Description

Technical Field

[0001] The utility model relates to the technical field of door and window profiles, in particular to an impact-resistant and strengthened aluminum-plastic door and window profile. Background Art

[0002] With the continuous improvement of the quality of life, in the cold winter, people have higher and higher requirements for the indoor temperature, and the heat preservation effect of door and window profiles is becoming more and more important. At present, there are many disadvantages in the heat preservation door and window profiles applied in the construction industry in China. Generally, an inner profile and an outer profile form a cavity through a heat insulation cold bridge to achieve the heat preservation effect. However, most of the cold and hot air will still be conducted to the inner profile through the middle cavity, resulting in a sharp decline in the indoor heat preservation effect. In addition to poor heat preservation performance, the airtightness is reduced, the heat loss is fast, the energy-saving effect is low, and the air penetration and even rain penetration are likely to cause the aging and deformation of the door and window profiles, thus reducing the service life of the door and window profiles, increasing the economic pressure on people, and causing resource waste at the same time.

[0003] In the Chinese utility model patent with the publication number of CN203515184U, an aluminum-plastic composite door and window profile is disclosed, which includes an inner profile and an outer profile. The inner profile and the outer profile are connected through a first heat insulation cold bridge and a second heat insulation cold bridge. A cavity is formed between the first heat insulation cold bridge and the second heat insulation cold bridge. A heat insulation strip is fixedly connected to the middle parts of the first heat insulation cold bridge and the second heat insulation cold bridge. The heat insulation strip divides the cavity into an inner cavity and an outer cavity. The beneficial effects of the utility model are as follows: while the inner profile and the outer profile are composite, the cavity formed by the heat insulation cold bridge is divided into two inner and outer cavities. This structure more effectively blocks the alternation of cold and hot air. At the same time, the strength of the composite profile is also greatly increased, and the advantages of the heat insulation door and window are given full play, saving more energy resources and having strong practicability.

[0004] In view of the above related technologies, the inventor believes that there are the following defects: the above device blocks heat by connecting a heat insulation strip between the first heat insulation cold bridge and the second heat insulation cold bridge, and the heat preservation performance of the profile is slightly improved compared with the traditional method. However, in actual use, due to the relatively thin thickness of both the heat insulation strip and the heat insulation cold bridge, the sound insulation effect at the connection of the two profiles is poor, and it is easy to cause the sound waves blocked by the sound insulation glass to directly pass through the connection of the two profiles, resulting in a poor use experience. Summary of the Utility Model

[0005] In order to solve the above problems, the utility model provides an impact-resistant and strengthened aluminum-plastic door and window profile.

[0006] The above technical object of the utility model is achieved by the following technical solutions: An impact-resistant and strengthened aluminum-plastic door and window profile, including an inner profile and an outer profile. On the side walls of the inner profile and the outer profile close to each other, two T-shaped grooves are respectively opened. A heat insulation cold bridge is slidably arranged in two opposite T-shaped grooves. An aluminum profile is wrapped on the inner profile and the outer profile. A barrier layer for sound insulation is filled between the two heat insulation cold bridges.

[0007] By adopting the above technical solutions, the barrier layer consists of three layers. The heat insulation layer in the middle directly abuts against the two heat insulation cold bridges, thereby reducing the probability of heat transfer between the inner profile and the outer profile, and further improving the heat preservation effect of the inner profile and the outer profile. In addition, the first sound insulation layer and the second sound insulation layer on both sides of the heat insulation layer weaken the transmitted sound waves in sequence, thereby reducing the probability of indoor personnel being affected by noise, and thus improving the use experience of the staff.

[0008] Furthermore, the barrier layer includes a first sound insulation layer arranged on the side wall of one heat insulation cold bridge, a second sound insulation layer arranged on the side wall of the other heat insulation cold bridge, and a heat insulation layer jointly installed on the side walls of the two heat insulation cold bridges close to each other.

[0009] Furthermore, filling layers are arranged on the inner walls of the inner profile and the outer profile.

