Description

Technical Field

[0001] The invention relates to the technical field of doors and windows, and more specifically to a multifunctional novel aluminum-wood composite door and window. Background Art

[0002] As part of modern architectural design, aluminum-wood composite doors and windows combine the beauty of natural wood with the structural strength of aluminum alloy, meeting the needs of building energy conservation, environmental protection and aesthetics. This type of door and window usually consists of an internal wood frame and an external aluminum alloy frame. The inner layer of wood adds a natural and warm atmosphere while providing good thermal insulation performance; the outer layer of aluminum alloy gives the door and window excellent weather resistance, corrosion resistance and easy maintenance. Structurally, aluminum-wood composite doors and windows use precise sealing technology, combined with multi-layer glass and thermal insulation strip design to achieve higher energy efficiency standards. This structural design not only ensures the firmness and sealing of the doors and windows, but also improves the sound insulation performance, making it popular in the market.

This not only damages the structure of the doors and windows themselves, but also affects the indoor environment and the comfort of users. In addition, the current aluminum-wood composite doors and windows are relatively simple in functionality and lack an effective monitoring mechanism to detect the sealing and integrity of doors and windows in real time. This means that once a problem occurs, the user may not be able to know it in the first time, thus missing the best time for maintenance, resulting in higher maintenance costs and maintenance difficulties.

[0027] An implementation of the present application is described in detail below with reference to the accompanying drawings.

[0028] Example:

[0029] See also Figure 1-Figure 3 A multifunctional new aluminum-wood composite door and window, comprising a door and window body 1, a wood layer 2, an aluminum alloy outer frame 3, an insulation strip 4 and a fixed frame 5. The door and window body 1 is composed of a wood layer 2, an aluminum alloy outer frame 3, a fixed frame 5 and a pair of insulation strips 4. The pair of insulation strips 4 are arranged in the middle of the wood layer 2 and the aluminum alloy outer frame 3, and the two ends of the pair of insulation strips 4 are respectively connected to the aluminum alloy outer frame 3 and the wood layer 2 close to one end. A heat-insulating glass 11 is arranged in the middle of the door and window body 1; the wood layer 2 is composed of an aluminum alloy inner frame and decorative wood. The material of the decorative wood is any one of oak, pine and walnut, and the outer surface of the decorative wood is coated with anti-corrosion. The outer surfaces of the aluminum alloy outer frame 3 and the aluminum alloy inner frame in the wood layer 2 are coated with a heat-insulating and anti-corrosion coating; a pair of heat-insulating strips 4 are filled with a heat-insulating filling layer 41, and a plurality of pairs of mutually symmetrical detection tubes 42 are installed at the bottom end of the upper heat-insulating strip 4 and in the heat-insulating filling layer 41, and a feedback shell 44 is installed in the middle of the pair of detection tubes 42 and at the bottom end of the upper heat-insulating strip 4, and a release capsule 45 is arranged in the feedback shell 44; the bottom ends of the fixed frame 5 are respectively connected to the wood layer 2 and the aluminum alloy outer frame 3, and the inner enclosure of the fixed frame 5 is connected to the outer enclosure of the heat-insulating glass 11, and a plurality of detection color-changing strips 51 are installed in the fixed frame 5.

[0030] Among them, this scheme adopts a modular structural design, which is mainly composed of a door and window body 1, a wood layer 2, an aluminum alloy outer frame 3, two pairs of insulation strips 4 and a fixed frame 5. Polyurethane foam is used as the insulation filling layer 41 to achieve insulation, and it also plays a role in gap filling, greatly improving the sealing performance of the doors and windows. When water seepage occurs in the insulation layer 41, the silica gel in the detection tube 42 absorbs rainwater, and the deformation rod 43 made of polyacrylamide expands and punctures the release capsule 45, releasing the remedial liquid 46 made of polyurethane sealant material, forming a waterproof layer in time, thereby reducing the risk of water damage to the structure. In addition, the broken elastic rope 47 at the top of the release capsule 45 triggers the pulling up of the detection color-changing strip 51 by reducing the tension, reflecting the release state of the remedial liquid. After waiting for the remedial liquid to be completely solidified, the degradable design of the oxidation fixing ring allows a pair of telescopic tubes to slide and fall, and the hydrophilic line allows moisture to migrate along the line to the detection color-changing strip 51 to change color to indicate water seepage, which is convenient for continued monitoring after remediation. Through the self-repair and continuous monitoring structural design, the service life of the doors and windows is extended, while the potential damage caused by water seepage is reduced, and the maintenance cost of the user is reduced.

