartens, schools and building parts such as escape passages, inward-opening windows will have potential safety hazards and unfavorable operations, etc. Sliding and pushing doors and windows will inevitably be used in these places. Among them, doors and windows with the inward-opening method mostly adopt multiple compressible ethylene propylene diene monomer rubber strips between the frame and the sash to achieve the sealing around the frame and the sash, thus better solving the heat preservation, air tightness and sound insulation of the window; while for sliding doors and windows, since the movement of the sash relies on the roller device (two or three groups, non-continuously distributed) to move axially along the frame track, there is a large gap between the frame and the sash. Even for the newly developed lift and slide door system, only the sliding sealing (not completely sealed) is carried out with rubber strips between the frame and the sash gaps. Such a solution cannot even meet the energy saving of doors and windows and the air tightness index greater than level 6 in regions such as Beijing-Tianjin-Hebei, Shanghai, Shandong, etc.

[0005] Therefore, there is an urgent need to design a door and window profile with good heat insulation performance and high airtightness, which can be applied to the use scenario with a large glass double-panel area. Summary of the Invention

[0006] The object of the present invention is to solve the problems of too high heat transfer coefficient of aluminum alloy broken bridge profiles and poor airtightness of sliding doors and windows in the prior art, and to provide a composite material door and window profile and a micro-side pressure door and window system processed by using the door and window profile, which can improve the heat insulation, heat preservation, airtightness and sound insulation of the doors and windows, and achieve energy saving of the doors and windows.

[0007] To achieve the above object, the present invention adopts the following technical solutions: A composite material door and window profile includes a composite profile main body, and the composite profile main body is formed by pultrusion process with a resin matrix composite material of fibers and / or fiber fabrics.

[0011] The present invention also discloses a micro-side-pressure door and window system including the above composite material door and window profiles. The micro-side-pressure door and window system is formed by jointly assembling and processing the composite profile body, the composite material frame, and the metal profiles and glass connected to both of them into door frames and / or door leaves, or window frames and / or window sashes. An profiles cover plate is provided on the left side of the composite profile body, and glass is provided on the upper middle support surface. The installation feet of the profiles cover plate are inserted into the grooves of the upper horizontal groove and are clamped. The composite profile body, the C-groove, the side-pressure translation member, the profiles cover plate, and the glass jointly constitute the translation door leaf and / or window sash in the micro-side-pressure door and window system. The composite material frame is made of a resin-based composite material of fibers and / or fiber fabrics through a pultrusion process. The non-visible surface inside is set as a continuous three-chamber or multi-chamber structure. The chamber structure is set as a closed structure in the radial direction and includes a side chamber and an intermediate chamber; the composite material frame includes a composite material border profile, a composite material upper frame profile, and a composite material lower frame profile of the same cross-section, as well as an independently composite composite material middle mullion profile. Among them, a concave frame groove for connecting a metal track is embedded and arranged downward on the upper side of the left side chamber of the composite material border profile, the composite material upper frame profile, and the composite material lower frame profile. An inclined water surface inclined to the right is provided above the middle chamber, and an L-shaped border is provided above the right side chamber; L-shaped borders are provided above and below one side chamber of the composite material middle mullion profile, and horizontal grooves with flush bottoms are provided above and below the other side chamber and the intermediate chamber.

[0012] Further, a metal side slideway is provided in the concave frame groove corresponding to the translation fan formed by the composite profile body on the composite material border profile. A sealing lock seat is connected to the end inside the metal side slideway. A manual or electric handle is provided outside the translation fan close to the border side. A sealing lock rod and a sealing angle actuator are also embedded in the C-groove of the translation fan close to the border side. A trapezoidal groove for cooperating with the sealing lock rod is provided in the sealing lock seat. The side-pressure movement and locking and sealing between the composite material border profile and the translation fan are completed through the cooperation connection between the side-pressure translation member and the sealing lock seat and the sealing lock rod.

[0013] Furthermore, a metal upper track is provided in the concave frame groove on the upper composite material frame profile corresponding to the translation fan formed by the composite profile body. A sealed upper pulley is slidably connected in the metal upper track, and the lower movable plate of the sealed upper pulley is cooperatively connected with the translation fan to complete sliding and lateral pressure movement.

[0014] Furthermore, a metal lower track is provided in the concave frame groove on the lower composite material frame profile corresponding to the translation fan formed by the composite profile body.

