Description

Technical Field

[0001] This utility model relates to the field of thermally broken aluminum profiles, and more particularly to a thermally broken aluminum-plastic co-extruded profile structure. Background Technology

[0002] Thermally broken aluminum profiles are widely used in doors, windows, curtain walls and other fields due to their excellent thermal insulation and sound insulation properties. Traditional thermally broken aluminum profiles typically employ a mechanical composite structure of "aluminum profile + thermal break strip." This involves embedding thermal insulation materials such as nylon PA66 into the thermal break groove of the aluminum profile through a strip insertion or adhesive injection process. This achieves physical separation between the inner and outer parts of the aluminum profile, blocking the heat conduction path. However, during the installation of thermally broken aluminum windows onto the window frame, errors in building construction can result in unevenness at the bottom of the window. Therefore, leveling the window is necessary during installation, which increases the difficulty of installation. Furthermore, the cavity located on the exterior of the thermally broken aluminum profile structure is susceptible to condensation due to large temperature differences between day and night. The condensed water droplets accumulate in the cavity and cannot drain, potentially affecting the sealing and insulation performance of the thermally broken aluminum profile over time. Therefore, a co-extruded thermally broken aluminum profile structure is needed to address the challenges of installation and the inability to timely expel condensation caused by large temperature differences, thus improving the sealing effect of the thermally broken aluminum profile. Utility Model Content

[0003] In response to the above situation and to overcome the shortcomings of the existing technology, this device provides a thermal break aluminum-plastic co-extruded profile structure. This device effectively reduces the difficulty of installing thermal break aluminum-plastic windows, while preventing water vapor from condensing inside the thermal break cavity, thus improving the sealing and thermal insulation properties of the thermal break aluminum-plastic profile.

[0004] The purpose of this utility model is to provide a thermal break aluminum-plastic co-extruded profile structure, including thermal break aluminum, with two thermal insulation cavities inside the thermal break aluminum, and a thermal insulation strip snapped between the two thermal insulation cavities. The top of the thermal break aluminum has two glass mounting grooves, and sealing strips are snapped into the mounting grooves respectively. An outer stop block is snapped into the front end of the thermal break aluminum, and two water-proof cavities are opened in the outer stop block. The two water-proof cavities are distributed vertically, and multiple drainage holes are opened at the bottom of the two water-proof cavities respectively. A mounting base is snapped into the bottom of the thermal break aluminum, and multiple adjusting bolts for window leveling are connected to the bottom of the mounting base.

[0005] Furthermore, multiple heat insulation grooves are provided inside the heat insulation strip.

[0006] Furthermore, the sealing strip can be U-shaped, with protrusions on both sides of the mounting groove, and slots fixedly connected to the outer side of the sealing strip, with the protrusions and slots engaging with each other.

[0007] Furthermore, a dovetail groove is provided on the front surface of the thermally broken aluminum, and a dovetail block is fixedly connected to the rear end of the outer stop block, with the dovetail groove and the dovetail block interlocking with each other.

[0008] Furthermore, a first locking block is fixedly connected to the top of the mounting base, and a second locking block is fixedly connected to the bottom of the thermally broken aluminum base. The first and second locking blocks are interlocked with each other, and a sound-insulating strip is fixedly connected to the gap between the top of the first locking block and the second locking block.

[0009] Furthermore, multiple water-conducting blocks are arranged in parallel within the water-proof cavity to facilitate water vapor condensation.

[0010] Furthermore, multiple positioning holes are arranged parallel to each other on the bottom of the mounting base.

[0011] Furthermore, the bottom of the mounting base is fixed with multiple threaded holes, and multiple adjusting bolts are threadedly connected to the corresponding threaded holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Compared with the prior art, the present invention can effectively block external water vapor through the outer baffle, and at the same time, the water vapor condensed in the cavity can be discharged by using the water-proof cavity, water-guiding block and drainage hole, thereby improving the water-proof effect of the thermally broken aluminum profile.

[0014] 2. Compared with the prior art, this utility model facilitates window leveling during window frame installation by using multiple adjusting bolts at the bottom of the mounting base, reducing installation difficulty. At the same time, the installation of heat insulation strips and sound insulation strips between the thermal break aluminum profiles effectively improves the heat insulation and sound insulation effect of the thermal break aluminum profile.

[0020] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0021] according to Figures 1 to 4 As shown, a thermally broken aluminum-plastic co-extruded profile structure includes a thermally broken aluminum profile 1. Two thermal insulation cavities 2 are formed within the thermally broken aluminum profile 1, and a thermal insulation strip 6 is snapped between the two thermal insulation cavities 2. Two glass mounting grooves are formed at the top of the thermally broken aluminum profile 1, and sealing strips 3 are snapped into each of the mounting grooves. An outer stop block 4 is snapped into the front end of the thermally broken aluminum profile 1, and two water-proof cavities 15 are formed within the outer stop block 4. The two water-proof cavities 15 are arranged vertically, and multiple drainage holes 17 are formed at the bottom of each of the two water-proof cavities 15. A mounting base 5 is snapped into the bottom of the thermally broken aluminum profile 1, and multiple adjusting bolts 20 for window leveling are connected to the bottom of the mounting base 5.