[0031] The heat-insulating glass 11 is composed of multiple layers of glass, and the cavities formed by the multiple layers of glass are filled with inert gas.

[0032] Among them, inert gases such as argon and krypton have lower thermal conductivity than air. They can effectively reduce heat transfer through windows, so that indoor heat will not easily escape in winter, and outdoor heat will not easily enter the room in summer, thereby maintaining the indoor temperature stable. The combination of multi-layer glass and inert gas filling can lower the dew point on the inner surface of the glass and reduce the formation of condensation droplets caused by the temperature difference between indoor and outdoor, thereby maintaining a clear view of the window and preventing water vapor from damaging the window frame. At the same time, the density of inert gas is usually greater than that of air, which can more effectively absorb sound waves and reduce external noise.

[0033] See also Figure 4-Figure 6 The material of the heat-insulating filling layer 41 is set to polyurethane foam, the detection tube 42 is filled with silicone, a deformation rod 43 is installed on the inner wall of the detection tube 42, and a spike is installed at one end of the deformation rod 43. The material of the deformation rod 43 is set to polyacrylamide material, and the release capsule 45 is filled with a remedial liquid 46. The material of the remedial liquid 46 is set to polyurethane sealant. Puncture holes are opened at both ends of the feedback shell 44, and a diversion block is embedded at the bottom of the feedback shell 44. The deformation rod 43 passes through the puncture hole and extends to the inside of the feedback shell 44.

[0034] Among them, the material of the heat-insulating filling layer 41 is set to polyurethane foam material. Polyurethane foam is an excellent heat-insulating material. Its closed-cell structure can effectively prevent heat from being transferred through doors and windows, thereby improving the thermal insulation performance of the entire door and window system and reducing energy loss. The foam body formed by the polyurethane foam after curing can fill the gaps in the door and window frames, improve the air tightness and water tightness of the doors and windows, thereby reducing the penetration of air and moisture. At the same time, polyurethane foam has good sound absorption performance, which can reduce the impact of outdoor noise on the indoor environment and improve living comfort.

[0035] When rainwater enters the doors and windows during extreme weather or long-term use, the rainwater penetrates through the aluminum alloy frame 3 into the heat-insulating filling layer 41 arranged between a pair of heat-insulating strips 4. After the rainwater enters the heat-insulating filling layer 41, the closed cells inside it will be destroyed, causing the foam to absorb water. Since the thermal conductivity of water is higher than that of air, this will reduce the thermal insulation performance of the polyurethane foam. Long-term moisture erosion will cause the foam material to decompose or degrade, weakening the structural support it provides, thereby affecting the stability and service life of the doors and windows.

[0036] A detection tube 42 is provided at the bottom end of the upper insulation strip 4, and silica gel is provided in the detection tube 42. After rainwater enters the insulation filling layer 41, the silica gel provided in the detection tube 42 absorbs the rainwater entering the insulation filling layer 41. At the same time, a deformation rod 43 is provided in the detection tube 42. The material of the deformation rod 43 is set to polyacrylamide. Polyacrylamide is a common super absorbent polymer. After absorbing moisture on the silica gel, it expands rapidly, so that the spike installed at one end of the deformation rod 43 contacts the release capsule 45 and punctures the release capsule 45, so that the remedial liquid 46 in the release capsule 45 is released.

[0037] By setting the material of the remedial liquid 46 to a polyurethane sealant, the polyurethane-based sealant can be well combined with the existing foam and form a strong waterproof layer after curing, thereby remediating the failed sealing area that has been flooded, and finally achieving complete curing and final physical properties, which generally takes about seven to fourteen days.

[0038] A breaking elastic rope 47 is fixedly connected to the top of the release bag 45, and the breaking elastic rope 47 passes through the upper insulation strip 4 and extends into the fixed frame 5. The bottom end of the detection color changing strip 51 is fixedly connected to the breaking elastic rope 47, and the top of the detection color changing strip 51 is fixedly connected to a feedback elastic rope 52, and the top of the feedback elastic rope 52 is connected to the inner wall of the fixed frame 5. A pair of symmetrical transmission tubes 53 are fixedly connected to the top of the detection color changing strip 51, and a sealing cover 55 is provided at the bottom end of the transmission tube 53. Support ropes 54 and brittle rods 56 are respectively installed at both ends of the sealing cover 55, one end of the brittle rod 56 is connected to the inner wall of the fixed frame 5, and one end of the brittle rod 56 is connected to the breaking elastic rope 47.