[0010] By adopting the above technical solutions, since the inner profile and the outer profile are both made of aluminum metal, some heat is easily accumulated in the inner profile and the outer profile. The filling layer reduces the probability of heat loss, thereby being beneficial to reducing the loss of indoor temperature, and further improving the heat preservation effect of the inner profile and the outer profile.

[0011] Furthermore, the filling layer is a filling layer made of polyurethane foam adhesive.

[0012] By adopting the above technical solutions, the full name of polyurethane foam adhesive is one-component polyurethane foam sealant, commonly known as foaming agent, foaming glue, PU sealant. Its English name is PU FOAM, which is the product of the cross-combination of aerosol technology and polyurethane foam technology. The cured foam has functions such as caulking, bonding, and sealing. In addition, the flame-retardant polyurethane foaming agent can reach Class B and Class C flame retardancy, and its service life is not less than ten years. The filling layer made of polyurethane foam adhesive has good use effects at different temperatures, long service life, and good use experience.

[0013] Furthermore, on the side walls of the two heat insulation cold bridges away from each other, placement rods are respectively fixed. On the two opposite inner walls of the aluminum profile, placement grooves matching the placement rods are respectively opened.

[0014] By adopting the above technical solution, the two mounting rods are directly connected to the aluminum profiles, thereby improving the stability of the heat insulation cold bridge. Furthermore, when the inner profile is subjected to external impact, the probability of irreversible deformation of the heat insulation cold bridge is reduced, thus improving the impact resistance of the inner profile and the outer profile.

[0015] Furthermore, the heat insulation cold bridge is a heat insulation cold bridge made of reinforced glass fiber nylon 66, and the mounting rod is a mounting rod made of reinforced glass fiber nylon 66.

[0016] By adopting the above technical solution, with the continuous development and needs of industrial production, plastic modified products play an increasingly important role in the plastic industry. In plastic modification, physical filling of glass fiber reinforced materials has high tensile strength, dimensional stability, heat resistance and good electrical properties. The mounting rod made of reinforced glass fiber nylon 66 has good heat insulation effect, which can effectively block the heat and cold conduction between indoors and outdoors, thus improving the heat preservation effect of the inner profile and the outer profile.

[0017] Furthermore, the first sound insulation layer abuts against one of the heat insulation cold bridges, and the second sound insulation layer abuts against the other heat insulation cold bridge.

[0018] By adopting the above technical solution, the first sound insulation layer and the second sound insulation layer are staggered, effectively blocking the transmission of sound waves, thereby bringing the sound insulation performance of the inner profile and the outer profile to a new height, and further improving the use experience of the staff.

[0019] Furthermore, the heat insulation layer is a heat insulation layer made of polymer composite micro-foamed polyvinyl chloride material, and the first sound insulation layer is a first sound insulation layer made of micro-foamed glass fiber PVC.

[0020] By adopting the above technical solution, the polyvinyl chloride material made by the micro-foaming technology has good heat insulation effect and excellent service life, thus further blocking the heat and cold conduction between indoors and outdoors, and then improving the heat preservation performance of the inner profile.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, the barrier layer consists of three layers. The heat insulation layer in the middle directly abuts against the two heat insulation cold bridges, thereby reducing the probability of heat transfer between the inner profile and the outer profile, and further improving the heat preservation effect of the inner profile and the outer profile. In addition, the first sound insulation layer and the second sound insulation layer on both sides of the heat insulation layer weaken the transmitted sound waves in turn, thereby reducing the probability of indoor personnel being affected by noise, and thus improving the use experience of the staff;

[0023] 2. In this application, since both the inner profile and the outer profile are made of aluminum metal, some heat is likely to accumulate inside the inner profile and the outer profile. The filling layer reduces the probability of heat loss, which is beneficial to reducing the loss of indoor temperature and thus improving the heat insulation effect of the inner profile and the outer profile.

