Description

Technical Field

[0001] This utility model relates to door and window profiles, specifically to a modular thermal insulation aluminum alloy door and window structure. Background Technology

[0002] Insulated aluminum alloy doors and windows are constructed by using low-thermal-conductivity nylon thermal break strips to split the aluminum profile in the middle, creating two parts: an indoor section and an outdoor section. This effectively blocks heat transfer. In winter, aluminum alloy doors and windows need to have good insulation performance to prevent indoor heat from being transferred to the outside through gaps or the material itself, thus maintaining a stable indoor temperature and improving living comfort. In summer, strong solar radiation can significantly raise outdoor temperatures. If doors and windows do not have good insulation, a large amount of heat will enter the room, causing indoor temperatures to rise, increasing energy consumption for air conditioning and other cooling equipment, and reducing living comfort.

[0003] The following are existing technologies related to the structure of thermally insulated aluminum alloy doors and windows:

[0004] Referring to Chinese patent, publication number: CN217461866U, a passive thermal break aluminum alloy door and window insulation core structure is disclosed.

[0005] Referring to Chinese Patent Publication No. CN110043159A, a passive window and door insulation material, its preparation method, and a passive window and door are disclosed.

[0006] In the existing technologies, including the two patents mentioned above, traditional aluminum alloy door and window structures achieve thermal insulation mainly by forming cavities during the assembly of aluminum alloy window profiles. These cavities create an independent sealed space, thereby achieving a certain degree of thermal insulation. However, air temperature exchange still occurs, which is unavoidable. How to further reduce the temperature of this exchange is a question that needs to be addressed effectively. Utility Model Content

[0028] like Figure 1 As shown, a modular thermal insulation aluminum alloy door and window structure includes:

[0029] 1. Flame-retardant preform for polypropylene spinning grade;

[0030] The first aluminum alloy sheet 2 is assembled on both sides of the polypropylene spinning-grade flame-retardant preform 1, and both ends extend to the outside of the polypropylene spinning-grade flame-retardant preform 1 to form an upper part 21 and a lower part 22 respectively.

[0031] The upper cover 5 is assembled with the two upper connecting parts 21 as one piece;

[0032] The lower cover 6 is assembled with the two lower connecting parts 22 as one piece.

[0033] The second aluminum alloy sheet metal part 3 has a hook groove part 31 symmetrically fixed on one side. The upper cover 5 and the lower cover 6 have hook groove parts 100 that are inserted into the hook groove parts 31 fixed at both ends. The second prefabricated flame retardant part 4 is fixed between the two hook groove parts 31.

[0034] Specifically, in the above embodiment, the upper cover 5 and the lower cover 6 are used to limit the symmetrically distributed first aluminum alloy sheet metal parts 2, thereby forming a first space between the two first aluminum alloy sheet metal parts 2, the upper cover 5, and the lower cover 6, and the polypropylene spinning-grade flame-retardant prefabricated part 1 is located in the first space. Then, the hook groove 31 of the second aluminum alloy sheet metal part 3 is inserted into the hook groove 100 at the end of the upper cover 5 and the lower cover 6, thereby maintaining a predetermined space, i.e., a second space, between the second aluminum alloy sheet metal part 3 and the first aluminum alloy sheet metal part 2, and the second prefabricated flame-retardant part 4 is located in the second space.

[0035] It should be noted that the aforementioned polypropylene spinning-grade flame-retardant prefabricated part 1 is a polypropylene spinning-grade flame-retardant plastic part. The second prefabricated flame-retardant part 4 is a convex flame-retardant cotton structure, and according to the structure, it is divided into long rectangles and short rectangles, with the long rectangles conforming to the surface distribution of the second aluminum alloy sheet material part 3.

[0036] Secondly, the polypropylene spinning-grade flame-retardant preform 1 has a hollow structure, and the hollow structure is rectangular.

[0037] The above-mentioned combination of the first aluminum alloy sheet material 2 and the second aluminum alloy sheet material 3 makes the aluminum alloy door and window a double-layer profile on one side, forming a double-layer sealed space. Then, polypropylene spinning-grade flame-retardant prefabricated component 1 and the second prefabricated flame-retardant component 4 are respectively placed in the double-layer sealed space, thereby improving the fire resistance coefficient of the aluminum alloy door and window while also playing a role in heat insulation.

[0038] As a further embodiment of this utility model, this example aims to provide a method for combining polypropylene spinning-grade flame-retardant preform 1 and polypropylene spinning-grade flame-retardant preform 1. The detailed structure is as follows: the outer wall of the polypropylene spinning-grade flame-retardant preform 1 is provided with a first isosceles trapezoidal groove 11, and the side wall of the first aluminum alloy sheet 2 is fixedly provided with a first inlay 23 that is inserted and cooperates with the first isosceles trapezoidal groove 11.

[0039] As a further embodiment of this utility model, this example aims to provide a method for combining the upper connecting part 21 and the lower connecting part 22 with the upper cover 5 and the lower cover 6. The detailed structure is as follows: the upper connecting part 21 and the lower connecting part 22 are each provided with a second isosceles trapezoidal groove 200. The upper cover 5 and the lower cover 6 are each symmetrically provided with vertical parts 101 distributed vertically. The two vertical parts 101 are attached to the wall of the two upper connecting parts 21 and the two lower connecting parts 22 on the adjacent side. The side of the two vertical parts 101 is fixedly provided with a second inlay 102 inserted into the second isosceles trapezoidal groove 200.

[0040] As a further embodiment of the present invention, the end of the second aluminum alloy sheet 3 located outside the upper cover 5 is an extension 32, and a glass fixing groove is formed between the two extensions 32.

[0041] As a further embodiment of this utility model, the connection end between the second aluminum alloy sheet 3 and the lower cover 6 is an inclined end, and the inclined ends of the two symmetrical second aluminum alloy sheet 3 in the cross section are the sides of an isosceles trapezoid.

[0042] Specifically, by increasing the width of the outer contour of aluminum alloy doors and windows, the overall load-bearing capacity of the aluminum alloy doors and windows is increased, thereby increasing their fire resistance in the event of a fire.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