[0039] The transmission tube 53 is composed of a pair of telescopic tubes, the inside of the pair of telescopic tubes is filled with hydrophilic thread, and an oxidation fixing ring is installed at the connection of the pair of telescopic tubes. The material of the hydrophilic thread is set to cotton thread, and the material of the oxidation fixing ring is set to degradable polymer.

[0040] Among them, after the remedial liquid 46 in the release capsule 45 is released, since the broken elastic rope 47 installed on the top of the release capsule 45 is connected to the detection color changing strip 51, after the remedial liquid 46 is released, the release capsule 45 reduces the pulling force on the detection color changing strip 51 through the broken elastic rope 47, and the detection color changing strip 51 is pulled up under the pulling force of the feedback elastic rope 52 on the detection color changing strip 51. At the same time, the brittle rod 56 breaks due to the inertia of the broken elastic rope 47, so that the sealing cover 55 loses its original supporting force and is separated from the transmission tube 53.

[0041] The fixed frame 5 is designed to be divided into two parts, namely, a transparent section and a shielding section. The shielding section is arranged on the lower side of the transparent section. When the detection color-changing strip 51 is not pulled up by the feedback elastic rope 52, it is in a shielded state. When the remedial fluid 46 in the release capsule 45 is released, the detection color-changing strip 51 can be observed. Such a design can feedback the release of the remedial fluid 46 in the release capsule 45 and the problem of water seepage in the area. At the same time, the sealing cover 55 loses its original supporting force and separates from the transmission tube 53. The transmission tube 53 is designed to be composed of a pair of telescopic tubes, and an oxidation fixing ring is installed at the connection of the telescopic tubes. The material of the oxidation fixing ring is set to a degradable polymer, such as polycaprolactone PCL, polylactic acid PLA or polyhydroxyalkanoate PHA. Under specific conditions, it can be designed to degrade within a few days to a few weeks. The degradation rate can be controlled by adjusting the molecular weight, additives and mixtures of the polymer.

[0042] Because the released remedial liquid 46 needs a period of time to solidify, and the telescopic cylinder is filled with hydrophilic thread, the material of the hydrophilic thread is set to cotton thread. If it is released directly, it will cause uncertainty in detection. It is necessary to wait for the released remedial liquid 46 to be completely solidified. At this time, after the oxidation is completed, a pair of telescopic cylinders begin to slide and enter the detection cylinder 42 for subsequent monitoring.

[0043] If water still seeps inside subsequently, the hydrophilic thread filled in the telescopic tube, which is made of cotton thread, is used as a naturally hydrophilic material to make water overcome gravity and move upward and enter the detection color-changing strip 51 set in the fixed frame 5. When the detection color-changing strip 51 comes into contact with water, it changes color, thereby reminding the user that water seepage has occurred and it needs to be repaired.

[0044] Working principle:

[0045] Insulation strips 4 are provided in the main body of the door and window, and polyurethane insulation filling layers 41 are provided between two pairs of insulation strips 4. In normal use of the door and window, the insulation filling layer 41 can effectively reduce the conduction of the heat source and achieve a good insulation effect. However, if used for a long time or in extreme weather, the insulation filling layer 41 may be affected by the penetration of rainwater.

[0046] When rainwater enters the heat-insulating filling layer 41, the silicone and the deformable rod 43 in the detection tube 42 arranged at the bottom end of the upper insulation strip 4 can quickly absorb and expand, and the sharp spikes of the deformable rod 43 will pierce the release capsule 45 located under the insulation strip 4. The release capsule 45 stores polyurethane sealant, which will be released once punctured. The released polyurethane sealant can be combined with the damaged polyurethane filling layer 41 to form a new waterproof layer, thereby repairing the water seepage area.

[0047] At the same time, since an elastic rope 47 is installed on the top of the release bag 45, and the elastic rope 47 is connected to the detection color changing strip 51, the release of the polyurethane sealant will also cause the detection color changing strip 51 to be pulled up, reminding the user that the remedial liquid has been released. After complete solidification, the telescopic cylinder 53 arranged in the detection cylinder 42 will slide into the detection cylinder 42 after the fixing ring is degraded. If there is still water seepage in the future, the hydrophilic cotton thread will lead the water to the color changing strip 51, and issue a secondary water seepage warning. Through such self-repair and continuous monitoring design, the service life of doors and windows can be greatly extended and the safety of use can be guaranteed.