[0015] Furthermore, the composite material middle mullion profile is arranged parallel to the translation fan formed by the composite profile body, and the structural connection and positioning between the two are completed through a push-pull sealing hook lock arranged in the C groove of the translation fan.

[0016] Furthermore, at least one fireproof sealing rubber strip is provided on the non-visible surface and the glass contact surface between the composite material frame and the translation fan formed by the composite profile body. The fireproof sealing rubber strip adopts a compressible ethylene propylene diene monomer (EPDM) rubber strip.

[0017] The beneficial effects of the present invention are as follows: 1) In the present invention, a composite material with low thermal conductivity is used in the profile structure, and a wrapped broken bridge is formed through the design of a three-chamber structure, so that the entire profile heat channel is in a disconnected manner, reducing heat transfer, achieving an extremely low heat transfer coefficient and ultra-low energy consumption of the window, ensuring the heat insulation and heat preservation performance of the doors and windows, and realizing the energy conservation of the doors and windows; and a composite material frame is prepared by using the composite material. After the fan and the frame are cooperatively matched, the window frame wraps the independent support frame, forming a support for the translation fan surrounded by a frame compression sealing rubber strip for sealing. After the window fan is translated and locked, high sealing performance and noise reduction function of a casement window are achieved.

[0018] 2) In the composite door and window profile structure of the present invention, the required cross-section profile is made by the resin-based composite material pultrusion process. Utilizing the low thermal conductivity material characteristics of the composite material, the profile is a continuous low thermal conductivity material, and the thermal conductivity of this material is 0.34 (W / (m 2 ·K). First, the heat transfer coefficient of the frame is greatly reduced. With the high mechanical properties of the composite material, it is more suitable for the requirements of heavy-duty large-span sliding doors and windows. The three-chamber design is more conducive to frame assembly, avoiding the influence of foaming in one chamber on the implantation of the frame corner code. The large middle chamber is more suitable for energy conservation and fireproof foaming enhancement measures; among them, the metal profile is embedded in the composite material profile body in a mechanical snap connection manner. The entire profile heat channel is in a disconnected manner, reducing heat transfer and realizing mechanical functions. A complete fixed frame is implanted around the cooperation of the fan and the frame. High airtightness is achieved through the lateral micro-movement of the fan to compress the sealing rubber strip.

[0019] 3) In the system of the present invention, in addition to the translation function, when the door frame and / or door leaf, or window frame and / or window sash are closed in the plane, by rotating the door handle, a movement of 8-10 mm in the depth direction is pushed. By the way that the frame remains stationary while the sash moves and presses against the surrounding sealing rubber strips, high airtightness of the door and window system is achieved by relying on the elastic deformation of the sealing rubber strips.

[0029] As Figure 2 shown in the figure, a profile cover plate 5 is connected to the upper side position of the composite profile main body 2, and glass is installed on the upper middle support surface. The installation feet of the profile cover plate 5 are inserted into the grooves of the upper horizontal groove 206 and are clamped. The composite profile main body 2, the C groove 3, the side-pressure translation member 4, the profile cover plate 5, and the glass jointly constitute the translation door leaf and / or window leaf in the micro-side-pressure door and window system.

[0030] As Figure 3 shown in the figure, for the formed border and fan system, a metal side slideway 7 is installed in the concave frame groove corresponding to the translation fan formed by the composite profile main body 2 on the composite material border profile 601. A sealing lock seat 8 is connected to the end in the metal side slideway 7. A manual or electric handle is installed outside the translation fan close to the border side.

[0031] As Figure 4As shown in the figure, it is the upper frame and fan system formed. A metal upper track 10 is installed in the concave frame groove on the composite material upper frame profile 602 corresponding to the translation fan formed by the composite profile body 2. A sealed upper pulley 11 is slidably connected in the metal upper track 10. The lower movable plate of the sealed upper pulley 11 is cooperatively connected with the translation fan to complete sliding and lateral pressure movement.

[0032] As Figure 5 shown in the figure, it is the lower frame and fan system formed. A metal lower track 12 is installed in the concave frame groove on the composite material lower frame profile 603 corresponding to the translation fan formed by the composite profile body 2. The lateral pressure translation member 4 in the C groove 3 of the translation fan is cooperatively connected in the metal lower track 12 to complete sliding and lateral pressure movement.