[0022] In practical implementation, the thermally broken aluminum 1 has two heat insulation chambers 2, which are arranged parallel to each other, and a heat insulation strip 6 is snapped between the two heat insulation chambers 2. The two parallel heat insulation chambers 2, running from the outside to the inside, can effectively isolate external heat. At the same time, the heat insulation strip 6 further separates the two heat insulation chambers 2, further improving the heat insulation effect. Glass can be installed in the two mounting grooves on the top of the thermally broken aluminum 1, realizing the installation of two panes of glass. This facilitates the later extraction of air between the two panes of glass to create a hollow effect, thereby improving the sound insulation effect. The sealing strip 3 can... To increase the sealing between the glass and the mounting groove and improve waterproofing, the bottom of the outer block 4 is provided with an outward sloping slope. The slope can prevent rainwater from accumulating on the top of the outer block 4. The two vertically arranged water-proof cavities 15 inside the outer block 4 can easily condense water vapor and discharge it through the drainage hole 17 when there is a large temperature difference between day and night and high humidity. The multiple adjusting bolts 20 at the bottom of the mounting base 5 can be adjusted according to the horizontal height of the bottom of the window to ensure that the thermally broken aluminum profile window frame can be installed horizontally on the window, reducing the installation difficulty of the thermally broken aluminum profile window frame.

[0023] Furthermore, multiple heat insulation grooves 9 are provided inside the heat insulation strip 6.

[0024] In practical implementation, the multiple thermal insulation grooves 9 opened in the thermal insulation strip 6 can further increase the thermal insulation effect of the thermal insulation strip 6, thereby improving the thermal insulation effect of the window frame of the thermally broken aluminum profile.

[0025] Furthermore, the sealing strip 3 can be set as U-shaped, with protrusions 8 on both sides of the mounting groove, and slots 7 fixedly connected to the outer side of the sealing strip 3, with the protrusions 8 and slots 7 engaging with each other.

[0026] In practical implementation, the U-shaped sealing strip 3 can improve the sealing performance of the glass when connected to the thermally broken aluminum-plastic profile window frame, and the snap-fit ​​of the protrusion 8 and the groove 7 facilitates the installation of the thermal insulation strip 6 on the top of the thermally broken aluminum-plastic profile window frame.

[0027] Furthermore, a dovetail groove 14 is provided on the front surface of the thermally broken aluminum 1, and a dovetail block 13 is fixedly connected to the rear end of the outer stop block 4. The dovetail groove 14 and the dovetail block 13 are interlocked with each other.

[0028] In specific implementation, two dovetail grooves 14 and dovetail blocks 13 can be set, and the two dovetail grooves 14 and dovetail blocks 13 are respectively arranged laterally on the front end surface of the thermally broken aluminum 1 and the rear end surface of the outer baffle 4. The combination of dovetail grooves 14 and dovetail blocks 13 facilitates the installation of the outer baffle 4 on the front end surface of the thermally broken aluminum 1.

[0029] Furthermore, a first locking block 10 is fixedly connected to the top of the mounting base 5, and a second locking block 11 is fixedly connected to the bottom of the thermally broken aluminum 1. The first locking block 10 and the second locking block 11 are interlocked with each other, and a sound-insulating strip 12 is fixedly connected to the gap between the top of the first locking block 10 and the second locking block 11.

[0030] In practice, the first locking block 10 and the second locking block 11 are interlocked to facilitate the installation of the mounting base 5 and the thermally broken aluminum 1. The gap between the top of the first locking block 10 and the second locking block 11 is filled with sound-insulating strips 12, which can increase the sound insulation effect of the mounting base 5 on the thermally broken aluminum 1.

[0031] Furthermore, multiple water-guiding blocks 16 are arranged in parallel inside the water-proof cavity 15 to facilitate water vapor condensation.

[0032] In practical implementation, the bottom of the water-proof cavity 15 is provided with an outward sloping slope, and the drainage channel is located at the lowest point of the slope. The water-guiding block 16 facilitates the condensation of water vapor into water droplets at the lowest point of the water-proof cavity 15 when the air humidity is high. Then, the condensed water droplets are discharged from the water-proof cavity 15 through the drainage outlet, which effectively avoids the water vapor from condensing into water droplets in the cavity of the thermally broken aluminum profile window frame due to excessive air humidity, thus affecting the quality of the thermally broken aluminum profile window frame.

[0033] Furthermore, the mounting base 5 has multiple positioning holes 18 arranged parallel to each other on its bottom.

[0034] In practice, when installing the thermally broken aluminum-plastic profile window frame, multiple positioning pins can be set at the bottom of the window. Then, the multiple positioning holes 18 at the bottom of the mounting base 5 are aligned with the positioning pins for installation, which improves the installation accuracy of the thermally broken aluminum-plastic profile window frame.

[0035] Furthermore, the bottom of the mounting base 5 is fixedly provided with multiple threaded holes 19, and multiple adjusting bolts 20 are threadedly connected to the corresponding threaded holes 19 respectively.

[0036] In practical implementation, when leveling the window frame of the thermally broken aluminum profile, the distance of rotation of the adjusting bolt 20 in the threaded hole 19 can be adjusted according to the height difference of the window. By adjusting the depth of the threaded connection of multiple adjusting bolts 20 in the threaded hole 19, the mounting base 5 can be installed horizontally in the window. This avoids the need for workers to temporarily use wooden blocks to raise the window frame of the thermally broken aluminum profile due to the height difference of the window, reduces the difficulty of installing the window frame of the thermally broken aluminum profile, and improves the efficiency of the installation.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
