Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a modular double-layer curtain wall. Background Technology

[0002] In recent years, with the rapid development of building industrialization and green energy-saving technologies, curtain wall systems, as a key carrier of building envelopes, are evolving towards modularization, prefabrication, and high performance. Traditional double-layer curtain walls, by constructing a closed cavity formed by two layers of curtain walls on the building facade, utilize the air thermal pressure effect to achieve natural ventilation and thermal buffering, offering significant energy-saving advantages compared to single-layer curtain walls. Research by the International Energy Agency (IEA) indicates that optimized double-layer curtain wall designs can reduce building heating and cooling energy consumption by 25%-40%, making it one of the core technological pathways for ultra-low energy buildings.

[0003] Existing modular double-layer curtain walls generally suffer from low assembly efficiency, cumbersome procedures, and poor structural stability during construction and installation, severely restricting their application in high-rise buildings and prefabricated scenarios. Traditional curtain walls often employ separate, independent structures for the main and secondary frames, lacking standardized interface designs. Installation requires point-by-point fixing via welding or bolts, necessitating repeated adjustments to alignment accuracy, which is particularly time-consuming and labor-intensive, especially in high-altitude environments. Furthermore, the reliance on single mechanical fixation (such as bolt tightening) between frames results in weak resistance to lateral displacement, making them prone to misalignment under wind loads or temperature deformation. This hinders subsequent glass installation, further slowing down construction progress. Therefore, we propose a modular double-layer curtain wall. Utility Model Content

[0004] The purpose of this invention is to provide a modular double-layer curtain wall to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular double-layer curtain wall includes a main frame, two sub-frames symmetrically arranged on both sides of the main frame, and two glass panes sandwiched between the main frame and the sub-frames. The main frame has cavities on both sides that are connected to each other. Each of the two cavities on both sides and located on the outer wall of the main frame has an installation limiting cavity. The inner side wall of the sub-frame has an installation abutment block arranged around the installation limiting cavity at a position corresponding to the installation limiting cavity. The installation abutment block is embedded in the installation limiting cavity and abuts against the four edges of the glass pane.

[0007] As a preferred embodiment of this utility model, the glass is embedded in the cavity, and the four edges of the glass extend into the mounting limiting cavity, and the mounting abutment block forms surface contact with the edge of the glass.

[0008] As a preferred embodiment of this utility model, the main frame has snap-fit ​​grooves on both sides, and the inner side wall of the sub-frame has snap-fit ​​blocks on the corresponding positions of the snap-fit ​​grooves. The snap-fit ​​blocks engage with the snap-fit ​​grooves to fix the sub-frame.

[0009] As a preferred embodiment of this utility model, the cross-section of the snap-fit ​​block is a trapezoidal protrusion, and the cross-section of the snap-fit ​​groove is a matching trapezoidal groove.

[0010] As a preferred embodiment of this utility model, the outer wall of the main frame is provided with multiple threaded grooves at intervals around its perimeter.

[0011] As a preferred embodiment of this utility model, an installation groove is provided on the outer wall of the sub-frame at the position corresponding to the threaded groove, and a through hole is provided at the bottom of the installation groove. A bolt passes through the through hole and is threadedly connected to the threaded groove, thereby further strengthening the connection between the main frame and the sub-frame.

[0012] As a preferred embodiment of this utility model, a cover plate is snapped into the opening of the mounting groove, and the surface of the cover plate is flush with the outer wall of the sub-frame.

[0013] As a preferred embodiment of this utility model, the main frame and the secondary frame are made of aluminum alloy profiles, and the glass is double-layered hollow tempered glass.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the modular snap-fit ​​design of the main frame and sub-frame enables rapid alignment and installation, reducing adjustment time. Simultaneously, the combined use of the installation limiting cavity and the installation abutment block simplifies the glass installation process. The intermediate layer formed by the double-layered hollow tempered glass and the main frame cavity works synergistically to effectively block heat conduction and noise penetration, balancing summer heat insulation and winter heat preservation needs. This improves the building's indoor thermal and acoustic environment, achieving a dual optimization of energy saving and comfort. The snap-fit ​​block and snap-fit ​​groove connect the main frame and sub-frame. Based on the snap-fit, bolts pass through the through-hole of the sub-frame's installation groove and lock into the threaded groove of the main frame, forming a dual guarantee mechanism of mechanical fixing and snap-fit ​​self-locking, thereby further strengthening the connection between the main frame and sub-frame.

[0025] Example 1

[0026] like Figure 1-4As shown, this utility model provides a technical solution: a modular double-layer curtain wall, including a main frame 1, two sub-frames 2 symmetrically arranged on both sides of the main frame 1, forming a stable double-layer support system through the symmetrical distribution of the sub-frames 2, ensuring the overall structural stress balance of the curtain wall and reducing the risk of deformation, and two glass panes 3 sandwiched between the main frame 1 and the sub-frames 2. The main frame 1 and the sub-frames 2 are made of aluminum alloy profiles, and the glass panes 3 are double-layered insulated tempered glass. The lightweight and corrosion-resistant aluminum alloy frame combined with the sound insulation and heat insulation performance of the double-layered insulated glass 3 achieves synergistic optimization of the curtain wall's lightweight and energy-saving performance. Cavities 101 are opened on both sides of the main frame 1, and the cavities 101 are connected. The two glass panes 3 are respectively located in the corresponding cavities 101 on both sides, forming an intermediate layer between the two cavities 101. The intermediate layer can effectively block the conduction of heat between the inside and outside, reduce the heat conduction of solar radiation in summer and the indoor heat loss in winter, significantly improve the overall thermal insulation performance of the curtain wall, and weaken the penetration of high-frequency and low-frequency noise, thus improving the building's thermal insulation performance. Indoor acoustic environment quality; Installation limiting cavities 102 are provided around the outer perimeter of both side cavities 101 and on the outer wall of the main frame 1. Installation abutment blocks 201 are provided around the inner wall of the sub-frame 2 at positions corresponding to the installation limiting cavities 102. The installation abutment blocks 201 are embedded in the installation limiting cavities 102 and abut against the four edges of the glass 3. The glass 3 is embedded in the cavity 101, and the four edges of the glass 3 extend into the installation limiting cavities 102. The installation abutment blocks 201 and the edges of the glass 3 form surface contact. Through the installation limiting cavities... The use of 102 in conjunction with the mounting abutment block 201 prevents the glass 3 from shifting under external forces such as wind pressure and temperature changes. The edge of the glass 3 extends into the mounting limiting cavity 102, further restricting the lateral displacement of the glass 3 and improving the overall structural stability of the curtain wall. In addition, the mounting abutment block 201 forms a surface contact with the edge of the glass 3, which can evenly disperse the local stress generated by the load or thermal expansion and contraction of the glass 3, reduce the risk of cracking caused by stress concentration at the edge of the glass 3, and reduce fatigue damage at the frame connection.