[0033] As Figure 6 shown in the figure, it is the middle stile profile and fan system formed. The composite material middle stile profile 604 is arranged parallel to the translation fan formed by the composite profile body 2, and the structural connection and positioning between the two are completed through the push-pull sealing hook lock 13 connected in the C groove 3 of the translation fan. The structure of the push-pull sealing hook lock 13 is as Figure 8 shown.

[0034] At least one fireproof sealing strip 14 is provided on the non-visible surface and the glass contact surface between the composite material frame 6 and the translation fan formed by the composite profile body 2. The fireproof sealing strip 14 adopts a compressible ethylene propylene diene monomer (EPDM) rubber strip; when a fire and abnormal high temperature occur (60 - 80 °C), this fireproof sealing member blocks the gap with an expansion ratio of not less than 20 times to achieve the smoke prevention performance of the system.

[0035] The material of the metal lower track 12 and the C groove 3 is aluminum alloy, the material of the metal upper track 10 and the sealing lock seat 8 is galvanized carbon steel, and the material of the profile cover plate 5 and the push-pull sealing hook lock 13 is stainless steel.

[0036] Working principle: Since the frame system formed by the translation fan profiles composed of the composite profile body 2 is assembled with building energy-saving glass as a movable component, based on the different fittings of each component around the translation fan, the joint dimensions with the surrounding frame profiles are ensured to be unified. The frame is covered with a vertically continuous metal sealing lock seat, the lower frame is covered with a horizontally continuous metal lower track, the upper frame is covered with a horizontally continuous metal upper guide rail, the middle stile and the fan have a supporting relationship. The heights and forms of the functional metal materials covered by the frame are different, but they all have a continuous rectangle as a support for the sealing strip to be compressed, ensuring that the overlap amount between this support and the surrounding of the fan remains consistent.

[0037] Through the metal profile C groove 3 and the transmission rod system fixed on the translational sash composed of the composite profile body 2, the circular motion is converted into the linear motion of the transmission rod by rotating the handle. The transmission rod is connected to the sealing angle transmission device. The function of the angle transmission device is a sealing conversion mechanical device that can realize 90° linear motion. The transmission rod drives the sealing lock rod, the sealing upper pulley, the sealing lower pulley and other actuators located on the sash. Each actuator has its own serpentine slide. Driven by the transmission rod, the handle rotates to drive the transmission rod to move linearly and realize 8~10mm displacement perpendicular to the direction of the transmission rod through the serpentine slides of each actuator. The rubber strip designed for the translational door and window is a series of compressible EPDM rubber strip sealing systems, such as Figures 3 - 6 The compressible EPDM rubber strips at different positions shown in the circles work together, and the sash is driven by the above-mentioned execution hardware to produce lateral compression on the rubber strips. At this time, the frame is fixed, and the gaps around are completely compressed by the rubber strips to achieve double-channel sealing between the frame and the sash. After the window sash is translated and locked, the high sealing performance of the casement window is achieved.

[0038] The hardware in the composite door and window profile structure of the present invention is all installed on the non-visible surface of the composite profile body. The visible surface of the composite profile body is sprayed or coated to have a decorative effect, and the non-visible surface plays a role in the installation and bearing of the hardware. The multi-cavity of the profile body is responsible for assembling the frame, supporting the window body, and filling the flame-retardant or fire-proof foamed inorganic or organic fire-proof functions. The cavity can enhance the frame rigidity and improve the pulling force of the hardware connection through the built-in metal lining. After being connected with specific hardware, the system can realize the movement of translation and pushing and pulling. After the translation is closed, the transmission rod is driven by the lever principle of the handle to complete the lateral clamping force perpendicular to the translation direction, thereby realizing the high air tightness of the door and window system. The system of the present invention has low thermal conductivity, high air tightness and low carbon performance in the manufacturing process of the frame. The thermosetting composite material frame also ensures the fireproof performance of the sliding door.

[0039] The present invention uses a low thermal conductivity composite material in the profile structure and forms a wrapped broken bridge through a three-cavity design, so that the entire profile heat channel is in a disconnected mode to reduce heat transfer, achieve an extremely low heat transfer coefficient and ultra-low energy consumption of the window, ensure the thermal insulation and heat preservation performance of the doors and windows, and achieve energy saving of doors and windows; and use the composite material to prepare a composite material frame, and after the sash and the frame are matched, the independent supporting frame is covered by the door and window frame to form a support sealed by the same frame compression sealing strip around the sliding sash, and after the window sash is translated and locked, the high sealing and noise reduction function of the casement window is achieved.