[0024] 3. In this application, the full name of the polyurethane foam adhesive is one-component polyurethane foam sealant, commonly known as foaming agent, foaming glue, and PU sealant. Its English name is PU FOAM, which is a product of the cross-combination of aerosol technology and polyurethane foam technology. The cured foam has functions such as caulking, bonding, and sealing. In addition, the flame-retardant polyurethane foaming agent can reach Class B and Class C flame retardancy, and its service life is not less than ten years. The filling layer made of polyurethane foaming glue has good use effects at different temperatures, a long service life, and a good user experience. Brief Description of the Drawings

[0030] The barrier layer 5 is filled between two heat-insulating cold bridges 3 for sound insulation. The barrier layer 5 includes a first sound-insulating layer 51, a second sound-insulating layer 52, and a heat-insulating layer 53. The first sound-insulating layer 51 is disposed on the side wall of one of the heat-insulating cold bridges 3 and is made of micro-foamed glass fiber PVC. The second sound-insulating layer 52 is disposed on the side wall of the other heat-insulating cold bridge 3 and is made of micro-foamed glass fiber PVC. The heat-insulating layer 53 is commonly installed on the side walls of the two heat-insulating cold bridges 3 close to each other and is made of a polymer composite micro-foamed polyvinyl chloride material.

[0031] The polyvinyl chloride material made by the micro-foaming technology has good heat-insulating effect and excellent service life, thus further blocking the heat and cold conduction between indoors and outdoors, and then improving the heat preservation performance of the inner profile 1.

[0032] There are multiple filling layers 6 which are respectively disposed on the inner walls of the inner profile 1 and the outer profile 11, and the filling layer 6 is made of polyurethane foam adhesive. Since both the inner profile 1 and the outer profile 11 are made of aluminum metal, some heat is likely to accumulate in the inner profile 1 and the outer profile 11. The filling layer 6 reduces the probability of heat loss, which is beneficial to reducing the loss of indoor temperature, and then improving the heat preservation effect of the inner profile 1 and the outer profile 11.

[0033] The full name of the polyurethane foam adhesive is one-component polyurethane foam sealant, commonly known as foaming agent, foaming glue, and PU sealant. The English name is PU FOAM, which is the product of the cross-combination of aerosol technology and polyurethane foam technology. The cured foam has functions such as caulking, bonding, and sealing.

There are two placement rods 7 which are respectively disposed on the side walls of the two heat-insulating cold bridges 3 away from each other, and placement grooves 8 matching the placement rods 7 are formed on the two opposite inner walls of the aluminum profile 4. The two placement rods 7 are directly connected to the aluminum profile 4, thus improving the stability of the heat-insulating cold bridge 3, and then reducing the probability of irreversible deformation of the heat-insulating cold bridge 3 when the inner profile 1 is subjected to external impact, thereby improving the impact resistance of the inner profile 1 and the outer profile 11.

[0035] In order to improve the heat insulation effect of the inner profile 1 and the outer profile 11, the heat insulation cold bridge 3 is made of reinforced glass fiber nylon 66, and the placement rod 7 is made of reinforced glass fiber nylon 66. With the continuous development and needs of industrial production, plastic modified products play an increasingly important role in the plastic industry.

The placement rod 7 made of reinforced glass fiber nylon 66 has a good heat insulation effect, which can effectively block the heat conduction between indoors and outdoors, thus improving the heat insulation effect of the inner profile 1 and the outer profile 11.

[0036] In order to improve the working experience of the staff, the first sound insulation layer 51 abuts against one of the heat insulation cold bridges 3, and the second sound insulation layer 52 abuts against the other heat insulation cold bridge 3. The first sound insulation layer 51 and the second sound insulation layer 52 are staggered, effectively blocking the transmission of sound waves, thereby making the sound insulation performance of the inner profile 1 and the outer profile 11 reach a new level, and further improving the working experience of the staff.

[0037] The working principle of an impact-resistant and strengthened aluminum-plastic door and window profile in this embodiment is as follows: The barrier layer 5 consists of three layers. The heat insulation layer 53 in the middle directly abuts against the two heat insulation cold bridges 3, thereby reducing the probability of heat transfer between the inner profile 1 and the outer profile 11, and further improving the heat insulation effect of the inner profile 1 and the outer profile 11. In addition, the first sound insulation layer 51 and the second sound insulation layer 52 on both sides of the heat insulation layer 53 weaken the transmitted sound waves in sequence, thereby reducing the probability of indoor personnel being affected by noise, and thus improving the working experience of the staff.