[0027] Example 2

[0028] like Figure 1-4As shown, this utility model provides a technical solution: a modular double-layer curtain wall, in which the main frame 1 has snap-fit ​​grooves 4 around its two side walls, and the inner side wall of the sub-frame 2 has snap-fit ​​blocks 401 around its corresponding positions. The snap-fit ​​blocks 401 engage with the snap-fit ​​grooves 4 to fix the sub-frame 2. The cross-section of the snap-fit ​​blocks 401 is a trapezoidal protrusion, and the cross-section of the snap-fit ​​grooves 4 is a matching trapezoidal groove. Through the cooperation of the snap-fit ​​blocks 401 and the snap-fit ​​grooves 4, the main frame 1 and the sub-frame 2 are connected, while the lateral displacement of the sub-frame 2 caused by wind pressure or vibration is effectively suppressed, thus improving the curtain wall's resistance to deformation. The outer wall of the main frame 1 has multiple threaded grooves 5 spaced around its perimeter, and the sub-frame 2... An installation groove 6 is provided on the outer wall corresponding to the threaded groove 5. A through hole 601 is provided at the bottom of the installation groove 6. Bolts pass through the through hole 601 and are threaded to the threaded groove 5. Based on the snap-fit ​​connection, the bolts pass through the through hole 601 of the installation groove 6 of the sub-frame 2 and lock with the threaded groove 5 of the main frame 1, forming a dual guarantee mechanism of mechanical fixation and snap-fit ​​self-locking, thereby further strengthening the connection between the main frame 1 and the sub-frame 2. A cover plate 602 is snapped at the opening of the installation groove 6. The surface of the cover plate 602 is flush with the outer wall of the sub-frame 2. By snapping the cover plate 602 at the opening of the installation groove 6, the bolt connection point is completely covered, keeping the exterior facade of the curtain wall flat and without protrusions, making the appearance more beautiful.

[0029] The working process of this utility model is as follows: When using a modular double-layer curtain wall, it includes a main frame 1, two sub-frames 2 symmetrically arranged on both sides of the main frame 1, forming a stable double-layer support system through the symmetrical distribution of the sub-frames 2 on both sides, ensuring the overall structure of the curtain wall is subjected to balanced stress and reducing the risk of deformation, and two glass panes 3 sandwiched between the main frame 1 and the sub-frames 2. Cavities 101 are opened on both sides of the main frame 1, and the cavities 101 are connected to each other. The two glass panes 3 are respectively located in the corresponding cavities 101 on both sides, forming an intermediate layer between the two cavities 101.

The glass 3 is embedded in the cavity 101, and the four edges of the glass 3 extend into the installation limiting cavities 102. The installation abutment blocks 201 and the edges of the glass 3 form surface contact. Through the cooperative use of the installation limiting cavities 102 and the installation abutment blocks 201, the glass 3 is prevented from shifting under external forces such as wind pressure and temperature changes. The glass 3 extends into the installation limiting cavity 102, further restricting the lateral displacement of the glass 3 and improving the overall structural stability of the curtain wall. The main frame 1 has snap-fit ​​grooves 4 on both side walls, and the sub-frame 2 has snap-fit ​​blocks 401 on its inner side wall corresponding to the snap-fit ​​grooves 4.

The snap-fit ​​blocks 401 have a trapezoidal protrusion in cross-section, and the snap-fit ​​grooves 4 have a matching trapezoidal groove in cross-section. Through the cooperation of the snap-fit ​​blocks 401 and the snap-fit ​​grooves 4, the main frame 1 and the sub-frame 2 are connected, while the lateral displacement of the sub-frame 2 caused by wind pressure or vibration is effectively suppressed, improving the curtain wall's resistance to deformation. Force; then, bolts are used to thread the main frame 1 through the through holes 601 in the mounting grooves 6 around the sub-frame 2 and the threaded grooves 5 around the main frame 1. Based on the snap-fit ​​connection, the bolts pass through the through holes 601 in the mounting grooves 6 of the sub-frame 2 and lock with the threaded grooves 5 of the main frame 1, forming a dual guarantee mechanism of mechanical fixation and snap-fit ​​self-locking, thereby further strengthening the connection between the main frame 1 and the sub-frame 2; a cover plate 602 is snapped into the opening of the mounting groove 6. The surface of the cover plate 602 is flush with the outer wall of the sub-frame 2. By snapping the cover plate 602 into the opening of the mounting groove 6, the bolt connection point is completely covered, keeping the exterior facade of the curtain wall flat and without protrusions, making the appearance more beautiful.
