Description

Technical Field

[0001] This utility model relates to the field of building sealing technology, and in particular to an embedded adjustable sealing connection structure for building aluminum profiles, which is suitable for the connection and sealing of aluminum profiles in curtain walls, doors and windows, and prefabricated facade systems. Background Technology

[0002] In existing curtain wall or window systems, aluminum profiles typically achieve airtightness, watertightness, and thermal insulation through sealing strips. Traditional sealing strips mostly employ a fixed, embedded installation structure, with their clamping force depending on the pre-existing structural dimensions and the deformation of the rubber material. However, dimensional tolerances can easily occur in building components during transportation, installation, or operation. Insufficient clamping of the sealing strip will lead to air leakage and water ingress; conversely, excessive clamping will affect assembly and subsequent replacement.

[0003] Some systems use double seals or multiple pressure strips to improve the sealing effect, but due to their complex structure and difficulty in adjustment, they cannot flexibly adapt to different gap scenarios, especially under complex node or on-site error conditions.

[0004] Therefore, there is an urgent need for a new type of sealing connection structure that is simple in structure, has adjustable clamping force, and can adapt to various assembly deviations, so as to improve the adaptability, sealing reliability and maintenance convenience of building systems. Utility Model Content

[0005] The purpose of this invention is to provide an embedded adjustable sealing connection structure for architectural aluminum profiles to solve the problems mentioned in the background art.

[0006] An embedded adjustable sealing connection structure for architectural aluminum profiles includes an aluminum profile body, a groove, a sealing strip, and a clamping adjustment mechanism.

[0007] The groove is provided on the aluminum profile body for embedding and installing the sealing strip;

[0008] The clamping adjustment mechanism is located on one side or at the bottom of the groove and is used to adjust the clamping force between the sealing strip and the mating component;

[0009] The clamping adjustment mechanism includes a limiting slider, an elastic element and an adjusting screw. The adjusting screw (133) is threadedly connected to the limiting slider, and the elastic element is disposed between the limiting slider and the aluminum profile body.

[0010] Furthermore, the sealing strip is made of soft elastic rubber or TPV material, and its outer wall is interference-fitted with the inner wall of the groove.

[0011] Furthermore, the limiting slider is provided with a protrusion that cooperates with the limiting groove to prevent the slider from shifting in a non-adjustment direction.

[0012] Furthermore, the adjusting screw passes through the mounting hole on the aluminum profile body and can be rotated and adjusted from the outside of the profile.

[0013] Furthermore, the elastic element is a compression spring, a wave washer, or a rubber pad, used to provide a reset thrust.

[0014] Furthermore, multiple clamping adjustment mechanisms are provided and arranged at intervals along the length of the sealing strip.

[0015] Furthermore, the sealing strip has a cavity structure, which is used to absorb tolerance changes during deformation under compression.

[0016] Furthermore, the adjusting screw is an internal hex head screw, which is convenient for adjustment with standard tools during on-site construction.

[0017] Furthermore, the mating component is made of glass, metal strip, or other aluminum profile components, and forms a sealing surface in contact with the sealing strip.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This embedded adjustable sealing connection structure for architectural aluminum profiles adopts an adjustable clamping structure, which can adjust the clamping force of the sealing strip within a range of ±2mm or more. It effectively absorbs the gap changes caused by profile assembly tolerances, thermal expansion and contraction or structural deformation, thereby achieving stable output of sealing performance under different installation conditions and significantly improving the consistency of the system's air tightness, water tightness and sound insulation performance.

[0020] 2. This embedded adjustable sealing connection structure for architectural aluminum profiles features an embedded adjustment mechanism that offers advantages such as compact structure, easy assembly, and on-site tool adjustment. It allows for fine-tuning of the sealing tightness during construction, meeting the diverse assembly requirements of complex nodes. Furthermore, the main profile can be replaced or adjusted without disassembling it, significantly improving system installation efficiency and maintenance convenience, and extending service life.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 5 As shown, an embedded adjustable sealing connection structure for building aluminum profiles mainly includes an aluminum profile body (100), a groove (110), a sealing strip (120), and a pressing adjustment mechanism (130).

[0029] I. Structure of the groove and sealing strip

[0030] The groove (110) is provided on the upper surface of the aluminum profile body (100) and has a "T" or "C" shaped cross-section. The bottom of the groove and the side wall are respectively provided with guide grooves and limiting edges for accurately positioning the sealing strip (120).

[0031] The sealing strip (120) is preferably made of TPV or EPDM material, which has good resilience, aging resistance and UV resistance. Its body structure has a hollow cavity, which can generate deformation under compression to absorb gap changes.

[0032] II. Structure of the Pressure Adjustment Mechanism

[0033] like Figure 3 As shown, the clamping adjustment mechanism (130) includes an adjusting screw (133), a limiting slider (131), and an elastic element (132).

[0034] The adjusting screw (133) passes through the mounting hole (160) on the aluminum profile and extends into the profile, and is threaded to the limiting slider (131), which can be adjusted by external rotation;

[0035] The limiting slider (131) is square or rectangular, with one end in contact with the inner side of the sealing strip (120) and the other end opposite to the elastic element (132);

[0036] The elastic element (132) is a compression spring or a corrugated washer, which is located between the slider and the inner wall of the profile to provide thrust and cushioning functions.

[0037] During adjustment, the user rotates the adjusting screw (133) using a hex wrench or power tool, causing the slider (131) to move forward or backward, thereby generating different clamping forces on the sealing strip (120). After adjustment, the elastic element maintains its stable state, preventing it from rebounding and loosening.

[0038] III. Assembly and Adjustment Process

[0039] During the initial installation stage, the sealing strip (120) is embedded into the groove (110) of the aluminum profile body (100);

[0040] Based on the actual gap between the sealing strip and the docking component (140), the position of the slider (131) is finely adjusted by adjusting the screw (133) to achieve effective clamping of the sealing strip;

[0041] If a seal failure is found during use, the adjusting screw can be finely adjusted through the adjustment port or the sealing strip can be replaced without disassembling the main structure.

[0042] IV. Expansion of Practical Scenarios

[0043] This structure is suitable for applications requiring high sealing performance and exhibiting dimensional deviations, such as vertical joints in building curtain walls, intersections between door and window frames and beams, and nodes in prefabricated components. It can also be applied to scenarios with high dynamic sealing requirements, such as skylights, windows, and watertight doors, demonstrating broad adaptability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
